The scent of her perfume—something expensive and vanilla-sweet—hung in the air of Jasper’s room, mingling with the musky scent of sex. Sara was draped over his messy bed, a vision of disheveled perfection. Her signature blonde blowout was a golden halo against his dark sheets, though now it was slightly ruffled. Her makeup, which had been flawless an hour ago, was only a little smudged around her big, hunter-blue eyes.

Jasper lay beside her, catching his breath, his heart still hammering against his ribs. The evidence of their latest "study session" was cooling on his stomach and her thigh.

"You're getting lazy," Sara teased, her voice a husky murmur. She traced a finger through the mess on her skin, bringing it to her full, glossed lips with a wicked grin. "You used to be able to go twice before looking like a beached fish."

"Maybe my sister is just insatiable," he shot back, propping himself up on an elbow to look at her. The sight of her, naked and claiming his cum, sent a fresh, dull throb of desire through him. It was a power she wielded effortlessly.

She rolled onto her stomach, her well-trained ass highlighted in the afternoon light filtering through the blinds. "Insatiable, maybe. But also, you know I hate wasting it." Her eyes, those piercing blue eyes that could command a room or beg for more with a single glance, met his. "I like feeling it inside. Knowing it's taking."

The breeding kink. It was her favorite, the thing that made her moans escalate into desperate, echoing cries that he was sure the whole neighborhood could hear. It was the core of her weirdest, most intoxicating kink, and by extension, his own.

"It's not taking, Sara," he said, though the thought alone was thrilling. "We're not exactly prime candidates for parenthood."

She just smiled, a secret, knowing smile that didn't quite reach her eyes. "You never know. It's the risk that's fun." She shifted closer, her small breasts pressing against his arm. "Besides, it's in our blood, isn't it? This... appetite. Dad certainly thought so."

The mention of their father didn't bring the tension it might have in another family. Instead, it hung between them like a shared, forbidden language. It was the ghost in the room, the one that had shaped Sara into the woman she was and had given Jasper the key to a kingdom he never knew he wanted to rule.

Her hand slid down his stomach, her intent clear. "Come on, Jasper. One more time. For real this time. I want to scream so loud the pictures fall off the wall."

Their breath came in ragged gasps as they rolled over onto their sides, facing each other. Jasper's hard length pressed against her thigh, and she ran a hand up his stomach to cup his erection, guiding it toward her wet heat. Her fingers brushed against the head of his cock, and he let out a groan as she slowly sank down onto him inch by agonizing inch until he was fully seated inside her.

"Fuck,"

Her eyes widened, and then she smirked. "Oh, you mean the time I let him fuck me?" She laughed lightly, a little unsteady. "I was sixteen. He'd been drinking at some stupid charity event or something. We were home alone, and he came into my room... just drunk enough to start acting on it."

Her voice trailed off as she stared up at the ceiling, remembering the feel of his rough hands on her skin, the taste of alcohol in her mouth.

"I didn't want to tell you," she admitted quietly. "It was... strange. It felt wrong somehow. But then we started doing it more and more, and it just sort of became this thing between us." She shrugged, a little helpless. "I guess I got addicted to the attention or something."

Jasper's grip tightened on her hips as he began to thrust into her, their bodies slapping together in rough rhythm.

She giggled, the sound turning into a moan as he hit her sweet spot. "Yeah, something like that," she gasped, arching her back to meet his thrusts more deeply. Her fingers dug into his shoulders as she felt herself starting to lose control. "God, it's been so long since I've had someone else... It feels good to feel you inside."

Her hips bucked upward, her nails digging into his shoulders as she cried out in pleasure. "I love the way you feel inside me," she moaned. "Give it to me hard, Jasper." Her words were punctuated by another moan as he slammed into her, filling her up with each powerful thrust.

"Ahhhh!" She threw her head back, her eyes clenched shut as the pleasure consumed her.
