GCD-749 - 30 excretions by 7 perfect mature women, the ultimate display

It's an older title, but the quality of the actresses is high, and more importantly, you can tell they're actually enjoying the play, so it never gets boring. It's not overly extreme, but the 'real defecation' is the main selling point. The first actress does more extreme stuff in other labels, but unfortunately, that's fake. Aoi-san's real defecation—especially the vulgar, lewd sounds during the enema scene—is a personal treasure. There are no misses with the other actresses either; it's a great value compilation.
