Steam Geyser

A sex act which involves a man defecating into a woman's mouth, then lying on his back while the woman then vomits directly onto his penis, forming a mound-like structure, not unlike naturally occurring geysers, around the base of aforementioned penis. The man then manipulates his own prostate, causing him to spray ejaculate into the woman's eyes.
