FSDSS-828 A summer when my older childhood friend, who had become a dried-up NEET mourner, was awakened by her first real dick and indulged in extreme sex. - Mami Mashiro

``Would you like to go kill some monsters with me after a long time?'' My childhood friend Mami-chan, who I met again when I returned home for the first time in several years, has become a dried-up NEET who shuts herself in a dirty room. - Her hair is unkempt, her clothes are sloppy, and her big breasts have grown in vain. - Irregular diet, life without meeting anyone. - She is a mourning woman who has given up on being a woman, but... there is an electric massager lying in the corner of the scattered room.
