Tanabe Yuuka no Dokuhaku

Yuuka Tanabe is just your average housewife - she settled down with her high school bestie after they both graduated, creating a lovely little family together. Everything's been hunky-dory for them ever since! But then there comes this one particularly fucked up day when dear ol' hubby happens to be out at work and some random motherfucker shows the fuck up to their place. This dude decides that he wants to take what ain't his, so he breaks in and forces himself on poor Yuuka, shattering her peaceful existence forever...
