You could hear the Pichu responding somewhere far above you, but you were far to focused on trying to escape the smelly expanse threatening to envelop you.
You manage to clear your legs out of the grasping fur pretty easily, but your arms are stuck too deep to simply pull free. You push one hand against the dirty foot while pulling the other one towards you.
After a slight struggle you manage to free your one arm, but discover that you also helped your other get entangled more severely. Trying to peels back the slick strands with your now free arm quickly proved futile. By the time you had freed your hand, more waves of the Pichu's footfur had washed over the free parts of that arm, claiming it up to your elbow.
You needed some leverage to free yourself fully from the Pichu's smelly extremity. Finding nothing of use beneath the tiny mouse pokemon's paw, you shift yourself on your side. Bracing your shoulder against the vast yellow ceiling above, you start pulling with all your might.
~~~~~~~~~~~~~~
Far above you, the Pichu was unsure what had happened. He'd expected your panicked struggling to continue on for a while. Then he feels you push your entire body against the sole of his foot. He certainly wasn't expecting THAT, but soon a knowing grin started spreading across his face.
"Chuuu, I didn't think you'd give me a footrub of your own. Could it be that my tiny toy likes being near his owner's footsies?"
He gently starts grinding his smelly paw against you and immediately feels you press your body deeper into his fuzzy sole. This only served to confirm his suspicion.
He could hardly contain the glee in his voice.
"You know this is supposed to a be a punishment, right?", he mockingly asked you. "Chuuu, don't worry little plaything, I'll still forgive you if you do a good job with my paws".
The Pichu then shifted around slightly to lean against a nearby stump. Propping up of his feet as he relaxed to fully enjoy your ministrations.
~~~~~~~~~~~~~~
Underneath the yellow foot, you are in agony. You had only just managed to make some progress in getting your arm out of the Pichu's footfuzz before a crushing weight from above started grinding you into the dirt below. The pressure forced most of the air out of your lungs, leaving you to breathe deeply from the the mouse's footscent, and the slick fur above got busy wiping days of accumulated sweat and grime onto you, effectively turning you into the worlds smallest doormat.
You realize the sadistic pokemon must've felt you were trying to escape. This discovery gave you newfound strength, blocking out the pain, disgust and muffled voice of your tormentor, you wrest your trapped arm away from the crushing wall of fur with all your might, and you finally feel it slide free from its disgusting prison.
Your happiness was shortlived when you realize the half of your body you used to push off against the mighty sole had now been reclaimed by the fuzzy foot. You are devastated, but your despair quickly makes way for panic when you feel the entire foot shift upwards, carrying you with it like a stubborn piece of gum.
Reflexively, you brace your freshly freed hand against the yellow wall in a futile attempt to cushion the impact, only to curse your stupidity as you find the curtain of fur easily parting to accept your last free appendage in its warm embrace once again.
You start blindly struggling in a desperate bid to get free only to find that the yellow wall you're plastered against works much like quicksand, drawing you deeper inside the more you try to free yourself.
Slowly your struggles carry past the coarser, dirty outer layers of the Pichu's footfur and into the gentle embrace of the softer fluffy inner fur. Though cleaner, the atmosphere here is so hot and humid you'd think you ended up in a tropical forest, if forests could smell like a baby pokemon's feet. you feel the outer layer of fur close over your back and come to a stop close to the pokemon's skin, being able to feel it move behind the pillowy wall of your smelly prison.
The fur is still strung tightly around your body leaving your only possible action to wiggle in place uselessly, being able to breath nothing but the Pichu's potent footmusk. With the heat and humidity of the pokemon's paw constantly sapping away your strength, soon even that is beyond your capabilities.
It's not long after you've given up on moving that you feel the entire foot twitch and shift, seemingly trying to surround you in its embrace, and you hear your captor speak once again, almost pleadingly:
"Chuuuuu, keep going. You were doing great"
It dawns on you that the giant rodent had been experiencing your desperate fight for freedom as nothing more than a relaxing footrub
