Adam is a nice man. He's early forties, I guess, but in pretty good shape. Quite handsome, in a balding kind of way. He has a nice sense of humour, and he seemed kind and attentive. I liked him.

I fucked him.

It was what I was told to do. I did it. Duty done. Another day begins. Pass me a cigar, Martha.

He was sitting in the Portland as str8 said, looking a bit self-conscious, the way people do when they're waiting for someone. I sat at the bar and sipped a breezer, allowing my gaze to fall on him from time to time. At five past eight he dived for his suit pocket and pulled out his mobile - so considerate, leaving it on silent - and talked into it for a minute or two. The Portland is pretty small and it wasn't busy. I could hear Adam's end of the conversation quite clearly.

"Five mile tailback? Jeez, that's awful. What a pain.... No, no problem, we can rearrange... Yeah, give me a call... Nice hearing from you, thanks for letting me know... Hope you manage to get home some time soon... Bye." He put the phone away again, looking more self-conscious than ever.

"D'you mind if I join you?" I said. "Bar stools aren't too comfortable - too high for me."

"No, not at all, please." He stood and cleared his newspaper from the table, then pulled out a stool for me. What a gentleman he was. What a bitch I am. I sat down beside him.

"Couldn't help overhearing. Your mobile. Been stood up?"

"Yes. No, not exactly. Just an old friend - male - we were going to have a get-together, talk about the old days. He's stuck in traffic, can't make it."

"Too bad. I'm at a loose end too. I was supposed to be going out on the tiles tonight, but my best friend blew me out."

"Sorry."

"So looks like we're both free agents this evening."

He laughed nervously, not sure what to make of this young woman clearly chatting him up. I smiled reassuringly and ploughed on, making general conversation, trying to lure some details out of him. It was difficult at times, not letting on that I already knew something about him. I wasn't supposed to know he was single, for example, and since the norm in this society is for adults to be paired off, I should realistically have assumed he was married.

"So what will you do with rest of your evening?" I asked. "Go home?"

"Yes, probably."

"Family?"

He shook his head. "No, just me."

"Me too. Single, I mean. Tell you what, why don't we go and get something to eat?"

And with a smile he fell into my trap.

By eleven o'clock he was between my legs, licking me out. He was too heavy and brusque to be effective, but it was nice enough and I tried to lie back and forget about str8guy and the facts leading up to this scene. He was shy, and I had to undress him, slowly peeling off his shirt and trousers, kissing his chest softly and wiping my hand across his stomach. I could feel him trying to hold it in and felt sorry that he was so nervous.

"You have a lovely body," I whispered. He smiled ruefully. "Would you like to see mine?" I undressed slowly, revealing my breasts and then the pussy he had already tasted, standing before him and letting the light from my lamp fall on my skin. I could see the desire on his face, and on his cock, and I was pleased that finally he was overcoming his reserve. "Do you like it?" I asked. He nodded. "Do you want it?" He nodded again.

I pressed him onto the bed and straddled him, placing his cock against my pussy. Sliding my knees, I lowered myself and flattened my body to his, kissing him and moving my hips. I could feel his cock, hard and hot, beneath me, and I sat up to position it against my pussy. Gripping it, I slid it between my lips and let it slowly work its way inside me. Flexing my vagina muscles, I began to stimulate him and I rocked gently from side to side. I expected him to come quickly, but he didn't. At first he lay back and left me to do the work but gradually, as his inhibitions were shed, he became more involved. He gripped my thighs and buttocks, subtly adjusting my rhythms, making me speed up, then slow down, then speed up again. I could feel him moving his pelvis, adjusting the angle of his cock and making it graze against my pussy walls. We fucked like that for a good ten minutes, and my mind cleared itself of everything but sex.

It was the happiest I've been in weeks.

Adam shifted beneath me and pulled me off him, laying me on my back and resting on top of me. He eased himself between my legs and entered me again, this time fucking me more forcefully. I knew he wanted to come and contracted my muscles to help him. I pulled my legs wide apart and raised my feet in the air, making myself more exposed, allowing him to penetrate deeper and deeper. His strokes grew harder, faster, rougher, and after about a minute he began to grunt, jaw clenched, eyes squeezed shut, as his climax started.

I urged him on, scratching my nails down his back and screaming as I felt the first jolt of come burst from his cock, followed by more and more. Adam fucked on, his thrusts becoming shorter and slower until they subsided to a halt and he lay on top of me, spent.

I had done my duty.

We lay together for a while, but it was awkward. There was no feeling between us, and it was as clear to him as it was to me that this was a one-night stand. I made coffee and he left about three in the morning. I don't suppose I'll ever see him again. I hope I made him happy, just for a short while.
