My now wife (Jess) was known as a good time when we were in college. Basically, if it was the end of a party she’d find the nearest guy and end up in a room with him somewhere. After a long night of drinking our sophomore year, she found herself in a bedroom with a guy (James). They hadn’t closed the door, and another guy (name is David…more on him later) and I saw her blowing him. She was on her knees facing away from us. James saw David and I watching and starting laughing. She looked up and saw James, and turned around to see us. Rather than be embarrassed she went right back to sucking James, who motioned for us to come in.
I was a bit reluctant, but David happily obliged. He went into the room and slapped Jessie on the ass pretty hard. It startled her but she didn’t stop. David was known in our group of friends for (1) being hung and (2) being an asshole. James was goofy and a fun time. I was similar to James although more reserved most of the time.
