In the sterile, fluorescent-lit clinic, the doctor's fingers dance and dive, mapping the uncharted territories of his patients' tight, untouched asses. The twinks, their breaths ragged, grip the table's edge as the doctor's gloved hands tease and tantalize, their bodies responding eagerly to the invasion. The doctor, his cock straining against his pants, leans in, his voice a low rumble, "You're both so incredibly tight. I've never seen anything like it." His words send shivers down their spines, their cocks throbbing with anticipation, ready to graduate from medical students to carnal disciples.
