Diane looked up from her computer screen when the APC started to chirp and noticed that the second hand on the clock wasn't moving. "Not again" she groaned as she shut down her computer. It was the third time in six months that the power had gone down. When was the landlord going to get his head out of his ass and do something about the problem?

She got up from her desk and walked down the hall to Mike's office. He was on his cell phone and she waited for him to disconnect. He finished his call and he looked up at her and answered her unasked question:

"I don't know. He says he called the electrician and the electrician said he couldn't get here for at least an hour. It took them three hours to fix the problem last time so figure three, maybe four hours minimum. Three hours would make it what, two-thirty? You might as well take the rest of the day off."

"Okay. I'll be on my cell if anything changes."

Diane walked back to her office and got her purse. She looked at her watch and saw that it was eleven-forty. That was just enough time for her to get over to the Bachmann Building before Rob went to lunch. She rarely got to have lunch with her husband; their work places were fifteen minutes apart so that amounted to thirty minutes travel time round trip and with only an hour for lunch it wasn't feasible. Today, thanks to a penny-pinching landlord, she would have the time.

She stepped off the elevator on the fifth floor and turned left to go to room 512. As she entered the office she saw all the empty desks and she looked at her watch. Unless it was slow she was there before the noon lunch hour. She saw several balloons pinned to the bulletin board and she walked over and saw the poster that announced the luncheon in the cafeteria to say good-bye to Brenda who was going on maternity leave.

She turned to head for the basement cafeteria and then she checked herself. She would check Rob's office before going down to the basement. Rob wasn't a baby shower, bridal shower, going away party kind of guy. He would give generously for a gift, but he would usually avoid the get togethers. She walked up to his office and was reaching for the doorknob when she heard it. It was a moan, but it was not a moan of pain, a moan from someone hurting or in trouble. She heard it again and she put her ear to the door.

"Harder baby, harder. You have to get me there baby, make me cum."

Diane very carefully and quietly turned the doorknob and opened the door just a crack. "Fuck me baby, fuck me" she heard and she opened the door a little at a time until she could see what was happening in the office. There was a woman laying on her back on Rob's desk and her legs were up on the shoulders of the man who was fucking her. The man's back was to Diane, his trousers in a puddle around his ankles, but even though the man's back was to her she knew the man was Rob. There was no mistaking the birthmark on his right butt cheek. She backed up and pulled the door closed until only a crack remained and then she stood there and listened as her husband pounded into the woman lying on his desk.

"Come on Rob honey, make me cum, hurry baby, hurry."

Diane cringed as she listened to the 'slap, slap, slap' of flesh smacking into flesh.

"Come on baby, come on. Fuck me hard, make me cum baby, make me cum."

"Hurry up sweetie" Rob said, "I'm almost there, hurry, I don't want to leave you hanging. Cum with me sweetie, cum with me."

"Oh, oh, oh, oh, Oh God, oh God yessssss" the woman shouted as she had her orgasm and seconds later, "Let me up Rob, I need to get down to Brenda's luncheon. Tonight? After work?"

"You bet."

"Get a couch in here Rob, will you please. Either that or an air mattress for the floor. This desk is hard on my back."

Rob was saying, "I'll get something" as Diane quietly closed the door and hurried from the office.

Diane wasn't surprised at what she had discovered. She had hoped it would never happen, but deep down inside she had been expecting it. She thought back to the barbecue she and Rob had attended nine years ago. He had been working for McIlhenny's at the time and old man McIlhenny had thrown a huge barbecue and pool party for his customers, suppliers and employees. Diane loved to swim so she had spent a lot of time in and around the pool. Rob, on the other hand, had no use for water except for showering and drinking. He spent most of his time drinking beer and socializing.

Three hours into the party she had gone into the house to use the bathroom. She had just come out of the bathroom when she heard, "Oh Rob honey" and some giggles from a room just across the hall. There may have been some other Rob's at the party, but her curiosity was aroused and she had opened the door to the room and had found her husband with his hand inside the bikini top of a dishwater blond. The dishwater blond had her hand inside Rob's fly.

She was mad, extremely pissed, but she had been raised with manners and a scene in someone else's house was just something she couldn't do. She stepped into the room and said:

"Excuse me for interrupting, but I need the keys to the car."

The blood had gone from Rob's face and he looked pale and ashen as he fumbled in his pockets for the keys, came up with them and handed them to her. Only after she had taken them from him did he recover enough presence of mind to ask her what she needed them for.

"I'm going home."

"Wait up. I'll say my good-byes."

"You aren't coming with me."

"How am I supposed to get home?" he whined.

"I don't care if you ever come home asshole."

She was turning to leave when the blond had asked who she was.

"I'm the wife of this asshole."

"You never told me you were married," the blond was saying to Rob as Diane walked out the door. She was only ten steps down the hallway when she heard a yelp of pain and the blond came running after her.

"I'm sorry, but I didn't know he was married. He wasn't wearing a ring."

"What was that yell about?"

"I kneed him in the balls."

"Good for you."

Rob had come home that night all contrite and begging for forgiveness. He had blamed it on too much to drink and some flirting that had gotten a little out of hand. In the end she had forgiven him, but she had put him on notice that a second mistake would not be tolerated.

When she had delivered that ultimatum her meaning had been clear. Fuck up again and she would throw him out on his ear, but things had changed since then. Then they had lived in an apartment, now they had a house. Then they were childless, now they had two children. Then they were just starting out and money was tight, but now Rob was making six figures. She had gone back to work to have something to do when her kids both started school, but she wasn't the least bit interested in becoming a single mother of two living in an apartment somewhere.

No, divorce was not an option, at least not at that time, but she had to do something. She had to get back at Rob if for no other reason than her own peace of mind. She wondered how many times in the last seven years Rob had cheated on her and then she realized that it didn't matter; the one she knew about was one too many.

Her cell rang and she answered it. It was Mike. The power was back on and he wanted to know if she could come back in.

"I know I told you to take the rest of the day off, but Steven's called and would like our proposal by tomorrow. That's a week ahead of when it was supposed to be due. I hate to ask Di, but I need help."

"Sure Mike, I'll see you in a few."

As she dropped her phone back in her purse she smiled; she knew just what she was going to do to get back at Rob.

She checked her make up one last time. Her panties and her bra were in her purse and the top three buttons on her blouse were undone. She had stopped at a shoe store on the way back to work and had bought a pair of high heels to replace the flats she had worn to work.
