the button 0 don't appear when im trying to tame rabbit in the story mode
That's a taming sex. It cannot be canceled.
Once a wild fapet catches you during a Taming Procedure, it will count as Forced Sex, and you won't be able to cancel it.
Such as: Neko, Hound, Bunny, Warng, Goblin, Harpy, Ent.
But there are Fapets that do let you cancel it: Stallion, Cow, Sheep.
So how do i do for not have a forced sex with bunny because when i press c and q during the scene the button 0 don't appear
Is the Bunny already tamed, right? Pretty much it should appear right after interacting with her (doing the scissoring sex pose). Otherwise try to:
1) Start the sex, press F5, now hold F2 and wait until the bunny reaches the climax. Now try again if it appears.
2) Restart the game .
I try what you said but that don't work but the button appear only when i doing the sex training. And i think the game consider the scene is forced or its my fault and i do the wrong martubion pose and for the sex with bunny do i need carrots
