Mai-chan, 22 years old. She just moved to Tokyo recently for a job, and it seems she works in the medical field. She looks a bit cool at first glance, but when you talk to her, she's actually quite friendly. She looks at you with pure eyes and laughs at anything you say. Is she just easily amused? Somehow, she's the type that trusts people a little too much. She doesn't know that I'm always hitting on various girls. Does she think all Tokyo guys are kind? Maybe it's because she just came from the countryside? No, she should be a bit more cautious. It's not like she has no experience with men, but she doesn't seem used to playing around at all. She's still not used to handling men, kind of naive. Well, that part is cute too. And then, what catches my eye is this G-cup. A straight smile with beautiful big breasts. Even through her clothes, it's not hidden. Whether she notices my gaze or not, she just smiles normally. Too defenseless. And just like that, Mai-chan follows me to the fuck room. Is this girl okay? Then we naturally have sex. Well, I do this all the time. The G-cup is big. And the shape is beautiful. It's not just big. It's flawless beautiful big breasts. So this was hidden inside those clothes. No, it wasn't hidden. No wonder my eyes drop. Then we kiss. At first, she's a bit passive. But as she gets used to it, she attacks while watching my reaction, attacks. Is she the service type after all? Or is she S? No, maybe she's a self-propelled onahole. She seems more concerned about whether I'm enjoying it than what's done to her. This shows her personality. Well, while doing that, in the end, she also enjoys herself thoroughly—that's Mai-chan quality. This is a win-win?
