My twin sister and me

The first time she caught me, she walked into my room while I was lying on my bed jerking off. She opened the door just before the moment that I came. We locked eyes for just a second…we were looking each other in the eyes as the first spurt of my cum shot up before landing on my stomach. I grunted at the pleasure of cumming and the shock of her walking into my room at the exact moment. Her mouth opened in shock, her eyes went to my cock and stayed locked onto it as the remaining shots flew up before resting on my body. We were both in shock. My hand was clamped on my cock after my orgasm, making it red and engorged. She turned and ran down the hall. I didn’t know if she was going to call my mom and tell on me or what so I got up and ran down the hall, following her into her room.

She was wearing the oversized t-shirt that she slept in and she was facing away from me as I ran into the room and grabbed her wrist to turn her around. Again, her eyes went right to my cock and her mouth hung open. I began to beg her not to tell mom. She finally took her eyes off of me and looked at me and quietly said okay.

Things were pretty strained between us for the next week. My mom kept asking us if we had fought because we were acting the same way we usually did after a fight. We didn’t talk much and we would make eye contact briefly before looking away from each other. I guess we were acting pretty similar to when we did fight.

The next time I jerked off, I could hardly think of anything other than us looking into each other’s eyes as I had cum the last time….and how sexy she looked in that t-shirt. My sister was shorter than me and had a nice body…nice round tits but not ‘big’. She laid out in the sun a lot, so she had a good tan and long brown hair just past her shoulders. I had never, in my life, had a sexual thought about her but ever since she walked in on me, I could hardly NOT have a sexual thought about her.

We had been taught, growing up, to respect the privacy of others…so knocking on doors was something that we always did. I started to notice, though, that she never knocked on my door when she came into my room anymore. Very often I would be at my desk doing homework but every time she came in, I noticed she would always look straight to the bed. I began to imagine that she wanted to see my cock…that I was stuck in her thoughts the way she had been stuck in mine.

I didn’t know quite what to do about this. We were teenagers in the 80’s, so there were a lot fewer sources of similar things to read about. I had no idea if other people had these kinds of thoughts or not. We were in several classes together in high school at the same time so I wasn’t about to talk to anyone at school about it.

One night I was walking back to my room and in passing her door, I heard her moan. I stopped and noticed that the door to her room wasn’t closed all of the way. I stood listening and there was no doubt about what she was doing. I peeked through the crack in her door and was amazed at what I saw. Her room was lit only by the lava lamp on her night table, which gave her bed a reddish glow. She was lying on her bed with her covers all messed up. Her knees were raised, her legs spread, and her hand between her legs.

My cock instantly hardened. I couldn’t take my eyes off of the damp patch of hair between her legs and her fingers disappearing inside of her pussy. I unbuttoned the button on my pajama pants and started jerking off. I could hear an occasional whimper or moan from her and could hear the sound of her wetness. I came so fast and my cum landed on her door. As I was cumming, my hand slid off of my cock and bumped her door. It sounded like dropping an anvil in the quiet of the hallway. I saw her starting to close her legs and I ran to my room, shutting the door behind me. I jumped in the bed and lay there heart pounding, hoping somehow she didn’t know it was me.

Not ten seconds later, I heard the door open and then close. I thought maybe I had fooled her and she thought that I was asleep…I couldn’t believe my luck. I turned over away from the wall and my cock, which was still hard and hanging out of the opening of my pajama pants swung over so that when I was on my back, pushed up on my elbows, it was standing straight up. I then noticed that I had not fooled my sister and she was standing inside my room with the door closed behind her. I saw her eyes locked onto my cock again and it inadvertently throbbed. Her eyes widened and she took a step towards my bed. Thoughts were racing through my mind and I didn’t know what to say or do. She sat down on the opposite end of my bed, sitting up straight with her back against the footboard. She held her hand out and on two of her fingers I saw, in horror, my cum. She had seen it on her door and now she knew what a degenerate that I was. Not only did she know that I jerked off but now she knew that I had jerked off TO HER.

I started stammering and apologizing but all she said was “shh” and, as she did, she raised her fingers to her mouth to accompany her “shh.” Her tongue slid between her lips and licked my cum off of her fingers. She then reached down and pulled her nightshirt up and my cock throbbed again at seeing her pussy. One of her hands held her shirt up, just showing off the bottom of her tits and her other hand slid down her belly and between her legs. Her dark pubic hair looked even darker than the bright pink of her pussy as she spread her lips in front of me. She still hadn’t said a word and I didn’t know what to say, either. Her eyes went to my cock and then she looked at me eagerly to join her. There was little left of my brain that had not exploded at this point and my sexual desire overrode any thought of what was right or wrong. My hand went to my cock and I started stroking.

The first woman that ever saw nude was my sister. The first woman that ever saw my cock was my sister. I can’t explain how close and at one I felt with her. My eyes washed over her body…memorizing every single bump on her areola as she had lifted her shirt higher, her other hand rubbing over her nipples. I did enjoy looking at her pussy and her tits but most of the time, we were looking into each other’s eyes. Our orgasms came quickly and when I came I instinctively pushed down on my cock so that the head was pointing towards her. My cum shot out and some landed in her pubic hair and it remains, to this day, one of the most amazingly sexy things that I have ever seen. My cum in my sister’s sweaty pubic hair just an inch from her fingers inside the tight grip of her puffy pink pussy lips. Our moans from our shared separate orgasms in our ears…our bodies were so on fire. A fire was lit between us that night that has never been extinguished.

This is the first story of my twin and me that I have shared. I hope that you enjoyed it. I invite and would appreciate any comments that you have, whether in the comments section or by DM. If you’d like more, please give the story an upvote and tell me. I have much more to write about, as the trajectory of our lives was forever altered in that first week so many years ago.
