"...I'll transform you into Tomtom's cum, and you're going to get me pregnant."
"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's the perfect solution. Tomtom is the only creature I want to mate with for the rest of my life, but I still wanted you to be part of my life, and now you will, literally! You get to take part in our lovemaking, and then you'll grow inside me, and be reborn as a rat like us -- probably one of a litter, I'm not sure how we'll know which one is you, but we'll work out the details -- you'll suckle at my teats, and I'll raise you, and eventually you'll give me grandchildren of my own...oh Eric, we're going to be so happy together!"
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. "This was a lot trickier to figure out on the Chronivac, but I think I've got it ready to go. We'll have to slide you down Tomtom's dickhole to get the process started, and there are safeguards in place to make sure you fertilize one of my eggs instead of one of the other swimmers..."
She cocked her head and bit her lip with her too-long incisors. "My little sperm man...it won't be long before you'll be enjoying my placenta for every meal..." Before Eric could protest, she yanked him up by his shirt into a passionate kiss, lips-to-muzzle. Her whiskers brushed against his cheek, and she thrust her tongue into his mouth.
Eric sputtered and pulled away. He felt sick and utterly disturbed, but...now something in the air was affecting him. Rat dander from his bed? The taste of Lisa's 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."
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?"
