My step-sister has big breasts. However, she doesn't realize it herself, and she wanders around the house in a super defenseless, braless style... Every time I see her like that, I honestly get a hard-on. In other words, when my step-sister is at home, I'm almost always in an erect state, which is an abnormal situation. And my step-sister, who has been watching my lower body swell up every day, misunderstood that I have a big dick. And then, to me, who is actually of normal size, she approached me with an obvious interest in big dicks, saying, "Big, right?" Is this a chance? Because I also had the ulterior motive of wanting to squeeze my step-sister's big breasts, I decided to cross the line! Anyway, I'm fully erect, so it's a big dick state! We, who were both tormented every day, can't stop! Anyway, we fuck like crazy and cum like crazy! It's a relationship that started from a misunderstanding, but honestly, this isn't bad either.
