Thank you so muchOh just have a couple of stiff (sorry about that) drinks before you offer you ass to the big cock and you'll be surprised at how large a cock you can manage. As long as he'd nice and hard there will still be enough give in his meat to manage to penetrate you anal cavities and give you satisfaction, just think after the guys fucked you he's going for your wife and her cunt will accommodate him easily.
As a good test if you can get his cock in your mouth then your asshole will be able to take it as well.
