Ty thinking quickly made a wish swapping with her momentarily. The 4’11” brunette woman slowly turned around with a cold indifference.
“I’m not your mother Steven.”
The boy’s look of confusion became absolute terror as her form began warping and morphing before his eyes becoming muscular like him her clothes ripping as her chest and arms outgrew her dress.
“Mommy you got big like me!”
The woman grinned as her face broadened her chin and jaw becoming wider as hairs began to sprout from it and her eyebrows thickened het body hair continued to become more coarse and dark biting her thinning lips flexing before the muscular boy Steve looked on in fear at his (mother’s) arms got harrier.
“Something you like ya little shit?!”
The ripped house dress fell from her muscular body taking the opportunity to do a double biceps pose exposing dark bushy pit pubes leaving her in a bra and panties Steve wanted to run or look away his mommy was acting strange. The hirsute muscular woman removed her panties as she began growing a thick snatch thatch that began traveling up to her navel and traveling down her legs with a thickening dusting of coarse hairs. Sliding off her panties before the crying Steve exposing her furry vagina was almost too much.

At last ty freed Steve’s feet allowing him to scramble to his room as the ty impostor mom bellowed after him
“I love it when they play hard to get”
