Looking on my 6 and a half months pregnant stepdaughter

My stepdaughter is 19 & 6 1/2 months pregnant. She has been my stepdaughter for 2 years and I will admit that I've had my fantasies about her, but never acted on them, other than watching her, and occasionally I tried to sneak a peak while she was dressing and she was a little perturbed when she saw me in the mirror. We started to talk about my feelings toward her and we made a little agreement. She was going to let me see her completely naked and I wouldn't have to sneak around to do it. For this, I promised to try and stop freaking her out by looking on her. We went into the guest room and I put on some sexy music. Elaine started to strip off her clothes and she was fantastic with her big belly fully showing. Elaine was not smoking during her pregnancy, but during her nude dance, Elaine posed with a lit cigarette for me to satisfy my smoking fetish. After her nude dance, I got her on the guest room bed where I watched her smoke and pose again. Wow, it looked so sexy!
