Stuffing

Absolutely!!! When you stuff your self your gradually expand your stomach. so when it starts to digest, you feel hungrier sooner.

there are also numerous hormonal changes that take place with overeating, and this is one of the factors that causes increased hunger with increased eating. the increased volume of your stomach is probably part of the equation as previous posts have stated, but it is rather complex and is also dependent on your cortisol and insulin levels after a big meal.
