Several years ago, I had a roommate. He used to bring this closetcase (never knew his name) home and they'd smoke pot and fool around in his room. Roomie abruptly moves out.
A couple weeks go by and I am passed out on my couch. It's late, and there's a knock at the door. I don't bother turning on the lights. Standing on my porch is this drunk guy looking for my roomie. I tell him he moved out, and he leaves. I lay back down and a minute later he's knocking on my door again.
He asks to come in, and I let him. Mind you the lights are still off and the only light is coming in from the lights outside in the parking lot. I can't see his face. We make small talk, standing there in the dark.
Long story short, a few minutes later I am balls deep in his ass. He came by a few times after that, but the last time he puked all over my apartment and I told him not to come back.
I never did learn his name.
