Невероятный сеанс не до оргазма

Incredible edging session. I have used 5 cockrings with vibrators on his cock and balls. His whole manhood is vibrating, it makes him crazy but not enough to cum. His cock just pumps precum fluid all the time as he stay on the edge and can't cum. This is awesome view but I have to help him cum eventually and he shoot an enormous amount of sperm in high pressure blasts.
