When your whore girlfriend is sucking you off and and you say your gonna cum and she points your dick directly at your face or upper body and you cum shot yourself. This can also happen during masturbation, hand job or sex.
During a sexual act, more then two people. Such as a threesome or an orgy. When one man or more is accidently hit with another man’s semen while they are attempting to ejaculate on someone else or pulling out. Protocol reaction for the person who was shot is to quickly wipe it off and not bring attention to it.
During an orgy my buddy accidently got hit with some friendly fire.
