Misty was secretly a voyeur who used her bike as an excuse to travel with Ash. Brock was initially the same as in the anime, but little by little became influenced by Ash and he also became a nudist and exhibitionist. The two even agreed to share Misty (who remains dressed, wearing a sports bra and gym shorts that day).
It happened the day after Ash streaked to Oak's lab. Ash rode naked on his bicycle with Misty right behind him and Brock next to him. Brock didn't get nude yet. Wind blew on Ash's uncovered flesh as his bare feet pedaled the bike, and Misty got a good view of his buttocks squishing against the bike seat and even said to him, "Don't forget to disinfect the seat when you get home. Your ass must be making the seat smell a bit."
Ash chuckled, "Don't worry. If my own behind gets something dirty, it's not that hard to clean up."
Brock then asked him, "You're not cold?"
"Nope."
"How exactly did this lifestyle change happen?"
"I forgot to put clothes on while running to Professor Oak's laboratory. Misty was one of the first few ladies to end up seeing me in the buff. Shockingly, she liked what she saw and thought I had a hot bod, so I kept myself naked because it makes her and other women happy."
"Is that true, Misty?"
"Yep."
"Would you think that my body is as hot as his?"
"If you take your clothes off, I can give you a straight answer."
"Hmm..."
Stopping with the bike brake, Brock removed his orange vest and green shirt to show off his midsection. Misty's eyes widened in intrigue and surprise as Brock questioned her, "What do you think?"
"I think you are indeed as good-looking as Ash is."
"Aw, shucks."
Misty put Brock's vest and shirt in her backpack as they kept biking to a park about five miles from Ash's house. That park had a fairly level loop that was about 2.5 miles long, according to some park signs. Along the way, Brock got some admirers of his own as they usually things along the lines of, "Nice pecs."
Every time, Brock was complimented, he said, "Thanks."
Horny as he was, Ash really wanted some female eyes on him. After all, Misty convinced him that riding on a bicycle while butt-naked was sexy. Brock wanted more attention and believed that going all the way with nakedness could be effective if Ash got a lot of positive attention for his attractive physical properties, like a toned stomach and a penis with a decent length.
Upon reaching the park, Ash, Misty, and Brock did some stretching. It was a really nice afternoon, and Brock took off his shoes, socks, and pants. Misty giggled as he was down to his boxers, "You're really going further, Brock?"
"Sure am. Ash's nudity has slowly but surely gotten me all horny to the point where I just can't resist the need to take everything off."
The three of them did some stretches. When Ash reached down to touch his toes, Misty and Brock liked looking at his ass, the latter intended to show his own off real soon. They also stretched their legs, and the boys often had to wipe their feet since being barefoot meant getting their feet dirty from ground under them. After doing the downward dog, they were ready to bike on the path.
After about half a mile, the trio passed a couple walking their dog. Because they were going the same direction, none of them could see their faces, but Ash hoped the woman enjoyed the view of his uncovered ass. When that woman giggled, Misty assumed, "Guess she did."
Next, they passed some soccer fields. Some young adult boys were shirtless, and their sweaty bare torsos got Misty's juices going. Some of the players were jogging toward Misty, and she gave them a big smile before adjusting her sports bra to expose small portions of her C-cup breasts. When Ash and Brock looked at her chest, they could see a bit of cleavage. No one would have thought twice about the amount of skin everyone was showing, but hunched over their handlebars, they were giving a nice view of their intimate areas to those who cared to look. The cool breeze on their skin also helped cut the stifling humidity.
As they passed the park's rear entrance, they saw a young woman stretching. Brock and Ash hoped she was just starting his run because they liked her looks. She obviously was in shape, had a head of wavy brown hair than went down to her shoulders, and wore a midriff-baring crop top. They looked up at her approach, and locked eyes with her after giving her neckline an appreciative glance. Her smile was returned. After she breezed past them, Ash and Brock glanced back and were pleased to see her still checking them out.
By the time they passed the soccer field a second time, they were well warmed-up and had settled into a nice pace. All of them liked the feel of the soft wind on their exposed skin, and the feel of the narrow seat against Ash's sex organ kept him in a pleasant state of semi-arousal. Misty shyly returned his smile while staring at his member the way only horny females can.
Feeling horny and bolder, Brock finally decided to go all the way by pulling his underwear down and putting it in Misty's backpack. Now, anyone looking would know that Brock wasn't wearing anything at all, just like Ash. Misty's mouth was open wide as she saw Brock's cock, "You're actually doing it."
Brock said, "Yup. Ash must have gotten into my head."
Rounding a curve, Ash, Brock, and Misty saw another female runner in her late 20s, and she was moving at a good pace with long, powerful, strides. They smiled at her as their eyes met, she returned their grins, and made a point of moving her gaze to the boys and their upper bodies as she passed them. Amazed by the growing amount of appreciation, Brock grinned, "Wow. The women seem to like me. They like me as much as Ash."
Ash said, "Told you it was fun."
"Wait, I don't think you did."
"I didn't? Oh. Well, it is fun."
"You're right."
As Ash and Brock smiled prettily at a couple of women, those females gave the naked guys dirty looks as they power-walked. They were bold enough to hoot and whistle at the bare bikers, and even blew them both a kiss as they sped by. The thought of a nude male body fueling a woman's masturbatory fantasies made Brock and Ash even hornier. Misty's libido was certain at an all-time high by now.
At the entrance to a long straightaway, Misty stopped to look at Ash and Brock's chests. They were muscular, without being muscle-bound, and they each had a nice amount of hair that funneled into a line running pointing to their navels. Also, they had enough pubes to make her think that it had been a while since they last shaved their crotches. She then told them, "I bet you boys are tired of waiting for a hand on your dongs. With all that exposed skin, you must be sexually excited. I know I am."
Getting of his bicycle, Ash concurred, "I could use some release right now."
Brock said, "Ditto."
With that, Misty ran her left index finger up from Ash's navel to between his pecs before licking off the drops of sweat he collected around there. To Brock, she did the same thing with her right index finger. Both Brock and Ash shuddered a bit at her touches, and felt their penises erect fully. In terms of length, Brock's private was the same length as Ash's in both flaccid and hard states. Misty's pussy went from moist to soaking as she smiled at them with voice that was husky with excitement, "Looking good."
Tracing the outlines of Ash and Brock's nipples with her tongue, Misty happily groped their dicks, pumping them at the same time. Meanwhile, the boys leaned back against a nearby tree to keep themselves standing on their feet while moaning from having Misty's fingers around their cocks. They loved it. Plus, they savored the grass tickling their feet along with the rough feel of tree bark against their bare backs and butts. Ash gasped, "Jeez, Misty. You're nifty."
Given how much arousal was in their rapidly growing members, they knew it would take little effort for Misty to make them ejaculate as she pumped them more rapidly. To help her make their orgasms happen faster, Brock and Ash touched themselves by poking their belly buttons at first. Brock then told Misty, "Maybe you can tug our ball sacks while pumping us."
Misty giggled, "Good idea."
As Misty pinched the skin of their scrotums, she would pull them down until she could not pull them down any further, then released them to make them bounce up and down. She repeated that while Ash and Brock masturbated their own sex organs with one hand while grabbing their own asses with their free hands, squeezing their butt cheeks.
Within minutes, Brock and Ash were clamping their thighs and they slumped a bit as they came like banshees. Catching their breath, they nude boys slid down to sit on their rear ends. Misty collected their seeds in the palms of her hands. To her, their cocks were the same amount of gorgeous, not too big and not too small in length and circumference. The head and shaft were perfectly proportioned, and their felt sooooo good in her fingers. She smiled up at them as she licked the cum off of her palms, giving her opinion, "Yum."
Ash gave her a thumbs up, "We're glad we were able to give you what you need."
Brock agreed, "We're thankful that you enjoyed fondling us."
Misty said to Brock, "You're welcome. Want your clothes back?"
"Nah. Keep them. Honestly, I wanna be a nudist like Ash."
"Really?"
"Really."
"Ok. You and Ash should rest before we bike home."
