I owed this person a new ref of the character I'd designed for him a while back. I really like refs that show personality vs just being a stiff T pose or the like. The butt came out really well in my opinion as well.

In my eyes, bird characters are a lot like their animal selves, not having external genitalia (only a cloaca). This makes them wonderfully G rated even in the Bottomless District, but when it comes to pleasing a partner, it can leave them with less options than other species. Shown here is a sort of Bad Birdy "toy" that fits inside of him and is held in place firmly by its shape, giving him a sort of prosthetic phallus. Having sex with partners while wearing this gives him a variety of sensation, thanks to the nubs and bulbs.
