The Luxray snores cutely, sleeping on her side with her big, round belly splayed out on the floor. Your synthetic body resists her acids for some time, certainly longer than a creature of natural flesh, but you gradually become gooey silver chyme nonetheless. Your liquid self, along with your leftover hard and pointy bits, funnel down into her intestines to be assimilated into her flesh. The Luxray squirms and moans in her sleep as your metal chunks wind their way through her intestinal maze. Impressively, her clenching tubes along with powerful enzymes are enough to grind your bones and talons into dust, which is sprinkled among the nutritious goop your body has become and ultimately absorbed into her ass. Even your tomahawk horn meets its end in the kitty’s brutal digestive tract, becoming naught but a bit of iron for her body to metabolize.
As her big, blue gut works you down, her black pillows begin to expand. They wobble and creak as they’re packed full of synthetic Silvally assfat, growing from twin watermelons to the volume of beach balls over the course of an hour— but you’re not even halfway done! Still the majority of your mass resides in her gut as gooey fuel, waiting to become one with your predator. You have a lot to give, and it takes the entire duration of her long sleep, but her black booty accepts it all. Nothing goes to waste, and by the time it’s over, the Luxray’s ass cheeks look as if the entire weight of your body had been crammed in beneath her flesh as soft, doughy pudge— because, well, it was. A bit of energy was lost in all the chemical reactions, but it seems your body composition allowed you to be absorbed in your entirety. You are quite literally nothing but Luxray ass now.
The cat rolls onto her back and purrs as she strokes her shapely belly, always such a nice feeling after digesting a big meal. Her belly might be done with you, but her rump’s going to have to deal with you for years to come...
Finally waking up, the sleek kitty rolls to her feet and mewls in surprise as her ass almost pulls her back down. She looks back at the inordinate black orbs mounted on her backside— pumping out her hips to about twice the width of her torso— and hesitates for a long moment before cracking a faint grin. Yawning, she stretches her paws out in front of her and leans forward, then rocks her hips side to side. The monolithic mounds of fat that are her ass cheeks wobble and sway, their weight nearly dragging her whole body along with them! That mystery creature made a much bigger impact than she expected— usually sending a male to her hips results in a couple more manageable layers, but these mountains of flab he gave her are downright ridiculous! They’re about as large as half her own body, and surely comprise nearly half of her body weight! How in the world is she supposed to walk with these squishy boulders weighing her down, let alone run or jump?
“Humph… you sure were a lot more fattening than you looked. Are you happy on there, horny boy? You’ve made me into a wrecking ball.” Given the creature seemed to have some robotic parts, perhaps whatever energy was powering him caused him to turn into so much fat… the Luxray briefly wonders about the origin of her booty’s latest passenger. She’d never seen anything like him— was he a legendary species? Perhaps the only one of his kind? Has her ass erased an entirely new Pokémon species from the face of the planet?
“Hmm…” the kitty hums as she sways her rump and appreciates the massive cheeks wobbling and slapping against each other. “Whoever made you must not have programmed you very well. Unless your function was to crawl up a lady’s butt and make her ass huge, in which case you’ve succeeded.” She slams her rear into the ground, growling at the feeling of her fat rolls spreading across the soft ground. “In any case, you’ll be better off back there than wandering around the forest.” She grinds her chimera-padded ass back and forth on the ground, causing a purr to rumble out from her chest. As inconvenient as it is, he feels lovely back there. She’ll need to develop some new muscles to get used to hauling him around, but perhaps she can use her inordinate booty as a means to capture additional prey, rather than exerting herself trying to chase or fight them… Surely most males would be at least temporarily stunned by the sight of her.
