beadwork ball-strap
A beadwork ball-strap is a beaded leather strap that a guy wears around his sac-de noix to pull his nut-sack away from his body, thereby prolonging the time it takes to have a beadwork ball-stap-gasm.
Matt bought me a beadwork ball-strap and wants me to wear it sometimes so I don't cum too soon when he's fucking my asshole and rubbing my p-spot!
