Aunt Jacked Me off in the Shower

This really happened to me while on vacation in South Africa. We arrived at my moms sisters house near Durban, South Africa. It was a really hot and muggy summer afternoon. After we arrived, all sweaty and dirty from a long flight and car ride to a small town, I asked my aunt if she could show me the shower as I really needed to take one. I was probably 16years old at the time.   I asked her if she had a type of brush with a long handle to wash my back. I explained I had recently hurt my shoulder and it would be impossible for me to wash my back without one.   She looked at me sympathetically and said she did not have one, but if I didn't mind, she would come in and scrub my back for me.  Let me be clear, this was the time in my life I had just discovered masterbating, and also about the time I developed the biggest urge to show off my dick to any woman that would look at it.   So anyways, I said that would be great if she could help me, again thinking to myself that no woman had ever seen me naked aside from my mom and sister.   My aunt took me to the back side of the house where there was a large room with a shower.   She told me to get undressed outside and to go inside, so I stood in front of her and took off my shirt and pants.   She asked me, "aren't you going to take off your underwear?"   I pretended to be ashamed, and explained to her that only my mom had seen me naked before.   She told me not to worry, she had 4 sons and I didn't have anything she didn't see or touch before.   So I turned to face her, and slowly slipped my underwear off down to my ankles and kicked them off. She looked at my body and said, "see, its no big deal, now come here and let me start washing you".   She turned the water on and I stood under it, it was a magnificient feeling as the cool water poured over me and dripped down off my arms and legs, and my growing dick and low hanging balls.   I was in heaven.   As she started washing me, my dick stood to full attention, rock solid and 7 inches straight out. She looked down and jokingly said, "now I see why you wanted me to give you a bath, your pee pee is so big and hard, come here and let me do something for you". She then took a nice handful of shampoo and in a similar way you would milk a cow, she started pulling my dick, and balls.    At one point, she had grabbed my balls and accidentally grinded them into each other, I let out an "oof! auntie you squeezed my balls into each other!"  She said "Oh, sorry baby, I didn't mean to do that" as she gently cupped my balls in her hand and looked me directly in the eye and said she would make it up to me if I still wanted her to.   I said, "yes, but I like the feeling when you squeeze my balls a little bit".   She smiled at me and said ok, so with her left hand she took a firm grip on my balls without squeezing too hard, and with her right hand she started pumping my hard-as-a-rock dick.    It wasn't more than a minute later that I was saying, "i'm almost there!! please squeeze my balls harder".   So she started squeezing them harder and 2 seconds later I ejaculated 6 good squirts of cum 4 feet in front of me.   She kept pumping and squeezing until every last drop was out. I collapsed on the floor, winded by the best orgasm I ever had
