The cute, very fit, girl that had validated our gym coupon over two months ago smiled and said that she had asked her boss to upgrade our membership.

Megan shyly asked what was different than the basic level.

“It’s not that kind of upgrade. Just something that we do for people we like. People exactly like you."

I loved when my wife blushed like that at a compliment!

"You see, there’s a private dressing room. We’re not supposed to have other doors out of the regular Men’s and Women’s locker, but my boss built it himself. Corporate doesn’t know anything about it. Your new keys will work just fine, but you can’t let anyone see you use them. Just go into the showers and look for the key hole on the farthest wall from the regular entrance. Now go try them!”

Megan and I had always wondered why some people would enter the club and why we never saw them after their workouts. For some reason, my wife smiled at me and tried to tell me not to worry, in her own sexily submissive way.

“This is something that I want . . . sort of need . . . to do. It’ll all be okay. We’ve talked a LOT about this. Over and over. Perhaps we could try EVERYTHING here? Just once? Please?”

The key felt heavier than it should in my hand, and I sort of jumped when she kissed me. I jumped again when a hand grasped my already too hard cock through my workout soaked sweats. The front desk girl kissed me as well, even as she seemed to like weighing the size and heft of my erection.

Two against one.

I already knew that I was a goner.

The Men’s regular locker was as busy as I had ever seen it.

For good measure I grabbed my duffel bag and headed straight to the farthest shower area. The plastic curtain swished almost silently behind me as I didn’t even bother putting my bag down on the high shelf meant to keep it dry.

That was when I spotted the keyhole. It was just inside the shelf wall and my hand trembled as I fumbled to get the key in and give it a quick turn.

What was beyond looked just like my shower and I quickly stepped through, not wanting Megan to be alone with the rather too eager girl. The secret door slid firmly shut with hardly a sound.

I pushed aside the curtain and immediately saw Megan naked and putting on a wide leather collar around her pretty neck.

How did she get so naked so fast?

The girl wasted no time in approaching me with a matching collar.

“For a very long time you guys will have to wear these when you are in here. The number on the metal tag says that you have Megan as a partner. Now get out of those sweats and come see what has Megan so fascinated!”

Megan gestured for me to hurry up and I sighed and stripped all the way down. This time I used the private dressing room's high shelf to store everything.

The collar looked so good on Megan!

Much wider and more supple than the cheap one we shared whenever we played our occasional kinky weekend games.

My collar felt so weird as I deliberately tightened it up a few notches too loose. The girl hissed at me and came over to fit it as tight as I had ever allowed Megan to restrain me.

“There! Now you two match properly! See how much Megan’s already trembling! She can’t even think straight right now!"

It was true though. My sexy wife seemed barely able to stand up straight! Her fingers kept rubbing both her clit and the metal ring of her collar.

"Same rule for HER as for YOU though. You're safe out here. Collar or not. But if YOU, HER or BOTH of you step into that next room? Anyone WITHOUT a collar can USE either or BOTH of you! However THEY want! Don't look so shocked! They can totally possess you, but only within reason! That means if you say NO to something, they will just ask you to step back out here. No harm. No foul. Honest!"

The Sales girl chuckled a bit as Megan let out a deeply excited moan.

"My boss loves to use me to sound out the new members. Megan has already seen me naked, and playing with myself, as we looked across at each other in the regular showers. The first day she didn’t close her curtain? I KNEW that I had HER!"

The girl's dark eyes glinted a bit naughtily as she continued on in a rush.

"You have always wanted to feel my neck, breasts, stomach and pussy. I saw that easily enough when we trained together last week, but you actually seemed to like my face and eyes the best. I liked that about you! BUT, it was when I caught you staring at that new bearded Cyclist, the same way that YOU looked at ME? That's when I knew that I had YOU!”

She laughed sexily, again, and pointed at my wife's shaking legs.

“Any moment now. With or without you. Megan’s going into that room. Don't be stupid or wait too long! Tell her that it’s ok, AND that you will be right behind HER! Do it! Do it NOW! Please?”

Megan looked also was looking at me pleadingly, and I still didn’t even know what was in the space beyond the doorway.

But I just had to gesture to her, and she smiled in such relief that I still hadn’t a single clue about what had captivated her so.

The girl grabbed the little metal loop on my collar and held me still. Her finger in MY mouth tasted just like Megan so I knew that even out here I was still on safe ground.

Megan had already been in this exact situation before me.

My shaking hands shook as the girl kept her promise, guiding my fingers all over her face, neck, clothed breasts, flat stomach and then urgently down her own sweat pants. Her pussy was already warm and wet.

“Yes, Megan fingered me, just like YOU are going to do! I’ll make sure that your cock stays good and hard as we walk over to the doorway. If YOU can get me off? Before YOU go in the room, too? Then I’ll come over to your and Megan’s house next Friday, and be BOTH of your little plaything! If you don’t, and I have to take care of myself? Then you and her come to MY house as MY little pets! Deal? She's already lost, and didn't make me come, so you had better not screw up too!”

My mind was all a blur as she expertly kept me right on the edge of coming.

Then I found myself nodding and she tugged on my cock to get me moving. What I saw in the doorway totally blew my mind. Megan was already on her knees right beside the Cyclist I had so surprised myself by becoming interested in.

Worse, Megan had pointed him out recently, and had used HIM as a tool to push her own fantasies on me whenever it was her turn to be in charge.

The Boss was getting closer and closer to coming in the cyclist’s mouth, but suddenly turned around to let me see his dripping cock.

One simple point at the empty spot . . . on the floor right beside the Cyclist . . . was all it took for me to helplessly give in to the huge man.

The girl chuckled and kissed me, even as she let go of my cock that already seemed to know that I was just as lost as Megan now was.

“Remember - Anyone without a collar can USE you and Megan however THEY want, once you or her are INSIDE of that room! Only my Boss can ‘Graduate’ you to the next level. But even after that? You can still put on YOUR own collar, anytime you want, if you would rather SERVE than BE served. Next week. My place! Don’t forget it!”

My whole body shook as the Boss stepped over to Megan and presented his huge cock for HER to suck.

I sank down to my knees and shook as the Cyclist took over from the Girl to keep me hard. He knew how stunned I was, and unashamedly guided MY hand to his very long but thin cock to return the favor.

I loved watching Megan do her best to get even half of the Boss' huge cock into her throat. Over and over she tried, but it took the Giant to grab the back of her head and just FORCE it all the way down.

I was so amazed and ultra focused . . . that the feel of a warm wet slender cock at my own lips . . . almost made me cry out!

It was the Girl!

Now totally naked and smiling as she eased the rest of HER own strapless cock down my own throat.

“I decided NOT to wait to TAKE you at least! My Boss can be rather rough! So I’ll do my very best to break YOU in, everywhere, just in a little! You can thank me later!”
