Angus handshake

For a man to perform an Angus handshake, he must begin by being on the bottom, in the 69 position with a woman. Just before ejaculation, the man tucks the woman's hair under his ass, preventing the woman from being able to remove her mouth from the man's penis. At the moment of ejaculation, the man squeezes out a good fart, and thrusts two fingers into the woman's ass. The glorious resulting gasp from having two fingers unexpectedly jammed in her ass causes a unique gagging on both semen and the vicious fart that accompanies it. The effect is compounded by the fact that she cannot remove her face from the area.
