A form of assisted masturbation for a female during which she grabs her male partner's index finger (he may retract the other fingers of that hand into a fist) and uses it to penetrate herself and rub her clitoris for as long as is necessary for her to cum. It is crucial that the male partner be entirely passive, except for keeping his finger rigid and straight, in the form of a missile. A variant of the guided missile is the full first strike, which entails the use of 3 or more fingers.
After an hour of eating her out without success, I suggested a guided missile, which finally got her off.
