- the descriptions of pain/pleasure switch and trance states ( in my own experience this is the most intriguing, rewarding and scary part of any S/M - as opposed to D/S relationship)
- the allusions to De Sade and Masoch (ritualised repetitive proceedings and the switch from telling a story to acting it out in more and more extreme ways) I don't know whether they were intentional, but they kept me very happy.
