"Pwah! Pwah!" Cotton dryly spits and wipes her mouth with the back of her hand, sitting upright as you roll off of her. "Why are you balls so big?" A welcome complaint, you supposed, as she desperately tries to recompose herself, getting to her feet and dusting herself off.
"Well, I'm glad this paid off then. I don't know if I'd ever live it down if I took a mouth full of Human junk for nothing. Alright, lead the way then! Let's go save our Pokémon!"
Refocusing on the task at hand seems to restore some of Cotton's mood and determination, although you've taken care of enough Lopunnies and Bunearies before to recognise more to her complexion and body language. Embarrassment in abundance, but also a little something more. If she weren't as anthropomorphic you would assume it to be the beginning signs of... going into heat? Could such a thing still apply to even a more humanised Lopunny like Cotton, with all of her comments about your own sexual eagerness? That could explain why she's been acting odd since going into this tunnel together, keeping her distance from you a little more after first getting a look at your naked body. Why she's been struggling to look away from you on the occasions you've teased her. Could it be that all this time you've been triggering some kind of heat response within the poor Lopunny and she's been trying to keep it under control?
Flaw Learned:Spoiler (click to show/hide):
Need to Breed - Lopunnies have a reputation for a reason, being prone to going into heat regularly. Though Cotton strives against these urges in preference for pursuing her dreams of being a Rescue-Mon, she still feels these urges all the same. She has a harder time resisting effects that would arouse her, and stays aroused for longer, growing needier and needier until she finds a male that can satisfy these urges.
Regardless, she has her head in the game at the moment, and the two of you have a Plusle to save. Knowing the way to go, it doesn't take you long to find the tunnel passage that should lead you right towards where you saw Volta's ears. And as the two of you run in that direction, you start to feel trembles run through the ground below you. Even the walls of the tunnel seems to shake, loose rock and dirt falling to the ground. You start to hear it now, a large rumbling... whatever is causing it is very big and moving fast... possibly even heading right your way given how intense its starting to sound. Was it digging a new tunnel through the dirt, or just moving at a fast and forceful pace through one of the tunnels its already made.
Though out of the darkness in front of you comes not some lumbering beast, but a slender and topless Plusle who rounds a corner just to slam straight into your face.
"GAH!" You would appreciate it as quite the cute cry of alarm if your head wasn't currently spinning as you topple over and find your butt on the ground yet again - this time with no curvacious Lopunny to soften your fall.
You do however have a different cutie falling over your front. Her small, perky breasts press against your bare chest. Her flushed cheeks, marked with her red symbols that give them an added rosiness, are scuffed with dirt from her time in these tunnels. Her big, bright eyes blink away the dizziness from the impact before look at you with wide astonishment, gasping as she realises she's run into another person down here. "Oh, sorry-" the apology starts coming before she finished opening her eyes, and stops once her mind catches up to the situation and she gives you a bright, slightly lopsided smile. Her hands push down on you gently to prop herself up, one finding itself planted against your strong chest, the other moving against your thigh as she shifts to try and get a better look at her saviour. Your cock is treated to yet another helping of accidental attention as her fingers and wrist graze against it - although it didn't help that it was already pressed against her abdomen. She gasps as she seems to realise what it is she can feel, and glances down, her eyes widening even more as she sees your exposed dick and just how large you are, a flush coming to her cheeks.
She swallows and pulls her eyes away from your dick and back to yours, pushing herself up a little more. "High, I'm Volta! Nice to meet you. Come here often?" She asks as she lifts herself up now to practically straddle you, her hips pushing down against your cock gently as her thighs slip around your hips. She holds out her hand as if to shake it, seemingly forgetting within in seconds the awkwardness of this encounter. Then a few moments later she pulls her hand back to plant it against her face. "Oh, stupid, stupid Volta. Of course you don't come here often. Sorry, my mouth tends to run away with itself when I meet new people."
"Volta, are you okay? Ohm came to get us. He said there was something down here with you?" Cotton says, moving over to help Volta off of you properly.
The Plusle bounces up with a surprising spring in her step. "Ohm! Is he okay? I'm not hurt, but I've been playing a pretty darn scary came of hide and seek down here. There's something big and it keeps trying to catch me... Oh, right, yeah, it was chasing me, wasn't it. Sorry, I go a bit distracted by your naked friend over there. Hey, hang on a minute, why are you naked?"
She gives you a quizzical look, but Cotton ushers her along past you. "We should get moving fast. Come on Bryce." She reaches down with one hand to help you up. "Whether we want to deal with this thing or not, we should get Volta out of here first if we can."
(Now that you've seen them both)
