Also suggestive scenes.
Proposal: it would also be useful to test the effects of a dental water jet. A great product that is used for dental hygiene, but can also be used for other purposes. A device as Jet Waterpik Ultra Handy does not need the tube connected to a fixed tank. Stimulation of the jet on the clitoris or G-spot inside the area could give very stimulating effects. I do not know whether pleasure or torture, but I think both.
Everything OK. lacking, however, new fantasies. Okay vibrator, but it's a little too used in many scenes. For example you could use, or use a brush to use as the Japanese. The bristles of the brush are very stimulating the clitoris. It can become a pleasant torture.
Very beautiful scenes. But you could also make a quantum leap. For example, with a master and a mistress or three masters men and women. With two men and a woman is perhaps the best solution. Or a mixed couple of masters and slaves, 1 or 2.
