Tracy cast a smug look my way. Great, just great, my girlfriend was not going to be pleased about this. There was no way I could get out of a late night here. Not now that Tracy had spoken on behalf of us both to the boss.
I sat back down at my desk and glanced at Tracy who just smiled and then got back out of her chair, lifting her skirt as she did to give me another glimpse of her suspenders. I sighed and looked at the phone. I was going to have to make the call and try to explain my working back tonight.
I punched in the numbers of her mobile and waited for her to pick up.

"Hiya babe" I said, trying to think of a way to get myself out of the doghouse I knew I would be in tonight.

"Look, the boss has asked me to work back tonight to try and get this deadline met, yeah, I know but what can I do?" I pleded, knowing full well I had told a white lie about the boss asking me to work back.

Tracy moved over to the person sitting opposite me and leant over, I could see straight down her buttoned-up jacket. She gave me a quick wink and a smile. She only had a bra on underneath. The garment was struggling to keep her huge tits housed. She was deliberately leaning over in front of me so I could look straight down the jacket. My tackle sprang to life again, I didn't know how much more of this I could take.

"Huh, sorry, what did you say I missed that" I stammed into the phone. Tracy giggled and stood upright and moved back to her desk.

"I know, I know but he asked me to work on it tonight. I can't really say no can I?

Another e-mail, oh god, Tracy was becoming more and more overt. The flirting must have been turning her on in a big way. I knew she had been wearing a shirt, she had her jacket off before lunchtime. She had actually gone into the ladies room and taken it off and then come back so she could play with me, allowed me to see those firm breasts. Those large, firm, suckable breasts. I pictured those breasts heaving, boucing wildly as she rode me cowgirl style. My hands feeling her toned thighs and griping her narrow waist, helping her to ride my hard-on. Groaning and moaning ever more loudly as our pace fastened. Her nipples hard and erect as she impaled herself on me time and again. Her head thrashing around, her blonde hair flying in all directions as she lost herself on my cock.

"Yeah, well I'll be late, don't wait up" I was on the couch for sure. The girlfriend was pissed off to the max.

I hung up and thought about Tracy, actually I was thinking more about Tracy's boucing tits.

I opened the e-mail that she'd sent me.
