"Hey big brother, since you used a wish on me, I can use a wish on you right?" Alice 1 asked.
"I don't see why not, that wish did effectively double your wishes, so I don't see the harm in using one on me."
"Okay, then I wish you were my twin sister, making us triplets." Alice 2 says.
"Wait, what?!" Jeff said but it's too late, he feels himself shrinking till he's the same hight as them as he feels my manhood slip away and form a womanhood, After which her clothes morphed into a belly dancer costume, leaving her an exact copy of her sister. "Something tells me... That if you had infinite wishes, everyone would be you."
The two Alices just hugged her, she considered using a wish to turn back but then saw that her parents had been watching this entire time, she realized She could either go back to being male and get grounded for who knows how long, or she can stay like this and her sisters happiness might keep her out of trouble.
