It started as a fairly normal day. I was in the cafe opposite my office finishing my flat white. I grabbed my bag to check my lipstick and went to stand up. Then my phone buzzed. It was a message. From Matt. To the assistants group on whats app. 

"I need a little help with an assignment this evening. Short notice I know. Any volunteers ? " 

"Oh it's a bit naughty...."

I put my phone back in my bag and wandered into work, now totally distracted. I sat at my desk, staring at the blank screen in front of me. I couldn't concentrate. It was getting worse. The more shows I did the harder it was to settle down to the mundane rhythm of everyday life. Writing an obituary about a former mayor just wasn't holding my attention. All I could think about was the spotlights, the outfits, the blades. I felt my face flush and I wriggled in my seat. I checked my phone again. No one else had answered. Damn it. I guessed Lisa was, er tied up, as she usually covered all the more unusual things Matt got up to. Which got me thinking again. This time about limits. And where mine were now. Looking back at what I had done, how much I had shown, and what I had enjoyed I had to wonder what Matt had in mind that had prompted the warning. And that begged the question whether it was a warning or in fact a challenge. The word assignment just added to the intrigue.

"i'm in...." I pressed send and it was done.

I was becoming painfully aware at just how good Matt was becoming at pushing my buttons. The work day had dragged terribly. I escaped for home as soon as I could, showered and fixed my hair and make up. Matt had emailed me some details. Not many of course, but some. And the thought of following them had been driving me nuts all day. I was to wear a black leather coat that had materialized in my flat while I was out, and some black high heels. And that was it! He wanted to me travel to the venue naked bar an overcoat. just a few months ago, I would have been outraged. Now I was terrified but excited. Could I really do that ? Would I get found out? 

I slipped on the shoes, which were high enough to draw attention then tried on the coat. It came down to my bare calves. I wrapped it around my lightly tanned body, clad in nothing but a spritz of Chanel and tied the waist belt. No buttons. I took a deep deep breath wondering what on earth was becoming of me and did a twirl in front of the mirror. At first glance I looked normal enough but it was clear any movement quickly exposed a flash of leg, thigh or cleavage. For a moment I considered putting a stop to the madness. No more flashing the flesh, no more shows. But i knew I wasn't being honest with myself, my needs and with a final glance in the mirror I  headed out the front door. The drive across town was totally nerve wracking. My Audi sits low and the coat fell open over my bare legs with each gear change. I was certain every high riding vehicle could get a view all the way in. When I finally reached the parking spot reserved for me I was dismayed and excited to find it was a ten minute walk to the venue. I climbed out of the car carefully keeping my legs together, moving smoothly.  Walking through busy streets with the chill spring air creeping into the coat was more thrilling than I could have imagined. As the breeze tugged the coat away from my bare legs with each stride I wondered who was looking, if anyone had guessed. It was a worry that it was so much fun.

I waited nervously in the shadows, heart pumping. I was no longer sure if I was excited or was having an anxiety attack. I wasn't in a changing room but the lobby of an old basement nightclub, looking out from a side door. At one side was the entrance to the gloomy club, the other side twenty yards or so away were a couple of ticket windows, all dark wood and brass. It was somewhere between retro and seedy. People were starting to file in, groups of men, couples, forming queues at the still closed ticket booths. As usual I had no idea what was going to happen next.  As far as I could tell what was not going to happen was a magic show as such. Apparently on the bill was a burlesque and strip show themed fund raiser and I was there to help with the collection. That was all i knew.

What I certainly did not expect was Lisa to stride into the centre of the lobby. She was dressed in thigh high leather boots and a black leather cat suit, the front unzipped to her navel displaying a generous helping of oversize cleavage. She looked amazing. For a second I was jealous and a little turned on, then it struck me, if she was here after all why did Matt need me ? 

"Quinn".

It wasn't an introduction, more an instruction. I surprised myself when I I stepped out of the ante room and strode towards Lisa with a confidence I didn't feel. 

"Strip"

This time I did pause for a second. I tried to hold my confident smile but I am sure it wavered. I glanced around, there were maybe a hundred people in the lobby already with a queue forming outside. Could Lisa be serious ? Here ? Now ? I took a deep breath and undid the knot in my belt. I pulled the coat open arms wide to reveal my naked self beneath, turning around slowly to make sure everyone got an eye full then shrugged it off my shoulders letting it slide down to the floor. Gaining confidence from the astonished and admiring glances I kicked off my shows and looked at Lisa expectantly.

The next few minutes were as terrifying and exciting as anything I had experienced involving a blade or sword. Lisa directed me in cold harsh tones , quite different to Matt's usual style.

"Stand here. Back to the pillar." 

I stood with my back to an old wooden column which ran floor to ceiling in the centre of the open space. It was narrower than my shoulders and I could feel its uneven surface against the bare skin of my back. Lisa had a box of equipment by her feet from which she selected a semi circular metal collar. I leaned harder back into the wooden post as Lisa stood in front of me holding it up around my neck. With a few smooth moves the wide metal band was bolted to the post and I was secured in place. 

Lisa took a step back to admire her work. Stepping forward again she took my right wrist and pulled it  down and behind my back. I could feel her impressively augmented chest rise and fall as she pressed into me pulling down more before securing my wrist with another cuff bolted to the side of the beam. Her hips brushed mine. She leaned in, kissing my neck as she locked my left wrist in place too, my hands a little lower than would be comfortable given the rough finished metal under my chin. 

Smiling at last Lisa kissed me again, this time on the lips. Then at the top of my breasts. I knew I was blushing, my breathing deep. I had never kissed a girl before. Or been kissed by one. And now the brunette with the impossible body was kissing my taut tummy. My left hip. It felt so..... Was she going to kiss me... there ? I daren't breath. I had forgotten we had an audience. I had forgotten I was straight. I could feel her lips brush my thigh. Then she pulled my feet apart a little and a pair of manacles locked them in place too, shoulder width apart.

Rising once more Lisa ran her fingers slowly up the inside of my legs . I arched my back as best I could, I wanted her fingers to be braver. Instead she took a length of  twisted metal wire with a loop at one end from her box of goodies. She lent in once more, her tongue playing my with earlobe as she fed the wire behind my waist clipping it to an eyelet in the back of my neck under the collar. I was still confused by her actions and my feelings so it was a shock when she fed the other end of the wire between my legs and pulled it up so it bit through the embarrassingly wet folds of my pussy and pushed down hard on my already throbbing clit.

I moaned as she took a step back. I can't tell you if it was because she moved away or because of the pressure from the wire. She reached up and a pulled down a chain suspended from the darkness of the ceiling and using a metal shackle secured the end of the wire to the chain. each tug causing it to bite deeper. By now my legs were shaking. I wasn't thinking straight enough to wonder where the chain went. But as it happened I didn't have long to wait. A light was played up onto the ceiling and revealed the chain running around a pulley . Lisa clicked her fingers and the free end fell down to her waiting hand. She looked into my eyes for a second or three, making sure she had my complete attention before giving the free end of the chain another tug. I whimpered and  writhed but I couldn't move enough to ease the pressure between my legs. I wasn't sure if the sliding action my wriggling created felt better or worse. Oh god. Better ? I rocked my hips some more. 

What was happening to me? Turned on by Lisa ? Trying to rub myself to an orgasm on a metal chord in a room full of strangers ? It was no good , I couldn't think, I just needed to twist and rock a little more , and if I closed my eyes and think about nothing else maybe I could... I cried out. The pressure had increased again. My eyes snapped open. Lisa had hung a bucket from the free end of the chain. A big, heavy metal bucket. With a label. Donations. Oh. My. God.

Within moments the first coins began to land in the bucket hanging a few feet in front of my waist. I was aware again of how busy the room had become, so many people. I alone was naked . Just me being tormented. Each coin weighs next to nothing. But I could imagine that a bucket full of nickels and dimes would weigh a fair bit. I was panting now, mouth open wide. Crowd pressing in closer around me. Lisa was playing the audience like the expert she was. 

"Sir, yes you? She's lovely isn't she? Stick a $10 in the bucket and you can feel her tits ...of course, she loves it..... how about you Ma'am, want to pinch her nipples for $5?"

There was nothing I could do but suffer. Or enjoy? The bucket was filling slowly, notes and coins. It was biting ever deeper, and every nudge made the bucket swing. By now I was glistening with perspiration, panting hard for breath. A sleazy looking guy in a leather waistcoat offered Lisa $100 if she would take off her cat suit.

"Well its all for a good cause. Ok, as long as you pay in coins ...!" 

Moments later he was back with a cloth bag of coin from the bar and he dropped it into the bucket with a flourish. I cried out as the extra weight hit, and then had to wriggle helplessly as Lisa treated the crowd to a skillful striptease, sliding out of her boots then the tight leather suit in an incredibly sexy show I could only dream of emulating. Her figure was unbelievable and even though I knew it was more than a little magically assisted I found myself a tiny bit jealous of that too.   Could I really be imagining myself transformed into a living barbie ? And then Lisa was back, close, I could feel her breasts press against my hips as I looked down to watch her take my right nipple in her mouth, her teeth. 

She licked and flicked and bit and sucked. It was so .... amazing. So good. Once my nipple was throbbing, rock hard she switched sides, leaning across me.  I was getting so hot, so flustered. And then she stopped. With a wicked grin and a final kiss on each side she produced a pair of nipple clamps. Moments later their cool metal teeth were biting into my rock hard flesh. I whimpered. By any sane measure I should want this to stop. But I wanted the exact opposite. Even when Lisa connected the nipple clamps to the chain
in front of me with a length of chord. It was tight and would get tighter as the load from the bucket increased. The bucket. Lisa's show had had the inevitable effect. The bucket was filling and coins seemed the weapon of choice!

And then the doors to the auditorium swung open and the crowd surged forward towards the doors. I was felt and groped from all sides. More loose change hit the bucket, and a lot of paper money too. A few long minutes later and I was alone in the lobby except for Lisa and the door staff. She had a naughty smile which made me a little nervous. She dangled a red ball gag in front of me and I found myself opening wide without a moments hesitation. She pressed it gently into place behind my teeth then buckled it tightly. 

"Enjoy the show ... " she smiled and nodded at the grainy black and white monitor on the wall.  I moaned loudly, she could not be serious? She couldn't  leave me like this. My crotch was on fire, my nipples felt fit to explode.  I shook my head no, but to no avail. She was gone. The show was a mix of vintage and burlesque classics. It seemed to go on forever, but I wasnt really interested. There were stragglers coming through all the time, most of who paused for a grope and a donation it seemed. Looking back it must have been some magical influence which meant my predicament remained a deluge of excitement and frustration rather than descending to cramp ridden agony. Finally the show on the little screen looked like it might be coming to an end. And it dawned on me that everyone would be coming my way once more on the way out, probably a few drinks merrier. 

And then Lisa was back. She was carrying a small wooden stool which she set on the floor under the bucket. I moaned loudly and tugged on my restraints but she was unmoved.

"Ready Frank"

A heavily muscled guy appeared. But all I could see was what he was carrying. It looked like a cannon ball, a dull metal sphere with a short chain at one end. It appeared to be very heavy. Moments later it was balanced on the stool and Lisa had shackled the chain to the matching one just above the handle of the bucket. 

"Ladies and gentlemen, remember that this is all for a good cause. Turn out your pockets, empty all your change, and if we fill the bucket tonight you will get to see what happens if we kick this stool away...."

My muffled protests and wriggling were met with applause and laughter. I was really not sure I wanted to find out what would happen if all that weight landed on my poor tortured pussy. But the trouble was the movement, the new coins being thrown into the bucket, the attention, was just making me hotter. The crowd were bolder. I was felt up from all angles. It was all getting a bit overwhelming when Lisa made a space and stood hands on hips in front of me.

"Three ...............................two .............................one.........................." and she kicked the stool away.

I screamed around the gag. The wire running between my legs was already totally tight. Now it felt like it was biting into me. The clamps couldn't take the strain and jumped off my nipples which exploded in a sexy kind of pain as the blood flooded back. Time seemed to stand still. The crowd went quiet and stepped back, a couple of people flinched. Then there were a couple of screams. My hips were on fire. I was shaking, ready to cum, ready to pass out. Then I caught sight of the weight and the bucket. They were sinking, slowly but noticeably. I looked down, and the wire seemed to be higher up my.... and then there were more screams. I could feel the wire slice through me up past my navel, I could see it rise up between my breasts. The weight hit the floor. The wire reached the base of my metal collar. I looked down. I was cut through from pussy to neck. Then I passed out.
