I Ended Up Letting Him

I was only 13 at the time when my mum would leave me at home at night,I remember my cousin was 19 came round about 11 o'clock that night,we ended up chatting in my bedroom I was wearing a nightie and knickers,he was saying i looked cute and then came over kissed me which forced me to lay back,he got on to his knees and reached down to his jeans and heard him unzip,I lifted my head a little and looked at that moment he pulled his jeans down just enough for his dick to come out which was hard already,he pulled off my knickers and layed down on me,I felt his dick go in each time going in further,I didn't stop him i just let him do it and let him cum,he got up and zipped back up and said thank you to me,I didn't tell my mum,few days later he came by again it got to a point where I was used to it without it hurting,I would just lay there and let him get on with it hearing him groaning as he cums,we occasionally meet up still.
