"Lie down, please," the doctor instructs, his voice steady despite the sight of the young man's erection. The twink complies, his body tense with anticipation. The doctor's hands, slick with lube, wrap around the young man's cock, stroking it slowly, methodically. The twink gasps, his hips bucking slightly. "Stay still," the doctor commands, his voice laced with a hint of dominance. The twink bites his lip, trying to comply as the doctor's hand works his cock, bringing him closer and closer to the edge.
