Tomofu rice treasure!~Introducing Ogyari activities are becoming more and more cured~

The main character, Osai Haruki, is a corporate slave. He worked his way through daily life as a systems engineer, and his spirit reached its limits. At that time, my family psychiatrist Minato Sakura suggests me to do "hypertherapy."It is said to release desires that lie deep within the heart and relieve mental oppression. Koyamauchi was skeptical that there was no way he could do anything like that, but once he received the hyung...  "Bubuuuuuu!"  There was Koyamauchi, who had regressed. It seems that Koyamauchi had a desire to regress.Sakura might be shocked by this adult man who is as difficult as a baby and seeks breast milk...   "Ah... after all! That's what it was after all." "I've been impressed since I first came to the clinic! I was scared!" "'Oh, this guy won't bum me!'! Yes yes! I wasn't crazy about my sister's eyes!"  ... In fact, she also has an excessive maternal nature with nowhere to go, and she easily accepts this.After that, Koyamauchi recovers from his baby state, but suddenly regresses, causing him to become unable to lead a decent daily life. So Sakura takes a break from work and proposes that she solve the event by living together. However, Sakura's younger sister, Minato Yuki, is highly opposed.Although he is a good adult, he hates Koyamauchi, who is pampered by his sister. However, after living at her sister's house for a while, she discovers that Yuki also has an incredibly maternal self-confidence, just like her sister, who wants to pamper someone else -- andamp;nbsp; Her mind, tired of modern society, is sweetly healed by sex...!The ultimate babumi and odd motion anime!
