I slammed the front door harder than I meant to, the sound echoing through our sprawling modern mansion like a gunshot. College had been a nightmare today. That bitch Emily from my econ class had spread a vicious rumor after our one awkward hookup last month—claiming I was "bad at sex," that I finished too quick and didn't know what the hell I was doing. Whispers followed me all day, snickers in the halls. By the time I got home, I was fuming, my face hot with embarrassment.
Our family situation was already complicated enough. Dad had remarried two years ago to Sophia, a stunning 42-year-old brunette MILF with curves that could stop traffic—full natural tits, a thick ass that jiggled just right in her yoga pants, and piercing blue eyes framed by wavy long hair. She was the ultimate cougar fantasy, always lounging around the house in casual blouses or tight sweaters that hugged her body. Then there was my stepsister, Ava—22, a slim redhead with pale skin dotted in freckles, cute little tits, and a small, tight ass that she loved showing off in plaid skirts or thongs. She had that modelesque look, tall and skinny, with wavy red hair cascading down her back. We weren't blood-related, thank God, but living under the same roof had always sparked this forbidden tension—stolen glances, accidental brushes in the hallway.
I needed advice. Badly. Sophia had always been the "supportive" type—open about sex, encouraging us to explore. So I found her in the living room, sipping wine on the couch in a button-up blouse that strained against her chest and a short skirt.
"Mom... I mean, Sophia," I muttered, sinking into the armchair. "Can I talk to you about something?"
She arched a perfectly manicured brow, her blue eyes sparkling with concern. "Of course, Ethan. What's wrong, sweetie?"
I spilled it all—the rumor, how it was bullshit but spreading fast. "I just... I don't know how to prove her wrong. Or get better. A girl at school said I'm bad at... you know, sex."
Sophia set her glass down, a sly smile curling her full lips. The air between us thickened immediately, her perfume—something sweet and musky—wafting toward me. "Oh, honey. Rumors like that are cruel. But if you want help... real help... I could teach you a thing or two." Her voice dropped lower, husky. "Ava's been dealing with something similar, actually. A boy at her art school called her 'frigid' after a bad date. She's upstairs, upset. Maybe we can all... support each other."
My cock twitched at the implication. Support each other? Before I could respond, she stood, her hips swaying as she headed toward the kitchen. "Come on. Let's check on her."
I followed, my heart pounding. The kitchen was massive—marble counters, huge island in the center. Voices drifted from around the corner. Sophia motioned for me to stay quiet, but curiosity pulled me closer. I peeked around the doorway and froze.
There was Ava, barefoot on the cool tile floor, wearing a loose T-shirt that barely covered her thong-clad ass and a plaid schoolgirl skirt flipped up slightly. Her pale legs were spread as she leaned over the counter. And in front of her... the biggest fucking cucumber I'd ever seen, thick and veined, glistening with saliva.
Sophia stood behind her, one hand on Ava's slim waist, guiding her. "That's it, baby girl. Relax your throat. Take it deeper. Good girls know how to worship a cock properly."
Ava's wavy red hair bobbed as she slid her lips down the vegetable, her cheeks hollowing with suction. Wet, obscene slurping sounds filled the kitchen—the slick glide of her mouth, her soft moans vibrating around it. Her freckled face flushed pink, blue eyes watering slightly as she deepthroated it effortlessly, her small tits pressing against the counter. She didn't look like she needed help at all; fuck, she looked like a natural, tongue swirling around the tip, licking up and down the shaft with hungry enthusiasm.
The scent hit me—fresh cucumber mixed with Ava's arousal, a faint musky sweetness in the air. My pants tightened instantly, my cock throbbing hard against my zipper as I watched hidden in the doorway. Sophia's hand slipped under Ava's skirt, rubbing her thong slowly. "See? Feel how wet you get when you do it right. Boys love a slutty little mouth like yours."
Ava pulled off with a pop, strings of saliva connecting her lips to the cucumber. "Like this, Mom?" she purred, voice breathy, then licked the underside slowly, fondling the base like it was balls.
Sophia chuckled, low and throaty. "Perfect. But nothing beats the real thing."
That's when she spotted me. Her blue eyes locked on mine, a wicked grin spreading. "Ethan. Come in, sweetie. Since you're here... why don't we make this a family lesson?"
My face burned, but my dick was rock-hard. Ava turned, her freckled cheeks flushing deeper, but her eyes—those cute, teasing eyes—lit up with excitement. No shock, just hunger.
"I... uh..." I stammered, stepping in.
Sophia pulled me closer, her full tits brushing my arm, nipples hard through her blouse. The heat from her body was intoxicating. "That rumor? We'll fix it. Ava needs practice too. Let's start simple."
She pushed me against the counter, Ava dropping to her knees beside her. Both barefoot, both staring up at me with those supportive, obedient smiles. Sophia unzipped my pants slowly, the sound loud in the quiet kitchen. My cock sprang free, thick and veined, pre-cum already beading at the tip.
"Look at your stepbrother's big cock, Ava," Sophia murmured, wrapping her hand around it, stroking slowly. The sensation—her warm, soft palm—made me groan. "This is what a real man feels like."
Ava licked her lips, leaning in. They took turns at first—Sophia's experienced mouth sinking down, deepthroating me effortlessly, her throat constricting around my length while she hummed. Then Ava, eager and sloppy, her tongue lapping at my balls, sucking them gently into her mouth, licking with wet, fervent strokes. The dual assault was overwhelming: Sophia's full lips sliding up and down, Ava's freckled face nuzzling my sack, their hands fondling, teasing.
"Fuck... oh God," I gasped, hands tangling in their hair—Sophia's wavy brunette locks, Ava's red waves.
They teamed up for the double blowjob, both tongues swirling around my shaft, kissing each other over my cockhead, saliva dripping down. Ball licking, deep sucking, Ava gagging cutely as she tried to match Sophia's pornstar-level skill. In minutes, she was matching her—throat relaxed, eyes locked on mine, moaning like she loved it.
I came hard, ropes of cum shooting into Ava's waiting mouth first, then Sophia's. They swallowed greedily, cum dripping from their chins, sharing a messy kiss.
But Sophia wasn't done. "Good start. Now, bedroom. Time for the real lesson."
We moved upstairs, clothes shedding along the way—Sophia's blouse unbuttoned to reveal lace bra and natural tits, Ava's thong soaked.
In the master bedroom, soft lighting, massive bed. Sophia strapped on a thick dildo from her drawer—realistic, veined, huge. Ava bent over the bed doggystyle, skirt hiked, outie pussy trimmed and glistening, pale ass cheeks spread.
"Watch closely, Ethan," Sophia said, rubbing the strap-on against Ava's wet folds. The slick sounds—her fingering Ava first, massaging her clit—filled the room. Ava whimpered, pushing back.
Sophia thrust in slow at first, then harder, pounding Ava's tight pussy. "See how I angle it? Hit her G-spot like this." Ava screamed in pleasure, small tits bouncing, freckles standing out on her flushed skin as she came hard, squirting a little, body shaking.
"Harder, Mom! Fuck me harder!" Ava begged, supportive and slutty.
Sophia demonstrated missionary next, Ava's legs wrapped around her, then reverse cowgirl, Ava riding the strap-on while Sophia teased her clit.
My turn. Cock aching again, I took Sophia's place. First Ava—sliding into her soaked, medium-haired pussy, tight and hot. She felt incredible, walls clenching as I pounded her doggystyle, learning from Sophia's guidance. "Deeper, Ethan! Make your stepsister cum!"
I did—over and over, overstimulation making her squirt again, crying out.
Then Sophia. I fucked her missionary, her MILF pussy gripping me, tits bouncing as I thrust hard. Ava watched, masturbating, then joined—tit play, fingering Sophia while I railed her.
Threesome chaos: Me in Sophia cowgirl, Ava sitting on her face; then me in Ava reverse, Sophia strapping on again to tease.
We ended with both on their knees, my cum painting their faces and mouths—money shots they shared hungrily.
Panting, tangled in sheets, Sophia smiled. "Rumor debunked yet?"
Ava giggled, licking cum from her lips. "We should practice more... just to be sure."
My cock twitched. This was just the beginning.
