The work place affair started as any other does I suppose. Although maybe it's easier to start an affair at work? When you work with someone you usually spend more time with that person than your spouse so it's easy to fall into a relationship which is more than just work related.
It started innocently enough. Started with some light flirting and comments such as nice shirt or you look good today. This led to some innocent emails and phone calls - just to say hi of course! After a while those comments got a little racier saying things like I like to walk behind you because your ass looks great in those jeans. Eventually they started telling each other about their sexual pasts and he asked her to tell him about the kinkiest thing she'd ever done which she did.
They began to talk about sex more and eventually she sent him an email saying she wanted him to fuck her. He called her right away and told her not to send things like that in an email because it would flag the IT department to monitor their emails. She was afraid she'd crossed the line because he seemed so upset with her.
Later that day though he called her and told her to find some excuse to come out to see him. She grabbed a note pad and made up some lame excuse for needing to head out then walked out to his office. When she walked in his office he told her to close the door and lock it. She did and he got up, came around his desk, grabbed her face and kissed her hard. He opened his mouth and shoved his tongue deep into her mouth. She kissed him back, pushing her tongue into his mouth as much as she was able. They kissed for a few minutes then he told her she should hustle back to her desk before anyone got suspicious.
This happened a few time and he had occasionally groped her tits through her shirt, then one day he asked her out to his office and he upped the game a little bit. She went out and as usual closed and locked the door. This time as his tongue was deep in her mouth his hand went up the front of her shirt as he started to fondle her tits. When she moaned her approval he lifted her shirt and pulled her tits out of her bra and started sucking hard on her nipples. She was surprised but also very turned on. She was so turned on she didn't object when he slid his hands down her pants and slid his fingers into her pussy and started to finger fuck her there in his office. He had to stop before she could cum though as someone knocked on his door and she had to put herself back together really quick.
Right after that encounter she went on vacation. One day on her vacation she snuck away from her husband and called him. She was on the phone with him for half an hour while they talked dirty to each other. He had her so worked up she fingered herself to an orgasm for him on the phone. Before they hung up he told her they would have to get together when she got back to the office the following week.
