Miki, a pretty and popular girl, makes her older brother pretend to be her boyfriend. To make the act more convincing, she takes him to a love hotel, where she attempts to seduce him.
Her design reminds me of Kirino, except with tanned skin and a very developed body.

Once in a while, a switch from “Aniki” to “Onii-chan” is fine, too.
It was too short;/ Thanks ^^
Yeah, it’s a pity Warabino Matsuri rarely does full length chapter stuff.
Thanks for the share!
