MUCD-226 - Coming from sticky saliva-swapping kisses! 4 hours of girls having tongue-kissing sex

I bought this because I was drawn in by the title—mentioning sticky saliva exchange, deep kissing, and tongue-heavy intercourse—and Kurugi Aoi on the cover. I was happy with the cast, including Takasugi Mari and Asuka Rin, but since each person only had about 30 minutes, it felt a bit short. I wanted to see more of them.
