"...I'll just turn you into my pussy."
"What?!" Eric cried. He jerked out of Lisa's grip and took a few unsteady steps backward.
She clasped her hands together in satisfaction. "Just imagine it. It's perfect! I'll still get to mate with the only creature I want to spend the rest of my life with, but you'll be there too, getting fucked right along with me. Don't worry about getting bored...you'll be constantly filled up full of Tomtom's thick cum, and whenever you're not I'll make sure to finger you day and night. Of course there will be other duties...you'll have to get used to the taste of piss, and pretty soon there will be babies...but oh Eric, we're going to share so much together forever."
His ratlike girlfriend advanced toward him slowly, a slightly crazed look in her dark eyes. Eric recoiled from her further, but stumbled over a pile of clothes on his floor and landed backwards, hard, on his bed. The impact sent a burst of shedded rat fur floating through the air, remnants of his girlfriend's earlier love-making. His hand landed in something sticky.
Lisa leaned above him, resting her hands on either side of his stomach. "I've got the Chronivac program all ready to go. All it takes is an act as the catalyst...you stuff your thing inside of me and you'll be on a one-way train to my tunnel. Now you won't be a rat pussy, at least not immediately, Tomtom and I have a few more days to go to finish that up. But you'll change right along with me, and it'll be just as permanent."
She cocked her head to the side thoughtfully. "Y'know, I'm not sure which parts of you will end up where in my anatomy. But I expect..." She reached down and dipped two fingers into her sex. "...these flaps of skin up here..." Before Eric could protest, she ran her lubricated fingers along his lips and down inside his mouth. "...mmmm, these are going to end up as labia."
Eric sputtered and spat out her fingers. He felt violated and utterly disturbed, but...now something in the air was affecting him. Rat dander from his bed? The taste of Lisa's juices on his tongue? He shook his head. "Lisa, I don't want this. I won't let you do this." His eyes darted to the Chronivac.
"Oh, you're completely transparent." she smirked. "You'll want this. Very soon, if not already. I started some of the alterations the moment you pulled into the driveway. But it's going to be a nice slow burn, so we'll be able to enjoy it."
Lisa straddled his body with her knees and ran her hands along Eric's chest. Her teats were erect and standing at attention, and her fur bristled. Slowly, she spread her legs apart and lowered her pussy over his growing bulge. She "kissed" the outline of his cock with her lips, and as she rose back up a string of clear fluid remained, connecting the two of them.
"So...shall we get started?"
