Hentai girls enjoy a lesbian experience after workout

A group of combat robot pilots is in practice with their new machines, and they are two couples, one of the women formed by Kayoko and Noriko and one of the men formed by Isamu and Yasuo. The women do an excellent job while the men do a lesser position and finish the training by fighting. Later, after a long day of training, the girls rest in a sauna where they chat, then go for a massage. Noriko feels uncomfortable because she has to undress, so Kayoko gives her a massage to relax her. The massage evolves into something much more pleasurable.
