Shishio still remembered their bet on the sports exam (chapter 278), where Nana told him that she would do anything if he could gain the best result for the entire class. He had achieved the best result, but she hadn't given him his reward.
"So, can I ask anything?" Shishio asked curiously.
"U - um..." Nana nodded shyly with a blush since she noticed the change in Shishio's gaze.
"Even a perverted one?" Shishio asked as he observed Nana.
Nana didn't tie her hair into her usual hairstyle. Instead, she let her hair reach her back. Her blonde hair was wavy, and she wore light make-up on her face, showing that she had woken up earlier than now, so she could prepare herself.
Still, Nana didn't want to show it deliberately since she only wore shorts and a loose t-shirt.
Even so, Nana was still beautiful, especially when her white skin was shown through the gap of her loose t-shirt.
While Nana might be tanned, part of her body was white, especially inside the shirt.
Instantly, Shishio knew what kind of request he wanted to ask Nana.
Hearing Shishio's words, even though Nana was shy, she nodded. "Um." She might be quite bold, and her attack power was amazing, but her defense power was simply zero. Still, she was curious at what he was going to ask, "So what are you going to ask?"
"Can I put my head inside your t-shirt?" Shishio asked with a straight face.
"...What?" Nana was dumbfounded.
"Can I?" Shishio asked.
"Pervert!" Nana said with a blush.
"Didn't you say that I can ask anything, even a perverted one?" Shishio asked back.
"But... but..." Nana didn't expect that Shishio's request would be so perverted!
Nana thought that Shishio might ask for kissing or fondling her breasts since she knew that he often gazed into her breasts from time to time. While they might give her backache and often make her seem fat, she knew he loved them, so she was proud of them. However, she didn't expect his request to be so perverted and unique.
Still, Nana must admit that Shishio had always been faithful to his desires, and while he lied, he had never lied to his desires, and she didn't hate this part of him.
However, once again, Nana must admit that Shishio was a pervert!
"Can you?" Shishio asked as he hugged Nana tightly and rested his chin on her breasts.
"....." Nana looked at Shishio, who showed an expression of an abandoned puppy with watery eyes. She just couldn't look at him straight at this moment and could only sigh helplessly. "Okay, but if my t-shirt gets loose, take responsibility, okay?"
"Okay." Shishio nodded and said, "I'll take responsibility."
"Then do it." Nana was shy, but she was determined, so she pulled her t-shirt up slightly, showing her white stomach and purple bra.
Shishio was stunned for a moment since he knew that they were big from the outside, but it was his first time to see how big they were.
Also...
'It's so alluring...'
Her orchid-like scent was so nice as it spread into the room.
"Hu - hurry up!" Nana sounded quite nervous and even embarrassed when Shishio gazed into her body.
Shishio wasn't in a hurry and caressed her stomach.
"Hyaan~~!" Nana let out a moan before she slapped Shishio's hand directly with a red face. "Shishio!"
"Calm down," Shishio said calmly.
"But - but what if Onee-chan hears it?" Nana felt that she might not be able to meet her sister again if Ayaka saw what had happened here.
"Okay, I'll do it now." Shishio took a deep breath, trying to collect oxygen into his body since he was afraid that he might have difficulty breathing. He had to prepare well since he was about to start his venture on the two summits. While it wasn't his first time to do this since he often put his face between the breasts of his girlfriends, it was his first time to do it when his girlfriend was wearing clothes, so he would be lying if he wasn't nervous.
Shishio was afraid that he might have hypoxia since he would be trapped in a dark and narrow place. However, as a man, there was something that he would never back down, and so, he decided to move forward.
'Let's go!'
Shishio made up his mind and gently pressed his face against Nana's breasts!
"......."
Shishio couldn't say anything and felt that no words could describe his feeling since they were just too fantastic. While the bras might be an obstacle between him and the two summits in front of him, he also felt that it was akin to a guardrail that protected the one who visited the mountains, so they wouldn't fall into the valley.
Shishio knew that he couldn't be in a hurry, and he needed to do it slowly, or else he was afraid that he might become a beast.
Shishio felt that this system really disrupted him.
"Ho - how?" Nana asked nervously. "Why didn't you say anything."
"Sorry, it is just too amazing," Shishio said with a sigh.
Nana was speechless, but her naughty side suddenly awoke, and she asked, "Should I pull down my t-shirt now?"
"Okay." Shishio nodded, and he was ready for it.
Nana then pulled down her t-shirt and even covered Shishio with her t-shirt.
It was dark, hard to breathe, and narrow, but even so, it felt wonderful.
Shishio could feel as if he had returned to his mother's embrace somehow.
No, Shishio knew that his head was hugged by Nana right now.
"Nana?"
"Hmm?"
"What's wrong?" While Shishio might feel addicted by the feeling of her breasts, he pulled out her head and asked Nana since he was cornered about her state. "Did you hate it?"
"No, it is alright, but..." Nana was hesitant to talk.
Shishio hugged Nana, then carried her in his arms. He then opened the window door that was connected to the yard inside the living room.
When Shishio opened the door, the temperature from the outside entered the room, and it was pretty chilly.
"It's cold," Nana hugged Shishio's body back.
"Should I close it?" Shishio asked.
"No, let's just stay like this." Nana felt that the cold temperature could make her head sober.
Shishio then sat down with Nana and hugged his body like a big baby. He looked outside, watching the sun that slowly rose from the east, and softly called her name. "Nana."
"Hmm?"
"You know how strange our relationship is in the eyes of the people. I'm not a good boyfriend to you since I'm not only dating you alone, you're not my only girlfriend, and I almost let myself be seduced by your older sister," Shishio said.
"...You're pretty frank about it." Nana was speechless, especially when she heard the part Shishio was seduced by her older sister.
"Because I don't want to lie." Shishio patted Nana's back gently and said, "While being truthful to each other without lying to each other is hard, I'll try to be truthful to you as much as I can, even if the truth is ugly."
Shishio knew that his relationship with his many girlfriends was frowned upon.
Shishio could also tell that his girlfriends would be lying if they didn't feel sad, jealous, envious, or had many other feelings that might be bottled up inside their hearts because of how scumbag he was.
Even Shiina, who had said that she had accepted the rest, would be lying if she didn't feel sad or jealous when she knew him close to other girls.
However, they tolerated him because they loved him.
Shishio knew all of that, and he still became a scumbag. He knew that he had hurt them, and of course, he felt guilty about it. However, it was also a price for him to become a scumbag. He would bear this feeling until he died, but even so, he wouldn't regret his decision since even if his decision hurt them, he wouldn't say that his relationship was a mistake.
"So if you have something that you want to ask me, then ask." Shishio stared into Nana's eyes as he caressed her cheek. "I don't want you to bottle up your emotions after all."
Nana looked at Shishio for a moment and asked nervously, "Shishio, do you love me?"
"I love you," Shishio said without hesitation.
"....."
"What are you in a daze for? Isn't it obvious that I love you?" Shishio asked with a smile.
Nana stared at Shishio in a daze and felt that all the worries in her heart disappeared instantly. She might have eavesdropped on his conversation with Ayaka last night, and she also knew how her older sister bore a feeling toward her boyfriend.
Nana didn't feel that it was strange since she knew that this guy was charming. While his face was one thing, his personality was the one that attracted her the most since he had been truthful with what he wanted.
If Shishio wanted something, he wouldn't hesitate, and he would work hard to get it.
Similar to others, Nana might use his guilt so she could become his girlfriend, and she would be lying if she wasn't worried that he didn't love her, but his words erased all of her worries, and she knew that she could move to the new apartment next week.
"How much do you love me?" Nana asked cheerfully.
Shishio smiled and said, "It's more than yesterday and less than tomorrow."
Nana laughed happily and rubbed her face against his cheek.
"So, how about you? How much do you love me?" Shishio asked.
"I love you so much that I can let you date girls other than me," Nana said while staring at Shishio with a straight gaze.
"........"
Shishio could feel Nana's intense love somehow.
"You know what? There is something that I have always wanted to do, but I forgot to ask it," Shishio said.
"What?" Nana asked curiously, but then she looked at him in doubt. "It's not my breasts again, right?"
"......"
"No, it's this."
Shishio lifted Nana's chin then kissed her lips.
Nana opened her eyes wide before she recovered and gently hugged her arms around his neck affectionately.
They kept kissing each other while whispering the words of love together.
While they kissed, Shishio also knew that Ayaka was peeking at them, but he didn't mind and didn't pay attention to her since, in his eyes, there was only a Nana now.
---
After Shishio ate breakfast and took a bath, he decided to go back since he still had a promise that he needed to hold after this. Still, he didn't expect Golden Week to end so soon and felt that the time passed so fast with a happy time.
"I'll move to a new apartment next week. Help me, alright?" Nana said with a smile.
"Of course, I'll help you," Shishio said speechlessly.
"Wait a moment, I'll get you something," Nana suddenly said and left. "Onee-chan, talk with Shishio a bit."
"O - okay..." Ayaka was flustered then looked at Shisho shyly.
Shishio looked at Ayaka and held her hand gently. "Ayaka-nee."
"Ye - yes?" Ayaka didn't dare to look at him, but she still lifted her head a bit.
"I'm not sure where our relationship will lead, but I'll answer your feeling."
Shishio then pulled Ayaka's hand and used his other hand to hug her waist gently.
"Eh?" Ayaka blushed as their bodies pressed against each other.
"There's still time. You can push me away if you don't want to," Shishio said.
Ayaka was surprised, but then she made up her mind and said without hesitation, "No, I won't."
"You're not the only one, you know?"
"Let me see whether you're really as bad as I have heard, but I won't regret this since I have made my decision," Ayaka said without looking away from Shishio.
"Stupid, but... I won't you down."
Shishio then, without hesitation and kissed Ayaka's lips.
Ayaka closed her eyes and hugged his neck affectionately.
As they kissed, Shishio wondered whether he had become a good brother-in-law now.
