I guess she thought of me as her younger brother.She only used to wear a loose shirt and shorts at home. She was that comfortable. When she bent to pi...k up anything, her cleavage would be clearly visible.And let me tell you, she had really huge melons. I would get instant hard-ons. I even saw her panties through her shorts a couple of times when she used to sit down. I had no other choice but to run to the bathroom and ease my bunny (penis) ????????????.I used to click her photos when the fan. I'd glue my eyes to her breasts, waiting for that special jiggle they'd display when her rifle went off. Shooting excited her too, and her nipples would get hard. There were a number of times I suspected she wasn't wearing a bra, but her breasts were so firm that it was hard to tell unless a nipple popped up.I had given up feeling guilty about lusting after her. She paid no attention to me at all in the sense she was completely comfortable around me. If she caught me staring at her she might. We did our set and did some jam sessions then hung around late with other folk people playing and talking. We did some drinking too. The two folk ladies that played before us were there also. These two ladies looked like "Dr. Laura" if you know who she is. Their names were Beth and Kate. They were not bad looking for their age but still old enough to be our mother. The next day, Saturday, those ladies played with us and it was a big hit. We played several sets during the day and then late into. Liz touched her hips and lowered her silk panties until she stood naked in all her glory in front of Santa, four elves, and Mike. Mike tried to wiggle his cock in a better position as Santa told Liz, "Come sit on Santa's lap". His red satin trimmed in white fur pants disappeared and a large cock arched upward. Liz sat across his lap and gasped as his tool split her pussy lips. Santa's beard moved as he blew out a large breath of air. Liz rocked back and forth across his lap as she became.
