Anus training for me is just a routine. I stretch and strengthen it to get maximum pleasure from anal sex. I can take a large objects, but at the same time hold the needle ) All this thanks to the training with inflatable buttplugs. On the basis of which I created my HVCOACH device. I also strengthen the vaginal muscles with kegel exercises. The first version was with a small latex balloon. I could compress it with a force of up to 2 atmospheres. Can you imagine what I can do with a cock after such a workout? watch my videos ))
