Bete noire and frisk domination

You are lying on the floor, the pink demons shadow looms over you.
"you couldn't beat me, even if you tried" said betty
You are too out of breath to muster any words so all you do is lie there pathetically, Betty crouches down.
"hmmm.. I noticed during the fight that your eyes were looking at my feet, is that true"
You gather enough breath to say "no-"
Betty knew you were lying, so she removed her boots and socks, stuffed her sweaty socks In your mouth, then kicked you in the face 100 times, you blushed. Your face had a foot shaped dent in it, an inch deep.
"Don't try lying to me again, you little foot perv, I think you know what's about to happen"
Betty stood over you, with her legs on each end of your chest, she sat on your stomach, she raised her feet and rested them on your face.
"hahaha ha, you look so pathetic like this how about you get a good whiff" she moved her feet so your nose was in between her toes, you take a deep sniff, she giggles "I knew you liked my stinky feet!"
About 5 minutes of you smelling her feet, she said "alright, this is getting boring, so now I want you to lick my sweaty soles" you refused "you better lick my feet or else your face will have a foot shaped dent in it" out of fear, you started licking her feet, she guided you by moving her foot around your now worn out tongue, after another 5 minutes, she commanded akumu to pin you down while she went somewhere, she came back several minutes later with frisk "... I know frisk, you hate me but hear me out, see them?"
"yeah..?"
"they're the one who treats your feet"
"and why should I trust you? And why is there a footprint in his face" frisk asked
"because I want us to have some fun, you know? And the footprint was me stomping the heck out of him, see?" she inserted her foot into the dent, her foot fitted perfectly onto your face
Frisk finally came along and took off his shoes and socks to sit next to Betty for 5 minutes of foot fun, Betty and frisk took turns smothering you with their feet, until frisk took the lead and stood on your face completely with his sweaty yellow feet, you enjoyed this every second, eventually frisk left you and Betty alone, Betty had finally gotten tired of you
"I think it's time to wrap up our little game here" she stands up and picks you up and stands you in front of her
"now, since you adore my feet so much, I am going to give you the privilege of getting knocked unconscious by them"
Betty then rushes at you, you try to hit her away but she dodged, then did a handstand and did a barrage kick of 20 to your face, knocking you out, giving you a concussion and a bruised eye, the last thing you heard was giggling and you saw, Betty's feet had a lot of blood on them.
You wake up feeling lighter than normal, lying down, and you feel something in front of you, it appears warm and moist with the occasional pressure on your body, you tried to climb up the wall, you failed, you hear someone sit down from outside this unknown environment, you hear shuffling and the wall in front of you lift away revealing that you were underfoot In Betty's boot, Betty and someone else who you can't see were talking, Betty noticed you as she revealed the bottom of her foot that you were awake
"oh, hello little guy, how was the walk?"
The other person looked at her foot and laughed, it was frisk
"that's right boy, me and frisk are now friends, and I killed off that evil akumu"
"yeah, your welcome, Betty, but you said you owed me a favour after that, do you think we could share this human between our feet?"
"of course frisk, but when were sick of him, we do as I say, OK?"
"Ok" frisk agreed
Frisk took the first turn, placing you between his toes, "how's the smell, tiny boy?" frisk said at his golden foot and you
1 year later
"hey Little guy, do you want to become normal size again?"
You nod desperately
"okay" Betty gets her phone and calls frisk
"hey frisk, it's time"
5 minutes later frisk arrives and Betty gets out a dusty Ray gun and Shoots you with it, you immediately grow back to a good 5, 11
"you ready frisk?"
"ready as I'll ever be"
Betty and frisk grab you and take you to the middle of nowhere, take off frisk s footwear, and pin your head on the ground with frisks feet on top of your face
"ready?"
"uhh, ready" frisk says a little uncomfortably you can tell he is uncomfortable because you can see his worried face between his bare toes, Betty uses her illusion to trick frisk into thinking you're a squish toy
Betty looks at you and says "by the way, that question was a trap, bye bye"
Suddenly you feel an immense pressure between your head, frisk is pushing your head down on the ground with his feet at full strength, your skull is starting to give way, until suddenly, your head bursts.
Betty and frisk laugh maniacally as frisks LV increases, eventually they stop laughing
"hey Betty."
"yes frisk"
"I think I've developed a bit of a foot fetish, you don't think of me diff-" Betty shushes frisk with her big toe
"frisk, I understand, here, have a lick." said Betty, putting her foot near frisk face
"really, wow."
Frisk and Betty go home and worship each others feet
