The clinic's dim lighting casts a sultry glow over the Thai twinks as they undress, their slim frames and uncut cocks on full display. Dr. Collegeboytoursex, in a white coat and gloves, guides them through a series of 'tests' designed to push their boundaries. He runs a stethoscope over their chests, then down to their groins, listening to their hearts race as they grow erect. He lubes up a finger, slipping it into one twink's ass, making the boy gasp and moan, while the other twink watches, eagerly awaiting his turn.
