Mistress binds slave's cock and balls brutally tight with coarse rope, yanking and jerking the swollen shaft until he writhes in agony, pre-cum oozing from his tortured tip. Spins him ass-out for savage palm spanks and whip cracks on trembling cheeks, red welts rising fast. Flips to front: she strokes the throbbing rope-bound cock teasingly, then delivers stinging ballbusting slaps, alternating brutal pleasure-pain CBT torment.
