“You idiot, Stevie!” bellowed Laura, her face screwed up in incredulity.

We had just returned from our country walk and pub lunch. A seemingly innocuous affair, except I had been dressed as a girl, I had been spanked in front of Amy for disobedience, and then we had encountered my GP, Dr Sam Payne, and I had ended up under the table worshiping her mucky feet. Other than that, it had been an uneventful day!

On getting home, Laura had reminded me that I had chores to complete, including ironing and cleaning the kitchen. “You'd best wear something more practical to do your chores, muffin,” she informed me, throwing me a pair of harem pants and a white T-shirt. “Take off your mini-skirt and vest top and put those on.”

She had watched as I got undressed, and, as I stood in front of her in just bra and panties, I saw her eyes open wider. Then had come her surprised outburst, calling me an idiot.

With a condescending look, she asked, “You did remember to put sun cream on, didn't you?”

She knew the answer, but I replied anyway. “Er... no, I... I didn't, Miss.”

“Look at yourself in the mirror.”

My stomach sank as I saw my reflection. Tan marks were clearly visible, marking the outline of my racer back top. Gingerly, I moved a bra strap to one side, confirming my suspicions that the skin beneath was pale, in contrast to the reddened flesh either side.

“Oh, my God!” I exclaimed.

“Well, you're going to have fun at the gym, sweetie. Perhaps that will teach you to think next time.” She was smiling, enjoying my discomfort, while I was squirming. “Just as well you spent so long under the table or else it would have been worse still,” she added, stifling a grin.

oooOOooo

I was due to go to the gym the following evening. Staring at myself in the mirror as I got undressed for bed, I couldn't see how I could go through with it.

“I can't go to the gym like this, Miss,” I pleaded.

“Hmm... I don't see why not, muffin. You can't stop exercising just because you've been stupid,” she replied. I stared at her with a look of disbelief, forcing her to say more. “Just make sure you don't take your shirt off where someone can see you. And, besides, because of your cage you always choose to shower in the cubicles with doors... you know, those for shy people.”

I sensed she was making fun of me but she was right that because of my chastity device I could never take a communal shower and I always went into one of the private cubicles.

“You're making it sound easy, Miss,” I replied. “My cage is easier to hide than my tan marks.”

“You're making a fuss about nothing. But listen, poppet, I can't force you to go, can I? You're not a slave and you have free will.”

“My sister and Zoe seem to think I'm a slave, Miss.”

“Well, you're not. So, if you don't want to go to the gym, I can't make you.” She waited for me to absorb this lifeline before adding, “Obviously, I'll be very disappointed in you if you don't go. It's hardly a sound basis for an FLR if you pick and choose what you want to do.”

She let that sink in for a few seconds, before continuing. “I might have to withdraw some privileges, muffin.”

“What... what do you mean?”

“I might choose not to flaunt myself in front of you naked, or semi-naked. You like me doing that, don't you, but I don't have to, do I? It's my body! Or I might deny you cuddling rights, or kissing rights, because you don't have entitlements to these things, do you? They are privileges awarded to you when you please me, sweetie.”

“Er... I see...” I replied. I could see only too well.

“And I might find I've misplaced the key to your device. It might take a few weeks to find it, sweetie.”

“How would you lose—”

“I'm just saying it might happen, sweetheart. Things sometimes go missing.” She paused to gaze at me, sensing my vacillation. “Would some quiet time help you think, muffin?” she asked, meaning did I wish to stand in the corner for half-an-hour or so.

“Er... no, I'll go to the gym, Miss,” I responded.

She smiled sweetly at me, saying, “I might give you a reward afterwards, sweetheart.”

oooOOooo

Laura was right that the precautions I take to hide my chastity cage from view would work equally well for my tan lines. I was worrying about nothing.

Consequently, I was relaxed on Monday evening when we both departed for the gym. As always, we both left the flat dressed in our sports gear, so I would be covered up until it was time to shower at the end of our session, and then that would be in private.

Arriving at the facilities, Laura went into her changing room and I into mine. I was alarmed to see that Dave, our regular postman, was there. It was Dave who had seen me dressed as a schoolgirl after my “detention” and, understandably, he had never forgotten that day and took every opportunity to remind me. I'm sure he was not being spiteful, but the joke was wearing thin, so I always tried to ignore him when I saw him.

Unfortunately, that evening he came over to me. “Hello, Miss,” he said in an unnaturally loud voice.

“Shush!” I hissed.

“Sorry, but I'm surprised to see you here.”

“You know I come to the gym, Dave, you see me here all the time,” I replied, wearily.

“Yeah, I know that, but I didn't realise you used the men's changing room,” he laughed.

“Oh, give it a rest, Dave. That joke is no longer funny. And I've told you, we were rehearsing for a play that day, that's why I was dressed up as I was.”

“Yeah, right,” he responded, smiling and rolling his eyes. “Anyhow, mate, I'd dress up as a schoolgirl if I could screw the luscious Laura every night. You're a lucky man, Steve, a very lucky man.”

Yes, I was a lucky man, but he didn't know the truth of my relationship with Laura, and no way was I going to put him in the picture.

We both went out onto the gym floor where I joined Laura and we both began a gruelling one-hour spin session under a sadistic instructor. At the end, I could barely sit upright in the saddle, and Laura looked similarly exhausted. She turned to me and asked if I was finished. “Yes,” I breathlessly replied, “in both senses of the word!”

I made my way into the changing room, picked up my change of clothing from the locker, and then walked into the shower block. One of the private cubicles was not in use, so I went straight in and locked the door.

Or, at least, I thought I had locked the door. I stripped naked and, just as I was about to turn the water on, there was a crash and the door swung open. Instinctively, I turned around to shield my cage from being seen but in doing so, I presented a clear view of my suntanned and marked back.

“Oh, I'm sorry,” exclaimed a voice I recognised. It was Dave again. “I thought it was vacant—oh, my giddy aunt. It's you, Steve. What the hell's happened to your back? Oh, my God! This is priceless.”

“Leave me alone and shut the door, Dave,” I yelled angrily.

“Yeah, but what's happened to your back? It looks like you've been sunbathing in... in a bikini and vest top. Have you, Steve?”

“No, of course, I haven't? And keep your voice down.”

“Then what are those lines?” he asked, a little more quietly. “Come on, you can tell me. Is this another play you've been rehearsing with Laura?”

“Yes, you're right—another play. Now will you get out, Dave! Please!”

“Oh, my giddy aunt, the guys at the sorting office are going to love this. And why don't you turn around? Have you got tits?”

“No, obviously I've not got bloody tits. Get out, Dave!”

“You're very edgy, Steve. Is it your time of the month?”

“For fuck's sake, shut the door, Dave!”

“Okay, you could have asked nicely, Steve. Don't get your knickers in a twist. I bet Laura wouldn't like you speaking to me like that. She's always so polite and sweet.”

“Get out!”

“Sorry... I'm going!”

oooOOooo

Realising I was close to thumping him, Dave left me to shower, but only after I had double-checked and treble-checked that the door was securely fastened.

I could hear Dave, still chuckling to himself, in a nearby cubicle. I rushed to get washed, dried and dressed because I wanted to be away from the gym before he did. However, I got waylaid by a student I knew from university, and by the time I could shake him off, Dave was already in the reception area. Moreover, he was talking to Laura, who had a face like thunder.

Dave smiled at me as I walked up to join them. “So, you were sunbathing in a bra then, Stevie, or is it Stephanie?”

“Keep your voice down, Dave,” growled Laura. She led the way outside, so we were as far away from other gym goers as possible.

I looked at Laura, who was still stony-faced, and she turned to me. “You had one job, Stevie,” she declared, “Which was to lock the damn cubicle door!” She shook her head, seemingly unable to understand how I could mess up the simplest of tasks.

Dave was beaming from ear to ear. “Laura's told me what you get up to, Stevie,” he explained.

“No, I haven't!” she shrieked, her eyes protruding in anger.

“You didn't deny anything,” he replied, smirking. “It's obvious that he's crossdressing and you're calling the shots. He's a sub and you're his mistress.”

“I never said anything of the fucking sort!” Laura screamed at the top of her voice. I was relieved we were outside! “I'll bust your balls if you don't stop spouting this rubbish!”

“All right, Laura, keep your knickers on—unless Steve's wearing 'em,” he mocked. “Go on, deny what I've said about you being a domme, Laura. It's plain to see. And, actually, I'm a bit turned on by the idea of you busting my balls.”

“Give me strength!” shrieked Laura.

“Just be honest, Laura. I won't tell anyone!”

Laura took a deep breath, her brain trying to decide the best way out of the mess I had created. “If you are right, and I'm not saying you are, what's wrong with that, Dave?” she indignantly asked.

“Nothing at all, Laura. I love a bit of kinkiness. Don't we all?”

Unlike me, Dave seemed to have got the better of Laura in a verbal tussle. “I don't want you telling all and sundry, Dave.”

“Why would I do that? You're not doing anything illegal.”

“Didn't you tell your mates at the sorting office about Stevie being dressed up as a schoolgirl for the play we were rehearsing.”

Dave laughed contemptuously. “Stop pretending, Laura. There was no play. And, no, I didn't tell anyone about Steve! Who would have believed me?”

Laura stared at him, unsure whether he was telling the truth. “Good!” she thundered. “It stopped you making a sodding fool of yourself!”

"Me make a fool of myself?" he chuckled.

“What is it you want, Dave?”

“I just want to join in the fun and games, Laura. What you two are doing turns me on.” Laura shook her head, but he continued, “Stop pretending there's nothing weird about your relationship, Laura.”

“Are you blackmailing us, Dave?”

“Oh, my giddy aunt, what a vivid imagination you have, Laura. I'm not blackmailing you, but I want to take part in the fun and games you two must have.”

“What is it you want, Dave?” asked Laura.

He leaned over and whispered something in her ear. I couldn't make out what he said, but Laura turned crimson and her eyes widened.

“Fuck off, Dave,” she screamed.

All I could think was that Dave wanted to cuckold me. I sprang to Laura's defence. “You'll have to fight me off first, Dave, you bastard,” I shrieked, advancing towards him.

Looking shocked, he took a couple of steps back. For a few seconds, he was speechless, but then found his voice. “What's it going to be, Stevie—knitting needles at dawn?”

“Fuck you!” I yelled.

“Leave him, Stevie,” concluded Laura, “He's not worth it.”

Smirking, Dave passed her a piece of paper. “Here's my number. Think about what I'm suggesting and if you're game, give me a call. I don't see why the three of us can't play nicely together and have a good time.”

With that, he walked off. Laura, having gone crimson, was now ashen-faced.

oooOOooo

“The bastard!” I exclaimed, when he had gone. “What a bastard he is! How dare he try it on with you.”

We got into my car and as we drove back to the flat I continued my tirade, vilifying our postman. “I'm not going to let him have his way with you, Miss. That would be assault! I will kill him if I have to.”

Laura chose to ignore my rants and said nothing, at least nothing in response to my outbursts. Instead, she remarked, “You're an idiot, Stevie. How many more people are going to find out about our special relationship? Why don't you bloody well update your Facebook status so it says you're a submissive crossdresser? Then the whole frigging world can find out in one go.”

Why was she angry with me? It was Dave doing the threatening. “I'm sorry, Miss. I thought the cubicle door was locked,” I inadequately replied.

I was driving but from the corner of my eye, I could see she was shaking her head in despair, while muttering what I took to be obscenities.

After a couple of minutes of keeping quiet, she commented, “You'd better well please me at bedtime tonight, Stevie, or I've a good mind to cane you.”

“Yes, Miss, I will please you. I feel very guilty to have let you down.” Despite feeling mortified at what had happened and Laura's reactions, my penis still managed a little wiggle at the thought of pleasing Laura.

Laura sat brooding for a couple more minutes before saying, “You've got the wrong end of the stick, Stevie! If you must know, it's you he wants to shag, not me!”

“Me?!” I screeched, the car almost veering over the central white line. “Oh, my God!” I felt my stomach sink.

“That's why I told him to fuck off. If anyone's going to impregnate you, it's me!”

“Oh, God, I didn't realise he was gay!”

“I'm sure he's not, but perhaps you've got novelty value. He sounds like a pervert to me.”

It was now my turn to sit quietly, as my brain turned over what Laura had said. I was driving on autopilot, and when I snapped out of my thoughts, I found we were parked outside the flat.

Laura spoke again. “We have to pray he was telling the truth when he said he would keep our secret.”

“Yes,” I uttered, with a sigh.

I had a strong suspicion that we had not heard the last from Dave. He struck me as being like a terrier with a bone that he had no intention of giving up.
