Mr X, bound and at Mistress Ae's mercy, suffers her latex-clad body grinding against his, her fishnets abrading his skin. She pinches, twists, and slaps his cock and balls, pushing him to his limits with expert CBT. As he gasps for breath, she denies him air, heightening his senses with oxygen play, before finally allowing him to worship her pussy with his tongue, edging him close to climax only to cruelly deny him again.
