It was a busy week at work. We were working against a deadline and we had to put in long hours to meet them- often very late into the night. To set a little bit of context- we worked with data. We had to train and deploy statistical models that would crunch numbers to make sense of it- it involved a lot of thinking, trial and error. Being a small company, there were just two folks to handle all of this- me and my colleague- let's call her Tanya. Tanya got married a couple of years ago and was technically above me in seniority.

It was Monday night, and the clock struck 8 pm. I had just hit complete on my last task and I packed up to go, when I saw Tanya still intently looking at her screen, typing intermittently.

"Okay, I am done." I announced.

"Oh, you're done, great- why don't you take up some of these tasks and we can both finish early?" she said.

My heart sank a little. "No way- I am done with my tasks, and I have a date which I am really looking forward to." I said.

"Can you please stay back? I have way too many tasks assigned- at this rate I will be here till morning." she said.

She could see that my face had dropped. Looking to cheer me up, she continued. "And if you're looking forward to your date, here's a reward for you- you help me out, and I will flash you my tits.", she chuckled.

The years of HR seminars froze my mind as I tried to come up with my response. "What? Please tell me you're joking." I said.

She was wearing a blouse and a pencil skirt. She removed the first few buttons of her shirt and flashed her bra underneath. She then ran her fingers under the bra to just slightly let her nipples peek out. I could see her dark pink nipples and her huge tits under her bra, and soon- it was my dick guiding my words.

"Okay, fine- I will help you out." I said. I grabbed a chair and sat next to her to take up some of the tasks that she had. She kept her shirt unbuttoned and her bra still slightly down so that you could peek at her nipples. I kept staring at her through the corner of my eye, and she could tell. "If you want to get a better view, you better hurry", she smirked.

Eventually in another two hours, even my added tasks were done. I was curious whether she would hold up her side of the bargain. But as I showed her my work, without even a word, she unhooked her bra and lifted it up and showed me her tits through her unbuttoned shirt. Her tits were gorgeous- round and perfect. Her dark pink nipples poked out. She shook herself and her tits jiggled as I stared at them with unblinking eyes.

She let out a chuckle and then said, "Hey, I am almost done. Do you want to hang back for half an hour? we could leave together." she said.

"Erm, no- I think I will leave", I told her, trying hard not to touch my dick which was becoming increasingly hard.

"Okay, as you wish.", she said, and she casually took off her shirt and bra, and threw them on the floor. With her tits in full display, she sat back down and started working.

I stared hard at her perfect body with her perky tits out, wobbling just a little as she typed. I stared for almost a full minute before she said, "You might want to sit down."

I grabbed a chair and like an absolute pervert, started at her as she nonchalantly kept working with her tits out. With a final few clicks, she said. "okay- now we just have to wait for the data model to train." she said, as she relaxed her head back, bending back on her office chair, arching her back to let her tits pop out even more.

It was a little too much to resist and I ran my hands up her waist and cupped her tits. She smiled and leaned back and bit on her lower lip. I cupped both her tits with my hands and played on her nipples. She moved her hands to my crotch, feeling my hard dick over my pants. She began to rub on it, as I continued to play with her tits.

Her phone rang, and I could see on the screen it was her husband. I immediately stopped touching her, but she kept rubbing on my dick, and in the most casual way- picked up the phone. "Yes honey." she said, as she unbuttoned my pants with one hand and pulled down my zip. She then reached inside and started to feel my dick. My dick felt amazing in her soft hands, and the fact that she was on the phone with her husband somehow made the moment unreal.

"Yea, I am almost done with my work." she said. I pulled down my underwear and she jerked my dick, while I started to pinch and tease her nipples again.

"Yes- I will pick up some takeout on the way from dinner." she said, trying desperately to hold her moan. "Yes, some eggs also from breakfast." she said "mmm. Yes, see you soon babe." She said, as she put down the phone. There was an evil glint in her eyes.

She then went down to her knees, and started to jerk my dick off. She suggestively moved her mouth near my dick, but didn't put it in her mouth. She massaged my balls, and rubbed the tip of my dick on her nipples. All of this was far too much for me to handle, and I somehow kept control. Finally, she brought her tongue to just tease the tip of my dick while jerking me off, and I felt a huge load of cum incoming.

She quickly grabbed my underwear and pulled it over my dick, and I let out ropes and ropes of cum into my underwear. She took her hand out and it was covered with cum, and she licked her hands like a cat. I stared at her in awe, breathing heavily at what just happened.

She put on her clothes and straightened her hair, and looked back at her screen. "Well, there's a lot of work still left in this project now, isn't there?" she winked as I saw her walk out of the office.
