My only guess was age.We quickly unloaded the food into the coolers and started scraping the ice. she would scrape into a bucket and I would empty it....Today she was wearing one of her oldest "wife beaters" with no bra and a loose pair of old sweats she had cut off into shorts. Not exactly a teddy, right? But the sight of her breasts swaying back and forth as she scraped, and the bottom of her butt cheeks showing as she was bent over was getting to me.Her nipples were drawn and hard as a rock. Her head shot up, mouth wide open too shocked to speak. Her hand reached around and caught one of my ass cheeks. She gripped it and as though she was reading my mind she purred, ‘Cum in my pussy now, baby!’ As though on cue I began to bust. ‘OH FUCK! OH FUCK! GOD I’M COMING!’ I couldn’t move, but without missing a beat Mrs. Ivery began to take control, thrusting her pussy further down the shaft of my 7 inch cock. Mrs. Ivery collapsed to the bed, her breathing was labored again and I can’t say. I dropped my towel in the sand and walked right into the water and dove in. I came up gasping and groaning at the temperature of the lake. I took a few strokes out into deeper water and just floated on my back trying to ignore the cold.I became aware of hooting and hollering coming from Harvey's pontoon tied to his dock next door. I looked over and saw mom, Sam and another woman I thought must be Casey pointing and laughing at me.I walked back onto shore and grabbed my towel and dried myself. My own cock was hard again, thinking about making my sister’s boyfriend cum. I took the lube from the nightstand and squeezed some onto my hand. Joe gasped at the cold when I took hold of him, but was soon moaning in pleasure as I stroked him. I looked over; Sarah had one of her legs hooked over the arm of her chair, and was slowly working two fingers in and out of her pussy. Her eyes were fixated on Joe’s cock in my hand. Well, I thought, might as well give her a show. I slowly sucked Joe’s.
