I rasped my knuckles against the frame of the wooded door that stood before me.

Anticipation swirled in my stomach as well as that tempting excitement that came whenever I knew I was going to come in contact with him on school grounds. The true forbidden nature of our relationship shinned in those moments and I couldn't deny the heat that began to pool in my lower stomach at that very wrong, very naughty thought.

"Come in." His deep, strong voice called out from the other side of the door, sounding as the prime example of a no nonsense, strict professor. And I'll be damned if that tone didn't just urge me on even more to break that professional mold of his and break some rules at the same time.

I placed my hand gingerly on the handle and turned it, opening the door wide into his office. My eyes were instantly drawn to the man behind the desk whom had yet to look up and see which student had just entered his office.

Smirking to myself coyly, I shut the door behind me, the click of the door closing echoing through the room.

"Excuse me but would you mind opening the door back up?" He asked, his attention still engrossed in the papers on his desk.

"Are you sure you want me to do that?"

Finally, Nathan's focus was ripped away from the papers in his hands and pinned on me.

His entire face lit up and my favorite lopsided grin formed on his lips. Something entered his eyes that had been more than prevalent the last couple of days ever since he had his talk with Dan.

I wasn't sure what they had talked about but all the rest of the night and ever since then I would find Nathan staring at me with a sort of glint in his eyes that I just couldn't place. Yet, it was a look that struck my heart powerfully and made it squirm and leap in response.

Nathan leaned back in his chair, relaxing his body while keeping his playful eyes locked onto mine.

"You know it's against the rules to have your office door closed with a student present inside."

"You know it's against the rules to make out with a student in your classroom too, but that didn't seem to stop you then either."

"Touché," he said with a knowing smirk.

I moved away from the door and casually strolled through his office, taking in its surroundings.

"So this is your office." I stated as I walked over to the wall where two diplomas were hanging and inspected them. Neither of them were Nathan's but in fact Mrs. Smiths.

"It is. For about three more days that is."

"You know," I let my feet guide me over to his desk slowly, adding a very noticeable, teasing sway to my hips. "It's a real shame that I haven't come here sooner. We could have had some real fun in here during school hours."

I planted myself directly next to him, leaning my backside against his desk. His eyes met mine, lust brimming within them. He folded his muscular arms over his chest.

"Don't you think we take enough of a risk as it is?"

I sighed and shrugged my shoulders. "I guess. I just thought that maybe you'd be up for pushing the boundaries a bit more. Adding some thrill to the relationship. But, I guess you aren't up for the challenge," I said overly dramatically, knowing that I was pushing every button on him that I could.

I sighed once again, very audibly and stepped away from his desk. But before I even made it a half step away, I felt hands grab onto my hips and roughly pull them back until I fell back over his legs and found myself sitting in Nathans lap.

"Now, that's a load of horseshit and you know it," He tutted at me in a very professional manner like he was scolding a misbehaving student.

"Mr. McCoy! Language!" I perked up on his lap and pretended to be appalled with his vulgar language, while internally I was dying laughing at this entire role-play that we had just begun; that and simultaneously becoming extremely aroused.

"Ms. Merrick, I can talk to you however I please, and you'll do damn well to remember that." His stare screamed with intensity and undiluted desire.

"Or what?" I maneuvered myself off of his lap only to slide my knees onto either side of his hips, effectively straddling him.

"Are you going to punish me, sir?" I asked as innocently as I could but the writhing need that was growing inside of me forced my voice to come out breathy and low.

Nathans hands came up to grab onto my waist, squeezing at the fabric of my shirt and the skin underneath. His lust filled eyes looked up to find mine.

"You are going to be quiet now, Ms. Merrick. No sound will come from you whatsoever, yes?"

"Yes."

He cocked his head to the side. "Yes, what?"

My breathing faltered and my body was beginning to overheat when I realized what he wanted.

"Yes, sir."

If possible, Nathans eyes darkened another shade and my core throbbed even harder.

Then, without hesitation, Nathans rough, large hands were under my shirt, kneading at the skin that he came in contact with.

"Arms up." He instructed.

I obeyed.

I lifted my arms up above my head, keeping eye contact with Nathan the entire time as his fingers trailed up my bare skin as he slowly lifted my shirt up and over my head.

Now my black laced bra was the only thing covering my upper-half.

Nathans eyes fell to my generously sized breasts and his chest heaved up and down as his own breathing intensified.

Agonizingly slow, I felt his fingers graze up my bare torso, taking his sweet time until he finally reached where my bra was, covering up what I knew he most wanted on display next.

One of his arms wrapped itself fully around my waist as the other was fully occupied with another part of my body entirely.

His hand brushed across the material of the bra and my nipples instantly came to attention at the mere touch. Nathans lips came in contact with my stomach unexpectedly as his hot breath washed over my skin. I watched as his tongue peeked out and made it's way up my waist, leaving a trail of boiling lava wherever his teasing tongue had just touched. His lips came together and kissed my stomach, in long, hot, open mouth kisses just underneath my bra. My head rolled back as my eyes closed, focusing only on the pleasure that Nathan was giving me.

I was far too intent on Nathans assault on my stomach that I had almost forgotten about his other hand that was meticulously running across over top of my bra. So when his fingers poked underneath the underwire of my bra suddenly and brushed against one of my nipples it was almost impossible to stop the gasp from erupting out of my mouth at his touch.

His fingers left my highly excited breasts and his lips came to a stand still on my stomach.

Nathans head rose over so slowly until his chin was resting against my stomach and his hooded eyes pierced through mine.

"I said no noise."

"Sorry," I breathed, still too caught up in the moment to really mean it.

Again, Nathan cocked his head to the side and his eyes pinched at the sides as he observed me.

"I don't think you really mean that, Ms. Merrick." He once again sounded just as he did in class and he disapproved of something that a student had said; just a bit more intense.

"Stand up."

I did as he said, moving myself off of his lap and stood before him clad only in my jean shorts and black bra.

He stayed put in his chair for a bit, watching me as I stood there, his eyes traveling over every inch of my body. It also gave me a perfect view of the prominent bulge that was straining against his work slacks.

And then he stood. His height briefly caught me off guard as he stood tall directly in front of me, causing my head to strain back as I tried to keep my eyes on his hungry ones.  

"Turn around."

When I didn't immediately heed his instructions, he reached his hands out and I found the room spinning for all of two seconds before his office door came into view and I felt Nathan's body press up against my back. The force of his body pushed my own body forward and my hands came out to save me from face planting into his desk.

I was now bent over Nathans desk, ass out and shoved right up against his stiff erection.

"Now, what exactly should I do to you, ms?" He asked. His hands both circled around my waist but didn't stop there. No, they went until they met on the center of my jean shorts; at the button to be more specific.

His thumbs started playing with the button that was the only obstacle in his way from reaching my heated center.

He popped the button open.

He ever so gradually slid the zipper down.

His hand slipped underneath the band of my underwear, caressing my skin softly, teasing me endlessly with his awaited touch. My breathing was coming out in short bursts and I was subconsciously arching my back, urging his actions on in approval as I shamelessly ground my hips into his erection, causing him to thrust his hips forward forcefully into mine.

Then, my prayers were answered when his fingers slipped into me, eliciting a throaty moan from Nathan.

"I think you are enjoying your punishment far too much, Ms. Merrick."

His fingers started working me into a writhing frenzy of pleasure. Bolts of desire shot down my legs with every twitch of his fingers making it near impossible to stand on my own. My knees were beginning to buckle and Nathan finally took notice of my struggle.

He reluctantly withdrew his expertly trained fingers and turned me to face him. His eyes were the perfect picture of passion and lust mixed into one, which I was sure only reflected my own.

My need to return the favor took over every other rational thought that I had as I dropped to my knees and grabbed for his belt. His hands covered mine and held them in place.

"You don't have to do that." Nathans eyes bored into mine as truth shone through his sapphire colored eyes.

Staring up at him from my knees, I removed my hands from under his and resumed my task, pulling one end of his belt out from the buckle.

"I know. I really, really want to, sir."

He groaned deep within his throat as his eyebrows strung together and his head fell backwards when I brushed my finger tips gently across his hardened member through his pants.

I guided his pants zipper down-

"Mr. McCoy?" A voice called out from the other side of the door at the same time as their knocks ripped through Nathan and I's moment.

My hands froze as the breath was stole from my lungs. I frantically looked up at Nathan and he seemed to just as caught off guard as I was.

"Mr. McCoy? It's Abby!"

That annoying voice snapped me back into reality as I worked to cover the scowl that appeared on my face at the mention of her name and presence.

"Say something!" I urged Nathan in a whisper as I scrambled my head for ideas on where I could hide.

"Just a minute," he said and seemed to be having the same thoughts that I was.

"Under the desk," he commanded, a dominant essence rang out fluidly in his words.

Without question, I threw myself under his desk and he sat in his chair, scooting it forward to hide his ever present bulge. 

Now my vision was limited to the sliver of light that shinned through the one opening where unfortunately,  Nathans legs consumed most of the space. I was resulted to relying on my hearing to gauge what was going on.

I heard an exasperated sigh come from Nathan before he instructed Abby to come in.

"Hey, Mr. McCoy."

Her voice made my entire body cringe in disgust at her fake tone and innocent attitude.

"What can I do for you, Abby?"

"Well, I was hoping to talk to about that little indecent that happened on Friday."

I couldn't help but roll my eyes underneath his desk.

"That's not really necessary is it? I saw what happened and it's done and over with. No need to talk about it further." His tone almost had me biting back a laugh with the irritation that he was poorly trying to mask laced in his words.

"But I think you got a very wrong idea of the type of person I am and I just wanted to right that." Then, I heard her step closer to his desk. Seconds later, a creak sounded from above me as it seemed more weight had been put on it. Her voice was suddenly much closer than it was before.

"You see, I respect you a lot, sir. And I think it would be a real shame if you thought less of me when I personally think we have so much in common."

It was evident to me now that she was leaning on his desk, most likely trying to seduce him in some way.

My nostrils flared in anger once I realized what she had come here to do. An overbearing jealousy came over me as I wished more than anything that I could come out from under that desk and show her what Nathan was doing just moments before she slithered her way in here.

I knew I couldn't do that though. That was jeopardize everything that Nathan and I were trying to protect. But I wanted to; needed to do something in that moment.

And that's when it hit me.

A devilish smirk rose up on my lips as I scooted my way under the desk over to Nathans legs; over to Nathans still hardened member.

"Well, I'm sorry but I fail to see the comparisons, I-aah,"

I had to bite my lips so hard to keep from bursting out laughing at Nathans outburst when I ran my hand over his newly freed bulge. The only thing standing in my way now was his underwear, which wouldn't take me but a second to maneuver around.

"Are you alright, Mr. McCoy?"

"Yes- I just...hit my knee," he lied, and quite  poorly might I add.

Within seconds, I had completely freed his solid member as it popped out of his briefs and stood at full attention before me.

And let me tell you ladies and gents, he did not disappoint.

"Are you okay? Do you want me to look at it?"

"No!" Nathan all but yelled at her.

I wrapped my hand around him, the soft skin welcoming my touch as he twitched in delight.

Nathan let out a simultaneous sharp breath when I finally made contact with him. Suddenly, one of his hands came into my vision and covered my own hand to stop any further movement.

"Okay, well as I was saying..." Abby's ramblings droned on into the background. Nathan's hand tightened around my own, halting any further movement of my hand and I simply wasn't ready to give up quite yet.

I brought my lips closer to his erection, grazing them over the top and placing a kiss where my lips had just touched. Nathans hand gripped harder onto mine and moved to cover the skin that I had just become antiquated with.

Well we simply couldn't have that, now could we?

I brushed my lips over his fingers, my tongue poking out teasingly, running over his knuckles, his finger tips. And when he still didn't let go, well, lets just say I brought out the big guns.

"Shit!" Nathan exclaimed as he drew his hand away with a brand new pair of teeth marks as a warning. I only smirked in victory.

"Sir! What happened?"

"Damn...nail under the table scratched me or someth-aah," Once again Nathans sentence was cut off as I passed my lips over his erection and took all of him into my mouth.

"Are you sure you're okay Mr. McCoy? You seem awfully flustered." I heard Abby's voice ask as I continued my work on Nathan, unraveling him slowly with my hot mouth and teasing tongue.

His entire body tensed as I felt his hands grip onto his chair with an almighty force. His breathing was erratic and to any normal person, unknown to them what was occurring under the table, they would think Nathan was having a stroke.

"I'm fine. I think it best you leave now," he said as calmly as he could, yet the lustful strain was still ever present in his voice.

"But we haven't even talked! I thought we could maybe, get to know each other a little better," she said in what I assume she thinks was an alluring tone. Her attempt to seduce Nathan only caused me to work him harder and faster, bobbing my head up and down, taking as much of Nathans member in as I could.

"Oh, god..." Nathan moaned freely and then realized his mistake as he tried to cover it up as annoyance for Abby. "There is nothing that you and I need to talk about and we certainly don't need to get to know each other so if you will, please leave. I some business that needs to be tended to."

I internally laughed at his double meaning. I could tell he was getting close by the urgency that was accumulating in his demands for Abby to leave.

"Is there anything I can help you with? I'm very resourceful," she said and if I hadn't of had Nathans erection already occupying every inch of my mouth, I might have thrown up by her own seductive double meaning.

"Abby, stop! I am not interested in whatever you are trying to do here so just leave." His voice was hoarse and exacting and I was almost certain that Abby would leave after that. And yet, somehow she still had some fight in her.

"Please, sir. Don't pretend that you haven't been participating in our little flirting games. I know you want me."

And there's the real Abby!

"The only thing I want of you right now is to leave! You are desperate and a student and I am not interested in the slightest!"

Well, damn. His forcefulness and gruff composure turned me on even more if possible and I reached up and added my hand to the action, rubbing the base of his member vigorously, while my mouth was still busy at work.

"Sir!"

"Out! Now!"

Nathan couldn't hold his anger and frustration back anymore as he bellowed at Abby. Seconds later though, footsteps could be heard leaving and then his door was shut.

Nathan instantly pushed his chair out with his legs, bringing me with him as he brought his hands up into my hair, removing it from around my face and held it back.

I daringly peered up at him while I still had his length in between my lips and continued bobbing up and down as we made eye contact. Nathans face scrunched up in pleasure as his head fell back as he could finally enjoy the pleasure he was receiving.

"Oh, fuck."

I worked his erection with a new found purpose. Desire and excitement welled up in my core as his hips started thrusting into my mouth on their own accord.

"Alex..." He groaned, the sound vibrating through his chest. His hands grip on my hair tightened suddenly and I knew he was about to come.

I dipped my lips down over his entire member, gagging a bit on his length as Nathan let out one final primal grunt, one final hard thrust between my lips and came undone.

After a moment or two, I let his dwindling erection pop out of my mouth and stared up at a very euphoric, very sated Nathan. He was taking heavy breaths of air and a very lazy smile graced its way onto his lips.

"So, am I forgiven, Mr. McCoy?" I asked, referring back to our role play game from moment before Abby's knocked on his door, resulting in the most forbidden and exciting sexual experience of my and I'm sure, Nathan's life.

He lifted his head up off of the back of his chair and connected his eyes with mine. He shook his head tauntingly at me, his eyes filled with such mirth and joy at the same time. 

"You...are a very naughty, little minx."
