After the bath incident where I jerked my uncle and almost made him cum with my mouth, things had went to normal in the house. I would stay with my grandparents for five more weeks while my Uncle Pedro had his arms in casts after a car accident. I haven't had any other incident with my uncle, but I wanted to. I could not forget his monster cock and how much he came. I could not forget having his pulsating meat inside my mouth leaking pre-cum. At night, I would finger myself slowly remembering his cock until I reached an intense orgasm. I wanted to feel him cumming in my mouth, I wanted that cock inside my pussy, I wanted him. I knew it was wrong, but I would make him fuck me before I went back to New York.
Three weeks after the incident, my grandparents had to go back to the capital for a week. Again I would be taking care of my uncle and this time my cousin Sheila was staying with us. Sheila is a year older than me and very different from me. She is a tall woman, about 5 feet 10 inches tall, with clear skin, and kind of a tomboy, although a very feminine one. She never uses make-up and she had cut her brown hair very short. If you did not see her nice hips and big 38-D breasts, you would think she was a guy. I haven't seen her since before the incident and I was debating if telling her about what happened.
My grandparents left and Sheila and I began chatting about my vacations and about taking care of uncle Pedro. He was also her uncle -- her mother was my aunt -- and she also believed he was handsome as hell. I haven't told her about my adventure with him, and I decided to not tell her anything. Besides, she would not believe me...
The day after my grandparents left, I noticed my uncle trying to scratch his part with a stick. The previous week the casts on his arms went all the way to his shoulders, now they had been replaced with casts that only reached his elbows. He had a lot more mobility, but still needed assistance to bath and eat.
"Uncle, are you OK?" I asked knowing the answer.
"No, Mariela, I'm not" he answered in an exasperated voice "I need to clean my privates again, there had been like four days since the last time Dad cleaned them, and I can't deal with it!"
"Come on, uncle, it's time for a bath!" I answered and grabbed him. I prepared the bath as I did the last time, but this time he was able to take off his pants by himself. He sat in the same place as I began to wash him with the sponge. This time, his erection did not surprise me and he was looking at me at all times. I could feel his eyes on my cleavage, generously visible thanks to my tank top. That attention and seeing his enormous stick pulsating turned me on. My pussy began getting wet and my nipples wanted to pierce the fabric of my top. When it was time to wash his privates, he told me "Please, do it like the last time... with your hands" I smiled and complied, stroking his meat slowly. I knew what I wanted and it was his cock exploding inside my mouth, so I cleaned his privates and told him to stand up to clean his back. He looked surprised, but I told him that I had a better idea, so he stood up.
