Two straight fraternity bros, curious yet nervous, submit to a 'physical' exam by a dominant gay doctor. The doctor, experienced in gay porn, guides them through their first gay encounter. He slowly undresses them, revealing their innocent yet toned bodies. The bros, twinks with growing erections, explore each other's cocks for the first time, tentatively at first, then with increasing hunger. The doctor watches, encouraging their gay sex, as they suck each other off and fuck missionary-style, their moans filling the clinic.
