Skip to content I woke up to the familiar sight of my old bedroom, a place I never thought I’d return to after moving out post-graduation. I’d once landed a flashy job at an ad agency with good pay and a promising future. But the work dried up, layoffs hit, and before long I was unemployed and out of savings. With nowhere else to turn, I ended up back home.
It was humiliating, but Mom welcomed me with open arms. At twenty-six, I was the oldest sibling, and instead of setting an example I was back under her roof, while Maddie, nineteen, was still living here and studying.
When I went downstairs, Mom was already in the kitchen. She wore sheer black stockings that hugged her long legs, a silky blouse tucked into a fitted skirt, and her hair tied back neatly. At forty-six, she was tall, beautiful, and confident, with curves that made her hard to ignore. Her perfume was light and floral, her lips painted bold red, a hint of blush on her cheeks.
She turned with a wide smile, setting pancakes on the table. “Sleep well?”
“Deep enough,” I muttered, sliding into a chair. “Thanks.”
Mom sat across from me, chin propped on her folded arms, eyes glinting with something she wasn’t saying. “I have a surprise for you.”
I laughed weakly. “I could use one. Right now I feel like a failure. The only things making me happy are you and these pancakes.”
She leaned closer. “You remember Julia, don’t you? My best friend.”
I did. The thought of Julia made me pause. She was gorgeous, a natural auburn-haired woman with a body formed into the perfect hourglass. She was the president at USC, my sister’s university.
I frowned, unsure where this was going. “What has my little sister been up to?”
She almost spat out the juice, chuckling. “This is about you, not Maddie.”
“Okay… go on.”
“I talked to Julia, and she can offer you a teaching position.”
I stopped chewing. That was not what I expected. “Teaching?”
Mom’s smile widened. “Yes.”
“A job?”
“Yes, sweetie. A job.”
That sank in, warming me more than the pancakes. But doubts hit me almost immediately. “But I’ve never taught anything. What am I supposed to teach?”
“Marketing and advertising. That’s your field. That’s what you know best.”
I mulled it over. She wasn’t wrong. I had the experience, but teaching? That was another world entirely. After I lost my job, I often thought about college and high school, wondering how those days had flown by so quickly. Back then, life was simple: chasing girls, parties, and having fun. There was nothing to worry about, just tight skirts, wild nights, and freedom. God, I’d do anything to go back.
“So what do you think? Do you want to go back to college … this time as a professor?”
I hesitated but finally shrugged. “I don’t have a lot of choices. The job market is brutal, and I can’t let your friend down either.”
Mom beamed. “You won’t. And she mentioned something about how nice it is to have a good-looking professor around.”
“Professor,” I muttered, laughing under my breath. The word felt strange in my mouth. Then something hit me, and my smile dropped. “Wait. Maddie goes there … And she’s studying marketing too.”
The thought hadn’t even crossed my mind until now. My nineteen-year-old sister, Maddie, with her skimpy outfits and flirty attitude, always pushed the limits, as if she wanted people to look at her. That was going to be trouble.
“Surprise her,” Mom said with a knowing smile. “I’m sure she’ll appreciate it.”
Then we heard her door swing open from upstairs. My sister went down the stairs shortly after. Maddie came into the kitchen wearing ripped denim shorts so short that the white pockets hung below the frayed edges. Her flat stomach was completely exposed below a tight crop top that clung to her chest. It was obvious she wasn’t wearing a bra, her nipples pushed against the thin fabric as she moved. The clothes were just the icing on the cake. Maddie wasn’t an innocent girl anymore. Her beachy, wavy blonde hair framed an oval face that looked flawless, her skin glowing with the kind of youth and fertility that turned heads without her even trying. She wasn’t as tall as Mom or me, but she wasn’t short either, standing at that sweet spot where her subtle hourglass figure drew the eye and seemed made for a bikini. Time had flown faster than I realized. It felt like only yesterday she still had that wide-eyed, innocent look, and now she had become a full-on bombshell.
I swallowed hard as the heatwave struck me hard.
“Maddie,” Mom said, giving her a half-playful and half-serious look. “Can’t you dress properly when your brother is home?”
Maddie shrugged, grabbing an apple from the fruit bowl. “What? I went shopping yesterday and wanted to try out my new stuff.” She bit into the apple, juice glistening on her rosy lips as it trickled down her cleavage. Her breasts looked like perfect teardrops, not full and bouncy like our mother’s, but not mosquito bites either. They were somewhere there in-between. She aimed her blue, greyish eyes at me, a smile curving on her lips. “Morning, bro … How’s it like being back here?”
“Not bad,” I said curtly, trying hard not to let my eyes stray any lower.
Mom sighed, glancing at her watch. “I need to get to the office. Try to behave while I’m gone.” She kissed my cheek and gave Maddie a pointed look. “We’ll talk about appropriate attire later.”
“Sure, Mom,” Maddie said with an eye roll.
“Bye, kids.” Mom headed for the door, heels clicking against the floor.
The moment the door closed, Maddie dropped into the chair across from me, crossing her legs. I tried not to stare at how the movement made her shorts ride up even higher.
My sister had bloomed into something dangerously hot. The realization annoyed me, but I couldn’t deny it. Her blonde waves cascaded over her shoulders, framing a face that had shed its childish roundness for sharp, feminine angles. When did this happen? I was still in disbelief.
“So,” I said, brushing my lips. “Are you and Mom on good terms these days?”
Maddie snorted. “Hardly. We fight constantly. Last week, she lost it because I came home at three in the morning. The week before that, she freaked about my grades.” She gestured at her outfit. “And obviously she hates how I dress.”
“To be fair, what you’re wearing is a bit … provocative.”
“Whatever.” She leaned forward, her crop top gaping slightly, giving me a peek of her cleavage. I wasn’t sure whether it was intentional or not. “I’ll let you know a secret,” she said, lowering her voice. “On Monday, we have a new professor. I need to look good for him.”
Something cold settled in my stomach. I clearly knew who that new professor was. “Why?”
Maddie’s smile faded. “Because I’m failing his class before it even starts. My grades last semester were shit, and if I don’t pull something off, I’m screwed.” She leaned against the table, so I could see more of her cleavage and upper parts of her breasts, even the pink areolas and the peak of her nipples. “So I figure I’ll have to bribe him the only way I know how. Spread my legs and hope he’s the type who can be convinced.”
The words hit me like a punch to the gut as I realized what she was suggesting. “Have you… have you done this before?”
“No,” she said, shrugging like we were discussing the weather. “But I have to give it a shot, otherwise I won’t pass the class. Mom will kill me if I flunk out.” She straightened up, leaning back in her chair. “I’m going over to Riley and Ava’s tonight. You know, the titty twins? They’re pros at this stuff. Figure we can practice some seduction techniques, make it a sleepover.”
I stared at her as it slowly dawned on me. Monday, the new professor, and the job Mom had just offered me. The pieces clicked together with sickening clarity.
“Ethan? You look weird. You okay?”
I nodded slowly, but inside, panic was spreading through my chest like wildfire. On Monday, I’d be walking into that classroom, and my sister would be sitting there in one of her barely-there outfits, planning to seduce me without knowing who I was. The thought of those calculating blue eyes looking up at me, of her crossing her legs and leaning forward the way she just had, made blood flow south.
“Yeah,” I said. “I’m fine.”
But I wasn’t fine. I was in deep, deep trouble.
“Alright,” she said, rising to her feet and licking the apple juice from her fingers. “I’ll bounce, and by the way, it’s nice having you here again.”
Her last words made me smile, but deep inside, I had conflicted feelings of being here again.
*****
The week slipped by faster than I expected, and before I knew it, Monday had arrived. Mom was driving me to the university, insisting on introducing me to Julia herself. Once she parked, we made our way toward the administrative building.
We were shown into a corner office with big windows and neat stacks of folders. Julia Bennett, the president, stood as we entered. Tall, auburn-haired, she wore a tight blouse that meant business, though it did a fine job of keeping her assets under wraps. I hadn’t seen her in a couple of years. She would eat dinner with us now and then. I wasn’t sure if that was still a thing, judging by Maddie’s character. But even when I was in college, I had constant fantasies about Julia, Mom’s best friend and one of the sexiest middle-aged women I knew of. After a closer look, I realized they were dressed almost alike, and I couldn’t decide which chest strained harder against her blouse. Julia had gone a little heavier on the makeup than Mom, her full, plump lips painted the color of red wine, her lashes long and dark, making it impossible not to stare at her face. She had that sharp, attractive jawline paired with sun-kissed skin that was undeniably sexy. She smiled first at my mother, then at me.
They hugged so their tits were mashed. My jaw slightly dropped as it looked like a tit would pop out any second. They held the hug quite intimately, which made me wonder if they had any secrets of their own. “And the prodigal son. Ethan, look at you. It’s so nice to see you again, all grown, healthy and strong.”
“He’s quite handsome, isn’t he?” Mom said proudly while raking her fingers through my hair.
“He is,” Julia said, her eyes sweeping over me like a cougar.
“President Bennett,” I said, shaking her hand.
“Please, just Julia,” she said with a deep smile. “I’m still your mom’s friend.” She gestured to the chairs. “Sit. I’ve got fifteen minutes before my eight a.m. crisis, so let’s make you official.”
Mom sat beside me like a proud agent who’d landed a deal. Julia slid a slim folder across the desk. She went over everything with me, though it was hard to stay fully focused because of how sexy she looked. Mom must have noticed, because she reminded me more than once to pay attention. There was a lot to take in, but eventually I signed the contract and they handed me a set of keys. Just like that, I was officially a professor, about to face a room full of college students.
We shook hands again. As we stepped into the hall, Julia added, “Welcome aboard, Mr. Hale. Go fire up the projector and breathe.”
I hugged Mom goodbye, and she gave me a kiss on the cheek. “You got this.”
“I do,” I said, making her smile.
The classroom was unlocked, and I headed inside. The nostalgia hit me hard from when I’d been a student. I felt a shiver run down my spine as I looked around. Rows of fixed chairs, a lectern, and a whiteboard.
Time passed quickly and suddenly, the students were already waiting for me outside. Within ten minutes, they began drifting in one by one. First, a pair of guys in hoodies who clocked me and went, “Yo, is that the TA or the new professor?” Then two girls who peeked at my slides, whispering and giggling. A group of three slid into the middle row and opened laptops like shields.
I stood at the front and tried to look like I belonged here. So far, all good. I hadn’t broken yet, and I did better than I imagined.
More young adults, backpacks thumping down, and a smell of coffee, gum, and dryer sheets. My watch ticked three minutes to nine. And then Maddie walked in. She was mid-laugh with another girl, head tilted, long hair over one shoulder. She wore a mini skirt and a crop top, not as skimpy as I thought it would be. Her eyes slid to the front, landed on me, and the laugh died in her throat. Her mouth fell open. The shock on her face punched straight through my chest.
She didn’t move for a beat. The girl with her followed her stare and then looked between us, confused. Maddie recovered fast, too fast, closing her mouth and smoothing her hair like nothing had happened. But when she took a seat in the second row, directly in my line of sight, the corner of her mouth curled.
I felt my tongue stick to the roof of my mouth. I reached for the clicker like it was a lifeline and woke the screen, forcing my voice to work.
I started teaching, and it didn’t feel as unnatural as I thought it would. It went well, but Maddie was surprisingly quiet. And even her flirtatious friends wondered if she was alright. She kept giving me glances now and then that leaned more toward the seductive side.
I still remembered what she’d said, her words of bribing her professor kept echoing in my ears.
*****
When I got home, Mom was already in the kitchen preparing dinner. She asked how it went, and I told her it was fine, that I was just happy to have a job again. It didn’t take long for Maddie to come in too, and the first thing she did was plant herself in front of Mom, arms crossed.
“You didn’t think to warn me that my big brother was teaching at my university?” she said with a questionable smile.
Mom flicked a look at me and shrugged, going for plausible deniability. “I thought it would be a fun surprise.”
Maddie rolled her eyes and opened the fridge. “You know how many people asked if I was related to ‘the hot new lecturer’ before I’d even sat down?” She yanked a can of Sprite, cracked it, and slugged half before glancing at me. “Thanks for the heads up, Ethan.”
I felt my ears heat. “It was a last-minute thing. Mom only told me about this when I moved back here.”
She sat on the barstool next to me, propping her chin on her hand. “Well, you made an impression. Every girl in class was texting about you by the end of first period.”
“That’s not true,” I said, trying to play it cool.
Maddie looked at me with laser focus. “Please. Compared to the rest of the faculty, you’re like—” She fished for the right word, settling on, “a fantasy substitute teacher from a porn parody.”
Mom’s knife clattered against the cutting board. “Maddie, we’re about to eat.”
She grinned at me, conspiratorial. “Sorry. I know I’m not supposed to say that at the table.” She sipped her soda, eyes glittering.
Mom plated the roasted vegetables, then set out a bowl of salad. “Maddie, why don’t you help set the table?”
Maddie slid off the stool and started pulling plates from the cabinet. “So, are you going to fail me if I sleep through your class, or do siblings get a free pass?” she asked, setting the table.
“I’ll give you your grades, but no special treatment,” I said.
“Why not? Afraid of showing favoritism?” She wiggled her eyebrows at me and set the plates down, then leaned in close enough for me to smell the vanilla body spray.
Mom bristled. “He’s right. He can lose his job. Just study and don’t slack off, Maddie.”
Maddie crossed her eyes in mock exasperation. “I’m kidding. Jeez.”
Dinner turned a little heated. Maddie kept pressing for favors, while Mom rolled her eyes and answered her with that firm, no-nonsense tone she always used when Maddie pushed too far.
After dinner, and right when we were about to go to bed, Maddie knocked on my door.
“Yeah?” I said.
Maddie cracked the door and peeked in. Her hair was damp and darker near the ends. She wore a big T-shirt that slid off one shoulder and small shorts that barely counted, no bra, her nipples poking against her clothing. She stepped inside and closed the door behind her.
“I’m not staying,” she said. “I just wanted to say I’m not mad.”
“I did not think you were,” I said.
She came a step closer, and her voice dropped. “I was out of line. I know how to push buttons. I like it too much.”
“I noticed.”
She smiled at that. “Mom scares me when she gets that voice.”
“Me too,” I said before I could stop myself.
She laughed, then sobered. “I’ll be good.”
“Good would be good,” I said.
She looked at me for a few seconds like she was deciding whether to say something else. Then she tipped her head, almost shy. “Also, you were really good today. In class.”
The compliment landed right in my heart. It felt surprisingly warm and good. “Thanks.”
She slipped a hand into the pocket of her shorts and rocked on her heels. “Okay. Goodnight.”
“Goodnight,” I said.
She turned and opened the door, then paused and looked back over her shoulder with a spark in her eyes that had nothing to do with apologies. “Oh. One more thing. You should get ready.”
“For what?” I asked, even though I knew.
“For some serious college pussy,” she said playfully. Her mouth curved. “Professor.”
*****
I kept teaching, actually enjoying my new role as a professor, and before long the first test was right around the corner. While we were having a family dinner, Mom asked, “So, Maddie, how’s the studying going?”
“Fine,” Maddie said insecurely, twirling her fork.
Mom’s eyes narrowed. “Are you sure? You’ve been at the beach a lot. And I know you’ve been out with your friends.”
Maddie forced a smile. “I can multitask.”
Mom looked like she wanted to press more, but let it slide. My stomach knotted anyway as I feared she’d try to bribe me.
*****
The night before the test, I sat in my bedroom with a red pen, flipping through notes and half-graded assignments. I was exhausted, but I wanted my prep airtight.
A knock broke my focus.
“Yeah?” I called.
The door cracked, and Maddie slid in, wearing a transparent nightgown that showed off her teardrops. I immediately looked away.
She spun once playfully, her wavy blonde hair fluttering. “Be honest. Do you think this is cute?”
“What do you want?” I asked, sharper than I meant.
She sighed, flopping onto the edge of my bed. “I forgot about the test. I’ve been busy. I didn’t study.”
“That’s your problem,” I said, turning back to my papers. “Not mine.”
“You’re so cold,” she teased. Then her tone dipped. “I’ve been a bad girl. Maybe you can … help me?”
“Maddie—”
She stood, closing the space between us. Her fingers grazed my thigh. Then, boldly, her palm cupped me through my pants. My whole body stiffened.
“Maddie … I’m your brother. What the hell are you doing?”
“And?” she said playfully. “Are you scared of sibling love?”
“Maddie,” I hissed, grabbing her wrist. “Mom is home—”
A knock hit the door, and it was Mom. “Darlings, are you in there?”
Maddie leaned in so close her breasts made contact with my shoulders, and I felt her lips stiffening. “Next time you won’t escape.”
She pulled away and opened the door, smiling sweetly. “We’re here, Mom, just saying goodnight.”
Mom glanced past her, eyes flicking to me, to the obvious bulge I couldn’t hide fast enough. Suspicion flashed across her face, then she smiled politely and walked away.
Maddie blew me a kiss and slipped out, leaving me even more frustrated than earlier. A part of me really wanted to fuck her, but I was just so horny that I couldn’t think straight. It had been weeks of being surrounded by young women at the peak of their beauty and to be in the center of their attention. I wasn’t sure how long I could continue on like this, but I had to do my best.
*****
The test came fast. I stood at the front, proctoring, watching students scribble and sigh. Most finished early, handing in their papers with relieved smiles. The room thinned until only one person remained.
Maddie.
She chewed her pen, frowning at the page like she’d never seen the material before. Even the titty twins had finished before her. Finally, she stood and walked to me, dropping the paper on the desk.
“How’d it go?” I asked.
She sighed, leaning close. “Didn’t understand much.”
“You should’ve studied,” I said flatly.
Her lips curved. She leaned over the desk, hair falling like a curtain. Her whisper was heat against my skin. “Still think I don’t deserve a little extra credit?”
“No.”
“Come on … we’re siblings.”
“Maddie—”
Before I could react, she slid to her knees.
“What are you—”
Her fingers found my zipper. She tugged it down, bold and unstoppable.
“Someone could walk in,” I said, even though I really wanted this. It was exactly how it played out in the wet, forbidden dream, a memory I’d never forget. To have it happen in front of me was a dream come true, even if I clearly knew about the risks we were taking. If we got caught, it wouldn’t be pretty for either of us.
Maddie didn’t care. She released my erection, and she gave me a look as my length cast a thick shadow over her face. “You think I’m hot … otherwise you wouldn’t be this hard.”
“No, I don’t,” I lied through my teeth.
“Come on … You don’t have to lie to me.”
“Alright, you’re hot as fuck,” I told her truthfully. “But if we get caught—”
She didn’t care. She opened up her mouth and for the first time in our lives we crossed this line. She slid her strawberry-painted lips over my cock and glided it directly down to the back of her throat. She pushed me deep into her warm mouth, deeper than I thought possible. I felt my cock hit the back of her throat, and she didn’t even gag.
“Fuck, Maddie,” I whispered, my hands gripping the edge of the desk.
She kept me there, stuffed in her mouth with her lips stretched around my girth. I felt her entire mouth contract around my shaft like a sweet, oral massage.
She pulled back slowly, sliding my length over her tongue. When she reached the tip, she looked up at me with those blue-gray eyes, and I saw pure lust, love and adventure there. She kissed the spongy crown, never breaking contact. Then she opened up wide as if she were seeing the dentist, and she dove back down, taking me even deeper this time, her throat muscles contracting around me till her lips touched my root. She gagged a little, but she kept me there like a good girl.
It was taboo as hell. My sister, my student, on her knees in my classroom. Every rational part of my brain screamed that this was wrong, that we had to stop, but my body had other ideas. I couldn’t make myself push her away. She was just too damn good at this, a skill I didn’t even know she possessed.
She pulled her head back and resorted to rapidly bobbing her head up, focusing on the tip while her saliva coated every inch of me. The wet sounds filled the empty classroom, obscene and erotic, while spit pooled on the floor below us.
“Jeez, Maddie,” I said, smiling for the first time as she slowly brought me to heaven.
When she pulled off completely, a string of spit connected her lips to my cock.
“You taste so good, brother,” she said, stroking me with her soft right hand, then leaned forward to lick me from base to tip like I was her favorite lollipop. Her tongue was soft and warm, tracing every vein and ridge. It was exactly like in the dream, and I couldn’t stop myself from thrusting forward, making my hard-on slide past her cheek.
“Someone’s getting excited,” she said with a giggle, grabbing my cock and aiming it at her mouth again.
“Where did you learn to suck like that?”
“That’s a secret,” she said mischievously.
She plunged me back into her throat, and I watched in amazement as my cock disappeared completely into her mouth. She held me there for what felt like forever before slowly pulling back, gasping slightly when she came off with saliva all over my shaft and her lips. It was such a big mess it looked like I’d blown a load already.
Then she did something that nearly made my knees buckle. She gathered more saliva in her mouth and spat directly onto my cock, watching as it dripped down my shaft. She used her hand to spread it around, making me slick and shiny in a twisting motion.
“God, you’re such a dirty girl,” I groaned.
She grinned up at me, that same smile that had been driving me crazy for weeks. “Do you want to fuck my face?” she asked, her voice sweet and innocent despite the filthy words.
I should have said no. Should have pulled away, zipped up my pants, and pretended this never happened. Instead, I found myself nodding, my hands moving to cup the back of her head.
Her hair felt like silk between my fingers as I guided her mouth back onto my cock. This time, I controlled the pace, pushing deeper with each thrust. I could see the outline of my cock bulging in her throat, and the sight was so erotic I nearly came right then.
Maddie’s hands gripped my thighs as I thrust my hips right at her face, and she made these little humming sounds that vibrated through my entire length. Her eyes watered slightly, but she never pulled away, never gave any sign that she wanted me to stop.
I tightened my grip around her neck, keeping her pinned there as I slid my cock in and out of her sweet, precious mouth.
After a few minutes, she tapped my leg, and I released her head. She came off my cock with a gasp, strings of saliva connecting us.
I thought she’d complain for air, but instead, she said breathlessly, “My turn.”
I watched, mesmerized, as she placed her hands firmly behind her back. She looked up at me with a grin spread on her lips before she would plunge my cock back into her mouth.
“No hands,” she whispered, then opened her mouth and took me in again.
This time was different. Without her hands to guide or control the motion, she had to work entirely with her mouth and throat. She bobbed her head rapidly as if she could do that all day, tightening her lips around my cock. Her lipstick was already smudged around my entire erection, and the sensation of her warm, wet mouth constantly around me was incredible, more intense than anything I’d ever felt.
I gripped the edge of the desk harder as she sucked me with just her mouth. She varied her pace, sometimes slow and teasing, sometimes fast and desperate for cum. Her throat muscles contracted around me as she took me to the hilt, her nose pressed against my pelvis.
“Maddie,” I groaned, feeling that familiar tightness building in my core. “I’m going to come.”
She didn’t pull away. Instead, she looked up at me and somehow managed to nod while keeping me buried in her throat. That sight, those eyes looking up at me while her mouth was full of my cock, pushed me over the edge.
My orgasm hit me hard like a volcano waiting to erupt, and when I erupted, I came harder than I ever had in my life, my entire body convulsing as I fired spurt after spurt of cum down her throat. I was shaking as I tried to hold onto her head, afraid I’d collapse because of the intensity. I emptied myself thoroughly into her mouth, and for a moment I wondered if this was another dream, if I’d wake up in my bed with sticky sheets.
But I didn’t wake up. This was real.
Maddie held perfectly still as I came, taking everything I gave her. When I finally finished, she slowly pulled off my softening cock, keeping her mouth closed. She looked up at me and opened her lips slightly, showing me the pool of my cum on her tongue before closing her mouth and swallowing with an exaggerated gulp.
“Good girl,” I said, still trying to catch my breath.
She grinned and reached for the tissue box on my desk, pulling out several sheets. “That was so sloppy and messy,” she said with a laugh, gently cleaning my cock with the soft tissues. “I made such a mess of you.”
I watched her tender hands, still in shock that this had actually happened. My sister had just given me the best blowjob of my life, right here in my classroom.
“This can’t happen again,” I said hoarsely.
“Sure, Professor. Whatever you say.” Rising to her feet, she kissed me quickly and filthy, then leaned back. “Think you’ll return the favor? Wonder what kind of grade I’ll get.”
“That was a top performance,” I muttered. “Your grade will be top.”
She winked. “Thanks for the A.”
“And thanks for the head.”
