Finally reaching the bottom of the emergency stairwell Marina pushed open the door, emerging into the alleyway that ran down the side of the office building. Walking was becoming difficult now as her strides felt more and more unnatural to her.
Marina only managed to got a few steps from the door before stumbling forward onto all fours, her two rows of growing tits wobbling from the shock. Discarding her bag she tried to stand but found she could not as her spine twinged and changed shape. The feeling reached the end of her spine and with a grunt she felt the nub at its tip grow out into a full tail, curling as it did.
Looking down past her slowly growing snout Marina saw her hands slowly begin to morph into trotters, a strange feeling in her feet informing her they too were changing. The sensation spread as she felt her arms and legs begin to change shape and shorten, with a loud fart she felt her ass jiggle as it continued to grow atop her changing legs.
Though she had been embarassed and horrifed by her changes only minutes before Marina alarmingly found herself growing increasing aroused, stinking juices ran like a river out of her vagina and backing up to a nearby pole to began to rub her sloppy slit up and down the poles length desperate for release. Eyes rolling back in her head she squealed in pleasure as the pink flesh of her vagina darkened and grew thick and leathery, her entrance now perfectly postioned for a pig.
Almost fully a pig now Marina's transformation was nearing its end. Enormously obese she panted as sweat dripped from her body, her huge, swollen teats swaying beneath her. She stunk like a beast, and increasingly was thinking like one, all embarassment now gone she had only one thing on her mind, she needed to breed.
