KTKB-002 - Flat-chested genius bishoujo, turns out she's a cum-addicted slut who loves older men

An adult face for an 18-year-old? And despite having almost no chest, her sensitivity is off the charts. She has a body like that, but she's sexually mature. I don't know if it's a good thing or a bad thing... but she's debuted in AV as a 'flat-chested genius.' Plus, she says she likes older men and cum, which makes her a very convenient AV performer. She gives head, has sex, takes the load, and climaxes in pleasure. Even for us older guys, she makes our dicks hard despite that loli physique, so she must be naturally lewd. This 'flat-chested genius' is as tough as a marathon runner. Let's look forward to seeing if she keeps making AVs and what kind of performances she'll show us next.
