A hot aunt in the hot spring (R-18)

Ayra wandered her way towards the hot spring. The training had been long and exhausting, and she eagerly anticipated the soothing embrace of the steaming water against her tired muscles.

She was tired because she had to fight with Garnt. Even though she remained confident in front of him when she was fighting with him, she felt really inferior to him since she knew in another one or two years he would easily surpass her strength.

"I can't let him beat me, I should get stronger if I want to support him," She muttered to herself, as she looked at the hot and steaming hot springs.

The air was cool, causing a shiver to run down Ayra's spine as she stood beside the serene pool. The steam rose in delicate tendrils, veiling the surface in a mysterious mist. With a determined breath, she began to undo the ties of her lower clothes. First, the intricate straps that held her worn tunic in place slid over her erotic hips, revealing the creamy expanse of her skin underneath. The fabric whispered softly as it slipped to the ground, pooling around her feet.

A wistful sigh escaped her lips as Ayra's deft fingers found the fastenings of her undergarments. The fabric loosened, and she let them slide down her legs, revealing the gentle curve of her hips and the softness of her gorgeous ass. She hesitated for a moment, a playful smile tugging at her lips as she glanced around, ensuring her privacy in this hidden corner of nature.

"I don't understand why I have to wear this thing called 'underwear', Garnt really comes up with some bizarre ideas," Ayra quickly took both the pieces of clothes she removed and kept them on a rock, so they wouldn't get muddy from the sand.

Her heart raced as a rush of cool air caressed her bare skin, the sensation sending a tingling thrill through her entire body.

The hotspring beckoned, its warm embrace promising to chase away the fatigue that clung to her bones. Ayra stepped into the water, a delighted gasp escaping her lips as the heat enveloped her, tendrils of warmth snaking around her every curve. She sank deeper, until the water rose to her collarbone, concealing her ample breast beneath its opalescent surface.

As she leaned back against the smooth rocks, her eyes closed in sheer contentment.

"Kuuuuuh~ this really hits the spot, I'm surprised my previous cave didn't have something like this," The feeling of the hot water was almost orgasmic for the fatigued body of Ayra, so much that she might have immediately fallen asleep if not for her duties.

While she was enjoying her bath, Ayra didn't expect to have a peeping tom watching her as Garnt kept watching her undressing and entering the bath with a weird look on his face. His face was flushed and he had no idea what was happening. He had a big tent forming in his lower body, which confused him for a minute.

Caught off guard, Garnt stumbled over a loose stone, his heart pounding like a frantic drum.

"Eva, what's happening to me? Is this a disease? I feel hot," Garnt asked with his eyes refusing to leave Ayra's figure.

[As I expected, you are looking at your aunt that way]

It wasn't just Garnt that felt weird seeing all these, since Eva also had to witness this young boy going through his puberty. Even though she had a doctorate in medical science, she had no idea how to deal with a teenage boy.

Without knowing what was happening on the other side of the wall, Ayra kept enjoying her bath until her face suddenly lit up as she had a sudden realization.

"Damn it, they are getting heavy again, I might as well-" She muttered and under the hungry eyes of Garnt, she started to squeeze her boobs causing milk to come out of them. Since she became a mother recently, she had a lot of milk collected in her mammary glands that she didn't even have to use since her son wasn't a hungry baby.

So as a routine, she always got rid of her excess milk feeling the little bit of uncomfortable feeling it can bring when it gets collected too much. Being a mother in the Stone Age was not easy since they always produced milk for at least eight years after giving birth.

This was the last trigger Garnt needed, as his hand automatically went into his pants and out of his pure instinct, he started to stroke his cock so fast that Eva was worried that he might harm his reproductive organ.

[Idiot! Don't act like a mad man, slow down, you will harm your organ like this]

Eva had an existential crisis as she had to wonder, how she went from a world-renowned doctor to a woman who had to witness the puberty of a stone-age teenage boy.

"I-I can't- I can't- this feels good." Garnt was in his own world, as he kept stroking his cock slowly after Eva scolded him, Ayra also kept squeezing her breast while moaning a little feeling good from the sensation.

It didn't even take a few minutes for Garnt to feel something strange happening. He felt something was about to come out of his body and he had no idea what it was going to be. This was a new feeling, he never experienced before but he knew it wasn't an unpleasant one.

"Ayra! It's coming out, something is out, Eva, what am I going to do?" Garnt questioned worried he might have done something wrong and Eva being the adult decided to give proper advice to him, so he wouldn't mess up his first ejaculation.

[Take it slowly and embrace whatever you're feeling. Don't hesitate, let it come out]

"Ughhhhhhhh~ it's out," Garnt moaned in pleasure and his body started to twitch, but unlike what Eva expected nothing came out of his lower part which caused her to be a little worried, but then she understood that he was too young to be producing sperm.

[I guess it is just a dry orgasm. Why do I have to do this?]

Eva sighed feeling weird about this whole situation, but things didn't end there as she felt a presence behind Garnt and she quickly advised Garnt to get up. His lower body was weak from the sensation but pushing his body to the limit, he turned his head to see Gundo smiling at him with a happy look on her face.

[Ahh~ She was looking at you]

Garnt didn't look guilty or anything, since he had no idea what he did was taboo, at least in Eva's standard but Gundo just smiled at Garnt and left the place without telling him anything, which confused both Eva and Garnt.

"She looks happy," Garnt muttered, but Eva quickly asked him to leave this place before Ayra finished her bath and he did just that.
