Due to my parents' remarriage, I suddenly got a stepsister! And since our house is small, we have to share a room… But the kind, serious, and caring sister turns out to be an alcoholic! When she comes home drunk, she's extremely foul-mouthed and violent! And when she found out that I'm a virgin, her eyes changed, and she attacked me! Of course, my first kiss was taken, and she even stole my cherished virginity! On top of that, I was forced to ejaculate inside her and was raped repeatedly until she was satisfied!
