Ooooh....he could of course lose that delicious new pussy he's gained ;) And maybe get bigger breasts, :) This is a fantastic caption, I love it!!
I've seen quite a few vagina replacing the anus exchanges from you. What if the anus is replaced by something else? Maybe a dick or a mouth or something completely off the wall.
I've considered doing something like that, but I never know what kind of reception that would get so I've been afraid to do one. However, I haven't done an orifice swap in a while, maybe we'll see one in a couple of days?
