Rei knew that she shouldn't do this. She should just quietly leave, pretending nothing had happened. Then, when it was over, she could just comfort her sister, yet she couldn't do it. The moment she heard Yuu's lewd voice behind the door, she was rooted in a place and unable to move.
As she listened to Yuu's voice, Rei could feel her body feel hotter and hotter as she became complicated and curious, wondering whether being held by him was so great.
Yet, Yuu, who was inside the room, couldn't pay attention to Rei since what was on her mind was only the new pleasure that her body felt at that moment.
Even though Mizuto and Yuu planned to go all out at this moment, he wasn't impatient, and he needed to make her wet enough, considering his size and all. Yuu's height wasn't tall, and she was relatively petite, so more preparation was needed to take her virginity.
However, for Yuu, she felt that this guy was too much!
"Oh~! Oh~! Mizuto~! Thi-This is too much~!"
While she tried to close her legs, Mizuto was between her legs, stopping her from closing them, licking her pink streak, and playing with her clitoris with his finger, causing her to be in a mess. Her voice, which is usually soft and gentle, became obscene and vulgar. It was filled with embarrassment, but at the same time, she was also a little scared as the pleasure that came from this act was much more than what he usually did to her.
Yet, as Yuu had given her everything to him, whether it was her heart or body, she couldn't say no, and her body also sought after this pleasure more.
"Hmnh~!"
In the end, her body shook violently as her hips raised, shaking several times and cum so many times.
On the other hand, while Mizuto wanted to put his penis inside her, he knew that he had to do it slowly. He couldn't be in a hurry and made sure that she was ready.
As Yuu breathed heavily, she lay on the bed, staring at him in a daze before readily accepting his kiss. Their kiss was lewd as they licked each other's tongues, inseparable while sucking each other's saliva.
This was something vulgar, something that might only be seen on hentai or porn, yet this happened before her.
Inside the room, Rei was sure that Mizuto was turning her little sister into a mess. Yet, no voice came out from her lips. Instead, her hand reached into her slender thighs, entering her panties that were so wet due to the sound that came out from her little sister.
Yet, this wasn't the end for Mizuto and Yuu.
Laying on the bed, Yuu looked at Mizuto, who had taken off his pants and put his glans over the surface of her pussy. She looked at him shyly and took a comforting sigh when his glans rubbed against her creamy pussy and clitoris.
Mizuto also wasn't much better since his penis was enveloped by pleasure.
"...can it enter?"
"You don't need to worry. Leave everything to me."
"Um."
The two drew their lips closer and started another kiss. Then, when they kissed, he pushed the glans of his penis inside her pussy.
Yuu was a virgin, so it definitely wasn't easy for him to enter, considering his size, too. Yet, due to his "Lover" job and how wet she was, her pussy swallowed his glans smoothly.
Even if his penis was covered in a condom, he could feel Yuu's inside was warm and soft. It was different from her mouth and hands. It was something that was clearly made to wrap his penis, giving it pleasure.
"Hmn..."
Yuu was slightly in pain, and she had a slightly distressed expression on her face. However, Mizuto could see the charm of a woman that slowly grew on her beautiful face.
"Your pussy is about to swallow my penis, Yuu..."
"D-Don't say something embarrassing...!"
While teasing this innocent girl with lewd words, Mizuto pushed his penis deeper inside. He pried open her pussy and penetrated her inside. Her vaginal walls tightened around his cock, and instead of pushing him, they pulled him inside, deeper and deeper, until he came to the deepest part of her pussy.
"Oh~!"
Yuu took another deep breath and looked at Mizuto with tears.
"We're connected, Yuu."
"Um."
As they had another kiss, Mizuto could feel how tight Yuu's pussy was. The way her vaginal walls tightened and squeezed his penis was just unbearable.
"Can you feel my shape inside you?"
"So-So big..."
Even so, Yuu could feel that Mizuto's cock perfectly fit inside her, and she sought him even further. Her pussy also became so wet that it drenched onto her bed, and the scent of the sex was just so intense inside the room.
While it was pain at first, she could feel a sense of joy and excitement that grew when his cock was connected inside her pussy.
Her expression, which was full of agony at first, gradually became lewd, and she also let out a sweet voice.
Her pussy, which was unfamiliar with his cock, had become accustomed, and she enjoyed the feeling of being pounded by him.
The sound of her bed creaking echoed throughout the room.
The image of him slamming his hips against her body was clearly reflected in the mirror inside her room.
The sight of his large cock moving in and out on his friend's pussy.
Everything about this was so naughty and lewd that it couldn't be described by a mere word.
This is sex.
It was on a different level than what they had previously done together. It was something more and something dirty, yet sacred at the same time.
"Oh~! Hmn~! Too much~! Mizuto~! Mizuto~!"
Unlike before, this time, Yuu was afraid that she would fall even deeper. The pleasure was even more intense than before, and she could only cry as she clung to him tightly as his penis moved in and out inside her pussy.
The unfamiliar feelings became familiar.
This feeling was too much~!
Yuu felt that her consciousness became so hazy and she felt like she was floating on the clouds before her body shivered. Yet, this wasn't the end, even if she cum, and he stopped for a while, the act of sex between them hadn't stopped.
It wouldn't be finished until he came.
Or until he was satisfied.
Inside her room, where they were completely naked, rubbing their genitals against each other, feeling the enjoyment of sex.
"I am going to cum, Yuu!"
Hearing his words, even if Yuu was in a daze due to the pleasure, she clung to him even tighter. Then, at that moment, Mizuto poured all of his semen inside the condom, causing her to grip the bed sheets tightly as her nice-sized breasts shook violently. Her voice was so harsh, yet it contained the sweetness and lewdness that one couldn't imagine would come from her.
As he ejaculated, he hugged her small body tightly until he released all of his semen inside the condom.
While Yuu breathed heavily and sweated all over her body, she smiled, feeling satisfied that she could satisfy him.
Watching this smile, Mizuto had to say this friend of his was really lewd.
The two smiled and started another kiss before he changed his condom, ready for another round, causing Rei, who was outside the room in a mess, to wonder when they were going to stop.
