Shota Scratch 10

Vol 2
• May 5th is Adult's Day / 5-gatsu Itsuka wa Otona no Hi (5月5日はおとなの日) by U-hi:
So the premise of this story is two gay shota's, Yochan and Kazumi, "becoming adults" and it starts off with a "if you show me yours, I'll show you mine." As the story proceeds, so does the naughtiness and the secrets that these two shota's share are let out, one by one.
