Stepsister’s Secret [M18] [F19] [Stepsister]

I was going to miss my stepsister when she left for university. Partly because she was good company, but mostly because she was all I had cum to since I was a teenager. She was tall, about 5’10, with long blonde hair that accentuated her slender figure. She was thin boobs and an arse that were small but shapely. Over the years she had gotten more comfortable, and I savoured every time she sauntered around the house braless or just in her panties. I would feel my dick grow and throb every time I caught a nipple poke through the fabric of her shirt, or a flash of colour as her panties poked out from under her shirt.

As she got closer to leaving she started to act differently. Sometimes I swore it was all in my head, but deep down I knew it was true. How touchy she’d become, how she began to tease me. I remember one morning she came up behind me and hugged me, her slender arms wrapping around my body. This wasn’t unusual, what was is how she disengaged. As she left her hug she dragged her arms slowly across my chest, gently applying pressure. Then she teased under the collar of my shirt with her fingers, feeling across my chest. She paused for a moment, before leaving with a skip and a giggle.

Teacher and Student

I was never good at physics, but I’d never failed before. Seeing that 20% on my paper as it was handed back only compounded on my misery. First my girlfriend leaves me, then I fail for the first time. The week felt like it had lasted months and would last many more. I turned my paper over as fast as I could, but others around me saw. Their laughs and jeers at my failure spread around the room through whispers and sneering until hopelessness took over my body. My only wish now was for Mrs Smith not to be too hard on me.
She was undoubtably the hottest teacher at the school, but I don’t know if she knew it. She certainly didn’t seem to, she was never the type to tease or play with the boys; or notice their dicks grow at the sight of her ass every time she turned to write on the board. Even some of the girls were in love with her, blushing and squirming in their seats at every “good job” and “well done” to come out of her lips. She dressed modestly, as a teacher should, but her body betrayed her. Her round ass and large breasts could not be contained, no matter what was over them. Every skirt she wore only enhanced her features. Every curve of her ass and the thickness of her legs seemed to want to escape it, even if she so desperately wanted to keep them in. It was summer, so she was forced to forgo her usual thick jumper (no doubt chosen to hide the fullness of her boobs) in place of a light jumper and button-up t-shirt. Every time I looked at that shirt my boner throbbed and pulsed. I so desperately wanted to pop each and every button on it and bury my tongue in her rack. But her attempts to hide her natural sensuality made her sexier. A prize to be won, even if everyone knew it was impossible. A fantasy to cum to every night at home in bed, wishing your cum would cover her face instead of being trapped in a tissue.
I desperately tried to hide my boner as class was dismissed but it pressed into my trousers, as if it was seeking Mrs Smith’s pussy. I was at the back of the class so I had time to calm down. That was until Mrs Smith walked over to me, gently rested her hand on my shoulder and softly spoke the words “I think we need to have a talk, don’t you?” Fuck. Now not only was my erection strengthened by her touch and sensual Canadian accent, I was in trouble. She pulled up a chair on the opposite side of the table and took of her glasses and hair tie, placing the glasses on the table and letting her hair fall over her shoulders. It framed her beautiful face in a way that made me want to touch ever last centimetre of it with my lips, her soft, delicate features were rounded in a way that spoke of reassurance and comfort. “What happened on this test then?”
Her words awoke me from my trance. “Look I’m really sorry, my girlfriend left me and I’m naturally bad at the subject – it all just became too much stress.”
“I’m sorry to hear that but you should’ve talked to me, I know I’m here to help” she said gently. “Listen, why don’t you stay after class this time next week, I can give you some help then.”
My mind was racing with teenage fantasies but I managed to stammer out an “O-okay Ma’am”.
I raced out of the classroom with a book covering my throbbing erection. I ran to the bathroom and gave my cock a few hard strokes before shooting out ropes of cum. I didn’t know how I was going to make it through the week when all I could think about was Mrs Smith’s pussy encasing my cock. Even the normal focuses of my masturbation didn’t interest me. Usually I would pull thoughts of my classmates out of my mind to cum to. Jessica with her tight ass and red hair. Grace, who always unbuttoned her shirt just enough for you to
catch some cleavage. But no. All I could cum to was Mrs Smith. There was no doubt in my mind nothing was going to happen, she wasn’t like that, but still my mind raced with the thoughts.
Finally the time came. I sat sheepishly in my usual spot at the back of the class as everyone left, waiting for a tortuous hour of physics made better only by my perverted fantasies. “Come up to the front of the class, sit with me,” Mrs Smith commanded. I tried to slide my notebook over my erection as quickly as I could, when I noticed something. My teacher looked at me out of the corner of her eye, shaking her head with a small smile on her face. That couldn’t be about what I think it is, right? I pulled up a chair and sat in front of her, this time with no desk to hide my boner.
“Look, I don’t think your problem is with physics,” she said. “I think you’re under too much stress.” I was shocked. I never thought this would be what her extra sessions were like. “I’m a firm believer that what’s going on in your brain affects your ability to study, so if I didn’t help with that I wouldn’t be much of a teacher now would I?” I was speechless. I so wanted this to go on like my fantasies, but I knew in my heart it wouldn’t. Again she took of her glasses and let her hair down, but this time also removed her cardigan to expose her delicate and feminine arms.
“Listen, I’m going to show you a way to destress,” Mrs Smith said whilst standing and moving away from her desk to face me. “Stand up,” she said softly, and I did as I was told. No hiding my boner now then, but strangely no kind of reaction from her either.
“Okay, I want you to follow my movements,” she spoke in a way that conveyed a seriousness about her care for my wellbeing. She tilted back her head and raised her arms above it and I did the same, only I couldn’t help but lean forward to catch a glimpse at her top rise out of her shirt, exposing her midriff.
“Hey! I said follow my movements,” she harshly exclaimed at me. With that I leaned my head back, her complete dominance in this situation only fuelling my need to release.
“Now breathe with me,” she commanded. I watched as she breathed deep breaths with the movement of her arms, entranced by her body moving in ways I had never seen before. She made one final stretch, higher than before, and with it let out a gasp of air that made me leak out of my boxers. A small wet patch permeated through my trousers, which Mrs Smith giggled at upon noticing. She was certainly relaxed.
“Come back next week and we’ll work on relaxing your muscles,” she said as she sank back into her chair, her breasts heaving up and down with her new pattern of breathing.
I spent the subsequent week confused. She certainly noticed my erection and pre-cum, but maybe after school hours she just feels more relaxed it could be nothing to do with attraction. Again I pumped load after load out of my cock daily, just imagining where things could have gone.
The next week came around. Time to ‘relax my muscles’, as Mrs Smith put it. This time I didn’t care about my boner as I walked to the front of the class and took the same seat as the week previous. As I sat at the chair, Mrs Smith began to again let her hair loose and take of her glasses. This hadn’t lost its sex appeal for me, so you can’t imagine the blood rush to my cock as she began to unbutton her shirt. Fuck. At first I thought she would stop at a button or two, but no. She continued down her body, down her perfect tits and slight
stomach chub that I loved so much before each button was undone. But still she kept her shirt pulled across her, before catching my eyes which were firmly focused on her tits and saying, “I’m sorry, how rude, you don’t mind if I change into something a little more comfortable do you?”
I feverishly shook my flushed-red face back and forth as she let her shirt slide down her delicate body. She turned away from me and reached into a bag on the ground, slowly bending over. As she did this her skirt lifted slightly, revealing pink panties with the shape of her pussy imprinted into them. Underneath the fabric, there was a thick layer of liquid seeping through. I knew it for certain now, she was getting off on this.
As she turned back round to face me, she pulled a grey sleeveless top down, much to my sadness covering her tits enclosed in their matching pink bra back over. But she didn’t do too good a job, her nipples still protruded through, unmasking her underlying desires.
“As you know, I’m a woman of science,” she stated whilst getting me to stand off of my chair with a finger under my chin. “And so the body has always been of much interest to me. It’s connection to the mind.” As she said this she slid off my blazer and pulled my shirt from where it was tucked into my trousers, before removing my tie and unbuttoning my shirt. I’d never felt these sensations in my body before. Such desire. Such need to be inside another human being.
She continued, “I’m going to test my theory today. About stress being the true cause of your academic problems.” As she said this she got down onto her knees and undid my belt and my trousers, pulling them down to my ankles, revealing the precum seeping out of my boxers.
“Fuck,” I whispered under my breath, all that my mind could conjure in that moment. “Language, young man,” she replied playfully, a smile now falling upon her full lips whilst in eyeline of my cock. She reached a finger under my waistband and slowly rose back up, her 5’10 frame seeming to tower over me despite my four inches on her.
She turned and walked back to her desk, unzipping her skirt from the back and letting it fall as she did so. As it fell it revealed the fullness of her body. Her pink lace panties were consumed by her ass. It’s size and shape being something that I could only ever imagined I would see in person. Her legs were long, extending into soft, perfect thighs. All I wanted to do was go up behind her, bend her over her desk and take her. Make her feel what she does to me. How hard she makes my cock, how her body destroys my mind. But I was frozen.
Again she bent down into her bag on the floor, and now I could see the wet spot truly had grown. She was leaking juices, and she knew I could see it. She knew how badly I wanted to feel the warmth of her pussy on my cock. How I wanted to fondle her breasts and suck on her delicate neck. She displayed this knowledge with a sky smile as she rose and turned to face me. She was holding her cardigan in one hand and a bottle of moisturiser in the other. What was she going to do to me.
“Lay down,” she whispered into my ear as she draped her cardigan over the desk. I obliged as she told me, “You’re still so pent up, let me help you.”
With me lain on the desk, my erection climbing skyward, Mrs Smith leaned over from my head. With her hands enveloped in a thin layer of moisturiser, she laced her fingers in between mine before running them up my arms to my neck. All the while her huge boobs
were over me, giving me a clear view down her top. I squirmed as she traced the topography of my neck with her soft and delicate hands. She giggled before running her pointer finger over my lips. I took it in my mouth and began to suck on it, my mind looking for anything to numb my desire for my lips to be on her body.
She pulled it out and smiled at me before gently kissing my forehead, an action which would cause more cum to leak from my dick. She noticed this, her gaze drawn to it. She slowly and tantalisingly walked down the length of the desk, running her fingers down my stomach to my thighs. She began to massage my thighs, leaning over my legs giving me a full view of her cleavage. As she massaged, her fingers rose and rose before penetrating the bottom of my boxers. I gasped and squirmed, my knuckles white from gripping the desk. Again she let out a small laugh before letting saliva drip one long, teasing drop onto my thighs. This was her moisturiser now, as she travelled further and further up my boxers. Her fingers played with my short, trimmed pubes; danced elegantly around the base of my shaft.
“I’m not going to let you cum, you know,” she said, climbing onto the desk. She drew herself further and further up my body, dragging herself over my boxers leaving a trail of precum down her body.
I shook my head. All words had left me all I could think about was cumming. “Please… please…” I whimpered desperately. She was now kneeling on top of my dick in some kind of clothed cowgirl facsimile. She raised herself up, still on her knees, and slowly pulled down her panties. A trail of her own precum came with it, stretching from her pussy to the underside of her panties. “But I do have a gift for you,” she said. She climbed down from the table and slid off my boxers. I was gripping the table, the tip of my cock in a pool of precum. She covered her mouth with her hand and let out a small laugh, staring at my pulsating cock. Then she turned her gaze so she was making complete eye contact with me, before wiping the cum from my cock with her panties. Her soaked pink panties were now covered in fresh thick cum. She touched me so delicately, fuck she really didn’t want me to cum. Why?
“These are for you,” she whispered into my ear, lifting her hands of my cock just before I could cum. I was sweating profusely and so was she. She softly licked the tops of my ears before gliding away, pussy fully exposed. She bent down one final time for that day, this time exposing to me her perfect pink pussy. “I say they’re for you,” she said, continuing what I thought was an already finished conversation. “But I’m going to finger my pussy every day thinking of you cumming in my panties.” With that she walked over to me and kissed my forehead, guiding me off the desk to retrieve her cardigan. She left as I stood in a daze, before picking her panties off of my cock and cumming harder than I ever had before.
The rest of the week I was in a trance, a daily cycle of a full day of classes just waiting until I could go home and soak Mrs Smith’s panties with my cum. Sometimes I couldn’t wait. I had to start bringing them to school after a couple of days so I could cum in the bathroom. I would see Mrs Smith and get uncontrollably hard, I’d see her talking with an attractive girl and not be able to continue my day until I came to the thought of their sweat-covered scissoring. But Mrs Smith didn’t seem to feel the same. She wouldn’t so much look at me as I passed her, not to even think about eye contact. She didn’t start being a tease, and
remained as covered-up as ever. Maybe she thought she’d made a mistake, couldn’t stomach looking at me. It killed me waiting for our next session.
After another gruelling week came another one-on-one session with Mrs Smith. Again, I walked to the front of the class, and again she removed her glasses and hair tie. Only this time she didn’t stop there. “I really don’t know how to get through to you,” she said, unbuttoning her top. “I thought we’d released the tension.” Her shirt slid down her shoulders, leaving her breasts on show – this time in a lacy blue bra. Her stomach looked soft, a perfect place to release a load. As she unhooked her bra she said, “first I teased you, thought maybe if you had something to cum to you’d be less tense.” Her bra fell to the floor. Her nipples were small but hard, surrounded by a small pink areola. “Then I massaged you, relaxed your muscles,” she unzipped her grey teachers skirt, still facing me, revealing her pussy through her translucent panties. “Then I gave you even more wank material… give them here.” I reached into my bag and handed her the cum-encrusted panties, “and still you seem so tense!”
Now she began to undress me. She took of my blazer and tie, before putting the tie on herself over her almost bare chest. “But I think I have it figured out,” she whispered, biting her lip whilst undoing my belt. “You haven’t been fucking!” Her monologue was shocking me, I felt trapped by primal urges to cum inside her flooding my brain. “Take your eyes of my tits and look me in the eyes,” she commanded. As I did this her fingers teased my cock, this time reaching down into my underwear whilst the other hand pulled them down. I collapsed into her body, by face buried in her shoulder as she played with my cock with one hand and my hair with the other. “You broke up with your girlfriend, cumming into my panties is nothing like cumming inside a real pussy.”
And with that she put both her hands behind my head, grabbing at handfuls of my hair and kissed me. She made sure I could taste her spit as she pushed her tongue into my mouth. She explored every last crevice of it. Our tongues fought and danced in harmony with each other, only interrupted by occasional breaks for eye contact with a bridge of our combined saliva across each other’s mouths. Our sweaty bodies could not be any closer. I grinded my cock on the underside of her panties, before she slipped it out to grind on my thigh.
Again we broke away from each other’s kisses, but this time she began to run her tongue down the front of my neck. She kissed down my body as she got down on her knees. But still she had to tease me. She looked up at me and smiled, her makeup beginning to run ever so slightly. But she didn’t take my cock in her mouth. No, she kissed along the shaft. In her brain she mapped every kiss with the most reaction, with the knowledge that she would return there later. Then she swallowed it. She took every last inch down her throat, gagging slightly as it twitched and pulsated. She then began a rhythmic thrusting of her mouth up and down the length of my shaft, matching the rhythm with her fingers inside her pussy. As her moans grew her lips tightened around me. She was shaking from the force of her self- pleasure, overstimulated by the cock in her throat and the fingers in her pussy.
“Fuck… Fuck. Fuck.” I gasped, feeling the cum swell ready to explode down my teacher’s throat. But she knew that. Mrs Smith pulled away and stood up, gasping for air as she did so. Now I got a real look at her face. Her makeup was ruined, mascara streamed down her
eyes and a mixture of precum and drool surrounded her lips. “Please, please,” I begged her for release in between circling her nipples with my tongue. Instead of an answer she pushed her fingers into my mouth so I could taste her, before licking them clean herself.
“I’ll let you cum this time,” she said whilst kissing my neck, “But I have need too.”
She reached down to fondle my balls, “This cum isn’t going anywhere except my pussy.”
I couldn’t take it anymore. I strode over to her desk and brushed away a pile of books and papers. Returning to Mrs Smith I kissed her, pushing her back until she was pressed up against her desk. I held her under her knees and lifted her onto it, her pussy spread and dripping. I kissed her over her panties whilst she played with my hair, holding onto it for dear life. Now it was my turn. I ran my fingers under her panties, kissing her pussy all the while. She was shaking now, moaning loudly in between quivers that shook her whole body.
I pulled her panties off and let my tongue work on her pussy. She squeezed my head with her thighs and threw her head back. “Fuck… fuck… good boy… right there – fuck!” My fingers join, massaging her g-spot whilst my tongue focused on the clit. “I’m gonna cum – fuck I’m gonna cum!”
With that I pulled away and began to fuck her. The warmth of her pussy was instantly almost too much. The contractions of her orgasming body gripped my cock as it thrusted in and out. My hands were on her knees pushing her legs apart, letting me hit all the places no one had for a long time. Soon she was ready to cum again. Her breath became short and sharp and she pulled my body into hers. “Fuck, fuck, fuck,” she screamed as she threw her head back. Her whole body was shaking and contracting. Pure bliss and ecstasy in an orgasm.
As she returned to reality, her sly slime returned to her lips. “Now its your turn,” she said, leaned into my ear. I felt her breath on my face as she lowered her mouth to nibble on my earlobe. “Fuck me, fuck me,” was all I could say as I thrusted harder than I ever had before. “Be a good boy and cum for me,” the words sent me over the edge. I pushed her so she was lying on the desk and bit down on her shoulder as cum shot deep into her pussy.
“Yes, yes,” she moaned as she lent back, enjoying the warm spurts inside her.
“That’s enough now,” Mrs Smith said, pushing me off of her. I slumped on the chair I was sitting on originally, a sweaty and destroyed mess. My teacher was still lying on the desk, legs spread. I watched her wet pussy as cum seeped out of it, dripping into her other hole too. As she stood, I saw the cum drip down her thighs. She was still wearing my tie. Seductively, she walked over to where I was sitting and sat on my lap. Leaning over she whispered into my ear, “If you’re ever feeling tense again you know where to find me.” And with a kiss on the forehead, she was back to getting dressed again.
