Knee Sex

Cousin K: Last time I was at the beach, I exfoliated my knees with the sand.

Brother 1: What? Does that turn you on? Ohhhhhh look at how smooth my knees are! I love it when my knees are smooth, sometimes I go upstairs, take off all my clothes, and sit on the couch rubbing my knees together. Ohhhhhhhhh yeahhh!!! Uh uh uh uh uh!!! Ahhhhhhh. (about 5 minutes of sex noises)

Brother 2: You're so gross.

Brother 1: Yeah, and then Mom comes upstairs and is like, "What the fuck are you doing?"
