I'm gonna drop a hot take on how Oni releases girls: I'm fine with him releasing them in 3 stages; first with the whole body, clothes and shit but no actions other than handjob. Second, all the 'job positions, and third, all the sex positions. Now, I'm fine with this on paper, because this system, supposedly, works to get feedback on the girl. "Hey, Gwen's face is shit, make it slender", or stuff like that, which he can do easier with less positions to correct.
That should be the theory, at least. On practice, we all know the ol' tale of the lazy Oni and Momotaro, or some shit, right?
