Jennifer got dressed quickly, ashamed of what she had almost done and horrified at the consequences of Johnny's actions. She could also feel Johnny looking at her in the reflection. Even in his dormant state he was still a horrible lecher and Jennifer could not stand to look at herself with the pervert watching her every move from within. The curse obviously hadn't triggered yet but she could still feel the triumphant smugness of her unwanted passenger.
She could hear Ariel timidly creeping out of the bathroom and decided that confronting her woulkd only traumatize the poor girl further. They both had history class next period so there was plenty of time to find out what the curse had planned. She quickly hurried to avoid being late. Little did she know every second was ticking down to a time bomb.
Shortly after Jennfer took her seat Ariel entered the classroom, just beating the bell. She seemed normal enough if a bit spooked still. Before she could sit down though the ten minute mark on the transformation struck. Jennifer groaned in pain, falling out of her seat in agony. Her stomach pulsed and writhed before swelling out like she was pregnant. Her stomach continued to bloat and swell, crawling from beneath her shirt like a fleshy amoeba. Her belly button folded in on itself forming a makeshift mouth. "Freedom!" her stomach exclaimed in Johnny's voice. The whole mass detached from Jennifer leaving her gasping on the floor, her midsection smooth and missing a belly button. The mass took on a vaguely human shape and began to laugh but the voice jumped up an octave. Ariel squealed in fright and pain as the front of her skirt tented out. The blob that was Johnny took on a more feminine shape as Ariel's breasts deflated like opened ballons. The teacher seemed oblivious to the transformation but the students stared in shock.
Ariel began to bulk and swell, losing her curves to a beer gut and muscle. Johnny's eyes opened on the vaguely girly mass and the simple bulges of fat on his chest grew nipples that quickly plumped into perkiness. As Johnny began to grow hair Ariel's hair lost its color and lust, becoming grey and lifeless.
The transformation continued until Johnny stood naked as a perfect replica of Ariel and Ariel looked ridiculous as a middle aged man squeezed into the clothes of a teenage girl, every movement threatening to break a seam.
