Shishio is a good brother-in-law 4

Hearing the soft yet alluring voice from Ayaka, Shishio's mind was shaken for a moment.

Without a doubt, Ayaka was a charming woman, and she was one of the most beautiful women that Shishio had seen in his life, but more importantly, she might be one with the biggest size he had seen in his life.

Why did he add "might"?

While Shishio was living in this world, it didn't mean that he had seen how vast the world was, so there might be someone out there who had a bigger size than Ayaka.

However, among his acquaintances, Ayaka was the biggest one, without a doubt.

If it was before, Shishio might have trouble whether he should become a good brother-in-law or a bad brother-in-law, but when he smelled an aroma of alcohol that became closer and closer toward his lips, he stopped Ayaka by lifting her body.

"....."

Ayaka blinked her eyes and felt confused at why the distance between them suddenly became far. However, she understood everything and asked with a lonely voice, "Do you hate me?"

Shishio glanced at Nana, who was sleeping on his lap soundly and even rubbed her face against his stomach, feeling speechless.

Your boyfriend was seduced by your older sister, but how could you sleep so soundly?

Still, it was a good thing that Nana was sleeping since Shishio was afraid the thing he might talk about wasn't suitable to be heard by Nana right now.

However, if they could accept each other, it would be different.

"I don't hate you, and I don't mind kissing you..." Shishio told the truth since who didn't want to kiss someone as beautiful as Ayaka?

Shishio was just a normal scumbag, and of course, he was attracted by Ayaka's charm.

"Then..."

There was no barrier or an obstacle between them, especially when Nana was sleeping, so Ayaka was about to kiss him again, but a hand pressed against her forehead.

"I don't mind if we kiss each other, but let's not do it when you're drunk."

It might be part of his pride as a scumbag that Shishio didn't want to do anything weird to someone drunk, even if that woman or girl might be the most beautiful in the world.

It sounded stupid since Shishio had become a scumbag, so there was no need to hesitate anymore. He could just kiss Ayaka then bring her to the room, having a good time together, but if she was sober.

If Ayaka was drunk, then it was a different matter.

While some people thought that alcohol was a good thing and felt it was cool to drink it, Shishio didn't think so.

Shishio might have drunk it in the past, but he only drank a small amount since drinking a lot of alcohol would numb his brain and make his head work slowly. Also, it might make people forget what had happened.

After they kissed, Shishio didn't want Ayaka to pretend that nothing had happened between them since he wanted to develop a deeper relationship with her.

While Ayaka might be drunk, her consciousness was still there, and she understood Shishio's meaning. She pouted and leaned on his chest, trying to find a comfortable position, before she said, "You're not a good man, Shishio-kun."

"You're not a good older sister either," Shishio said speechlessly as he felt he had been seduced whether the first time they met each other until now.

Ayaka was stunned, but then she laughed and kissed Shishio's cheek.

Shishio didn't stop Ayaka and patted Ayaka's back gently and said, "You're drunk. You should sleep."

"Okay." Ayaka nodded, then said, "But carry me."

"...."

Shishio looked at Ayaka for a moment, carried Ayaka on his arm, and used his other arm to carry Nana, who slobbered on his shoulder.

The string of liquid dripped from the corner of Nana's mouth, giving her a stupidly cute charm that seldom appeared.

Shishio thought that Nana was cute, but Ayaka was alluring.

Ayaka smiled when Shishio carried her and Nana together while wondering whether he had planned to get two sisters together. While she might be lying if such a possibility didn't cross her mind, because of the effect of the alcohol, she became bolder and hugged his head, pressing it against her chest.

"You like this, right?"

"...Er."

Even a deity could get angry. Shishio, just a normal human with a system, also reacted when Ayaka pressed her breasts against his face. They were so soft and smelled so nice, but it was hard to breathe with two large masses that covered his face. Luckily, one of his eyes wasn't covered, and he could see his surroundings.

"Shishio-kun, can you walk over there? Let me turn off the light first," Ayaka said as she kept pressing her chest against Shishio's face.

Shishio was speechless, but he followed her words and let her turn off the light before he walked in the direction of Ayaka's room.

Shishio pulled out his head slightly, but Ayaka kept hugging him tightly. He was helpless and asked, "What are you planning to do, Ayaka-nee?"

"What are you planning to do if Nana is living in the apartment alone?" Ayaka asked back.

"I don't have a plan," Shishi said naturally.

"Really?" Ayaka asked with doubt, and clearly, the effect of the alcohol seemed to have disappeared from her head.

"However, we're lovers, so naturally, something might happen between us," Shishio said calmly.

Ayaka wanted to say something, but no words came out of her mouth.

"Can you open the door? My hands are preoccupied," Shishio said.

Ayaka nodded and opened the door of her room slowly.

Shishio didn't have any strange feelings or whatever. He entered and walked into her body, placing Nana gently on the bed, letting her lay there to sleep.

However, as Nana lay on the bed, she hugged his arm tightly, pressing it against her two masses with a stupid smile.

Shishio looked at Nana helplessly and reluctantly took out his arm from her two masses.

Nana seemed uncomfortable, and her hands moved around as if she was trying to reach something.

Shishio caressed Nana's soft cheek gently, which caused her to smile and dripped another saliva from the corner of her mouth.

"...."

"She's so happy," Shishio said speechlessly.

"Yeah, she doesn't know that her boyfriend is a bad guy who is happy being seduced by her older sister," Ayaka also added.

"....."

Shishio glanced at Ayaka for a moment and wasn't sure what to say for a moment since he wasn't exactly a good guy either, and Nana knew that fact. However, Ayaka didn't know that fact, but when he considered their relationship, he felt it was better to keep this matter until later since he was tired.

"Your head must be dizzy now because of the alcohol. You should go sleep." Shishio also placed Ayaka on the other side of the bed and was about to go out, but his wrist was held.

"Where are you going?" Ayaka asked.

"I'm going to sleep on the sofa," Shishio said.

"But..." Ayaka wanted to stop Shishio.

However, Shishio didn't really want to stay any longer since something might happen, and they might do something sorry to Nana if they really stayed together.

"Well, I'll go out now." Shishio was about to walk out of Ayaka's room, but Ayaka pulled out his wrist.

Shishio might not lose his balance because of the sudden force that pulled him, but he deliberately fell since he fell on the top of the two softest things. His head was right on the top of Ayaka's masses, and he wanted to rub his face there somehow, but he knew that this wasn't the time for this since there was something that they must settle.

Ayaka wanted to kiss him again, but Shishio flicked her forehead, making her pout.

"Next time, not now," Shishio said, then left since he didn't want to kiss her right now. Not when she was drunk.

Ayaka looked at Shishio's back before she let out a sigh. She then looked at Nana, who slept so soundly and couldn't help but pull her soft cheek.

"Fuweh...?"

Nana was confused and showed an uncomfortable expression on her sleeping face.

"I feel so jealous of you..." Ayaka sighed before she slept with her sister with a smile, thinking that their sisterhood would develop further in another sense in the future.

Shishio was sleeping on the sofa, without any blanket or a pillow in the living room. The night of the spring was quite cold. Fortunately, his body was naturally strong, so there was nothing to worry about.

However, Shishio must admit that it was quite uncomfortable, not because of the sofa or the temperature but because his body was burning. He could still remember how soft Ayaka's body was, and he knew that he could get her there, but by doing that, he knew that Ayaka would be trapped in a guilty feeling.

So Shishio could only endure since everything needed a process.

Still, Ayaka was an adult instead of a child, so she could naturally take responsibility for what she had done.

However, the main problem wasn't this.

The two of them knew the main problem.

While they knew that it was exciting, and they knew that it would feel nice, it wouldn't be good for Nana.

It wouldn't be too late after Shishio might talk about this problem with Nana, but he hadn't deepened his relationship with Nana, so he needed to do it gently and slowly, so his ships wouldn't be capsized because of an unexpected wave.

---

Shishio wasn't sure when he fell asleep, but he slept quite comfortably until he felt something heavy on his stomach.

"Ugh!"

Shishio almost couldn't breathe when his solar plexus was hit with a heavy mass. He coughed and opened his eyes unhappily. "Nana..."

Nana straddled his stomach with a happy smile since it seemed that she had succeeded in giving him a prank, but when she saw his painful expression, she felt sorry and apologized. "Sorry, are you alright?" She felt that she was too much with her prank.

Shishio wanted to say that Nana had gained some weight, but he didn't say anything since her appearance was still good and her slightly chubby body also wasn't bad.

"...What time is it?"

Shishio didn't see the sun through the gap of the curtain, so he felt curious at what time right now.

"It should be five in the morning," Nana said subconsciously.

"Huh? Why did you wake up so early?" Shishio was dumbfounded.

"Isn't it because of Onee-chan? She kissed me so suddenly!" Nana pouted when she thought her lips were kissed by Ayaka!

"You weren't good with alcohol?" Shishio sighed as he patted Nana's head.

"Well, I'm not good at it." Nana also leaned forward and let her entire body rest on Shishio's body.

"Don't do this. Something on me might wake up," Shishio said with a sigh.

"Something?" Nana was confused until she felt something hard and big between her butts. Her face flushed as she looked at him shyly. "Pervert."

"....."

"By the way, Shishio."

"Hmm?"

"Remember before?"

"Before?"

"I promised to do anything that you requested from me, right? Don't you have something to ask me? I'll do anything now," Nana said with a smile, but this smile was unlike her previous happy and teasing smile. Her smile was full of allure. It was the smile of a woman who wanted to seduce the man that she loved.

"..."

Shishio thought that this must be his reward for being a good brother-in-law.
