MU-302 - 接吻遊戯 レズキス 01

They just kiss endlessly throughout the whole thing. Plus, 90% of the camera work is just close-ups of their mouths. They barely even make any moaning sounds. A long time ago, there were tons of these 'kissing videos' released, and I remember getting bored of them quickly because they were so monotonous. I never expected one to be re-released in 2017. It gets boring halfway through.
