Derby Balls

An enjoyable form of BDSM play whereby the male scrotum is exposed and beat and slapped repeatedly with a riding crop like the ass end of horse running the Kentucky Derby.

My mistress pulled my scrotum from my fly and gave me derby balls. The pleasure was incredible.

I feel like I’m ready to run for the triple crown after having my scrotum bashed in the most delightful session of derby balls last night.
