King Mark tests Calvin's limits in their kinky domain, ordering him into chastity and foot worship. Calvin, ravenous and humiliated, licks Mark's soles, his tongue tracing the ridges and curves. But Mark craves more, binding Calvin to a St. Andrew's Cross. With a cruel laugh, he begins a relentless, toe-curling ballbusting, his feet slamming into Calvin's crotch, again and again, until Calvin's screams echo through the dungeon, his body convulsing in a mix of agony and ecstasy.
