Detention

-Dungeons, Potions Classroom-

"Ahh~ Oh yes! Deeper Alpha!" Harry begged.

He felt his Alpha's growl reverberate along his back, a hard thrust almost driving him off the desk he was perched on top of. Attached back to chest Severus Snape draped over him, as the older man rammed his girthy length deeper into the Omega's tight crevice, the plump arse rippling with every thrust. Potion-stained fingers played with his pebble nipples making Harry mewl as his Alpha continued to fuck him, filling him up so wonderfully.

"Do you like that Omega? Such a slut for your Alpha's cock, you're taking me so well. Do you want my knot Omega?" Severus spoke as he slowed his thrusts, sliding out slowly and then snapping his hips back in. Harry responded with a whine pushing back against his Alpha trying to get more of his large cock inside of him.

"Yes Alpha~ Need your cock inside me. You fill me up so good. Please! More! Give me your knot. Want you to breed me Alpha. Fill me with your seed. Give me pups Alpha! AHH! Ohh! Ngh!"

Severus growled and the last of his control snapped, he straightened. He placed his right hand on Harry's shoulder and the other on his hips, he began to fuck his Omega harder. Pulling the small body towards him for leverage, as he snapped his hips forward. Watching how his cock disappeared inside his Omega, the bubble arse bouncing with every thrust. Harry moaned loudly in his pleasure a babble of 'breed me, breed me, breed me' leaving his lips, urging his Alpha to mate him, to breed, and to take what was his.

"I am going to fill you up Omega. Breed you full of my seed. Then I will breed you again and continue to pump more into your belly until it takes. I will take pleasure in seeing you round with my pups." Severus growled into Harry's ear making the Omega whine in want.

Harry whimpered and whined as he felt the growing of his Alpha's knot pushing past his rim. 'It's HUGE,' he thought deliriously from the pleasure, 'YES!' A moan/whine escaping him when his Alpha gave one last thrust and forced his knot inside.

The sound of panting filled that room as the two came down from the high of their orgasms. Harry squeaked when he felt the cock inside him continuously twitching, pumping Severus' seed into his womb, he shivered at the feeling of being bred. Deft fingers ran through his hair and his back in comfort, rubbing the tension away.

"Potter? Are you alright?" Severus asked gruffly.

Harry couldn't stop the chuckle that left him, his voice hoarse from overuse. "Just peachy professor," he replied breathlessly, not bothering to move from where he lay on his stomach on the desk. "Back to Potter, now are we?" he teased.

Severus snorted and ignored the obvious gibe, "We will be stuck like this for another 20 minutes. Do you feel any discomfort?"

Shocked by the concern lacing his professor's voice, Harry shifted and angled his head to look at his professor who kept running his hands over the Omega's back almost unconsciously. He stared into those onyx eyes and regarded his response. "I'm okay for now. Can't feel my legs though. " Harry replied sheepishly.

The professor smirked smugly at the knowledge that his mate was so thoroughly wek and blissed out from their mating. Gently, he hefts the smaller body in his arms and maneuvers their attached bodies onto a chair, settling the Omega on his lap. The change in position caused Severus' cock in deeper, nudging Harry's prostate none too gently. The sudden orgasm made his body tense, his back arching, head thrown back, mouth open in a silent scream as he milked Severus' cock. The Alpha sighed in pleasure and wrapped his arms around the lithe body of his now mate. He closed his eyes, burying his nose to inhale the lovely scent mixing with his own thinking back to how they got into this position in the first place.
