Then Kelsey would giggle at something on the television or maybe at the spectacle that her mother and I were being and I would let my hand drop away. ... would glance over at my teenage student guiltily and sometimes she met my gaze with a smile or a faintly interested expression and other times she was focused on the television, laughing or taking a sip of her soda.Finally, she sat up in her recliner and clicked the television off with her remote. "I'm going to bed," she announced. She marched. I'd made myself a bet about the skirt – tight or not – and I won. The instructions called for a short skirt, but pleated and loose. With him, and me as well, I knew the possibility of exposure would win out over the purely visual appeal of something that hugged my ass.On top, a white front-buttoning blouse, preferably cotton. OK, I had plenty of those, and I guess I also knew why he wanted a dark-coloured bra. Besides the visibility of my lingerie, buttons, just like zippers, left the thought. When the pizza was gone we all jumped out of the car, each with a blanket or two, and we ran down toward the waterline. There were fire pits built into the ground and we found enough sticks and wood to build a small fire. The four of us dropped our blankets and ran down to the lake, where Brad and I tried to teach Lindsey and Missy how to skip stones on the water. Their efforts were pitiful, and we all ended up falling on the frozen sand, laughing until our sides ached. As we were lying there. An idea bursts into my mind and I reach over, grabbing Matt's hand. "I know that I shouldn't be doing this, it wasn't too much of a big deal, but I think you deserve a prize for doing that. Come with me." I tell him and his face lightens up so much, I can see sparks coming from the top of his head. As I stand up, I pull him up by the hand and he smacks into my breasts and they jiggle, making him grin. Walking out of the hot tub, we both walk across the white tiled floor toward the changing.
