Friend's Brother

I'm 36 and a single mum.been single for nearly a year.i was walking home after dropping my daughter off at school when i bumped into my friends 14 year old brother.as his school is near my house we walked together and did that each day for a few weeks.he was a little cheeky but i let him , even when he groped me i still didn't stop him.so one time i called his bluff and asked if he wanted to come round instead of going to school, straight away he said yes.i went along with it thinking he would change his mind,then we get inside my house and he said he needed the toilet,i was still thinking he would come out and leave. I'm sitting on my couch when he came in the room and was completely naked and aroused,I was laughing just wasn't expecting it.maybe i should have asked him to leave but i never,I ended laying back naked and letting this lad fuck me and we been having sex ever since.
