A Sensual Summer Session

Literotic asexstories – A Sensual Summer Session by Parker Sunday,Parker Sunday My sister Kim was 7 years younger than I, and thus we did not have a lot in common. When I hit puberty she was starting school. When she hit puberty I was in college. Oh, we shared the usual family things, birthdays, holidays, vacations and such. But our interests were years and worlds apart. Now and then I would help her with some math or science and I would answer any questions she would have about being grown up, but due to the age difference we rarely played together or watched the same movies or went places together. She was just the kid sister and I was her big brother.

When she was 15 and starting to get into dating she would ask my advice on how to handle various situations. She had not had a lot of experience and was curious, as are all kids that age. Kim was about to enter the period of high school when social as well as sexual items play a large part in a young girls life. It was also the time when your academic performance would determine what college you could attend, what kind of scholarships you would receive, and therefore likely set the tone of the rest of your life.

Kim confided in me that she did not seem to be as boy crazy as most of her classmates and wanted to know what I thought on the social versus academic question. Having just graduated from Penn State and about to enter grad school, I said, “Well, I feel the academics are highly important at your age, and there will always be time after high school to worry about the guys. And besides, most high school boys are so inexperienced and not yet refined in matters of the heart, which you really would not be missing a lot if you spent your time on the books and not the jocks.”

This seemed to reinforce the way she was leaning on the subject, she said, “Thanks for the help.”

Three years later, she graduated 2nd in her class with a full academic scholarship at a major university. I had just finished grad school and had a nice job lined up. So that summer we spent a couple weeks at our cabin in the mountains of western North Carolina before I had to go out and start working full time. Our folks were working in the city, but they wanted us to have this last time together before I started my new job.

The cabin was rustic and small, and Kim made a point of allowing me to catch a look of her nude a few times. I didn’t think much of this, she was still just my kid sister showing off a bit, but what the heck, most any 25-year-old guy likes to see nude 18-year-old girls. Most every night after we had gone to bed, it was so quiet in that cabin in the woods, I would hear her moaning in her room a few minutes after retiring. I knew that my little sister Kim was not a little girl anymore.

One afternoon we were having a summer thunderstorm, so we were forced to stay inside with little to do. Kim said to me, “Can I ask you a question?”

I replied, “You just did” so she threw a small pillow at me. I said, “So what’s your question?”

She replied, “Do you think that I’m pretty?”

I said, “You are the prettiest sister I have,” and that got me another pillow.

“Come on now, be serious,” she yelled, so I cut the joking and told her that she was above average in looks and that she was about fully grown now and would continue to improve as she got a bit older and a bit more self confidence.

We continued to talk about dating and boys and sex and masturbation. Kim confided in me that she had not had any sexual contact with any boys yet and was afraid that she would make a fool of herself the first time around. I assured her that we all have those fears before hand but when the time comes to just go with the flow and do what you feel like doing.

At this point she paused for about 20 seconds, and then unbuttoned the three buttons on her blouse and took it off and set it on the couch next to her. I wasn’t sure what to say, so I sat waiting a bit, looking at her sitting there in her ice blue bra and mid thigh skirt. She looked at me, blushing a bit, and softly asked me if I would play with her titties.

I replied, “I’m your brother.”

She quietly said, “But I want you to teach me what it’s like.”

“No, it’s not right for me to do that with you,” I replied. She just sat there for a minute not knowing what to do.

“Please,” she said, “I need to learn, I didn’t date a lot in high school, and I want to know what’s what when I get to college. And besides who better to teach me than you.”

I could feel my cock stirring a bit, even though I didn’t have any sexual feeling for my kid sister. Yet here we were, sitting close to each other, and her bra and tits begging for some attention. I thought back to our discussion about boys and sex and school 3 years ago. Kim’s breasts had grown since then, and it seems so did her interest in sex. I’m thinking about it, which no one would know, but just couldn’t. “Look,” I said, “I’m the quote adult here, and it’s my responsibility to look after you, not take advantage of you.”

A pout was on her face, and she said, “But you aren’t taking advantage of me, you will be teaching me. And I’m 18 now, so I am as much an adult as you are. And,” she continued, now with an almost evil look on her face, “if you don’t do it, I’ll tell Mom that you did.”

I gulped, and thought about what she just said and her look while saying it. It was true that I would just be teaching her a few things, just like the math and science, and it was an awful threat she made, threatening to say that I did it if I didn’t do it. “But …”

She snapped back, “No buts, I’ll tell Mom you forced me. And if I do, there goes you car graduation gift, and the rest of your being a part of the family.”

I was stumped, what was I to do. “Just what is it you want me to do?”, I asked.

“I’m not sure, that’s what I want you to show me, what boys do. What do you do with a girl when you are making out with her?”

Considering the situation and the consequences, and I knew that Kim would follow through on her threat, I said, “Well, OK, but I’m only going to teach you the early stuff, I’m not going to have sex with you, I’m not going to fuck you.”

Kim’s small mouth made the most wonderful smile I have ever seen it make, and she reached over and gave me a small kiss on the cheek. As she did, her silky blue bra pressed against my arm, and I could feel the warmth of her breast. Well, here goes, I thought, and reached my hand over and gently cupped her left breast in my hand. Kim jumped at first, then realized that I was in fact going to do what she wished, and she pushed a bit against my hand and scooted a bit closer to me. I let my hand roam over her soft silky bra, gently squeezing her and running my finger back and forth over her nipple.

It was strange that Kim, without knowing it, was wearing the kind of bra I liked the most. I dislike those with all the lace as they are scratchy on my hand and I just like the nice smooth ones so much more. I kept rubbing her nipple with my finger, feeling it get hard as I did so. I smiled at her and she smiled back and kind of cooed to me. I could tell that she was enjoying her lesson. And my cock was telling me that the teacher was too.

I had Kim stand up and face me, and then come and sit on my lap, with her legs straddling me, one outside of each of my legs. Now I could use both hands on both of her titties, and just gentle squeezed them and played with them and made both of her nipples hard and erect. Kim’s eyes were closed, and she was making a soft happy humming sound as I toyed with her bra.

After about the first minute of doing this I was so uncomfortable that I had to take my right hand off of her left tit, reach down into my briefs, and allow my cock to stand upright. My hand went right back to her bra and gave her left breast a nice full fondle. She opened her eyes as if to ask what that was about and I smiled and whispered that everything was fine and that this was to be expected under these conditions. She chuckled and closed her eyes and continued her little noises as I continued to play with her nice soft tits.

After about ten minutes of this, I decided it was time to move on. I moved my right hand over to her side, gently caressing her skin, and slowly reached behind her. My fingers reached the center of her back, and in one movement that I can best describe as like clicking your fingers, grabbed the bra strap hooks, pulled then together and released them, all in a split second, and the bra was undone. I slowly moved my right hand up to the strap on her shoulder, while still caressing her right breast with my left hand. Kim instinctively moved her body as she would anytime when removing her bra, without even realizing that she was doing so. With just a slight touch of my right hand, the bra fell free of her left tit and the strap slid down her arm, followed by the right cup pulling away from her body as my left hand continued to gentle fondle her. I was now holding her bra in my left hand as I squeezed it right off her tit. In one quick movement, I tugged the bra away from her body, the right strap gliding down her arm and over her wrist and I let the bra drop to the floor.

I then moved my left hand back to Kim’s right breast, softly caressing her smooth skin, and let my hand slide behind her back. I pulled her slightly forward, while leaning my head towards her and engulfed her right tit in my mouth, running my tongue around in circles around her nipple. Kim let out a little gasp as I did this, and relaxed while kind of shoving her soft tit a bit deeper in my mouth. My right hand was all over her left tit, gently cupping, squeezing, and caressing her wonderful flesh. I would take her nipple and play with it with my fingers while playing with her other nipple with my tongue. I was also kind of humming, going mmmmmmm, mmmmmmmm, mmmmmmm, as I sucked on her bare tit.

To get a bit more comfortable, I pulled her lower body closer to mine, to the point that her crotch was tight up against mine. My stiff shaft was poking her pussy through three layers of cloth. She squirmed a bit to get comfortable and I could tell that she liked having my cock throbbing against her cunt. It must have been a full five minutes before I released my lip lock on Kim’s right titty. I looked her in the eyes and asked if she were enjoying her lesson.

She smiled and in a voice deeper than I had ever heard pass her lips replied, “Oh, yes”, very softly so that someone ten feet away would not have heard.

My arms were getting tired of being in the same position for so long, I moved my right hand behind Kim’s back, slipped my left hand over her right tit, and gave a couple flicks of my tongue to her left nipple. I then stopped, looked her straight in the eye, and said, “Now, you must make a promise right now, before anything else, that you will never, ever, make a threat of telling Mom that I forced you to do anything.”

Kim giggled softly, and still in the husky but quiet voice said, “I promise.”

At this I flexed my cock three times knowing that she could feel it through her cotton panties, we both smiled at each other, and I put her left tit in my mouth and started feasting while my left hand was having a fine old time on her other tit.

Briefly I thought to myself why did you not want to do this. I started to reply to my own question something about being the adult and big brother, when I felt Kim’s pussy kind of spasm against my cock. All thoughts of being the responsible adult quickly faded, overwhelmed by the feeling of warm wet where our crotches hugged one another.

I did a lot of my humming on her titty and now and then would gently nibble her nipple while playing with the other with my fingers. Kim was as soft and gentle as a young kitten as I caressed her young body. There were four times I felt her gasp, breath deep, and shudder as we held each other for a long time.

A loud clap of thunder and simultaneous bright flash of light shook us back to reality. We smiled at each other and I asked Kim if she enjoyed her lesson and she just nodded her head and grinned. She wiggled her cunt against my crotch, pushed a bit and then stood up, picking up her blouse and reaching down and retrieving her bra from the floor. She reached over with the bra in her hand and softly touched it to my face and lips and said, “My panties are all wet.”

I looked at my own lap and saw a damp spot, unable to tell how much of it was her pussy juice and how much was my own pre-cum. “You’ll do just fine when the time comes, you have nothing to worry about.”, I said. Her only reply was a bit of a grin, as she went off to change her panties and I went in to put on dry clothes myself.

* * *

The next morning we were walking through the woods, away from the cabin and the road and most everything man made. The air was fresh and clean from the storm the prior day but there was no trace of the rain, everything having dried out overnight after the frontal passage.

Kim and I talked about lots of things as we walked through the woods. We came to a favorite spot where we were in a clearing overlooking the valley formed by the mountains. We sat down to rest and enjoy the view.

We were talking about sex and boys and masturbation and dating again, and Kim asked how I knew what to do or not do. I told her that I had decided along the way that if it is with someone you like or love, if you both want to do it, and it feels good and doesn’t hurt others, then to go for it. She seemed to think about this for a long time, then just replied, “Thanks.”

She continued, “I played with myself yesterday after we did our lesson, still wearing those wet panties. I just lie on the bed and kept rubbing myself for a long time. I came three different times. What about you?”

“What do you mean, what about me?”, I said.

“Did you play with yourself?”, she grinned.

“Well, no, not really. OK, a bit. I did grab my dick and rub it for about 30 seconds, but I didn’t jerk off until I came. Not then.”

“How often do you jerk off?”, Kim asked me straight out.

“Oh, every day.”, I said.

“Just once a day?”

“No, not always. Sometimes it’s once a day, sometimes twice. The most is five times in one day.”, I replied. “If it feels good, do it.”

And Kim chimed in, “Do it.”, in unison with me, and we both laughed.

“What about you Kim, how often do you masturbate?”, I queried. I was always curious about how often girls did it, but had never before had the nerve to ask any, and this was the perfect time to find out.

“Oh, almost every day”, Kim replied. “It depends. It’s mostly at night when I go to bed or in the morning when I first wake up. But if I’m real tired at night I just go to sleep, or if I wake up and have to get to school or go somewhere and don’t have time I just don’t do it. And sometimes when I am taking a shower, I use the soap and the spray shower hose” she continued. “But mostly it’s when I’m alone in my own bed. You know if it feels good then …”, she chuckled.

“Did you ever get caught?”, I asked her.

“No, what about you?”

“Yes, once”, I replied. “Mom walked in on me when I was doing it. I didn’t know what to do”, I said. “But Mom was cool, she just smiled at me, turned around and left my room. And you know what’s funny now that I think of it? Mom said softly as she was leaving me alone, “If it feels good.”. ” And we both laughed.

Kim all of a sudden got a strange look on her face, and was lost in thought for a bit. She then said, “Can I ask you something else?”, I nodded. “Can I do it right here, right now, with you watching?”, she asked, very softly. “I’d really like to have you watch me”, she said.

“Well”, I replied, “If it feels good and you are with someone you like and it doesn’t hurt anyone, then go for it.”

Without a word, Kim pulled her skirt up around her waist, moved her right hand between

her legs, and started to rub herself through her white cotton panties. She was leaning back, resting her body on the sloping ground, almost as if she were half sitting and half lying on a sofa. I stretched out on my side, propping my head in my hand, my elbow on the ground supporting my forearm, with a great view of Kim’s thin panties and her hand moving up and down giving herself pleasure. Her eyes were closed but mine were locked on the action between her legs. Again I had to reach inside my shorts and let my cock point at my navel. I could see the ridge of Kim’s pussy lips through her panties when her hand wasn’t blocking my view. I just lay there, watching my little sister play with herself, without saying a word. I could see the pleasure on her face when I looked at it, but mostly my eyes were glued to her crotch. As she continued I noticed that her strokes were becoming shorter and more rapid, and at times her hand would stay still and just one finger would be flipping up and down on her clit.

I was thinking how I would have liked this to be one of my girlfriends from college that I was watching so that I could join in the action at the right time, but alas, it was still just my little sister Kim. I also realized that I was gentle rubbing my cock with my right hand, as I lay on my left side watching Kim do her thing. What the hell, I thought, if it feels good …

Kim’s breathing became faster as she neared her climax. She was squirming around a bit and briefly opened her eyes to see that I was watching. She may have done this before, but my eyes were not on her eyes, they were too busy drinking in the sight of her playing with her own pussy. With a loud moan, Kim all of a sudden clamped her legs together, squeezing her hand tight between them and kind of half rolled over on her side.

I could no longer see her hand or the wet patch on her panties, but I looked at her face and saw the happiest look on her that I had ever seen. I smiled at my sweet little sister, as she slowly finished her climax. She didn’t move for two minutes, but then stirred a bit and said, “Um, that was great. Did you like watching?”

I nodded and said, “Oh yes, I sure did.”

Kim said to me, “About yesterday, after our lesson, you said you didn’t jerk off. What did you do?”

“Nothing then”, I replied, “but last night when I went to bed I took care of my throbbing hard on. I was thinking of sucking on your tits, and mentally pretended that it was that real great looking girl that does the weather report on the TV whose tits I had been sucking. Then this morning I did it again. Typical masturbation fantasy stuff.”

Kim looked a little hurt by my statement and I could see the ‘what about me’ question running around in her mind. I continued, “But it was your tits that I was sucking on yesterday, your very soft beautiful titties, but the teacher should not get too involved with his student. And the best thing about fantasies is that the cast can change in an instant. You know that.”, I smiled and she relaxed and smiled back at me.

Her eyes swept down to my crotch and I saw her looking at the outline of my still firm cock through my clothes. “What’s it feel like?”, she asked. I wasn’t sure exactly what the what was that she was referring to. “Your cock, what does it feel like?”

I wasn’t sure what to say. The skin is skin, when its hard its hard and when its soft its soft. When I touch it, it is the dick that gets the feel sensation, not the fingers. I kind of stammered, “Well, it depends …”

Kim said, “I want to touch it”.

I wasn’t sure about this. After all, yesterday was far more than a big brother should be doing with his kid sister. Now she wants to touch my Johnson.

“Look”, Kim said, “at some point you didn’t know what tits feel like, at some point you touched you first tits. I want to touch you, to see what it feels like. And I want you to rub my pussy.”

I was perplexed. What Kim was saying was true. And it was certain that she had yet to touch a cock. But now she wanted me to be rubbing her pussy as well. “You look”, I said. “I told you I wasn’t going to fuck you, that we were not going to have sex. What we did yesterday was enough. I’m your brother, not your boyfriend.”

“What we did yesterday was beautiful”, she replied. “You are teaching me what I need to know so that when I have a boyfriend, I don’t look like a child. Would you rather have me learn from some punk that is all hands and doesn’t give a shit about me or how I feel?”

And that was the problem and we both knew it. Only I could show Kim what she needed to learn in a way that would be loving and caring and not potentially fuck up her sex life for the rest of her life.

We were alone in the mountains, it was a nice summer day, and we had been talking about sex so much for the past day, and yesterday I had her tits in my mouth and her cunt smashed up against my cock. Would it cause harm? No. But it could lead to some if we didn’t continue the lesson.

“If it feels good, if you are with someone you like or love, and if it doesn’t hurt anyone”, she kind of quoted me saying yesterday, “then go for it. Well?”

I was silent for a full minute, trying to process everything that was happening to me. I loved my little sister; she loved me. I was the teacher; she was the student. It would feel good. It wouldn’t hurt, except my what’s right and wrong thinking, and I could let that go for the right reason. And Kim had just convinced me that this was the right reason. “All right,” I said, “but I’m still not going to fuck you. That will be for some lucky guy sometime when you are older and in love. And it will be your choice, not his or mine. Understand?”

Kim lay there looking at me, with such an angelic look on her sweet little face. She slowly nodded her head and said, “Understand.”

Now what, I thought to myself. When, where, what, how? “Do you want to do it here and now?”, I asked.

She shook her head, and said, “No, I have to pee, and I think it would be safer if we were back at the cabin with the door locked, so no one could see us.”

I had to agree. I stood up, a slight bulge still showing in my pants, looked down at Kim with her skirt still half up around her middle, and her white cotton panties still showing a large wet spot from her earlier activities. I reached out a hand to her, she grabbed it and I helped her to her feet. She stood there in front of me, looking up to me with her warm light blue eyes, and put her arms around me in a loving hug. I couldn’t help but think about her titties pressing into me again. Yesterdays lesson was so nice, and I really liked her tits touching me. I put my arms around her, returning her hug, and squeezing her tits with my chest. She released her arms from around he, and as she was pulling away, one of her hands brushed against my pants, and her hand softly cupped my cock for a brief moment. The little imp, I thought, she just copped a feel. She acted as if nothing happened, and I let it ride. She would have her hands all over my cock before the day was done.

It took us half an hour to get back to the cabin. Normally it would have taken 10 minutes more, but Kim said she really needed to pee and would not go out in the woods, so we alternated running and walking, with her running near full speed the last 200 yards to the cabin. I let her run ahead. The cabin only had one bathroom, and I wasn’t in a rush to use it. I took time outside the cabin to pick up a few things that had been blown around in the thunderstorm yesterday, so when I entered the cabin, Kim was just coming out of the bathroom, a much more relaxed look on her face they when I last saw it a few minutes before.

I grabbed a nice fresh North Carolina peach from the kitchen and ate it quickly, washing the juice off my hands in the kitchen sink when I was done. Kim had watched me start to eat the peach, then disappeared into her bedroom without saying a word.

It was my turn to use the john, and after I went in and closed the door I saw some white cotton panties hanging half in and half out of the clothes hamper. I grabbed them with one hand while pulling out my dick with the other and started making foam bubbles in the toilet water. I quickly inspected the panties and confirmed that they had a large wet spot on them, so they were the ones Kim had been wearing on our walk in the woods. I finished and put my dick back in my pants, then pulled it out again. I held my dick in one hand and rubbed the cotton panties up and down its length with the other. With a smile on my face, and you might say a smile on my dick as well, I tucked it back in my shorts before it got too big and hard to handle. I then rubber my face with a dry portion of the thin cotton and kind of sniffed at them at the same time, smelling Kim’s sex juice on them. I wasn’t quite sure why, but I then slipped them into my pocket and walked out of the john.

Kim was sitting on the couch, just finishing an ice cream bar. She was wearing the shortest skirt I have ever seen her wear, a white mostly see-through blouse with a simple white cotton bra under it. Usually Kim or other girls would wear something else under such a blouse for modesty, but it was clear that Kim wanted me to see as much of her bra and titties as possible. My cock had been a bit enlarged from the panty encounter in the john a minute ago, and grew a bit more as I looked at my little sister sitting there in such a sexy outfit.

She asked me if I could grab something for her to wipe her fingers on but I just went over and sat next to her without heeding her request. I reached and took her small hand in mine and lifted it to my face. I then slowly took one of her fingers and put it in my mouth, gently sucking it clean, tasting the ice cream but enjoying the feeling of the sucking even more. I did this to the other two sticky fingers as well, taking my time doing so. By the time the third finger was entering my mouth, Kim understood exactly what this part of the lesson was about and gently was sucking on one of my fingers as well, without me knowing how she even got it in her mouth.

Kim’s skirt was, as I said, very short, and very full, almost like a skaters skirt. With our movements on the couch and the finger sucking and all, the tiny skirt was now not covering half of her and I could see that she was now wearing very pale yellow mostly see-through panties of nylon or silk or some such fabric. I could see some of her bush showing through the panties, and felt my cock stir some more in my own shorts. I finished her fingers somewhat to her disappointment, and said, “OK, now what would you like to do?”

“You’re the teacher, I’m the student, if it feels …”, her words trailing off to nothing. I couldn’t help but smile as she repeated my words from yesterday.

Kim was seated on the couch with her back leaning fully back, her legs somewhat apart, and her feet flat on the floor. Her skirt was askew showing me the pale yellow panties and the bit of cunt hair. The student waiting for the teacher to continue the lesson. I was sitting sideways on the couch, my left leg folded under me, my left arm was around Kim’s shoulder and behind her neck with my hand resting on her far shoulder. My right hand was free to do as I pleased.

I took my hand and touched her face, slightly turning it to face me a bit more. I leaned over and kissed her in a way I have only kissed my lovers, never my kid sister. After the kiss, I returned to a more upright position and Kim rested her head back on my left arm, relaxing the best she could under the circumstances.

I let my right hand come down slowly from her face sliding down her neck and stopping on her tit. I rubbed her nipple through the bra until I could feel and see it poke against the see-through blouse. With one caress and compressing of her full breast, my hand then went down to her right hand, taking it and moving it onto and around my cock, and I squeezed her hand gently so that she was squeezing my cock in her hand. The look on her face was priceless as she realized what she was doing. I just grinned a bit and nodded my head in approval.

Words were not necessary or even wanted. This was a lesson of touch and feel. Her hand was now acting on its own, with no further direction required on my part. I flexed my cock twice, showing my kid sister that it had some, although limited movement ability in its fully erect state. Her hand was exploring the full length of my cock, and her fingers slipped down a bit to gently explore my balls. With her full hand back up on my cock, I slightly thrust my hips a bit and she starting stroking my rod as if she had been doing it just right for years.

My hand came up and began working on her right titty, waking it from its passive state. Kim’s breathing was starting to become heavier and I knew she was enjoying every moment, as was I. I managed to unbutton her blouse with my one hand, spending lots of time on each of her titties, as she continued to play with my cock.

I shifted position a little, taking my arm from behind Kim, and moving my right hand between her legs. She let out a little gasp as my hand engulfed her pussy. She spread her legs a bit and moved a bit lower, her ass coming forward a touch to allow me better access to her mound. I had moved her skirt so that it was completely up out of the way, giving me full view of her tiny yellow panties. Using mostly my fingers held together, I rubbed her pussy up and down, up and down, responding to her reactions and she responding to my touch.

There was now no thinking about what was taking place on either of our parts; our bodies were just doing what feels good. My hand would caress her inner thighs and then return to her cunt. She continued to stroke my cock and hold it and squeeze it in a most loving way. Twice I felt Kim tighten her muscles and give that little shudder. When she did this she would squeeze my cock hard with her hand, and I was glad that it wasn’t my nuts she was squeezing. Kim’s yellow panties were completely wet and very slippery which just aided in the good feelings as I rubbed her little cunt.

I loved looking at her bra holding her breasts, the look on her face as I touched her body in new ways. I could move my head over and suck on one of her tits, right through the bra. This seemed to excite her and I knew it excited me. Finally at one point I took my hand and lifted her bra on one side sliding it above her titty and played with her nipple with my fingers and later with my mouth. I left her other tit covered with her bra, `cause it was a big turn on for me to play with a titty covered with a bra. God how I loved bras and loved the titties they held.

Kim’s constant playing with my cock was starting to get to me, and I knew that the lesson would not go on forever. I had to stop feasting on her tits or it would be all over and I didn’t want that just yet. My eyes went down to the yellow panties and I saw the dark area of the pale yellow, indicating the wetness. I looked around a bit more, trying to reduce my level of excitement so I wouldn’t cum yet, and for the first time I saw the top and sides of the panties. On each side was a small bow tied by two pieces of pale yellow fabric. I reached over and grabbed the end of one and gently tugged and to my delight it came undone just like a shoelace. I reached over to the other side and repeated the maneuver with the same results.

My little sisters very wet little yellow panties now kind of slid away from her pelvis, allowing me free access to her pussy. I thought to myself what the hell is a young girl who has never been fucked and never touched a cock before today doing owning a pair of see-through quick-off panties. Where do you even buy such things?

Returning my attention to the task at hand, I moved the now freed panties aside with a slight movement of my fingers and let my hand rub directly on her wet cunt. I slid a wet finger up and down her slit, fingering he clit and making her moan out loud. I slid the tip of my middle finger in her opening and withdrew it again. I repeated this a few more times, each time going a bit deeper inside her with my finger and then sliding my finger back up and rubbing her clit. With each movement of my finger on her she made louder and longer sounds, letting her pleasure flow.

While all of this was going on, I was aware that Kim had been messing around with my belt and zipper, but I was too involved with playing with her bare pussy and starting to finger fuck her that I really didn’t give a shit what she was doing to my clothing. At least she wasn’t rubbing my cock as much, which would have been too much for me to take along with her bare cunt. Now I realized that as I was opening her, she was also opening me without my full awareness. Now as I was finger fucking her bare cunt, she was yanking on my bare Johnson, fully as wet with pre-cum as her pussy was with her own pussy juice. My little sister, my student, had come to class prepared and ready for her lesson.

If it had been anyone other than Kim playing with me at that point I would have just repositioned us and started fucking her until we both came. But this was Kim, my little sister, and this was just a lesson on pre-lovemaking. She had nothing to worry about being with any guy, which is exactly what I thought from the start of this whole thing. But I wasn’t about to stop the lesson at this point.

My right hand was busy finger fucking her tight little cunt while my left hand was playing with her smooth white cotton bra covered tit. We could each tell that the other was getting nearer to the end, and she increased the speed of her hand on my cock head as I increased the speed on my fingers playing her cunt. All of a sudden, she clamped her legs together tight, keeping my hand from moving. The only thing I could still do was move a finger around in circles around her clit, which of course I kept doing. Her whole body tightened, her head fell back and a kind of scream came from her mouth. My free hand tightly squeezed her bra and tit, my fingers squeezed her nipple through the cotton bra cup and she clamped her fist on my cock and was jerking it as well as if I were doing it myself. The excitement of her coming was too much for me, and as she slightly relaxed the tightness of her grip on my cock, I started shooting cum. It was my turn to let out a great moan of pleasure as I spurted away.

Kim’s legs had relaxed a bit after her orgasm and my trapped hand was able to move a bit. It was mostly my hand just shaking as I was cumming, but I did manage to slip my finger in and out of her cunt hole a couple more times, which triggered an after shock in my sweet little sister and I felt her body shudder one more time.

We just kind of melted into a single mass of arms and legs and sweat and sex juice until we recovered from our orgasms and caught our breath. Kim still had my cock in her hand and I still had a firm grasp on her bra-covered titty. I was able to move my mouth over to her bare tit and slipped it in my mouth. God how I liked sucking tit. Kim was still gently stroking my cock, so that along with the tit activity kept me from going completely soft.

That part of the lesson, I decided, could wait for another teacher. For now I would let the student remain unaware, just as her sweet little cunt had yet to taste any cock pounding away at her innards. We remained enmeshed together, still playing with each other, sucking and stroking and rubbing for another half hour. We almost started up again full bore, but were both too spent to go that far.

I let her tit slip from my mouth, looked up at her soft glowing face, and said, “summer school is over.”

Kim leaned forward and kissed me, and said, “Yes it is, and thank you teacher. I think I can handle things from now on.”

We managed to separate our bodies and to stand up. She was wearing a bra, half on and half off, a very short full skirt with no panties left on her body. I was wearing a shirt, the front completely open and the buttons gone who knows where or when, and a bunch of something around my ankles that I had to step out of so I would not trip and fall. We then stepped towards each other and hugged each other.

Her tits were again pressing into me, and the smell of our sex covered us both. She touched my rod with her small hand and I responded by becoming a bit more erect. My cock rose to push against her bush and was begging for more. Kim blushed a bit and smiled up at me. I just shook my head and said, “No, I told you we are not going to do that. That is grad school, and you have a lot of undergrad work to complete before taking on such advanced subjects. And your tutor will not be around to help you.” With that we released our hug and just stood there looking at each other for a long time.

I went into the bathroom and got in the shower. I washed myself and stroked my Johnson. To my surprise, it sprung to life and in less than a minute of stroking I let lose another load of cum, thinking this time about me kid sister and not the weather girl on TV. I washed the cum off my dick and off the wall of the shower. When I got out of the shower, there was a pile of clean clothes waiting for me. What a great student I smiled. When I left the bathroom fully dressed, Kim was sitting at the kitchen table, fully covered in a terry cloth robe, waiting her turn in the shower. The couch was neat and there were no signs of any clothing or any of our activity. I reached over and softly ran my fingers down Kim’s cheek and jaw, and whispered, “Next.” She stood up and padded off to the bathroom.

I went into my room and saw that my pants were carefully folded and placed in my suitcase, and my shorts were in the dirty clothes hamper. I stretched out on the bed, hearing nothing but the water running as Kim was showering. I thought how nice it would be to be in the shower together, soaping each other’s bodies. But that was not allowed in my lesson plan. Just then I heard a pleasure scream come from the shower. So I wasn’t the only one to need additional relief after the fact. It had to be all that after play, The tit sucking and cock rubbing that almost got us going again. And that final hug when my cock was reaching for her pussy lips. Kim needed another release too and had just taken care of things. Life was good, but for the only time in my life I wished that one of us had been adopted.

It was only early afternoon, but I needed some rest after our long lesson. I slipped out of my pants and put them on the bed. I got under the sheet and closed my eyes and was thinking of Kim’s pale yellow panties and white cotton bra. Within five minutes I had grabbed a tissue from the box and was stroking myself while remembering my fine young sister being finger fucked by me a short time ago. I came again in about 2 minutes, and then fell asleep.

I woke up and it was 4 PM. A couple hours sleep, and I felt fine. As I became fully awake I became aware of something. Kim was in bed with me, behind me. She had come in while I was sleeping and crawled under the sheet, facing my back, and likely fell asleep herself. I turned over to look at her, and my moving stirred her awake.

“Hi.”, she said. “I wanted to nap too, but wanted to be with my big brother, so I came in here. I hope you don’t mind.”

“I don’t mind at all, Kim. You just surprised me a bit, that’s all.”

“Well, you surprised me too teacher, with all the stuff you managed to get into a single lesson. But it sure was a lot of fun. I never enjoyed any other class like I did that one.”

“Well, I certainly hope not.”, I replied.

“But I want to make sure I have the rules right.”, Kim said. “First if you want to.” “Second, ah, if it’s with someone your love.” “Um, oh, if it feels good.” “Then do it.”

“Well, that’s close.”, I said, “but I’m an easy grader, especially after our lesson today.”

“What did I miss?”, she demanded.

“Well, let’s see. If you BOTH want to. If it’s with someone you love OR LIKE. If it feels good. AND if it doesn’t hurt anyone. Then”

“GO FOR IT”, she nearly shouts.

“Yes.”, I replied.

“See, I got them all right.”, she bubbled.

“Almost.”, I said, but she was not paying attention. Kim had been lying with her head on the pillow and all but one arm covered by the sheet. I was lying facing her, my arm under my head a bit to aid the pillow and also covered with the sheet, except for my arms. We were within reach of each other, but neither of us had touched the other.

Kim started to move, and propped herself up on one arm. As she did, the sheet fell from the upper part of her body, and I saw that she was wearing a light flannel loose fitting print bra. It looked like some kind of slumber thing that she would wear to sleep in, not something that she would wear when she was dressed. It was really very low cut, showing the entire top of her breasts, and barely covering her nipples. And as I liked, the bra had no scratchy lace. I looked back to her face and saw that she had been intently watching me eyeing her tits and bra. “You like?”, she asked, grinning. I just smiled.

“OK, I’m ready for the final exam”, Kim says, leaving me somewhat puzzled as to what the heck she was talking about. She then reaches her hand towards my crotch and in so doing completely exposes one of the titties to my view.

“Whoa!”, I said. “What do you think you are doing?”

“I’m going to take my final exam, dummy. Now, you’re not allowed to help the student. All you are allowed to go is grade my performance.”, she says, again reaching for my crotch.

“Now wait a minute”, I protested, “What about the rules?”

“Rules, rules, all the rules say yes, dummy.”, Kim says

“Do they?”, I ask.

“Well, yeah. It’s someone I love, you big brother, it feels good, we both agree on that, and I want to, so …”

“What about the rest of it?”, I ask.

She stops and thinks for a moment, and says, “Oh yeah. It’s not going to hurt anyone. I promise I won’t hurt you.”

“But you missed one other part, if you BOTH want to. What if I don’t want to?”, I ask.

“Oh, you want to, I know it. Why wouldn’t you want to?”, Kim says, as she swings her body around where I can now see both titties, nipples and all, even though she is wearing that printed bra thingy.

“Well, I say I don’t want to. What are you going to do about that?”

“I’m not going to listen to your mouth”, she replies. “I’m going to ask your cock. It can’t fib to me or tease me by pretending that it doesn’t want to.”

Well, that pretty much settled things. When I first woke up I had a hard on, I must have been having REM sleep. I almost always wake up with a hard on. That’s just the way it is. And seeing Kim there in bed with me, and seeing that soft printed bra barely covering her, then seeing one tit then both, and thinking of what she wanted to do to me, my cock was screaming yes yes yes even if my brain and mouth were trying to say no. Before I could even process all this information, Kim’s hand had reached out and grabbed my cock and had her yes answer. And I had to admit to myself that getting a hand job from my kid sister would not be all that bad, I really would like it. And a bit of practice wouldn’t hurt her either, as long as it was she that initiated it.

She was now kneeling on the bed in front of me, her titties almost touching me. The sheet was completely gone from her body and she was moving it away from mine at that very moment. I looked down below her waist and saw that she was wearing a matching pair of panties, the soft flannel print, but these were anything but loose. They were so skimpy they barely covered her ass and cunt, and clung as tight as her skin. I don’t think that I will ever understand girls under things, and don’t really care. I just like to enjoy them, not understand them.

“Is it OK if I play with your tits while you play with my cock?”, I asked.

She smiled and said, “Yes, that’s OK, but that’s all you are allowed to do. That and cum when you are ready.”

How could I argue with that? My cock was crying to be stroked again by my little sister, the animal in me wanted to play with her cute titties, and all I had to do was sit back and enjoy it.

Kim was still kneeling in front of be, her small hands slowly were gently playing with my cock through my shorts, and I reached a hand over to one of her titties and started to fondle it, making love to it with my hand, sometimes outside the soft flannel bra and sometimes under it. Kim was going very slowly and I wished that she would speed it up a bit. But then I wanted it to last forever, to go on for the rest of the day it just felt so good. So I was really glad that she was going so slowly. And it gave me all the more time to play with her delicious tits.

Kim was a fast learner. She could tell when I began to get a bit too excited, and would pause or change the way she was touching me so as to delay my cumming. She too seemed like she wanted this to last a long time. Once she had one of her little shudders, which I was now thinking of as mini orgasms. I would have to ask her about these sometime later, when we were taking about stuff, not doing stuff. I wouldn’t do anything now to interrupt what was going on. The final exam was in progress, and was not to be interfered with in any way.

Then Kim did something that caught me off guard, She lowered her head, and started to rub her face on my cock, still through my shorts. She then put her lips on my rigid tool and started humming, again still through my shorts, but that didn’t seem to matter at all, it felt heavenly. I had never had anyone give me a hum job before, but knew that I would be teaching that technique to future females who happened to have their face around my cock. Kim and I had not ever talked about blowjobs, and I didn’t know if she even knew what they were. But that was not what I was expecting and was fairly sure she would not initiate oral sex, other that this great little hum thing she was doing to me. After about five minutes of that, my cock was twitching so much that Kim knew it was time to change activities. She lifted her sweet face from my cock looked up at me smiling, and put her hands on the top of my shorts and started to tug them down my body. I planted my feet and lifted my butt off the bed so Kim could slip my shorts off me. It took all of about seven seconds and they were gone.

Kim them moved her body so that we were touching side by side from our arms to our feet. She pressed her tits against my body and had one hand wrapped around my cock, gently jerking me off in a way that only a novice would do. I tried to pump my hips a bit, fucking her hand if you would, to get her to go a bit faster. But she would have no part of that. For the first time since I first grabbed her tits one of us spoke. She said, “No, no – not so fast. I’m running this show.” I just sighed. Only her second time with her hands on a cock, and already she was running the show. I closed my eyes, had a tit in my hand that was giving me great pleasure, and let my kid sister play her tune on my rod.

With my eyes closed, I noticed something that I had missed with them open. Kim was somehow flexing the muscles in her legs, slightly pushing or rubbing her legs together. I figured out that somehow she was masturbating herself without the use of her hands, since they were busy masturbating me. This made me smile but Kim didn’t see the smile on my face since she was looking intently at my cock.

We both could tell that things were coming closer. My entire cock and both her hands were covered with my pre-cum juice. Each touch of her hand to my prick sent electric chills through my lower body. My hands were grabbing her titties harder and harder, her nipples were hard and erect, and she tingled every time I would brush my hands across her nipples.

Kim knew it was time, and she slipped one hand inside her tight flannel panties, placing a finger in just the right spot, moving it in a way that only she could know. She increased the speed and tightness of her grip on my cock, and I squeezed and held her tits tight, one over the bra and the other under it. One finger on the hand outside her bra moved quickly back and forth over her nipple. Her other nipple was firmly placed in the palm of my other hand and I couldn’t do anything to excite it more, just squeezing and releasing her tit in time to her motions. My cock jerked in her hand three times, and she knew it was time to loosen her grip just a bit and increase the speed to finish things off. As she increased the speed on my cock, she also increased the speed of her finger inside her panties, and she started to cum. Knowing that she was cumming was all I needed and I let go. My sperm shot out and landed on both of us, but we didn’t know or care. We were totally involved in our orgasm and the feeling of the other having an orgasm at the same moment. For the second time that day, Kim and I just melted together in the afterglow, but refused to let loose our touch on each other.

I looked at the clock and was surprised to see that it was 5:30. I looked at her sweet face, smiled at her and softly said, “You passed.”

She replied, “Oh, I know that, but what grade did I get professor?”

Without a pause, I responded, “A +.” At that time we both closed our eyes, holding each other, her one hand still on my cock and my one hand still on her tit. And we fell asleep just like that.

I woke up and it was getting dark, must be something like 8 o’clock although I couldn’t see the clock from where I was. I of course had a hard on, and had to pee. But it did surprise me just a bit that I had another hard on, considering that I had come 5 times that day, and six times in the last 24 hours. Yet Johnson was alert and ready to go. Probably was wondering where the pussy was. All of this sweet sex and yet not a pussy or BJ to be had. I was able to get out of the bed I think without waking Kim. I walked slowly to the john, a bit sore but totally happy. An A+ indeed. Certainly extra credit for that hum job, I smiled as I recalled the wonderful feel of her vibrating lips on my cock.

I returned from the john and returned to the bed, getting in behind Kim and getting her in the spoon position for the first time. I slipped my arm under hers and cupped and held her tits in my right hand. My cock was actually limp for the first time all day, but I pressed it against Kim’s sweet little ass anyway, enjoying the feel of the soft flannel print panties pressing back against me. I actually felt a slight stir in my cock, but that’s all it was. It needed a little time before it was ready for any action.

My hand felt Kim’s nipples perk up a bit so I suspected that she may be awake. Sure enough, she moaned a little, and said, “I’m hungry.” I realized that I was very hungry myself, having nothing in my mouth but tit since the peach much earlier in the day. I remembered the sucking of the fingers, but discounted the ice cream on them. That was sex, not eating, and not enough calories to support a single erection.

I told Kim that I would be back shortly and slipped out to the kitchen. I grabbed some lasagna from the freezer and put it in the microwave and punched some buttons. I opened the fridge door, selected some cheese, and closed the door. I flipped the cheese on a platter, covered the rest of it with fresh fruit, and was back in my room before Kim’s tit could get cold from not having my hot hand holding it.

I said, “this is for starters, the lasagna will be ready before we have put a dent in all of this.” Kim again smiled at me and said thanks, grabbing some cheese first then some fruit. We then took turns feeding each other cheese and fruit and pretty much just looking at each other and remembering the events of the day. After a few minutes we heard the beep beep beep of the microwave calling us to the kitchen.

We slowly climbed off the bed and Kim headed for the kitchen. She was still wearing her matching bra and panty set and I quickly grabbed and stepped into a pair of boxer shorts as I followed her from my room. Kim removed the food from the microwave, grabbed some bread and quickly spread it with garlic butter and put it in the microwave. She punched in 1 minute, took those few seconds to serve the lasagna on some plates, opened the door to the microwave just before it beeped and added the garlic bread to our pasta dishes.

We sat facing each other, seeing one another in a way that we had never seen before, knowing that we would never see this way again. This was truly a once in a lifetime experience for both of us. We had become closer than ever before, and knew that we would soon part, never being able to return to this magic cabin in the mountains. Oh yes, we would both be at the cabin again in the future, it just wouldn’t be the same as our two day summer school.

We finished eating and cleaned up the kitchen, and Kim said to me, “What now?”, I said let’s sit on the porch and took her by the hand and led her outside. We settled down next to each other and enjoyed the cooler evening air on our almost naked bodies. She was leaning with her back on me and my arms wrapped around her body with her tits cupped in my hands. We didn’t talk. We didn’t need to. There was an unspoken bond between student and teacher. We spent an hour like that as the air got a bit cooler. Our tired bodies shivered within seconds of each other, telling us it was time to leave the porch and go inside.

Kim asked me what I wanted to do about sleeping that night, knowing it would be our last night alone together. I said what ever she wanted to do, that it didn’t really matter to me. Again me little sister had a surprise for me.

She spoke just four words, “If it feels good”, reached out and took me by the hand and led me into her room. Her bed was a bit larger than mine, softer, and had a nice down filled very soft and silky comforter on it. She stopped by the bed and turned and looked at me. We were about six feet apart, so I could see her whole body without having to look up and down. She reached and hooked her thumbs on each side of her panties and pulled them off. She then stood straight up, with me staring at her pussy fur with a grin on my face. She then took the panties, and turned them inside out and slipped them back on with what would be the front facing backwards. The very tight little panties were not cut to be worn backwards, but had enough stretch in the material to just about fit without being overly uncomfortable.

Kim then got into bed and motioned for me to do the same on the other side, which I did. “I want us to sleep together in my bed tonight. I want you to spoon me the way you did earlier. I want you to hold my tits in your hand. I want you to press your cock against my panties like you did before. And if you can, and if you want to, I want you to hump my ass, put your cock against my panties and fuck my butt. I think it will feel good. If you can, I want you to cum all over my panties. That’s why I put them on inside out and backwards. That way, if you can cum once more today, cum on my little panties, then I will always have your cum on them and then I can put these panties on and press your cum against my pussy when I want to remember our summer school. If it feels got, go for it.”

And with that Kim reached over and turned off the light. I could feel her move onto her left side, her ass facing me, and her legs drawn up in just the right position for me to spoon her, which I quickly did. I reached my arm around her and held her titties, and she pushed her body tight back against mine. Within seconds my cock was full size and needed adjusting, so I had to release her titties as I lowered my hand to my cock, slipped it through the slot in my boxers, and placed it against her tight little print panties. She felt so good and warm and the soft fabric of her panties excited me a bit more. I slipped my arm back into position and cupped her titties again. I moved my hips a little and Kim adjusted hers at the same time. My cock was now placed very nicely on her small butt, and I started to make slight pelvic thrusts towards her. When I pushed my cock toward her ass she would push a bit back at me. Then I would draw back a bit and she would relax and pull away as well. My hand was fondling her breasts and she was making soft cooing sounds. We continue our pelvic movements, until it was like I was really fucking her ass, but the little panties acted as a shield. At this point it didn’t matter much to my cock weather she had panties on or not.

I felt her move her arm and could tell that she had just placed her hand on her pussy. I gave a few more thrusts of my cock into her butt crack and felt her buns squeeze my cock each time. This was indeed feeling good. I lowered my hand from her titties to her crotch, and sure enough there was her hand rubbing away at her pussy. I returned my hand to her titties and started playing with them a bit harder. I increased the tempo of my thrusts into her cheeks, and they responded in perfect timing almost like hands, grabbing my cock each time.

Kim spoke and said, “Cum on my panties, cum on me now, please cum on my panties.”

With that and the thought that my cum would be on these little panties for a long time to come, I just started humping like crazy. I wasn’t sure my balls had anything left in them but I was wrong. Kim started cumming herself from the butt fucking and her hand play on her pussy as well as my hands being all over her titties. Again that set off my own climax, and I shot a full load of cum right on the spot that Kim had wanted. As soon as I had cum, I stopped the ass humping. I was tired and getting sore and I knew that there would be a bit more of my sperm seeping out onto her panties right where she wanted it. Kim stopped twitching about the time I stopped humping, and she moved her wet hand up and placed it on top of mine and pressed my hand tight into her titties. We soon fell asleep in that very position and neither of us moved much for the entire night.

I later recalled that I must have had my usual nighttime erections during my REM sleep, and was wondering if Kim’s body had responded in any way. Just one of those things we will never have an answer for.

In the morning I awoke and still had my arm wrapped around Kim, with my hands still on her tits. I moved my hands a bit, like saying are you awake, and her butt pushed back against my morning hard on. I rolled back, then rolled her onto her back, reached down and freed a tit from her bra and put a lip lock on it. My other hand of course was playing with her other tit and having a good old time. After five minutes of tit sucking I had to come up for air.

She smiled at me, and called me her little boy. That shook me a bit but I said nothing. Kim sat up on the side of the bed, and turned and looked at me.

I said, “Would you like for us to shower together?”, remembering my thoughts of hearing her in the shower yesterday afternoon, and wishing I was with her.

She smiled at me again, nodded her head yes, and said, “Yes, but we won’t.”, and with that got up and left the room. My morning hard on was still with me, after the tit sucking, and my cock demanded some attention. I stretched out on my sisters bed, started pulling my joint, and in less than five minutes left another puddle of cum as a present for my kid sister, this one right on her sheet where her pussy would be as she slept. I got up and went to the kitchen and had some hot coffee, while waiting my turn to use the shower.

That afternoon we left the cabin and returned to the city. The next day I had to leave for my new job, in my new car I got as a graduation present. A couple days later, I was unpacking my suitcase, and I noticed the pair of pants Kim had folded and put in my suitcase. It was only then that I remembered that I had put the pair of panties in the pocket. I quickly reached in to see if they were still there, and was happy to find that they were. They smelled a bit strong at this point, and as I examined them I could see that there was still a small wet spot on them. It hadn’t dried since they were balled up and stuck in the pants pocket and no air could get to them. I placed them on the bed, thinking of what I might do with them and continued unpacking. Three layers of clothes below where the pants had been there was a plastic bag. Curious, I opened it and removed the contents. In it were the other pair of panties, and the two bras that Kim had worn during our first sessions of summer school. I blushed. She got me again.
