Nagi-kun makes his comeback as an erotic man after a 2-year hiatus, and appears with a more mature charm♪ His partner Kokoro-chan is more of a masochist, and is apparently a bit too sensitive... but Nagi-kun is the same way! They take turns attacking each other as if they are serving each other, and because they both want to be treated the same way, they end up enhancing each other again and again, resulting in a luxurious and exciting experience♪
