"Who the hell are you?!" I shouted as I dropped my bags to the ground, ready to fend off this intruder, "And how the hell did you get into my apartment?!" The naked woman jumped at my intrusion, spinning around with panic in her eyes as light lanced from her fingers. I didn't have time to notice the bolt of energy leave her hands before it struck me in the chest, causing me to fall to the ground in pain. "Oh shit!" She said, covering her mouth, "I'm so, so sorry! It's me, Mark!" I looked up at him, seeing the strange similarities between her and my friend before a tingle overtook my body.
My arms snapped to my sides, causing me to fall onto my face and chest, knocking the wind out of me. "What's happening to me?" I cried in a wavering voice as my arms melted into my torso, leaving me without any arms. My jaw felt loose, the sensation only growing as my mouth was forced open, unhinging like a snake about to devour its prey. The woman, Mark, stared at me in shock as my face lost its features, consumed by my ever-expanding mouth. "Oh my god, oh my god," she kept saying, hands over her mouth.
Dark gossamer patches appeared across my body, replacing my skin with its textile nature slowly but surely. The tickle of the consuming wave of black had me reeling in concern; the feeling of my very flesh turning into what seemed to be fabric was beyond terrifying. I felt my body stretch and contract, my very being literally restitched and hollowed out. My gaping maw turned into an elastic band that held the only opening of what I had become. Without any more fanfare, I crumpled to the ground in a heap, a pair of nylon stockings devoid of any sign of life.
"No no no!" Mark muttered, picking my body up with pinched, delicate fingers, "I'll fix this! I swear!" She looked down at herself, realizing she was still naked. She stared at me with remorse in her eyes. "I'm very sorry about this," she whispered to me as she spread my mouth open and slid her legs in, stretching my new body to its limits. I would've groaned in ecstasy had I still had the capability, but I instead just bathed in the bliss of being filled by the shapely legs of a woman, fulfilling the purpose my body was designed for.
She snapped my elastic band around her waist and looked at herself in the mirror, "I'll turn us both back! I swear!" Her words were lost on me as I swam in euphoria, my mind already willing to accept my new life.
