Jen sat at the table aijda thinking about what to do with the pill, joining her mother who was already waiting for breakfast. The maid delivered breakfast to the table and went back to her duties in the kitchen.
Before I could start eating Jen's mom's cell phone rang, so she left the table to take the call.
Jen took the time to put the pill in her mom's coffee, which she took without suspecting anything after ending the call.
As soon as Jen's mom had had her breakfast she started acting strangely, standing up and saying she had to go to the bathroom, but after she took a few steps her pants were immediately ripped off due to her lower half of her body quickly stretching, her legs splitting into 4, her joints shifting as her feet turned to hooves, short brown fur covered her lower half and a tail grew at the base of her spine.
Jen couldn't take her eyes off her mother, who was looking at the horse body that was her underside, totally surprised after she had become a centauress.
"What the hell happened to me?" Jen's mother yelled. With the yell Mary ran to the dining room, where she stopped in shock at what she found.
"Are you okay mom?" Jen asked
"And of course I'm not fine. Did you see the lower half of my body turned into a horse's body, how could I be okay after that?" Jen's mom said
Jen didn't know how to respond, especially knowing she was responsible for that, Jen didn't know how to respond, especially knowing she was responsible for that. She then noticed that something had moved under her mother's horse body, but in her angle of view she couldn't see enough to make out what it was.
"Mom, it looks like there's something under you." Jen said
"I had already noticed. I can feel something pulsing under my horse part, but it's a totally unfamiliar feeling to me and I can't think what it is." Jen's mom said
"Let me see for you." Jen said and knelt down next to her centauress mother, being amazed to see that the thing moving down there was a big hard horse cock that pulsed beneath her mother. She noticed that her mother also had bulky balls, so she quickly jumped up to look at her from behind and confirm that there was no sign of a vagina there. "Mom, you won't believe it but the thing you feel pulsing down here is your cock, and you are hard. Your lower half has become the body of a male horse." she said
"What? It can't be, this can't be happening to me and…I'm sorry but I really need some privacy." Jen's mom said, blushing not only knowing that she had a dick and that it was hard, but that her daughter had seen it. She was so embarrassed that she wanted to hide in her room, so she tried to run, but she wasn't used to getting around with her new body and failed miserably. Mary was standing without reaction on the way and when she tried to dodge, she lost her balance and ended up falling to the ground, slipping a little after the impact.
Mary, seeing her transformed mistress fall and slip towards her, tried to escape being hit by turning around and trying to run, but she wasn't fast enough and Jen's mother's horse cock ended up inside her uniform.
The two tried to get out of each other quickly, but they messed up and Jen's mother ended up cum inside her maid's uniform with the stimulus received.
