I'm doing yoga when my step brother walks in and plops down on the bed to watch. I can see his cock getting hard through his pants and my mouth starts to get wet just thinking about it! I crawl over to him and pull his cock out! I put him in my mouth and I pull out my tits. I use my hand to jerk him up and down and into my mouth. I go fast and slow, teasing him with my tongue and my spit! I can feel him getting close so I jerk him hard until he cums in my mouth and all over my hands. It runs down my arm and I lick it up; I love cum so much :)
