The ideal female body that's "very erotic" at first glance—slender yet with enormous breasts. Imagine living naked with two actresses who possess such perfect figures...!? In daily life, doing housework, eating, and having fun, you could always reach out and touch their large breasts and slender waists. It would be impossible not to get an erection!! Furthermore, the rule that once you get an erection, you must immediately have sex is enforced, continuing all day long regardless of your wishes.
