Twinning is winning - Part 1

An 18 year old boy is lusting over his twin sister. When he finds her playing with herself, he decides to take what is his

Soft skin. Round tits with hard nipples. A slim waist and wide hips. And then her small pussy, hidden between her thighs. She didn’t know I was watching her through the keyhole of our shared bathroom. My sister dried herself off slowly as she watched herself in the mirror. Her tits jiggled and bounced as she moved the towel over her body. My throat dried when she placed her foot on the edge of the bath to dry her legs, and I could only imagine how her pussy would open just a bit. The angle wasn’t right, but I did see the glorious curve of her round ass. I knew what I was doing, as my hand moved to my hard dick. I was completely and fully aware of the fact that I was eyeing my 18 year old twin sister. She accidentally dropped her towel and I licked my lips as I watched her bend down at the waist, her ass towards the door. To me. I watched how her round ass cheeks opened slightly, her tight pussy visible through her legs. Oh, if I could only ram my dick inside that pussy, pump her full of my cum. The moment only lasted a second or two, but it was imprinted in my brain. She dropped her towel in the hamper and walked away to her own room. By then, I had already released my load into my boxers.

Our parents weren’t home, like most weekends. So I opened the door to the shared bathroom and grabbed her dirty towel from the hamper. I knew she always used one of the corners to dry off her pussy, and it didn’t take me long to find the one she had used. It glistened in the light from her juices. With my eyes closed, I slowly breathed in her scent. If she knew I was doing this, she would have me committed. For sure. But I didn’t care. My attention was pulled away from the used towel by a stifled moan. Quickly I moved back to my room and put on some music. Loud enough for her to hear it in the background, but not so that she could complain. It would be perfect. She would think I was occupied, giving her more freedom to do what she wanted to do.

I tiptoed back to the bathroom, a small smirk on my face. The door to her room was slightly ajar, and with my fingertip, I pushed it open just a tiny bit more. Through the slit I saw what I was hoping to see. My sister, on her back on the bed. Her body moved gently, following the rhythm of her fingers between her spread open legs. She moved slowly, but deliberately. It looked like she wanted to take her time, as she gently rubbed her clit. She sighed away another moan and widened her legs a little more. My cock hardened once again and I adjusted it a little, giving myself a bit more space in my boxers. My eyes were trained on her tits, which moved with her deep breathing. Her fingers, which explored her most intimate places. But mostly, I was staring at her wide open pussy. At her juices that glistened in the dim light. With her fingers, she spread open her little hole a bit, but she didn’t dip in yet. She was teasing herself. Without realizing, I had pushed the door open just a bit more, so I could get a better view. What I would give to dive right in there. Between her legs. Lick every bit of her glorious folds, taste her juices and prepare her for my rock hard cock. Opening her up further to accommodate my girth.

And then I heard it. A deeper moan, which sounded suspiciously like my name. I stilled, once again adjusting my cock in my boxers. Did I hear that right? Her fingers dipped in her pussy and her back arched off the bed. The perfect picture of porn. She moaned at the same time, and this time, I knew it for sure. She wasn’t moaning my name, but I could easily think she was. Riding the surge of confidence, or maybe stupidity, I pushed the door further open and walked towards her, dropping my boxers on the ground. She didn’t know I was here until she felt the bed dip under my weight.
“W-what are you doing here?” she gasped, quickly closing her legs. I just smiled.
“I heard my name,” I answered in a soft voice. Her eyes flickered towards my raging boner and I could see the fear in her eyes. I knew she never had sex before. Which I didn’t understand, because she was drop dead gorgeous. And who better to take her virtue than someone who actually cared for her well being?
“I- I wasn’t... Please, leave.” She sounded scared.
I placed my hands on her knees and pushed them wide again. I could feel her muscles strain as she pushed back, trying to keep them closed.
“Please, don’t,” she whispered, but I didn’t listen. I pushed harder, my eyes aimed at her pussy. She used her hands to try and push me away, but all I could focus on was pressing her legs wide. When her legs were open just wide enough for me to reach, I moved down quickly and let my tongue slide from her pussy hole up to her clit. I could feel the shiver run through her body and all the fight left her. Her legs immediately relaxed and fell right open for me. She groaned deeply as I feasted on her delicious tight pussy. She tasted absolutely divine. My tongue caressed her clit and slowly moved lower, lapping up the juices that leaked through her pussy lips. With my tongue, I opened her further up, and my tongue dipped inside. Her whole body shivered when I did that. So I did it again. She was already completely soaked, and she was ready for me.

I shifted to my knees, which she barely noticed as I kept nibbling on her little clit. My heart was pounding, but my brain was focused on just one thing. Burying my cock deep inside my sister's cunt.
“Please,” she whispered again, between the moans. “Please go. You can’t. Oh God.” I moved up at that point, hovering over her soft body. The tip of my cock rested against her delicious hot pussy. I watched how her eyes widened as she stared at me, barely grasping what was about to happen. Suddenly she started fighting, pushing me away, slapping me in my face. My cock just hardened at the stinking pain and I smirked.
“You can’t. Stop, I’m a virgin! I’m telling dad. Please, stop!” I lowered my body onto hers, my cock now nestling snugly between her legs. I did feel how she was trying to close her legs. How she tried to get her knees under my body, so she could kick me away. Her nails dug in my skin. She was absolutely panicking, but adrenaline pushed me forward. My ears were ringing and my cock twitched. I didn’t say a word as I moved my hand down. I grabbed my cock and guided it to the entrance of her pussy. She really started to beg now, thrashing under my body. But I was stronger. Much stronger. Staring right at her panicking eyes, I let the tip of my cock slip inside her wet folds.
“No, no, no, no, no,” she screamed, but I pushed on. Guided by her earlier arousal, I pushed on. It was hard, her fighting made her super tight, but I pushed. Hard. Until I suddenly slipped in completely, my hips pressed against hers.
“Aaah, no,” she sobbed. I felt how the fight in her weakened, now that she had lost. She kept pushing me away, but I didn’t move. I just thrived in the position I was in. Buried deep inside my twin sister’s delicious hot, tight little virgin pussy. Where I belonged.

She had stopped fighting at this point. Her arms and legs fell limp on the bed. Staring right at her face, I started moving. Slowly I pulled out, only to drive back in again. I watched how her face twisted in pain the first few times. She then just winced as I slammed in. And then I heard it. Her breath caught when I shifted a little, right before I moved back in. She felt it. The first tinge of pleasure. She would never tell me, but she felt it. I moved my arms under her knees, widening her legs and folding her in half. With her hips elevated in the air, I grinded deep inside her. Right now, she couldn’t hold back a moan. I knew better than to mention it. She had been through a lot, and adding humiliation to that would break her. Believe it or not, I still cared deeply for her. I wanted her to feel good. Just as good as I was feeling right now.

I was glad I had an earlier orgasm, meaning I could go much longer. I kept moving in and out of her, salivating over the feeling of her pussy gripping me on the way out, and welcoming me right back in. Now that she had gotten used to my girth and length, I could move a little faster. A little deeper. I knew she was loving the feeling right now, even if shame still washed through her. She knew it was wrong. It WAS wrong, but that didn’t mean we couldn’t both enjoy what we were doing. I placed one hand on her round tit and gently rolled her nipple between my fingers. Her back arched slightly, and she moaned louder. I wanted her to come. I wanted her to feel the intoxicating bliss from having my cock inside her pussy as she orgasmed. I moved faster, my hips slapping against her hips. Where her hands had scratched and slapped me earlier, she was now grasping my arms, her fingers digging in my skin as pleasure started to build inside her. She was close. I was too, but she had to come first. I let go of her nipple, and instead moved my hand between our bodies, finding her clit easily. With just a few quick flicks, I felt her whole body tighten. Her pussy muscles clamped tightly around my cock and she moaned loud, almost screaming as pleasure swept her away. I slowed, but kept moving, prolonging her orgasm for as long as I could. When she finally relaxed, I shifted again. My turn. In quick, short movements, I hammered inside her, feeling tension build in my balls, aching for a release. So close.

“Stop,” she suddenly whispered hoarsely. I looked at her questioningly. “Don’t come inside me, please. I’m not on the pill.” I knew she wasn’t, but it was too late now. I couldn’t stop. I exploded hard, sending thick ropes of my seed inside her fertile womb, groaning loudly.
“Fuck,” I whispered, as I poured everything I had inside her small body. I didn’t pull out until I was completely done twitching, and my cock started to soften. Slowly I pulled out and let myself fall next to her on the bed. She just laid there, her legs still wide open, panting.
“I’m sorry,” I started, once my breathing slowed. “I didn’t mean to come inside you. It was too late. I couldn’t…” I stopped talking, staring at the ceiling. She could be pregnant right now. If I wanted to do this again, I needed to be safe. Still, the thought of my seed inside her pussy made my cock twitch. That is, if it wasn’t so worn out already.
“And you’re not sorry for fucking me?” she asked in a sharp tone, her hands slowly moving down to her spread open pussy. My seed slowly started to leak out. “Not sorry for taking my virginity?” I shifted to my side to look at her. Was I sorry? I was driven by lust when I took her. Still, I didn’t feel sorry for fucking her like that. I didn’t feel sorry for taking her virginity. I was sorry that I ignored her pleas, and that I forced myself on her. Would I do it again? Absolutely.

So I told her the truth. About how I had lusted after her for ages. How I loved watching the shapes of her body, the curves of her ass, the roundness of her boobs. How I had dreamed of burying my cock inside her pussy, and how much better the real deal was. I told her I was sorry for raping her like that, but that I wasn’t sorry for taking her virginity. I loved her, but it wasn’t like I was in love with her. I just wanted her body. The fact that she was my twin, my own blood, the taboo, that was a huge fantasy of mine. And somehow, she understood. She nodded. She didn’t judge. And in the end, she just smiled.

“Well, considering I would most likely lose my virginity to some loser once I move to college, I am glad you took my cherry. I’m glad my first time was with you. But next time, ask, okay? You can’t go around and rape girls like that.” Next time? Hope fluttered in my body. I just nodded and smiled at her.

The conversation flowed easily after that. It felt like a heavy weight had been lifted between us, and we were closer than ever. With our legs tangled, like we used to lie when we were younger, we chatted until deep in the night. We didn’t care that we were both naked. We shared every thought, every joke, every insecurity we had. The bond between us had declined over the years, being teenagers and all, and we had so much to catch up on. Suddenly, I saw her cheeks flush red.
“What is it?” I asked, worried. Her flush deepened.
“I have two requests. One for now, one for later.” I sat up a little, looking at her, not saying a thing. She took a deep breath and decided to blurt it out.
“Can you fuck me from behind? I’ve always wanted to do that. Not… not my ass. Not yet. But just, from behind?” Immediately my cock twitched again and I chuckled.
“And the one for later?” The flush now spread over almost her whole body, and she looked away. Still, her voice was steady and confident as she spoke.
“I want you to rape me again at a different time. Don’t tell me when. Just come in, pin me down, fuck me senseless and then walk away. Just, wear a condom next time, okay?” I laughed, flipped her over to her knees and slammed my raging boner right in her pussy without saying a word. There was still plenty of cum inside her to slip in easily. Adding another load to that won’t make a difference for now. She won’t get more or less pregnant from it.

Her back hollowed and she pushed herself back against my rough thrusts. Like a true whore, she moaned deeply. My hands dug in her hips to pull her into my thrusts. I curled one arm around her chest, grabbing her tit and pulling on her nipple harshly. It was a test, seeing if she could handle it, but all she did was moan louder, widening her legs more and taking me in deeper. With a wide grin I looked down. At the pussy that ate my cock so hungrily. At the small, puckering asshole that I will claim as mine soon and the body of my own twin sister twitching on my dick. I let a thick glob of spit fall on her asshole, watching it slip over her hole before adding to the juices on my cock, slipping in her pussy. God, she was perfect. Another thick glob of saliva fell on her asshole.
I couldn’t wait to open her right up.
