This is the nightmare of most girls, giving a blowjob after your butt was drilled hard, also known as ass-to-mouth. In some cases a dick will pick up some of your own shit after an analsession, nothing you can do about that(assuming you whiped your ass clean after shitting). After a few licks on his dick she realizes she got the victim of a real ass-to-mouth and all there is left to say is `eueuhhhh`.
