Shamrock Cavern

Half an hour passed as Ash half heartedly told his story leaving out various crucial details and looking at the ground as he slowly chewed the stored food that Brock had cooked earlier that day. It was cold and quite frankly not as big a serving as what Ash would normally eat but that wasn't what was bothering Misty. Pikachu and Chikorita - inexplicably human were working side by side as a solid team for once in an attempt to clear away more of the scrub as per Brocks suggestion, but that wasn't bothering her either. Brock was currently going through all three bags (including Misty's) and sorting through shirts, shorts and underwear in an attempt to find something that would fit the new group members and while that did bother her a little it wasn't the main concern. As Ash sat there telling his story and how he had found Chikorita in human form the fact that he avoided looking at Misty WAS bothering her a great deal. Especially when he muttered about the three of them having passed out.
But most importantly was Ash's current state of undress. She'd catch herself looking at the small patch of underwear currently covering his boy-hood or the small serving of muscle on his chest and arms. He might not have been much to look at, certainly not in comparison to the pokemon boy currently labouring away behind him, but he was all hers.

"So, basically you have no idea what happened!" Brock confirmed. Ash seamed to think about this for a moment before replying, "Yep, Not a clue! ... But the cave kinda closed up as we left!" He added the last sentence hurriedly and hoped nobody noticed.
"Pretty much same as ever." Misty's feminism chided before the rest of her could stop it. She shrugged it off and stood up. "Seams to me we should check out this cave anyway while we're here."
"Good Idea!" Brock replied as he continued looking through the backpacks which were slowly being dismantled around him.
"What, No, I told you the opening kinda closed up, like a big door, no more like a rock-slide!" Ash gestured back and forth with his arms as he spoke and Misty gave his a sceptical look.
"Ah-Huh!" Brock arose from the depths of one of the bags like a victorious Gyraidos and varnished to pairs of pants. "This is a pair of Misty's and they go to you!" He tossed the pants to Chikorita who caught them automatically using the vines from the back of her neck. Stopping what she had been doing and raising the shirt Ash had given her she looked at her exposed lower half expectantly, holding the pants in front of her with her vines and looked back at the group quizzically just as Brock tossed the second pair to Ash.
"What the?"
"Let me help you with that Chiki !" Ash and Misty spoke at the same time, Misty promptly heading over to Chikorita as Ash approached the bags.
"You were supposed to be looking for stuff for Pikachu!" he commented as he handed them back, "Not me!"
"Those are the ones that lost all the elastic when I washed them!" Ash examined the pants again and saw the that while they were his they indeed had been stretched slightly. "They’re the closest match we have and quite honestly the pants Pikachu's wearing now are extremely tight on him." The pair looked at Pikachu, still hard at work - This time trying to cut through an extremely thick piece of bracken with a tiny bolt of lightning. Ash swallowed a lump in his throat on realising that he'd been staring at Pikachu's firm build and looked back to the pants he was holding.. Across the way Misty was attempting to show Chikorita how to button up pants and while the short they were working with were baggy around the waist and short in the leg they seamed to be making headway.
"I've cut a hole in the backside," he continued. "If you look at Pikachu you'll see his tail is pressed against back at the moment, the hole will let it sit out behind him comfortably.
Ash looked back at Chikorita and grimaced. "Oh that looks horrible!" He called out-loud before his brain could intercept the message. Seconds later he found himself cowering before the might of two very angry girls.
"That's not what I meant!" He screamed as they bore down on him. Behind him Brock crossed himself and decided to stay well out.
"I Meant Chikorita Looked Beautiful As She Was, And Those Pants Work Best On You Misty!" The words blurted out like lightning as Ash Cringed Misty's heart melted again. Grabbing Chikorita by the back of the Ill-fitting pants she stopped the girl short making her look quizzically at Misty. "That was an apology!" Misty explained. "It's okay to terrorize Ash [ i ] only[ / i ] until he apologizes."
" Chik ?"
Misty racked her brains for a suitable response to Chikorita's question. "Then we save it for later and throw it back in his when he least expects it!" She finished with a sigh of relief. Silently she swatted her sense of femininity to one side as her brain tried to process Ash's earlier statement.
She realised suddenly.

"No, Pikachu! Not out here...!" Waking up to herself Misty suddenly noticed Ash had given Pikachu the new pair of pants. Completely unabashed Pikachu had whipped off his existing pants and handed them to Ash without bothering to hide his older male form. Ash was currently struggling with Pikachu in an attempt to cover him up and watching the pair Misty found herself stifling a giggle, then noticing Pikachu's larger boyhood blushed and turned away. Behind her Chikorita had removed the pants upon Ash's suggestion. It was true; her fur did hide most of what needed to be hidden. Misty sighed outwardly this time unaware of the antics around her or Brocks stoic expression.

She thought
