The grenade is an alternative sexual manuaveur, it begins with the basic handjob. When the man begins to orgasm however is where the grenade differs because the one handjobbing makes a fist around the erect member and clamps their thumb over the penile orfice. This is usually followed by a yelp by the man because of building pressure and is usually released quickly with a explosion of white male secretion.
