Chapter 6: Special Day For New Stepsiblings
Viviane straddled him right after swallowing him down, her body still flushed, her thighs sticky from her own juices.
She didn’t wait nor did she need permission. Her eyes were wild, pupils blown wide with lust as she lined herself up over his still-hard cock, the tip twitching and wet from her mouth.
Seamus was still catching his breath when she rubbed his tip against her folds, coating him in how wet she already was.
“Viviane, fuck, you’re really horny now, don’t you?” he rasped.
Never she been this excited before and it makes his heart beat fast. That girl always has a way to surprise him.
She chuckled low, teasing his cockhead against her entrance. “Stt, don’t call me by my name tonight, stepbrother. Call me sister, yeah?”
Seamus could only laugh and nod.
“And yeah, I’m really horny now, I was wet the second you said my name.”
Then, without warning, she slammed down on him. Her pussy perfectly hugged his thick cock as she moaned in pleasure.
“Ngghhh~ My stepbrother’s cock is amazing~”
Seamus choked out a hiss as her tight, hot cunt swallowed him whole. Her walls clamped around him, squeezing like velvet vice.
The sudden pressure made his hips jerk up, instinctively thrusting deeper, and she gasped, a sharp, needy sound that turned into a throaty laugh.
“Ohhh~ Fuck, you’re still so hard,” she hissed, rolling her hips slowly as she adjusted to his size. “I should milk you again. See how long you last.”
She started moving, grinding in a slow, tight circle, her hands on his chest for balance. Every shift made her walls flutter around him, dragging him deeper.
Her pussy was soaked, making every movement slick and noisy. It was messy, wet, raw, and perfect.
Seamus gritted his teeth, his hands flying to her hips. “You’re insane, sister,” he groaned. “You just made me cum, and now you’re riding me like you want another one?”
Viviane leaned forward, her tits brushing his face as she whispered, “I want three.”
Then she started to ride him properly, bouncing on his cock, up and down, fast and hungry. Every thrust made her moan, made her thighs slap against his hips, her hands gripping his shoulders for leverage.
“AHHH~ BROTHERR~ YOUR COCK TWITCHING INSIDE MEEHHH~”
Viviane’s moan started to be higher, as her movement became faster. His cock hitting her perfect spot, making her shudder in need.
“Damn, Sister ... Your pussy ... Is trying to kill me, huh?” Seamus groaned, half jokingly as his eyes started to unfocus becasue of the pleasure.
The way she moved, frantic and unhinged was almost too much. She wasn’t trying to be pretty about it. She was trying to break him.
“OHH!!! NGGHHH~ I’M BROTHER! I WILL DESTROY YOUU!!!” She tilted her head.
Seamus watched her through half-lidded eyes, her tits bouncing with every thrust, her hair clinging to her sweaty skin. Her lips were parted, breath ragged, eyes locked on his like she wanted to swallow him whole.
“Ahhh, Viviane-”
She cut him off with a kiss, wet, deep, tongue curling into his mouth as she slammed down on him harder. He could feel how close she was, the way her pussy clenched tighter with every grind.
“Ngghh~ You feel that?” she gasped between kisses. “That’s me about to cum on your cock.”
He could only groan in response, hips bucking up into her like his body had taken over.
