Oppai Life

There lived a boy, Naoto and two girls - Chica and Ayan. When we were kids they were inseparable friends and played together. The time has passed. The girls grew up, became adults - beautiful and graceful, and they have something up (see the title). With this size, which is the average onemany a male character that Drools to the floor, and the average Japanese (not onemana) begins to assume a downright jealousy. No need to say that the boy also grew up in a hefty fellow, and he, too, grew up... Well, you know what... Japanese men are too jealous.
Everything was good, but there is one problem: both girls immensely fond of the boy. So he faces an impossible dilemma: who do they choose? Choose one offended the other. But maybe there are some options that will suit everyone?
