Synopsis
“Today was such a great day… I never knew it could feel that good…♪”
What comes to mind is when I seduced my sister’s boyfriend. Given that my sister is fastidious, he’s a really likable guy.
…Though he’s a bit weak to pressure.
But that works perfectly in my favor. (I’ve always wanted what belongs to my sister…♪)
I’ve been like this since childhood. My sister is really lenient with me too, and gives me whatever I ask for. But I doubt she’d give me her boyfriend…
Even if my sister said it was okay, the other person would have to agree, right?
(…Hmm, our sexual chemistry seems really good though…)
Onii-san was moving his hips voluntarily partway through too, so he was enjoying it, right? If I could make him addicted to having sex with me, then maybe…
(When will I see Onii-san next?)
Thinking such things, I spent the night in an excited mood.
