Ayumu, Himari, Tsumugi and Nagisa are a group of four childhood friends who have always done everything together. Going to school, studying, playing, traveling, dating... and even sex. It was normal for the four of them to always have sex together but during the summer vacation of their university years, one of the childhood friends, Nagisa, makes a suggestion. ''Don't you all want more time to be alone with Ayumu?'' From that suggestion, Ayumu will spend a ''one-week lover's period'' with each of his three childhood friends... The second week of his lover's period will be spent with Tsumugi, an aspiring voice actress with short black hair! Although Tomoki feels a little embarrassed about being alone with Ayumi again, she wants to make this a fun and productive week, so she makes a suggestion to Ayumi. ''To prepare for the role, let's have sex in various roles during our lover's period.'' Maid, teacher, esthetician... Their lover's period has begun, during which they will be milked of plenty of semen in various cosplays... And on the last day of their lover's period, they will have plenty of sex all day long as new wives...! ?
