In the dimly lit room, a lone figure sits, his heart pounding with anticipation. His hand wraps around his throbbing cock, the foreskin sliding back and forth, creating a unique, intimate friction. He pumps harder, the sound of skin slapping against skin filling the room. His breath hitches as he feels the familiar tingle in his balls, the precursor to his impending release. With a final, powerful stroke, he feels the warm, sticky cum gush out, filling his foreskin and dripping down his shaft.
