Three and a half years ago, my wife Judy was diagnosed with an advanced case of Addison's Disease. Without going into detail, it causes the endocrine system to basically shut down and the body doesn't develop the hormones the body needs to function properly. She has to take a bevy of drugs to counteract this and replace what is missing. As a result, there are some side effects. In Judy's case, one of the side effects is that she lost the desire for sex completely. She is still a very loving and compassionate woman, she just doesn't want to have sex. I can't even talk her into a handjob. The doctors tried a supplement to increase her desire, but the side effects were less than favorable.
At the time, an affair wasn't even something I thought about. So, I resorted to the only thing I could do, masturbation. I started using different websites for stimulation and that was how I discovered Literotica. I started looking at the different things on Lit and found I really liked the Taboo/Incest sites. As I would read the different stories of brothers and sisters, cousins, moms and sons/daughters, the ones that really got to me were the father/daughter stories. They always made me cum the hardest. I guess because I am the father of 3 adult daughters named Tina 42, Patty 40 and April 38.
As I would read a story about a father and his daughter, I found that I was seeing myself as the Dad and putting Patty in the place of the daughter as she and I were the closest of the three. I would imagine it was Patty in the story trying to seduce me, or me seducing her or her rubbing her tits on my chest during a hug or putting her hand on my dick while sitting at a table. We became the centerpiece of the stories. It finally got to the point that I would get an erection whenever we were actually together. All I needed to do was just see her and the stories would start going through my mind. I would work very hard to control myself and be very careful when hugging her or giving her a hello/good by kiss to not let her feel it if I became hard. This was hard work because of our closeness. Plus, she was always playfully tease me whenever we were together.
As time went by, it was almost like Patty was picking up the vibe. The hugs got a little tighter, really pressing her boobs into my chest or hold the kiss just a little longer. When we got together at their pool, she would bend over to give me a view of her 34C tits or of her tight ass. I spent a lot of time submerged in the water! I was doing my best to keep things on the level. But, the tension was almost palpable. I really didn't need any other stimulus when jacking off, just close my eyes and think of her. I kept my distance during our hugs because I didn't want her to think I was a weirdo or possibly have her freak out. It was really affecting me and so I decided to do something about it. The next time we hugged, if I got hard I was going to let her feel it. All I could hope for was that she wouldn't notice and if she did, not make a scene and give me a chance to apologize privately.
The opportunity came a few weeks after I made my decision. It was time for our annual family reunion and it was being held about 3 hours north of where we all live. Judy wasn't going as she wasn't feeling well and Patty's husband had to work as did Tina and April. Patty's boys decided they wanted to spend the weekend with their other grandparents, so it was just Patty and I. I was going to drive so Patty said she would meet me at our house and she could see her Mom. When she got there, she hugged her Mom and then gave me a hug. I had sprouted a partial erection and I know she felt it because she stiffened slightly and gave me a funny look. I stepped back and told them I would get her bags from her car and put them in mine so we could go.
Judy and Patty went into the house to talk, also so Patty could use the bathroom before we left. I went in, gave Judy a kiss and told her to call if she needed anything. Patty and I loaded into the car and headed out. For the first hour of the drive, there was a nervous quiet between us. Finally, Patty broke the silence by asking straight out if my erection was because of her. I said yes and started to apologize. I embarrassingly told her what had been going on because of her mother's medical condition and what I had been doing to resolve my issues with no sex. I was as red as a beet and told her I hoped she didn't think I was a pervert. Being a nurse, she fully understood. What she said next blew my mind! She was flattered to be the object of my masturbation fantasies and she had a secret of her own to tell me.
