I went over to my boyfriends house and he told me his parents were not going to be there. During the day, we were both in the mood and in the living room. I know it's kinda dumb in hindsight, but yeah anyway, i was bent over on his parents couch getting absolutely fucking pounded, hair pulled, ass slapping everything. My boyfriend was so into it, he didn't notice everything, but while I was in the middle screaming cumming, out of the corner of my eye i saw his dad looking from the hallway. He left immediately and my boyfriend kept going hard until he was done and we went back to his room. After a good amount of time passed, we were in my boyfriends room and his dad stopped by to say hi and we had a casual conversation for a minute and he played it all of, as if he had just gotten home.
