Just to let you know, this a work of fiction (unfortunately) and if your offended by incest, please move on.
It started it out with a moment of absent mindedness.
I had a rash in my nether regions that I was treating with prescription medicine my doctor had given me. Because it seemed that the medicine would rub off on my underwear and clothes after I put it on, I began walking around naked in my house for an hour or two after I applied the cream.
This became a routine for me in the morning and then in the evening, as I had to apply the cream twice daily.
I had been doing this for over a month at which time my 38 year old daughter asked me if I'd like her to come and spend a week or two with me. Naturally I responded with an enthusiastic "absolutely" because I truly do love my daughter's company.
So I drove up to her place and picked her up, the drive home was very nice. Just the two of us riding home enjoying each other's company with an occasional banter followed by laughter.
I hadn't told my daughter about my morning and evening routine, to be honest it had slipped my mind.
After we got home to my house, I took my daughter out to a nice dinner at a nice restaurant. I had to laugh at all the gawking the men were doing in the restaurant, admittedly my daughter is very attractive and very busty, which has always caused me the problem of staring at her breasts.
I think that at times she rather enjoyed my inability to not look at her twins, because she'd straighten up and push her chest out when I was staring.
After dinner we went home and had a nice glass of wine and watched a movie. After the movie was over she went to bed and I went into the bathroom to put my cream on. Since she was in bed I didn't find it a problem walking around naked just before I was going to bed.
The next morning I woke and it had completely slipped my mind that my daughter was staying with me for a week or two. I got up and proceeded to go through my daily routine. I cleaned up the areas where I had to apply the cream, then I applied the cream and began walking around my house naked. After the coffee was done, I poured me a cup and walked into my living room (buck naked) and sat on my couch to watch the morning news and drink my coffee.
I guess I woke my daughter up with the noise I had been making because just as I stood up to get me another cup of coffee she walked into the living room. We were both startled, what with me being self-conscious about my nakedness and her seeing me in the buff. However, she didn't avert her eyes or turn away. She just stood there for more than a few seconds staring at my cock.
I have to admit that this kind of made me horny as my dick began to get engorged. After what seemed like eternity, I mumbled an apology to her and rushed to my bedroom to put some clothes on.
Once I was fully clothed I walked back to the living room and apologized to my daughter, and told her I had totally forgot she was there. I then explained my daily routine to her and jokingly, but sounding a little defiant, told her that she could expect me to forget again.
My beautiful baby laughed and said she completely understood and that she often walked around naked just to air out her lady parts, and to not be surprised if she walks around naked.
The thought of my daughter walking around naked in front of me turned me on, my cock began to react to the image of my baby walking around my house in her birthday suit.
I laughed back and told her that I certainly wouldn't have a problem if she wanted to walk around naked, being that's the most natural thing she could do. Once we were done with our playful banter I told her I'd make us breakfast while she took a shower.
Apparently my daughter wasn't just joking about walking around naked, because just as I had finished cooking breakfast and setting the table she walked out of the bathroom. She had wrapped a towel around her and walked up behind me and gave me a huge hug.
I loved the feel of her big tits smashed against my back as she hugged me, and my cock once again reacted by becoming hard, again. After a few seconds of hugging me, my daughter let me go and backed up.
As I turned around to give her a kiss on the cheek her towel accidentally slipped off and fell to the ground. It was my turn to unabashedly stare at her naked and absolutely sexy body.
