Mark, a lanky, eager crossdresser, steps out into the bustling city, his heart pounding in his chest. His first time out in public, he's adorned in a tight, lacy dress and heels, feeling the cool air against his exposed skin. He walks, his movements exaggerated, feeling the stares and whispers. His cock grows hard, tenting the dress as he passes strangers. Desperate for release, he finds a secluded alley, pulling out his cock, stroking it furiously. He cums hard, his body shaking, then quickly tidies up, panting, before continuing his humiliating, exhilarating walk.
