Yeah, she thinks with her crotch

Forgetting all about Blaze, Kara lets Harley pull her the rest of the way to the top of the stairs, stopping at the top for yet another make out session, this time Harley focuses her hands on Kara's breasts "I'm a hands on kinda gal supes, and this suit is way too thick to my liking... let's find that room and get naked!"
"That sounds.. mmm, that sounds great, I want to taste you"

Spurred on by Supergirls words, Harley looks around and sees a hallway off to the side with a symbol not unlike their token stamped above its entrance.
Before they can enter it though, a giant of a man in a black suit steps in their way "Sorry gals, this area is for Mistress Blazes special guests only."

Demonstrably pulling Kara against herself, and constantly running one hand across her body, Harley holds out the token they received with the other one "You mean special guests like us?"

Giving Kara an admiring once over, the man looks at the token and nods, before stepping to the side "Indeed, your room is the one at the far end, all amenities provided by Blaze's in cooperation with The Gilded cage"

Moving even faster forward, the two girls almost run the last bit to reach the door "If I remember correctly, the symbol on this token means 'favour', I wonder if she thinks we owe her one now... oh well, judging by this set up any favour asked is gonna be a hell of a lot of fun, and if it isn't then it's time to bring the hurt."

"I... yeah, I'm not too hyped on doing anyone any mystery favours, but that sounds a lot like a problem for future Kar... um, future care problem... thing, uh... wow, that's a sex room"
Stepping slowly into the room, Kara doesn't even notice Harley locking the door and dropping a steel bar in front of the door, too busy staring wide eyed at the rest of the room.

The centerpiece is the bed, which is round and big enough to handle four couples without anyone touching who doesn't want to, the bed spread, floor, walls and parts of the roof all remind her of film scenes from brothels only cranked up to 11, with the floors being plush, the walls and roof with plenty of mirrors and the bed itself with black silk sheets.
The exception to the mirrors is the wall on the side of the room that's covered in shelves filled with sex toys of all sorts from pretty standard vibrators, strap ons and butt plugs to some whos purpose Kara has no idea of and can't even begin to guess at, as well as copious amounts of BDSM equipment aimed at both restraint, denial, pain and anything in between.
There also seems to be a lot of D rings and some straps or ropes hanging down from both the ceiling and the walls as well as what can be described as some sort of fucking machine in a corner.

Hearing a clinking sound behind her, Kara turns around and sees a table on each side of the door, one filled with bottles of assorted drinks, chief among them a giant bottle marked 'XXX' and a sign saying "For drinking" and the other table filled with other bottles and cans that seem to be everything from oils to chocolate sauce and whipped cream and a sign that says "For playing".

"Wow, this is... a lot, I've got no idea where to start, except with you and... oh, thanks I guess we start with a toast, to a long and fun night, bottoms up"
Looking at Supergirl with a look that's a mix of fond and exasperated Harley raises her glass "Oh supes never change; to fucking your brain out until you can't think straight, your cunt so well it'll be drooling for a week and your ass until you can sit on a beer can without noticing, and yeah, bottoms up!"
"Oh... I'll... uh, I'll wreck your va... pussy and ass too, I'll fuck you until you've come so much you beg for mercy!"

Looking very pleased with having said all that almost without blushing, Supergirl takes another look around the room, now with x-ray vision.
'I need to slow down on those XXX shots, every one I take seem to make me twice as horny as the last... or maybe that's just my partner here, she's like sex on legs... very very sexy legs... huh, the lightbulbs and wiring here seems weird, is that some sort of mood lighting, and I think optical fibers? Weird."

Pulling Supergirl with her onto the bed, Harley starts fondling the sides of her costume again, worrying at a zipper that seems impossible to get loose "Enough talking, now show me how to get this thing of, I want us to get naked and stick my tongue up your every hole and then test out some of all the fun stuff in here"
Enthusiastically kissing Harleys neck and pulling at her cleavage, Supergirl nods and guides Harleys hands back to the stuck zipper on the side and as soon as Supergirls fingers touch it, it seems to pop loose on its own.

In the control room, a smiling Blaze looks out at a row of monitors that show Supergirl and Harley from multiple angles, all of them with a [Rec] in the corner.
