Nyahing out cutely and humping the air some more as you touch her fluffy new butt, showing off how sensitive her asshole is now. Much to her shock, as her desire to cum only grows, but nowhere near to getting the sweet release she needs. Barely paying attention to whatever nonsense you are talking about, still smirking and panting at her own reflection, with her legs still up in the stocks and being cute. Watching you block her view as you get more into the teasing of the young kittygirl. Sticking your finger into her asshole directly this time, as this gets her attention, eyes shooting wide as she howls like mad! Clearly not liking it as she flips the fuck out, thrashing hard in her stocks and clenching your finger tightly in your butt. Slipping it back out fast and not catching that part about being able to cum, still reeling from what you did to her butt. Which is quite the reaction coming out of her and something you've never experienced before from a petgirl. But, then again, you've never played with their butts until this one showed up...
