FORBIDDEN LUSTS

BRITTANY'S POV

"We're gonna start with the basics, Miss Jackson," His deep voice resonated in the empty classroom as I felt his hand traced my bare ass cheek.

I shuddered at the contact, my teeth grinding together as I tried to keep myself from moving despite the way my knees ached. The wooden edge of his desk bit into my skin since I was bent over it, my skirt raised high so my ass was bare and vulnerable.

Yes, I had gone back to his office on Monday to say that I failed his assignment and needed a private lesson so I could understand.

Maybe learning cells was actually really difficult and I needed help ㅡ Wrong, it was the easiest shit I had ever seen but we didn't need to know that, did we?

"Yeah?" I answered breathlessly.

His palm met my sensitive thigh with a loud sting that made me yelp. "What did I say, Miss Jackson? No talking until I permit you to do so..." His fingers rubbed slow soothing circles on the place he had hit, trying to ease the pain that shot through me.

I groaned, knees buckling but I kept my lips zipped shut.

He needed obedience, I had chosen this, I could comply with what he needed.

When I had gone silent apart from the occasional body shudder, his fingers found it's way to my ass again, teasing at the crack.

Without thinking, I stiffened, feeling a finger press against the rim of my ass. Fuck, I had never had anything back there before and I wasn't sure what to expect. My heart was practically bursting out of my ribcage but I kept my words in my throat, refusing to ruin the moment.

"First time?" Mr Allen asked, his breath hot against my ass as he leaned forward, using both hands to spread my cheeks about.

For a second, I wasn't sure what to expect but I hummed in agreement, not trusting myself to say anything. Thenㅡ

"Holyㅡ" I gasped, feeling his tongue slightly tease my puckered hole.

What the fuck was he doing?

I almost shot up but his hand pressed me back down. "Relax," He groaned against me. "I'm trying to help you so that it doesn't hurt too much when I'm ready to take you, Brittany."

At that, I relaxed, taking deep breaths as his finger gently pushed in past the first ring of muscle. I stiffened, feeling an uncomfortable pressure in my ass, as well as a sharp pain shooting up my spine but I bit down on my lip, refusing to give up.

No pain, no gain. Was that not it?

"Good girl..." I heard him mutter, keeping his finger still for a second before he wiggled it about, giving me a little stretch.

"Professor Allenㅡ" I groaned, feeling him curl his knuckles in me before another finger pressed in and holy shit.

"No talking, love," He warned.

Biting down on my lip, I let him wiggle his fingers around for a minute before he was pressing in another finger but this timeㅡ This time, I felt a tingle of pleasure begin to build up in my guts.

Oh fuck.

He stretched me wider, thrusting his fingers deeper. "C'mon, take me deeper. I'm way bigger than three fingers, Miss Jackson. C'mon..."

Without thinking, I found myself bucking back to meet his fingers halfway, relishing the pressure in me as my pussy dripped with desire. "Pleaseㅡ"

He suddenly pulled out and I gasped, breathing heavily. "You've been a good girl, Brittany. I think you're ready..." I heard the rustle of fabric and I froze, my heart thudding and air brushing against my ass.

I wasn't sure I was particularly ready yet but I certainly wouldn't deny the excitement that filled me at the thought.

The head of his cock parted my pussy lips, lubricating himself with my juices before he was tracing up to my ass, head teasing my puckered hole.

"Look at you," He groaned, slapping his bare tip over my clit again, the action making me yelp. Then he was back at my ass, tip pressing in this time and I could swear that he was about to tear me in half.

One of his hands snaked into my hair, gripping the strands lightly while the other guided his dick into me.

"Oh fuckㅡ" I felt my lips wobble, fear gripping me as he pushed in even further.

No way he was going to fit.

But he didn't stop. His hips moved forward at a slow pace, burying himself inch by inch until his hips were pressed against mine.

Then, he tapped my ass. "There you go."

I let out a shaky exhale, a tear rolling down my cheek as I felt his dick stretch my tight hole perfectly, the sensation stinging yet so erotic. 

"How does my cock in your ass feel?" He asked, giving me a sharp slap on my asscheek again.

With a shaky groan, I nodded eagerly. "Please... move..."

He wasted no time. His hips slid back, dick pulling out of me slowly before he was pressing back in.

"YesㅡYes... Fuck, why does that feel so good..." I found myself moaning, wanting to feel more than he was giving me.

His hand left my hair, fingers tracing my spine as he spread my ass cheeks apart. "Fuckㅡ" He muttered under his breath.

"Please..." I groaned, unsure what I was begging for.

"You like that? You like feeling my cock in your ass?" He asked breathlessly.

His strokes increased and soon, he was snapping his hips into mine, the wet sounds of his balls slapping against my sopping pussy echoing in the office.

"Say my name," He groaned, his next thrust so harsh that I felt my body slide up the desk, the furniture trembling.

My brain blanked and I struggled to find the right words to use. "Fuck, Mr Allenㅡ" I moaned, finally finding my voice.

He didn't say anything again. All that filled the space was his harsh breathing, my breathless gasps and the sound of our skin slapping.

Holy shit. This felt too good to be true. He was bigㅡ too big. I actually felt like he was pressing against something in me and I could swear he was going to make me black out from the pleasures my body received.

Almost immediately, like he could read my thoughts, a hand closed around my throat, cutting off my breath supply as my vision blacked. "C'mon, baby. Come for me," He ordered, snapping up harder.

I choked around his hold, feeling pleasure build in my guts. Then his other hand reached under me to tease my clit, finger pressing into my pussy while he kept up the pace.

That was it for me.

I saw stars behind my eyes, my legs buckling as my orgasm crashed over me. "FUucKkk..." I yelped, lips parted in silent ecstasy.

My pussy clenched around his finger, my ass walls tightening around his dick one more time before he went rigid, nails digging into my flesh before I felt warmth explode in me.

"Fuck..." He groaned, thrusting lazily in me before he pulled out. "Fuck. Clean it up."

Immediately, I turned to him, almost instantly crumbling to my knees, hands reaching up to take his softening dick before placing it into my mouth. 

This should be disgusting. His dick was literally just in my ass. But I could think about was his dark gaze through his glasses down at me, finger stroking my cheeks so softly while I gagged on his cock, eager to please him.

"That's it. Good girl," He purred, pulling out of my lips, leaving me gagging.

Unable to hold myself, I crumbled to a heap on the floor, coughing violently while cum trickled out of my ass, staining my skirt. "Is that my last lesson?" I managed, taking a wheezing breath.

He reached for the napkins on the table to wipe himself and me alike. "Last? No, Miss Jackson. We're just getting started."

Dizziness washed over me and I just sat there staring at him.

It wasn't the end of the term yet. A smile curved my lips. I still had a lot of lessons and I was more than happy to indulge in them.
