quick Cuckoo Mask RPG heads up

CM testing is halfway done. Technically, all NSFW parts work well, and I'm currently testing the story sections. In theory, I could post the build now, but players might get stuck in the unfinished story parts. I'll run more tests for a couple of days before releasing it.

So please have some patience, the build should be ready soon!

Cuckoo Mask RPG titsucking + handjob character poll

Hello, right now I'm working on a titsucking + handjob scene in Cuckoo Mask.

Serena can let you suck her boob while jerking you off (or touching your cage if you're caged) and she can do it to strangers. But I wanted to add an unique scene with one of the other actual bulls!
Do you have a preference on which characters?
