One - and then two - thin, fetish-clad mistresses abuse their slave boy by stringing him up and engaging in some cock and ball torture, which he is all too willing to submit to, and then go out and claim another victim to abuse.
At first their captured muscle man puts up quite the fight, until he learns to like having his nipples, tongue and balls clamped with clothespins, and getting spanked and flogged by his sexy captors. One makes him lick and suck her feet until he gets it right and later fucks his ass with her toes. The two then put on a teasing girl/girl show right in front of him but shackle his wrists and forbid him from jerking off until they give the okay. The sight of the bald, handcuffed slave kneeling at his mistresses' feet is a delight, and they work a perfect blend of teasing, torment and torture, so much so that (surprise, surprise), their new pet winds up wanting to stay. Superb foot worship, bondage, beatings and humiliation.
