In a dimly lit dungeon, a crossdresser, trembling with anticipation, awaits their mistress. She enters, clad in leather, a wicked smile playing on her lips. "Today, my pet, we explore your sissification," she purrs, presenting them with a pair of tight, lacy panties. The sub, already hard, swallow their pride and slip into the panties, the fabric stretching taut over their ass. The femdom laughs, "Look at that, you're practically bursting out of them." She commands them to assume the position, ready to be used and humiliated, their cock throbbing with need.
