Mark felt fucking weird. One minute he had been pulling out the oil pan to repair the gasket. Then the tingling had started, this weird fucking tingling. And it wouldn't stop. He pushed himself out from the car and stood up, wiping his greasy hands with a rag, and scratched his ass. Then... he realized something was wrong. Very fucking wrong.
In sudden shock, Mark looked down at his baggy blue coveralls. Stained with years of grease, they usually hung unflatteringly off his beer gut. But his gut was smaller. At first, he thought maybe he had lost weight, but that was fucking stupid. People didn't just lose weight under a car. To his further concern, something felt off about his dick. He slipped his hand through the pocket in the coveralls and grabbed his dick. And then panic set in. Mark frantically slipped his greasy hand down his shorts and felt his cock and balls.
They were TINY! He prick felt like half of it's normal self, and his nuts were barely the size of grapes. He screamed, hearing the girlishness in his voice, and grabbed his throat in horror. Without further inspection, he bolted across the yard and ran towards the front of the house, he fumbled with the doorknob, seeing his more slender hands, and now sweating in fear, he ran straight upstairs, ignoring June passed out on the chair with the TV blaring, and locked himself in the bathroom.
A quick stripping later, Mark's fear was founded. Standing naked in the mirror, he stared at himself in teary-eyed disbelief. His face had lost its rough stubble and smoothed to silken perfection. His hair, meanwhile, was now down to his ears and turning from salt and pepper black to much lighter blonde. As tears streamed down his face in fear, he watched his still slightly plump body losing heft quickly, while his dick was now down to a tiny stub of itself and his balls were practically gone.
"What the fuck is this?!" Mark screamed at the mirror, crying more as he heard his voice raising in octaves. Suddenly, a pulling sensation on his chest alerted him to new troubles, and to his horror his tits began to push out. He was losing body hair fast, his skin was smoothing, and he was now only a little doughy as opposed to just middle aged fat. He screamed, a girly scream, trying to press his tits back in as if that would help, but they surged forth under his hands, turning into familiar but alien female breasts. A C cup or more? Now Mark stared at his teensy dick as it flattened into his smooth groin. He watched in wide eyed, crying, frantic horror and waved his hands in front of him with almost female franticness as a slit opened between his legs. Revealing a new clit. This deepened and developed until he had a clear virgin pussy, pink lips and slash and all.
He lost it now, sobbing into his hands as he now grew slim and dainty, feminine, losing his muscle, and his tits grew bigger and bigger, like inflating balloons.
"Nooo...." Mark took one look at herself in the mirror and broke down again. There was still stains of oil on her hands. And while she was still tall for a woman, she was a fucking woman! Mark looked over herself, her tall blonde body with big tits, and while a part of her loved seeing a sexy big breasted woman in the mirror, another part of her was freaked the fuck out. This wasn't right!
"M-Maybe..." Mark sobbed. "Wash it off." Her mind wasn't clear or thinking rationally. She hopped in the shower, ran the water frantically, and soaked herself. Soaping and scrubbing frantically hoping the girl would wash away. It didn't. And Mark fell to her knees and then her pert ass crying frantically under the water, arms pulling her legs close, sitting on her pert shapely ass, big tits squished into her chest, and she wept.
