The Cousin Eddie 

When having anal sex, you bust a nut in her ass and yell; “Shitter’s full!”

We just watched National Lampoon’s Christmas vacation. So during sex last night I came in her ass and yelled “Shitter’s full!” The Cousin Eddie never fails to make her laugh.

the italian cousin

When having sex in a college dorm, right before the man finishes, he pulls out and skeets on the roommate whether she is sleeping or not.

Janet's room is so small that I can try the Italian cousin on barb.
