If i love her why do I use her part 2

The first few days were kinda awkward, Faith was still reeling from losing not one but both of her parents, I was handling things pretty well. I got faith enrolled in school and after a few days I went back to work and Faith went to school. I tried to make things as “normal” as I could. I didn’t have any of my girlfriends spend the night and I rarely stayed out to late. I felt bad leaving faith home alone but she seemed ok with it. The thoughts of doing things sexually with Faith was still there but now that she was older I knew I did not dare, as I was sure she now knew about sex and I wouldn’t be able to just explain things away as I used to. We got along great as the weeks passed, Faith was a good kid and helped out around the house without being told, we were a lot more like friends than anything.
One night, about 8 weeks or so into us living together Faith came to my room and asked if she could sleep in my bed, that she was thinking of how our family used to be and she was feeling lonely and sad. The moment she said that I felt a twitch in my cock. I said
“No problem kiddo”
As she approached my bed I could see that she had on her typical long night shirt, but as she climbed into bed I got a quick look glance at her ass and saw she had no panties on, Again another twitch in my cock and I began to get hard. Faith lay in bed next to me, I made sure not to let my waist touch her as fear she would feel my hard cock. We laid there talking about things from our past, a little bit of laughing a little bit of sadness, when out of nowhere Faith turned to me and asked “Do you still think I’m pretty? Do I still excite you like I did when I was little?”
I didn’t know what to say, I wasn’t sure what she was even talking about.
“Of course you a pretty girl Faith” I nervously responded waiting for what was going to come out of her mouth next
“I know what you were doing when you thought I was sleeping Dan, why don’t you want to do it anymore, is it because you think you cant, or that I’m to old?”
“What are you talking about Faith?” I said trying to play it off
“You know Dan, when you would masturbate your cock and put your cum on me, its ok Dan, I know why you did it, but how come you don’t want to do it anymore?”
I knew I couldn’t play it off, she was way to sure of what I had done, so I asked her how she knew
“How long did you know Faith? You’re not upset? I m sorry I did those things to you, I was a young horny teenager and I shouldn’t have done those things”
“I didn’t know at the time, it wasn’t until you left that I found out what it was that you were doing, I mean, I knew what was happening, I just didn’t know what it meant why, and don’t feel bad, I have thought about it a lot since you have been gone and I think I like that you used to do that, means you like me, right?”
“So you were awake when I would do those things, I really thought you were sleeping, how did you figure it out? I asked her
“Yes I would pretend to be asleep, I guess I was young and just thought if I woke up you would be mad at me, so I just pretended to be asleep. I’m sure there was times when I was really sleeping, but I think most of the times I was awake. I figured out what it all ment about a year after you left, I was talking with Jamie Higgins, you remember her, from down the street, she was a year older than me, she was at the funeral with her parents, she has become my best friend in school, well we were talking about boys and things and I told her about what you would do and if she ever heard of it, She did and told me a lot of things, and she told me that you could get in a lot of trouble if anyone knew, I made her promise not to tell anyone, I don’t think she ever did cause that was years ago, and we have talked about it a few times so I’m pretty sure it was our secret.
