Improvised explosive device

[Justin Bieber]

When a guy knows that he is about to get a blowjob from a girl he doesnt like, and has [adequate] time to prepare, he can masturbate just to the point of ejaculation. Then, the man would have the woman get on her knees while she takes off his pants. If executed correctly, once the woman [reveals] his member and takes hold, he will cum in her face, causing her to be left very messy and surprised... [Allah Akbar]!
