She suddenly stood up and bent over deeply to pick something off the floor. I did not think that was the reason she did. I slipped my hand up her dres... to give her pussy a gentle squeeze. I was pleasantly surprised that her pussy was bare under her dress. I flipped up her dress over her waist and pulled her closer to me.I held her hips in my hands and licked one ass cheek first then the other. She moaned as I tickled her ass cheeks with my tongue. I licked her close to her ass crack, teasing. We both stood in silence; the only sound in the room was the water as it cascaded over our bodies and Jim’s heavy breathing and occasional groan. I trembled and looked into Jim’s eyes. “You better never tell anyone about this,” Jim scolded, “I will tell everyone that you are a sissy.”He didn’t need to tell me not to say anything, I was embarrassed yet there was an intimacy I had never known. I just made my brother cum and that seemed like I was in some way in control of him. Jim rinsed off and. I snatched the mini off the rack and headed for the changing room. I think I wandered into an obscure area of the store and found a little dressing room out of the way of the crowded scene because no one was in it and no one was around it while all the other rooms were full. “Oh well,” I thought. “Good for me!” I walked in to the room and saw there were two booths so I took the one on the left because I’m a lefty. I locked the door behind me and stripped to my panties. I pulled my sweatshirt. " I pointed toward my Aunt's house.She spread her towel next to mine "I'm Brenda. Mind if I take my suit off?" Help yourself." Not that her suit covered all that much of her anyway. Besides I was naked already.As she moved so she was not directly in the sun, I began to realize just how nice she looked, not a raving model kind of woman, but a lot like me. You know, that mid-forty year old look. Body not so firm anymore, but definitely not even close to being chubby. Her hair long, in a ponytail.
