Ben quickly ducks out of Bills line of view, where he sees Martha changing Clothes..
"None of those will fit you soon Martha.."
Ben mumbles a spell with his hands pointed at Martha who is wearing a new dress when she feels something tingley over her body..
She strips naked and watches in awe as her slit shrinks to small(er) sizes and her body slowly begins to thicken.
At first her D cup Boobs begin too recede back and become a more square shape.
Then her stomach slowly rumbles and becomes a perfect 6-pack abs, whilst her bleach blonde hair recedes up and becomes a dusty blonde.
Her slender legs are ballooning out into thick muscles,but she freaks out when she looks at her groin!
Her now tiny hole is pushing forward into a Mushroom shape, forming a penis shape, slowly growing to a good 7" flaccid.
The whole ordeal has made him feel weird.. but when he looks in the mirror, his penis becomes erect at the site of himself, Then she realised that she likes MEN!
Bill knocks, and Martin begins to want to ease his erect, throbbing 12" dick.
