so this was all kind of out of no where and bizarre . but so basically some background about me and my sister. she's 3 years younger than me so i'm a junior in college right now and she's freshman. and so we've always been very close and got closer as we grew up. but this one night everything got crazy. i've never really had any sexual moments with my sister up until this night other than seeing her naked once without her knowing and one other time when i was changing in the morning and she saw my erect cock and her face was like 😟. i think she thought it was big but i thought it was weird at the time. i never really wanted to fuck her or anything but as she got older she got way hotter. her tits started blossoming and getting extremely perky. she started wearing makeup and working out so everything she'd come home it would be in some skimpy gym clothes. and so this is where i started feeling a sexual attraction to her. i started jacking off to her instagram pictures to start it off. i ended up being in a dying need to fuck her, but i knew it wouldn't happen. So this is where the story really begins. One night i'm at the bar with her and her friends, she was wearing the sluttiest shit ever and was butt fuck drunk. after a hour or so at the bar i couldn't find her and then i looked down the hallway from where the bathroom is and i saw some guy grabbing her tits while making out with her. i was a little distant and she didn't see so i watched for a little bit. i could hear her quiet moans and her tits getting groped and pressed. i've never been a cuck but this was soooo hot. before i knew it i started getting hard as fuck and my drunk ass decided to keep watching. and before i could look away we make eye contact and my face was literally 😦. she got kind of spooked out and then pulled away from the guy, and i also got scared so i scrammed away. we didn't talk about it for the rest of the night, but it was time to go home and she couldn't even make it to the uber car so i had to give her a piggy back ride. i could feel her tits pressed on my back and her legs wrapped around my body with her foot dangling on my cock. after we got home i put her in bed (we shared a bed because she was staying at my place instead of her dorm). then i got shirtless and out of no where she started drunkenly saying ooooo mr muscles and shit like that. and i was like stfu u dumb bitch and i tackled her and jokingly choked her. when i had my hands around her neck she made a joking moan and we both cracked up about it, then i got off her and layed down and she started cuddling me and i got super nervous. and then i put my hand on her waist. as she was resting her head on my chest she could slowly see my cock getting erect and i know she noticed because in the next couple seconds she lifted her leg over me with her thigh on my cock. i was so shocked and did not know if she felt it or not. and then i had to do this now or never it was the chance. i started pulsing my cock and she definitely noticed because she slowly whispered and chuckled to me "are you hard". and i go ahhhhhhh maybe😬. then she said "i wanna see". then proceeded to pull my pants down while still cuddling me and said "wtf it grew since the last time i saw it" and i was in such shock i didn't even say anything i became mute. it was like a porno in real life. then she put her cold small precious hand on my warm veiny cock and started playing with it. she would tickle the tip of it and see my body squirm and would giggle. i then started getting more comfortable so i put my hand on her ass and she laughed and said ooooo bad brother. and at that point, that sentence, completely turned me on. she got on top of me and we started making out with her silk pajamas thrusting on my cock and balls. i never thought my sisters pussy would be getting wet on my cock. i stopped her for a second and said i've always wanted to fuck you. she said todays your lucky day and sits up on top of me and takes her shirt off and i was shocked she wasn't even wearing a bra. her tits dropped and dangled from side to side. i placed my finger on my sisters nipples and gasped while she was sitting on my rock hard cock. she then took my pants off and slid my cock inside her then she started kissing me with her breasts on my chest and her pussy on my cock. we then fucked for hours and went to bed. after that we woke up and fucked againnnnnnn. we haven't talked about it til this day, it's been about a month. but i want to do it again.
