The doctor, a twink himself, can't help but feel a stirring in his scrubs as he watches his young patient squirm. "I need to check your reflexes," he says, his voice steady despite his racing heart. He runs his fingers down the twink's leg, making him jump. "Sensitive, aren't you?" the doctor remarks, his thumb brushing against the inside of the twink's thigh. The twink bites his lip, trying to hide his erection. The doctor smirks, leaning in. "I think we need to check something else," he says, his hand moving to the twink's crotch, making them both groan with anticipation.
