Jen knew she couldn't drink cum from her mother's tits, but she was still hungry. She decided to blow her brother while she decided what else to eat, the horse eagerly letting her suck him off. She swallowed as much of it as she could when he came but got showered in it. The cock got pointed at her mother and she absorbed all the fresh cum from the horse, making all her tits swell up to four times their already large MM size. When he finished cumming Jen licked the last drops out of his urethra, before standing up and going to her mom. "Hey mom, transform or dare?" In her mother's new state she didn't answer, in bliss from all the cum she was just showered with. "No answer means both. I transform you so that eating your pussy will taste great and make people feel full. Your pussy will now also emit pheromones that makes it hard from people to stop drinking from your tits, and they won't affect me. You dare is to dare me to eat your pussy."
Jen's mom moaned as her pussy suddenly squired, becoming extremely wet and smelling very sweet. Jen's mom asked her the question and dared her to eat, so Jen got down on her belly and ate her mom's pussy like it was the best thing she ever tasted. She took a break part way through to call two of her friends over. It wasn't long before they came, got trapped sucking her mom's tits, and got sucked in to become more tits. Her mom stood with her soaked pussy and four rows of EE tits, pinching as many of her nipples as she could. Jen had her lay down where she could eat her out and get fucked by the horse before calling her brother over for a long fuck session.
