Real S/M, no filler.
Master Len is a silver-haired fox of a dom, in charge of disciplining two naughty girls, Bethany and Penny. He starts off with Bethany, who was sent home from school for wearing her skirt too short. Obviously, she deserves an over-the-knee spanking. When that's not enough, she's tied over the baseboard and spanked some more, although we only get to see her distressed face in the mirror, not the blows as they land. Master Len then takes her down to the dungeon and tickles her mercilessly. It's a rough transition from the playfulness of that segment to the next scene, where Len takes a bullwhip to Bethany's tender flesh as she writhes, hands secured to the ceiling.
Penny is another schoolgirl, already blindfolded and in bondage, when we meet her. She's whisked off to the dungeon and forced to her hands, legs spread, in an open-bottomed cage, while Len flogs her cunt. Some extreme suspension bondage follows as she is hoisted into the air by her waist, body bending into an arc. More corporeal torments follow as she's gagged and flogged until she comes.
This video suffers from a lot of wasted potential. The after-scene interviews are a great idea and should be continued. Master Len manages to be stern without being creepy. But the editing is rough, and worse, the segments are too short! Nothing is allowed to develop. The participants are obviously having a good time, but the viewer isn't allowed to share the fun. And that's a shame.
