The solo masturbation technique which entails lying on your back with your ass in an elevated position in relation to your head, and proceeding to ejaculate onto ones stomach and allowing the semen to percolate and slowly slide down their chest into their eagerly awaiting windpipe. This technique then can also be combined with the spurting motorboat technique, which is the act of spraying semen all over yourself while making a motorboat action.
Dude did you hear about Bogart? His mom found him in his room solo-reversed-doggie-style, covered in jizz after he drowned himself performing a colorado avalanche. I think he died choking while trying to bathe himself with a spurting motorboat hosedown.
