The liquid instantly burned a path through my throat and hit my stomach. It was a bit unpleasant but not painful. I could see the changes starting though, as advertised when I’d bought the product. My toes were starting to flatten and fan out in a thin membrane as scales quickly gained on my soles and heels. I was delighted to notice that the thin cartilage that the bottom half of my feet had become was the same colour as my hair. The scales, however, were a bit of a lighter red, coming close to a cute pink as they quickly claimed my thighs and my knees. I quickly undid my shorts and panties, sliding them down as the transformation went upwards. Didn’t want to ruin perfectly valid clothes, right? I turned a bit from the camera, shyly hiding my private bits from its lenses.
The changes were climbing up my hips now, having completely covered the whole length of my legs. It swiftly went back down again as I felt an irresistible urge to squish my legs together. These soon lost definition as they merged together in a single appendage that was unmistakably aquatic. A few seconds later, I lay there, a mermaid in the flesh. I flashed a grin at the camera, cheeks flushed with excitement.
The changes, though, weren’t quite done with me as I looked down at my hips with expectation.I could feel my whole body restructuring, my bones grinding and reshaping. It was a bit painful but relieving in an odd sort of way. It mostly felt right, the way it should be. The scales were going rampant, quickly covering my belly and chest and I had to remember to take off my shirt and bra before they were claimed by the potion.
My entire torso having properly been scaled in red, the next change was my neck as I felt the pinpricks pushing out from my skin and I laughed. The next reshaping was under-way. My whole silhouette was reformed, losing its feminine aspect. I could barely be considered human at all as my neck puffed out with flesh and bones, filling out a bit beneath my chin with muscles, tendons and bones. I looked down at my fingers to notice the membrane slowly eating them away as well as they lost definition. I could feel them lose mass and bones as they became flaccid and thin, my arms retreating into my body to join these new blazing red fins to my sides. I could feel other fins pushing out of my back and around the middle of my new tail and I sighed in delight. This was what I truly wanted.
