Homemade video of me having sex with my timid stepsister and demonstrating my heterosexuality by ejaculating on her buttocks

My stepsister is always acting shy around me, and I can\'t help but wonder if she\'s into me. So, I decide to put her to the test and show her that I\'m not gay. I take her hard and prove my point, then I end up cumming on her ass. Part 1 of a steamy encounter.
