Even though I am Evan's boss at the office, he is still my dominant and has my full consent to set expectations, challenges, and sessions as he chooses. Naturally, I trust his professionalism completely, even at work. A perfect example would be last week. Evan has sent an expectations for me not to wear underwear without his permission. I agreed to this. Last week, I did not meet this expectation when I forgot to get his permission.

Luckily, it was a quiet day at work, and no one but the two of us were in the office all morning. Evan was in my office notifying me of a change to my calendar when I bent over to pick up a pen I had dropped.

"Are those panty lines I see?" he quietly asked, his voice deep and dommy.

I stood up, spun around, faced him and answered, "Yes. The last time I wore these trousers, you gave me permission, so I assumed. . ."

My voice faded as I saw the look on his face and realized my mistake. Never, ever assume permission. He glanced at his appointment calendar before shutting my office door and locking it.

"Your next appointment isn't for three hours. Take off those trousers immediately, along with the panties. Hand both to me and bend over the desk."

"Yes, Evan."

How he can switch from a complete professional administrative assistant to a stern, no-nonsense dominant in seconds will always be a wonder. Naturally, I obeyed. Nothing else needed to be stated, so I said nothing. He placed a hand on my lower back and began spanking me with his hand for a warm-up. I shifted from foot to foot when it began to sting. This was his signal that I was ready.

He paused, and I heard his belt slide from his trousers. "Not a yelp or word from you, Missy."

I lasted all of three lashes. He said, "Open."

I opened my mouth. He shoved my panties in. "Now bite on that if you need to. You have seven more lashes."

I bit down hard as he continued lashing my ass. Sitting through my meetings this afternoon wasn't going to be easy. Still, I deserved this, wanted it really. I had not met an expectation. I had lied when I told him I has assumed. The truth was, I had simply forgotten about the expectation completely.

If he let me get by with that, I'd push even more expectations until I lost respect for him. Finally, he finished all ten lashes. I wasn't sobbing, but I was breathing hard.

"Well done. I'm not finished, so stay as you are," he warned when I began to turn to thank him.

I heard him open our locked cabinet and groaned. I felt a cold burning sensation as he pressed peppermint lube into my anus and insert a rather large plug. The pressure of it being inserted was uncomfortable, but its width combined with the tingling peppermint oil would be horrendous.

"There. That can stay in for one hour. I know you better than to accept that you assumed I'd agree which means you lied to me. The plug is punishment for that lie. When one hour is up, you will buzz me back into this office and thank me. Agreed?"

"Yes, Evan." I could have said no, but I totally deserved this.

"Good. Now, put your trousers back on and let's get to work."

I was grateful I'd worn black trousers, which would hide any wet spots from the lube as well as my own telltale sign of excitement.

He left to attend to his duties, and I sat, delicately, completing mine. At exactly 11:47, I buzzed Evan and said, "Evan, could you come in here, please?"

By the time he closed and locked the door behind him, I was on my knees in front of my desk. He said nothing, just stood before me. I knew my job, so I unzipped his trousers and unbuckled his belt. I released his flaccid cock and looked up at him.

"Thank you for correcting my mistake and for catching me in a lie. Thank you for not allowing me to get away with anything."

Then I gently kissed each of his balls before cradling them in my hand and kissed my way up his cock. I slid my lips over the crown and slowly pressed my way back down to his base. I sucked and worshiped him until my jaws ached and he lay a soft hand on my head and said, "You're welcome. Back in position, please."

I stood, somewhat disappointed, and took off my pants. I'd been hoping he'd come in my mouth. Now, silently bent over the desk, I wasn't sure what to expect. I was dripping wet when his now-hard cock entered me. I sighed, filled with gratitude as well as pleasure. He pressed one hand down in the center of my back and lightly pinched my clit with the other. I exploded around his cock. He continued to fuck me, granting me several more orgasms. This fucking was not for my pleasure, but for his. He pounded into me with primal force, making sure my body would be soft and replete and filled with him. He fisted my loosened hair in his hand and pulled my head back as he released his own pleasure inside of me.

He leaned down, kissed my neck, and whispered, "Well done." He tapped the end of the plug. I gasped and came again. "Now, go clean up and get dressed."

I stood slowly, a bit dazed. Evan had already straightened himself and looked every inch the professional. I, however, had mussy hair, cum running down my thighs, and a large plug still in my ass. He looked at me, smirked, and said, "You have ten minutes. Then, I'm going to let the delivery guy into this office with your lunch. You better be sitting at your desk by then, or he'll get an eyeful, and I'll have to spank you again."

My eyes widened, and I squeaked as I grabbed my pants and rushed to my private bathroom. I made it back to my desk, my French roll in place, fresh lipstick on, and smiling with a good fifteen seconds to spare when Evan knocked on my door and said, "Lunch!"

After lunch and before my afternoon meetings, he came in again and gave me a briefing of what I needed to know for the clients. When he finished, he asked, "How's that plug?"

"Uncomfortable," I murmured.

"Good," he answered. "You deserve to be uncomfortable. Does it hurt?"

I wiggled on my seat, checking how things were situated before saying, "No. Just uncomfortable."

"You can handle it then. I'm keeping it in until we get home. Then, I'll remove it and fuck that well-stretched ass. Not as punishment this time," he grinned at me, "just because I can't wait to be inside of you again, and this time, your ass is mine."

I giggled, my toes curling in my high heels, then we both put on our game faces.

Let's face it, having your dominant as your personal assistant makes the workday a lot more interesting.
