The pain is just too much to bear, and you let out a terrible howl of agony.
"Ten."
You worry about the punishment, worry that she might just grab that rod of hers and beat you to death with it, but she doesn't. Instead, she walks out of the room for a moment, returning into it with a can of... something. Whatever it is, there's smoke rising from it - it must be extremely hot. For a while, you just sit there and eye her carefully. When she produces a round metal object and dips it into the can, lifting it to show the substance - a shiny black tar - dripping from it, you try to get away, despite being bound. You pull back as hard as you can, trying to keep yourself too far from her, but it's not enough. In a flash, she's dropped the can and grabbed you by the hair, pulling it and forcing you to your knees. You feel a searing pain as she touches the metal cylinder to the base of your spine, and then feel nothing as your mind goes blank.
When you wake up, you can't tell how long it's been. You become vaguely aware that there aren't any windows in this shop, as not even a single stream of light enters from outside. Something's rubbing at your angle... a rope of some sort? No, you can easily move your ankle away. Reaching for it with the hand that isn't restrained by the handcuff, you pull it to your front so you can look at it. It kind of looks like a rope, kind of a black and shiny one, but why...? You move your hands down to its base, and eventually jump to your feet with a start, letting out a yelp as you find it to be attached to you, right where that metal cylinder had touched you. Again gliding your hands along its length, you come to realize fully what this is - that substance that she touched you with has apparently grown somehow into your very own latex cat tail. You try to pull it off, but it hurts far too much.
"Oh, that won't work. It's very much a part of you by now." You look to the door, your cat-like captor staring down at you. "Now you know the nature of your punishments. Stand up, it's time for another game. Succeed and I let you leave. Fail? I'm curious to see how you'd look with a pair of ears to match that tail."
