When I was 15 my sister had a boyfriend who was in college and she was a senior. My parents were out of town this one weekend and she had him over and they smoked some pot in the backyard and got stoned. They went to bed and so did I and later in the night I woke up with her boyfriend getting in bed with me. I was scared as hell and he told me to be quiet and we would have some fun. I gave him a hard time when he went to get my panties off and he got all serious and told me to lift up my butt. I did just to go along and then he laid down right on top of me. I could not believe it when I felt him go inside me and he kissed me and told me how great I was. He didn't take too long before he went off and then he just stayed on top of me for a while and then was back at it again. Turned out my sister knew he wanted to do this and she let him. Lucky for me I did not get pregnant.
