As Jen tried to pay attention to the teacher and vet, she could hardly take her mind off her cocks. All because of that curse...wait, the curse! She leaned closer to Sarah and whispered "Transform or dare." Sarah turned and looked back for a second before rolling her eyes and ignoring Jen. After a minute passed, Jen turned the girl around. "I asked you a question, and since you didn't answer, you get both." Jen spoke softly to not draw attention.
"For your transformation, you will be able to grow as many pussies needed to fit as many cocks as you can into you at once, depending on who you're fucking. You will grow a massive fetish for massive horsecocks however, so who you will be fucking is me, always. All of your pussies will always remain very tight. If anyone cums in you, you will absorb it all like a sponge. To keep you from drying out, you will always be wet, and anytime you cum you will get even more wet, keeping whatever meat pole you're riding soaked. No one will think this is odd. Sarah looked half disgusted at what she was hearing. "For your dare, I dare you to use the curse on someone else."
As soon as Jen stopped talking, Sarah dropped to the floor and began to stroke and like at Jen's shafts. The quickly hardening cocks were all easily fit into Sarah's 6 pussies, and soon Jen lifted the girl off the ground as the cocks extended to their full length. That's when Jen realized that she hadn't specified if she was considered 'someone else' to curse.
