Keep this skunk horny. She managed to get her to pass out from a blissful orgasm by playing with her ass, now she could collect her cum for her ultimate plan, creating a serum that would fulfill her disgusting desires. Turning some knobs, she waited for the signal that her “wet dream” enhancer was working. Cue the passed out herm, who was now moaning, blushing, and getting erect again, Mina prepared to get to work. “All of my experiments are finally paying off here, the musk of a hyena, the filth of a pig, the gas of a cow, and the urine of an alpha wolf, all combined in this one mixture, stored in the sewers for maximum effect, and a few chemicals for good measure. All combined with this skunk’s DNA and funk, I’ll be the most vile creature in existence!” She turned her attention back to Marina, who looked like she was about to blow. Flipping a few switches on her machine and turning more knobs, she sealed the deal by kissing Marina tenderly, causing her to shoot out the biggest load she had ever seen. Even horses don’t cum as much as she was doing right now. After the machine sucked all the cum out of Marina, it let her go, setting her back in the couch as she kept on sleeping. Mina, on the other hand, was packing up her equipment and getting ready to disappear, but not before whispering to the sleeping herm, “thank you, Marina” and closing the door behind her.
Once back in her lab, Mina mixed the final ingredients together in her serum. It turned out being a deep blue color, which she found odd, but was proud of completing anyway. After documenting her findings and copying her procedure down in case she needed to undo anything, her nerves started acting up. She had all this anxiety, not believing that the serum would even work like she had researched, or worse, that it would just flat out kill her. Looking through her notes one final time, she resigned herself to her fate. Uncorking the test tube, she pinched her nose, and took the whole serum on like taking a shot. Her immediate reaction was that it was thick, and bitter. She could feel it going down, like it was semisolid. Once it got into her stomach, she decided to change her clothes from her more professional doctor’s clothes into some baggy sweatpants that she left in a gym bag and forgot to wash and her favorite tee, faded and torn over the years of her refusing to let it go. After getting back to her lab, she set a machine over her notebook to take notes of her condition while she locked herself in a sealed tank. Not long after the locks engaged, the changes started. Her stomach was the first indicator of her change, making her wince in pain, clutching it and rubbing it for relief. She decided to flex her anus, maybe it was gas that she was dealing with; but after trying a few times, nothing came out, not even a tiny squeak of a fart. All that exertion caused her to sweat, and the stomach pain didn’t stop. The sweat caused her fur to get damp as she started to flex her ass and vagina, hoping for some kind of relief from the pain. And then, she smelled herself. She smelled like a rotting corpse and felt like she was being tortured. After tearing up over her stomach, she finally got some relief in a large, wet belch that lasted for a whole minute. She watched her stomach balloon out, casually letting out the nastiest sounding burps anyone had ever heard. She smelled the air, and even her breath was rotten. Then, the unexpected happened. She started to grow in size. From a tiny (midget-sized) mouse anthro to a normal person sized rat anthro. Her tits grew from B cups to C cups, and her hips ballooned out too, giving her a hefty wagon with beach ball sized cheeks. But her transformation wasn’t done, was with her growing ass came all the smells. She started laying some nasty farts into her sweatpants, knowing that they were there in case her ass had more than just farts waiting, and rubbed her stomach while she did. She felt like her insides were having a circus performance, because not long after, she felt the need to pee, and so she did, while still stinking up the sealed tank. Just then, her fetish brain got an absolutely vile idea, and waited until her sweats were soaked thoroughly with piss. She then, while still blowing ass (her farts started to get a little wet), did a handstand with her hands in the puddle of piss on the ground and let gravity carry the stream down her stomach and down her face and hair. She was surprised out how much was coming out of her, she had never peed so much in her life. She giggled as she felt it trickle down her stomach and neck, watched as it flowed down her hair, even tasted a little bit of it and almost lost her balance at how strong it was. After giving herself an impromptu golden shower, she stood back on her feet, squat down, and grunted hard as she felt a turd pushing through her intestines. She wouldn’t wait long before ass juice painted her gray sweats a slightly brown patch on her ass before the worst smelling dung slid out of her ass. Best part of it was, it was semisolid, just the way she wanted it. She just kept pushing more and more shit into her sweats as her body began to emit visible stink lines to the point where her fumes emitted a cloud around her. After a few more pushes, she had gone past the point of sagging and has let some shit fall down her pant-legs and onto the floor of the tank, where she then steps in it, wiggling her toes in it. The sweatpants original color is unrecognizable at this point as her last log comes out, shit spewing from every possible hole, as she falls flat on her ass and spreads it all around. She makes shit angels out of the puddle of shit and piss on the floor, her morality slipping away faster and faster. She then falls asleep in the pile of muck, cumming a few times in the process.
Marina wakes up disturbed, Mina is nowhere to be found. She goes and checks her phone to see if she missed a call or anything, but no one has even tried to call her. She tried calling Mina, only to be put straight to voicemail. With no other options left, Marina would have to travel outside, wearing nothing but a curtain (still no clothes that fit her lower half), and searching around for her. Once Marina did check outside however...
