I met Lydia from a posting on craigslist. I was in the habit of posting a variety of ads every week in the casual sex section, trolling for playmates. Sure, the odds of getting a date out of an ad were low, but what was the cost? And there was something addictive about the unknown, the excitement of new possibilities coming your way.

This ad was straightforward, something to the effect of "Handsome man would like to be your escort to a sex party." It was a basic plea for a woman who wanted to explore the sex party world of San Francisco, but needed a guide. I would escort her, pay any fees, and would expect nothing in return but the chance to get into parties where you needed to be a couple or a single woman. Of course, I hoped for more, but no need to make that explicit. If the chemistry was right, who knew?

Anyway, Lydia responded quickly, and after a bit of flirting on email, she sent me her epic and her number. I called and we arranged for a drink that night, to get to know each other a bit. We agreed to Mecca, a sort of upscale bar, full of beautiful people of mixed sexual orientations.

Well, that drink let to quite a fun evening. What started out as whispering to each in the bar led quickly to passionate kisses and groping, and before too long we headed out to the power exchange for her first foray into a public sexual play space.

Lydia is about 45, blond, large breasts, nice grabbable ass, kind of a slightly fucked out MILF look to her. Sort of slightly slutty soccer mom look. She was recently separated and enjoying exploring her sexual passions.

As for me, well I am a bit of a freak. Married to a sexy woman how I rarely have sex with, I instead have been using public venues to indulge my desires for submission, humiliation, and cuckolding. My wife is not into this kind of play and so I have been looking elsewhere for it for years. I look pretty alpha male, muscular and tall, but inside am pure sissy.

Well, anyway, that night at the power exchange was hot. I probably spent an hour eating Lydia out while groups of guys watched and jerked, and then we invited other men into fuck her. I could tell Lydia, who did not know what I was looking for exactly, was a bit surprised by the submissive role I was taking, and by the fact that I seemed to be getting more pleasure out of kissing her while she fucked others then by trying to fuck her myself. She did seem to enjoy the various guys entering her, and all in all, it was a lot of fun. We parted for the night and agreed to set up a date for another sex party.

Lydia knew of a private party, and after some research, I tracked it down. It was a costumed event, so Lydia went shopping for a sexy corseted gown, and I got myself tricked out in sub gear, all in PVC and leather complete with a collar and dog chain. We agreed to meet for a drink the following Saturday right before the event, to get geared up for the evening and to discuss our wants for the party.

What transpired at that party was a cuckolds fantasy come true, and I sit her the next day typing this, my mind still blown, not knowing if she will ever talk to me again.

So I met Lydia at a bar near where the fetish/sex party was going to happen. She was dressed in a tight rubberized little blue dress, with a cute fringe of feathers. For myself, I was in leather pants and vest (I had a collar and wrist and ankle cuffs that I would put on at the party).

We had a drink and chatted a bit about the party. I slowly felt myself dropping into sub space, and before too long we went to the club. It was a Spring Fling party, with people dressed as fairies and elfs and warlocks and goats and god knows what else. As soon as we were in the door, I put on my collar and leash. Lydia gave me a little smirk, grabbed the leash, and led us on a tour of the rooms.

Things were pretty quiet, but it was clear the back room was where the action would be. There was a bed in the middle of the room, and along the side were lots of benches for sitting, playing, and watching. We sat on a bench, and talked a bit. There was a woman and two guys on the bed opposite us. I began to caress Lydia's legs, our lips met for a kiss, and before long I was on my knees between her legs, her dress up, her panties pushed aside, with my tongue buried in her shaven pussy.

I lapped and lapped, not sure what was going on behind me. Lydia is loud during sex, and she moaned and guided my head. After a bit, my head slid down her legs and I began to lick her shoes. I was on my belly at this point, her sitting above me, and who knows what happening behind me.

After a bit of this Lydia jerked my chain up so I would sit next to her. She led me over to the bed, where the woman was lying on her stomach, rubbing the cock of one of the guys through his jeans, while the other guy was licking her breasts. Lydia immediately began to kiss the girl, and while I kneeled next to the bed began to rub the cock of the other guy through his jeans as well.

Up to this point, while sub, I was not pathetic. I could have joined into the fray her, and been an equal partner for the night. I think Lydia thought I was going to. But no, that was not for me. Instead I bent my head down and began to lick and tongue the asshole of the girl lying on her stomach. She was pretty, petite, youngish, and totally non-plussed by what I was doing. I could have been a fly on the wall for all she cared, as I spent maybe 10 minutes tonguing and sucking on her asshole. Meanwhile, clothes were coming off everyone else, and when I finally stopped (because the girl rolled over and began to get up, without even giving me a glance, Lydia had the cock of one guy out and was rubbing on it.
