Shortly after Samantha returned to her room to study, there was a ring on Gemma's cell phone. She had received a message from her boyfriend, Isaac, saying that he had just come home and would like to see her. He played for the school's football team and had gone to play against a college in another city. Upon learning that her boyfriend was back, the blonde fixed her hair as fast as she could and went to his house, which was just a 5-minute walk.
On the way to her boyfriend's house, Gemma started to feel discomfort in her crotch, but she decided to wait until she got to Isaac's house to see what it was.
Shortly after Gemma arrived at her boyfriend's house she rang the bell and was attended by Sophia, Isaac's youngest sister.
"Hi Gemma, come on in. My brother is finishing dressing and will be coming down soon, we just had dinner." Sophia said
Gemma accompanied the girl to the living room, where the whole family was gathered. Isaac's parents and their four children, Margaret was the oldest and was a teacher, but not in the same school where they studied. There was Flora, the couple's second daughter, who was recently graduated and made her living as a youtuber. Isaac, who had just arrived, was the third child and the only male, being two years older than Sophia.
Gemma got along very well with the whole family of her boyfriend and with the reception she had she almost forgot about the discomfort between her legs, but as it got more intense she excused herself and went to the bathroom to see what was going on. As soon as Gemma entered the bathroom, she took off her skirt and panties shortly thereafter. She was surprised because the whole area of her crotch was black and had a hole there, to make matters worse, her vagina had completely disappeared and she only had black, loose skin in place. Realizing what was happening, she almost screamed, but stopped because she didn't want to be found like that, especially when a pillar of meat came out through the hole in her crotch, which she recognized as a horse's dick. Her new member stopped her sheath revealing her erection, at which point a pair of spheres fell on her loose skin, which were her new testicles going to the newly formed ballsack. Before Gemma fully absorbed the transformation she had just undergone, another hole opened up near the base of her dick, from which a second growing horse dick emerged and, when it reached the size of the first, her ballsack grew giving space for another pair of testicles. Her transformation was not yet completed as more horse sticks continued to grow on her, and for each dick that grew another pair of testicles descended on her ballsack. In the meantime her ass grew, her anus puffed up to make an equine appearance, and a tail grew on her. When her transformation finally ended she had a long horse tail the same color as her blonde hair, even though she didn't have fur, her ass was definitely equine, and she had a total of ten 17 inches hard horse dicks between her legs and 20 testicles inside her new ballsack.
Gemma didn't know what she could do in this situation and the bottom half of her clothes would obviously not fit her anymore.
