Synopsis

My father remarried. He brought a stepdaughter to the house. She's a younger stepsibling from his partner's previous marriage who came into my life. The "stepsister" who suddenly appeared. My classmates tease her, and even my new girlfriend is jealous of her. Everyday I'm left confused by the changes in my living environment. One day, I went to the bathroom to take a shower right after I got home... There she was. My younger stepsister. And she was naked; I can't get her breasts out of my mind. I've warned her to lock the door to the bathroom, but all she says is, "Okay." What is up with this girl? After school, my girlfriend called me out. She says I've been acting weird lately; I don't think that's true. She's mad at me because she thinks I have feelings for my stepsister. I'm sure my girlfriend isn't the type of girl who gets hysterical like this. But lucky me! She's in the mood. Finally, my longed-for "fuck around" life is right in front of me... Wait, what? Why is my stepsister here? I was so close to getting laid; I was about to get laid! 'Take responsibility!' I said. I know that saying such a thing is meaningless. But... "Okay." What? All she really says is "Okay." If it comes to this... 'Then let me fondle your breasts.' I told her. ...I'm insane, I'm crazy, I'm sorry, forget it. I said that I've calmed down and I'm reflecting on my own remarks. "Okay." I was looking at my stepsister with her breasts exposed in front of me. There's no way I can stop now, right? Oh, so smooth, so soft... No matter what I say, all she says is "Okay." My stepsister is mine and mine alone. [Submissive] The first part of a new series by the popular author Bifidus has begun!
