They stood in the kitchen, Jake, and his mom. Jake was 19, blonde, tall, and by most standards handsome, he played in the same tennis team as his mom, her name was Ronna, she was tall too about 5'10, long blonde hair, fantastic green eyes, 38 years old, and a pair of legs, and a firm tanned ass to die for. Jake walked down the stairs, and as he entered the kitchen he got a great look at the tops of his mom's thighs as she bent over the table to gather her racket and a drink bottle, he could almost see her panties, his 8 inch shaved cock and balls twitched at the thought of her tanned ass, he hoped she was wearing thong panties today, if she was his mind surely wasn't going to be on winning a tennis match.
Jake and Ronna hopped into the car, Ronna was driving, as she sat down, Jake had a great look at her thighs again, and just a hint of her panties, black, seemed like lycra, he knew it was a thong, he had jacked off with her panties wrapped in his fist many times, he often pumped away with his fist entwined in her thong, as he thought about her sexy ass, his thick, fat cock would eventually twitch and spew cum over her black thong, and he'd have to wash it before he put it back in the wash basket.
Soon they were at the courts, Jake paired with his mom in the first mixed doubles game, he served first, she stood at net, as she bent in anticipation of his serve, he had a great glimpse at the bottom of her ass cheeks, his cock hardened as he saw was quite correct, she was wearing a thong, the bottom of her tanned ass cheeks just sat there, he served a fault... and another....double fault...
His mom looked back at him in annoyance, and Jake forced him self to concentrate on the game, they lost the first 3 games, but, an Hour later they had won, a close game, he shook hands, and went to the toilet to freshen up, he didn't have another game for 40 minutes or so.
As he made his way to the toilet block, which was situated about 400 yards from the courts, he noticed his mom following him, she ran top catch up with him, and asked if he could join her in the training room and help her out with a cramp, he agreed at once, thinking only of her hot firm ass. They neared the toilet block, and she lead him to the training room, she lay face down on the main bench and indicated that her hamstring was the problem area.
