One male of heterosexual persuasion ejaculates his seed upon an unsuspecting male who is also of heterosexual persuasion. This typically occurs to the unsuspecting male (Kiepee) while he is asleep by the ejaculating male (Kieper). Although in rare circumstances the Kieper is creative enough to ejaculate his seed upon the still unsuspecting Kiepee while both parties are awake.
