ROOM-044 - High school girls broken by perverted old men

I bought all of Miku Maina's 4K works after seeing her play the partner to Nene Hatsune in that 'Zukkoke' incest series. The title says 240 minutes, but the actual runtime is just under 4 hours and 6 minutes. I thought 266 divided by 3 would be 88 minutes each, but it's 91:104:71. The first girl is just a generic big-bodied pussy-shaved girl, the second is the pretty Marina-sama. If that's the case, Miku-chan should have been the main event, so I'm annoyed her segment is so short. Miku-chan isn't exactly pretty compared to the first two and isn't shaved, but her 'average-looking' charm actually turns me on. If they knew what they were doing, they would've given her more screen time. Was the first girl even necessary? A proper edit would have been 70:90:85.
