storage mod idea.
breast size for aida increase by storing drinkable liquid or semen
big belly instead
or buttcheeks increase instead
and upgrade benis module for larger individuals
benis gets bigger so you can use it on targets larger than aida.
the balls also can act as a storage unit so they can get bigger.
Mouth mod for mouth related things
or
disguise mod human looking head
Sorry if I offend you but I kept thinking about these thing when I played your game Paccsu
