Base +37

The irony of the pixelated pixel dick.

Base +6, daretofight +7, the dru one +7, primeemu16 +6, DJMyke +6, CFYBRS +6, Gim-Li +10, Morehead +6, afsafsfasdf -4, Pliny the Younger +6, sissam +6, FlurrieFour +6, Brutless +5, and 3 more...

I'm guessing its supposed to be animated?

These are... frame by frame gifs, then?

That's. I guess that's ONE way to post a gallery.

TheAveinator97 converted them into animated GIFs but the gallery was expunged by idiots:

I guess there's no good ending here? Though since these monster girls tend to be monogamous I digress.
