Step-sister and I, both amateurs, dressed as unicorns for a kinky cosplay session. She mounted me, riding my throbbing cock, while I pleasured her. The intense encounter ended with a creampie-filled climax.
Step-sister and I always had some kind of strange relationship. She was always trying to get me to fuck her, but I was never really into it. But one day, when she was coming back from shopping, she brought some costumes for us to play dress up. We decided to cosplay as unicorns and I had to bend her over to get the unicorn horn on her ass. And then we started having sex. At first, it was just because of the costumes, but soon it turned into something much more. She was riding me like a cowgirl, and I could feel her moaning in pleasure. It was like she had been waiting for this for a long time. When I was about to cum, I pulled out and let her feel my hot cum all over her body.
