DNJR-056 - The Secret of That Time: Teasing an M-guy with period blood

Since it involves blood, this is a niche title for enthusiasts. I can watch a beautiful actress's period anytime! I actually found it quite erotic!

It was a pretty sensitive theme, but I enjoyed it! People who are squeamish about blood might want to skip this... The grit shown by Mako Shion for filming while (presumably) not feeling well is amazing!
