Since you're asking for feedback I'll post my thoughts so far.

From a technical perspective the writing is very solid: I didn't notice any grammatical or spelling errors, everything is described well and everything seems realistic (or as realistic as a story in this genre can be, anyway).

When it comes to the subject matter, though, I can't help but notice a certain lack of variety. The most recent chapter marks the fourth time in a row somebody has lost the use of two or more of their limbs against their will. Granted, the details vary a little each time, but effectively they all boil down to the same thing. Now if that's your fetish that's fine, but personally I would advise you to mix it up a little more to keep things from getting stale.

Aside from that point the quality of the writing is certainly there, though, so keep it up.
