As I look in the mirror, I feel a shudder run through my body. I look down, confused, and am surprised to see the shirt stretching, pushed outward by my growing chest. I look up at the mirror in shock. It's my face all right. But with a better tan. And stubble. And that thick neck. Those magnificent traps. The huge shoulders, filling the shirt till it's tight as a drum around them, leading down to massive arms, plump with power. My pecs, jutting outward magnificently, a pair of thick slabs of perfect beef. And because it's a v-neck shirt, the deep chasm between them is obvious. Thick nips poke downward, jutting out against the fabric, prominent and sexy. And sweeping lats, pushing out to either side, leading down to a tight, taut middle, with thick, brutal abs visible under the tight shirt, leading down to the belt, worn with use, but still hanging perfectly off of my hips. The jeans hug my ass now, my thick, strong glutes filling them nicely, leading down to strong thighs that push against the tough fabric, filling it with powerful muscle. All leading down to the big, over-sized workboots that came with the costume... this incredible costume.
I stare at my reflection in the mirror, in awe. I look like me, but with a huge, muscular body, packed into the clothes so tightly that every freaky curve of my new physique. I run my hands up over my body, noting distantly that even my hands are bigger. I lift the shirt up slowly, and give a low whistle of appreciation as I see the thick, powerful abs of my stomach revealed. "This is incredible!" I mutter under my breath.
