My wife and I vacationed this past winter at a water park resort. She has taken good care of herself over the years, and has long blonde hair, 32b-26-34, 125 lbs, and light brown puffy areola and 1/2 inch eraser size nipples. At this resort women are allowed to go topless if they so desire to.
After we arrived and checked in, my wife changed into her small bikini and wanted to head over to have a swim in the water park area. I told her to go ahead and that I would be along at bit later, so she went on by herself. About 20 minutes later, I arrived at the water park area, and found that men had to enter through the men's locker room and women through the women's locker room. There were about 40-50 others people in the water park so it was not real crowded, and most of them were in their 50's or 60's as this was a time of year when snowbirds came down from the northern states and vacationed where we were. Most appeared to be couples, no families or children anywhere, and a few single men and women, mostly in their 30's or 40's.
Shortly after I arrived in the water park, and as I was watching my wife who was in water at the wave pool in about four feet deep water, when the wave pool started. I watched as she began jumping as the wave motions increased, but she timed her fourth or fifth jumps wrong and would up with a mouthful and nose full of water. The next wave went over her head and I was about to get up and go rescue her, when a man close to her and who looked about her age did exactly that.
He maneuvered over to her, and wrapped his left arm around her body and breast. He began jumping with her and in rhythm with the wave, continuing to hold her breast with his left arm, maneuvering her so that her back was to the others in the pool as well as to me. In this manner, he was able to fondle her right breast with his left hand. I watched as he then placed his free hand on her back where her bikini top was tied together. As they jumped together, he managed to untied my wifes bikini top, and slid her top off, and letting it go free with the waves moving her top far away from them.
My wife didn't appear to notice her top was now missing as she apparently was more concerned about not being dunked under the waves again, and making sure her jumps were in rhythm with the waves. The stranger continued to help her with this, as he now placed his right arm around her naked breasts as well. He had his left hand on her right breast and his right hand on her left breast, now fondling both of her breasts.
The wave pool went on for another 5 or 6 minutes, with him holding her breasts firmly and jumping with her the entire time. When the wave finally ended, they stood there together a few more minutes with him holding her breasts until she finally stopped sneezing and coughing from the water. He let her go at that point, and at first she didn't appear to recognize that she was completely topless.
