She was in a tiny room, not much wider than her outstretched hands. It was dominated by a large horizontal X frame about four feet off the ground. Well, it wasn't quite an X exactly because it had a straight piece in the middle to support her torso and head. It wasn't standing on legs but instead was attached to large circular plates set into each side wall. It had lots and lots of straps.
Above the frame on the ceiling was some kind of track, it kind of looked like a railroad track, which ran to the back wall. Which was only a few feet away. Rebecca couldn't figure out what it was for.
She could hear some kind of thumping noise in the distance, but it was muffled and she couldn't tell what it was. The lighting was soft, and the room pleasant despite it's small size.
Nexus was the premiere consensual abduction service in the country. The trick was you couldn't just show up and be taken in. You always had to go through a series of challenges. And, every time you wanted to enter, the challenges became more difficult. Some were quite elaborate, like a treasure hunt involving many steps. Rebecca remembered fondly her very first adventure, when she first locked her boots together, then her hands behind her back, and then had to shuffle slowly in bondage across the mall and out into an office building. How quaint that experience seemed now!
Today however she'd merely stepped into a limousine and been brought here. Through the mirrored windows of the limo she'd only seen that she'd been taken to a very large building of some kind, and then she'd entered the room.
Hanging beside the door was a spider gag, which she eyed with disfavor. Rebecca preferred gags that blocked all noise, so she could only whimper. But she could only choose to follow the instructions or give up and go home, so a spider gag it was.
Behind the gag was another note which said to take off all her clothes and to strap herself down to the frame. Well, that was a surprise! Giant X frame, lots of straps, who would have guessed that she was going to tie herself down to it?
Somewhat grumpily, she pulled off her beautiful boots (the same ones she received in her first adventure!) and got undressed. There hadn't been any hobbling at all this time.
With some difficulty, Rebecca managed to haul herself up on the X frame and then inelegantly flop over on top of it. Why the fuck was it so high off the ground anyway?
The attachment points for her legs were on the far side of the X, closer to the rear wall. She lay flat on her back. Underneath her rear the frame ramped up so that her pelvis was tilted, giving even easier access to her clit and vagina. The part of the X supporting her legs angled up under her thighs and then angled down under her calves, so they were comfortable even with the ramp.
There were straps that went around her ankles, calves, thighs, waist, above and below her breasts, on her arms above and below the elbows and around her wrists. There was an elaborate head harness which quite firmly held her head against the frame: she could neither lift her head nor turn it from side to side.
She got everything strapped down except for her right arm, and then managed to wiggle that arm through the strap loops. Beneath her fingers was a lever which tightened the straps around her arm. She pressed the lever click click click until the straps around her right arm were as tight and snug as all the other straps around her body. After the last click the lever depressed and didn't come back up again. Clever, she thought, she could thrash about as much as she wanted and there was no danger of accidentally continuing to click the lever and having the straps tighten too much and cutting off circulation.
Rebecca tried some experimental thrashing. She was pinned down good and tight, unable to move at all in any direction.
In her position with her feet towards the rear wall and her head strapped down, she wasn't able to see the entrance door behind her. She imagined it softly opening. Someone could walk in, duck under the X frame, and be standing between her legs. She'd be completely helpless under their hands and tongue, unable to even intelligibly beg for them to stop because of the gag, unable to stop them from giving her orgasm after orgasm...
Or maybe a giant vibrator would come sliding in on that mysterious track on the ceiling...
Rebecca waited. Nothing happened.
Nexus very strictly observed boundaries and limits. Rebecca personally didn't like pain, so she had declined all the available masochism options. Never in all her adventures had any of her declared limits ever been crossed.
But merely because she had said that she allowed herself to be sexually stimulated while in bondage didn't mean that she was going to be. It would be perfectly within the rules for her to be stuck here for the next five hours, not able to even masturbate.
Rebecca sighed through her gag. Maybe it was time to revisit her masochism limits? Some tickling wouldn't be too bad. Or maybe even some light spanking? Hell, how about a bit of hair pulling? She wiggled on the frame, just to give herself something to do.
She wished there was a "fast forward" button she could press, to move things along...
With an electric whir, the round plates in the side walls rotated, and the X frame was flipped over. Rebecca found herself hanging beneath the frame, still tightly strapped to it. The rotation continued about thirty more degrees, so that she was slightly tilted upwards.
"FUCK!" she said, which came out more like "UCK!" because of her spider gag.
Well, gravity did give her breasts a nice shape, she had to admit... maybe someone would come in and nibble on them?
With a deeper whine, the frame was pulled up to the ceiling, and with a THUNK attached itself to the track. The whole frame then slid on the track towards the rear wall.
"UCK!" said Rebecca again.
The rear wall slid aside and Rebecca's eyes went wide. Sound washed over her. She started to violently struggle, crying out "O O O O!"
On the other side of the opening was the inside of a domed stadium. Ten thousand people were dancing on the floor in a massive rave. The thumping noise she'd hear earlier was the music, muted by the sound proofing of the wall. There were fog machines and colored strobe lights.
The track continued UP the curved ceiling of the dome. With a whir, Rebecca found herself moving towards the top of the ceiling. Scattered around the dance floor were giant screens, all showing close-ups of her bound body. The crowd roared with approval.
Rebecca was petrified. She really would have liked to struggle tremendously, and she knew there was no chance she could get free... but if somehow she did rip free... it was a very long fall.
She hadn't put "don't suspend me three hundred feet above the floor" in her limits BECAUSE IT HADN'T OCCURRED TO HER THAT SHE MIGHT BE STRAPPED TO THE CEILING OF A GIANT STADIUM.
"UCK! UCK! UCK!" she said.
At the top the track didn't stop, but continued down the other side of the curved ceiling. A little further down the track was suspended from the ceiling, in loops and curves, like a roller coaster ride upside down. The frame slid down the track, gathering speed.
"AAAAAAAAAAAAAA!" Rebecca screamed.
After many loops and curves the careening frame finally slowed and slid to a stop just above the upstretched hands of the roaring crowd, with Rebecca still strapped beneath it, facing downwards. Some people found that by jumping up they could just touch her breasts. One woman climbed up on the shoulders of a man beside her and greedily buried her mouth in Rebecca's pussy. Inspired, others also climbed up on each other and began licking her breasts, her ear lobes, her toes, whatever they could reach.
Rebecca could feel her orgasm building... building... building...
With a click and a whir, the frame started moving along the track again.
Desperately the woman clung to the frame and remained glued to Rebecca's pussy. Rebecca's orgasm exploded, washing over her. The woman slid down into the waiting hands of the crowd below.
The track made a spiral twist and Rebecca found herself lying on her back again, now on top of the frame instead of hanging beneath it. The frame whirred forwards to the giant stage at the front of the room, and came to a gentle stop in the middle the stage floor.
Rebecca lay and quivered.
Every screen on the dance floor showed her bound, naked, helpless body, quivering.
An amplified voice thundered, "And tonight's winner is -- DAVID FENWICK". A happy man bounded up onto the stage to cheers and applause.
He walked over to Rebecca and whispered in her ear, "Do you know why the frame tilts your pelvis up like that?"
She tried to shake her head, but couldn't move within the harness.
"It's because when I slide my fingers in like this... they slide across the top of your vagina... right on your G-spot..."
She lost count of how many orgasms he gave her that night.
