This game features scenes where a character's belly is inflated during sexual play. This could be due to the excessive amounts of foreign material (liquids, gasses, monster eggs etc.) introduced to the body or the insertion of over-sized objects (a huge penis, a mass of tentacles or slimes, etc.) through any orifice. It can be consensual or forced.

Can be used together with Huge Insertion if it results in Stomach Deformation.
