I am made fun of at university for still being attached to my teddy bear. It makes me upset so I come to my big bother looking for comfort. He cheers me up but not in the way that I have expected. I accidently touch his cock and we slowy start to do what we are definitely not supposed to. I am so scared that our parents are going to find out but it just feel too good for me to stop. We are close like we have never been before. I ride on his dick still a little embarassed. I tell him not to get me pregnant because our parents are going to be furious but, despite that, he cums inside of me.
