PPPE-062 Karen Yuzuriha: While My Girlfriend Was Traveling With Her Friend, I Trained Her Little Sister To Be A Meat Masturbator For 3 Days. Her younger sister, Karen, who is fond of 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.
