The room was filled only with the sounds of gunfire from Josh’s game until a quiet tear came from Megan’s shirt. The stitching around her shoulders were slowly pulled apart as they grew wider and rounder. The tears grew louder as her shirt slowly pulled apart, causing Josh to finally notice what was happening to her.
With a snap the laces of Megan’s sneakers burst and her feet tore through the front of the shoes.
Josh looked over casually at Megan, curious about the noise. He was shocked at what he saw.
“What the fuck!” fell out of Josh’s mouth as he watched Megan’s breasts swell larger against her shirt.
“Hey! Language, little guy,” she said out of habit, as her bra broke and released her massive tits.
Megan's midriff was fully exposed. Her new six pack tightened and thickened with power.
Josh stared in stunned silence watching his babysitter (and secret crush) grow larger by the second. Megan grew heavier causing her to sink into the couch as reached a weight in excess of 180lbs. Climbing out of the seat she inadvertently flexed her thighs and calves, causing the seams of her jeans to spilt wide around her swelling quads.
As she rose out of her seat Megan’s head continued to rise higher and higher as she stood up to a full height of 6’6”. A load tear sounded from Megan’s back as her shirt was literally pulled in half by her large lats and rock-hard shoulders. With a crack Megan’s sneakers exploded as her feet had become 5 sizes too large for the now tiny shoes. The remains of her sleeves fell to her feet as her baseball sized biceps and horseshoe triceps continued to grow. The torn and split tube top that was once Megan’s shirt was wrapped tightly around her chest causing her F cup tits spilt over the top.
With a physique similar to a heavyweight female bodybuilder, Megan’s surprise at her sudden growth was replaced with a profound curiosity about just how large she would get.
