Nude Butt Cheeks. Film At 11.
stupidpetowners wank that isn't about pets! But it does have plenty of stupid.

In a post about someone who won't take her dog to the vet because she's saving for a house, morriganslayde uses a scandalous! icon! which has, um, some derriere partially exposed but somewhat clothed. hedgemom takes offense, and caroljoy calls the OP "these people" to boot, offended at the relentless depiction of "a sexual act." Someone evokes bbq nipples. morriganslyde apologizes and changes the icon she used for the post, but it doesn't seem to be good enough, because caroljoy and hedgemom keep at it, the latter concluding "a pet forum isn't the place to be militant, "in your face" with your adult, x-rated life. Keep it in your own journal."

Apparently there's some past history there with hedgemom, as well, and that gets mentioned too. And sex workers of all kinds are insulted by someone else entirely. (I for one believe that scantily-clad rear ends might just be the key to world peace. Oh, and boobies.)

(Would it be tacky of me to point out that now the OP's icon for the post itself has a fully exposed pussy?)

ETA: tianxiaode has kindly pointed out some spillover. She's dissing boobies now! Them's fightin' words.
