Loved it! Mark was as cool as he is at his best and Holly was great. Her shapely muscular body, particularly her legs, is very exciting. The tats are are awful, of course. A bit more flogging would have been good, but perhaps next time, and I hope that's soon.
Sorry, I just found the story pointless, and the scenes unexciting. Thinking about why that should be so, I suppose is that with the story of a totally compliant subject, effectively there is no submission at all.
