"Well, it looks like the potion certainly works," said Kellie.
"It appears that way," said Kiko, "But we're not absolutely sure until Kana is pregnant."
"I think we've seen enough," said Mika, "I say it's time for us to take that potion."
"Us?" asked Kiko.
"Well, I'm sure you probably have some particular kitsune in mind who you'd like to have kits with," said Mika.
"I think the bigger question is why you would want to take the potion," said Kellie.
"Why wouldn't I want to be able to bear my own children?" asked Mika.
"Yes, but you realize that when you age back up, you'll go into heat immediately," said Kellie, "You won't just be able to have kits, you will be having them as soon as you can."
"I'm...kinda counting on it," said Mika.
"Why is that?" asked Kiko.
"I've been doing some thinking," said Mika, "About all these future kids coming back to the past."
"That's only happened in the other timeline," said Kellie, "Where we're all adults."
"It can happen here as well," said Mika, "And from what I heard, apparently these future kids can't go back further than the day they were conceived. And I'm thinking we need all the help we can get with this timeline-conquering warlord. Could you imagine how powerful me and Claudia's kids could be?"
Kellie was hesitant about this. She had a son of her own recently so far that's only caused Villar to become more active against them. Besides, she and Jack were still only teens. It was mainly due to Merlin's magic that she hasn't been hit by the social stigma that came with teen pregnancy. Would Mika and Claudia be as lucky?
But then Kiko said, "Are you really certain about this? This isn't just about getting reinforcements from the future. You will be responsible for raising the cubs you will have together. Are you ready for that responsibility?"
"If our alternate selves can raise a kitsune, so can we," said Mika. Of course, she didn't mention how their children would also be part-tiger, but that wasn't the point right now.
Kiko sighed and said, "I don't think I'll ever be comfortable with my little sister being with a tigress like this, but it was going to happen eventually. We may as well do it now."
"Is this really the best decision?" asked Kellie.
"It's her decision," said Kiko.
Kellie could see the pleading look in Mika's eyes and she caved in just a little bit. "Well, not just hers," said Kellie, "Claudia is the other half of this and I'm only onboard if she is as well."
==========
After they found Claudia, they explained what Mika's idea was to her. "So, let me get this straight," said Claudia, "In order for us to get some more help from the future, you want me to knock you up?"
"Well, almost," said Mika, "I think it would increase our chances of having cubs if I was a herm as well."
"What, really?" asked Claudia with surprise, "I wouldn't have thought you'd want to be a herm again."
"I've had more time to think about it," said Mika, "And actually, the idea excites me. Though I'm not sure if I want to have a penis outside of mating sessions."
"But you're ok with being a mother and a father?" asked Claudia.
"As long as it's with you," said Mika.
Claudia thought it over and said, "It's not likely for any of Villar's forces to attack here, right?"
"With my father here? They wouldn't dare," said Kiko.
"Then I guess there's no better place to do this," said Claudia, "Just let me get ready before I have that potion."
"But there's nothing wrong with your fertility," said Kellie.
"If Mika's going into heat, then I'm going into heat too," said Claudia.
"But you don't have to..." said Kellie before sighing and saying, "Fine, it's your choice."
==========
It took rather little time for Claudia to change into her hermaphrodite tigress form. Mika was able to make herself a herm with a minor adjustment. Kiko gave them a bedroom they could use and dressing gowns to wear. Kellie was only sticking around to do her part of the age changes.
"This stuff won't be too effective on me, right?" asked Claudia, looking at her glass.
"Well, since you're already fertile and not as magical a creature as Mika, you're getting a diluted dose," said Kellie, "Wouldn't want you to be unbirthed or become stuck in permanent heat."
"That was a joke, right?" asked Mika with a little worry.
"Don't worry. She'll be fine," said Kellie. Lilith's fertility formula might have been too strong for Claudia, so she was given a smaller dose. Personally, Kellie didn't think she'd need it. Just being aged up would be enough to put her into heat for this situation.
"Well, I guess this is it," said Mika before lifting her glass, "To parenthood."
"To parenthood," said Claudia before they both gulped down the potion. Perhaps because the two of them were still teenagers, the regression went pretty fast. In almost no time, their curves went flat as they shrank down, being engulfed in their dressing gowns. Kellie had seen a few kitsune kits already, but she hadn't see a tiger cub like this before. Claudia quickly went from mighty apex predator to cute kitten. The two of them were giggling as they batted at their growing gowns. Eventually, the two of them spilled out of them. The tiger cub waddled over to the fox kit, making playful growls. The kit yipped at the cub before trying to get at her tail.
"You two really are cute as buttons," said Kellie, taking a few pictures on her phone. These would definitely be worth a few laughs later. "Ok, enough time being cubs," said Kellie, "It's time for you to make your own cubs." With that, she made a wish with her ring. Once the two of them started growing, Kellie quickly left the room. She didn't want to be around when they got old enough to mate.
Mika and Claudia quickly surged through childhood, becoming more obviously anthro as they grew bigger. They gripped the bed as they stood up. They both thought the other one was pretty cute as they started into their tweens. But then both of them gave a small grunt as their testicles dropped and their breasts started to bud. As soon as they looked at each other's growing cones, their penises came out of their sheathes. "Whoa," said Mika, trying to cover her foxhood, "These things came out fast."
"Yeah, no wonder boys are such horndogs at this age," said Claudia before she started stroking her shaft. She probably would have been more embarrassed but she knew what was coming next and she felt so horny already.
Mika was blushing beneath her fur, but she was pretty turned on as well. It helped that Claudia was growing bigger in front of her. Her cone-shaped breasts were quickly rounding and out and swelling. Her hips and ass were also filling out as well, complimenting her trim waist. Claudia's body was also filling out with muscles as well as curves as she was growing taller. The tiger dick she was still stroking was becoming bigger in her hand. Mika felt her own dick getting harder and the pussy behind her balls was starting to drip.
Claudia grinned down at Mika as the kitsune was maturing. She may not be as tall or muscular as Claudia, but she was definitely more stacked as a kitsune than as a human. Come to think of it, Mika was looking a bit curvier than usual, also taller. Then again, Claudia felt a little bigger than before. The reason behind this became clear when Mika sprouted another tail. "Looks like we're becoming older than usual," said Claudia, who noticed her voice sounded deeper.
"I guess Kellie wanted to make sure we were at a proper childbearing age," said Mika. Not that she was complaining. Seeing Claudia as a mature tigress only made her more horny. And now Mika was feeling an intense heat that Claudia's mighty tiger rod could put out. "Speaking of childbearing, are you ready now?" asked Mika lustfully.
"I thought you'd never ask," said Claudia. She picked Mika easily before kissing her deeply. This kiss was a lot more passionate than their usual kisses, as can be seen by the way, they were rubbing against each other. Then Claudia dropped Mika on the bed and spread her legs out in the missionary position. "I'm going to give you so many kits," Claudia growled lustfully as she prodded against Mika's ass.
Mika let out a yip as she felt Claudia enter her pussy. "And I'm going to give so many cubs," she moaned as Claudia started thrusting. Her own dick was dripping a little at the thought of filling up Claudia. But at the moment, Claudia was dominant now. When Mika has her turn, she's going to make that tigress roar.
