Time to fuck

Seeing the look of satisfaction on her face after my oral ministrations, it looked like she was primed and ready for me to slide my dick inside that tight tunnel of hers. I stood up and told her to take off her shirt as I began to unbutton mine and soon had my first view of her young, perky tits. They were a perfect handful with rose-colored, quarter-sized areola that were centered on each breast. Her nipples were hard with arousal and pointing straight up at me and I couldn't help but reach down and fondle them. Her warm, soft flesh filled my palms and I rolled her nipples between my thumb and forefinger, watching as they grew even harder and she gasped from the pleasure.

"Fuck me, David," she whispered, her voice needy and full of lust. "Please, I need to feel you inside me."

Her begging was music to my ears and I didn't waste any time. I pulled her to the edge of the couch, making sure she was spread out just right before I positioned myself between her legs. I looked into her eyes, watching as they went wide with anticipation as I lined up the head of my cock with her opening. She was so wet that the tip slid in easily and she gasped at the sensation. "Oh God," she whispered, her eyes never leaving mine as I pushed into her slowly, giving her time to adjust to my size.

Once I was fully seated inside her, I paused, savoring the feeling of her tight, college-aged pussy gripping me like a vice. Her legs were spread wide though, an open invitation for me to do what I wanted to her and I leaned forward, placing my hand down on the couch to support myself. With a groan, I began to slide in and out of her, setting a slow, steady rhythm that quickly had her moaning "yes, yes" as the wet sounds of our love-making started to fill the quiet office.

I had forgotten how tight a college-aged pussy could be, and Kelsey's was exquisitely so. With each stroke, I felt the muscles of her hot, slick, velvety walls contracting around me and I had to fight the urge to go harder, faster, knowing I needed to make this last. I could see she was responding to my technique, her toes were curling and her breathing was growing more ragged by the second.

"Oh fuck David, your cock feels so big," she murmured, her voice a breathless whisper as I fucked her with a rhythm that was gradually bringing her closer and closer to the edge. "So much bigger than anyone I've been with. God it's so fucking good!" Her words were a heady mix of praise and pleasure and I felt myself swell even more inside her.

As I picked up the pace, my balls started slapping against her ass with every hard thrust. The sight of her tits bouncing in time with our fucking had me groaning with need and I reached down to start rubbing her clit with my thumb. Kelsey let out a sharp gasp and threw her head back, and I felt her pussy starting to quiver around me as I brought her back to the peak of pleasure, her walls tightening even more around my cock. "Oh fuck, oh yes! Yes!" she screamed out a second later, her body convulsing in another powerful orgasm that had her nails digging into the couch cushions and her pussy contracting like a fist around my dick. Her juices flowed freely once again, coating my cock and leaking onto my balls, making the sounds of our fucking even wetter and more obscene.

I kept up my efforts, intent on prolonging her orgasm for as long as I could, my hips moving like a piston as I slammed into her over and over again. But eventually the intensity of her orgasm must have become too much for her because started begging me to stop. "Oh David... Stop... Oh god, please stop!" she told me between breaths, her voice hoarse from her screams of pleasure. "I just... just need a minute."

I slowed down and leaned forward to kiss her neck then murmured into her ear "I know we're supposed to be professional here, but you're so fucking sexy when you cum, Kelsey." I told her, my voice deep and gruff.

She turned her head and looked over at me, her eyes glazed with pleasure, a small smile playing on her lips. Her voice was a mix of disbelief and awe as she whispered, "No one has ever made me cum like this David. How are you still going?" Her eyes searched my face, looking for an answer, but all I offered at first was a smug smile.

The dozen or so additional years of sexual experience I had over her, as well as a good handle on my sexual stamina meant I could easily last longer than the college boys she was used to, but I definitely had my limits and knew mine was rapidly approaching. "It's taken all my willpower and self control to not cum yet Kelsey. Your pussy feels incredible, but I told you that you deserved to be with someone who satisfied your needs and I meant it."

"Mmmmmm, well you definitely did that." she said grinning at me while moving her hips into mine. "But if you've still got it in you and it's not too much to ask, I do have one more fantasy I'd like your help with." She said, looking at me with a mix of excitement and nervousness.

"Oh, and what's that?" I asked, my interest peaked.

She looked at me shyly before speaking, "Well, all week long, every time I've been in this office, I've pictured you bending me over your desk and taking me from behind, and... " her voice trailed off, her cheeks flushing a deep shade of pink with her unable to look me in the eyes.

There was something else she wanted, but wasn't ready to voice it just yet so I climbed off of her then took her hand and helped her to her feet. I walked her to my desk then gave a nudge to her back, bending her over the edge so that her forearms were resting on the cool surface and giving me my first view of her incredible, naked ass. It was as perfect as I thought it would be and I started to caress it after I lifted her left leg and knee onto the desk as well, spreading her wide as I lined my dick back up with her opening. "Is this how you pictured it, Kelsey?" I asked, my voice low and gruff as I slid myself back inside her then began thrusting in and out of her slick sheath.

"Oh fuuuuccccckkkk!" she moaned at the sensation from the new position. "Yes, this is just what I pictured!"

"And what else did you picture me doing?" I whispered, my hand reaching down and around to squeeze her right tit. "What's the rest of that fantasy?"

Her response was a moan, and I felt her pussy tighten around me. "I pictured you... you... cumming on my face," she finally managed to blurt out. The words sent a jolt through me. It wasn't what I was expecting her to say, but the idea of marking her with my cum was incredibly hot and I started hammering into her with increased urgency.

Her moans grew louder, filling the room as I picked up the pace. I could feel the pressure rapidly building in my balls letting me know my release was imminent. "Shit, Kelsey," I grunted. "You want me to treat you like a dirty little intern and cum all over you!? You've got it." and with that, I pulled out of her, began rapidly stroking my member, and watched as she quickly dropped to her knees in front of me. She was so eager, her eyes never leaving my cock, as she presented her face as my target.

The pressure continued to climb until I finally reached my pinnacle, letting out a loud groan as the first rope of cum exploded out of me and splashed across her face. She closed her eyes, but never flinched away, keeping her face tipped up to the ceiling with a content grin on her face and giving me a perfect canvas to cover with my seed. I couldn't believe the amount of cum I was producing; rope after rope of my sticky, white sperm painted her face, leaving streaks on her flushed cheeks, her nose, mouth, and chin, and coating the lenses of her glasses.

When I was finally finished and my balls were drained, I looked down at Kelsey and took in the site of her face covered in my cum. She looked like a pornstar, an absolute mess with her glasses fogging up with the heat of my cum, but she was grinning up at me like it was the best thing that had ever happened to her then started licking her lips, savoring the taste of me.

I couldn't help but chuckle, and reached out to help her back to her feet, handing her some tissues from the box on my desk. She took them gratefully, wiping her face clean before tossing them into the trash. "Wow," she said with a giggle, "I didn't think there was going to be so much."

"Guess I was a little pent up," I said with a wink. "But I have been saving myself for you all week."

Her giggle was light and airy, then she wrapped her arms around me and placed a kiss on my chest. "Oooh, I'm glad you did. It's definitely not what I was expecting when I started this internship," she said, "but I'm not complaining at all."

"Good," I told her with a smirk, "I wouldn't want to get a poor review from you on my performance as your instructor."

"Oh, I don't think you need to worry about that at all," she told me with a wink, her voice still a bit shaky from the pleasure I had just given her.

"But seriously, Kelsey," I said, holding her at arm's length and looking into her eyes. "I hope you now saw that you can have great sex without being in a serious relationship. You're smart, sexy, incredible in bed, and you should get out there and enjoy yourself without any strings attached." I told her, hoping that I was effectively conveying that this thing with us was a one time thing.

"Oh, I realize that now David," she responded, her voice filled with sincerity. "You've really opened my eyes, and my pussy, to what I've been missing out on. I think I'm going to have a lot of fun exploring my inner, slutty side from now on." Her cheeks were still flushed from her recent orgasms and she had a look of pure contentment on her face and if I didn't have my wife waiting for me to get back home, I probably would have considered taking her again right there.

But I did and instead, moved away from her and started gathering our clothes. I handed hers back then started putting mine on, signaling an end to our tryst. She took her clothes with a soft "Thank you" and started to get dressed herself, her movements still a little shaky.

Once we were both dressed and looking moderately presentable, we shared one final kiss before I walked her to the door to my office. "I want to clean up a little more around here, but you should get going. It's probably better if we leave the building at different times anyway." I told her.

"Thank you. For everything, David," Kelsey said to me before giving me a final hug then she gathered her belongings and started walking down the hall towards the elevators. She had a spring to her step and I admired the site of her ass for a few final moments before moving back inside my office. Though the air smelled of sex, the room itself wasn't too much of a mess and I was able to straighten things up fairly quickly and was ready to head home in only a few minutes. I made one last stop by the bathroom to wash off any possible evidence of my infidelity from my cock and balls then made my way towards the exit and back to reality, my needs satiated, at least for now.
