A bound and gagged trainee is the centerpiece of a kinky threesome, her body a canvas for rough, bizarre pleasures. She's tied tightly, arms and legs spread wide, as her mistress and lover take turns whipping her, their floggers leaving marks on her skin. The trainee's mouth is stuffed with a thick dildo, muffling her moans as she's fucked hard from behind, her body shaking with each thrust. The couple's rough play is interspersed with tender, loving moments, pushing the trainee's boundaries and exploring their own kinks.
