Earlier this summer I went to visit and help my aunt and uncle who are both in their early 70's. Aunt Doris is usually busy with various women's clubs and uncle Jack is home since he suffered a mild stroke last year and needs help from time to time.
About a week after I went to help, Aunt Doris left one day to play cards and instructed me to help Uncle Jack take a bath and get dressed. After she left, I helped uncle Jack into the bathroom where he dropped his robe and got into the large shower. He had a little trouble standing but held onto the safety bar as I turned on the water. He asked me to soap him up and I began to soap his back and chest. I knew I would get wet so had put on my bikini and got into the shower with him. As I washed his chest I noticed that his penis started to get erect. Uncle Jack is a small, thin man but as his penis continued to swell I was amazed at how big it got. I was embarrassed and tried not to look but couldn't help it. I think he was nervous but finally asked me if I could wash his 'business'. I said, 'uncle Jack, do you think I should?' and he said 'please Cassie, I won't say anything to Doris.'
I lathered up my hand and gently began to wash and rub his penis which was now fully erect and throbbing with excitement. As I washed him he kept saying, 'Oh god Cassie, that feels good, don't stop.' I rinsed him off and got some baby oil from the shelf and poured some over his bobbing penis. He said, 'Please Cassie, make me cum, it has been so long.' I felt so sorry for him yet I was getting horny looking at his big erect penis and stroking it with the baby oil. It took almost ten minutes of stroking before he grunted and started to ejaculate. For an old man, I was amazed at the amount of semen that squirted out of the end of his big penis and onto the shower floor. When he was done, I cleaned him up, dried him, and helped him get dressed. He thanked me and swore me to secrecy. After he got set in his chair I went back to the shower, stripped, and fingered my clit until I had a giant orgasm.
During the month I stayed with my aunt and uncle the scenario repeated itself at least four more times when I bathed uncle Jack after aunt Doris left to play cards. On the last two occasions I got naked in the shower with Uncle Jack and let him masturbate me while I jacked him off.
