Emboldened by a lack of protest I slipped my hand under the top then paused when my fingers pressed on the underside of a breast. She still was quiet so acting with hormone driven courage I cupped the breast lightly. The mound filled my palm and as my fingertips moved over her skin I felt her nipple stiffen. Oh my gaud! She reacted to my feeling her up and it wasn’t a protest……..! Encouraged by the reaction I pressed my luck and pressed her tit even more. I could feel my own pulse in my neck while I felt Shelby up. I quickly succumbed to temptation and got more active by stretching my fingers to caress the other nipple. It took no time at all to be paying attention to both breasts. When I felt both nipples standing tall I knew I couldn’t stop until I seduced her, asleep or not.

I played with Shelby’s tits for a couple of minutes then took another breath of courage and eased closer to her. When my erection touched her ass I shifted until it was lodged in the length of her butt crack. I bumped my hips giving myself a thrill then moved my adventurous hand from under her shirt to the flat of her stomach. The skin under my fingers was growing warm, the temperature in the air around the bed was increasing as I heated up even more. I pulled my hand to her hip then tugged gently, to get her even closer. Her back bent slightly and the pressure of her butt against my cock increased, I bumped again, rubbing it on her. My hand eased over her hip, down her pelvis until I was touching the top of her cunt through her panties. When I stroked her sex with my fingertips her body jerked lightly and her legs moved far enough apart I could put my hand over her cunt.

I don’t know if she was asleep when I got onto the bed but I sensed she was awake as I caressed her slit. She began to move in sync to the feel of my hand, her head rolled back stretching her neck then Shelby reached behind her, between us, and gripped my erection. As I rubbed her through the thin material of her panties she began to stroke my cock. Even as warm as I was, I felt my sister heating up.

We lay like that for a few minutes, she squeezing and pumping my erection through my boxers while I played with her pussy. When she moved her hand then slipped her fingers under the waistband of my shorts I did the same for her. As she contacted my erection directly I slid two fingers over the soft fleshy lips of her pussy the bent a finger into her. For several minutes she and I did nothing more than use our hands to raise our levels of lust. She was smearing the bubbles of pre-cum over the length of my cock as I was pressing on the hood that hid her clit. When I touched her there it stiffened like a miniature hard-on and she whimpered a soft sound of pleasure. I concentrated of turning Shelby on and she responded by undulating her back, rolling her ass against me. It took maybe three more minutes until she froze solid for a moment then gasped a deep breath and quivered in silence. When she climaxed she gripped my cock so hard she left fingernail indents. It was an awesome feeling.

She turned her head to look at me with wide inviting eyes and the hint of a smile on her lips, I pulled on her shoulder so she rolled over to face me. She put a hand on my cheek and caressed my face then kissed me. The kiss was gentle, soft, and full of permission which caused an explosion of need in my balls. I wrapped her up in my arms and pulled her into a full body hug. She and I lay quiet like that until I bumped her groin with the erection trapped between us. She kicked the sheet off completely then sat up to pull my shorts off. When I was nude Shelby again held my cock but this time she was exploring it with her eyes as well as her hands. Since she was sitting next to me I took the opportunity to pull her shirt off. After I tossed it to the floor I pushed her back to the mattress then took her panties down her legs and dropped them to join the top. I moved around until her breasts were within reach of my mouth then began to kiss, lick and suckle her tits. She relaxed back on the bed again and let me seduce her.

Seducing my sister may have been one of the most intoxicating things I had ever done in my twenty-one years. She was soft, sexy, pliable and the fragrance of her fresh from the shower only heightened my desire. As I felt, caressed, massaged and fondled Shelby she was getting more feral. She was moving fluidly, sipping short gasps of air as I worked on her from face to ankles. After several long minutes of turning my sister on I stretched lengthwise between her legs then paid attention to the focus of my desire. She hadn’t shaven all of her hair, she had neatly trimmed the edges and thinned the mat. I put my nose in her pubic hair and inhaled the scent of her musk mixed with perfumed powder, I kissed her cunt while fucking the bed. I nuzzled her thighs, licked the crack from anus to clit then turned my tongue loose on her. I lapped Shelby and she got even more limber, taking quick sharp breaths while rolling her nipples in her own fingers. She lifted her legs, wrapped them over my back so my head was trapped between her warm smooth thighs, she wasn’t going to let me go until she climaxed again. I managed to get a hand under her ass and caress her anus with my middle finger. Shelby arched off the bed and she began to quake. Her legs were shaking, her arms shot out to each side then she slapped the bed when I jammed a finger in her butt. She never made a sound louder than a soft wheeze. When she stopped moving I pushed up and her legs slid boneless off my back.

I got to my knees between her wide spread legs then took her hips and pulled her close enough I could put my erection in her. She reached for me then held it in place while I pressed forward. Her orgasmic juices were flowing so Shelby’s hot wet cunt welcomed me with no resistance, no friction. I pushed into her until our pelvic bones meshed, Shelby lifted her arms, put her hands on my chest and looked into my eyes as I began to fuck her slowly. We coupled in that position for a few minutes then I pulled away and laid behind her. She lifted her leg to give me access then I entered her again. Spooned against her like that freed my hands to feel her body and tits. I fondled Shelby as we fucked gently, our hips were rolling with a relaxed rhythm, my erection sliding, not slamming in her. The slow easy pace only heightened the pleasure of sex. She was purring; each time my balls pressed against her pussy she rolled her back, like a cat enjoying the stoke of a hand. She reached over my head and pulled it down until my lips were on her neck. I licked her skin then started kissing the nape of her neck which caused her to shiver against me. I worked my mouth to her face then she turned to me as far as she could and we started making out, our tongues quickly joined the ritual. She rolled to her back and lifted her near leg so I had more room to fuck her and we could neck without stretching. My hand went to her breast, my tongue explored her mouth and my cock pressed even deeper.

Shelby broke the kiss then said the first thing since I got on the bed with her, “Cum.”

It was magic. Just that one word uttered as a whisper caused my cock to clench and my body to jerk. I held back just long enough to see her eyes roll up and take a long deep breath. Shelby started vibrating from feet to head as the end of my erection shredded and I surged into her repeatedly. She went stiff as a board, arched her back and emptied her lungs in a rush of soundless air. Again she had a totally silent orgasm.

We rested for a few moments, bonded by my relaxed prick in her cunt. She pulled off, rolled away from me then cradled a pillow. I went to my back and enjoyed the afterglow of good sex as we drifted to sleep.

I woke up slowly to the sensation of another growing erection. As I came more awake I became aware of a hand caressing my thigh, and it wasn’t my hand. I turned to see Shelby on her side facing me, she was smiling as she moved her hand to my nuts. She didn’t say anything, she didn’t need to. In seconds she had what she wanted, my cock stiffened rapidly and she shifted her fingers from my balls to my erection. When I was man enough for her she crawled over my lap, guided my cock to her cunt then started rolling her hips. I glanced at the bedside clock and saw that it was 3:04 AM. She fucked me with more energy than the first time but it was still a totally silent affair. We shifted around, screwing with the passion of new lovers until she lay with her face on a pillow, on her knees, her ass high in the air. The orgasm building in her womb burst like a pricked balloon. Her cunt flooded with her cum which sent the message to my balls, I came into Shelby as she quivered in silence. My cock fell from her when I leaned back and her pussy started oozing semen. She cupped her cunt, looked at the mess on her fingers, relaxed back to the bed, wiped her hand on the sheet then closed her eyes. We were done and she was ready to sleep again.

I was first up that morning and had two cups of bitter hotel coffee ready when she roused. She got off the bed and I saw her complete nudity in full light. My cock stirred as she stretched then mumbled “Morning.” I thought she might say something about what we’d done but without comment she went to pee and clean up. 30 minutes later we were back on the road to the family reunion. By some mutual, unspoken agreement we didn’t talk about what we did, we didn’t’ reminisce, make excuses or confess our feelings. It was as if we had spent the night alone, in the two beds. Three days later we stopped at the same hotel, got the suite we reserved then spent the night in separate bedrooms. I was kind of hoping she would come to me but she didn’t and we didn’t. We were lovers that one night, no more.

Eleven weeks after our trip she came to my dorm room, she was graduating the next day so her room was empty and she was hanging with me until our parents showed up. It had been a long day and she was tired so Shelby came to lay on my bed with me. She napped on a pillow for about an hour then woke up. She picked up her head, put her lips next to my ear and said softly, “We should have been more careful, I’m pregnant.”
