Two schoolgirls getting kidnapped on a trip to China.

This was a really dark story that I'm trying to find again as I'm hoping more chapters have been released (only two were out at the time). Starts with two Japanese schoolgirls getting kidnapped in China. They get taken to a farm of sorts and get gangraped. Second chapter we learn more about the kidnappers, and turns out that they make some sort of alcohol, whiskey if I recall correctly. It's gotten pretty popular, but it also turns out that they make it by forcing women they kidnap into the barrels full of whiskey and letting them disolve in it (like I said, real damn dark). At the end of the chapter one girl had been forced into a barrel and the other had managed to escape, coming across some Chinese soldiers and thinking she is safe. Unfortunately for her the soldiers has no plans on getting her home, planning to rape her and maybe even send her back to the kidnappers.

The story stuck with me, and I've been trying to find it again without any luck. Been hoping for more chapters, hopefully ones where things turn out alright for the poor girls. If anyone could help me find it I'd very much appreciate it. Thanks!
