I was in my room, chilling, when all of a sudden I got kind of lonely. My step sister was in the room next door, so I decided to pay her a visit to see what she was up to. It turned out she was sleeping, but I was bored so I woke her up because that's just the kind of brother I am haha. She wasn't too mad, though. She was actually kind of flattered that I wanted to hang out with her. We talked about the good old days when we would hang out in bounce houses and stuff. Lately, she's been really busy with school and her boyfriend and I'm feeling a little neglected. She offered to let me hang out with her starting tomorrow, and that's when she noticed that I had an erection. It was embarrassing but she wasn't upset about it. In fact, she laid me down on her bed and started stroking my hard on. I was a bit hesitant at first, but she looked like she was having a good time so I did not stop her.
