I had called Frank, asking if he had a meeting after his classes were over today. He said he didn't and I asked if I could wait in his office for him to finish and he agreed. I had bought a very special outfit that I'm sure Frank would like very much. I had it covered up by a large coat as I walked into the university.

I went to his office, knowing his classes should end in about ten minutes. I took off the coat and looked in the mirror he had hanging on his wall. I wore an unbuttoned white button up that I had tied just above my belly button with a black tie and a short grey plaid skirt that hardly covered my ass along with some white thigh highs.

I set my coat onto the couch he had in there and sat on his desk, waiting for him to arrive. I heard footsteps as I smirked and leaned back slightly. The door opened and I was happy to see Frank, but was then horrified when I saw he wasn't alone. Frank cursed and the other man blushed then walked out of the room. I jumped off the desk, pulling my coat on and burying my face in my hands in embarrassment.

"I'm sorry," I apologized, feeling tears forming in my eyes from the humiliation.

"Hey, baby, it's okay," Frank said soothingly and rested a hand on my shoulder. "That's just my friend, Brendon, he won't tell anyone."

"Did I embarrass you?" I asked.

"No, of course not," he denied. "I wish I could show you off to everyone so everyone would know how perfect my baby boy is."

I couldn't help but blush and give a small smile as I looked up at him.

"See, there he is, as beautiful as ever," Frank praised, kissing my forehead. "Now, why don't you show daddy your pretty little outfit?"

I nodded and he slowly slipped the coat off my shoulders, letting it fall on the floor with a soft thud. Frank looked over me, biting his lip.

"You buy this just for daddy?" Frank asked and I nodded. "Oh, baby boy, you treat your daddy so well, I think I should treat you well too, huh? Make you feel good?"

I felt my breath hitch as I nodded.

"Although," Frank continued, snapping the thigh high against my chubby skin, "You've been such a bad student, haven't you?"

I felt my whole mouth go dry as I nodded quickly.

"Hm, such a naughty student," Frank muttered, reaching around to squeeze my ass. "Naughty students get punished, ain't that right?"

"Yes, daddy," I answered.

"Sir," Frank corrected, giving my butt a smack.

"Sir," I breathed out. "Y-yes, sir."

"Bend over the desk," he ordered.

I did so immediately, hearing Frank go over to lock the door. A hand ran over my ass, lifting my skirt up.

"Well, you won't be needing these," Frank remarked, pulling my panties down so they fell around my ankles.

Frank grabbed my hair, lifting my head up from where it was resting on the desk.

"Been such a bad student, huh?" Frank asked.

"Yes, sir," I answered.

I saw him smirk as he dropped my head and picked up a ruler.

"I want you to thank me after every spank, got it?" Frank asked.

"Yes, sir," I said, my voice on edge from the excitement.

Frank and I had never done something like this before I was so excited yet anxious.

"Goody boy," Frank muttered.

I felt the wooden stick run across my bare ass, making my heart nearly stop. It was gone for a second but then came across my ass harshly. I yelped, rising up on my toes, which ended up just sticking my ass higher in the air.

"Th-thank you, sir," I stuttered.

The sharp hit me again before I barely even had a chance to finish my sentence. I repeated my words and just as he spanked me the third time, his phone started to ring. He cursed, answering it and putting it up to his ear.

"Hey, baby," he said to who I knew was Jamia.

I frowned, knowing the moment would be ruined but it was picked right back up when Frank pushed two spit covered fingers in my ass, his left hand still holding the phone to his ear. I covered my mouth in an attempt to muffle my moans as he moved his fingers in and out quickly.

"Yeah, sorry, I'm held up at work," Frank apologized over the phone. "There's a student that's been disrupting my class and I've gotta handle him...yeah, I'm gonna get him all sorted out, put him in his place."

His fingers brushed my prostate as he started immediately hitting that spot over and over.

"I'll see you when I get home," Frank said. "Love you, Princess."

I heard him hang up and his fingers moved even faster, finger-fucking me to no end. I could feel my heart pounding, my stomach twisting and turning.

"G-gonna come, daddy," I choked out. "I-I mean Frank, I mean--fuck."

I couldn't even form a coherent sentence from how fucking good it felt to be used so roughly. I heard Frank chuckle darkly behind me.

"Been such a bad student, haven't you?" Frank asked and I nodded quickly. "Been disrupting my class?"

I nodded once again, my nails digging into the wooden desk.

"I know how to shut you up," Frank muttered, still hitting my prostate roughly, slipping in a third finger.

I gasped, pushing back against his hand.

"'M gonna come, sir," I whined.

"Don't you dare even fucking think about it," Frank denied.

I cried out, trying my best not to come. It was rather hard not to when Frank was making me feel so good. He pulled his fingers away and I sighed in relief, but then felt a sharp smack of the ruler on my ass. Frank hit me again and I moaned.

"What do you fucking say?" Frank growled.

"Thank you, sir," I cried, tears falling down my cheeks.

There was a slim layer of sweat on my body, my legs shaking slightly. I felt tapping with the ruler on my inner thighs and I knew to spread my legs a little wider. There was a sharp snap against my ass and my hips jerked.

"Th-thank you, sir," I said.

I could feel the hot, stinging skin as Frank ground his hard on against and my ass. The smooth material of his slacks were cool against my ass. I heard the small clinking as he undid his belt and his pants dropped down around his ankles. I heard him spit and I could feel my heart racing a mile a minute. I felt the head of his erection pressing against me and I could feel the anticipation making me shake. He slammed into me suddenly and I let out a soft scream.

Frank gripped my hips as he started pounding into me. My hips jerked against the hard desk while he fucked into me ruthlessly. I grabbed at the desk, moaning loudly. I felt him grab my tie, spinning it so it was backwards around my neck as he tugged on it. My head lifted up slightly, my eyes rolling back from the lack of oxygen that made everything seem a million times better.

"O-oh fuck, sir," I choked out. "H-harder, please."

I felt him hit my prostate and I cried out, pushing back against him. His hand reached around, jerking me off as I pushed me closer and closer to the edge. I knew if I didn't come soon then I would explode, quite literally, actually.

"P-please, sir, let me come," I cried.

"Mm, but bad students don't get to come," Frank said.

"I'll be good, sir," I promised.

His hand moved faster and I sobbed, my body shaking as I tried my hardest not to come. My insides seemed to be burning, blood thrumming and stomach twisting. My toes curled, hands shaking with my legs. All I could hear was my own heartbeat, ragged breath, and the sound of skin on skin.

"Gonna be a good student, huh?" Frank asked and I nodded as best as I could. "Then come for me, show me how good you can be."

I sobbed as I came in his hand, trying to catch my breath in what seemed to be an airless room. I felt his hips stutter in pattern, thrusting erratically into me. I heard him curse as he came inside me, gripping tighter onto my tie and cutting off all circulation. He rode out his orgasm in shallow thrusts before pulling out, letting go of my tie. My head fell against the desk heavily but I hardly even noticed. I slipped down, sitting on the ground with my back against the desk while Frank pulled up his pants and wiped his hand off with a Kleenex.

"Aren't you just daddy's good little boy?" Frank remarked, kneeling in front of me and running a hand through my hair.

I gave him a tired smile and nodded my head.

"That's right, daddy's perfect baby boy," Frank praised, showering me in kisses.

I giggled happily and he helped me to my feet.

"Here, I think I have something for you in my bag," Frank remembered.

He reached in, grabbing out a bottle of lotion. I smiled, feeling the stinging of my ass as I bent over yet again. The lotion definitely helped as he rubbed it in, soothing the welting skin.

"Good boy," Frank muttered.

I stood up, giving him a kiss and giggling. He grabbed my panties, pulling them up for me and petting my hair.

"C'mon, let me take you home," he offered.

I smiled and nodded my head. I slipped my coat back on, buttoning it up so nobody could see my outfit. We walked through the halls of the university together and out to his car.

"Are you sure it's okay that your friend caught us?" I asked nervously.

"It's perfectly okay, Gee," he reassured me. "I'll talk to him and it'll be alright. Brendon's a pretty cool guy, he wouldn't tell anyone."

I nodded my head, still worried Brendon might tell someone.
