Yes, Sir

Chapter 2: After Class

When the teacher dismissed the rest of the class, I looked on in anguish at everyone else leaving. I waited anxiously for Jordan to acknowledge me again, just to see what was in store for me. I watched as he cleared his whiteboard of pen, staring at his ass through the jeans, until he turned around, flashing a frown at me.
Sir walked over to the door, closing it, and turning the latch. Oh shit, that was ominous. He came and stood over me, like he was before, and it took all of my will power not to stare at his crotch, which was at eye-level.
"So," he began. "Is this what I can expect from you this year?"
I looked up into his eyes. Oh God, his eyes. The blue in them was piercing, and I felt myself getting goosebumps just looking at them. "N-no Sir." I hesitantly answered.
"Being late to your first lesson, not paying attention to your teacher, do you agree that this is worthy of a punishment?"
No. I didn't. Nor did I want to be punished. Being kept back was always awful. But I couldn't say that.
"Yes Sir," I responded despondently.
"I agree. I imagine you got punished quite a few times last year? What did they entail?"
"Uhh, I had to stay behind after class mainly." I replied, with hints of discomfort in my voice. "Sometimes I had my phone confiscated." Sir chuckled.
"Well that did a fat lot of good, didn't it boy?" I didn't answer. "I know what you need, follow me."
I got up out of my seat, following Sir to his desk. I was mesmerised by his jiggling ass as he walked, allowing myself to get caught up in a fantasy for a moment. He sat down and pulled out his chair, leaving me stood in front of him.
"Two options." he began. "First one is, I boot you off the course right now. I can't eb dealing with disobedient little shits every day."
"Sir, you can't do tha-"
"Well that leaves option 2." I saw Sir smirk as he patted his lap, seemingly lookingly me up and down. I gazed at his beautiful face, and began to feel my dick stiffen in my pants. Not a good time.
"A spanking. 10 slaps to your ass. It's the only way people like you can learn, a bit of proper obedience training."
My jaw almost hit the floor in shock. Did he really just say that?
"Sir, you can't do that." I say sheepishly, in a form of protest.
"I know I can't." Was his snappy reply. "Unless you allow it. And if you don't, kiss History goodbye."
I realised I was just about out of options. I walked over to him, awaiting further instruction.
"Unzip your pants and lie over my lap," he said sternly. My shaking hands pulled down my zip as I lay across his muscular thighs. I felt his hand grab my jeans at the waist and pull, and as he did the boxers went with them. He pulled just far enough so all of my ass was exposed, as I lay, red as beetroot from embarrassment, awaiting my punishment.
My dick had fully came out of my jeans, but was still in my boxers, rock hard, rubbing on Sir's leg. I blushed even more, knowing that there was no way he couldn't have noticed this.

*SLAP*

A hard slap came down onto my ass, shocking me and almost causing me to fall off of Sir's lap. I don't know whether it was the shock or the pain itself, but I felt myself welling up.

*SLAP, SLAP, SLAP*

Another three came raining down in quick succession, all on the same cheek. I tried to yelp in pain, but the noise that came out sounded more like a moan. A pleasurable moan. I was fucking enjoying this. My cock was still rock hard, resting uncomfortably between me and Sir's leg.

*SLAP, SLAP, SLAP*

Three more connected with my ass, which by this point must have been red raw. I told myself the worst of it was over, until I suddenly felt something big, rubbing against my hip. My eyes widened as I realised what that must have been. Some first day this has turned out to be.
The last of the slaps connected with my ass, but I waited to be told to get up. I felt Sir's hand rub across my cheeks, and a couple of fingers slyly brush over my asshole. Then, he pulled me up.
I went to pull my jeans up but he stopped me sternly. "Not yet," he said, "The spanking was only part one of your punishment, because that wasn't really a punishment to you at all, was it?" He looked at the bulge in my boxers, and the rather hefty pre-cum stain I'd made. I once again turned a deep shade of red, and tried to look anywhere but into Sir's eyes. I twigged him smiling out the corner of my eye. My raging hard-on was not leaving, as I stood with my jeans down, and my boxers only covering the front.
"I want an assignment on why you have an erection right now, for tomorrow's lesson. Now get lost." I pulled my jeans up and scurried out of the room.
I ran straight to the toilets, knowing everyone else had left. I burst through a cubicle door and jerked my boner furiously, running my other hand across the red cheek I now had. It didn't take long before streams of cum shot all over the toilet, and my hand. I gathered the gathered the cum off my dick onto my fingers, and slowly, licked them clean. I savoured my cum in my mouth, something I'd never done before. What was going on?
