The tingling electric hands returned, brushing the inside of his thighs and rubbing against his ass. He felt his balance shift as his hips cracked out.
His abs strained with exertion as his stance widened, driven by hip bones that were 50% wider than they'd been just moments before. As the sweat flowed down the muscular frame, it tricked onto legs that warmed and grew shaplier, with warm fat filling in his thighs.
His butt began to push out even as the base of his spine cracked, thrusting his ass out further. As if to taunt him, the hands gripped his muscular, round ass and kneaded it.
Watching over his shoulder, eyes wide with horror, as the twin muscular glutes flowed outwards, blossoming into two oblong female buttocks, fat flowing outwards even as muscle receded. Pull... two soccer balls. Stretch... two small watermelons. Quiver -- two large watermelons!
As the change slowed, the hands insultingly gave his large new ass a smack, sending the fat jiggling.
He had to stop this!
