Ignored Stepbrother Cums on Yoga Pants

I had a pretty stressful day at work so I was trying to unwind with some yoga. Of course my fucking stepbrother has to walk in right when I’m getting started! He’s nice enough but he’s such a creep sometimes. I caught him recording me and he said I should let him get a video to jerk off to because it isn’t fair to keep working out in front of him. I wasn’t in the mood to deal with him so I chased him out of the room. He came back like two minutes later, this time he was naked with his dick in his hand, it was pretty pathetic. I actually felt kinda bad for him so I agreed to let him watch me as long as he didn’t take too long to finish. I think he took advantage of the situation because he took a lot longer to cum than I would have liked, I had to keep telling him to hurry it up. On top of that, he decided it would be funny to cum all over my yoga pants and totally ruined them. I was so pissed at him afterwards, I just laid there for a second like “are you fucking kidding me?&quo
