It started as any other day, warm up, treating patients, and talking to the other girls at work. Then I get a text from our boss, it simply reads “come to my office”.

I excuse myself, making up some excuse and hurry to him. Grinning, because I had been waiting for this text all morning… I knew this was pertaining to the bikini bottoms I soaked when I fingered myself in his truck. He had let me borrow it while he was on vacation with his wife.

I walk in and say, “you wanted to see me?” “Shut the door and lock it” he commands as he’s sitting at his desk. “Yes, master”, I answer with a mischievous look in my eyes.

Glaring at me and holding up the bikini bottoms in question and states, “you’ve been a very naughty girl. You left these in my truck.”

Eyes downcast, I whisper, “I thought you’d want to know how much I enjoyed you letting me use your truck…”

He growls, “I know very well what you wanted…. You wanted her to find them so, she would know that I spoil you.”

Not being able to hold back, I giggle. Seething he says, “come here, pull down your pants and panties, and put your hands on the desk.” I smile, slowly walking over. Facing his desk, I take off my jacket. Pull down my scrubs and panties to my ankles. Bend over his desk with my feet apart, forearms down and palms spread on the table.

He whispers in my ear, “do not make a sound.” I feel him trace a finger down my spine, my ass, and between my thighs, noticing how wet I already am. “You should not enjoy upsetting me.” I try not to squirm with anticipation of the punishment I know is coming.

He does not hold back as he spanks me once, hard. I bite my lip as I try to remain quiet. “You need to be properly trained so, you will not do this again.”

I brace myself for another hard crack of his open hand on my ass. My face flushes at how loudly it echoes in his office. I know there’s no way the rest of the clinic cannot hear me being punished. No one will dare interrupt him and risk gaining his attention instead.

His spankings progressively get harder and faster, switching between cheeks. Trying to contain my whimpers, I bite my lip so hard I taste blood. He stops and asks “Will you displease me again?” I quickly shake my head, not daring to disobey his order of silence.

“Good girl.” He purrs. I can feel the heat radiating from ass and I know I will have bruises tomorrow. Watching my juices drip down my legs, he unzips his pants and pulls out his already hard cock.

He grabs a fistful of my hair and growls, “Don’t you dare cum while I fuck you. You are to be used for my pleasure only, today. You’ve been such a dirty slut while I’ve been gone.” Another hard spank right before he slams himself deep inside of me. I gasp and he shoves my bikini bottoms in my mouth. He punctuates each thrust with a word, “I. Told. You. To. Be. Quiet.”

Shoving me against the hard desk, he slams into me, hard and fast, over and over again. I have to dig my nails into my palms to obey him. Allowing the pain to keep me from tipping over the edge and cumming.

I start to feel him shake as he gets close. He quickly pulls out and spills his seed onto my back. I look back at him, in shock of his cum all over my scrub top.

He grabs my hair, pulls me around to face him and says, “you will NOT clean that up. You will wear the mess I made on you the rest of the day to remind you how you not to displease me again.”

Whimpering I sigh, “yes, master”. “Good girl” he smiles, as he kisses me briefly and tells me to leave.

I pull up my panties, instantly soaking them and blush. Then, I pull up my pants hoping that I do not leak through them, and betray to the others, how much I enjoyed his punishment. Flushed and trying to compose myself, I put on my jacket to hide the mess he made on me and go back to work.
