I realised I was fidgeting, so put my hands on my lap under the table and looked around..

The food court was mostly empty, with the lunch rush likely to start in an hour or so. We had decided that this would be a good place to meet - public enough that no-one would feel vulnerable, but quiet enough for privacy.

I looked around again. Still nothing. I checked my watch and realised they were only a couple of minutes late. To give myself some time to collect my nerves I’d gotten there early, so had been waiting for a while already.

I had been browsing through a dating site I belong to when I noticed the ad in the Personals section: “Sexy sub needed”. Out of curiosity (or so I told myself) I clicked on it. “Sub male needed to satisfy a horny couple. Must be bi with a willing mouth and ability to comply”. The photo accompanying the ad was of a woman in a leather corset, kneeling, wearing a blindfold with a ball gag in her mouth.

Years ago a friend and I got really drunk and after a number of dares we ended up sucking each other’s cocks. But that had been a one-off and since then I had only been chasing after girls. I guess I occasionally thought about that night but never made any effort to try that sort of thing again. In the end I clicked off the ad and moved on.

A few days later I was back on the site found myself looking at that ad again. I re-read the description - “bi with a willing mouth”. My mind went back to that night all those years ago, and I recalled  the sensations - the smell of his sweaty crotch, the feeling of his hardness in my mouth, the taste when he blew his load. I had never admitted it to myself, but I had enjoyed giving that blowjob almost as much as I ever had receiving.

I decided to reply to the ad.

I didn’t expect much to happen, but the next day there was a new message in my in-box. “We’d like to meet you when are you free?” We exchanged e-mails over the next couple of days and arranged a suitable time. And that’s how I found myself waiting at a food court on a Thursday morning, wearing a distinctive orange shirt, waiting for a couple wearing blue, trying not to fidget.

“Matt?” came a male voice behind me.

I turned. The voice belonged to a tall, slim man wearing a navy blue t-shirt. Next to him was a woman wearing a pale blue sundress, with small breasts and toned calves, her hair in a loose ponytail.

I stood and we shook hands. I already new their names - Steven and Jocelyn - but knew that if things proceeded I would end up referring to them as “Master” and “Mistress”. He was a little taller than me, she a little shorter. We sat and started to get to know each other.

They explained that they had been married for seven years, and for the last couple of years had been exploring the alternative sexual lifestyle. Initially that meant having threesomes with other women, but over time they started swapping with other couples and attending swingers’ events. Both were bi. She was submissive but sometimes liked to take charge with other women and now they were looking for a man that they could both dominate. They had tried with someone last month, but he had only really been interested in banging Jocelyn.

“Tell us more about your experience, and why you think you might be what we’re looking for” she then asked.

I described that episode from all those years ago, adding that I’d recently been thinking more and more about blowing a guy. I told them about my last relationship, how a couple of times I had asked my girlfriend to use a dildo up my ass. I really enjoyed it but she thought it was weird and so I stopped trying for more, but missed the sensation of being taken and being at the mercy of another. That last bit made them smile at each other.

“That sounds promising,” said Steven, “but how do we know you can be the type of submissive we’re looking for?

I paused, sensing that this was about to become more of an audition than a meet and greet.

“You know,” Jocelyn said to him, “we should see how far he’d be willing to go right now. Didn’t you say you needed to go to the bathroom?”

He smiled, nodded, and got up.

“You should go with him,” she said, “and make sure you can show me what a good boy you are.”

I sat there, trembling, slightly, looking at the two of them. Eventually I stood and followed Steven towards the bathrooms.

We walked into the men's room, which was empty. He went to the disabled cubicle at the far end of the room and motioned me inside. He closed and locked the door. I was breathing heavily.

“On your knees, slut.”

Slowly I knelt down in front of him. His crotch was in front of my face, and I could see the bulge within. I reached up and undid the button, then pulled the fly down. His trousers fell around his ankles, then I hooked my fingers over the elastic of his underwear. I stopped, but then thought “fuck it” as I pulled his underpants down, freeing his cock. It sprang forth, the head nearly slapping me in the face. I looked in wonder.

He was a bit bigger than me, and circumcised The shaft was thick and veiny and the tip was bulbous, and the pee hole was staring back at me. He was shaved, and his hairless balls dangled between his legs.

Realising that I needed a gentle push over the edge, he whispered “get going, cock whore”.

I reached up and took the shaft in one hand, it was warm and firm. Opening my mouth a little I poked out the tip of my tongue and started to lick the smooth head. He murmured in appreciation. I started gently pumping my hand up and down, as I opened my mouth further to take in the whole of his cock head, sucking as I jerked him off. As I became more involved my head started to bob up and down, taking more and more of his length inside me. He started to thrust his hips in time. Eventually about half of his length was inside my mouth.  I pulled him out and licked the underside of his shaft, from the base to the tip, swirling my tongue around the tip for good measure. I thought of all the times I’d watch women give blowjobs in porn films and I tried to copy them. His cock was becoming slick with my saliva.

The thought that I was in a public bathroom sucking a stranger’s cock was incredibly arousing, and my own cock was rock hard. My hand let go of his cock and I tried to take all of him into my mouth. I got about two thirds of it down before I started to gag, and so pulled off him and focussed my attention instead on his balls, licking and sucking each one as I my hand slid up and down his shaft.

I returned to sucking his cock and soon he started breathing faster. I squeezed the shaft harder as I increased the action of my tongue on the head. “Remember that Mistress wants to know” he gasped.

Pumping his cock faster and faster I could feel him swelling more inside my mouth and suddenly he grunted and pushed his hips forwards as a gush of jizz spurted into the back of my throat. I swallowed the first wad, but the subsequent squirts I held in my mouth. Once he was finished he pulled out of me and got dressed. There was a trail of cum running down my chin, which I wiped off with my fingers. Keeping my mouth shut I stood and we both walked out of the still-empty men’s room.

We walked back over to the table, where Jocelyn was checking her phone. When I reached her I bent down and kissed her on her lips, pushing her husband’s cum into her mouth. Then I sat back in my chair.

Jocelyn swallowed and licked her lips. “Well, I think we have an answer,” she said. “And I think we’re going to have a lot of fun with you.”
