"Frankly, my dear, I'm not convinced." she says. With that she pushes her tongue deeply into you. You cry out in a mixture of pleasure and distress as her probing tongue is joined by fingers that massage between your legs while she explores your altered sex orally. Her oral skills, combined with the continued attentions of her pet behind you causes a heady mixture of dread, longing and arousal that brings an unfamiliar sensation in your new body. You begin moaning despite yourself as you come closer and closer.
"You're ours now." the blond whispers in your ear "Cat girl pet. Cat girl pet. Cat girl pet..." she repeats. Somehow this helps push you even farther, yet as the climax comes so close you can practically taste it, it won't. Somehow stays on the very peak without progressing further. The bell on the collar around your neck begins to glow and radiate warmth.
"Please...please..." you moan. The pleasure is almost driving you mad and you find yourself caring about nothing else but finally climaxing. As your new mistress enthusiastically licks and fondles you, your will begins wearing down. Not only do you not care if your orgasm will doom you to be a cat girl forever, you find yourself wanting it "...YES!" you cry out. The collar around sends a plus through your body as you finally climax. Your mistress her head away and lays down upon you. The soft snuggling from your fellow cat girls is a warm comfort to you.
"Mine." your mistress says to you, cupping your chin in her hand "Forever." she says. Whatever lingering fear you may have had dissipates, replaced with a warm comforted feeling.
"Yes, mistress." you say. You cuddle yourselves to sleep. When you wake the next day you and your sister happily go about your duties, idly taking about what you'd do if another intruder entered the house.
