I'm a 67 year old, pudgy, bald male. My wife who was a few years older than me died in 2010. In 2003 we took in my wifes neice Tammy who was 24 at the time. She was severely injured in a bike accident when she was a young teenager and still today can only get around on crutches. She also has stomach problems, often getting sick to her stomach and has to take laxitives often. Her mother is phsically disabled for over 15 years and my wife and I were stuck with Tammy. My wife babyed her and took care of her all those years and before I retired never knew how much of a problem Tammy was and always considered her a pain in the ass. After my wife died I didn't know what to do about her but she really has no where to go. I couldn't very well kick her out so I did hire a woman to care for her. After only a few months I realized I couldn't afford to keep paying for this woman and began having her come only twice a week. Thats when I began tending to Tammy most of the time. I did feel sorry for her and she only has one real friend who visits her once in awhile. I take her to see her mother every Saturday, who is now in a nursing home. In all the years Tammy lived with my wife and I there was never a time I saw Tammy naked, that is until about 6 months after my wife passed away. She messed herself in bed and was crying pathetically. When I say mess it was worse than that and almost got me sick. She was almost hysterical about it and when I came in I wasn't sure how to handle such a situation. Although I knew she was embarrassed she let me take her pajamas off. I first wiped her body off and then picked her up naked and carried her to the shower sitting her down on the chair she uses all the time. While she cleaned herself I cleaned up her bed putting on new sheets and pillow cases. When I went back to the bathroom she allowed me to dry her off and for the first time I saw how beautiful her body is. Her breasts aren't very big but they are firm and aside from her right leg her body is almost perfect. I still had a women coming twice a week at the time. The next day when Tammy told me how embarrassed she was at me seeing her nude I told her it didn't matter and that I was an old man. I also told her she better get used to it because I couldn't afford to keep paying people to take care of her. Since then I have become an old horny man who jerks off everyday. I began helping her into and out of the shower on a regular basis and the first 3 or four months she was extremely embarrassed by me seeing her nude all the time. I try not to let her think I have interest in seeing her and because of my age I think now she does think it has no effect on me. I don't have to dress her after her shower but she does allow me to dry her off and over the last year or so allows me to massage her which my wife used to do for her. At first I only massaged her back and legs. Then I began doing it right after her shower and would put her down nude on the bed and massage her that way. I do get a hard on all the time but have never exposed myself to her. I think she is still a little embarrassed but I still massage her while she is naked every other day. I began touching her in places I shouldn't but she never complained or told me not to. I act like its not a big deal but get erections all the time. I can't believe how she lets me rub her breast and never says a word when I rub her vagina. I don't penitrate her with my fingers but I can tell sometimes when she gets aroused herself especially when I am putting shin lotion all over her body. She allows me to use the lotion inside her crack and when she is constipated has often let me put a supositorie into her. About 11 months ago was the first time I saw her masturbating. It was right after I gave her a massage and I knew that day I had gotten her aroused. I don't do it often but have watched her masturbate when she doesn't know I am still at her bedroom door. I do take good care of her but I also take advantage of her whenever I want and she never complains or objects to it in any way. She always tells me she is embarrassed by me taking her to the shower and massaging her but it is not noticeable like it was when I first began doing all this to her. She must think I am to old to have any concerns or sexual feelings about it anymore. If she knew how often I masturbate she would think differently about it. I don't think she realizes how I intentionally try to arouse her always wanting to watch her masturbate. I can usually tell when she is aroused just by the way she moves her eyes and how her pelvis starts to squirm when I rub her vagina or touch her anus. Sometimes it takes an hour for me to rub her down and by that time I feel like my scrotum will explode if I don't jerk off soon. She constanly thanks me for all the tings I do for her which includes cooking, cleaning and washing her clothes. She thanks me for helping her with her bathroom needs and thanks me everytime I massage her. I think she is oblivious to the fact that I am always sexually aroused when she is naked and often masturbate as many as 10 or 12 times each week. She doesn't realize I have become a pervert since I started taking care of her. as much as I would like to I have no intentions of having sex with her. I have considered trying to masturbate her at times but only rub her vagina and have never tried to finger her there. She lets me put skin lotion on her breasts and allows me to spread her legs open to apply it. I move her around any way I want and do this only to give myself a better view of her. There isn't a spot on her body I havn't touched and have seen her in the most undignified ways imaginable. She still has bowel problems and that part of it I don't care for when she does make a mess in her bed. Thanfully it doesn't happen to often and when it does, that is when I can see the embarrssment in her face and know how humiliating it is for her. Other than that she is agreeable to anything I do. All the years I was married I never cheated on my wife and never came close to what I am doing to Tammy. As long as she allows me to I will keep doing it, not just for her but for my sexual excitement.
