First robot lady design sketch (Patreon)

In case you don't remember, the next box opening is supposed to be about a robot lady stretching the girl's ass with a strap on.

I'm already pretty happy with this design but I might do some more.

For her name, I was thinking C.A.S.S (continuous anal stretching system), let me know if you can think of some other more clever acronym.

Also, maybe the dildo is still a bit too big for lvl 1 haha.
