The first time she caught me, she barged into my room while I was lying on my bed jerking off. The door swung open seconds before I reached my climax, after 25 minutes of sensual stroking, alone with my imagination. We locked eyes for a singular, infinite moment as the first spurt of my cum shot up, making a splash landing on my chest. I grunted at the pleasure of cumming and the shock of her walking into my room at the exact moment. Stunned, jaw slack in awe, her eyes moving from mine to my cock and stayed locked onto it as the remaining ropes of hot white sperm flew up, glazing my body. It was only about 30 seconds of mind blowing orgasm, but with her standing in my doorway looking down as my hand remained clamped on my cock, it felt like an eternity.
Soon after, she quickly turned and ran down the hall. I didn’t know if she would call our mother and tell on me, or if I should call her first to claim the trauma of her intrusion to bring the damage control down to a minimum. It’s not that I didn’t enjoy it though, as twisted as that sounds. My own twin sister, the one I spent all these years growing up with, right from utero, catching me cock in hand. It was something I never thought of. Not even step sibling porn would peak my interest, but this? I haven’t cummed so fucking hard all by myself like that in a very long time… If ever.
I got up and ran down the hall, following her into her bedroom.
She turned away from me as I ran into the room, her baggy tee spun and jean shorts exposed a booty I had never thought to look at before now. I stepped close, grabbed her wrist, and turned her back around. Her eye glanced down at my still erect girth, then quickly up to the ceiling fan. My eyes wide with concern and a little fear of the repercussions of what just unfolded. She looked scared and afraid of what I might do to her. So I let go of her wrist, stepped back, and said “we can’t tell anyone about this. It’s a bad idea for you.”
Appauld, she replied, “what do you mean ‘for me’?! You’re the one who came to your own sister!”
“My door was shut, you didn’t knock,” I retorted. I stepped closer in towards her, standing tall and locking eyes with hers in intimidation. My voice slight lowered and in a firm tone, “and you just stood there and fucking watched your twin brother cum, without a second thought.”
I walked out of the room. Standing bare assed at the closet across the hall from her, I grabbed a towel and swung my dick to the left, and down the hall to shower off.
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 she would make eye contact briefly before looking away from me. I guess we were acting pretty similar to when we did fight.
The next time I jerked off though, I could hardly think of anything other than us looking into each other’s eyes as I had cum the last time….and how fucking hot she looked in that t-shirt. My sister was shorter than me and had a nice body… Perky, round tits but not ‘big’. Over the summer, she would lay out in the sun a lot, so she had a nice tan lines 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 couldn’t NOT have a sexual thought about her.
We had been taught, growing up, to respect the privacy of others… Knocking on doors was something that we always did. I started to notice, though, that she stopped 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 again… that I was stuck in her thoughts the way she had become stuck in mine.
I didn’t know quite what to do about this. We were still just teenagers, so there wasn’t any manuals or rule books, blogs or posts to dictate what the next move was. I had no idea if other people had these kinds of thing happen or not. We were in several classes together in high school, so I wasn’t about to talk to any of our friends about it.
One night I was walking back to my room and while 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, and her, a reddish glow. She was lying on her back with her covers all messed up. Her knees were up in the air, her legs spread, and her hand between her legs. My cock instantly pressed itself against the drywall. I couldn’t take my eyes off of the they way her legs twitched, and the patch of hair between her legs while her fingers disappearing inside of her pussy. I reached into my pajama pants, pulled my dick out, and started jerking off. I could hear an occasional whimper or moan from her and the slight sound of her wetness. I came so fucking fast from all this. The risk of her catching me, the sounds of her aching loins errupting up through there lungs, and of course, that fact that she was my teenage sister. I wasn’t prepared for this intensity, so when I busted, my cum shotstraight out and landed on her door. As I was cumming, my hand jerked right and bumped her door frame. 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. Now she could tell on me and it WOULD be a good idea….
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 because of the bright pinkness 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.
She sat down on my bed, leaned against the peak of my footboard, and spread her legs open, one after another. Her eyes paced back and forth from mine, to the way I stroked my shaft as I leaned back against stage headboard. The 2 of us, restricting our moans even in the empty house, masturbating with the intuition only twins can have. She rubbed her clit faster and my wrist gained momentum. My strokes become longer, reaching from balls to tip, and her fingers went deeper into her tight, fresh little hole. It was as if an omniscient being was directing us in perfect synchronization. The longer we masturbated with our twin, it felt more and more like a religious experience. Spiritually connected in how we played with ourselves, and in turn, each other. Our moaning and grunting was becoming it’s own language. The energy in the room could fuel the whole neighbourhood with how intense my beautiful sister and I were with one another.
Our orgasms came up on us 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 on her thighs and her pubic hair. To this day, it remains in my mind as one of the most elevated, erotic things that I have ever seen or done. My cum on my sister’s sweaty pussy 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 alive and activated for the first time in our lives. It felt as though a fire was lit between us that night that has never been extinguished.
I know for me, I never forgot how to connect with that level of emotional and spiritual intimacy again, and I would say she never did either. Everytime were around eachother, there’s a certain… Heat… Elevated emotional experience that we both receive, just by being near the other twin. And people will chock it up to that, of being a twin. But her and I will both know for as long as we live, that it’s because she barged into my room that one day, and watched her twin brother lock eyes with her, having their first orgasmic experience together.
