My girlfriends stepmommy fucks my brains out

I finally met a girl I really like and she wanted me to meet and get to know her stepmom. The day we were going to her stepmom my girlfriend got called into work. I said it was no big deal and I could meet her on my own. I knocked and the lady that greeted me was the spitting image of my girlfriend. I introduced myself and apparently, she knew that I was coming because she let me into her house easily enough. We sat in the living room and she started out by asking me some questions which I answered honestly and then the conversation turned odd. Point blank she came out and asked me if I had slept with her stepdaughter yet. She asked if she could take a nap with me.
