In a clinic's storage room, twink brothers, both horny and curious, explore each other's bodies. The younger one, clad in only a white coat, pulls down his brother's underwear, revealing a growing bulge. They kiss, tentatively at first, then with increasing hunger. The older brother strokes his sibling's erect cock, feeling it pulse in his hand. They move to a nearby table, the younger one bending over, his ass exposed. The older brother lubes up and pushes inside, fucking him slowly at first, then with increasing intensity, until they both cum, the younger one's jizz splattering onto the medical texts.
