I was trying to vent to Dani about my night out with a guy and she wasn't listening to me! She was watching porn! Right next to me! I looked at her phone to see it was lesbian porn. I confronted her and she admitted to being curious. She thinks she might be into women more than she thought she was. I offer to help out. We are STEP-sisters so we're more like friends than anything else. We slowly touch one another and get more and more worked up. I oiled up and groped her huge tits before we rubbed our nipples against each other. She brings out a HUGE dildo and we take turns making each other cum with it!
