A story of two emotionally unhealthy people doing sexy stuff. Ill-written, but overall an intruiging story if you use your suspension of disbelief. Defenitely not a good example of a healthy relationship though, with or without the kink.
The kinky stuff they did was pretty tame as far as kink goes. Had expected more edgy stuff from all the hubbub. Turns out the real edgy stuff was just the abusive relationship described in these pages.
