お兄ちゃんはおしまい！ raw 第01-10巻 [Onichan wa Oshimai vol 01-10]

Mahiro Oyama was just a normal erotic-game loving dude...until he woke up one morning as a woman! Turns out his mad-scientist little sister, Mihari, tried out one of her new experiments on him...with a disastrous outcome, as far as Mahiro's concerned! But Mihari is as determined to study him as he is determined to go back to his shut-in, game-playing life, and one thing's for sure...life is going to get a whole lot weirder from here on out!Original comic:https://www.pixiv.net/member_illust.php?id=159912
