The kitty swallowed nervously and looked over at her older sister, but before she could even say anything you pressed your face against her slit! Your tongue pressed against her as she let out a high pitched moan! Rolling her eyes back and drooling, eyes rolling into the back of her skull. Holding onto your head and drooling onto her own bare tits, her legs shaking as she tries to pant. "S-sis is gonna be so drained... Ahh! I want- her- to choke out while she loses...every..thiiiing!" She cried! Feeling her labia lapped by your dexterious tongue! Coming up with plans against her sister and getting aroused by it all the same! And in less then 30 seconds, she came hard in your mouth! You drinking her Sp and she screaming!<br/><br/>Soon she started getting flatter! She screamed as her body shrunk! Her chest getting smaller, her body shrinking by a foot or so while you drank every once of her SP! Her pussy getting tighter, she drooling and her legs shaking! She getting smaller and smaller as she continued holding onto your head, pulling your hair a little as she falls down on her butt.<br/><br/>Meanwhile, your hips get wider, your chest gets even larger! And you now feel completly full As the girl below you whimpers.
