[Kariumu] Giant Couple [Full Color]

A colossal sister wakes from her nap sprawled across a city, and when her little brother Yu-kun loses their bet, his promised prize is getting to do something lewd with his onee-chan—bullying the tiny people together. What begins with her plucking tinies from between her toes escalates into the siblings fucking on top of skyscrapers, their massive bodies dwarfing the buildings while helpless residents are crushed beneath them and inside her. By evening the whole town is left sticky, and the grinning sister has just one demand: next time, they get even bigger together.
