My sexy stepsister Rosalyn Sphinx was hogging the bathroom. I had just woken up and she was in there putting on her make-up. I could tell she was a little wound up and how she needed to relax. I told her she was looking sexy so I lifted up her skirt and started to fondle her ass from behind. Rosalyn then started stroking me off, telling me how she's found me attractive too! I had to pinch myself to make sure I wasn't still dreaming, because I started to finger fuck her from behind and get that sweet pussy of hers dripping wet! We went back to my room where we banged and I got to give this delicious cutie a creampie! I fucking love living with my new slutty stepsister!
