I hadn't seen my step-sister for two years. She invited me to spend the summer with her. Now that she if finished with college and has a job and her own apartment it would be a fun summer. She started coming on to me. I thought she was high on something but she said she was not and was OK. We started to examine our bodies and she started to eat my cunt. Then she had me eat hers. I asked her what her boyfriend would think of us having girl on girl sex, that is when she admitted she did not have a boyfriend and was a lesbian.
