I've had some incredibly busy days, so I'm kinda late to the party. Well done with the latest chapter! I was going to give you some critique but then you did it yourself, writing pretty much exactly what I was going to comment. I'll sum my thoughts up for you though.

I too missed more details about what was going on in Christi's head during her last moments, being in pure, hopeless agony with her naked sister on top of her. The last thing the poor girl experienced was her sister pissing, shitting and spilling her guts in her face along with her own excruciating pain. I think that part could be fleshed out a bit more.

The chapter as a whole is still really good. The hunt is exciting to read, especially the part where Lauren tries to negotiate for her sisters' lives. The rape was a bit too quick for my tastes though. A standard rape is boring in this context, but I think Bob could have hurt her a little more, maybe sacrificed a breast for each of her sisters, idk.

To summarize this is excellent writing per usual, but some parts are a little bare and could use some more detail. I'm looking forward to the next chapter.
