Shirley was getting frustrated. She was trying to teach her son, Tom, to drive but he wasn't concentrating. Every time she looked at him he seemed to be watching her instead of the parking lot. Shirley was already concerned with his progress. Tom was the quintessential nerd and at 18 still hadn't learned how to drive. She swore she'd teach him, she just needed to find the right motivation.
The heat didn't help either. It had to be 95 out today. Too bad the air conditioner was broke in this car but Tom had to learn how to use a clutch.
Although she wore a light cotton sundress she was still sweating. She had the bottom pulled up around her thighs to get some air. Shirley wore no bra but her 34 D's still looked firm as a teenagers showing off her cleavage in this dress. Tom didn't look any cooler in his tank top and loose shorts. She hadn't noticed how well he had developed lately. His arms were tan and strong and his thighs were quite large and firm. Shirley saw that his shirt had soaked up enough sweat to let her see his nipples against the white fabric. As she looked she noticed something else was large and firm in his shorts. Now she was having trouble concentrating. Thinking about a firm hard body like that next to her, on top of her.... Kerkunk!! The car complained as Tom slipped the clutch out wrong again. Shirley looked into his face to see him staring at her chest. She could feel the object of his attention. A bead of sweat had rolled off her neck and was making a slow teasing crawl down her chest to slide between her breast. Had he been watching her as she watched him? Was it his mother he was thinking about or a girlfriend? Shirley noticed Tom's face grow red when he knew he was caught. Her breath faltered as she realized it was her he had been thinking about.
"Maybe we need to try something different." Shirley suggested. "Let me slide over there on your lap and I'll guide your way."
Tom wasn't too sure about this. His cock was already hard from watching his mother's breast jiggle as he popped the clutch. Having her sit on it might be too much for him.
Shirley had started moving before he could protest. She removed her shoes to help push his feet. She held onto his thighs for support and marveled at their musculature. She placed her legs on either side of his and could feel his heat. As she lowered herself his cock rubbed against her ass and slid down between her thighs. Shirley moaned lightly as she felt this. She knew she couldn't last long like this and wondered about the sanity and morality of what she was doing. Her husband had always been good to her and the sex wasn't a problem so why was she so worked up over her son.
'Maybe if we stop now it will be ok' She thought. But as she settled down Tom laid his hands on her thighs and squeezed. His thumb rubbing the inside inches from her moist pussy. Shirley couldn't stop now if her husband was watching. She slid her right hand over his and squeezed again.
" Shall we try it my way?" she purred. They lifted their hands to the gearshift and moved their feet to the pedals.
Shirley turned her head so she was whispering in his ear. "The trick is to do it slow and gentle. You have to get the feel of how she wants it. Do you understand?"
She felt his cock grow harder underneath her as he nodded.
