Something Amanda's never done before.

Amanda's breath caught in her throat as she felt his hardening cock press against her stomach. She knew she should say no, push him away, but her body craved his touch, yearned for more of what he could give her. "Seth, I..." she began, but her words faltered as he claimed her mouth in a searing kiss, his tongue demanding entrance as his hands roamed her curves possessively. Seth's kiss was hungry and demanding, his tongue delving deep into Amanda's mouth as he pinned her against the wall with his body. She could feel his arousal growing against her, hard and insistent, and it sent a fresh wave of desire pulsing through her veins.

When he finally broke the kiss, they were both breathing hard, their chests heaving against each other. "You're mine now, Mrs. Reynolds," Seth growled, his voice rough with lust. "I'm going to fuck you in every room of this house until you can't walk straight."

Amanda gasped, a thrill of excitement and fear covsing through her at his words. "Seth, we can't..." Seth silenced her with another kiss, this one even more possessive and demanding than the last. His hands roamed her body, leaving trails of fire in their wake as he kneaded and caressed her curves. "We can, and we will," he murmured against her lips. "You've wanted this for so long, haven't you? To be taken, to be used, to be fucked like the slutty MILF you really are?"

Amanda whimpered, her arousal surging at his crude words. She knew she should be offended, should push him away, but instead she found herself nodding weakly. "Yes." As the word left Amanda's lips, Seth wasted no time in claiming her once more, his mouth crashing against hers in a bruising kiss. His hands roamed her body greedily, squeezing and kneading her curves as he backed her towards the living room. Amanda stumbled along, her head spinning with lust and a growing sense of trepidation. This was moving so fast, but she couldn't seem to find the will to stop it.

As they reached the living room, Seth broke the kiss and spun Amanda around, bending her over the arm of the couch. She gasped as he gripped her hips, his hungry gaze raking over her bare bottom. "Look at this ass," he growled, giving it a sharp smack that made her yelp. "It was made to be spanked, to be reddened with my handprints." He punctuated his words with another smack, then another, until Amanda's cheeks were flushed and tingling.

"Please, Seth," she whimpered, writhing beneath him. He chuckled darkly, rubbing the heat into her skin. "Please what, baby? Please stop, or please don't stop?" His fingers traced along the curve of her bottom, dipping teasingly between her legs. "You're already so wet for me, aren't you? So needy." Amanda bit her lip, torn between shame and arousal as she felt his fingers exploring her.

"You want this, don't you?" Seth's voice was a low growl as he positioned himself behind her. "You want to be a dirty little slut for me, taking my cock in this tight ass of yours." Amanda's heart pounded as she felt the tip of him pressing against her entrance, slick with her own arousal. Seth leaned forward, pressing his chest against Amanda's back as he nuzzled into her neck. "I'm going to fuck this ass," he murmured, his voice a low, dominant purr. "I'm going to claim you, make you mine in every way possible."

Amanda shuddered, a mix of fear and excitement coursing through her veins. She knew this was wrong, that she should put a stop to it, but her body betrayed her, aching for his touch. "Seth, I... I've never..." she trailed off, her voice breathy and uncertain.

He cut her off with a nip to her earlobe, his hands gripping her hips hard enough to bruise. Seth chuckled, low and dark, as he rubbed the tip of his cock against Amanda's tight hole. "I know, baby. I'll be gentle, at first." He punctuated his words with a teasing push of his hips, the head of his cock popping inside her. Amanda cried out, her back arching as she felt the unfamiliar intrusion.

"That's it," Seth murmured, holding her hips steady as he slowly pushed deeper. "Relax for me, baby. Let me in." He rocked his hips in shallow thrusts, allowing her to adjust to his size. Amanda panted, her fingers scrabbling against the couch cushions as she tried to process the overwhelming sensations.

"Oh god." Seth growled in approval as he felt Amanda's tight muscles gradually relax, allowing him to slide in deeper. He ran his hands soothingly up and down her back, speaking in a low, husky voice. "You're doing so well, baby. You feel so good wrapped around my cock."

Amanda whimpered, overwhelmed by the intense feeling of fullness as Seth slowly pushed deeper, stretching her to her limits. Her fingers clenched the couch cushions, knuckles white as she tried to adjust to the unfamiliar intrusion.

Seth leaned forward, pressing his muscular chest against Amanda's back as he slowly thrust, savoring the tight heat of her ass. "You're mine now, Amanda. All mine." His hips began to move with more purpose, the sound of flesh slapping against flesh echoing in the quiet room. Amanda moaned loudly, the combination of pain and pleasure building inside her as Seth's cock stretched her in ways she'd never experienced before.

"Yes, Seth, yes!" Amanda panted, her head thrown back as she felt his hands grip her hips, pulling her back onto his cock. The intense feeling of fullness, combined with the raw animalistic nature of their coupling, pushed her towards the edge. Seth grunted, his thrusts growing more forceful as he felt Amanda's muscles clench around him. "That's it, baby. Take it all." He reached around, his fingers finding her clit and rubbing it in tight circles. Amanda's cries became louder, more **** as the dual stimulation pushed her higher and higher.

"I'm close, Seth! Don't stop!" Amanda panted, her body trembling on the edge of release. Seth growled in approval, his fingers working her clit faster as he pounded into her ass. The sound of skin slapping against skin filled the room, punctuated by Amanda's moans and Seth's grunts.

"Come for me, Amanda." Seth's commanding words pushed Amanda over the precipice. Her body convulsed as a powerful orgasm ripped through her, her inner muscles clamping down on Seth's thrusting cock. The intense pleasure bordered on pain as he continued to plunge into her tight, spasming hole.

"Yes, yes, YES!" Amanda screamed, her hands fisting in the cushions as wave after wave of ecstasy crashed over her. Seth's relentless thrusts and fingers on her clit prolonged her climax, each movement sending jolts of electric pleasure through her body.

Amanda's asshole clenched rhythmically around Seth's pistoning cock, the velvety walls rippling along his shaft. Seth's control finally snapped at Amanda's wanton cries. With a hoarse shout, he slammed into her one last time, burying himself to the hilt in her spasming ass. His cock jerked and pulsed as he spilled his hot seed deep inside her, marking her as his. The feeling of his cum flooding her most intimate place triggered a second, smaller orgasm in Amanda, making her moan weakly.

As the aftershocks of their intense coupling subsided, Seth slumped over Amanda's back, both of them breathing heavily. His softening cock slipped out of her abused hole, a trickle of his thick semen leaking out. Amanda whimpered at the loss, feeling empty and used in the most delicious way. Seth rolled off of Amanda, sprawling out on the couch cushions. He reached over to stroke her sweat-slicked back as she lay face down, still shuddering from the **** of her orgasms. "God, that was incredible," he murmured, his voice rough with satisfaction. "I don't think I've ever come that hard before."

Amanda made a weak sound of agreement, her cheek pressed against the leather. She felt utterly spent, every muscle in her body loose and pliant. Seth's release inside her had been so primal, so claiming. The thought made a dark thrill shiver down her spine even as part of her recoiled in shock.

"What have I become?" Amanda remained sprawled across the couch, her body still tingling with the aftershocks of their intense coupling. Seth's words echoed in her mind - his raw assertion of ownership, his desire to make her his in every room of their shared space. A part of her recoiled in shock at the sheer depravity of it all, but another, darker part thrilled at the idea of being claimed so completely.

As she lay there, Amanda's thoughts drifted to Henry. Guilt pricked at her conscience as she imagined her husband's reaction to her infidelity. What would he think of this? Would he leave her? The thought sent a fresh wave of guilt through her even as she felt Seth's hand tightening possessively on her hip.

"Amanda," Seth's husky whisper broke the silence. "I want to make you mine in every room of this house. I want to mark you, claim you, in every possible way." His fingers traced idle patterns on her skin, a clear reminder of his dominance. "Tell me you want that too."
