Lisa rolled her eyes dismissively. The effect was disconcerting, on a mostly-rattish face. "Your mom? She was nothing but trouble. I thought the neighbors were going to call the cops, the way she screamed when she caught me and Tomtom. That woman has pipes on her! Heck, she still does. You can hear her right now." She motioned toward Tomtom's cage. In the quiet moment, Eric realized he could hear a faint rustling and squeaking.
Eric felt sick, but couldn't stop himself from stepping closer to the cage. His legs were wobbling. But he had to know. He peered inside.
Tomtom was happily humping away continuously at another rat, a fatter female with grey around her muzzle. The fur on her head was the same color as Eric's mother's. Her tongue lolled out as she panted, squeaking softly with each thrust.
"I made a couple quick changes with the Chronivac and that took care of the screaming. I put her inside the cage to watch us finish up, and then I thought she looked lonely so I shrunk Tomtom back down and gave her a go. She wasn't willing at first so I gave her some of the same adjustments you gave me, and they've been at it for a couple hours now. I've been watching them as I was waiting for you..."
Eric felt a knobbly hand run across his shoulder and fur brushing up against his shirt from behind. "And now you're...here..." Lisa breathed into his ear. Whiskers brushed his cheek. Her warm breath smelled like rat cum.
