After a semester of minimal sleep, never, and I mean never, going to bed alone , the school year was drawing to a close. My five charges, young European girls were completing their studies and were all poised for graduation and unleashing on an unsuspecting world. All but Petra. She was due at my apartment in five minutes. I wasn’t worried that she wouldn't pass, in fact, like her four classmates, I was certain that she would fly through this with ease. She was a highly intelligent girl, of Irish extraction, and, I must admit, I loved hearing her talk. Irish accents have always been a turn-on for me.

Petra stood five foot four inches tall. She had shoulder length red-orange hair, freckles, pert pointed breasts topped with the most delightful puffy nipples. She had a deceivingly innocent look, appearing much, much younger than her actual years and a hometown charm that I had not seen in a woman, in years. I was looking forward to this evening’s activity with a growing hard-on tenting my khaki’s. Her assignment was to seduce me, fuck me senseless, and show me how she would extract information from me.

There was a gentle knock on my door. I opened it and was delighted to see Petra decked out in her school uniform standing before me. She wore black patent leather shoes, white knee socks, a green plaid kilt, white blouse, and a plaid tie, loosely knotted around her neck, red-orange lipstick and her hair in pig-tails. Her four classmates had opted for the older, more sophisticated look for each of their finals, but I was happy to see Petra dressed like this. My cock twitched in anticipation. She looked way younger than her years. I was going to enjoy this!

“Come in Petra.” I said as I stepped aside.

“Thank you Professor.” She replied shyly as she stepped across the threshold. I stared at her ass as she passed, recalling how round and soft it was from previous nights over the past year.

“Please, call me William. There’s no need to be so formal anymore.” I said as I watched her walk in. She had an absolutely stunning ass! I couldn’t wait to get my hands on it! “Have a seat. Can I get you something to drink?”

She sat demurely on the couch, opposite my easy chair, her knees touching, hiding her charms from view. “A glass of white wine would be fabulous Prof.. I mean William.”

I poured each of us a glass and sat next to her. Clinking glasses, I said, “To your impending graduation.” Her free hand rested on my thigh. I smiled, knowing that sooner or later it would start to creep up. Deciding to extend the foreplay, I said, “So, what made you decide to go for the schoolgirl look?”

“I spoke to the other girls and they had decided to go for the more glamorous look. I wanted to be different.” She said, as her hand floated up toward my crotch, cupping my balls through the fabric. “I think it worked.” She added, smiling at me as she sipped her wine.

This was not the first time she had come to my apartment for sex. She, and her classmates had all been here for ‘extra-curricular activity’ on numerous occasions, but this was the first time for her to take the lead. I had instructed her on the how-to’s of pleasing a partner. Now it was her turn to show me what she had learned.

I heard the almost silent ‘zzzz’ of my zipper being opened as she put down her wine glass. Leaning into me, her lips almost touching my ear, she whispered, “Tell me something so filthy, that it turns you on just to say it.” As I turned to her, I felt her hand reach into my pants, pulling my erection free.

I whispered my reply as our lips brushed. “After we fuck, I want you to make me eat you.”

“Perhaps. If you’re a good boy, I might let you taste me.”

Her tongue darted from between her lips, moistening mine before plunging into my mouth. Her grip on my cock firmed as she slowly caressed it from base to tip. Her small hand was barely able to surround the rock hard flesh of my manhood, feeding the lust building within me. Her lips mashed mine as our tongues fenced; hers thrusting into my mouth, mine parrying and pushing against her teeth.

I groaned into her mouth as she played with my shaft, her thumb circling the tip, smearing pre-cum all around the plum colored crown. I wanted to rip her clothes off and roughly fuck her on the spot, but this was her show, so I resisted the temptation, letting her set the agenda, as well as the pace.

Her free hand, now had a fistful of my hair, holding me in place as we continued kissing. She sucked on my tongue as if it were a cock. I moaned into her mouth, my manhood twitching with anticipation and need.

Finally breaking the kiss, she lowered her face to my member, ovalling her mouth and allowing my prick to slip up inside. The heat and humidity made me shudder with pleasure as I felt her lips clamp over the base of my cock. I felt her tongue swirl around as she lifted her face, the helmet springing free.

Smiling up at me, she said, “Want more?”

Smiling back, I saw the imprint of lipstick on base of my cock. “God, yes!” I hissed lifting my hips from the couch, in an effort to get back inside her face.

“Patience, William. The night is still young!” she said before kissing the leaking helmet. I watched in awe as her lips floated down toward the lip marks and my cockhead caressed the roof of her mouth.

“For Christ’s sake, don’t stop!” I groaned, watching her head bob up and down, her pigtails dancing as her head moved. I was getting dangerously closer each time her lips pressed the underside of my head.

Popping off briefly, she said, “Cum for me, daddy.”, then immediately clamping her lips around my saliva covered shaft.

“Oh God, Petra. Gonna cum!” I said breathlessly, looking down at her pretty face as she turned to look up at me, my cock now resting on her exposed tongue. I grunted as my cock spat gob after gob of warm, white sperm. Her eyes twinkled as I emptied myself into her mouth.

I slumped back onto the couch as she sat up, mouth closed, kissing me on the lips. Her tongue slithered out, greasy with semen, pushing into my mouth. I opened up, letting her in. She opened up, letting my cum flow freely from her mouth to mine before shoving her tongue deep and taking some back.

Smacking her lips as she broke the kiss, she suggested we retire to the bedroom. Sensing that it really wasn’t a suggestion, I agreed. “Whatever my Mistress wishes.”

Once there, she told me to strip and lie on the bed. Quickly disrobing, I did as I was told, lying on my back, my cock re-stiffening as I watched her. Petra unbuttoned her blouse, exposing a plain cotton bra that conformed to her young figure. I could sense, more than see, her puffy nipples as they strained against the thin fabric of her bra. The sight made my cock twitch in anticipation, even though I had seen her naked before. She crawled up from the foot of the bed, her breasts brushing my abdomen. I could smell my cum on her breath as she whispered to me. “You tasted so good, Daddy” She took each hand and secured them with the ropes I had attached to the headboard.

“And I can’t wait to taste you, Petra.”

“Patience, Daddy, we have all night!” she said as she fastened straps to my feet, leaving me spread open and helpless.

She crawled up between my legs, taking my left testicle in her mouth, her tongue swirling around it as she stroked me to full hardness. “When I’m done with you, there will be nothing left in these!”

“So, what’s your plan Petra?” I asked as I watched her slide her blouse off her shoulders.

“Shhhh!”, she said, adding, “You are not to speak unless spoken to!” She straddled my cock, rolling her hips, rubbing my member against the gusset of her plain white cotton panties. I groaned as the dampened material caressed my hardness. “What are you willing to give me, just so you can fuck me, Daddy?” she asked, slipping her bra off and baring her chest.

“I could give you an “A”.”

“I’ve already earned that!” she replied, grinding her panty clad cunt against my shaft. “You could give me your cock.”, she added, as she leaned over, her pointed breasts inches from my face.

I stared at her puffy nipples for a moment before lifting my head and trying to capture one with my lips.

“Unh UnhUnh!” she said backing up just enough to be out of reach. “Not without permission!”

“Please Mistress Petra! May I suck on your nipples?”

Crossly she answered, “What did I tell you about speaking out of turn?” Rising off my painfully stiff cock, she peeled off her soaked panties and held them above my face. “Do you want to smell me? Taste me?”

“Yes mistress! Please?”

She draped the wet gusset across my nose and stuffed the rest into my mouth, effectively gagging me. “I am going to fuck you, slave. Don’t cum without my permission! Do you understand?”

Unable to speak, I nodded, still sucking on her panties and breathing in her bold scent. I could not see, only feel, as her cunt sheathed itself on my cock. Her face took on a distant look as I sank into her molten depths. As she rose and fell, I could feel her cunt muscles rippling against my cock. The sensory overload was excruciating. Smelling her, tasting her and feeling her heat, her humidity was driving me toward a mind shattering orgasm. But, as she was driving me, I was driving her, banging against her clit. Her breath caught in her throat, her fingers dug into my chest, her cunt clasped my cock, as she came.

She lifted herself off me, smiling as she looked at my honey coated cock. She turned and pulled her panties from my mouth. “You can’t very well eat pussy if your mouth is already full. You do want to eat me, don’t you?”

“Yes, Petra. Please?”

“And remember, you do not cum without my permission!” she added as she settled herself onto my face. My tongue sought out her inner lips, drinking her aromatic and tasty juices. Then I felt her tongue as it licked up the essence deposited on my cock. She worked her way from tip to base, sucking my testicles into her mouth, bathing them with her tongue. After letting them plop from her mouth, she engulfed my hardness completely, my helmet bumping the back of her throat.

I could feel my own orgasm slowly rising, but, try as I might to think non-sexual thoughts and keep it at bay, I knew I was going to lose. I began to moan into her ripe, wet cunt, trying to relay my urgency and still follow orders. She allowed my cock to slip from her mouth. “You aren’t thinking of cumming are you?”

“MmmHmm!” I moaned between licks of her engorged clit.

“Well, you aren’t!” she snapped as she pinched my cock.

I groaned in pain as my manhood deflated. “Keep licking!” she said as she ground her cunt into my face. “Make me cum!”

Returning to her clit, I bathed it with my tongue, flicking across it, alternated with broad doggy kisses. “Yes! Yes! Fuck, yes! Don’t stop!” she screamed between sucks on my re-hardening cock. She repositioned herself slightly allowing my tongue to penetrate her cunt and my nose to press against her sphincter. Rocking her hips, she soared toward another orgasm, my tongue rasping against her clit, her outer lips and her ass. “Oh fuck! That’s it!” She cried as her cunt began to weep, dripping onto my nose, my chin, and into my mouth.

I drank what I could, the rest washing over my face as she trembled through it. Panting, she rose, turning toward me. “You want to fuck me now?” She leaned into me, kissing me, tasting herself.

“Yes please.”

“As long as you don’t cum.” She reached down, clutching my shaft, guiding it into her warm wet snatch. She leaned back and began to rise and fall, my helmet scratching at her g-spot. She noticed my stare and smiled. “You like watching as you fuck, don’t you?” she said, adding, “Watching as your cock invades my cunt.” I could feel her muscles as they rippled around my shaft. “Feeling me caress you, urging you to cum inside me.” She leaned forward, dangling her pointed breasts just out of reach of my lips. “I know you want to breed me, Daddy.” I groaned my response. She ground her clit against my pubic bone. “Don’t you want to see me pregnant?” Again, I agreed. Anything to let me cum.

I let out a groan, no longer trying not to cum. I didn’t care! “Petra, let me cum, please?” I begged.

She leaned a little lower, letting me capture her nipple. I began to suckle. Suddenly she moved letting my hardness slip out, plopping against my belly. “No!” she whispered in my ear, “Not yet!” I felt her pinch just behind my helmet, immediately deflating me. The frustration was overwhelming. I groaned again, feeling her hand surrounding my manhood, sliding up and down, bringing it back to life.

“Are you ready Daddy?” she purred. My lips pursed around her nipple, I nodded. “Are you ready to be a Daddy?” I felt the mushroom head slip inside her. The heat, the tightness, too much to bear “Cum inside me Daddy!” she demanded as I felt my balls rub against her, my cock completely enveloped inside her.

“Mmmmffff! Mmmmmffff! Oh god! Cummmminnnggg!” I screamed into her left breast. I could feel the sperm shooting deep in her womb. I bucked up into her, lifting her from the bed. I nearly passed out from the pleasure as I kept pumping her full of my seed. At some point, she had unfastened my feet and hands, so I was able to enfold her, keeping her close and unable to get up.

“Roll me over on my back, Daddy.” She said, “I don’t want your cum to leak out!” So, we rolled over without disengaging, my head now resting on her breasts as my cock lost its firmness and slithered out of her battered, leaking cunt. “Now I want you to eat your own cum.”, she said, “But not all of it!”

I kissed my way down her belly, sticking my tongue in her navel as I worked my way down to her pussy. Once there I slurped up a dollop of cum that was desperately trying to escape from within, the salty taste a pleasant surprise as it rolled across my tongue and down my throat. I spent the next ten minutes caressing her clit and swollen cunt lips with my lips and tongue, enjoying the mixture of her honey and my cum.

Pulling at my head, she urged me to kiss her, wanting to taste us just as much as I did. We lay there for several minutes swapping back and forth, before she asked me how she did on her final.

I smiled down at her and said, “You did well! Not an ‘A’, but you did well.”

A look of consternation and surprise crossed her face. “Why not an ‘A’.”

Thrusting my re-animated cock back in her, I replied, “There’s still some cum left in these old balls, Petra!”
