Innocent twink, new to the gay scene, walks into a clinic expecting a routine check-up. Little does he know, the doctor has other plans. The seasoned grandpa in a white coat, with a glint in his eye, begins the examination, his hands lingering a little too long on the twink's smooth, firm body. The young man squirms, feeling a strange, new sensation as the doctor's touch sends shivers down his spine. The doctor, noticing the twink's growing erection, smirks, "Seems like you're enjoying this." The twink, blushes, realization dawning, as the doctor leans in, ready to give him a lesson he won't forget.
