perverted potion prankster Naruto

That was... something?"

Asia looked as a giant creature descended back into the waters.

"Yep, that was Jail the Squale, 1/3rd Whale, 1/3rd Giant Squid, and 1/3rd Tentacle Plant. He's good for deep sea transportation, the tentacles in his mouth can transform into furniture, and he doesn't require food due to him conducting photosynthesis. He is a mobile underwater base, now you don't cause any trouble Jail, you here me!" Naruto called out to the massive creature going back in the water. He could summon his monster to him whenever he wanted to, but he would allow him to roam the oceans free until the next time that he was needed.

Jail was a good boy who never hurt anyone.

Well, Jail DID do that one thing with the tourists when he was young, but nobody would ever believe the story those tourists told, so it was like it never happened.

"You have no idea how long it took me to make his breath smell like vanilla, that was actually the hardest part about creating him. The days I used vanilla instead of peppermint, ah, those were the challenges." Naruto had different concerns than Asia, who was just a little surprised at how comfortable the experience was.

Inside of Jail was a small house when he transformed his tentacles into furniture, so the entire 18 hour journey to Japan felt just like they were on a small vacation rather than travelling by strange creature. Asia noticed that Dan was coming out of the water, and behind Dan was a female version of Dan, who had been following Jail to offer protection from deep sea monsters.

"Thanks, I'll summon you two when I need you, until then feel free to do what you want." Naruto told his Manphins, who jumped back into the water. "Okay! Now, onward to Kyoto, we've got some fluffy fur to collect, and then off to Kuoh!" Naruto started to walk in the direction that they were going to go.

"Uh... are we going to walk the entire way?" Asia asked with some confusion.

He looked at her.

"Of course not-"

-2 Hours Later-

"-this is how we travel." Naruto stated as he showed Asia the hypnotized woman who was driving them in her car. There was a Mini-Shelly on the front of the car, controlling her actions, and both Naruto and Asia were sitting in the back seat of the car. It was still going to be a couple of hours until they got to Kyoto.

That gave him time to do some experiments in the car, while Mini-Shelly did his duty and kept the woman driving according to the law.

"Is she going to be ok-" Asia accidentally glanced at Mini-Shelly, before she shook off the hypno power from her own repeated exposure to it. "-when this is done?" Asia asked Naruto, and he nodded his head.

In his hands were two potions.

A red and a blue.

"Yeah, she'll be fine... she will be confused about why she is in Kyoto, but we can leave her gas money in the front seat." Naruto opened the red potion after it became the color red he wanted, and he started to add some... chocolate to it? Asia watched as Naruto added dark chocolate to the potion, before the chocolate was dissolved into the potion. "Chocolate has a natural property to make people happier, it activates chemicals in the brain, but it also activates chemicals that can increase breath growth." Naruto stated as he opened up the blue bottle and added coffee to it.

"Coffee?"

"Coffee can actually shrink breast size when combined with working out, since caffiene is a fat burner... Now drink this Asia, and show me your boobs." Naruto stated as he gave Asia the blue potion to drink. She seemed a little surprised, and she blushed bright red as she took off her top and took her bra off right after. "Nice." Naruto responded when he saw her bare breasts.

Asia went a deeper red.

"Like this."

Naruto grabbed her boob and he gave it a squeeze.

"EEP!?"

"Sorry, couldn't resist... soft and supple, and a little firm. Now drink." Naruto handed the potion over to Asia, to which she raised it to her lips and drank some. Before she could drink it all, Naruto stopped her by taking it away. He corked it up when there was half remaining, before he turned his gaze back to Asia's boobs.

Asia gave a small moan as the size of her chest began to visibly shrink, until her decently endowed chest shrank to a mere A-cup, her boobs becoming barely there. Naruto looked at them with a critical eye.

"You can undo this, right?" Asia asked Naruto when she looked down at her chest, and saw that she was now basically flat chested.

Naruto reached out and he grabbed her chest.

"Just as soft, but the suppleness is reduce by a lot, and it's more firm than before. These are really nice too, and here I thought I had a preference for bigger ones. I do lean towards ass, but now that I'm-" Naruto didn't stop talking as he fondled and held onto Asia's boobs. He even brought out a ruler and he measured her nipple to see if there were any changes to it. The color had changed from a pink to a very pale pink, but the size remained mostly the same. "-thinking that I like all boobs as well, well, attractive ones... but yours have got to be my favorite." Naruto stated as he got a closer look at Asia's chest.

Her heart was pounding.

She was embarassed, but happy to be able to offer him her body for his experiments, and her shy smile didn't leave her face. Naruto put his ear to her chest, and he listened to her heart beat.

"Mine are your favorite?"

Asia didn't know what he meant by that.

"So tell me, are they more of less sensitive than before right now?" Naruto asked Asia as he teased her nipple, and she closed her eyes to focus on the feeling. She squirmed in her seat though, since he was very talented with his hands. That should be expected simply because of how much he works with his hands on potions, his fingers didn't apply more pressure than what was needed.

"... About the... mmmm... same?" Asia couldn't feel a real difference.

Naruto's hands came off her breasts in less than a second, and he started to write down her response as well as his own obersvations in his notebook.

"Perfect, but a little disappointing, the potion isn't suppose to make you more sensitive, but I still wanted to make you cum to see your cute orgasm face again." Naruto didn't hide his own disappointment in the lack of failure. He would have been okay with failing in that aspect of the potion, but it would seem that it just wasn't meant to be this time.

Well, he did still have that Sensitivity Potion, but he had yet to dilute it so if he applied it to Asia's boobs the effect might be too strong. She came twice from him touching her hand, there was no telling what it would do to her if he put it on her boobs.

Naruto snapped his fingers.

Asia's chest started to grow back to normal.

"... How did that work?" Asia asked, since he didn't make her drink anything to undo the effects of the potion.

"I made these two potions to activate and deactivate at my command, my magic can be used to activate the effects at any time I want... at least until the potion leaves your system. Now drink this one." Naruto passed her the red potion. She drank half of it and handed it back to Naruto for him to cork up.

Her chest grew, and it grew until her boobs were twice the size of what they were before. She went from moderately endowed, to very well endowed.

"Wow." Asia stated as she looked down.

She kind of liked this one.

"Nice."

Apparently, Naruto liked it too, because Asia was used to him saying that whenever he saw something he liked on her body. She looked at him, and she saw him focused on her boobs completely just like before. He turned his focus away from her boobs, wrote something down in her notebook, before he turned his attention back to her and grabbed them.

"Oooooh, way more soft and supple, but a lot less firmness. My fingers sink into them a lot more easy, and they seem to sag a little bit more than before thanks to gravity. Perky for their size, but a little skin on skin." Naruto felt the underside of her boobs, where her skin was touching skin. They moved and jiggled in his hand a lot more visibly than when they were small.

He started to measure them.

Her nipples became a slightly more rosy pink than before, and they increased in size slightly as well. They were a little colder to the touch than before, and he couldn't feel her heartbeat as well either.

"Heheheheh... that tickles." Asia giggled when Naruto's fingers worked the skin around the sides of her breasts, closer to her armpits.

"I'm actually going to put that as a plus in the flat chest size, you can feel their heartbeats better, but this pillowy softness and coolness is nice too... nice." Naruto stated when they hit a bump on the road, and her breasts gave a massive bounce in his hands. "Heh... hehehheh... Oh... I have got an evil idea for this potion." Naruto stated as he snapped his fingers and her chest shrank back to it's normal size.

He was going to change up the formula for this potion a little, so that he could use it as a prank against people. He would write down the original formula, but there was no way that he was going to sell the original potion to people. He was going to save that one for his experiments.

"... Oh..." Asia looked down at her own chest again, and she felt a little sad that her larger size was back down to her normal size. Still endowed pretty nicely, but not nearly as large as before. Asia started to reach for her bra, before she noticed that Naruto was holding it. Naruto was applying a dust to it that coated the inside of it. "What are you doing to my bra?" Asia asked him.

"You won't need this bra, I'm going to use it for my experiment. You can go braless for awhile, I want to see if I can bring your bra to life." Naruto stated to her as he started to experiment with her bra. He wanted to make a bra that could always adjust to the user and make them feel as comfortable as possible, a sentient bra.

Asia watched as super tiny tentacles started to grow on the inside of her bra, small enough that unless you paid close attention, you wouldn't even notice them. Asia watched as her bra started to move on it's own as Naruto experimented on it.

"Why?"

"Why not, it sounds pretty fun to see if I can do it. Anyway, don't put your shirt on yet." Naruto told Asia as he gestured for her to stop.

She paused.

"Why, are you going to do another experiment?" Asia was a little curious, but she stopped putting her shirt on.

He grinned when they hit another bump in the road, and her boobs bounced.

"Nice."

That was why.
