Ok so here's a bit of the background story. I'm currently in a relationship with my girlfriend of almost 6 years, she has no idea about my love of diapers. I have no real urge to tell her either because I would never wear around her anyways, its more of a private thing for me. I know she would be accepting of it and probably encourage me to wear around her but I'm not at that point of feeling comfortable with it enough. I work the night shift and she works days so I get to wear during the week while I'm home.
As usual I ended the week spending Friday diapered. I was just laying on the couch watching some movies when I passed out. I heard the door open but I wasn't in a panic I was wearing track pants over my "girls" goodnights and I knew it was only my 12 year old step daughter. She came into the living room talking to me then she stammered a little bit when she looked into my direction but I thought nothing of it. She just stood at the end of the couch where my feet were looking at me oddly and was just rambling on in a way that people do when your trying delay or distract them. Finally after a few minutes she went upstairs, that's when I realised because of the way I was lying down the waist of my pants were down a bit in the back and my shirt had ridden up a little leaving about one to two inches of the pullup exposed.
Of all people to find out. If she did I hope she can keep quiet about it, I know she'll probably tell her mom and I can live with that but I definitely did not want her or anybody else to know.
Does anyone have any advice on the situation?
