This is a hazard of being a cocksucker... If you're in the wrong (or right) position, while you're concentrating on sucking a big dick, your partner starts playing with your ass – first with his finger, then two fingers, then his hole hand... Then, before you know it, he's punchfucking you with his whole "fucking" arm!
Well... OK, so it doesn't happen a lot. But see it happen here, as Amerifist gives it good to bottom pig Putexib, on Fisting Central.
