A cock blocker.
The little dude literally freaks out every time we start bumping uglies. It doesn't matter if he is in the other room, he still starts screaming in the middle of coitus. We can be quiet as a mouse and he still starts screaming the moment I get my dick wet.
God dammit, I just wanted to take my ol' Lady to pound town.
Let the little fucker cry, ten minutes won't kill him.
