A naive young newbie on his first job is tricked by his buddies into thinking he is scheduled for an annual physical.
The "doctor" tells the newbie to sit on the examination table doggie style while he administers a thorough and extensive anal probe. The newbie can't see what's going on behind him, and has no idea of the varied objects the "doctor" is inserting up his butt hole.
Meanwhile, a security camera is recording the exam, and the rookie's pals are cracking up watching the show on closed circuit TV. After the rectal work-up, the "doctor" milks the newbie's dick to get a smear of pre-cum for a slide (or 2 or 3). The "doctor" tells the greenhorn the pre-cum looks suspicious, and says he'll need a semen sample
As he pumps the newbie's dick, the "doctor" asks the rookie extensive (and embarrassing) questions about his sex life: When did he first masturbate? How often does he masturbate nowadays? Has he ever masturbated with other guys? Ever have oral sex with guys? Ever have anal sex? Ever have sex with a woman? With a hooker? How did he lose his virginity?
By this time, the guys watching the show on closed circuit TV have all jacked off, and got themselves a brand new video to play at stag parties.
