@Mr_NutterButter hmmm depends on what you classify as the end of an ass. if you go past the colon, i've seen dildos as long as 3 ft (don't ask don't tell). otherwise it is about the same size as a vaginal canal, technically.

however, a vaginal canal can stretch in length whereas your asshole isn't as pliable unless we're talking width (and still not even then). a whole baby has to travel through a vagina but we only have shit come out of our ass so that makes sense.

stretching this much probably still doesn't feel that great to most women, though. the kind of girls that do this are a bit masochistic and practice it a lot, and judging from her account it looks like that's her whole shtick.

but yeah anyway, if you're brave enough you could stick that whole thing up your ass is what i'm trying to say. wouldn't feel great but it probably doesn't feel that great for the majority of women either. it's why girth/angle matter more than dick length, if you hit that cervix too hard it'll zap her. this chick is probably pretty snug up against it and maybe even has a technique down at this point.
