Me: You have to do exactly as I say—got it?

Eva: Got it.

Me: Don’t sound so enthused.

Eva: I just know you’re going to lose, and I already feel bad for you.

I let a laugh slip out as I looked across the hallway and stared at her. She looked over, a smug smile on her face as I raised an eyebrow at her. She had no idea who she was playing with. Game. On.

Me: Take your finger and slowly touch yourself.

I watched as she read the words, her body stiffening in response.

Me: Now, Eva. Slide a finger inside of your pussy.

Her shoulders rose and fell as she let out a long breath before casting a glance at me. Her hand slowly moved under her desk and brushed against her thigh before it hesitated by her pussy. I could see how nervous she was that I was watching her, and it turned me on even more. She closed her eyes and leaned her head back against the leather chair, spreading her legs open even more to slide a finger along her slit. My dick twitched as I watched her body react to the sensation of her touch, knowing that she was fully aroused.

Me: Good, now stick another finger inside.

Her eyes flickered open as she read the message. She didn’t bother looking my way before doing as I asked and slid another finger inside. My eyes were fixated on her hand as she fingered herself under her desk while I watched.

Me: Now, tell me how wet you are.

She kept her fingers inside, working them in and out of her pussy while she reached over and typed with the other hand.

Eva: So wet...

Me: Good. I can’t wait to see your face as you come for me in a few minutes.

Eva: We’ll see.

Me: Take your finger and slide it up to your clit. Rub those juices all over it.

I leaned back in my chair, thankful that my desk was fully covered in the front so no one could see as I unzipped my pants and pulled my dick out. It was hard as a fucking rock, my hand working up and down the shaft as I watched her rub her clit. I continued to stroke myself with my left hand so I could type with my right.

Me: Rub it harder, Eva. Rub it as you think about how hard my dick was as I plowed into you from behind against this window.

My orgasm was close, the pressure building as I watched her and thought back to us fucking in my office. Her eyes were trying to stay open so she could read the messages, but I could tell her orgasm was close as well by how she was straining to focus and pay attention.

Me: Rub it for me and imagine the guy who was jacking off while watching us fuck. I bet he wished he could be in front of you while you took his big dick down your throat and I fucked you from behind.

Her eyes closed after she read the words I had sent, her fingers rubbing her clit quickly while her other hand roamed up her body and caressed her breast. I watched the way her body shifted, and her hips bucked as she lifted off the chair, her orgasm ripping through her while she tried to stifle a moan. Her face looked beautiful, her lips parted, and her mouth opened as she came undone in her office. I closed my eyes as I came under my desk, gripping the edge of it tightly while my other hand finished me off.

Me: Told you.

I leaned back against my chair as my breathing started to even out. I had a mess to clean up, but thankfully, there was a bathroom attached to my office, and no one would notice if I changed pants, given I typically wore black slacks.

Eva: It was worth it...

Me: I’ve never been so jealous of your fingers as I am right now. Lick them and tell me how good you taste.

Eva: Come over here and do it yourself. Unless you’re afraid you won’t be able to control yourself...

Me: I think we both know that the whole office will know that we’re fucking if I come over there and lick your fingers, Eva. There is no control when it comes to you.

I hadn’t meant to say that to her, but when she looked at me with longing on her face, I knew she already knew. We were damned either way.

Eva and I avoided each other for the rest of the day with neither of us bothering to stop and actually eat lunch. By the time I had a few minutes free to eat something, it was already time to head home. I walked out of my office at the same time as Eva and noticed her cheeks flush with color as she lowered her head and tried to avoid looking at me. I struggled to keep the smile off my face but found it nearly impossible as I replayed the images of what had happened earlier.
