The moment Keith’s fat clawed finger pressed the button there was another bright flash that blinded you again. After that you knew something was terribly wrong, even before your vision cleared up. You felt big in all of the wrong places, and empty in places that should have something there. By the time your vision cleared you saw Keith with a smug toothy grin from cheek to cheek, and that’s when you looked down at yourself although you were more afraid of what you’d see than not.
You now wore a flannel shirt like Keith, but with a faded green color instead of yellow, and you had overalls on as well but you felt nothing beneath that. Unlike Keith, you weren’t nearly as muscular but you certainly looked like you packed on a bit more than a few pounds fat beneath your shirt to accommodate for your lumbering body. Your clothes felt tight, not only like they were they pressing up against your stomach uncomfortable but your waist and chest as well.
"Damnit Keith you little...!" You snarled at him then paused once you heard the sound of your voice. That’s when you realized the pitch, while appropriate for your body, was no where near masculine whatsoever. You then noticed your abnormally wide hips, and the ominous emptiness between your thighs. Upon realizing this you slowly looked back up at Keith and said,"You didn’t..."
"Oh, yes I certainly did," Keith chuckled to himself,"I think I prefer my ladies more on the... hefty side now."
That’s when you felt a violent churning in your stomach, like you just went to a Mexican restaurant and decided to eat the biggest and most spiciest dish they had, but worse. On top of that your bladder felt like you just chugged a whole gallon of water just before you left home, and the flood gates were ready to burst. This had to be Keith’s doing, you knew it, but you couldn’t focus on that now as the pain of indigestion was so much worse.
"Urrgh! Fuck! Fuck! No! No! No!" You cried instinctively reaching down to pull your pants off, but then facepalming before desperately trying to unbutton your overalls.
"What’s wrong? Someone having bowel issues?" Keith asked, mocking your attempts to unbutton your overalls. You glared at him as you finally got the first button undone, but as you reached for the other one you felt your bladder give away, and your bowels opened involuntarily shortly afterwards.
"NOOOO!!!" You screamed feeling large, soft logs of shit empty into your overalls followed by even worse smelling diarrhea. You saw the yellow stain too, appearing in front of you and you covered it with your hands out of embarrassment as you felt the warm yellow liquid soak through onto your hands and drip down. The process didn’t stop for a few minutes and it eventually got to the point where you just gave up and let it all out. However for whatever reason the feeling of emptying your body waste felt relieving in a disgusting sort of way, and something about the smell seemed to almost turn you on. You still hated this feeling, or at least you think you did, and you wanted to shove every ounce of what was in your pants inside Keith’s smug idiotic face.
Keith then took a deep breath and sighed with a smile,"Ah, heh that’s quite the load you just dropped there sweetheart."
Keith took a step forward and you took one back only to feel your pants shift and allow a stream of piss and feces to run down your leg. "W-What the fuck Keith?! Is this some kind of sadistic revenge or something?! That was an accident I swear!" You growled at him then looked down at your body and bushed as you saw one of your new large breasts strained up against your shirt, and what’s more was that you weren’t wearing a bra so it was practically on display.
"Well, yes and no, I just wanted you to experience a bit of a kink I have, and as a you’d be a big beefy bear who’d lay down just as much shit as me," Keith said then he let out a bellowing laugh and sighed,"Though... the lady thing wasn’t intended. I think I accidentally pressed two buttons on this damn thing."
"Okay well, you gonna change us back or what?" You asked and Keith shook his head,"Not a chance, seriously why would I pass up on an opportunity like this?" Keith’s bulge grew a bit larger in his pants and your eyes were suddenly drawn down towards it and you blushed red as you saw it. You then felt a warm sensation between your legs start to act up, and you felt a wave of pleasure throughout your body.
"Uh... um..." You whimpered now feeling conflicted between your mind and your instincts, and Keith walked up to you and said,"You feeling alright in those clothes? Honestly they look a bit tight for someone of your... uh..."
"...mass..." You replied and Keith sighed,"Didn’t wanna straight out say it, but yes, although I girls with bottom heavy bodies."
You continued to blush, and occasionally your eyes darted from Keith to his bulge unsure what to even do in this kind of scenario. Was this just another idiotic prank of his turned serious, or did he have something planned? Either way he placed his paw on your shoulder and unbuttoned the other strap to your overalls and looked down at your body.
"Damn... got a couple of watermelons underneath that thing too... I’m not gonna lie, you’re turning me on right now," Keith said in a low seductive growl that made your heart melt, and your cheeks feel just as hot as your loins did.
"Keith I... You..." You stammered then Keith chuckled and said,"It’s alright I’m a seven foot tall muscular male bear, and you’re my six and a half foot tall woman who just came out of hibernation. We’re both dirty beasts with shit in our pants, and the power to change pretty much anything. If you’d like we can, you know, have some rowdy fun as we are, then once we figure out a way to change you back to a guy it’ll be like nothing happened. Although I’d still be fine with a family of cubs, but that’s all up to you."
You then watched as Keith unbuttoned his pants and let them drop to the ground with all of the nasty shit he dropped into it. His cock grew from a half mast 8 inches to 10 immediately after and his balls were the size of apples. Your loins burned with the desire to do what two unrelated members of the opposite sex do as the animal you were loved all of this. But you couldn’t just trust Keith after he did this to you... right? Whatever you decided to do you had to do it fast before Keith decided it for you.
