Time for a sequel

You pulled Stacey up into my arms and kissed her fervently, wrapping your arms around her, pressing her breasts to your chest as your lips locked. Your tongues intertwined and she cooed, melting into your arms. "Alright, I'm ready." She said, leaning back, her arms still on your shoulders, showing you her pussy, which was dribbling seed onto the bed. "Show me what you got."

You nod, grabbing the marker from where you had placed it and uncapping it. You gestured for her to turn around and she did. Underneath all of the other things written on her back, including "Elastic Holes" you wrote, "No need for other organs", "Elastic, Indestructible Womb" and "Pussy can stretch to fill her entire torso and connects to her throat". Then, for her you wrote, "Size Queen" and "The more cum inside her, the more powerful the orgasm". Then, after considering it, you also write, "Limbless" on her. Stacey suddenly shifted and fell forward, her limbs withdrawing back inside her body, leaving her only with small stumps. "Finn?" She said in surprise, wiggling what was left of her arms and legs. "Come on, we already did this."

You grabbed Stacey gently and flipped her around, so she was propped up on the pillows, next to Olivia, who was still catatonic from the fucking you gave her. "I have something special planned," you insisted. "Trust me, this is just to make it easier." Stacey tried to look like she thought this was all dull, but you could see the anticipation in her eyes. "Fine," she said. "I'll indulge you." You smiled at that, then twirling the marker around your fingers, you began to write on yourself. First, you crossed out "Shape-Shifting", you wouldn't need that.

Then you wrote, "Eight Feet Tall" and "Olympian Build". Your body swelled to an enormous size, nearly double Stacey's height, every muscle swelling and molding itself into the model of masculine perfection. You looked like something that should be carved of marble in an art museum. You kept going, adding "Three Foot Cock, 1 Foot Wide", "Cantaloupe Sized Balls" and "Produces 4 Gallons of Cum". Your shaft grew and thickened like a sapling growing in a time lapse photo, becoming the most fearsome rod any man had ever wielded. Meanwhile, your balls swelled as well, becoming the world's most powerful engine of impregnation.

Stacey trembled a little at the sight of your new cock. Was she scared? Had you gone too far? No, you realized as she bit her lower lip. She was eager. Her pussy began to glitter, the ropy strands of cum mixing with her juices in a beautiful display, like she was hanging strings of pearls between her pussy lips. You leaned over her and kissed her with your oversized lips, then picked her up like she was a toy, one massive hand around her waist being all that was required. Stacey just smiled. "You're huge," she commented, her tone attempting humor while her eyes betrayed her true feelings. They running over your new body, before locking onto your cock. "It's, massive." You nodded, then turned her around, so you could get a better view of her toned ass. "Hey wait," she called. "I want to see it go inside."

You ignored her, and pressed her slit up against your battering ram. "Don't worry, I'm certain you'll be acquainted soon enough," you groaned, the soaking wetness of her pussy slurping at your cock's engorged head. Then, with a little more effort, you began pulling her down the shaft, spreading her wider and wider. "Oh God!" Stacey cried as her pussy stretched like the opening petals of a flower. "It's so BIG!" You pulled her down further, your cock barely a quarter in before it was slowed by her cervix. "Oh Finn, that's my womb! You're kissing my womb!" You felt your cock pulse in eagerness at the thought of Stacey's womb, and you accelerated.

With a single, brutal thrust you shoved your way inside, smashing Stacey's defenses. She screamed as you invaded her womb, your cock occupying the space. Your head quickly ran out of room again, bumping into the walls of the same, making Stacey groan, shuddering around you. "Oh Finn, I'm so full," she whimpered. "God, it's so good!" You smiled, your teeth flashing. "Wait until you feel the other half."

Stacey arched her back, looking up at you. "Half?" Her expression was a mixture of shock and rapture. You nodded, then pulled her down the rest of the way. Her womb stretched like a balloon, the contents of her body being shoved up and out of the way. Then it stretched even further, parts of her pussy she didn't even know she had unfolding to welcome this monster. You felt your cock enter her upper chest, your cock able to feel the thundering of her heart on the other side of her wall. And what walls they were, each one ribbed and folded, glistening and welcoming, wrapped around him like plastic wrap.

Finally, you reached the end, your cock just barely shy of the bottom of Stacey's throat. You felt her lungs gasping for air just above it, warm and cool air flowing over your pre-dripping head as she inhaled and exhaled. You groaned in ecstasy, struggling not to cum. Then, once you slipped back off the peak, you began to work her.

Up and down, up and down, you plunged in and out of her pussy, stuffing her, teasing her with emptiness, before going even further. You worked her body up and down your shaft, her every inch heaven for you. She was screaming, but you could barely hear over the slap! slap! of your titanic balls against her perfect pussy lips.

"Fuck! Fuck! Fugghghghah," Stacey screamed, her voice getting mangled as you approached the apex of her thrust. "Impregnattththh mmmiiiiiiEEEEEEEE!" At that point, her voice lost all coherence, becoming a series of shrill, animal cries. You harmonized with her, pounding her to the rhythm of her screams. She was incredible, every square centimeter flooding your brain with pleasure, drowning your self-control in an ocean of pure bliss. Finally, the roar in your ears became the tightness in your loins and you couldn't stop it.

You clenched tight, then popped. An avalanche of cum flooded Stacey's insides, making her womb swell like a balloon. But you kept going, overwhelming even the elastic properties of it, the fluid **** to try and push past your mammoth member or rise higher. It choose the latter, flooding Stacey's throat and exploding out her mouth, a jet of white that splattered the wall, bed and Olivia, painting them all white, burying them under a thick layer of fertile seed.

You set Stacey down amidst the cum and sat down yourself, needing to rest for a moment. You felt light-headed, your whole body trembling with the **** of your orgasm. "I'll just rest them for a moment," you thought to yourself. Then, closing your eyes, you promptly passed out.
