Her younger sister, Karen, who is attached to me. I thought she was annoying at first... I changed my mind after she started to suspect that the person she was traveling with was a man. She's worried about her...I distracted her with your sister... If you're going to cheat on me, I'll cheat first... That's how I felt, but... Her act towards Karen, who accepts anything, escalated. Infidelity, betrayal, SEX alone is not enough, blindfold, handcuffs, training, and so on.
