a fursuit modified for yiff.
on a male a hole would be cut for the penis to come out and one for anal sex.
on a woman one hole for vaginal sex and another hole for anal.
(as i side note, i would like to state that only a small number of furrie's own them)
fur one: hey, my mate has a murr suit
fur two: no way, thats awesome
fur one: i know. it was so much fun to be fucked by his fursona.
