The popular series is back, in search of beauties in summer clothes! Perhaps the mischievous Kokoro is aroused by the man who flinches in the women-only car, so they take advantage of the crowded train and get close enough to kiss him, pressing their breasts and buttocks together. The man's erection and troubled expression make the beautiful sluts even more excited, and they hide in the shadows to show off their bare breasts and give him a blowjob. What's more, they even end up having sex with all of the beautiful sluts in this episode. Does summer make women bolder?!
