You try

(Thanks to Davidtheruss for the idea)

You bite your lips and clench your fists as though you could battle through the intensity of emotions, “Does that mean you’re going to stop having sex with your father?” You could hardly believe she’d ever consider it, but the words slipped out in a **** plea, naked and raw. There was a pause, just long enough to crush the flicker of hope you hadn't even allowed yourself to acknowledge. Her lips curled into a smirk, wicked and knowing.

Amy traces her finger teasingly around your hard cock head, and her words sliced through any remaining delusions. “I don’t think you actually want that!” She sounded so confident, so assured of her knowledge of you that the doubt crept into your mind like a festering wound, leaving you to wonder if maybe she was right, and you were wrong about yourself all along.

You winch in disgust as a thick glob of cum falls blatantly from her pussy and lands on your knee “YES I VERY MUCH WANT THAT!” The words were almost a scream, as if volume alone could make them more believable, more truthful, more something you could anchor yourself to.

Amy giggles and her laughter is light but piercing. “Your mind might want that, but I don’t think your body does.” Her hand moves with deliberate slowness as she wraps her fingers around your cock and strokes it twice, her touch firm but gentle. You shutter as she continues without care for your dismay, “Which one do you want me to listen to, your mind or your body.” You tried to cling to the belief that you were more than primal urges, but the feeling of her skin against yours blurred the lines of certainty and made it all nothing but a jumbled mess. You could feel the resolve you released into the air crumbling under the weight of her touch, just like she knew it would.

Her hand felt so good that all you could manage to get out was a single word, “Please!” It was not the word you meant to say; it was too needy, too susceptible, too exactly what she wanted to hear. You clawed at shreds of dignity and self-respect, attempted to regain ground, but every move she made was calculated to push you further into yourself, to make it impossible to think.

Amy leans in, her closeness almost too much to bear as you are **** to inhale the vivid scent of her father sex radiating off her. She whispers into your ear, her voice smooth and confident, “Ok if your dead set on this, how about we try making our child right here, right now. If your mind can win out, and make you not cum before I do, I’ll listen to it over your body, and I’ll make dad stop having sex with me.” Her words were a challenge, and the rules were rigged well enough that she knew it would take a everything you had for her to lose. To her, it was a game, and you were losing before it even began.

"And if I lose?" you ask, voice trembling as Amy positions herself over you, her dripping pussy just inches from your throbbing cock.

"Then I’ll listen to your body, and I’ll keep fucking Daddy to make your body happy," she purrs, lowering herself slightly so her wetness barely grazes your tip. "And you get to watch... or join..."

Your mind screams to push her away, to run, to maintain some shred of dignity. But your body betrays you as she slowly sinks down, enveloping you in her warm

“oh fu fu fuck.” you gasp, feeling her wetness – slick with her father's remnants – surrounding you completely.

"That's it, baby," she coos, beginning to rock her hips. "Doesn't this feel good? Feeling me all sloppy and stretched from Daddy's big cock?"

You try to think of anything else – baseball statistics, work problems, your grandmother – anything to delay the inevitable. But Amy knows exactly how to move, how to clench around you in ways she never has before.

Her hips arch upwards and her body moves with practiced ease, determined and wild as she meets your hips effortlessly. The wetness of her pussy is slick and swollen with arousal as she takes you in deeper and more fully with each motion, her abandonment complete as though she was lost in the ecstasy of it all. Her inner walls clench with perfect timing around your cock, hot and tight and overwhelming as she rolls her hips in rhythmic harmony with your plunges.

She moans softly and then louder as her body trembles and her pussy walls begin to flutter, feeling the tension crest and break as she gushes around you. Her eyes are locked on yours, wide and intent and perhaps even cruel as she lets you watch her roll the warmth of her pussy further onto your shaft. There was a knowing light in her eyes, knowing how meaningless your resistance was now that you were inside her. The warmth you felt inside her was unlike anything you'd imagined, creeping into every part of you until you almost forgot about the condition of her win. You know the warmth is coming from more than just her, certain you can still feel some of her father's cum in there, but still it feels better than you ever thought it could.

Your mind struggled to comprehend how you could be losing, even as your body surged with the pleasure of defeat. Maybe it was the way she was looking at you, knowing and superior. Or maybe it was because you haven’t fucked her in so long, and you have never fucked her so raw and exposed. You had never fucked her after watching her get fucked like never before. You had never fucked her with more than your pride on the line. And you had never fucked her so fresh from getting filled with another man's cum. Whatever it was, she had known it would feel this good, and that knowledge was part of it.

"I've learned so much from Daddy," she whispers, grinding her wet pussy down harder on to your lap. "I am so happy that he taught me so many things to please you."

She leans forward, pressing her breasts against your face. The scent of her sweat and her father's cologne mingles together, creating an intoxicating aroma that makes your head spin.

"Suck them," she commands, her voice leaving no room for defiance. Your lips part in a futile attempt to protest, but she swiftly smothers your words by forcing her nipple between them, her movement hasty and unyielding. You quickly taste something salty. You’ve tasted her nipples countless times, and they have never tasted this salty, and you gag as the realization crashes over you like a wave of disgust. This is the taste of Greg, the unmistakable tang of cum smeared deliberately across her skin. Claustrophobic and repulsed, you try to pull away from the suffocating closeness, but her grip on you tightens like a vise, holding you captive, her resolve as firm as her body pressing against yours

**** to escape, you twist your head, but she follows your movements with relentless precision, her determination a **** as heavy as her father’s essence now seeping into your mouth.

"Just like that," she praises, lost in her own ecstasy

Your tongue flicks against it involuntarily, trying to expel the unwelcome taste, and she moans in appreciation, only more encouraged by your attempted resistance. To her, your struggles were nothing more than a lover’s passionate response, which it certainly wasn’t, at least wasn’t form your mind, your body on the other hand was more than enjoying her pleasured reaction to it.

“That's it," she encourages, increasing her pace. "I've grown to love how Daddy's cock feels inside me, but yours has its charms too."

Her words should disgust you, but instead they send electric currents of pleasure down your spine. You're getting close – too close – and she knows it.

"You're not going to last, are you?" she taunts, her rhythm becoming more intense. "You love feeling me like this – freshly fucked by my own father."

You try to hold back, gripping her hips to slow her movements, but she's relentless. She grabs your hands and pins them above your head, taking complete control.

"I can feel you throbbing," she whispers against your ear. "Give in. You know you want to."
