Rachael had been enjoying how I was in chastity. She was reluctant at first to put me in a cock cage but after she saw how attentive to her needs I became, and how eager to please her without the need for reciprocation she came around. We had been sharing fantasies with each other and one that kept coming up for both of us was her being shared with other men. It was strictly fantasy, or so we thought. One day we decided to explore that particular fantasy a little further and see if it was something we wanted to indulge for real. We found a sex club in a nearby city and arranged for the kids to stay with a friend for the night.
"We can just go and look around, watch what other people are doing. We don't have to do anything we don't want to. If the vibe is off, we'll leave. If we want to stay and play with each other, maybe let others watch. Or not. Or maybe we'll want to play with some others. We can decide that after we get there." I said.
We had discussed it already, we trusted each other and knew our limits. I would still be wearing my chastity cage. Rachael might want me to go down and perform orally on another woman. She might decide she wanted another man to go down on her, or to suck him, or to have him fuck her. It would be up to her to decide. We had already agreed that we were ok with all of that, it would just depend on the mood once we got there.
For our evening I was in my chastity cage (of course) a black leather kilt, boots, and a buttoned shirt. Rachael was wearing black stockings and heels, a fairly short black and white check pleated skirt and a white blouse that showed off her ample cleavage. Her skirt was long enough to cover everything but the pleats made it loose enough it could easily be flipped up over her ass. Tonight she chose not to wear any underwear. The thought of her pussy exposed and so accessible had me trying to get hard in my cage the whole drive there.
We arrived at a nondescript building, from the outside there was no sign of what it was. Inside we entered a nice lobby and were greeted by a hostess who welcomed us and went over the rules. We were each handed a towel to put down and there were baskets of condoms, lube, tissues, and trash cans in every room.
We had arrived later so there were already several couples present. It was a large open area broken down into smaller "rooms" by curtain dividers. Some were more open to display, some were more private. Some were smaller for just one couple but most were large enough for several people to comfortably play in each. There was various furniture from actual beds, couches, chairs, and what were clearly benches designed for sex.
We walked around, watching several couples and groups already making out or having sex. Rachael stopped at one room with a woman being serviced by two men. She was straddling one man and he was sucking her breasts while she was kissing the other and stroking his cock. The man she was kissing was also rubbing her clit while she rocked her hips, riding the man beneath her. Rachael didn't say anything but I could tell she was turned on by what she watched. She grabbed my hand and pulled me closer, placing my hand on her ass under her skirt and kissing me deeply.
"Come on." she said, taking my hand and pulling me along to another room.
This room was unoccupied but it had a chair and a low padded bench with a raised, sloping back to recline against. Rachael sat me down in the chair and then straddled me, her skirt lifted and her pussy right over my groin. She began kissing me and rocking her hips against me. I was still in my cage and my kilt was still on so I felt nothing but my cock was straining to get hard in its cage. I could feel the frustration as the steel bars prevented my cock from achieving an erection, and yet the tight embrace provided a stimulation of its own that just furthered my arousal.
I unbuttoned her blouse further and pulled her breasts out of her bra, exposing them as I squeezed and fondled them. She kept kissing me hungrily and grinding her hips against me.
"Strip." she said, suddenly standing off me.
I unbuckled my kilt and let it drape over the chair beneath while taking my shirt off. Rachael had reached in and removed her bra, her breasts now free and framed in the open buttons of her blouse. Once I was naked she sat back on me again and brought one of her tits to my face.
