I was 14 when it happened, my sister was 16. I was the summer before my 9th grade year, I spent lots of time working out as the coach had seen me in 8th grade and wanted me to go strait on the varsity foot ball team I was big for my age, already over 6 feet tall and built like a stone wall. My sister even though she was older, was much smaller than me and was very sexy. I often caught my self thinking about her and getting a hard on. It was a saturday when it happened, I came home from working out with some guys on the team at the YMCA and she was there alone. Mom and dad grounded her cause she got mad about something and called mom a bitch. I came in and asked her what was wrong and she slammed the door in my face and told me to leave her alone.
“I’m just worried about you.”
“What ever, no one cares about me, mom and dad hate me, and your just like all the other guys at school all you want to do is to fuck me. You think I’m blind, I see the way you stare at me sometimes. Your my brother you know, but I can tell what your thinking.”
“If that’s all I wanted, I would have done took it by now.” I replied in anger, but also wondering if she really noticed or was just shouting things.
“What the fuck ever, you couldn’t take it from a free whore. Your may be all big and bad but your just a scared momas boy.”
“You may wish you hadn’t said that.”
“Why, prove me wrong if your so tough. Come and try to rape me, mama’s little prick.”
That comment was the last straw, I locked the main door I’d just came in and turned and ran into her room. Mom had dad take the lock off her door cause they wanted to be able to get in there anytime with out her locking them out. She jumped up and started to run but I grabbed her and slammed her down on the bed and after a few minutes had her hands pined above her head. With my free hand I pushed her shirt and bra up and started sucking her breast, when she seen she couldn’t over power me she stopped fighting and strangely after a few minutes seemed less and less upset.I kept on sucking her breast for about ten more minutes. When I pushed her skirt up and pulled her panties down, I still had her hands pined but she didn’t try to kick and stop me. I slowly moved myself between her legs and pulled my cock out and slowly stuck it in her pussy. I heard her let out a squeal when I penetrated her as I was rather big for my age in that respect also. I then rearranged how I was holding her so I was holding each of her wrist in each hand as I started humping her. She looked away as she squealed each time I rammed into her. I started getting faster and faster, I enjoyed the feel of her pussy. I could tell part of her enjoyed what I was doing as after a few minutes she started really getting wet, and her squeals of pain had turned into moans of pleasure. After about 45 minutes to a hour I started feeling it in my balls and before I know it I’d shot a load of cum into her. After that I slowly raised up and sat at the end of her bed as she laid there.
“Still think I couldn’t have took it.” I said with a smirk on my face.
She raised up and looked me in the eyes. “I’m sorry, I shouldn’t have slammed the door or yelled at you. I’m not mad at you I know you forced me to do that but I can’t help it when a guy sucks my breast that makes me so horny, no matter how mad I am, by the time you got in between my legs I was wanting it worse than you,but didn’t want it to show, and you are so much better than my BF ever was, wow that was great.”
“Oh, so you gonna tell mom and dad or anyone.”
“Hell no, just as long as you promise me one thing.”
“What’s that?” I replied wondering what she was about to say.
“I want us to have sex more often, I’m not gonna dump my BF that way if anything happens I can just do it with him a few times and blame him.”
“OK, sounds good”
After that we hugged and shared a deep kiss and I went back out of her room. We had sex at least once a week if not twice after that. Any day that me and her were there alone, and we still do when ever we see each other and her husband is not around.
