A momentary sense of embarrassment sent Percy on a scrambled run for the restroom and a look-see at what he knew might be trouble. His moving past other viewing patrons had a young woman see the building bulge in his groin, and she gave him a friendly squeeze.
The sensation of a squeeze about sent Percy into a seventh heaven. Grabbing with both hands to cup his building sensation, he staggered up the main aisle, across the lobby, and into the restroom and a toilet stall.
Muttering to himself about having been as foolish as not washing his hands after applying the Yak butter to his chest, he stood gawking down the length of his body, in awe, and horrified.
He most definitely had hair on his chest, but nothing like that prone to being a macho man. The hair was coarse to the touching, thick and becoming shaggy, beginning at his chest and trailing into his lower regions.
Brushing his hands through the hair on his chest, he felt the building pressure of an erection forcing its desired way out past the waistband of his Jockey shorts.
Percy stood in horrified awe, seeing a growing protrusion emanating from his groin and proceeding to add skin and new muscle to his bloating abdomen. A pointy pink colored shaft worked its way, building in length and girth until it stood erect and something profoundly bestial.
Fear of self, rapid breathing, and the spreading transition of a young manly body to begin resembling that of a Yak calf.
Forgetting he had as of then not yet washed his hands, Percy stood rubbing his face and sweaty forehead, causing more infestation.
Sweat and opened pores of his skin added to his discomfort as the Yak in him began to expand and take over his entire bodily form and functioning.
Nose holes swelled, becoming bovine like nostrils as his mouth joined into making him a very bovine shaped muzzle. He whined with feeling his face change, and ground his teeth hard, taking note that hey too were becoming quite similar to those of a grazing and bovine animal.
Anxiety caused more of his yakking it up to take a bigger control.
A sudden flushed feeling drained his strength as from his groin begat a building weight, his testicles swelling, and buttocks, thighs, and upper legs attested to living life as some bovine animal. The change swept down more, turning human heels into massive bovine hocks.
Percy let out what he would have expected to hear as a sorrowful moan, only it echoed the bathroom as one young male Yak bellowing his personal disgust.
Changing up and down, around and everywhere, the Yak self became the complete embodiment of Percy. He stood with his fore hoofs leaning on the toilet tank lid, while then fully formed hind Yak legs and bovine feet, cloven hoofs and shaggy hair stretched out long and lean.
The rugged sensation was beyond his ability to bear, and calling out like some bull Yak in rut, Percy stood with a very stout erection, and a movie house manager screaming for the pervert to exit the bathroom.
