I'm not clear on what you mean by g. Usually g refers to the acceleration due to gravity. The value of g is independent of the mass of the body. If you simply mean acceleration and its due to something other than gravity then increasing the mass will decrease the acceleration. Simply solve for a to get

a = F/m

Therefore increase m causes a decrease in a.
