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.
Rather than hurriedly reach down and put her towel on, she casually bent down and picked up her towel. Of course I was staring at her nakedness the whole time, trying to imprint in my mind her gorgeous naked body with the intent of masturbating while re-living that moment in my mind.
To my shock, my daughter didn't wrap the towel around her to cover herself again. She draped it on the back of the chair and then sat down and began eating her breakfast. I wasn't sure what to do, but because I loved seeing her naked in front of me, I also sat down and began eating my food determined to not make a big deal of it.
It seemed like my daughter was on a mission, because once we were finished eating breakfast she casually walked into the living room while still naked and put on a movie. I put all the dishes in the sink and then followed her into the living room.
I sat down next to my daughter and began watching the movie with her, of course I was doing more staring at her tits and that beautiful black bush of hers than watching the movie. She was completely aware of my gawking and gave me absolutely no hint that it bothered her. In fact she would occasionally spread her legs just so slightly allowing me to see her pussy lips and her clit. Clearly this little game turned her on because her clit was engorged just like my cock had become.
After a few minutes of her displaying her womanhood we began a frank conversation. She started by telling me how happy she was that I was able to accept her nudity. Because I obviously loved seeing my daughter naked, I responded by telling her that nudity is the most naturally state of being, and besides, she has the sexiest and most gorgeous body I'd ever seen.
She smiled with delight hearing me accept her nudity and with me telling her she was sexy and had a gorgeous body. Then she fulfilled my hope and desires at that moment, and told me I should get naked and just enjoy the morning. I didn't need any encouragement, I immediately stood up and slipped off my pajama bottoms and then my shirt becoming just as naked as she was.
Of course my dick was completely hard by this time, causing my daughter's eyes to become glued to my rock hard cock. I could see the lust in her eyes, as I'm sure she could see the lust in mine.
I sat down on the couch next to my daughter and she slid up right next to me, pressing her naked body against mine. I put my arm around her but made no attempt to touch her huge knockers, although I so wanted to.
After a few minutes of us pretending to be normal, she asked me what I thought about masturbation. Since I regularly jacked off, I told her I didn't think there was any problem with masturbating and admitted that I masturbated daily, sometimes as many as 3 times a day. She laughed and told me that I was quite a horny man, she's right I am constantly horny.
I then asked her if she enjoyed masturbating, to which she replied of course she did and she also masturbated daily. I knew she masturbated because I would hear her masturbating in her room on those occasions she had come to spend a week with me. She also said that there were times she would masturbate several times a day just like me.
I sat there, with a hard on, thinking about what we were doing and contemplating on whether or not I should make a move, because clearly she wanted more to happen. But before I could do anything, my daughter asked me what I thought about mutual masturbation.
