Straight Male / 35
About 22 years ago, when I was around 13, we still lived in a two bedroom house and my sister, Nina, then 15, and I shared the same bedroom. On some weekends Uncle Mike, mom's older brother, stayed with us Saturday nights, sleeping downstairs on the couch. I clearly recall Uncle Mike sneaking into the room to Nina's bed. She would either be on her stomach or turn to be on it and put her pillow under her hips moving her fanny up for his better access. I had no idea how or when this all began. In the room, lit only by moonlight and/or street lamps outside, Uncle Mike slid his long cock into Nina and quietly fucked her. Once in a while she would moan and/or whisper something to him. I seem to recall her almost inaudibly, saying, "oooohhhh, good, good, Uncle Mike..."
Each time before his orgasm, he would pull his wet cock out of Nina's vagina and slip it into her anus, then he would ejaculate inside her and moan, pulsating streams into her. I could see his hips jerking away with his cock buried inside her. I kept my eyes mostly closed and feigned sleep but I was wide awake and aghast at the goings on. That did not prevent me from becoming sexually excited. Uncle Mike did not visit us every week but he managed to fuck Nina each night he was downstairs, supposedly sleeping on the couch. Once in a while he would come twice in the night and fuck her. Once in a while, I noticed he was still erect as he sneaked out.
In the ensuing two years or so that this was happening, Nina told me that she knew I was watching it all from under my blanket. She said that I could do what Uncle Mike was doing if I wanted to but I never responded. There was, like, a "forbidden" rule on it and my lust did not rise above that so I never fucked my sister. I did masturbate a lot to my memories of watching her raise her butt for Uncle Mike and then watching him pump her, usually for between five an ten minutes until he came in her. Then, he would sneak out of the room.
Sometimes, after he left, I could tell that Nina was masturbating under her blanket, to finish herself off. Even today I remember her invitation and am tempted to call her but she lives 3,000 miles away and is married with two kids. Uncle Mike did her from age 15 to around 17 then changed jobs and moved away. She told me more than once that she loved it when Uncle Mike fucked her and she always looked forward to it.
