Introverted stepsister gets a rough pounding from me, proving my heterosexuality as I climax in her anus

The video kicks off with this introverted stepsister of mine who's been giving me a hard time lately. I've been trying to prove to her that I'm not gay, but let's be real, who am I kidding? I've got a huge crush on her. So, I decide to show her what I've really got. I take her to the basement, strip her down, and start pounding that tight ass. I can see the surprise on her face as I thrust deeper and deeper, hitting that sweet spot. Before I know it, she's squirting all over the place, and I'm lost in the moment. I keep going, pounding that ass until I can feel myself cumming. I pull out and cover her perfect ass with my hot load. As I watch her lick up every drop, I realize that this is the best proof of my heterosexuality.
