Inch by throbbing inch, I pushed into her. Her flower-pussy was impossibly tight, a silken vice that squeezed and rippled around my cockhead as I breached her depths for the first time. A soft, guttural moan escaped her lips, her body trembling with a mixture of pain and pleasure. I felt a thin barrier of resistance, her hymen, and I paused, giving her a moment to adjust.
"It's okay, my little Yagi," I soothed, my hands gripping her hips, holding her steady. "Just relax. Let Mommy in. Let me fill you up completely."
I named her Yagi, short and alternative for 'Yggdrasil'; that name is hard to pronounce, and I didn't want to call her Little Sprout forever or use a name that came from the Norse pantheon.
Just thinking about that one-eyed bastard made me want to kill him all over again.
Yagi nodded, her emerald eyes filled with trust and adoration. She took a deep breath, her flower-pussy relaxing its grip just enough.
That was all the invitation I needed.
With a powerful thrust, I broke through her barrier, burying myself to the hilt in one swift motion.
"KYAAAAHH~!"
A high-pitched, blissful scream tore from Yagi's throat as her virginity was taken. Her back arched, her hands clenching into fists as a wave of pure, unadulterated pleasure washed over her. Her inner walls spasmed, milking my cock, her nectar gushing out to drench my balls.
"Fuck yes! That's it, baby girl! Take Mommy's cock!" I roared, my hips starting a punishing rhythm, pulling out until only the tip remained inside before slamming back in, my balls slapping against her ass with wet, meaty smacks.
The chamber echoed with the sounds of our rough, primal mating. Yagi's moans and cries, my grunts and growls, the wet, squelching sounds of my cock pistoning in and out of her tight little cunt.
Then something else happened.
I sensed two strange things.
First, Yagi began to suck the divine energy from me—with my permission, of course—it was a passive siphoning, and the amount was small.
Second, I sensed a third existence, casting its gaze at us from the far, far void.
The universal world tree.
The mother of all world trees.
And she was very happy.
Happy for the birth and the awakening of a new world tree, and extremely happy that her new 'granddaughter' was being bred.
I sensed her approval and her blessing.
And with that blessing, it asked my permission to participate.
'Of course, mother-in-law,' I sent my thoughts to the cosmic entity. 'Come join the fun. Let's make this a family affair.'
Instantly, I felt a wave of immense, ancient, and purely divine energy wash over me. It wasn't just power; it was the essence of creation itself, the raw, untamed force that had birthed galaxies and shaped reality. It was the Universal World Tree's blessing, and it was intoxicating.
It caused my body to change form to adapt to her energy.
My futa-cock swelled, growing thicker and longer, veins glowing with a golden light. My balls churned, filling with a prodigious amount of cum, my desire to breed Yagi magnified a thousandfold.
"Mother... what's... happening?" Yagi stammered, her eyes wide with a mix of fear and awe. She turned, glancing over her shoulder, only to see the changes.
My pale skin turned green; its texture changed to that of tree bark. Intricate glowing golden runes appeared on my body, my silver hair turned to vines and golden leaves, and my crimson eyes now glowed with the light of a star.
I looked like a goddess of nature, a primal, elemental being of immense power.
The Dryad Form.
"Don't worry, my little Yagi," I purred, my voice now a deep, resonant hum that vibrated through the very core of her being. "Grandma is just giving us a little... boost."
With that, I resumed my thrusting, my movements now more powerful, more deliberate, each thrust a declaration of my dominance, a promise of the pleasure I was about to unleash upon her.
"MOTHER~! GRANDMOTHER~! SO... SO... GOOD~!" Yagi screamed, her body writhing in ecstasy as my transformed cock stretched her to her limits, filling her completely.
The energy of the Universal World Tree flowed through me, into Yagi, and then back again, creating a feedback loop of pure, unadulterated pleasure and power.
I felt the roots of Yagi's consciousness digging deeper into my own, our souls intertwining, our essences merging.
Soon, green veins as thick as my arms erupted from the floor of the chamber, wrapping around Yagi and me, holding us together, binding us in a shared embrace. They pulsed with the same rhythm as my thrusts, with the same beat of our hearts.
This wasn't just sex anymore.
This was a sacred ritual.
A union of mother and daughter, of mortal and divine, of two worlds becoming one.
"Ahhh~... Yeah~" I let out a long, shuddering moan, feeling two thick, green vines with glowing tips push against my asshole and my empty pussy. "Horny grandma."
They didn't wait for permission. They plunged in, their girth stretching me wide, their length burying deep inside my holes, their movements perfectly synchronized with my own thrusts into Yagi.
"FUCK~!" I cried out, my body convulsing with pleasure as I was filled from all sides. My cock swelled even more.
"Grandma wants to join the breeding party? Then breed Mommy's holes while I knock up your granddaughter!"
The sensation was unlike anything I had ever experienced. Usually, I was the one doing the colonizing, the one planting the seeds and claiming the territory. But as the Universal World Tree's "fingers" filled my own voids, I felt the sheer, staggering scale of an entity that spanned dimensions.
"Fuuuuck~! Yes, Grandma! Stretch Mommy's slutty holes!" I howled, my Dryad form shuddering as the vines fucked me raw, their textured lengths dragging against my walls with delicious friction.
Yagi's tiny body bucked beneath me, her emerald hair whipping like living vines as she screamed in rapture.
"M-MOMMY~! GRANDMA~! LITTLE SPROUT'S FLOWER... BREAKING~! SO FULL~! CUMMING ALREADY~!"
Her pussy clamped down like a velvet fist, spasming wildly as her first real orgasm ripped through her. Nectar exploded from her depths, squirting around my pistoning shaft in hot, sticky jets that soaked my bark-thighs and puddled on the chamber floor. I didn't let up—SLAM! SLAM! SLAM!—my hips a blur, balls churning with breeder-cum amplified by Grandma's blessing, slapping her clit with every plunge.
The vines in me accelerated, twisting deeper, their tips swelling to grind my G-spot and prostate in tandem. I felt Grandma's consciousness humming through them—a vast, maternal presence, amused and aroused.
'Good breeding, little goddess,' her voice rustled in my mind, like galaxies whispering secrets. 'Fill her womb. Make the child of my child bloom with life.'
"Ohhh, you cosmic slut~," I gasped back telepathically, grinning feral as another vine slithered up from the floor, wrapping my futa-cock's base like a cock ring, squeezing to trap my load. "Joining in properly? Pump Grandma's sap into my balls—make me flood this loli-cunt!"
She obliged. The vine pulsed, injecting thick, glowing nectar straight into my sack, bloating it until it hung heavy and taut, sloshing with hyper-potent seed. My cock grew another inch inside Yagi, stretching her obscene, her belly bulging visibly with my outline.
"MOOOOMMMIIIIIEEEE~!" Yagi wailed, drool bubbling from her lips, her budding tits heaving as roots from her own tree-body erupted to fondle them, pinching her tiny nipples until milky sap beaded there. Her glow intensified, the chamber shaking as her power surged, roots bursting through the walls to caress us both—teasing my swinging tits, coiling my silver-vine hair.
The feedback loop hit a critical point. Energy cycled: Grandma → Me → Yagi → Back to me.
A divine circuit of lust that made stars explode behind my eyes. My thrusts turned savage, jackhammering her cervix, battering it open for the breeding to come.
"Cum for Mommy again, Yagi! Milk my cock—beg for your sister's seed!" I snarled, one bark-hand yanking her hair back, the other spanking her juicy little ass CRACK! until it glowed red under the green skin.
"PLEASE~! GRANDMA~ MOMMY~! BREED YAGI~! FILL MY WOMB WITH BABIES~! MAKE ME SWELL LIKE AELI~!" she begged, her voice a broken chirp-chorus, her pussy rippling in pre-orgasm waves.
That did it. My balls tightened, vines fucking me into oblivion as I roared,
"CUMMING! TAKE IT ALL, DAUGHTER-SLUT!"
My cock erupted like a geyser, thick ropes of star-hot breeder-cum blasting her womb, inflating her tiny belly in seconds. She ballooned, rounding out pregnant in an instant, her flower-pussy overflowing with creamy white mixed with glowing sap.
"KYAAAAAAAAAHHH~!" Yagi's climax hit supernova, her nectar tsunami drenching us, vines from her core exploding outward, cracking the chamber open to the sky.
"FUUUUCK~!"
Grandma's vines climaxed too, flooding my ass and pussy with endless cosmic sap, bloating my guts until I sloshed and leaked from every hole. The overflow triggered chain reactions: my milk lactation surged, spraying arcs from my tits.
Panting, I pulled out with a POP!, a torrent of cum-nectar gushing from Yagi's ruined cunt. She collapsed into my arms, belly swollen, huge, a blissful smile on her face as she nuzzled my leaking nipple.
"Mommy... Little Yagi... pregnant... happy..." she murmured, already glowing with new life.
I kissed her forehead, vines retracting as Grandma's presence faded with a satisfied rustle.
'Well-bred, kin. Call when the grove needs tending.'
"Hehe~ A perfect start for the family night,"
