Before plunging into the cruel world of Impact play, I suggest you learn more about safety. It is absolutely necessary to avoid certain areas on the body because even light blows and slaps can simply make your partner disabled! We are talking about serious damage to their joints and bones, as well as nerve endings. This is no longer just pain, but a real danger to life and health. Therefore, I always recommend getting acquainted with the theory first and only then proceeding to practice.
By the way, on the watch.fetishes.cam you will find good teachers who can show you, and will also be happy to demonstrate to their slaves what Impact play is.
So, you need to avoid the zones:
the neck on both sides;
the ears and eyes;
the joints on arms and legs;
the lower back, the coccyx;
area of the heart.
Also, if you are not sure of your technique, you should not hit the kidneys, as well as the genitals. The remaining points can be considered not so important, but still essential. Before starting Impact play, you can discuss whether your partner can hit you in the face, leaving bruises. I also want to remind you that experience and the ability to rely on your partner are very important here. Then this is really a BDSM practitioner, they are a stupid beating.
