The build up

They were like a pair of rabbits for two days straight. Every morning and a couple of times in the evening they had sex. It was Sarah who put a stop to it "Easy tiger. We should hold off now. That way we'll both be nice and worked up by Saturday night. Besides it will be the first cock I've had other than yours in years. I don't want to be too sore to enjoy it." That nearly made Tom rampant but he agreed that they wouldn't have sex until after Saturday. A small part of him quite enjoyed being denied and it took all his willpower to not masturbate constantly.

They had laid down some rules. Tom promised to let her get on with it and not call or text as long as she promised to check in even if only to let him know where she was going to be that night. She agreed that she should use a condom and not do anything she was uncomfortable with. They were going to continue the ruse that Tom didn't know and that this was an affair so they might as well let him think he was seducing Sarah away from him. Tom didn't like the guy very much but the fact that Tom found him a little scummy was playing into his own fantasy so there was no need for them to be friends.

Towards the end of the week a courier arrived with a parcel for Sarah. It was quite clearly the outfit for Saturday night and as Sarah was at work Tom was sorely tempted to look at it. He was proud of himself for resisting though and sure enough as soon as Sarah got home she disappeared into the bedroom to try it on. Tom tried to go in but she had locked the door. "No spoilers allowed" she called from behind the door "You can see it before I go out. Besides I think if you see this now you might get a bit carried away." She wasn't wrong, in fact just the thought of her dressed in a sexy outfit foot the benefit of another man was making it hard not to masturbate outside the door.

Sure enough Saturday arrived. They had both managed to restrain themselves from sex despite some moments that had one or the other of them flushing and breathing hard with desire. Tom had also managed not to cum for a couple of days so he would have something to occupy him this evening. An evening on his own at home while his wife was out having fun and maybe much more. He shuffled to adjust the position of his boner as they ate their breakfast. "What's the plan for after the event?" he said, trying to make it sound like a casual question.

Sarah looked at him, the corners of her mouth pointing up in amusement "He said he's booked a hotel for this evening and that I was welcome to share his suite if I liked. He also added something about a spare bed because he didn't want me to feel pressured. To be honest, if I bail, I'm coming home. If I stay, we won't be in separate beds." She gave him a lingering look through lidded eyes.

Tom gulped before asking "When did you speak to him?"

"Oh, he's been messaging me all week."

"All week? You didn't say anything."

"No I didn't did I" she stated with mock surprise before smiling at him to tell him she was fully aware of how this small secret would effect him.

This small signal instantly made Tom feel better. She wasn't hiding things to keep them from him but keeping them from him because she knows it will mess with his mind in playful ways. His mouth went slightly dry at the revelation none the less and he asked "What did you speak about?"

Sarah shrugged but was holding his gaze like a snake charmer "Mostly the weekend. I thanked him for the lovely dress he told me how beautiful I was and how he couldn't wait to have me on his arm. There may have been a little light flirting. He did ask after you, I told him that you thought I was going to meet up with an old friend for a female focussed charity that was women only. That's why you weren't able to go. He thought that was very inventive and I must admit I was pretty pleased about it. I also told him that you were expecting me to be out all night." She had positively purred those last words and poor Tom was almost ready to spurt.

Saturday turned out to be the longest day Tom could ever remember. His mind was so filled with excitement and trepidation he didn't know what to do with himself. He took some small solace in the fact that Sarah also seemed to be nervous despite her earlier confident teasing.

Eventually Sarah stood up and said "I'm going to get ready."

Tom jumped to his feet too and said "Can I come watch you?"

They were stood right in front of each other and Sarah looked up and bit her lip and shook her head "No baby. My body isn't for you tonight."

Tom sighed "I was hoping to see you that new lingerie."

Sarah looked a little guilty "Actually, you will be waiting a bit longer for that. It doesn't work with he dress I'm wearing and I'm sticking to the rule that I want him to be the first to see me in it, at least for now."

Tom was breathing deeply now as he dealt with the mixture of emotions and arousal that were swimming in him. He stammered "W What are you wearing then?"

Sarah put her hand on his chest "That's a very personal question to ask a lady, but if you must know, it's something Jim bought for me." She reached her face up to Tom's and kissed him on the cheek gave him a naughty look and walked off upstairs.

Tom tried to concentrate on watching something but ended up just flicking through things on his phone. When he heard footsteps on the stairs he leapt up and was stood in the middle of the room expectantly as Sarah walked in. She looked like she belonged in a Bond film. The black cocktail dress went to her ankles and her painted toes were visible through high strappy sandals with a thin stiletto heel. Her left leg was exposed with a slit that ran almost to her hip. The dress had thick enough straps for her to wear a bra and said bra was pressing her breasts together and up giving her a cleavage you could take a nap on. Her arms were covered by long satin gloves that went past her elbow and her face was done up more elaborately than normal but sticking to her style of dark lips and vampy eye makeup. Tom could imagine a small pistol being kept in the clutch bag she was carrying to **** the man she had seduced into privacy.

She did a little twirl "What do you think?"

"You know what I think."

"But I like to hear you say it."

"Beautiful. More beautiful than I deserve."

Sarah frowned and walked up to him. She was almost as tall as him now she had the heels on and she put her face in front of his and said "You do deserve me, don't doubt that." She held her serious look for a second as she looked at him to make sure he understood, then it dropped and she smiled again "That doesn't mean that other men don't deserve me too." She booped him on the nose and turned to walk out.

Tom hadn't noticed the car pull up outside and snapping out of his trance he followed her to the door and watched as she climbed in the limousine that had been sent for her. The driver held the door for her and just before she got in she turned and blew him a kiss. Tom stood and watched as the car drove off down the street and out of sight.
