Base +37

The irony of the pixelated pixel dick.

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.
