"How are you holding up back there?" My friend turned owner asked, pulling up her skirt so I was revealed. Had I the ability to communicate, I'd tell her that I wasn't doing well. Between the heat radiating from her ass and the sweat that my cotton skin kept absorbing, I was in my own personal hell as her pair of panties.
When my girlfriend brought home a transformation remote, we both were quite excited. We both had our own personal fantasies we wanted to play out so we decided to why not do both at the same time. My kink was catgirls, strange I know, however, it was what I wanted so when she agreed I was ecstatic. Using the remote, I typed in my settings and pointed it at her, pressing the big button. Immediately her ears shifted from the sides of her head, elongating and reattaching to the top before growing a thin layer of fur the same color as her hair. Then her spine extended as a tail sprouted, punching a hole through her underwear. "Dammit," she huffed, "This was my favorite pair." Her pouting ceased as an idea struck her. Typing into the remote, she pointed it at me and blasted my chest, starting my transformation.
Immediately I felt the effects of the remote's influence as the hair on my skin began to prickle before fully disappearing. My skin took on a much paler tone until it was as white as the undyed cloth it was becoming. My arms linked in front of my chest, joining together. I was forced to the ground as my legs bent at an impossible angle, connecting to my combined arms. My entire body started to flatten. I was losing all my features as my body became a uniform fabric material. The transformation finished as nothing but a pair of simple, cotton panties lying on the floor where I was.
Feeling her pull my body up her soft thighs until I was wrapped around her fat ass filled me with alien sensations. A mix of pleasure and humiliation filled me as I felt her tail flick, brushing my skin. She pressed her hands into me, squishing my body into her doughy flesh. Ecstasy coursed through my body until it was rudely interrupted by two words, "Oh Shit!"
It turns out we never tweaked the original settings on the remote. For some reason, the remote's default settings had the time limit set to forever, and with no way to undo the changes my girlfriend was trapped as a catgirl and me her panties. So that's why she was currently asking me how I was doing because, in an effort to not leave me to my thoughts, she wore me every day. It had been a few months but the company that sold the remote had yet to respond and until they did, I'd have to get used to being wrapped around my girlfriend's ass.
