Two younger sisters with different fathers and different mothers

Suddenly I have two younger half-sisters thanks to my father. They are both very beautiful and famous online streamers. However, I still don't care much because she is now my half-sister. But on the contrary, the two of them always found ways to harass me, in every way to stimulate me. Even though I didn't care much, things got worse and worse.
