Mistress Isabella Sinclaire is a sexy blonde who knows a thing or two about ball control. But she's no Kobe Bryant. Instead, she wraps up some dude's testicles and uses the slack end as a leash to yank as he crawls around on the floor and while he's bound to a rack.

The dude's nuts take a beating for about 45 minutes as she binds his naked body in various ways and gives his privates plenty of swift kicks and whacks him with a riding crop.

Though it sounds painful, he obviously loves every minute of it, since he stays hard for nearly the whole time. In the end, he worships her feet with his mouth.

Retailing: Stock wherever boys get beaten.
