"...You're going to be another of Tomtom's mates."
"What?!" Eric cried. He jerked out of Lisa's grip and took a few unsteady steps backward.
She clasped her hands together in satisfaction. "It'll be great! You and I will still be together forever, but as sisters, getting filled up by the same cock. I'll still get to mate with the only creature I want to spend the rest of my life with, and if I ever get worn out from the fucking, I can kick back and watch you two going at it instead. And there'll be threesomes, and we'll finger each other, and we're going to get soooo pregnant, and have babies, so many babies..."
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. Tomtom's cum should have the same effect on you that it did on me...you can suck him off, or he can fuck you -- maybe we'll give you a pussy first, that might be easier? -- and you'll become more like me each time, 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."
She got off him and moved to the rat cage, and plucked Tomtom out of it. Eric heard his mother-turned-rat shriek. Lisa held Tomtom up toward him and shook the rat slightly, suggestively. Dribbles of his rat batter landed on the carpet below. Eric saw Lisa's miniature tail writhing behind her with anticipation.
"So...shall we get started?"
