I got a call from my step-daughter late in the night. She was at a girl friend's place and she asked me if I could pick her up, because she was a bit altered with the drinking. When got there, it became obvious they've being having lesbian sex and that was a complete surprise for me. I never thought my step-daughter liked girls. She then told me she was bisexual, but she was really fed up with men. She couldn't reach orgasm with most of them, only with girls. So I took her home and decided to show her how she really needed to be treated and make her cum several times. She didn't know she liked it rough.
