I sneak into my petite stepsister's room to have sex with her and ejaculate in her mouth

I was hanging out with my step-brother when I decided to sneak into my stepsister's room. She's a cute little thing, with big tits and a nice ass. I couldn't resist the temptation to have some fun with her. As soon as she caught me, she started yelling at me for invading her privacy. But I didn't care about that. All I could think about was getting my dick wet. I told her to shut up and just suck my cock. At first, she was hesitant, but then she got into it. She was a pretty good performer, and I could tell that she was enjoying it too. After a few minutes of sucking my dick, I pulled out and shot my load right into her mouth. She wasn't expecting that, but she handled it like a pro. It was a pretty wild experience, and I definitely wouldn't mind doing it again.
