Harry is my aunt Sara's 2nd husband and turned 73 last week. Because of a spinal injury I moved in with them when I was 17 in 2009. It was a humiliation nightmare at first since I was dressed, bathed and assisted with toilet needs. Even though aunt Sara bathed me Harry assisted her often and Harry saw me naked several times each week. After a year or so my modesty subsided and the embarrassment lessened. In 2012 aunt Sara died and the talk was that I would move back with my mother. She was to febble and weak to care for me so I ended up staying with Harry. I think because of his age and the fact he had seen me naked so often I was no longer humiliated being nude in front of him. He became even more attentive to me than aunt Sara and to be honest I began to enjoy it. I just let him dress and undress me and let him give me a bath. When aunt Sara was alive he was always dressed but a few months went by and he seemed to be in his underware more often, which I didn't mind. What I did start to realize is that he would get erections when undressing me and especially when he was giving me a bath and washing my body. There are many times its not necesssary for him to bathe me but he always asks if I need him to and even though I don't need assistance I let him wash me. It arouses me the way he washes my breasts and vagina and I masturbate as soon as I am back in bed and wonder if Harry is doing the same. I have never seen Harry naked but when he bathes me now, acting like its a chore, he is always in his underware and its obvious to me he has an erection. I have gone from a totally embarrassed teenage to where I get aroused just knowing Harry sees me naked and more aroused when he is bathing me. I suppose also that he enjoys it as much as I do since everyday he asks what assistance I need. I'm not even embarrassed when I ask him to bathe me and he is always agreeable to do it. Shame on me but it is only sexual satisfaction I have.
