Nothing about Natalie changes

Nothing about Natalie changed. "Darn," she said, laughing. "I guess it was worth a shot." She got up from the attempted boob job and slipped her own pants off, turning around and displaying her ass to Tom. "Although, wouldn't it be nice if this were bigger?" She started sliding it up and down underneath his hard dick. "What if... What if you're even more specific? How about wishing that Sarah's twin had a bigger ass than Sarah does?"

Tom gamely wished, and once again, Natalie remained exactly the same. She laughed ruefully. "I guess we can't get around it," she said, "You can't change me." She turned back around, and lined him up against her. "But at least you can still fuck me."

"Are you ready for your first time?" Tom whispered. She kissed him again, and slid down, slowly, without stopping. "Fuck daddy, you make me so wet," she whispered back. "Fuck your daughter. Fuck your wife. Ohhh god," and as she moaned, he kissed her again.

"You know," she said, thinking again as she started riding him. "Even if you can't change me... I wonder if you can change yourself." Tom cocked an eyebrow. "Wish for a bigger dick, daddy," she whispered lewdly. "Wish Sarah's husband had a bigger dick to fuck Natalie with."

Tom did.

Natalie's eyes popped way, way open and her mouth opened in a slight O. Tom was suddenly aware that Natalie felt much tighter. "Oh my fucking god daddy you're hitting my cervix" Natalie moaned as she bucked herself up and down. "Oh my god you actually gave yourself a bigger cock to fuck me with." Tom was amazed. It had actually worked. Why had none of his wishes worked on Natalie?

"Wait," Natalie said. "Wait daddy I know how I can become your perfect little sex doll." She kept bucking as she whispered in his ear. Tom cocked an eyebrow. "Daddy," she moaned, "Wish that Sarah's coin works for your wishes... And for mine. You'll only be altering the coin, not me. And if coin users can alter themselves, I can change myself too..."

Tom's eyes widened. It seemed like a dangerous idea, but Natalie felt so good riding him. It couldn't hurt, could it? He tried.

Natalie kissed him, and took the coin out of his hand. "I wish," she said, in between short kisses on his lips, "that Sarah's sister's lips were bigger, so she could kiss Sarah's husband better."

Nothing happened.

"Fuck," Natalie whispered, looking actually depressed. "Did it not work? Is it because I'm not a real person? Is it —"

They heard a creak outside the door. "Guys?" Sarah's voice filtered in.

"Fuck she can't see this," Natalie hissed, "She really thinks I'm just her twin sister. I wish Sarah was coming to tell us she's giving us alone time, and I wish that she thinks it would be hot if we fucked, because I'm her twin."
