Chapter 1

Kevin slammed down his glass in anger.

He knew it had been a mistake to come to the reception, and Arabella’s behaviour was already proving him right. He looked across the room to where she was standing much too close to Dave Costello, her wine glass at a tipsy angle, giggling at some inane remark he’d just made. He saw Dave glance down at Arabella’s ample chest, her embonpoint almost spilling out of her low-cut black cocktail dress. On some women it would have looked elegant, but Arabella managed effortlessly to make it appear slutty.

Kevin acknowledged grimly the implications of this observation. It wasn’t the dress that was slutty, it was his wife. He remembered her comment when he’d suggested she should wear a bra underneath: accusing him of being a prude, and that underwear of any sort just spoilt the “line” of the dress. He knew she just wanted men to look at her boobs, and if there was an opportunity to reveal her lack of panties as well, that would be even better.

“Don’t you want me to look attractive for our friends?” she had asked rhetorically. Kevin had been tempted to point out that (a) he didn’t know most of her work colleagues; (b) the ones he did know seemed to be arrogant arseholes; and© there was more to looking attractive than flashing your knockers all over the place. But he’d wisely held his tongue.

Dave Costello would presumably have disagreed with point©. While still gazing at Arabella’s boobs, he casually swiped two full wine glasses from the tray held by a passing waitress and gave one of them to Arabella, who simpered even more at his “gallantry”, as she’d have described it. Dave leant over and whispered something in her ear, and Kevin spotted her glancing over in his direction while she sipped from her glass. Was that a slight blush on her cheek, or just the effect of the wine? He wasn’t sure, but he did know that embarrassment wasn’t really in Arabella’s repertoire.

Kevin took another swig from his own wine glass. He decided he might as well get drunk, since they’d be getting a taxi home anyway. Arabella would be pissed too, and he just hoped she wouldn’t throw up all over the taxi’s upholstery, like last time. That had cost him an extra hundred quid on top of the usual fare.

This worrying thought had distracted him for a moment, and when he looked over towards Arabella, she’d disappeared. Dave Costello wasn’t in sight either. Kevin scanned the room, and caught a glimpse of his wife’s back disappearing through the door. And what was more, Dave was there too, his hand firmly placed on her trim bottom.

Kevin sighed. No doubt they’d be finding a quiet spot somewhere for a quick snog, and Dave might even chance a quick grope of Arabella’s tits through her dress. Kevin didn’t suppose she’d object.

He looked round. There wasn’t even a fresh glass of wine (let alone a bottle) when you wanted one. He decided to go for a pee first, and then seek out more alcohol to take his mind off the thought of Dave Costello tweaking his wife’s perky nipples. The bogs downstairs were occupied, so he wandered upstairs to where he had a vague recollection there was another set. Luckily these ones were free, so he stood and emptied his bladder while wondering how long he dared leave it before suggesting to Arabella that it was time to go home.

His mind elsewhere, he took a wrong turn out of the toilet and found himself in a part of the building he didn’t recognise. Turning round to retrace his steps, he was suddenly distracted by a giggle, and a muffled exclamation that sounded like, “No, I can’t.”

It seemed to be coming from one of the adjacent offices. He looked up to try and identify the precise source, and noticed that the door to one of the rooms wasn’t quite shut. His curiosity got the better of him, and he quietly positioned himself by the door and put his eye to the gap.

His heart missed a beat as he saw Arabella and Dave Costello leaning against a large desk. Dave’s trousers were down round his knees, and his erect penis was sticking out of the front of his boxer shorts. Arabella was holding it in her hand, stroking it gently, and Kevin was horrified to see that her dress had been pulled right down and Dave was kneading one of her bare breasts.

“Suck it, babe,” muttered Dave Costello, and Arabella looked at him with a filthy grin. Without a word, she knelt down and pulled on his foreskin, revealing his shiny knob-end, then stuck out her tongue and licked gently round the tip.

“Oh fuck,” gasped Dave, his penis twitching at the sensation. Kevin knew what he was feeling. It was a long time since Arabella had fellated him, but she was a real pro, seeming to know exactly when to lick, when to suck gently, and when to go at it 100%, like a Dyson turned up to 11.

She also knew how to deep-throat, and Kevin watched as the whole length of Dave’s erection (a good seven-inches worth) disappeared slowly down her throat, before emerging a few moments later coated in Arabella’s saliva. Dave had begun to play with her breasts again, and Kevin could see how hard and aroused her nipples were.

Some husbands, on catching their wife in the act of giving head to another man, would have burst in and beaten one or both of the guilty parties over the head with a convenient item of office furniture, like a telephone or a chair. But something stopped Kevin. This was partly because he knew that in any encounter of that sort he would be bound to come off worst, but also because (to his surprise) he was beginning to feel more than a little aroused. He could feel his own penis stirring into life in his trousers, blood surging into it as he watched his wife’s lips wrapped around another man’s erection.

Glancing quickly around to make sure he wasn’t being watched himself, he slid down his zipper, put his hand in, and eased out his tumescent organ. It was surprisingly hot, and in a few seconds it had swelled to a hardness he hadn’t experienced for a long time. Cradling it in his hand, he noticed that the shiny helmet was already sticky with secretions of pre-cum liquid. It throbbed excitedly as he squeezed it, rubbing his thumb against the sensitive edge of the helmet.

Looking back through the door, he was just in time to see Arabella withdraw Dave Costello’s penis from her mouth. Her bright red lipstick was smeared over the sides of her mouth, and some of it had rubbed off onto Dave’s shaft.

“Fuck me,” she said; and it wasn’t an expression of surprise. It was an order. Just two words that made Kevin’s heart stop and his penis tingle. He wouldn’t, would he?

Dave Costello didn’t pause to ask stupid questions. He just grunted and turned Arabella round, roughly bending her over the desk so her big breasts dangled and her bum stuck up in the air. He pushed her dress up around her waist, exposing her knicker-less bottom, and eased her cheeks apart with one hand while grasping his erect penis in the other.

Kevin just caught a glimpse of the pink folds of his wife’s vulva, looking very wet and aroused, as Dave positioned his penis at the entrance. Kevin’s own cock was almost painfully erect, and he rubbed it slowly as he watched Dave Costello’s hard-on disappear into his wife’s vagina. Judging that no-one in the room was likely to be looking in his direction, he eased the door open a little, giving himself a better view.

He watched as Dave Costello put his hands on Arabella’s hips and began to pump his cock in and out of her hole. Kevin could hear the schlup, schlup, schlup of her copious juices, and she began to let out a sequence of squeaks and gasps as she sprawled over the desk.

“Oh Dave, yes Dave,” she squealed, “Oh fuck yes, oh fuck, that’s it.”

Kevin began to masturbate in earnest. Suddenly he had an idea, and pulled out his phone. Activating the movie camera app, he aimed it through the gap in the door with one hand while continuing to pump his penis with the other. He had a feeling he’d enjoy watching it back, and masturbating all over again.

Dave Costello didn’t actually last very long before he began to speed up.

“I’m gonna come, babe,” he announced, his pale buttocks tensing up.

“Oh shit, pull out, don’t come in me!” squealed Arabella, and Kevin watched as Dave withdrew his penis with a final schlup and launched several large ropes of semen all over her back. At the same moment, Kevin gave his own cock a final rub and ejaculated all over the door, even more copiously than Dave. He looked at the thick gloops of creamy semen as they began to ooze slowly down the paintwork. He paused the camera app on his phone, then quickly found his handkerchief and wiped the door clean as best he could.
