Kohana Suzumiya, 19 years old, has the vibe of a traditional, pure, honor student young lady! She's the kind of beautiful girl you'd expect to find in a certain national idol group! She looks very serious, but when you talk to her, she seems a bit mysterious? Her favorite food is octopus wasabi, and her hobby is walking. Quite a sophisticated choice for someone so young. And what's more, what's noteworthy are her breasts, which you wouldn't expect from her serious appearance! Her beautiful, round breasts, which started growing rapidly and are still growing, are apparently an F cup! When it comes to gentle, ladylike characters, big breasts are a must-have moe point! She seems innocent, but was it really okay for her to follow such a suspicious old man around? When I asked her when she had her first experience, she gave me the surprising answer, "three months ago"! I see, so up until three months ago, she was a traditional, pure, honor student young lady! And so, she's taken the steps to adulthood and started on the path to becoming a lewd, big-breasted woman! !! I understand!!! Please take a look at Kohana-chan's innocent sex!!!
