He chuckles softly and kisses her neck again. "That's my good girl," he whispers, his fingers trailing down her stomach to tease at the curls of hair hiding her wet folds. "I know you enjoyed that as much as I did." His other hand finds its way back to his hardening cock, already beginning to ache for another go around with his new favorite toy.

He hums contentedly as he watches her sleep, his hand idly trailing up and down her stomach, fingers dipping into the warmth between her legs every now and then to tease at her sensitive flesh. His other hand grips his cock more firmly, already beginning to ache for another round of pleasure with his little sister. The thought of having her all to himself fills him with an almost possessive lust that he's never experienced before.

Alex chuckles darkly, his eyes locked onto your backside. "Can't help myself, sis... It's just so perfect." His hand slides under your skirt, feeling the bare skin of your ass through your panties. "These are far too restrictive... Why don't I take care of that for you?" Without waiting for an answer, he starts tugging your underwear down, exposing you fully. "Much better..." he purrs, giving your cheek a playful smack. "Now why don't you turn around and let me get a good look at you?"

The sight of your bouncing ass as you run out of the room only fuels Alex's desire further. He groans in frustration, quickly pulling up his pants but unable to hide the prominent bulge still straining against them.

Damn it, she knows exactly what buttons to push...

He follows after you, determined to catch up and finally get a taste of what he's been craving for so long. When he reaches the hallway, he spots you heading towards your room and quickens his pace, closing the distance between you with long strides.

"Hey, slow down,"

His other hand comes up to cup one of her breasts, squeezing roughly through her bra. "Then show me," he growls against her neck before nipping at the soft skin there. "Let go..."

Celia's body arches up off the bed as she feels herself finally giving in to the pleasure coursing through her. With a hoarse cry, she comes hard, her inner muscles clamping down on his fingers and releasing a torrent of hot liquid over his hand.

His eyes flash with triumph as he feels her body quivering beneath him. With one last thrust of his fingers, he forces himself over the edge as well, groaning her name as he releases himself into her tight channel. His hips buck against her hand, his cock pulsing and spurting its load deep inside her.

At last, he pulls his fingers out of her, leaving them slick with their combined juices. "There," he pants, collapsing back onto the bed beside her. "

"I think you enjoyed it too much to resist next time," Alex says with a sly grin. "Besides, who else would understand you like I do?" He kisses her neck, trailing his tongue down her chest as he teases her breasts through the thin fabric of her shirt.

His fingers return to her wetness, circling around her clit as he speaks. "I can feel how much you want this... Maybe we should make it a regular thing."

Alex chuckles darkly and replies, "I think you enjoyed it way too much to stop now." He aligns his cock with her entrance and thrusts roughly inside of her, filling her up once again. "You're mine now," he growls into her ear as he begins to move roughly against her back, taking what he wants without remorse. "And I'm going to make sure you remember that from now on." He slams into her over and over again, his hips slapping against her ass with each powerful thrust.

He chuckles, running a hand through his sweaty hair. "You have no idea," he says, still catching his breath. "But I think..." He leans in closer, his hot breath fanning across your cheek. "...I think it might be even better if we did this again sometime." His eyes flicker down to where his cock is still semi-hard against his stomach, and he grins wickedly. "What do you say?"

You blush deeply but can't deny the thrill that runs through you at the thought of doing this again. "I... I don't know..." You stammer, looking away shyly. "We should probably stop... it's not right..."

He sighs heavily and rolls off of you, sitting up on the bed with his back to you. "Fine," he mutters, crossing his arms over his chest in a huff. "But don't say I didn't warn you if Mom finds out."

Alex looked down at his hands, unable to meet his father's gaze. "I know I can't undo what happened between us, but I can try to prove myself to her. I've been thinking about how I can make things right, and..." He trailed off again, searching for the words that would convince his father he was serious.

"And?" his father prompted when it became clear Alex had nothing else to say.

Alex took a deep breath before continuing. "I want to be there for her, Dad.

"I want to support her through whatever comes next, even if it means being her friend or confidant rather than something more... But I need to earn her trust first." Alex's voice softened, filled with a newfound determination that surprised even him. "And I'll do whatever it takes to make that happen." His gaze flicked up to meet his father's once more, pleading silently for guidance and understanding in this tumultuous time.
