What's wrong with me?

When they got home they were both drunk and tired when they got home so nothing else happened. The next morning Tom was agitated. Sarah was in a good mood and was swanning around the house getting stuff done and all Tom could think about was how she had been behaving with that Jim guy and how horny it was making him. He secluded himself in his office and tried not to think about it but he would be doing something mundane and an image of Jim's hand stroking her back would come into his mind or the look on Sarah's face as she laughed at one of his jokes. What would have happened if they hadn't been interrupted? he thought and was unnerved by the rush of arousal. What did I want to happen?

He couldn't take it any more and he whipped his cock out at his desk and started to masturbate furiously his mind filled with images of his wife and Jim, mostly just images from the previous night but then his imagination kicked in. She was pushing up against him, her breasts against his chest. He takes her chin with his hand and draws her face closer to his. They kiss, tentatively at first but within seconds it becomes a passionate tongue entwining make out, his hand slides down her body to grab her behind and pulls her against him. She can feel his hard cock pressing against her and her pussy twitches with desire... Tom came in a tissue. He cleaned himself up and tucked his cock back in his trousers. He leaned back in his chair, closed his eyes and rubbed the space in between his eyes. Jesus, what's wrong with me? I guess it was all just a bit unusual last night, it's messing with my head. He got back to work and managed to push through to lunch with a clear head.

He was about to make lunch he called to Sarah to see if she wanted anything but she didn't respond. He walk towards the bedroom and he could hear a noise. He opened the door and he saw Sarah spread out naked on the bed, one hand tweaking her nipple and the other holding their plug in vibrator, eyes closed. He backed out of the room and closed the door slightly and peeked through. She wasn't saying anything just breathing hard, the odd noise squeaking from her mouth as the intense pleasure worked through her. Tom watched, he knew he could walk in and jump on her right now and be welcomed with open arms but if felt so naughty to be spying on his wife. He stroked his crotch through his trousers as he saw her crest an orgasm but kept the vibrator in place to get her towards her next one. He had no idea what she was actually thinking but in his mind it was Jim from last night. She was so **** to cum because he turned her on so much. She didn't want sex with Tom because that would distract her from the fantasy of of that fresh faced executive having his way with her in a corner of the garden. She was cursing that old bastard and his trophy wife for getting in her way and forcing her to have sex with Tom instead.

As Sarah came again, so did Tom, wetting his underwear with his cum. He rushed to the bathroom to remove his clothes before it became too obvious. He jumped in the shower to wash off and he heard Sarah outside the bathroom. "I thought you already had a shower today?" she called.

"I spilled my drink down myself" he lied.

"Oh okay, I was going to make an omelet. Do you want one?"

"Sounds great." he replied eager for her to leave him to his was of shame. Twice in one morning, why can't I stop thinking about it? He jumped out, dried and dressed. He tucked his pants in the bottom of the washing hamper and headed down to the kitchen.

Sarah was in her underwear and a vest looking as casually sexy as it was possible to be. He sat at the table and watched her cute bum wiggle as she cooked at the stove. In his mind he had a vision: A man, dark, lean and handsome walks in. She pauses from her cooking t be kissed by him and she playfully has to bat his eager hands away as she is cooking but she clearly wants more of that attention. She is cooking for him. They have been making love all night and after a morning of sleep she is giving them both some energy before they return to the marital bed for more sex while Tom is unaware.

His cock was hard again and his heart was racing. He felt excited but at the same time glum. He was having to face reality. He wanted Sarah to sleep with someone else. He rested his forehead in his hand with his elbow on the table and tried to make sense of his thoughts but the noise of a plate being put down in front of him. "What's the matter? Are you okay?" said his loving wife and her delicate hand stroked his shoulders. God he loved her, how am i going to deal with this?

"I'm fine," he lied "just feeling a bit under the weather."

Sarah looked at him like she didn't believe him but decided not to push it. She sat opposite and began to eat.

Tom watched her and admired beautiful breasts. Someone could be pulling down that top, would they suck on her nipples the way she liked? Oh god I need to do something about this...
