There are screencaps of her latest release here:

While I'm not to fond of her hairstyle, this title is still smoking hot based on the caps.
She really isn't shy in showing off how smooth she is down there. Does it more than once in this title alone.
See something you like? Quite a lot of it in this title too.
And cos its the older Koharu, you know she's going to be showing off her best asset often.
