Motto! Debutopia [Japanese]

Description:

Young boy Yorimasa has a thing for curvy girls, and meets three sisters.

Three deliciously corpulent, squeezable, loveable chubby girls… and all in the same family! All in the same household! His new life under this overfull house of plenty is a paradise.

Yorimasa’s longtime wishes converge on a hot christmas morning. Which sister will he celebrate with? Can he somehow get all three at once!?
He’s wrapped in a world of womanly softness! Give him a goal! Or will he be smothered!?
