With her guard down, Eric whirled around again and screamed out the window a second time. "PLEASE! PLEEEEE-"
"THAT'S IT."
Lisa tackled him, grabbed his head in an iron grip, turned him to face her and violently kissed him.
Eric was stunned, but an instant later couldn't help himself from leaning into it. The sensation was incredibly odd, trying to lock lips with a blunt muzzle, but was no less passionate. She dove into his mouth again and again. Their tongues explored each other -- she tasted salty. Her buck teeth proved an obstacle a few times, but even so...god, thought Eric, this is incredible. His oversized cock surged to attention, rising up between her legs. She ground against it as leverage to probe his face deeper. The moment felt like it went on for hours.
Then she pulled away, as quickly as she had begun. Eric saw that angry tears welled in her rodent eyes. "That could've been every day. I wanted to kiss you every day of my life. Run my tongue around your cockhead and have you feel it too. Instead I had to make that one count, since it's going to be your last." Lisa backed away and stared down at him in indignation. "Tomtom, fuck his face."
"WHAT?! Hey, NO!" Eric yelled in a panic. His gargantuan former pet advanced toward him, expressionless. He scrambled up on his bed desperately, kicking and struggling, but he was no match for the massive beast. Tomtom lumbered on top of him, restricting his movement. Knobby paws grabbed his head and directed it to the rat's turgid penis, impaling his mouth in one swift motion. Eric's groans were silenced as he choked on the thick pole.
It tasted absolutely rancid. After all, Tomtom had spent the last few days in near-constant sexual bliss. Rats are usually diligent about cleaning themselves, but his schedule had been extremely busy. A mixture of Lisa's saliva and juices, his mother's lubricant as a rodent, and dried rat cum assaulted Eric's senses. The flavor was almost more traumatic than the experience.
His entire world was fur, funk, and fellatio. The rat's hips worked up and down, driving his meat in and out of Eric as he flailed helplessly underneath him. Something about the process was distressingly human, and he cursed ever having given Tomtom his advanced intelligence. How much had Lisa tweaked and modified after the fact, too?
Between the wet schlorps and his own strained breathing he could hear her now, typing away at the Chronivac, editing reality even further. Sealing his fate, no doubt. As if on cue, an electric tingle ran through his body, and Tomtom jerked, stopped short, and shot his load down Eric's throat. He would've gagged if he could. The hot cum blasted up his nasal passages and ran out his nose, mixing on his upper lip with his snot and tears.
"There," said Lisa imperiously. Eric struggled to free himself but it was no use, the rat simply laid on top of him, unmoving, still with its dick lodged in his mouth. All he could see was musky rat crotch. He felt Lisa approach the bed and lay next to him. Her hand searched for his underneath Tomtom's bulk, finally finding it. She clasped it tightly.
"I've made three changes," she rasped quietly, almost a whisper. "First, I've stopped any mental changes, so whether or not you enjoy this is completely on you. Second, you were so determined to take all the fun out of this that now I just want to get it over with, so it's all going to happen a whole lot faster. And third, you may have already figured out..."
She cleared her throat. "Third, you're still gonna be a rat cock, but you're facing the other way. What you're seeing now is all you're ever going to see, what you're tasting now is all you're ever going to taste, and instead of kissing my cunt you're going to be blasting seed into it from the other end. It's not a pleasant thought for anyone, so I hope you're happy."
Eric screamed around the cock in his mouth. Lisa squeezed his hand and it dissolved into nothing.
