In the dimly lit room, a muscular Adonis, his body glistening with sweat, sits alone. His massive arms flex and relax, showcasing his toned physique. He runs a hand over his chest, pausing to tweak and roll his hardening nipples. A smirk plays on his lips as he leans back, his other hand reaching down to stroke his growing erection. His breath hitches as he picks up the pace, his nipples remaining rock hard, matching the throbbing of his cock.
