This is when a girl is hogtied or frogtied, preferably with a ballgag, and you stick a vibrator or some other stimulating sex toy into her vagina and turn it on. The pleasure will make her orgasm, forming a Volcanic Milky Blossum.
When having BDMS with Sara, Robert frogtied her and gave her a Volcanic Milky Blossum. She was exposed with her clothes off and naked and Robert jacked off to the sight of her helplessness.
