She followed her sister’s instructions and listened for the new transformation.
Jess didn’t waste any time and said, “You will only have one set of legs and your libido will be normal.”
Jen was overjoyed by the words, but didn’t have an opportunity to celebrate before her sister added a new condition.
“Also, your tongue will turn into a dick whenever you’re aroused.”
“What the fuck Jess!” Jen yelled.
“Serves you right for what you did to me!” Jess replied with a scowl.
Jess could see how angry her sister was. “Fine... You can control when it turns into a penis... Happy now?”
Jen conceded and said, “Thanks. I guess. I don’t really want it but at least I won’t have to worry about spitting up a boner in the middle of class.”
Left Jess replied with a heavy lisp, “Yer thellin mee...”
Jen couldn’t help laughing at the mental image. Jess wasn’t happy about her cock tongue but the laugh was contagious enough for her to join in. As they laughed, Jen felt her lower body tingling. Her legs began to fuse. As they merged and her waist shifted, the two skirts fused back into one.
Apparently the clothing aspect of the curse stuck with her. The panties on her right groin loosened as her body changed. Jess had pulled off the left pair when she helped her masturbate. Jen spotted it nearby, but was surprised to see that it was only half a pantie, perfectly cleaved down the middle. Her transformation ended and she lifted her skirt to see if everything was OK. Only one set of legs extended from her single waist. Between them, a single pink slit. The only thing unusual was the half-pantie that hung loosely on her right leg. It wasn’t doing anything to cover her groin, so she pulled it off and tossed it aside.
That had been one of her favorite pairs, but it was a small price to pay considering the situation. As she looked herself over, she realized that her thoughts weren’t stuck on sex. Jen looked up and noticed that both of Jess’s heads were turned away.
Jen dropped her skirt then stuttered, “Oh, sorry... I just needed to see...”
“No, no... It’s fine, take your time.” Jess replied with some sarcasm.
“In fact, let me know if I can help out. Since I grew this cock, I’ve been compelled to want to touch your pussy...”
Jen apologized again, then after a moment of silence Jess said, “There’s no rush or anything but, seriously, I’d love to lose this cock...”
Jen thought for a moment, then said, “I need you to pick both, alright? I promise I won’t make you do anything bad.”
“Sure, just get on with it...” Jess impatiently replied.
Jen let out a heavy sigh and said, “OK... Here goes... Transform or dare Jess.”
