“Steve, are you thinking about sex with your sister again?”
“I was, Amy. I can’t seem to get her out of my head these days. It is all your fault for planting the idea in my head when were last together.”
“Hmm, we might have to do something about that soon. Would you like to put this nice smooth cock into your little sister’s pussy? Would you like to stroke it in and out until she has an orgasm? Would you like to lick her pussy? Would you do hers as well as you do mine?”
I grabbed Amy’s wrist and took her into my bedroom. Quickly removing her clothes and mine, we got on the bed in a classic 69 position and tongued each other’s genitals.
“Steve, you are quite turned on right now. Close your eyes and pretend I am Sarah and lick your sister’s pussy for me.”
My excitement skyrocketed and soon I was tonguing Amy as if she was Sarah. And Amy was no slouch either as she took my length deep. Soon we were coming together, and I was slurping all the juices spraying from Amy’s pussy as her body tensed and relaxed, over and over.
“Wow, Steve, that was special. Maybe someday, I can get to taste Sarah’s pussy when the three of us make love together.”
After a brief period of rest, we had intercourse twice more before Sarah got home from the library. Amy got out of bed and threw on a robe she kept here for the times she needed modesty in the apartment. I was dozing when she left the bedroom to greet Sarah.

I came home to find the apartment quiet, and a bunch of boxes tucked into the fridge as the leftovers from their meal earlier. Feeling a little hungry, I warmed a couple of eggrolls in the microwave and was eating them when Amy came into the kitchen. She was dressed in her robe which was open slightly. Enough for me to see her cleavage and a flash of her pussy as she walked. Normally, I would have turned away in modesty, but tonight for some reason, I looked at her body and wished it had been me making love with my twin, not her.
We talked about a few things, mostly gossip about mutual friends while I finished the two egg rolls. Amy kept brushing against me as we stood there in the kitchen talking low. I was feeling more turned on by her then I ever had in the past and was wondering what evil was lurking in her mind.
The front of her robe kept parting as the tie loosened. More and more of her body kept being exposed. Her nipples looked aroused, and I could feel my pussy getting moist. At one point, she leaned into me and told me that my twin wanted to go to bed with me. I was certainly not expecting that from her. I looked at her in shock as she kissed me on the cheek and told me she would love to go to bed with me too.
I made some sort of lame excuse and went into my bedroom and shut the door.
This last week had been a real eye opener. I undressed and laid down on the bed. Taking my vibrator out, I ran it over my pussy with thoughts of making love with the two of them. After several small orgasms, the crush of the week got to me, and I fell asleep.
Steve (female)
I awoke Saturday morning with my arm cuddling with Amy in the bed. Last night’s dreams had been quite explicit. For some reason, I ended up in bed with both Amy and Sarah.
I stretched and rubbed my groin against Amy’s backside, but something felt off again. I panicked as I reached for my erection which was no longer there. OMG, I was back to being a woman again. I lay there trying to figure out what to do when Amy rolled closer, and her hand went to reach between my legs. When she didn’t get the expected erection, she opened her eyes and smiled at me.
“It’s about time we ended up in bed together, Sarah. I have been looking forward to this for a long time.”
She promptly brushed her lips against mine. Since I had kissed those lips many times as a guy, I figured that it wouldn’t make any difference as a woman. I kissed her back as she wrapped her arms around me. We rubbed our bodies slowly together as we kissed and nuzzled each other for at least 15 minutes. I could feel my pussy starting to leak and my nipples getting very erect. I ran my hands all over her body as she started kissing down my body, paying attention to all the spots that excited me. My neck, my breasts, my nipples all begged for more.
As a man, I would sometimes be in a rush to get to screwing, but as a woman, I was content to just let things play out. Amy kept kissing down my body, my bellybutton became an erogenous zone as she lightly caressed the lips of my pussy with her fingers. Constantly touching my body with her lips and fingers, I gasped as my pussy was first invaded by two of her fingers. It was almost as if I was a virgin. I knew Sarah was not a virgin but, in my mind, this was the first penetration by anyone other than me.
I ran my hands over her back as her face approached my pussy. I wanted to make her feel excited as well. I captured her left breast in my hand and felt the pebbled skin on her areola. Her nipples seemed to stand up higher then when we played together as male and female. I know Amy, on occasion, had female lovers but obviously this was the first time for me. I nudged her hips over my head, and we settled in a classic 69 position with her on top. I reached down and tweaked her nipples, then slid my hands up her back and gripped her ass. I buried my face in her pussy as I had done countless times before.
I could barely control myself as her lips and tongue started making love to my pussy. I felt the juices leaking copiously as she spread my lower lips with her tongue. I felt the now familiar desire deep in my womb as we licked and sucked on each other’s pussies. As I tongued her clit and pussy back and forth, I could feel the desire building within me. She wrapped her arms around my ass and inserted two fingers in my pussy as she attacked my clitoris with her lips. I was pushed over the edge quickly as my body tensed and relaxed and tensed again with every swipe of her tongue on my clit. The orgasms that followed left me breathless for a few minutes.
I pushed Amy off of me and onto her back. Quickly, I attached my mouth to her nether regions, desperately wanting to bring her the same pleasure I had received. I sucked her clit and flicked it with my tongue as she came for me. I could feel her body tense like mine and soon her juices were spraying my face.
I crept up beside her and we started kissing and caressing each other as we came down from our excitement.
“Wow, Sarah, you lick pussy just like your brother does and he is pretty good at it.”
“Amy, I have a confession to make. And before you panic over what I am about to say, please listen carefully and do not judge. This is going to sound really strange.”
I told Amy about the previous Sunday where Sarah and I ended up in each other’s bodies. I related the whole story of going out to lunch with the parents. Amy chuckled at the embarrassment of the whole ordeal. When I told her about the abrupt switch back on Monday morning, she asked if we knew why this happened.
“Amy, we have no clue, Sarah was researching a paper on animals that can change their sex. Usually lower life forms like worms, etc. But she has no clue as to why we suddenly changed and then changed back.”
“Wait, so Sarah right now has your body?”
“If it happened like last time, then yes she does. and if it is just like last time, we will turn back to ourselves tomorrow morning.”
“Does that mean she can screw me as you but with a female mind?”
“Yes, Amy, although she has not used her newfound penis other than to masturbate.”
“Which do you prefer? making love as a man or a woman?”
“They both have their advantages, although as a woman, my orgasms seem to affect my body and are deeper than one’s I had as a man. They both have their place but the female one’s seem more loving.”
We lay there a while longer, just gossiping and talking about the sudden changes in our lives. I wondered what it would feel like to have a man’s penis penetrate my vagina. And of course, my first thoughts were of my sister making love to me as a male.
Sarah (male)
When I awoke on Saturday morning, I just knew that I had been transformed again. The ache in my cock (I found out later, they called this morning wood) made me hurry to the bathroom to relieve myself. I discovered very quickly that my cock when erect would not allow me to sit on the toilet. I stood up and removed my panties which no longer fit me in order to pee. I was not very good with my aim, and I now knew why men sometimes miss the bowl. It took a few stops (ouch) and starts (ahhh) for the flow to hit the bowl properly. When I was finished, I stood in front of the mirror admiring my cock. It was then I realized that Amy was still here and that she was in bed with Steve (who of course, looked like my female side). I wondered if the two of them had made love this morning. I knew Amy would not hesitate, but I was curious to see how Steve would react.
Sneaking back to my bedroom, I grabbed the only available thing to wear that would fit over my cock, a pair of tap pants that I forced myself into. They fit loosely in the hips, but I had to squeeze my cock into them in order to cover up. Since I didn’t need a bra or a top for that matter, I set off to the kitchen to get the coffee started. As I passed Steve’s bedroom, I could hear the giggles coming from the room. I knew Amy’s voice but when I heard Steve giggle, I was taken aback. We often don’t sound in real life; what we think we sound like in our heads.
I went and got the coffee started and while I was waiting, I started stroking my penis absentmindedly. I was thinking about Amy and Steve laying there together. I did not hear someone come up behind me. Two arms wrapped around my waist from behind and caressed my erection through my panties.
“Hmmm, is someone turned on this morning? How does it feel to wake up with an erection? Is that for me or your brother, whom I might say is a very sexy lady.”
“Amy, you know? Did Steve tell you the whole story about last weekend?”
I turned around and faced a very naked Amy who was smiling from ear to ear. She grabbed my tap pants and yanked them down, freeing my erect cock. Wasting no time, she knelt down and proceeded to inhale my cock in her mouth. I had never felt such bliss as she attempted to deep throat me. I looked down at her breasts swaying as she went up and down on my cock. The sight and feel of her mouth on me brought me to bliss as I shot my semen down her throat. No wonder men love being sucked. The feeling of her sweet mouth on me as I grabbed the back of her head and painted the last of my seed down her throat. It was like I lost control and all I wanted was to come.
