Mitch, with a bemused smile, watched Karissa's ears flop around a bit, but remain stiff and straight. Again, the amulet perceived Mitch's wish, which was now coming to the surface. And the amulet glowed again.
Karissa still scared of what just happened, started felling constricted by her clothes. She kept growing until she was forced to take off her shirt and jeans leaving her with her bra and panties.
Mitch was still somehow excited by his girlfriends changes. She hasn't still noticed that her skin roughted and her hair shortened.
Meanwhile, Karissa started feeling an emptiness sensation on her chest, like if there was a thing or two missing, there also was an extremely tightness in her panties. This one forces Karissa to looked down in horror just to see her bra empty and instead her soft chest she(he) saw finely defined pecs. The she looked at her panties with disgust, already knowing what to expect. But what shee saw exceeded her expectations. Her panties were only supporting her new testicles while her new penis had stretched till reaching donkey proportions.
"What the?" said Karissa, just in time to discover her (his) adam's apple.
For mitch this was fun, he was feeling sorry and, yet, amused and excited. What's next?
