Puppy play has never been a kink of mine but I think it‘s one of the best options for VR and it really thrilled me in this game. I‘m not through this game yet, so maybe some things are yet to come, but I was thinking of some scenes that would fit so well, like having Yuki-Onna throwing things and have her puppy to bring them back to her. (Problem here would be to pick things up with your mouth. Maybe some specific head movements for picking and dropping could be introduced here)
She could instruct you to keep crawling on your knees if you try to get up or occasionally to keep your head low guiding you just with her voice to her feet. When approaching her you either have to drop the object to her feet or present it in a typical puppy pose.
You could make use of the guarded vr area to throw the objects where the player can reach them.
Then what about using Onna and Nega both to get you into trouble by forcing you to choose whether you want to be a toy or a puppy. There could be a hot conversation letting them explain to you what to expect.
You‘d get a special reward session with the winner mistress like leg humping with Onna or a mouth dildo with Nega.
Whoever you choose you‘d get into trouble with the other one and would have to beg for forgiveness in a next encounter like making some specific puppy poses for being sorry for Onna.
Having me close to their pussy (no touching) even with panties on and some hot talking would also be a great scene.
You could also add some kinkier options like a golden shower by asking whether the player would like that. Talking him into those things would also be definitively hot.
Please continue the great work. There is still so much potential to this game.
The talking of the mistresses is definitively one of the best things in my view. Compliments to the ladies giving their voices.
