Chubby daddy with my smooth ass

This man today touch my ass in bathroom and he like it!
I noticed it in the locker room and followed him into the shower. I was very afraid. I got in the booth across from him and watched. I pretended that bathe. After some minutes of he wanted to wash his back but could not get it. my heart was pounding, I did not know how to speak to him. When he washed his back, he looked at me and saw my were my eyes was. my heart stopped! I did not know what to do and he said -can you help me wash my back? I looked around in the shower- it was just us. I said "yes, why not" took a washcloth and began soaping his back.i don't touched him back, only shoap him , but then on 1 second i try to shoap his ass. I did it carefully, afraid that he would not like but he remained silent! I slowly began to lather his ass. Then he turned and took a sponge and said "thank you" with excitement. I was offended that we did not play with each ather, but maybe he does not like boys 16 years with the elastic ass. But when I turned around - he hit me on the ass and said "very cool ass"
Nice day)
