Muscled twinks, bound and collared, are forced into pushup positions. Their masters, watching sternly, demand perfection. Any mistake earns a harsh smack on their bare asses.

The real test comes next: the slaves are bound and penetrated anally, their screams muffled by gags, as they're fucked hard and deep.
