Friend has first no desire, but when they hold their pussies in his face, he becomes horny

Hey bud, he's trying to study. You know, he's gonna be an MD. I guess that means

he doesn't want to F-U-C-K then.

Okay guys, you wanna play doctor?

I bet he's gonna tell us to bend over and say "ah". I bet.

Why don't you two bend over and say "ah" for me?
