After surgery I couldn't wash myself so I had help
I enjoy being naked in front of women and watch their reactions at male nudity while being dressed. I rarely have the opportunity to do this as I do not want to scare or offend unwilling women.
I recently had surgery on my shoulder and arm which restricted my ability to do simple tasks like wash myself, and masturbate, until I got used to using my left hand. My wife did not feel comfortable changing my dressings, so she asked her sister to come over to help.
After she changed the bandages, my wife suggested a shower before I got dressed again. I was surprised when my sister in law, Jenny, volunteered to help and walked me to the bathroom with my wife. My wife pulled my pants down and started the water, it takes a few minutes to heat up, so there I am completely naked in front of my wife and her sister. This is a fantasy I have wanted for a long time, but I did not want to ruin the moment so I tried thinking every non sexual thought to avoid getting hard. I did notice Jenny looking at my penis and smiling a little which did not help.
I finally got in the shower and Jenny soaped up a washcloth and started washing me, I could not help starting to harden up, especially when she spent a few extra seconds washing my dick and balls. My wife did not seem to notice anything as she just kept talking to us, until Jenny commented how I was beginning to enjoy the shower. My wife looked and smiled and asked what I was going to do with that thing, I said nothing as my right arm was immobile.
Jenny started to rinse me off again teasing with the spray on my dick a little too long. They helped me out of the shower and dried me off, and continued to talk as I stood there nude and hard as a rock hoping something would happen. They would both take a peek at me but pretended to ignore my situation.
Finally my wife took me into the bedroom and sat me down to get me dressed, I assumed Jenny went back to the kitchen to wait for us. As my wife started to dress me she asked if I needed anything else, I nodded to my hardon and said a little relief. She smiled and started to play with my balls, and stroke my dick, I was in heaven having one of my fantasies come true.
As I laid back and enjoyed the hand job I noticed movement by the door and realized Jenny was watching us, my wife did not seem to know she was putting on a show for her sister. She licked my dick to get it wet, and the thought of being naked and jerked off in front of two clothed women made me explode almost immediately.
After that I saw Jenny's head disappear and my wife wiped me down and finished dressing me. I do not know if the sisters planned it or if Jenny knows I saw her watching but it was great, and I mentioned to my wife that I need another shower real soon.
