The walk to Mary's home felt like an eternity.
Kristen was doubling over every other step as her body was pushing against her clothes, her belly getting rounder and fatter by the minute, her members becoming thicker, and a pig's tail poking out of her pants through the torn seams. Her shirt ripped appart along the way and all she could do was trying to hold its rags closed with her short stubby fingers to keep her breasts from spilling out. Fortunately it was night-time and the streets were desert.
As she passed the doorstep's, another sudden body swell tore Kristen's bras appart, which fell on the floor. Massive breasts jiggled out of the remnants of her shirt - not just one pair but also several smaller ones, which looked more animal in shape. Her hips and belly were huge. She looked like a pregnant sow.
As Mary pushed Kristen in the living room and closed the door, another sound of ripped fabric resonated, and Kristen shook off her body the last pieces of fabric that covered her - pants, underwear, nothing was left but pieces on the floor's tiles. Naked, she stepped out of her shoes, only to reveal stubby feet that were slowly turning onto hooves.
Kristen was losing her balance; she walked awkwardly to the couch, her whole body jiggling along her motions, and let herself fall back, her breasts and teats rested against her body and heaving at every breath.
"Shze Hooman Fvial, Mehry" Kristen uttered with difficulty as her mouth and nose looked more and more like a porcine snout.
Mary ran and grabbed the Human vial to bring it back; as soon as it was in her hands, Kristen took a thirsty gulp from the small bottle. Her transformation stopped and started reversing, her face turning human again. Soon her body started shrinking in size...
"How can I stop that now, I just want to find a middle ground!" Kristen protested, holding on to her huge breasts.
"Uh... Try some of the Pig vial again? That's how I did it, though I think drinking too soon can lead to unpredictable results..." Mary said hesistantly.
She rummaged through her pockets to find the Pig vial. She started sweating cold when she realized she had forgotten some of the bottles at the party, in the bathroom. She did find the Pig vial, as well as the Cow, Mermaid, and Hyena ones. She couldn't remember what the others were.
"Here" she said, and Kristen took the Pig vial, drinking another generous gulp.
