I only tried this machine once, it is a bit tricky to get it right. I decided to test it again, this time with Darina Nikitina, who is literally up for anything. She controls the machine herself, the machine can go from level 1 (almost no spank) to 10 (a devastating blow). Above level 5, everything is already very painful with the wooden ruler I have attached to it. Darina had a lot of fun playing with the machine, but at the end she spanked herself so hard she had a red butt for a long time. I will definitely use this machine more, I love machines and bondage! If you have any ideas for setups, please comment below!
