JF-689 The Breast Enthusiast, Ayana Kyoko
From the title Ooppai Seijin, I expected a big-bust-focused work based on a then-popular meme, but it actually has a real alien setting. A naturally airheaded big-busted girl gets used as a stand-in companion, is attacked from behind while playing billiards in a school uniform, and is assaulted while dressed in an alien-like outfit. It has a risqué feel, but the overly comedic tone in unnecessary places makes it hard to stay focused, giving it a very dated impression. Still, the natural big-bust appeal, including the attractive areola detail and the sense of volume, is excellent.
