Yes, with a twist

The picture shifted, and as Tom was about to breathe a sigh of relief...

Natalie's suddenly-huge boobs hit him in the face. She moaned as her nipples brushed his lips, and he suddenly felt how much tighter she was.

"Ohmyfuckinggod," she said, still crying, but looking happy. "Oh you feel so, so good Daddy. Oh my god I'm real. The wishes work on me. I didn't undo them, I just made Sarah back to normal, so now I'm..." She slipped up and down on him, and Tom realized how much... better she'd become. Everything felt so incredible. Her wishes had suddenly all come true, in the way she'd intended them to, now that the coin wasn't satisfying them by changing Sarah.

"I'm your fucking sexy little sex doll daddy," she whispered in his ear. "It worked on me. You made me this way. I made me this way. Fuck me so good daddy." She kissed him deeply and they resumed lovemaking.

A while passed, and Natalie's phone dinged. She looked over and saw a message from Sarah, and grabbed her phone. "Oh my god," Natalie whispered. "Look at what your wife is doing..." She turned her phone to Tom.

He saw a picture, clearly taken by someone holding Sarah's phone as she sucked on their large dick. Presumably this was her teacher. "Oops," Natalie said, "I guess I didn't undo that..." Tom reached for the coin, and Natalie held it above her head, laughing. "Uh uh," she said, "Not while you're fucking her sister. Let her have some fun if you're going to." Tom kept reaching for the coin as Natalie tried to keep it away. "I wish Sarah's husband would let her have some fun, because he's having the best sex of his life with her sister," Natalie burst out quickly, grinned, and bit her lip.

Tom's fingers still stretched out. Natalie gyrated on him, still smiling and biting her lip.

Tom put his hand down.

Natalie's phone dinged again. She showed him the message. "Inspiration for you and dad today ;)" it said. Tom briefly noted that her teacher's dick was... Actually bigger than Tom's own used to be, although not bigger than Tom's was now, given the earlier wishes. Natalie quickly fired a text back. "OMG, no! You know I can't do that! That's so gross!" Natalie winked at Tom. "Can't have her getting too suspicious right after you made that wish to make her not find me threatening," she said.

"Alright, but no more wishes that change me, okay?" Tom said. Natalie kept smiling.

"I promise to only make fun wishes that change you," she said, still smiling and gyrating. Tom shook his head, but before he could finish, Natalie rattled off another wish. "I wish Sarah's husband would let me make fun wishes to change him," she said, still smiling.

Tom laughed, but was cut short when Natalie's phone dinged again. She seemed to laugh silently, but this time, didn't turn to show it to Tom. "What is it?" he asked.

"I'm not sure I should show you..." she said.

"Come on, after that wish, you owe me."

"Okay..." she said, and turned the phone around. This time, it showed Sarah on top of her photographer — her teacher — his dick halfway into her pussy. Her eyes were rolled slightly back, and Tom realized he wasn't sure she'd ever made that face with him. Underneath it, a message read: "Okay, want to fuck Mr. Peterson with me then? His dick is huge <3"

"Don't worry daddy," Natalie whispered to him. "I would never fuck anyone else besides you. And your dick is bigger now anyway." She fired off a response: "OMG, no! First of all he's our teacher. Second of all I can't fuck my sister's man!" But she kept doing precisely that as she slid up and down on Tom.

Her phone dinged once more. Tom saw the picture: the man had this hand wrapped around Sarah's throat, clearly pushing her the rest of the way down, the large cock now fully embedded inside her. Sarah's tongue lay out of her mouth and her eyes were fully rolled back. Beneath it, the message read: "Kk prude gotta go cum on this perfect dick like a thousand times <3"

Natalie tossed her phone towards her pile of discarded clothes on the floor. She wrapped her arms around him and fucked him lovingly. "Don't worry," she said, "She can have her fun while you fuck me." She pushed her boobs out towards him and he sucked on her nipple; she gasped, and ran her arm down his side and his arm, palming him the coin and wrapping her fingers through his. "Alright, you've got the power now, is there any problem with any of my wishes?"

Tom grit his teeth in faux anger as she continued riding him. "Fine, baby. But..." Natalie looked at him quizzically. Tom knew he couldn't stop her from making "fun" wishes anymore — whatever that meant, her wish still stopped him — but he still wanted to put boundaries. "I wish my hot, big-boobed daughter Natalie can _only_ make fun wishes to change me." Natalie grinned.

"Oh, you want to keep me under control? You want to collar my ability to make wishes?" she said, flirtatiously. "Give me that coin and let's see what I can still do," and she extended her hand with her palm out. Tom passed her the coin.

"Fine, daddy. If you want me collared so bad..."

Tom waited.

"I wish I was wearing a collar and leash right now, and that my Sarah's husband fucking loved it, and he also loved it when I reminded him he was actually my sister Sarah's husband, and that he's my daddy." A collar appeared around her neck, and Tom found himself holding the leash. "Do you like that wish... daddy?"

Tom stared at her for a moment, then flipped her back onto the couch. "Oh yes daddy," she moaned, "pound your little girl."

"Which of my little girls do you mean?" Tom asked, teasing, refusing to fully enter her.

Natalie laughed. "Oh fuck, pound your wife's sister, the one with bigger boobs, fuck her tighter pussy daddy." Tom growled and slammed into her. "Yes daddy, own my little pussy daddy, this collar is because I'm yours, you own your wife's sister and she can't stop fucking you daddy I love it please don't stop I absolutely LOVE making fun little wishes for you daddy that make you pound me so hard with the dick that made me, you literally made me daddy, with your wish but also by knocking up Abigail with this giant dick, I was a little sperm I came out of this dick and now I grew up and I love it so much, oh my god I'm thinking of another little wish for you daddy I think you're gonna love it..."
