I understand your situation.

I have been so tempted with my Young Friend on so many occasions.
And it feels like, he almost WANTS me to do something.
And I just noticed how bad THAT sounded.

The worst I have ever done, that I do now regret, is that he was mucking around and asked for a foot massage, and I just accepted 'because I was bored'.
I eventually made it up to his thighs, he didn't care one bit.
I'm afraid every day that he didn't really want it, but just let me because I did.

As long as you don't hurt the boy, everything will be alright.
