I saw images/videos on the net where a woman's clitoris is spanked with hand or some device. I tried it with my mazo patient in several ways, but we found it the most interesting with a thin wooden cane. I opened her labia with clamps, and stroked directly to her clit. I did not stroked hard, it was rather uncomfortable than painful, but after several strokes she started crying because of the throbbing pain in her clit.
After she calmed down, she told me that it was not hard in the first few minutes, but slowly the hole area started throbbing and at the end, it was like a bee sting or something similar.
Anyone tried this?
