My 20 year old step daughter has come on to me many times in the last year. She is very attractive obviously resembles her mother in her 20’s. Only thing that stops me from pursuing is that I have been in her life for the last 7 years and that it would feel more comfortable if her mother were to be a part of it. I don’t feel like a dirty old man, but I don’t want to be one either. But I can’t honestly say I’d be able to stop myself if she were to make a serious advance move either. I’m pretty sure I could go back to my normal routine but would be afraid she couldn’t, or maybe I am just over thinking it, but I would enjoy her in bed with my wife in a comfortable environment
