Masturbating in my stepsister's panties while she's away: A family affair

Oh boy, do I have a story for you! So, I was minding my own business when I heard this loud moaning coming from my stepsister's room. I figured she was just having a little fun, so I kept on with my own business. But then, I heard her scream! And it wasn't just any scream, it was a Portuguese scream! I knew something was up and I couldn't resist going in to investigate. And boy, was I glad I did! I walked in and saw my stepsister, all dressed up in her panties, getting herself off. I couldn't believe it! But then, it hit me - this was a family affair! I mean, she was trusting me enough to let me in and watch her get off. And let me tell you, she got off good! Her moans were so loud and her panties were so tight, I couldn't help but join in on the fun. And the best part? I didn't even have to leave my house! It was like my own personal orgy, all thanks to my stepsister. So, if you're looking for a good time and don't want to leave your house, check out this video. It'll be the best family affair you've ever had!.
