Yeah yeah. A flat chested, sadistic, girl who suppresses her feelings for a dopey perverted main character. We've seen that countless times. Although, credit where it's due, there is something this chapter has that's I've hardly ever seen;
someone who's actually interested in Sonic Forces.
now that I think about it, is it normal for her little sister to know about S&M already? I mean she's a middle schooler, right? prolly around 14-15 years old.
