I have a 28yr old stepdaughter that has a smoking hot body but has had trouble with meeting the right guy. She has been single for about a year and a half only had a couple dates that went nowhere. Last night my wife was telling me how frustrated the daughter is and how she misses the feeling of a man and that her vibrator just isn’t doing it anymore. She then tells me she wants me to do them both a favor and have sex with her. My wife and I have a pretty open mind about sex and have done things most couples would be uncomfortable with but this is something I have never imagined. I am torn on whether or not I should go ahead and do it. Like I said she is smoking hot and it would definitely be a good time. On the other hand I think of her as my daughter and I would hate to have things change in how close we are now. What do you all think
