any one else had this experience

I am a girl, I can't say my age. (Shouldn't be on this site). I want to confess that I have played with my stepdad's penis while he was asleep. I have done it probably 10 times now. The last time was last night. It was the first time I made him cum. I feel bad but it turns me on so much! It all started about a year ago. I had seen him masturbate a few times, and I couldn't get his cock out of my head. I am not going to get into all the details, but I sneak in at night while he's asleep.My mom works nights and he sleeps naked so its easy. Now that I know I can make him cum, I want to do it more. I just don't know what went through his mind when I woke up this morning. He had his cum on him. Anyone else have this experience? Any suggestions?
