"...I'm going to make you into Tomtom."
"What?!" Eric cried. He jerked out of Lisa's grip and took a few unsteady steps backward.
She took on a thoughtful look and reconsidered her words. "Well not exactly him. He'll still be him. But you'll also be him. And it'll be awesome! That way I'll still be with you, technically, and you'll get to enjoy it, and I'll get to mate with the only creature I want to spend the rest of my life with. And when either of you get tired, I'll have twice the dick to go around!"
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. "We won't even need the Chronivac for most of it. My cum should have the same effect on you that his did on me...I'll fuck you, you'll become more like me, then I'll fuck Tomtom and become more like him, and after a few days..." She walked her fingers along his chest. "We'll be a big...happy...ratty...family."
Eric breathed heavily. He was utterly disturbed and grossed out, but something in the air was affecting him. Rat dander from his bed? The scent Lisa was giving off? 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. A string of clear fluid dribbled from her altered vagina and landed in his belly button.
"So...shall we get started?"
