Nevlastní sestra ignoruje honění a šukání při čtení knihy - EVA MYST

I walked into my stepsister's room while she was reading a book, lying on the bed. I started flirting with her, but she ignored me, keeping her eyes on the book. Then I decided to jerk off to her, and she even helped me by touching my cock. In the end she let me fuck her, even though she continued reading the book, I wonder why she ignored me?
