Nina is possessed of a fair amount of self-conscious awkwardness, a great deal of hotness, and excellent pain-processing abilities. We take advantage of all three of those with some naked hopscotch with clothespins on their nipples. I think one of the keys to BDSM is creating internal conflict. Making someone do something uncomfortable and vulnerable-looking is an underrated way to poke at that (especially if it’s already a button for them). As supporting evidence, I would like to point at a moment about three and a half minutes into this. If you go to 3:30 and pause the video, then play it very slowly through about the next two seconds, you will see precisely what I mean. Speaking of slowed-down playback; I didn't tack any slow-mo footage on the end this time, but don't miss the opportunity to watch their (great) tits bouncing that way. The video is 60 progressive frames a second, which looks fabulous played back at a lower framerate. My preferred porn-watching tool is 'nPlayer' on an iPad, it's got great gestural controls including playback speed. VLC has a simple slider, QuickTime Player will do it if you hold down 'K' then 'L' (or 'J' for backwards), I dunno about Windows Media Player or Android devices.
