When perfoming a sexual act, before the male cums inside the woman, he needs to pull out and driect the ejaculation at the womans eyes. Once the woman becomes blinded by the warm sticky load the male slaps the woman around the face for a short period of time. Once this is done he lays her back and tells her to open her mouth, now because she can't see she doesnt know wats going into her mouth. The male pretends tht he's inserting his dick when really he shits into her mouth. This is called Boom Shang Wallyy.
