The suit on the hanger was bulky and gray. Brad unzipped it and felt the interior lining. It was soft and warming a way that was a bit unsettling to him. A ropy tail hung down between the suit’s large asscheeks. A full head mask accompanied it, complete with floppy ears and a long trunk. “What is this, some kind of costume?” Brad asked ashe examined the back of the costume. The suit’s hips were considerably wider than Brad’s. “Is this thing going to fit me? I mean, it’s pretty big…”
The voice came back over the intercom. “Don’t worry about that, just put it on, please. The mask, too.”
Brad shrugged and stepped into the suit. It fit him snugly as his feet slid down the interior. He tugged it up around his waist and slipped his arms inside. He slid his fingers into the gloves and could almost swear the lining quivered a bit. The weight and bulk of the suit gave him some trouble, and he struggled to pull it up over his chest and shoulders. When he finally got it on, he could see why. Enormous breasts hung down over a large belly. “Ugh...is this really necessary?” he groaned.
“Yes, it is. Can you put the mask on, please?”
“All right, whatever.” Brad pulled the mask down over his head. The ears and trunk flopped limply. “I feel ridiculous in this thing.” His voice was muffled by the mask. He fumbled around back for the zipper, but couldn't feel anything through the suit gloves. “How am I supposed to zip this thing UMFF!” Suddenly the zipper closed itself and the suit sucked up against his skin as if it were vacuum-sealing him inside.
The suit lining came to life and he could feel it squirming and sticking against his skin, pulling at him from all directions. His skin tingled, burned, and went numb. His vision blurred for a moment and he felt the pins and needles of sensation returning to his skin. The blurriness resolved and he could feel air against his body again. The room looked smaller somehow. No, not smaller...he was larger. He looked down at his thick gray hands and saw tusks and a trunk dangling down between the breasts that hung heavily from his chest. It raised up in alarm as he realized that he had somehow become this...thing.
“Holy shit! This…” He went to examine himself in the one-way mirror. “This is me?” His voice had shifted to a husky feminine tone. He felt his new trunk, all the way from his face to the very tip. “My face...my voice…” He hefted one of his breasts up. The wide areola crinkled and the thick nipple stiffened, practically aching to be touched. A flush of arousal bloomed in his belly and between his legs as he gently squeezed and fondled his breast. “Oh god, if I have tits now, does that mean…” He reached down past his belly and gulped in hesitation before probing between his legs. His fingers found puffy labia and a damp cleft. He twitched and gasped and his tail lifted involuntarily when a finger brushed against his new clit. The scientists behind the window scribbled notes furiously.
“Fuck...How can this even be real?” He, now turned she, turned and looked in the mirror to examine her broad hips and her thick ass and thighs. “You've made me some kind of elephant woman freak!”
Behind the mirror, the scientists finished making notes. “Okay, this one sort of fell into our lap and we didn't really have the experiment planned out. What’s the next phase? Did we want to test command words? Initiate interaction?”
