I got my SB into it a little so far.
I will ask her if I can be naughty and she will tell me yes or no.
If it is yes I will rub it for a few, then she will let me know when I can be a little more naughty. Pinky, forefinger, thumb. I only fucked her once and it took about a half hour or so to play. Once she relaxed and I could feel it I gently went in. I didnt go too deep with her, just enough to get the feel. About a minute of that she said thats enough.
