As he tasted the heavenly smoothness of Benihime's tongue, Ryuuji couldn't hold his hands, which automatically went to the red-haired woman's slim waist in his embrace.

Ryuuji wasted no time and began squeezing the soft flesh of his mother's body, as the two fought a battle for sovereignty with their tongues.

The two tongues were twirling and intertwining as the mother and son couple kept their gazes fixed on each other.

His mother's muffled moans were causing Ryuuji to get more and more out of control, until his hands descended from her slim waist to Benihime's full heart-shaped ass, who let out a muffled moan a little louder.

Feeling her son's strong hands on her ass, Benihime lost concentration in their oral battle for a few moments, moments that Ryuuji didn't waste.

With his tongue now dominating Benihime's tongue, Ryuuji started massaging his mother's ass cheeks. The red-haired boy squeezed, kneaded and molded the flesh that had always been in his thoughts.

With Benihime turning into a soft mass in his kiss and in his embrace, Ryuuji pulled her body even closer, making his throbbing cock fit perfectly between her thick thighs.

As Ryuuji was already slightly taller than his mother, his cock fitted perfectly between the swollen and wet lips of Benihime's slit. Ryuuji couldn't keep the euphoria and lust from his body and started moving his hips back and forth.

Benihime broke the kiss to catch her breath, but as soon as her mouth was free of Ryuuji's lips, she closed her eyes and arched her spine, letting out a pleasure-filled moan.

" Ahn~~ Ryuuji…g-go on. Keep doing it! "

Ryuuji did as his mother asked him and kept moving his waist, adding a little vertical tilt to his hip to rub his glans and cock all the way between his mother's lower lips.

Feeling Benihime's soft body in his hands and the hot liquid running all over his member, Ryuuji felt his cock throbbing again.

Benihime felt that her son was about to have his first orgasm and quickly gave up her pleasure to get Ryuuji's first load.

Ryuuji let out a disappointed sigh as the heat coming from his mother's pussy faded, but the scene that followed made him swallow hard.

Benihime got down on her knees in front of Ryuuji and without thinking twice, planted a tender kiss on the glans of her son's penis.

" Fufufu~ Ryuu-kun…your cock are so anxious. Do you want to cum in your mother so badly? "

Benihime returned to masturbate her son's member with her silky hands, drawing a throaty moan from Ryuuji.

" Y-Yes, Mom! I want to cum! I want to cum in your mouth! "

Benihime smiled with lust and amusement and licked her lips before opening her mouth and moving her head forward.

When Ryuuji felt the wet heat cover his member's head, he sighed in pleasure.

" F-Fuck! "

Benihime, with a smile in her eyes, kept moving her head forward until half of Ryuuji's cock was in her mouth and at the top of her throat.

Ryuuji unconsciously placed one of his hands in Benihime's red hair, squeezing a handful of it tightly, as if holding a handle that allowed him to move his mother's head.

The red haired boy started to move his waist slightly, synchronizing his movements with the way Benihime moved her head.

Feeling the hot saliva and tight insides of his mother's mouth, Ryuuji began to feel his testicles twitch tightly.

Benihime continued with the smile in her eyes and increased the speed of her movements, letting more and more saliva cover her beloved son's cock.

" M-Mommy! "

Benihime took one of her hands between her thighs and started jerking off frantically, loving the way her son moaned and writhed as he received her blowjob.

The way she was dominating Ryuuji using only her mouth left her amazed and she knew it wouldn't be long before she finally had an orgasm after years of waiting.

The wet, sticky noise of Benihime swallowing Ryuuji's penis almost whole rang through the thermal bath along with Ryuuji's moans of pleasure.

" M-Mom, I can't take it anymore! "

Benihime, who never took her eyes off Ryuuji, used her intimacy and experience with Ryuuji to practically send a telepathic message.

Seeing her mother's eyes practically begging him to come in her mouth, Ryuuji exploded with pleasure and lust.

" F-Fuck, Mom! "

Ryuuji threw off the restraints and thrust his hips forward, placing his big, thick cock completely in Benihime's mouth, who accepted all of her son with pleasure.

Seeing Benihime shudder with pleasure at having his entire cock in her mouth and throat, Ryuuji let out one last throaty growl and finally got the release he so craved.

A strong shot of thick white semen went straight down Benihime's throat, and upon feeling the texture and taste of her son's cream, she closed her eyes and shivered.

" Hmmmm! "

Seeing that his mother reached orgasm while serving him orally, Ryuuji grew even more lustful and kept releasing string after string of thick cum.

Ryuuji wanted his mother to taste his semen better, so he pulled back his waist slightly so that only the glans of his meat stick was inside her mouth.

Releasing a few more shots of cum, Ryuuji finally felt the height of his pleasure pass.

Benihime turned her face away from Ryuuji's member and with puffy cheeks, looked at Ryuuji as she slowly swallowed her son's cream.

Seeing the scene of his mother kneeling down drinking his sperm as if it were a rare and delicious drink, Ryuuji felt another pang of pleasure and from the tip of his still erect penis, a string of white sperm flew, landing on Benihime's face.

Benihime smiled at her son and finished swallowing all the cream she received as a reward for her oral work. The red-haired MILF opened her soft little mouth and stuck out her tongue, showing Ryuuji that there was no more of his sperm in her mouth.

Benihime used her tongue to capture the sperm that Ryuuji released on her face and after that, she used her thin and delicate fingers to take every drop of hot cum from her face and take it to her mouth.

Ryuuji's cock wouldn't stop throbbing involuntarily at the sight of Benihime's actions.

Ryuuji was totally speechless. He'd always known his mother wasn't a normal woman when it came to lust, but seeing his mother acting like his personal bitch was something that made him lose what little sanity was left inside him.

Benihime scaled the large rock Ryuuji was leaning on, allowing her son to see how wet and swollen its crevice was. Maybe it wasn't the woman's intention, but this act put Ryuuji into a trance-like state as he watched that big, heart-shaped ass.

Benihime lay down on the rock and patted the side, asking Ryuuji to lie down next to her.

Ryuuji levitated and did just that. He hugged Benihime's body and brought one of her pink nipples to his lips, while using his fingers to play with the other nipple.

Benihime smiled and crossed her leg around Ryuuji's body, making their bodies entwine like two previously lost halves that were now together again.

" Fufufu~ You've always loved my breasts, haven't you, Ryuuji? "

Ryuuji nodded slightly with his head while still playing and sucking on his beloved mother's breasts, not taking his eyes off Benihime's beautiful flushed face, which looked even more beautiful after the incestuous orgasm they both had.

Seeing her son so intent on playing with her breasts, Benihime teased him:

" It's no use you sucking my nipple so hard…I don't have the milk you loved so much anymore. "

Remembering the taste of breast milk that his mother let him drink until he was five years old, Ryuuji felt his mind go into a trance.

He began to recall his countless memories of the times he'd sucked on his mother's lactating nipples and the various times he'd spent hours just looking at pictures of his mother during her pregnancy period.

Ryuuji tried to stop the thoughts that were flooding his mind, but at this point it was impossible.

Benihime noticed that Ryuuji's erect penis started to pulse and become more swollen and was slightly surprised.

" Eep! "

The redhead let out a little yelp of surprise as Ryuuji practically mounted her, trapping her body in the rock that held them both up. Benihime noticed that Ryuuji's eyes were slightly different and tried to stop her son from continuing.

Ryuuji couldn't control the urge to be inside his mother, the overwhelming urge to put a baby in her womb.

Maybe it was because he was the only one of his kind and the instinct to perpetuate his DNA was very strong, but he felt he needed to impregnate his mother!

" Ryuu-kun! Listen to Mom…you're still too young for that! "

Ryuuji looked into his mother's eyes and captured the red-haired woman's lips. Benihime didn't know what was happening to Ryuuji, but she was also too excited to force Ryuuji off her.

Benihime felt her barriers being slowly broken, until after a minute of a wet and intense kiss, she hugged Ryuuji's neck pulling him closer to her.

Ryuuji continued kissing his mother as he guided the situation forward. He placed his hands on the backs of Benihime's knees and lifted the woman's legs, putting her legs up as he supported them on his shoulders.

Ryuuji threw his torso forward, forcing Benihime to practically bend her body in half as she was pressed down by Ryuuji's muscular and powerful body.

" Mom…Mom…I need it! I need it! "

Benihime realized that her son was practically begging her to stop him from continuing, otherwise he'll actually invade her insides and mold her body to his shape.

Benihime's mind tried to fight the desire her body felt, but it was impossible.

She had always been a strange woman who felt desire and love for her own flesh and blood, so at this point where Ryuuji was basically acting on his pure instinct, she also started to give in more and more to the unhealthy desires that had always been on her mind, no caring about Ryuuji's young age.

Benihime brought Ryuuji's ear close to her lips and spoke in a voice full of desire:

" Come on, Ryuuji…go back inside mommy. "
