Viviane opened his shirt, one button at a time, slow and teasing. Her lips trailing down his chest, kissing, licking, nibbling at the dips between his abs.
He flinched when her teeth scraped him. She almost bit, just enough to make him twitch.
Seamus grabbed her waist, fingers digging into her skin. "Calm down, Viviane. I'm not going anywhere."
She smirked, all hunger and fire. "Mmh… I love it when you say my name like that. Viviane." She whispered it like a prayer.
"It sounds so crisp, so fucking hot in your voice, like you're commanding me."
She giggled, hand sliding down his chest, brushing just above his groin. A faint trail of hair led her down, and she stopped right at the edge.
"I wonder if your junior agrees with me."
She bit her lip, slowly stripping off her dress. Behind that simple dress was her beautiful curved body, no bra, no shame.
Her breasts were perky, nipples already hard like they were begging for his mouth. She looked him dead in the eye, full of lust.
"I'm not wearing anything tonight behind my dress. Not when it's my first time fucking my stepbrother."
Seamus's throat bobbed as he swallowed hard. Their thing had only been going for a month, but it was already twisted, emotionally fucked and physically addicting.
They'd lost count of how many times they'd had sex, but somehow, every time it got nastier and hotter. She always knew how to rile him up, how to make him need her.
It was fucked up. But god, they both liked it that way.
"Hah… nothing at all?" His eyes trailed down her body, then locked on her soaked pussy. "You really are a slut for your stepbrother, huh?"
"Say it louder," Viviane laughed, wild and shameless. "You know the answer."
Seamus moved fast, his hands grabbing those perfect tits, twisting her pink nipples until her back arched and she gasped.
"Mmh~ You're impatient too, aren't you, brother?" she grinned, rubbing the bulge in his pants.
He was already rock hard, twitching under her touch. "I am," he growled. "So let's fucking start."
Viviane dropped down, her hands tugging at his pants and underwear. The moment it was all gone, his cock sprang free, thick, veiny, dripping at the tip.
She stared like she hadn't just sucked him off yesterday. Like it was new, like she craved it again.
"Come on, Sister, show me your skill."
Viviane grinned, she licked along the shaft, slow and filthy, letting her spit coat it from top to base. He groaned, head falling back, the way she tasted him like he was dessert.
"Shit… you're wetting it nice, huh?"
Viviane didn't answer. She held his shaft with one hand, slowly stroking the base while her mouth worked the top.
Her tongue swirled over the tip again and again, flicking that sensitive spot right under the crown, watching his stomach clench with every hit.
Then she took more, deeper this time. She gagged around it, tears pricking her eyes, but she didn't stop. Her lips stretched around his thickness, her throat clenching, spit dripping messily down the shaft.
Her eyes rolled back, like she was fucking addicted to it.
"Holy shit..."
Seamus murmured, her muscle throat was pulsating on his shaft like a pussy. It was wet, warm, and fucking good.
"Fuck," Seamus muttered, hand gripping her hair tighter now, the other clenched into the sheets. "You really want me to cum already?"
Viviane looked up at him without stopping, eyes glassy with heat, drool slipping past her lips as she bobbed her head.
Her spit was everywhere, stringing from her mouth to his cock, coating him in slick, messy wetness that only made him twitch harder in her grip.
She pulled off for a moment, panting, her lips red and swollen, a thin trail of saliva connecting them.
"Oh, I want you to last," she said with a grin, her voice rough with arousal. "But I love it when you lose control. I love watching you fall apart for me."
Then she sank back down, faster this time.
She pushed until the head hit the back of her throat, gagged, pulled back with a wet gasp, and went down again like she was chasing a high.
Her eyes fluttered. Her throat tightened around him. She wasn't just sucking him off, she was devouring him.
Seamus groaned louder, hips jerking forward before he could stop himself.
"Shit. Viviane!"
Her hand now moved in rhythm with her mouth, jerking the slick base while her lips stretched around the top half.
Her nose pressed into the soft skin of his abdomen again and again, and every time he flinched, she smiled around him.
"Hngghh~" she moaned, her pussy was dripping in heat right now, she wanted that fat dick so bad.
Seamus looked down and saw his now step sister like a bitch on her knees, tits pressed against his legs, spit drooling down her chin and onto his thighs, his cock stuffed in her throat and it nearly made him lose it right there.
"God, you're such a fucking mess…" he muttered, breathless.
"Hmm~" Viviane moaned around him in response, the vibration sending a jolt through his whole body.
She pulled back again, letting his cock fall from her lips, shiny with spit. She grinned, wiping her mouth with the back of her hand, eyes locked on his twitching shaft.
"You close, brother?"
"Yeah," he growled. "You're gonna make me cum if you keep going like that."
"Good," she said, grabbing him tight. "I want it."
She didn't wait. She took him back in, even deeper now, swallowing him whole like she needed it. Her hands held his thighs down as he instinctively tried to buck.
Her throat kept clenching, milking him with every motion. She wanted all of it, every drop.
Seamus groaned louder now, hand tangled in her hair, breathing ragged. "Fuck… I'm gonna cum!"
She moaned again, sucking harder, faster. That filthy slurp echoed in the room, wet and lewd and shameless.
He couldn't hold it anymore.
With a strained grunt, his body jerked and tensed, his cock throbbing hard as he came in her mouth, thick spurts shooting down her throat. She didn't flinch.
She swallowed every bit of it, moaning as he pulsed on her tongue, her eyes rolling slightly as if the taste was addictive. When he was done, she licked the tip once more, slow and teasing, then pulled away with a breathless laugh.
"Mmh… still the best flavor in the world."
She leaned up and kissed his lips, dragging some of that taste onto his tongue, slow and deep.
"How is it, blowjob by your sister?"
Seamus laughed, "Great, the greatest in the world?"
Both of them laughed for a while, controlling their breath to continue their next activity. The main course of the night.
