Jen an Clair far removed from the cares of actually worrying about school headed off to the bathroom at the farthest end if the building. The bathroom in question was so out of the way that it rarely got used. The whole school knew it to be a safe haven to skip classes, hook up, or ride out a buzz. It was likely they wouldn't be disturbed.
When they arrived the hydra-naga that was Jen and Clair were elated to see an unused garbage can placed in the corner, freshly changed for the day. They removed the flap lid and all 4 bodies encircled the empty can. Unceremoniously all their pairs of breasts and heads became coughing up the small white pills into the receptively, in moments the bin was half full.
"Jen' Clair? You alright? your not blowing chunks or something are you.?" Came a sluggish voice from behind them. One of the bodies turned to face the speaker while the others pushed the can out of view.
The speaker turned out to be Mitch McDow, easily one of the top 3 if not number one pot heads on campus. In circles Mitch claimed to have a hook up for just about anything fun and non life threatening. Molly, LSD, shrooms, and every bud imaginable. How he managed to never get caught was anyone's guess. Even now the skunky smell of burning hemp began to seep into the bathroom.
Jen and Clair quickly formed their plan with their combined brainpower before having their other bodies pile pills from the can into their concealed hand and starting their act.
"Hey Mitch, yeah, we were hacking." Jen began.
"A friend gave us this psychotropic and we thought we could handle it..." Clair picked up.
"But we didn't take it too well." Continued Jen.
"Rad! I mean, I hope your alright." Mitch cheered before lowering his tone to concearn.
"Yeah, we're fine, but were not taking anymore of these." Jen said, revealing her hand filled with pills and turning to throw them out.
"Whoe!" Mitch shouted "hay, if you can't take them why not let me have them, no sence throwing out a good time, right? Ill pay you back for them, maybe a trade? You know I got hook ups on like, whatever your into. Probably find you some good mutant strangth stuff." Mitch encouraged.
"Mutant strangth?" Clair asked, clearly surprised such a thing existed.
"Yeah, totally I can swap you some. Take me a bit to get ahold of but I can"
Jen relied quickly "sure, deal!" Not really caring about the trade, but rather putting more unknown pills into circulation.
She dumped the pills into his hands. Mitch quickly produced a small plastic bag from his pocket. Something Jen or Clair were not surprised by.
"Sweet!" He mumbled taking a pill for himself and popping it in his mouth. "English class is always such a drag, hopefully this will pass the time."
Jen and Clair watched as Mitch's thin stringy form swelled in the bathrooms small space.
His cloths burst off as his arms swelled with veiny muscles to the size of trees! Each arm becoming as long as he was tall.his fingers fused into two large digits as big as eggplants and he quickly adopted a stance of walking in his hulking arms! His chest broadened to 4 times its size, on scale with his massive arms. Three bulging pecs dominated his torso with 2 inch long erect nipple. a never before seen 9 pack, that is 3 rows of three, covered his stomach.
His cock burst from his pants and along with his legs became limp but grew to 15 feet long as they grew to a foot thick and morphed into prehensile horse cocks.
His jaw grew three times its size as thick yellow tusks grew up from his face in a brutish grin. Each tusk reaching over his head and dominating his face. This last fact became less important as his eyes grew twice their size and merged into one large cyclopean eye
The girls were nearly forced put of the bathroom, their four hydra bodies and tail fighting for room with the hulking man that was now Mitch McDow as the final touch sprouted across his body. Thick carpets of hair dominated his chests, underarms, and crotch. The room now filled with not only the scent of pot but also excessive testosterone.
"Hang on girls, I gota release some tension." Mitch said as the pills made him horny and unaware of his TF having believed them to be just drugs.
Standing on his fists he arched his three cocks over the stalls and with what seemed to be the ability to ejaculate at will cam into the stalls, presumably into the toilets. That didn't matter though as Jen and Clair watched with fascination as thick white cum splashed onto the floor and seeped out under the stalls like the toilets were all clogged. Judging by how thick the overcharged testosterone fueled cum was crawling along the floor like portage, they probably were!
All the while Mitch screamed a deep bellowing bassy moan, head arched twords the ceiling only inches from his face. The girls took their chance and pulled the can and its contents into the hall and out of sight.
Minutes later when the bathroom was overflowing with cum, Mitch finished his release and turned, looking back at the hydra-naga Jen and Clair.
"Sorry there, you know how it goes, when you gota cum you gota let it cum. Anyways ill find you something fun in exchange for these." In his hand (yes he propped his whole body up on one arm) he held the baggy of pills.
"Or, if you like, we can do some kind of other payment." He raised his still dripping cocks into the air and with his one eye blinked at then, with his best suducimg smile his obscured face could put out. The body language was enough to pick up the hit though.
