Last weekend I was getting a blow job from a new gal I had met at a party. But shortly after she began, she stopped and said ewww... you've been with someone else today. Then she got angry, backed off and told me to go home and take a cold shower. She was right. I had received a blow job from a different gal earlier that day. But how could she possibly tell?
if your cock tasted like someone else's lunch, that's a dead giveaway.. https://www.youtube.com/watch?v=lgWgEoaAYDY"]Riskay - Smell Yo Dick - YouTube
You had one of her head hairs wrapped around your cock and it got in the new girl's mouth! That had to be it! Yuck-o!
