"Apparently, our parents are opening a shop together, so Niina-chan will be coming over on weekends.

She seemed bored, so I suggested a bunch of ways to pass the time, but nothing seemed to interest her.

'Not into games… What about shogi? No? Then, uh—'

*'…Wanna just do something lewd instead?'*

*'Huh?!'*

*'Well, there’s nothing else to do. And we are… a guy and a girl, after all.'*

*'B-But, Niina, you’re still a (middle/high) school student, right?'*

*'I… don’t mind. But yeah, I am a (middle/high) schooler.'*

*'…So, Onii-chan’s a lolicon?'*

*'I-If you hate the idea, forget it! I just… suggested it because Niina-chan is my type, so I thought I’d try my luck.'*

*'…Heh. Fine.'*

And so began our secret, naughty weekends—full of teasing, hidden from our parents.
