Kanojo no Imouto no Kyonyuu Yuuwaku ~Onii-chan, Watashi to Ii Koto Shimashou?

“Ah, today was a great day, wasn’t it… I felt so good… ♪”

What I’m remembering is the time I tempted my sister’s boyfriend.

My sister, who’s usually so clean and proper, only does it with her boyfriend, and she’s a person who’s hard to get close to.

…But she has a slightly weak point, though.

And that’s exactly what’s convenient for me.

(My sister’s things, I just can’t help but want them… ♪)

I’ve been like this since I was little.

My sister is really sweet to me, so she gives in to my wants.

But, of course, she wouldn’t give me her boyfriend, no matter what…

Even if my sister says it’s okay, if the other person doesn’t agree, it’s no good.

(…Hmm, it seems like our erotic compatibility is pretty good, though…)

You, too, started moving your hips halfway through and enjoyed it, didn’t you?

If I can make you my erotic prisoner, maybe…

(When will I get to meet you again, big brother?)

Thinking these things, I spent the night in a fluttery mood.
