My wife's daughter recently graduated from college and moved back in with us until she could find a job and save the money to get her own place. I married Lisa when Dana was in grade school and to say that she had grown into a beautiful young woman would have been an understatement.
Dana has always been beautiful but now that she was in her early twenties she had also developed into a very sexy young woman and she didn't seem to mind showing off her sexy body even in front of her mother's husband.
I tried my best not to look at her that way but I am a man and I just couldn't help myself and seeing her parade around the house in next to nothing would inevitably give me a hard on. And since Lisa and I hardly ever had sex anymore I would jack off at night after she went to bed and I started to fantasize about Dana's young sexy body while doing so. I knew it was wrong but I just couldn't help myself.
Then one night not long after Dana moved back in with us I took them both out to dinner as a kind of celebration for Dana graduating from college.
Dana wore a very short skirt really showing off her long sexy legs. She was also wearing a shirt that showed plenty of her ample cleavage and by the way her nipples were poking through it I could tell she wasn't wearing a bra. I had a hard on most of the night from just looking at Dana and I knew I was going to have to jack off after Lisa fell asleep.
Lisa has never been a big drinker and she had a little too much to drink that night and passed out on the way home. When we got there I carried her to bed and after I put her to bed I went back into the kitchen and grabbed myself a beer and went to sit out by the pool.
Dana had mentioned during dinner that she was going to go out when we got home and since I hadn't seen her after I put her mother to bed I just figured she had already left.
After I finished the first beer I went in the house to get another one and when I went back out to the pool I decided to go for a swim. Since Lisa was passed out and Dana had left I decided to just take off my clothes and get in the pool naked.
I had been in the pool for about twenty minutes and I needed another beer. I climbed out, wrapped a towel around my waist and went in and this time I grabbed a few beers and put them on ice and took them out to the pool.
After I got back in the pool I was doing a few laps when all of a sudden I felt like I was not alone. When I looked up I saw Dana standing next to the pool looking down at me and she had a huge grin on her beautiful face.
I did my best to cover myself up but I knew I wasn't going to be able to hide my cock much longer because I could feel it starting to get hard.
I told her I thought she had gone out and asked her to turn around so I could put my clothes back on. Still looking down at me she said "I have a better idea, why don't I take off my clothes and join you in the pool."
I told her that if her mother was to come outside and catch us both naked in the pool she would kill both of us but that didn't seem to faze her. She started to unbutton her shirt and when she pushed it off she revealed the most beautiful breast I had seen in a very long time. They were young and firm and since she was a redhead her hard nipples were a beautiful shade of pink.
By then my dick was so hard I could actually feel it throbbing and I knew if I just pulled on it a few times I would have exploded right there in the pool.
I told her again that it wasn't a very good idea for us to be doing that but she just kept taking off her clothes until she was completely naked. She had brought out a bottle of wine with her and she poured herself another glass and started to climb down in the pool with me.
I now had both hands trying to cover my hard cock and as she moved closer to me she said "you might as well move your hands Craig because I have already seen your hard cock."
I was starting to get really uncomfortable and I told her I was just going to get out of the pool and go to bed but she stopped me by grabbing my hard cock and saying "I have seen the way you look at me Craig and I know you find me sexy because I have seen you get hard on more than one occasion."
I pushed her hand away and said she really shouldn't be doing things like that because I was married to her mother.
She then said "not long after I got back home mom told me that you two hardly ever have sex anymore and she said it wasn't you, she had just lost the desire to be intimate."
Dana took a sip of her wine and continued "and she's scared you might go out and meet someone who is more interested in sex than she is and you will leave her."
I told her that I still loved her mother and I was content with our situation and she asked "and what's that?"
I told her that whenever I get horny I just get myself off and I couldn't believe I was having this conversation with my wife's daughter.
She grabbed my cock again and this time she started moving her hand up and down and said "I would be more than happy to help you out with that Craig if you want me to."
Her small hand moving up and down on my cock felt so good and I know if she kept it up much longer she was going to make me cum.
Before I got to the point of no return I stopped her again and told her it just wasn't right. But she was very persistent and started stroking my cock again and this time she said "I bet you would love me to suck your hard cock and let you cum in my mouth wouldn't you Craig" and all I could do was moan.
She then said "why don't you go lay on one of those chairs and let me take care of you, I promise you won't be disappointed."
I was so turned on by then I couldn't have stopped even if I wanted to and I did exactly as she said.
