National stiefschwester hat mich beim masturbieren zu ihrem bikini erwischt

My stepsister can be a real hurt at times. Take today for example, she barged into my room to wish me Happy Stepsiblings Day without knocking and caught me masturbating. Even worse, I was jerking off to a bikini photo of her. She is pretty fucking hot and has huge tits so I have always wanted to fuck her. I just had know idea she would be into it as well. Turns out, it was a very happy National Stepsiblings Day after all. Who knew stepsis would love anal that much!
