After school.
Alex and Katie showed up to Jen's house, they all were excited to be there.
"So, Jen, how was your swimming class, I heard some rumor about that." Katie started. "Tell us all the dirty details."
"Well, you know. It was a normal swimming class. Except that I found out that the girls' nude body makes me hard, and I can only change my suit, and jump into water asap, and finally cum in the water, and made everyone's clit grow a little." Jen said, with a blush on her face.
"But, your crotch doesn't looks any smaller, in fact, it looks bigger for me." Katie reply.
"I agree." Alex assented.
"Well, I met Chris after girl's swimming class, and we were so horny, so I just blow him, and..." Jen said as she looked down at her now 10 inches cock tented skirt. "That's what I ended up with." She said, looking at her crotch." How about you?"
"I've got nothing interesting to tell. But I am really happy to have a small cock, it feels better than before. And you know, I think I was just having a bad day when we meet, but I think I'm OK now." Katie said, and then looked at Alex. "How about you?"
"Nothing, I guess I've hiding well." Alex said as he looked at them.
"And, you guys now know why Katie have 1 inch cock, and Alex's cock got smaller. Right?" Jen looked at Katie and Alex, before she said.
"Yup, indeed." Katie said, looking at Jen's cock.
"I am sorry Katie. I didn't mean to." Jen said as she looked down at her own huge cock.
"It's OK." Katie said as she looked down at her own tiny cock. "I am still happy with it. I guess I'm just a little jealous." She said as she smiled.
"Yeh, I'm reluctantly acceptable with mine, too." Alex said as he looked down at his 7 inches cock. "So, Jen, I know you're not going to like this, but we need to talk." Alex said as he looked at Jen's 10 inches cock tented skirt.
"What?" Jen replied. "Can't wait?"
"I'm not talking about sex. Look, I assume we all already know how to fix this." Alex said as he looked at Jen's huge cock.
"I don't want to fix it." Jen said as she looked down at her cock. "I like it like this."
"I know you do, but I really don't think you should be walking around with that." Alex said as he looked at Katie's tiny cock. "And I am sure Katie doesn't like this." He said as he looked at Katie's face.
"Look, I don't care about having a tiny cock, it make me feel better, but I know Alex do. MAN, just care about size." Katie tease a little. "But I agree we should try to fix it." Katie said as she looked down at her tiny cock. "I mean you two should try."
"Well, what do you have in mind?" Jen asked.
"It looks like everything is caused by you, Jen, every time you cum on us, we grow cocks and yous shrink, and every time we cum on you, we shrink and yous grow. Do you have any ideas." Alex questioned.
"I don't know, I can't do magic or something." Jen reply.
"It may not be magic, maybe you've get cursed?" Katie said.
"Oh, you mean 'Transform or Dare', Katie? Don't be so silly, everyone knows it's just a bedtime story for kids." Jen replied, unconsciously met the conditions for the curse to be triggered. "I can't believe you even think it's real."
Katie and Alex looked at each other, then back at Jen.
"But, what else could you explain all this? If it's not magic nor curse." Katie questioned, as she felt a strange sensation, met the final trigger to be cursed.
"Come on, Katie." Jen replied dismissive. " are you saying that I can transform you into ...
