My parents remarried and I suddenly got a new step-sister! And because our house is small, we have to share a room... But my kind, serious, caring sister is actually a terrible alcoholic! When she comes home drunk, she's extremely foul-mouthed and violent! And when she finds out I'm a virgin, her eyes change color and she attacks me! She came to take away my virginity, which I've been so careful to protect, as well as my first kiss! And she forced me to cum inside her and raped me until she was satisfied!
