You tie

Just as you're about to lose control, she suddenly stiffens above you, her back arching dramatically as she cries out, "Oh fuck, I'm cumming!"

Her pussy contracts around you in powerful waves, and despite your best efforts, you explode inside her, filling her with your seed alongside her father's.

As you both catch your breath, she looks down at you with a triumphant smile.

"Looks like we came together," she says, her eyes gleaming with mischief. "Wow… Honey, I am impressed I didn’t think you could last that long!"

She leans down to kiss you deeply, her tongue invading your mouth without permission.

"Welcome to our new family arrangement," she whispers against your lips. "I think you're going to love it more than you realize" Before she takes your hand and pulls you to your feet “Now honey follow me?”

Confused you ask “Why… where are we going?”

She smiles at you “We are going to talk to my father, and then we are going to fuck him.”

You groan in pain “Wait I thought this meant you were not going to have sex with him anymore.”

She wiggles her ass towards you, as she looks over her shoulder “What I said was if you make me cum first, I would **** dad to stop. But what happened was we came together… If your mind held out one second longer, you it would have won, but it didn’t, and what happened was your body told me that it wanted me to feel the best, while keeping going. “She winks at you, before pulling you towards the living room.”

"Wait, Amy—" you protest weakly, your legs still trembling from your release as she drags you through the hallway. Your mind races with conflicting emotions—shame, exhaustion, and a disturbing undercurrent of anticipation that you can't quite suppress.

The walk to the living room feels like a **** march. Your shirt sticks to your chest, still damp with your earlier emissions, and see can see the mixture of fluids beginning to trickle down your wife’s thigh. The physical evidence of your surrender.

Greg sits sprawled on the couch, naked and unashamed, his impressive manhood resting against his thigh, as casually sipping a beer with a smile on his face as though he hadn't just been balls-deep in his daughter minutes ago.

"There's my girl," he says, eyes moving from Amy to you. "And there's the boy who just lost our little wager."

Amy pushes you onto the armchair across from her father, positioning herself between you both. "We came so hard together, Daddy." You watch as Greg face flashes with anger, you are unsure whether he is angry that you came inside his daughter or that you made her cum as his glare studies you. “So, son, are you finally coming to terms with our arrangement?”

Words fail you. What could you possibly say? That you hate this, but your body betrays you? That some dark part of you thrives on this humiliation?

"I'll take that silence as progress," Greg chuckles. "Amy, sweetheart, why don't you tell him about my plan?"

Amy perches on the arm of your chair, her naked body still glistening with sweat and fluids. She strokes your hair with unsettling tenderness.

"You see, baby, now that you've admitted with your body what your mind won't say, we can all live together properly." Her fingers trace your jawline. "Daddy's moving in permanently. The guest room will be his. Some nights I'll sleep there, and some nights with you."

Your stomach knots as the full implication hits you. "You can't be serious."

Greg ignores you as he wraps his arms around his daughter's body as if he is forming a shield against you “More like she will be spending most nights if not all nights.”

Amy turns away from you and looks her father in the eyes “Daddy, you said you wanted to move in to make sure we were both are the happiest we could be. My husband may be happy just listening.” She reaches down and starts stroking his cock “But I just learned I can’t be the happiest I can be if he is not involved at least soon times.”

Amy then turns back to you. "Isn't it wonderful? We're going to be one big happy family. And when I get pregnant, you'll never know for sure if it's your baby or your brother."

The room spins around you as their laughter mingles together. This is your life now—a twisted arrangement you never asked for but can't seem to escape. And the most terrifying part is the small voice inside you wondering if maybe, just maybe, some broken part of you might learn to accept it.

Your father-in-law runs his hands over her pussy as he laughs “Oh Amy, we certainly will know because know he is not man enough to ever stand a chance at that…” He gently wraps her hand from his cock before pointing right out her open womb “Now your worthless punk watch me breed my princess.”

Amy groans “Daddy."

Greg laughs “It's ok… Remember I told you he gets off on me calling him what he is.” as he winks at you.”

Amy whimpers "ok, Daddy, but I think we let him join us.”

Greg's eyes are narrow as he lifts Amy, his cock already hardening beneath her. "You think he deserves that privilege?"

"Please, Daddy," she begs, her voice taking on that childish tone that makes your skin crawl. "He might not deserve it, but I want it."

You want to look away but can't as Greg positions his massive shaft at Amy's entrance, still slick with the mixture of your fluids. With one powerful thrust, he impales her, making her cry out.

"Fuck, kiddo," he groans, bouncing her on his lap while maintaining eye contact with you. "Still so tight even after taking both of us."

Amy reaches her hand toward you. "Come here, baby. Touch me while Daddy fucks me."

Greg taunts you “Yeah boy, touch my princess while I do something you can’t even dream of doing.” causing you to remain frozen in the armchair.

"Don't make me beg," she whimpers, her body jerking with each of Greg's thrusts. "Just hold my hand at least."

Against your better judgment, you move closer, taking her outstretched hand. She immediately pulls you in, guiding your other hand to her breast.

"That's it," she moans. "Feel how excited Daddy makes me."

Greg watches with calculated intensity as you reluctantly caress your wife while he continues pounding into her. "Look at you, boy. Getting off on watching your father-in-law do what you can't."

Amy's orgasm builds quickly, her body shuddering between you both. "Kiss me," she demands, pulling your face to hers.

As your lips meet, Greg increases his pace, the sound of flesh slapping against flesh filling the room. Amy breaks the kiss to cry out, "I'm cumming again, Daddy!"

Greg's rhythm becomes erratic. "Me too, princess," he grunts, holding her firmly as he empties himself inside her.

You back away, disgusted yet still aroused, as Amy collapses against her father's chest. They share a deep kiss before she turns to you with a satisfied smile.

"See? We can all be happy together."

Greg whispers something in Amy's ear that makes her giggle. "I need to freshen up," she announces, standing on wobbly legs. "Don't you boys start fighting while I'm gone?"

The moment she disappears down the hallway, Greg's expression hardens. He stands, his imposing frame towering over you, still slick with your wife's juices.

"Listen carefully," he says in a low, dangerous voice. "I know I can't stop my little girl from fucking you anymore. Despite my best efforts, she's made her choice to keep you around. For the life of me, I’ll never know what she sees in trash like you.”

He steps closer, and you instinctively back up until you hit the wall.

"But understand this," he continues, jabbing a finger into your chest. "If your sperm takes hold in my princess's womb, they'll never find your body. That's a promise."

The cold calculation in his eyes leaves no doubt he means every word.

"I've got connections you couldn't imagine," he adds. "She doesn’t want you to use a condom, so you better find a way to kill your sperm count without her knowing because I will sooner die before having my bloodline be tainted by worthless trash like you. Are we clear?"

Before you could answer yes or no Amy appears in the doorway, wrapped in a towel. "You two getting along?"

"Like family," Greg replies, clapping you on the shoulder with painful ****.
