Maxwell leads her to the Machine Room

On her hands and knees, the bit still in her mouth with its basket hanging down, Kara follows Maxwell down a hallway and into a room marked Machine Room.

As they enter the room, Maxwell heads to a wall full of shelves with sex toys, bondage gear and machines.

"I think these would look good on you." he grabs a pair of clover clamps with a short chain between them.

Walking over he bends down to unhook the basket from her bit and leaves the clamps on the floor next to Kara "Put them on, pull a bit on the chain to make sure they are tight."

"Mhky" Kara mumbles around her bit, picking up the clamps and studying them.
'How do these even work? Ok, press there, they open... that's very knobby gripping surface... something tells me it's not for my pleasure.
Ok, place one, ouch, that's quite tight... but I can deal'

Opening the second clamp and holding it over her other small but very hard nipple, she slowly lets go until it too is squished quite flat.

"Well? Pull on the chain I said" Maxwell waves his hand at her for emphasis.

Frowning down at the clamps, Kara grabs the chain between them and pulls it straight.
Perhaps thinking she can just make them pop off, instead of giving a small pull Kara gives the chain a quite sharp tug.

With the knobbly surface and self-tightening design her pull makes the clamps squeeze harder and pull her nipples and breast out, and even with the bit Kara's exclamation of pain as she lets go of the chain and grabs her breasts is easily heard.

"I guess we can add 'not especially intelligent' to your list of weak points. Hmm, let's get the pain out of the way at once, I've wanted to test out this one for a while" ignoring the no touching policy Maxwell grabs Kara by her hair and pulls her along to the opposite wall.
'My poor boobs, that felt like my nipples got pulled off, bastard hair puller... let go, I want... wait, what is that?'

Stopping, Kara stares at some sort of contraption attached to a pair of metal pipes for balance and anchoring, the contraption itself has a motor and no obvious function and is attached to one of the pipes.
Between that pipe and the other lies a mat with a depression near the far pipe, on top of which is a smaller mat like some sort of hard pillow.

Maxwell lets go of Kara's hair before picking a long black rubber paddle with the word **** engraved in it from a shelf "This is a spanking machine, and this is the paddle we'll be using... or rather, I'll be using, on you."

"Now move to the mat, ass towards the machine" Maxwell points at the mat with the paddle.

Looking from the paddle to the machine and back again, Kara eventually crawls over to the mat.
'Rao, my heart is going a mile a minute, I wish I could say it was just fear... ouch, watch the clamps, hey, what are you doing!'
As Maxwell grabs the chain connecting the nipple clamps and pulling it and Kara down, she makes an angered "Uhat?" which he ignores completely, hooking the chain onto a small ring embedded so deeply near the far end of the mat that Kara has to turn her head to the side to avoid it getting squished into the pillow, leaving her ass raised near the machine itself.

Attaching the paddle to the machine, Maxwell lines it up so it lays across both her ass-cheeks "Now, since I know you can heal perfectly from sunlight I'm going to push the intensity up quite a bit here, I hope you mind."

Grabbing the remote he leaves the speed low but twists the strength up high before selecting a preset-program of spanks and turning the machine on.

It lifts the paddle up high, before there's a sudden whoosh of air and a loud smack.
The sudden and intense pain makes Kara scream out as she jerks her body up, forgetting for a moment that she's attached to the floor via her clamps.
Maxwell finds the way her eyes go comically wide as she feels the bite of the clamps almost as fun as the way her second scream is cut short as she throws herself back down into the mat with impressive ****.

The audible crunch as her face hits the hard pillow makes him start forward, but he decides to hold off and instead watches the machine go about its work.
As it slams the paddle down for its second spank, Kara's body makes a small shudder in reaction, but there's no repeat of her earlier jump, nor any scream.
There's just a whimper from the kneeling girl and a muffled and unintelligible attempt at calling out the release word for the bracelet.

The machine follows its preset program and hits again and again, each spank slightly faster than before but also slightly weaker.

Once he deems her ass sufficiently red and purple, he turns the machine off before grabbing some paper towels and a small container marked Blaze's pain into pleasure salve and kneeling down by a sobbing Kara
"As much as I enjoy seeing you brought low and hurt, I don't actually want to damage you... much."
Opening the container he takes a dollop of dark white to light yellowish salve on his fingers and tenderly applies it to the marked areas of her ass.

Looking at the way the engraving in the paddle left a mostly legible SL on one cheek and a VE on the other side of her ass Maxwell smiles as he widens his movements and applies the salve liberally to the rest of her ass, rubbing some of it in the cleft and across her asshole "You're quite beautifully marked, though I didn't intend to mark your face now."

Unhooking the chain from it's mooring he slowly pulls Kara up on her hands and knees, leaving her ass high and free of any more sensations, looking intently at her slightly crooked and bleeding nose, he reaches out and quickly sets it straight.
The small crunchy sound is all that's heard, as Kara just stares ahead without reaction, tears still running down her cheeks, but slowing down.

Using the paper to wipe away the blood and stopping up the side that's bleeding he pats her on the head "There you go, good as new and ready for new adventures"

At this Kara blinks a few times and turns to focus on Maxwell
'Is he insane! He broke my nose... well, made me break my own nose, I guess he set it right again, but it wouldn't have broken in the first place if he hadn't... hadn't put my ass on fire!
I can still feel it, my nose, my poor breasts, my ass! Even with that salve it's still hot and hurting like.. like... uh... well... it hurts... but... Rao, it's less now and it... it... feels good, it... Rao, it's turning me on'
