Mistress Evelyn is an expert at edging out a slave's big load from their helpless balls. There is nothing more satisfying to her than getting a tied up boy so on the edge that he can cum buckets without a hand even on his cock. A true ruined orgasm! With every stroke of pleasure comes a bit more pain to his balls as she slowly closes the vice inch by inch making it as tight as it can possibly go. Once the vice has his balls a beautiful shade of purple then she knows it's time to ruin his orgasm the best way she can.
