"Sir, I've got the reports you wanted on this quarter"
"Hurry up and bring them over then. Any anomalies I should be aware of before I start skimming?"
"A couple at least. For one..."
The rest of the conversation was lost to me. It wouldn't be the first conversation I technically overheard that maybe I shouldn't. But I rarely registered any of it in my position. Well out of sight, struggling to keep still, his foot pushed into my crotch and rubbing softly as he spoke. My mouth held open with a ring gag, his member pushed in and teasing my throat. Senses partially stripped by a blindfold, his touch and taste amplified. Ropes holding my body still, barring me from pulling back much or resisting his usage of me...
...and I reveled in it.
It was hard breathing with how deeply he had me taking him. My focus locked on that, the subtle drip of his precum slipping down my throat making it all the more difficult. My eyes rolling with every subtle push of his foot, it amazed me how he could just sit there, calmly talking with his secretary as if I didn't exist. So far as anyone else was concerned I might as well not exist at all though. Unseen, unheard... the potentially severe punishment for either being breached ensuring my cooperation in moments like these. And thus, my attentions were consumed by that effort.
An eternity, and finally their conversation was ending. I heard the click of a boot as his secretary turned, felt his hand come down and find my hair as footsteps receded. A quick pull saw my throat forced by his cock, a struggle to not gag as I heard the door opening. It closed with their departure, my hair finally released and a muffled retch coming from me as I pulled back enough to cough and get air. His lustful chuckle sent shivers of desire through me as I leaned into his now caressing hand.
"I have a meeting to tend to shortly, slave. I trust you won't cause any issues..." I moaned muffledly as he thrust into my mouth again before standing. I couldn't see him, but I could hear him sorting himself out and tucking his shirt in. A snap as he straightened his jacket, a final parting nudge from his foot... and out he went. Each parting footstep mentally placing him in the room for me, the door creaking open and shut once more. And I was alone.
I stretched as much as I could, muscles aching from the restraints. Some gentle flexings of my jaw confirmed its inevitable soreness later, but I was used to such. The "arrangement" we had was a long standing one, born of his lustful desires and my longing to be near him more often. It had embarrassed the first couple times, but eventually I got comfortable with my subtle exposure and vulnerability. Anxious worry had evolved to quiet exhilaration every time he had someone in his office, knowing the secret shared between him and I and how easily that secrecy could be ripped away from me-
The door opened. I immediately perked up in surprise, my head lightly bumping the desk. It had only been a couple minutes. His meetings never ran that short and he hadn't forgotten something ever, at least not while I was here. Listening intently to the footsteps, my heart quickly raced... it wasn't him. Every footstep held my attention, my breath bated as I quietly hoped my head bump from earlier wasn't heard...
"... oh, right, he's in a meeting. Eh, might as well leave the memo on his desk". Panic took me, my body frozen as I tried remaining still, quiet. I didn't know who this was, Master wasn't there to distract them... even the smallest noise might be noticed. Surely they'd just quickly drop the memo off and leave though. It'd be fine...right? Over they walked quickly, a faint rustle of paper as a folder was opened and rifled through. Probably one they brought in with them, a quiet "got it" as a certain paper was removed and set onto his desk.
"...Damn, the view in here is something" I could have screamed in anxious frustration as I heard the unknown underling step towards a side of the desk to get a better look out the floor to ceiling windows. It provided a full skyline view of the city, high enough up that I wasn't afraid of being seen by others in other buildings (though such a possibility did have an appeal....) Another step. He was about to move around the side of the desk. I tried to scoot back a bit, hide myself better...
