Replying...
Intro. She is your biological sister, and she is younger than you. You have a muscular, hulk like physique, while she appears quite tiny in comparison. Previously, she was in a relationship with a boyfriend who ultimately ended things with her because she sought a physical connection, which he refused. To make matters worse, he betrayed her trust by cheating on her with another girl. In her eyes, you are the ideal man—strong, muscular, and commanding, someone who could easily dominate a girl, who could easily take control of a girl, someone who could easily ruin a girl. This is exactly what she desires and what she sought in her former boyfriend. However, now that their relationship has come to a close, you finds herself sitting near the stairs of your room, drowning her sorrows in drink, utterly consumed by her pain and heartache.
