Mistress Summer has had her boy toy slave locked in chastity for a long time and knows he is desperate to be released. She just might relent and unlock him, but only if he proves himself to her satisfaction first. It won’t be easy as she intends to put him through a long strapon ordeal with her huge cock. He needs to take it properly and without complaint or he can forget his reward. For her it is fun plowing his ass deeply and hearing him moan. For him it seems endless and he tries his best to take it well for his mistress. Mistress summer loves to see him wince and squirm as she rams the dick deep in his”pussy” as it demonstrates her total dominance and superiority over her slave. The slave is suffering well for her, but will it be enough to earn his chastity release?
