Josh and Anna had fucked extensively, and were now relaxing together in bed, cuddled next to each other.
Then the bell of the room rang. Josh then suddenly remembered how he'd given Carolyn the receptionist a command to come here once her shift was over. Was it she who was ringing the bell?
"I'll check the door," Josh told Anna.
He threw on his discarded clothes sans socks, so he would be no longer naked.
Josh opened the door, and there stood Carolyn. She was fidgeting, looking a bit nervous. She was dressed in casual wear instead of her uniform. Due to Josh's VIP powers he was 6 feet tall and sported big F cups which her lowcut top nicely displayed.
"Hello," Anna greeted. "I'm not sure why I came here. I just felt like I should... for some reason."
"Don't worry about reason," Josh replied. "Come inside, or give me a second first." He turned around towards Anna who was naked in the bed. "A guest is coming. Is that alright?"
"But I'm naked," Anna protested.
"You can cover yourself with the bedsheets, she won't mind. But is it okay for you for her to come in."
"It's o-okay," Anna meekly replied.
Josh invited Carolyn in. She seemed a bit confused, so Josh figured he could start talking.
"You see. My fiancée here, Anna, she has a fantasy where she wants me to fuck other women."
Anna blushed at her fantasy being revealed.
Josh looked at Carolyn, straight into her eyes. "So we both wonder if you want to help us out."
"I see," Carolyn replied. "I, um, do find you attractive, not just you, but Anna as well. I think that's why I came here, because I was attracted to you, so I'd be okay with it I think." Carolyn looked towards Anna. "But is it really fine with you? Do you really want this? For me to, um, have sex with your boyfriend, um, fiance I mean."
"Yes." Anna blushed. "I've fantasized about it for so long. I know it's weird, but I do want it."
"No, I'm not judging you or anything," Carolyn clarified. "I just want to make sure we are all on the same wavelength."
The trio chatted a bit more until Carolyn asked, "So, have you guys tested the room yet?"
"I can show her," Anna looked towards Josh.
"Go ahead." Josh nodded
Anna pulled the bedsheets away, revealing her large boobs.
"Wow," Carolyn gasped. "Those are huge. Thinking back when I saw you at the reception, you did not have those boobs."
"Nope." Anna giggled and covered her mouth.
Josh knew that Anna's chest wasn't the only change, but with his VIP powers making Anna's Asian ethnicity retroactively a thing, Carolyn's memories of Anna were different as well.
Anna stood up and walked up to Carolyn. "You're so tall."
"I know." Carolyn laughed.
The two girls made quite a contrast, almost a foot of height between the short busty Chinese girl and the tall and also busty blonde.
Josh had an idea. "How about you swapping heights," he suggested.
"Yeah! We could do that!" Anna seemed eager as she looked up towards Carolyn.
"Alright then," Carolyn went along. "I figure you know how the room works?"
Anna nodded.
Then the changes started. Their eyelevels became closer as Anna became taller and Carolyn shorter. It wasn't just a simple stretch and squash of the entire body. Most of Anna's gained height came from her legs elongating, while her torso didn't stretch much. Similarly, Carolyn's body got a different wider profile as she became shorter, though Josh was the only one who could remember that Carolyn was actually returning to a height close to one she had before if only about an inch shorter.
With the height swap over, Anna towered over Carolyn and grinned.
Carolyn didn't seem unhappy either as she was eye level with Anna's boobs. Noticing this, Anna pulled on Carolyn, pushing her face right into chest. "Come to mommy," Anna cooed, as she smothered Carolyn.
Carolyn didn't resist, and suckled the boob that had been placed in her face.
Meanwhile, Josh enjoyed the show happening before him.
"Will you be a good girl?" Anna started. "Will you be a sweet good little girl who'll get fucked by Josh.
Carolyn nodded as much as she could in her position.
"First, I want you to do something for me. This might sound selfish, but I want your boobs to be smaller. I've always been the tiny flat girl, and now that I'm tall and busty. I don't want you competing with me." She grabbed the shorter girls boobs. "I want you to be petite, more than I were."
Carolyn's chest shrank as she went along Anna's fantasy.
"And remove some years," Anna added. "Become a fresh 18 year old."
The once 32 year old Carolyn did seem to become younger, and Josh noticed that Anna was also changing in the opposite direction, becoming older, and curvier as well. Before, Anna had been kind of a stick with two massive boobs at her chest, but now, Anna's body was catching up, her rear growing, her previously thin legs now sporting thick thighs.
"Mhmm." Anna nodded. She released her hold of Carolyn, and studied the petite blonde. "You're so cute. You look just like what I had in mind."
"Heh, I tried," Carolyn answered.
Anna looked between Carolyn and Josh. "I want you to fuck. Just you two. I'll watch and enjoy the show."
Carolyn and Josh looked at eachother. Then, Josh looked at Anna. He was caught offguard by Anna turning herself into a milfy Asian woman, and he found her new self super hot, but he was supposed to fuck Carolyn, and it wasn't like she was unappealing either. Anna had brought out a very cute girl out of Carolyn, whom had an appeal that worked well on Josh.
"Can you take the lead?" Carolyn asked.
"I will." Josh smiled.
