First time I saw my stepdaughter naked.

The first time I saw my stepdaughter naked she was 19 years old. My wife was out of town on business and I was supposed to have left the day before to go out of town on business however my client called me and we rescheduled the afternoon before this happened. At the time my stepdaughter was working at a coffee shop and had to open the doors at 6 AM sometimes so she was typically up at 4:30 AM to get ready on those days.
Well this particular morning she obviously thought I was out of town because I woke up about 430 in the morning to the sound of her shower running. The upstairs bathroom she used is directly across from our master bedroom and when the bathroom light is on and our bedroom light is off she can't see into our bedroom.
When I was waking up to the sound of the shower I was a little irritated as you can imagine. However that changed when I saw my 19-year-old stepdaughter naked bending over and adjusting the temperature of the water. Her perfect legs and smooth perfect ass were a sight to behold! I couldn't believe my eyes. I immediately surmised what happened and stayed perfectly still because she thought I was not at home. It was wonderful to see her standing in front of the bathroom mirror completely naked waiting for the water in the shower to get the perfect temperature. I have been fantasizing about my stepdaughter since the year she got her drivers license which is when she really started to turn into a beautiful young woman. And after years and years of dance class five nights a week she had the perfect body.
A beautiful lithe body with excellent muscle tone, very small breasts are perfect ass and lovely long legs… And a completely shaved pussy!
I am mediately started to get hard on looking at her beautiful body. Then when she got into the shower and close the shower curtain I took action. I got the Vaseline out and started stroking my cock and I waited. I knew that when she was done showering she would turn the water off and slide the shower curtain back and I would have a perfect view of her perfect body all glistening and wet and I wanted to be ready to blow my load at that point. And that's exactly what happened, I stroked I stroked until I was on the verge of coming and once she slid that shower curtain back I blew my load so hard when I saw her perfect body I almost screamed out. I watched her towel off and then go into her room to get dressed. She came back out of her bedroom dressed to do her hair and put her makeup on and I stay perfectly still until she left to go to work.
