[Ao]

Still, he didn't just continue his time to corrupt Chitoge. A week later, he decided to take Kosaki and Haru's first time. 

…

Lunchbreak on the rooftop. Kosaki, Haru, and Tsugumi are eating with him.

"Can we become one now, Kosaki… Haru?

He look at them as he said their names. Tsugumi who knows what he meant suddenly heavily sigh.

"I'm gonna go to the toilet."

She decided not to pry on the sister's decision. After all, she knows that this is something that they undoubtedly will do with him.

She sighs inwardly.

'He is really a sinner but I truly love this man. Haaah… be grateful that you have a girlfriend like me, Ao.'

And she goes to the school.

"Uhmm… "

After telling them what he wanted, Kosaki and Haru suddenly distance their selves and talk about their decision.

"So…uhmm…"

"But I want to do it alone with him, Onee-chan."

"I, too but…"

{It's okay to do with him now and also were sisters so it is not weird to do together with him.} 

"…I think that I will agree, Haru."

"But…"

{I agree}

"…if it's okay with you then… I will agree too."

After their short meeting, they go back to his position and say their decision. 

"We agree…" 

They said at the same time as their face are now red as a beetroot.

…

The sky sun was about to set as they walk into Onodera's residence. He wanted to do it with them in his home since he wanted to let Chitoge peek with them so that she will feel more empty whenever she masturbated however, Kosaki and Haru reject him.

"…It's just… we are not used to that kind of luxurious place like yours."

This is their reason why.

In the end, he agrees with them to do it in their house. Another reason is, that their mother is in the neighborhood assembly until 10 so they solo their house right now.

Arriving at their residence, they didn't immediately do it and started to eat first. After all, you can't fight a war, especially bed war, if your stomach is not full.

"Mmmm~ Your curry, Kosaki, is delicious!"

"Umu! Onee-chan after all train every day with me! Although... at first, I wanted to surrender but…"

Haru wipe her tear and said, "…all of my hard work for those days to help her have now a fruit!"

"Hey! You making me look like I'm bad at cooking, Haru!"

"But that's the tru—"

Kosaki blocks her mouth with her both hands.

"Stop it! Don't say more!"

"Hahaha…"

Ao who saw this laughed lightly as they continue this lively dinner.

…

In the Mansion. 

Tsugumi is now with Chitoge. She brushes her hair while they talking about something she knows that she needs to talk with her.

"You're now Ao's girlfriend, right?"

There is a melancholic tone in her voice that causes her to stop brushing her hair. 

Silence began to rise for some seconds and broke until she give her answer.

"Yes… howev—"

As she was about to say about she is not the only one, Chitoge suddenly stand up and face her.

Tears started to drop in her eyes as she sadly said, "Can you please break up with him?"
