The festival crowd grew more intense as the night deepened.
The three of them continued to explore the various stalls that lined the streets. Masha, with her unstoppable enthusiasm, pulled Ren from one stand to another, trying almost every food in sight, from charcoal-grilled yakitori to okonomiyaki still sizzling on the plate.
Although calmer, Alya was not to be left behind, her eyes sparkling every time she saw sweet dishes like taiyaki or refreshing shaved ice.
Ren, sandwiched between the two women, patiently—or rather, resignedly—followed their will, occasionally paying or showing his skills at the stall games to win small prizes that made Masha and Alya cheer with delight.
After they were satisfied with trying various foods and games, they decided to rest for a while, waiting for the fireworks display to begin. They found a comfortable spot on the green grass by the riverbank, with a good view of the sky.
Sitting relaxed, Ren was flanked by Masha on his left and Alya on his right. The low hum of the crowd and the aroma of food became the perfect backdrop.
"Ah~ I'm so full~ I can't eat anymore~" Masha complained, dramatically patting her bloated stomach.
"You ate too much, Masha. Be careful, you might gain weight." Alya glanced at her sister's swollen belly, as if she were pregnant, even though it was just a young pregnancy.
"Ugh, don't mention that. You're ruining the mood, Alya-chan." Masha protested with a pout. She then turned her face to Ren with hopeful, sparkling eyes. "Anyway, Ren-kun will still like me even if I get fat, right?"
"No." Ren answered bluntly, his gaze fixed forward. "I don't like fat women. Masha, if you really become a meatball, you'll have to leave the harem."
"Geez, Ren-kun is so mean!" Masha protested, but her tone was more a pout than anger. She had already guessed the answer. "In a situation like this, you should at least lie and say you'll still like me even if I get fat."
To vent her frustration, she weakly hit his chest a few times.
"I don't think we need to worry about getting fat." Alya suddenly interjected her sister's complaint.
"Ho~ why do you think so, Alya-chan?" Masha looked at her younger sister with curiosity.
"Considering the sexual activity we have almost every day with Ren-kun, the calories burned are far more than a regular workout at the gym."
"Ah, now that I think about it, Alya-chan's point makes sense. Phew~ that puts my mind at ease."
Seeing the two sisters quickly find comfort and justification in each other in the face of the cruel reality he had spoken, Ren just smiled faintly.
What he said was not a lie. He truly did not like fat women. His standards were high. If at any point one of the women in his harem crossed that line, he would not hesitate to discard them mercilessly, like throwing away something he no longer liked.
For him, they were a fulfillment of his sexual desires who must always meet his beauty and physical standards.
"Oh yeah, I heard that in Japan there's a custom of not wearing anything under a yukata, is that true?" Ren suddenly asked, breaking the comfortable silence between them.
Alya looked at him in surprise. "Seriously? You, Ren-kun, a Japanese person, are asking this to us two who are from Russia and have not lived in Japan for long?"
Masha giggled at the question. "Ren-kun is strange sometimes."
"Just because I'm Japanese doesn't mean I know everything about this country." Ren replied with a shrug, acting irresponsibly.
"Wanna know the answer?" Masha leaned her face closer to Ren, a mischievous smile on her lips. Her eyes sparkled meaningfully. "Why don't you verify it yourself, Ren-kun~?"
To emphasize her words, she intentionally lifted the bottom of her yukata slightly, revealing her smooth ankle and calf.
"Since you've offered, I'll generously accept."
In a flash, Ren had stood up and grabbed both Masha and Alya's hands, forcing them to stand.
"W-Where are we going, Ren-kun?" Alya asked, slightly stumbling.
"Somewhere more... private." Ren answered curtly, leading the two girls away from the crowd, towards the trees of the park behind them.
Alya and Masha looked at each other, their hearts pounding. They both guessed what Ren wanted to do in this secluded place.
"Alright. There's no one here." Ren released their hands and stood before them. "You two know what to do, right?"
"Ara ara~ Ren-kun is a pervert~" Masha giggled playfully, though her cheeks were also flushed. She was clearly excited by the idea.
"D-Doing lewd things in an open space..." Alya whispered, her face beet red with shame and a mix of emotions. "This... this is embarrassing..."
"Do it." Ren commanded, his tone leaving no room for negotiation.
There was no other choice. Masha and Alya obeyed. They bent down in unison, their hands reaching for the hem of their yukatas and slowly pulling them up to their waists. Under the moonlight, a sight of their completely naked lower bodies, without a single thread, was revealed. Their pale skin shone faintly, a contrast to the darkness of the night.
"You two really are sisters, huh..." Ren's eyes swept over the scene laid out before him. "Your lower parts got wet at the same time. It's like that twin telepathy theory."
Ren was a hot-blooded young man. That might be an understatement. In fact, he was a depraved man with an appetite like a male animal at the peak of mating season. Especially after becoming a Campione with inhumane stamina, his libido had reached a level that one or two women alone could not bear. That was why daily sexual relations were a must for him, an urgent biological need.
So, seeing Masha and Alya in this state in front of him, Ren's body immediately reacted. The lust that had been slightly ignited throughout the night now flared into a blazing fire.
"..."
Realizing the burning lust in his eyes, Masha and Alya immediately understood what was expected. Without needing to be commanded twice, with an almost synchronized movement, they turned around and bent over, each holding onto a different tree trunk.
Their positions formed an alluring curve, revealing their round, pale buttocks under the moonlight, offering themselves to the man who had impregnated them—a pair of blood sisters who were completely submissive.
Ren wasted no time. With a rough, lustful movement, he lowered his pants. Then, he approached Masha first. Without foreplay or gentleness, with one rough thrust, he inserted himself fully into Masha's already wet body.
*PLAP!*
"Ah~"
The sound of flesh colliding echoed loudly in the silence of the night, followed by Masha's stifled sigh. She clamped her hand over her mouth, her eyes wide with a mix of pain and pleasure. Her body was shaken violently by that first impact.
Ren did not give her time to adapt. He immediately started a fast and deep rhythm, each thrust full of force, making Masha's body sway helplessly.
*PLAP!* *PLAP!* *PLAP!* *PLAP!*
The sound of skin slapping and the rhythmic collision of bodies continued to resonate, muffled only by Masha's hushed hisses and groans which she tried hard to suppress. Her hands gripped the tree bark until her knuckles were white, holding back every impact that shook her entire body.
After a while of satisfying himself on Masha, Ren pulled out with a rough motion. Masha immediately went limp, leaning against the tree, breathless and trembling.
Ren then turned to Alya. This younger sister was even more sensitive.
*SCHLICK!*
A wet sound was heard as Ren entered Alya with one deep thrust.
"Hyaaa~"
Alya let out a small shriek which she immediately covered herself with her hand, her face flushed and her eyes teary. She was not used to such roughness, even after so long.
*PLAP!* *PLAP!* *PLAP!* *PLAP!*
Ren's rhythm was even faster and harder on Alya, as if he were punishing or marking something.
Every thrust felt like it wanted to penetrate all the way to her womb. Alya's more slender body was shaken violently, barely able to withstand the force behind it.
The sound of their hips colliding created a lewd rhythm that could only be heard by the three of them and perhaps by the trees around.
Ren switched back and forth between Masha and Alya several times, satisfying his lust on the two sisters without discrimination.
The sounds produced were a symphony of roughness: suppressed sighs, muffled groans, the sound of skin slapping against each other, and the continuous wet sounds each time Ren switched holes.
The climax finally came. With a low groan escaping his throat, Ren tightened his grip on Alya's hips—his last target—and released all his contents into her, trembling. Alya whimpered weakly, feeling the hot gush, her body limp and only supported by Ren's grip.
Ren pulled out, and without a word, did the same to Masha who was already waiting in the same position, giving her the same share.
