He surprises you...

"A-Alright, but y-you can't tell anyone that we know about this, secretly I'm gay."

Taken aback by this interesting news, you barely notice him going into his jean pocket and pulling out some vaseline and start lubing his ass up in readiness for your monsterous cock.

"Be gentle, you're the biggest guy I've had up there, ohhhhhh........" Before he could finish his sentence, you crouched down behind him and lined up your cock with his asshole and slowly fed it in.
