Title is as suggested. Koharu teases her older brother a lot believing she can get away with it. It starts off small, panty or bra flash here or there. Eventually, she tries even riskier teases like whipping out a tit or showing off her pussy. One day she pushes her brother too far and he actually "forces" himself onto her. (She's into it but tries to pretend she's not at first) Instead of calling him Oniichan she will call him Aniki, it's basically a less formal way to say older brother. It can be kind of impolite/rude but that just shows how much their relationship has changed. If their relationship gets fixed, maybe she will go back to calling him Oniichan again! Or maybe... when he's pleasing her it turns her into a good girl again. We've got options~
