Mr. Jackson, your old Chemistry teacher. He's pretty strict, but you think he'll be nice enough in front of the rest of the town.

You point at Mr. Jackson, who is sitting in the front row. Only a few months ago you were in his Chemistry class, trying to understand all the different chemical reactions he was explaining. Mr. Jackson's pretty strict, one of the few Alphas in the local high school, but with the rowdy teenagers, an Alpha was necessary sometimes.

You were always a little scared of the taller, imposing man, with his bushy black beard and horn-rimmed glasses. You're also not sure why you chose him. Because he's familiar? Because you think he'll be gentle with you, so as not to ruin his reputation as a teacher?

"Hands and knees," Mr. Jackson barks at you, and you tremble as you take your position on the bed. "No, ass to the audience!" The tall man grabs your hips and moves you so your ass is facing the audience. He gives your ass a loud, painful slap, then starts to remove his clothes.

From the corner of your eye, you watch him. You can't believe he just pulled you around like that, then spanked you in front of everyone. So much for hoping that he'd be nice!

Your lust grows as your former teacher gets naked, though. He's nicely muscled, with dark chesthair sprinkled across his broad chest, and his cock is already hard and very impressive. You feel your asshole twitch with the need to be filled by that magnificent cock, and you feel a warm trail of slick run down the back of your thigh.

Mr. Jackson, fully nude, approaches the bed and grins as he runs a finger down the back of your thigh, following the trail of slick. "Someone's an eager little Omega tonight, aren't you?"

When you don't reply, he spanks your ass hard. "Answer the question, boy!"

"Yes!" You manage, your arms trembling now. "Yes, I'm eager!" Part of you wonders if you can send him back. You don't want to be spanked! It hurts too much, especially the way Mr. Jackson does it, with his big, strong hands.

The mattress dips as Mr. Jackson kneels by your side. One of his large hands is resting between your shoulderblades, the other is on your lower back, just above your ass. "Can you name any of the chemicals you're producing right now, boy?"

A Chemistry quiz? Now?! Part of you admires the fact that he can still think clearly with his raging erection. "No, sir," you whimper, and then feel another hard slap on your ass. That one stung!

Mr. Jackson tuts. "Not even a single one, boy?" He spanks you again, and you cry out. "I thought I had taught you better than that."

You gasp as he spanks you again and again, and you hang your head. At least you won't have to look at the crowd, at all those people who are watching you get a spanking from your old teacher. Your ass must be pretty red by now. It's definitely getting sore, and Mr. Jackson spanks you again. You shudder in pain as your ass feels hot now, the warmth from the spanking spreading.

Mr. Jackson grabs your right thigh, and pulls it closer to him, forcing you to spread your legs wider and displaying you to the audience. "Well, that's too bad, because your slick is very interesting, boy."

You moan as he runs a finger across your hole, spreading some of your slick around. "Please, sir!" You push your ass back, wanting more.

Mr. Jackson laughs. "Mmm, you wanna get fucked, boy?"

You nod, and get spanked again. "Yes, sir!" you yelp. Oh, it's starting to feel good now. The pain from the spanking, your ass feeling hot, combined with your heat are making you even hornier. Your ass is so sensitive and your body so eager, that it's taking any stimulation as good. Your cock is leaking pre-cum on the sheets underneath you.

Mr. Jackson spanks you again, and this time you moan in pleasure. He spanks you a second time, and when you moan, he rests his hand on your ass. "You're enjoying this, boy?"

"Uh huh, yes, sir," you reply, rubbing your aching ass against his large hand. Mmm, the palm of his hand feels so good and rough against your sore ass.

"Wonderful," Mr. Jackson grunts, and you feel him move behind you. "You're ready to get fucked, then."

You want to argue that you've been ready to get fucked for a while now, but he shoves his massive cock in your tiny, slicked up hole in one hard move, and you cry out in pain and pleasure as he goes balls-deep. "Yes, fuck me, sir! Oooh yes!"

"You like that, boy? Like being filled with Alpha cock?"

"Yes sir," you manage, collapsing onto your elbows. Your ass sticks in the air even more, and being fucked like this feels even better. "Oooh, fill me up, sir, fill my asshole."

Mr. Jackson's thrusts are relentless, pistoning in and out of your asshole. Your entire ass still aches from the spanking, but that only adds to the pleasure of being fucked and filled. "You gonna be good obedient Omega, boy?"

"Yes, sir," you moan. Oh God, you can feel your orgasm building faster and faster.

"You gonna listen to your Alphas, boy? Do exactly as they say?"

"Uh huh," you mumble. You'll do anything so long as it means getting filled with big, hard cocks like this. "Yes, sir."

"You gonna not come until your Alpha does?"

You gasp at that. "Wh-what?"

"You heard me." He manages to spank you while fucking you. "I wanna come and fill that pretty Omega ass of yours before you get to come. Understood, boy?"

"Y-yes, sir!" You immediately start thinking of the least sexy things you can think of, remembering both maths equations and molecules and atoms and Mr. Jackson leaning over you at your desk. No, no, don't think about that!

Mr. Jackson keeps fucking you hard and deep, his balls slapping against your ass with each thrust. "I hope you're not close yet, boy."

You moan desperately. "Please, sir, I wanna come! Fuck me harder, if that's what you need!"

Mr. Jackson's hold on your hips tightens, and he pulls you back each time he thrusts in, forcing his massive cock even deeper inside of you. "Mmm, you're exactly what I need, a good little Omega to bury my dick in."

"Yesss, sir," you enthusiastically agree. Mr. Jackson can bury his dick inside of you any time. You try to do calculations in your head, or list all states of the US, anything to keep your mind away from the big cock rubbing inside of you and making you feel so good. You feel like you're bursting with the need to come. "Mmm, fuck me!"

Finally, Mr. Jackson thrusts in deep and his cock twitches when he comes. His fingers dig into your hips, almost painfully so, and he fills you up with his come.

It feels like it'll never end, and with a shudder, he pulls out. Then, he gives you one last spank, and it pushes you over the edges. You gasp and whimper as you come, spilling onto the sheets underneath you. Oh God, everyone saw you coming just from being spanked like that!
