Honnaka's 10th anniversary production! Behind the scenes project!! Aika, Hibiya, and the helper Hoshi-chan, who were not invited to the 10th anniversary production, took a series of trains to Kisarazu, where the front team was shooting, and then rode their bikes from the nearest station to the studio!! What's more, they had a harsh rule that they couldn't continue filming until they'd made one actor cum 10 times! This is the summer struggle of legendary actresses that was secretly taking place behind the scenes of a glamorous group shoot!!
