I was watching hentai at my college roommates house and I asked if I could use his fleshlight, he said fine and I could hardly get it in it was so full. I left the room to wash off and ended up running into his (37 years old) mom who is insane and a nympho, one thing led to another and we ended up having sex. She is now pregnant. I ejaculated onto her neck but I am worried that there is a possibility she could have got pregnant from her sons semen which was fresh on my penis. Should I be worried about this? It would really freak him out.
