I would give him a butt massage while kissing and licking his butt cheeks. Then rub my dick between his butt cheeks and hump back and forth until I cum all over his butt crack. Feeling his butt bouncing underneath my cock would be incredible.
Nice ass I'd suck your dick from the back & lick & suck your dick , balls , taint & ass & tongue fuck your asshole while I jerk u off til u cum hard;-p
