Uchi no Jimi na Imouto ga, Konna ni Kyonyuu de Erokatta Nante! ~Nuretara Nureru Hatsujou Switch~ (ウチの地味な妹が、こんなに巨乳でエロかったなんて! ~濡れたらヌレる発情スイッチ~, Official Homepage) is an upcoming visual novel from Appetite, to be released 2014-08-22.
The protagonist, Chisato, has a younger sister, Chimi. One day, he hears her cry out at school. He rushes to her aid to find that someone has accidentally spilled a bucket of water on her. She’s soaked, and she suddenly rushes off.
Chisato meets Chimi on the way home. She has changed clothes, and seems to be back to normal. On the way home, though, she is splashed over and over again. Bad luck.
When they finally get home, Chisato intends to send Chimi to take a shower, but she can’t take it anymore: she drops to her knees and begins to masturbate, right in front of Chisato. Chisato is shocked, and doesn’t understand why she’s doing this.
Their mother arrives home, which seems to snap Chimi out of it, so Chisato hurries her into the shower before anything else can happen. The spray of the shower is too much for Chimi, though, and she pushes her brother down and fucks him on the spot.
The next day, Chimi has gone to school ahead of Chisato, who is still uncertain about the events of the previous day. When it’s time for gym class–swimming lessons–Chimi pulls him into the locker room and, depending on the player’s choice, Chisato either fucks her or eats her out.
End of trial.
The premise of this one, as the title says, is that when Chimi gets wet, she really gets wet. There’s your awful pun for the day. This game has ‘nukige’ written all over it (as though Appetite makes anything else). The concept is somewhat amusing–at least it’s better than the usual no-excuse-offered nukige.
The game is coming out in a few weeks. Until then, you can download the trial to get a taste of the game.
