**I debated whether this belonged in Mind Control or Incest/Taboo. Contains consensual but trance-like sex between father and 18+ step-daughter and her BFF, related to a musical mind-control element. Hope you enjoy. All feedback welcome.**

I grinned as I glanced in the rear view mirror at my teen step-daughter and her bestie. The girls were giggling, taking selfies in the back seat of the SUV, and bouncing with excitement as they sang along with the music blasting from the sound system. Base thumped as their favorite artist "Flyte Contrl" rapped lyrics I couldn't really make out, except for the chorus of "Pop pop it, Pop pop it, Pop pop it now girl!"
Traffic slowed to a crawl as we neared the stadium, brake lights flashing, horns honking, strobes and lasers from the concert venue lighting up the dark sky.
"Amanda honey? We're almost here..."
Amanda and her BFF Maddy squealed in delight. Their voices jumbled together as they babbled over each other.
"OMG I CANT BELIEVE IT Flyte Contrl is so fucking hot I can't believe it's here best birthday gift ever..." they rattled on.
Amanda didn't seem too upset her mother had come down with the flu leaving us with an extra ticket for her Best Friend Forever, Maddy. Luckily Maddy's 18th birthday fell only a week before Amanda's, so she barely made the concert's 18+ age requirement.
The girls lept from the SUV and stumbled together toward the stadium almost before I'd finished parking.
"Hey girls, wait up," I shouted. My always-dramatic step-daughter Amanda spun around, whipping her long straight blonde hair behind her in a flourish.
"Hurry up old man" she said with a teasing smile, hand on hip, tapping her foot impatiently. Maddy giggled and smirked, her long wavy chestnut hair blowing in the breeze.
"Seriously Bryan, thanks for bringing us," Amanda said as I caught up to them, reining in her excitement for a moment, standing on her tip toes and giving me a peck on the cheek.
"Yeah, thanks Bryan," Maddy agreed coyly, narrowing her eyes a bit at me, then leaning in for a quick hug. I couldn't help but register her full breasts on my chest as she did.
Amanda grabbed her hand and pulled her toward the venue, with Maddy locking eyes with me for a moment, before turning away with what I could've sworn was a quick wink.
My cock stirred just a bit as she walked forward arm-in-arm with my stepdaughter, Maddy's short flouncy white skirt swishing as she walked. It was hypnotic.
Taking a deep breath, I shook it off. I'd kept in shape for my age, but I had no grand illusions. Twenty years ago maybe, I thought, shaking my head wistfully and smiling.
Throngs of fans pressed in on us as we neared the entrance.
"It's happening!" Amanda said with a grin, happily clapping her hands together with girlish excitement.
The three of us funneled along with the crowd into the stadium and were swept onto the dark turf near the stage, rushing forward to stake out a great spot standing just 30-40 feet away, hundreds of people swirling around us.
"These tickets are GREAT!" Maddy exclaimed, eyes wide.
The warm up act started moments later, and the pulse of the base hit my chest with a thump. The girls were taking selfies with their arms wrapped around each other, laughing, lights pulsing and coloring their faces and bodies with garish colors, red, blue, ultraviolet, purple, yellow and back again.
Amanda was bumped from behind and stumbled into me, nearly falling. I grabbed her under the arms catching her as she giggled and smiled up at me, eyes flashing. As she righted herself, her young firm breasts slid along my chest, pressing into me. Her smile faltered a bit, and she looked me in the eye, serious for a moment.
"Thank you Daddy," she murmured in my ear, kissing my cheek.
I was stunned. In the three years since I'd married her mom, she had never called me "Daddy" or even "Dad" before, only "Bryan".
"You're welcome sweetheart, happy birthday," I breathed into her ear as we were both jostled into one other by the crowd, our bodies bumping together in a very distracting way.
She lingered against me a moment longer, before pulling back with a sly smile. She turned and rejoined Maddy, both bouncing to the beat.
My head was starting to spin as the music thumped and the density of the crowd around us steadily increased, slowly pressing us toward the stage. Lights flashed strange patterns. Odors of beer, perfume, grass, sweat and others mingled to form a heady scent.
Amanda leaned against Maddy and said something in her ear, causing her to look back over her shoulder toward me with an evil grin. Her eyes looked a bit glazed. This time she definitely winked, and they both giggled.
I was having a hard time focusing, the crowd, the strobing lights, the pounding bass, the heat of bodies pressing closer around us. Sweat trickled down my back beneath my t-shirt as it vibrated with sonic pressure waves of snare drum, base, and rhythmic vocals.
My eyes fell on Maddy's ass again, this time watching it twerk and shake in time to the beat, next to my step-daughter's full round butt also moving sinuously in her very tight jeans. My head full of cotton balls, my heart raced, mouth dry, cock starting to stir, quickly rising hard as a rock and straining against my boxers.
The muscles of Maddy's toned calves flexed and relaxed as she bounced to the beat, and her tan thighs jiggled just the right amount. She twerked as the beat dropped and her skirt flipped up for a quick flash of her taut ass and the white thong panties she wore.
My head buzzed and my vision clouded, heart still thudding in my chest. Time seemed to start and stop jerkily, images flashed as more people pressed in around us. A sheen of sweat clung to my skin, and I shivered.
Just then darkness suddenly enveloped us all, and the brief absence of sound was deafening. Cheers went up from the crowd turning to wild howls and screams, someone whistled near my ear, then rose a chant of "Flyte Contrl! Flyte Contrl! Flyte Contrl!"
As a low base note slowly rose in volume, the electrified crowd surged forward suddenly and violently, and I stumbled forward into Maddy, my body pressed firmly into hers from behind. The sweet smell of her long brown hair filled my nostrils as I tried to brace myself with my hands on her shoulders.
A thunderous base beat dropped and the crowd reacted explosively, dazzling laser lights bursting to life.
My rock hard cock pressed fully into Maddy's back and buttocks as she gyrated against me. But rather than embarrassment I felt a strong shock of desire jolt through me as our bodies moved against each other, the friction of her supple ass cheeks stroking my rock hard member through the thin fabric of her loose skirt and my shorts.
Jostled again from behind, my right hand slipped from her shoulder and landed on her hip just above the soft swell of her ass, which seemed to send her body into overdrive. My cock slipped perfectly into the crevasse of her young peach-shaped butt, her skirt caught up out of the way, slipping and sliding as she twerked.
"Holy shit," I panted, and Maddy looked back over her shoulder with lust-filled eyes and a wan smile. The scene was dissociative, dream-like, primal and immediate. Flesh swirled around us. Layers of percussion now formed a complicated rhythm, assaulting my senses, reconstructing reality.
Brain muddled, my hands moved of their volition and began fully exploring Maddy's tight teen body now, sliding down her sides and upward under her loose tank top. Her hands covered mine and feverishly pushed them further upward to cup her full firm breasts, covered only with the thin lacey material of her filmy bra, her rock-hard nipples beneath my fingers threatening to pierce the fabric.
"Ohgodyesss," she shuddered as I pinched and swirled her nipples while leaning forward and lavishing kisses onto the nape of her neck.
My blood boiled and my cock throbbed as the base beat thumped, the laser light show flashing and strobing to reveal snapshots of Maddy leaning back into me, the back of her head thrown back resting at the base of my neck, chestnut hair splayed over my shoulder and chest, lips parted, breathing ragged.
"I'm going to fuck you senseless," I grunted into her ear as I reached down for my zipper and freed the iron rod in my pants. It sprang out and instantly found a home in Maddy's thigh gap triangle, sliding against her thong, already soaked with desire.
