Chapter 19: A Step Toward Adulthood
When a man has sex for the first time, there are three main obstacles: darkness, finding the right spot, and the hymen. Of these, darkness is the easiest to overcome once you get used to it. The hymen isn't always a big issue either, as it may have already disappeared during the woman's maturation, or barely exist at all. The hardest part is finding the right spot. Many men fail at their first attempt because they can't find the entrance, ruining the mood and the act itself. If the woman is attentive, she may guide her partner or even position the man's penis herself.
But perhaps because his partner was his mother, or because of Ru's prior education, or maybe from his experience with other women, Milk had no trouble finding Millie's entrance and pressed his penis in. Millie, already well lubricated, gently squeezed him and accepted him all the way to her deepest part.
"Haaah!!!"
A heavy, pounding sensation, the feeling of hardness and heat all of it stimulated Millie's body and brought her pleasure. At such a young age, Milk's penis was already long and thick enough to reach the womb of an adult Holstaurus woman. As his length scratched her eager insides, her vaginal walls clamored for more movement.
'Amazing! Ah... my son is amazing... I'm completely filled inside. Oh! Incredible. I can tell just from the insertion he's the best!'
Stunned, Millie was unable to move, impaled by her son's member. Milk, settled between her spread thighs, grabbed her legs and spread them even wider. He pulled his hips back, then thrust forcefully into the very place he was born. Millie's back arched like a bow.
"Huaaah!!!"
It was dizzying. The head of Milk's penis jabbed her cervix. The son she bore was now pounding the place where he was born, and Millie was so aroused that her vagina was soaked.
Even after ejaculating once, Milk was still so healthy she couldn't imagine how powerful he'd be when he grew up. His thrusts were simple, but that didn't matter. The situation, the mood, and the mother-son relationship all heightened the pleasure.
'Ugh! My hips...'
Still, Milk's age showed his hips started to tire, and Millie's tightening grip made it harder to move.
Should he speed up and finish, or keep this pace and last longer? Milk stood at a crossroads.
But Millie, ever the mother, noticed the subtle change in his movements and watched his face.
'He's struggling... Well, no wonder he's only eight...'
Millie, noticing his weakening thrusts, regained her composure. But she had no intention of stopping. She was the type to see things through once started.
She gently embraced Milk, stopping his thrusts and pulling him against her chest.
"Mom?!"
Still holding him, Millie rolled over so that Milk was now beneath her, lying on his back on the bed.
Taking the superior position, Millie braced herself on the bed so as not to put her weight on him. She decided: 'I'll do it... If we're doing this, I'll serve him.'
With surprising flexibility for her voluptuous body, she began to move her hips in circles, raising and lowering her buttocks on top of him. The swirling pressure inside her made Milk's penis even harder.
"Huaa! M-mom~!"
"Aah... Does it feel good, Milk? Do you like being inside Mom?"
"It feels amazing! Mom, you're so tight and soft, it feels like my penis is being sucked out. I love it, Mom~!"
"Haha, you say the nicest things! My son... mm!!! I love it too... Ah... My son's penis feels so good... I'm so happy!"
Now able to talk as they moved, their pace quickened, and the room filled with the wet sounds of sex. Fluids flowed freely from their joining, soaking the bed and straw beneath.
With Millie on top, Milk's penis jabbed straight into her womb, making her even more excited and increasing her pace. Milk, feeling better, began to thrust up in time with her, and soon they were both lost in pleasure, unable to speak, focused only on each other's bodies.
Millie bent down, and Milk, understanding, lifted his head to meet her lips. She took the lead in the French kiss this time, slipping her tongue into his mouth, and he welcomed her, their tongues dancing together.
"Mmm!!! Mmm! Hwap! Chup! Churup!"
"Haa... Hwap! Chuwup! Churu!"
Their mouths made wet, sucking sounds, harmonizing with the noises from below.
Sensing the time was right, Millie gently hugged Milk and rolled over again, putting herself beneath him and Milk back on top.
"For the last part, do whatever you want... Make Mom feel good, okay?"
It was her way of boosting his confidence. Milk responded by thrusting hard into her.
"Huaaak!!!"
It was intense. Millie's words excited him, and his sex became a bit rougher. But they were Holstaurus stronger than humans, and Milk was even stronger than most Holstaurus males.
Ru's enhancements were undeniable. Milk lifted Millie's legs, surprising her as her lower body rose.
'Wow! My son is strong! Ah! I love this position! He's reaching my womb... This is mating... Ah! Mating!'
With her legs raised and her hips bent, Milk maintained the position and slammed his penis deep into her.
Despite her large body, Millie was completely dominated by the small Milk, and she found it even more exciting.
"Ah! Ah! So good! My son's penis is amazing! I'm so happy, Milk!"
"Huff! Huff! I love you, Mom! I love you!"
"I-I love you too, my son! Ah! I love you, Milk!"
"Millie!!!"
"Aah!!! Milk!!!"
At the last moment, Milk dropped the word "Mom" and called her by name, the impact of which shook Millie to her core.
As Milk began to climax, Millie stared blankly at the ceiling, her trembling body a testament to the greatest pleasure she'd ever felt.
The ejaculation was long and intense, continuing until all the milk in Milk's rear testicles was spent.
Her belly swelled, her womb was shocked, and Millie trembled in the endless waves of pleasure.
Ru had never mentioned it, but Holstaurus women's vaginas rapidly absorb semen, increasing the chance of pregnancy and quick conception. But since Milk had no sperm yet, Millie's womb simply absorbed the nutrient-rich milk.
The absorbed milk would quickly spread through her body and be converted into nutrients, a return for the milk she'd given Milk.
When it was over, Milk collapsed into Millie's arms, his hips and legs trembling, unable to move.
Sweaty Millie's breasts leaked milk, and Milk instinctively nursed, quickly regaining his strength and relieving his hip pain. His eyes regained their light.
With renewed energy, Milk rose and began to thrust into his mother again.
"Ah! Aaah!!! Milk! Ah! Aaah!!!"
Even though his testicles were empty, he didn't stop. Now, he was marking Millie as his, leaving his shape inside her.
Millie's insides, probably shaped by Honkale before, were now being reshaped by Milk's penis.
"Paha!"
Milk stopped nursing and focused on thrusting again, his only thought to make the woman before him his own.
"Millie! Millie!!!"
"Milk!!!"
Their movements stopped as they called each other's names, trembling together in overwhelming pleasure.
For the first time, Milk experienced a true ejaculation with semen, not just milk.
"Hh... Uuugh!!! Uaaah!!!"
His testicles and penis felt like they were on fire, and he felt the powerful pressure of semen shooting out.
Compared to his human life, the pleasure was incomparable like heavy jelly being pushed out.
Millie immediately sensed this ejaculation was different and realized Milk had become an adult again.
'Ah! It's coming in! Ah, so hot! My son's semen is inside me! He's making me a mother again! Ah, Milk! Aaah!!!'
Gush, gush!
Sploosh!!!
Ejaculation with semen was short but incredibly intense, unlike the long, drawn-out pleasure of milk ejaculation.
Completely spent, Milk collapsed onto Millie, licking her milk-soaked breasts as his penis shrank.
Soon, his penis slipped out and retracted into the foreskin he was totally drained.
He nursed from Millie's leaking breast, but didn't recover further apparently, the effect was only temporary.
Millie hugged and patted his back, and as he relaxed, Milk drifted off to sleep.
[Vitals normal. Due to rapid loss of energy, you are fatigued estimated recovery time: 6 hours. Well done, Milk. You have also successfully cleared the achievement quest.]
'Yeah... but I'm so tired... Sorry, I'm going to sleep now.'
[I'll take care of the rest. Sleep well, Milk.]
"Good night, my son... No... good night, dear..."
With his mother's and Ru's voices in his ears and mind, Milk fell into a deep sleep, a happy smile on his face.
His first experience had been with Millie, making his mother his first wife a truly meaningful day.
