Andy’s eyes were glazed with raw, animalistic lust as she shoved me forcefully onto my back atop the thick pile of soft furs that served as their communal bedding in the dim, firelit cave.

The primitive beauty, with her sun-kissed skin glistening with a light sheen of sweat, swung one of her thick, powerful thighs over my hips and straddled me with commanding hunger.

She dragged her soaked, hairy pussy along the full, throbbing length of my massive cock, coating every thick, pulsing vein with her slippery, fragrant juices.

The wet, slick sounds of her arousal filled the warm air, mixing with the crackle of the nearby fire and the heavy breathing of her watching family.

I groaned loudly, my voice deep and theatrical, pretending to be utterly lost in overwhelming pleasure as her heat enveloped my cock. "Ughhh... Andy... your cunt is burning hot... so fucking wet... like a river of molten desire gripping me already."

She grabbed my fat, rock-hard cock with both hands, her fingers barely able to wrap fully around its immense girth. Lining up the swollen, bulbous head with her hairy, dripping entrance, she slowly sank down, her strong legs trembling with effort and anticipation.

"Aaaaaahhh—!!" Andy cried out sharply, her head snapping back in ecstasy and shock, her long dark hair whipping wildly. "It’s... It’s too big! Hnnngghhh...! It’s stretching me so wide... Much bigger than Rikaru’s! Oh gods, I feel every ridge, every vein splitting me open!"

Her primitive pussy stretched obscenely around my girth, the dark curly hairs matted and shining with her thick cream as her puffy lips formed a tight, shiny ring that clung desperately to my cock. Inch after thick inch disappeared inside her as she kept pushing down, her inner walls fluttering and clenching in resistance and welcome. Then—

Thump.

The fat head of my cock slammed hard against her cervix with unyielding force.

Andy’s eyes flew wide open in complete, overwhelming shock. Her mouth hung open in a perfect O as a broken, guttural moan tore from her throat, echoing off the cave walls.

"AAAAHHH—!! What... what is that?!" she gasped loudly, her voice trembling with confusion and raw pleasure.

"Something... something deep inside me! It’s hitting the very end... the deepest place inside my belly! I’ve never felt anything touch there before! It’s so deep... so impossibly deep!"

She froze for a long moment, panting heavily, her powerful abdominal muscles twitching as her walls spasmed wildly around my buried cock, milking me with rhythmic contractions. Her massive breasts heaved with each ragged breath, nipples stiff and dark in the firelight.

Still impaled and overwhelmed, Andy turned her head toward Nara, her mother-in-law, who was watching everything with rapt, unblinking intensity from the side.

"Mother," Andy moaned breathlessly, her voice husky and broken while she remained fully seated on my cock. "His cock... It’s hitting something strange deep inside me! It keeps pressing against a soft spot at the very end... like it’s trying to enter my baby place!"

"Is this normal? I feel it so clearly... every time I move even a little, it kisses that deep spot! It’s making my whole body tremble!"

Nara — the older, experienced woman with her fuller, mature figure and heavy, swaying breasts — stared with wide eyes at the obscene junction where Andy’s pussy was stretched impossibly around my thick cock.

A prominent, visible bulge had formed in Andy’s lower belly, rising and falling lewdly with every tiny shift of her hips, the outline of my cockhead clearly visible beneath her skin.

"I... I don’t understand," Nara muttered, her voice thick with confusion and growing arousal. "I have never heard of a man’s cock reaching so deep into a woman. Is it really touching something that far inside? Look at how her belly moves... It’s like he’s rearranging her insides."

Andy rolled her hips experimentally, grinding down harder, and moaned even louder as my cockhead ground firmly against her cervix again and again. "Yes...! Right there! It’s pressing so hard against that deepest spot... It feels strange but so incredibly good... like it wants to go even deeper, to flood my womb directly! Haaah... I can’t stop moving!"

The entire family watched in stunned, breathless silence from around the fire. Rikaru’s eyes were bulging in disbelief and humiliated envy. "Look at her stomach... You can actually see his cock moving inside her! It’s bulging her belly like she’s already carrying his child!"

Dagu, the younger one, exclaimed with a shaking voice, "Mother’s pussy is expanding so much! It looks like it’s going to tear apart... but she’s still pushing down, taking more! How can she fit all of that?"

Haru added breathlessly, his own arousal evident, "That bulge... It’s reaching so deep into her! I’ve never seen anything like it. She’s moaning like an animal in heat."

Andy kept bouncing slowly at first, then with increasing rhythm, her massive tits jiggling and slapping heavily against her chest with every descent. The wet, squelching sounds of her creamy pussy devouring my cock grew louder, obscene, and hypnotic. Her juices flowed freely down my cock and balls, soaking the furs beneath us.

I groaned deeply again, pretending to struggle with the intensity. "Fuck... Andy... your insides are gripping me so tightly... rippling and squeezing like they never want to let go. I don’t know how much longer I can hold it... You’re going to milk me dry."

Nara watched for several more long moments, her initial confusion slowly melting away into burning curiosity and raw, maternal arousal. The older woman’s cheeks flushed deeply, her own hairy pussy visibly dripping down her thick thighs.

Finally, she stood up, her mature, voluptuous body swaying with heavy breasts and wide hips as she approached us with purposeful steps.

"I need to know for myself..." Nara said, her voice thick with lust and authority. "If it’s truly reaching such a strange, deep place inside you, daughter, then I must feel it myself. Andy, get off him for a moment. Let your mother-in-law experience this wonder."

Andy reluctantly lifted herself off my cock with a long, wet, obscene pop. A thick flood of her pearly juices poured out of her gaping, stretched pussy like a waterfall, cascading onto my glistening cock and coating it even more thoroughly.

She collapsed to the side, panting, legs spread, fingers instinctively reaching down to rub her swollen clit as she watched.

Nara quickly straddled me, her older but still incredibly voluptuous body hovering above my throbbing, vein-ridged cock.

She looked down between her thighs with hungry eyes, grabbed my slick, pussy-juice-covered cock with both hands, and pressed the fat, cum-smeared head firmly against her own hairy, mature entrance.
