Kazushi Sudou is a university student who is visited by his two childhood friends, the sisters Ayane and Kotone Shirakawa. When Ayane discovers that Kazushi not only forgot to buy her pudding but is also using her special lotion in the bath, she decides to take revenge and join Kazushi in his bath along with Kotone. Will the perverted Kazushi be able to remain indifferent to them both?
Ayane Shirakawa
She is very conscious about beauty and always tries to improve herself. Such as when she saves her pocket money to buy beauty products and bath salts. Although she tends to reflectively adopt a cold attitude towards Kazushi, deep down she worries about not being able to be honest with him. Her favorite food is Pudding.
Kotone Shirakawa
(Younger sister of the Shirakawa sisters) She may look gentle, but she's actually very bold. (Little Devil Type) Along with Ayane, she looks up to her childhood friend Kazushi like an older brother. Recently, my breasts have grown larger and my clothes don't fit anymore. I'm worried about what's happening. My favorite food is Cream Stew.
A University student who lives in an apartment near the Shirakwa Family's house. Although he is not related by blood to the Shirakawa sisters, they grew up like siblings from a young age and he loves them like his own family. In fact, he is a struggling student and spends his days working part time jobs. Just between you and me, I'm worried because my sisters are hanging out in their apartment all day and night, forcing me to live a life of abstinence.
