Improvised Explosive Device

When a guy knows that he is about to get a blowjob from a girl he doesn't 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!

A slut comes over thinking she's going to get to suck some dick. To her surprise, she is about to be booby trapped. Once she gets the dick out, it explodes in her face like a roadside bomb, also known as an IED, or Improvised Explosive Device.
