Otome no Dori story

Guy loves his imouto and his childhood friend
Imouto gets raped by filthy old men repeatedly
Imouto hates oniichan for not realizing that something was wrong, and for liking his childhood friend more than her
Imouto calls the old men and gets them to rape his childhood friend
They take videos of it
Send the videos to the guy
The first time, she hates it, and cries that she wanted to give her virginity to the protagonist
Typical beta Japanese faggot protagonist says nothing to her the next day even though she is visibly upset
Keep raping her
Keep sending videos to the guy
Beta extraordinaire just keeps fapping to the vids of the girl he wanted to marry getting fucked senseless by old men

MC discovers imouto slutting herself up to old men
She explains what she did
They fuck

Unexplained time skip
They have a baby together (lol, not his kid, it's god knows which of the old men)
Guy has somehow forgotten about all of this, thinks it was a bad dream
Finds another video of wifey fucking the fat old men
She even says she'll bring the kid over to fuck when she's old enough
They come home, and he's still fucking acting like nothing is happening

That's as far as I could stand to read. Fucking stupid.
