As I pulled the car onto the highway I looked over to my wife sitting in the passenger seat.
"What are you grinning about?"
It was a warm spring day. She was wearing a turquoise tank top, a flowing skirt down to her knees, and sandals. She slid down in the seat a little and spread her legs.
"You're not wearing panties?"
"Maybe. Do you want me to be not wearing panties?"
I smiled and reached over to her crotch but she slapped my hand away. "Pay attention to the road!"
She put her own hands down between her thighs and began to rub herself.
"Mmmmmm . . . feels good . . . feels smooth."
She reached down and slowly pulled up the thin fabric revealing her naked pussy. To my astonishment I could see she had shaved herself bald. Her white creamy flesh glowed in the sunlight. Her index finger slowly split her slit as it moved up and down.
"I like feeling the warmth of the sun on my pussy," she said as she put both hands down between her legs and spread her pink lips. "I'm feeling good. Are you feeling good?"
I mostly paid attention to my driving stealing glances of her masturbating in the seat to my right. There was no denying pressure of my cock straining against my pants. I reached down to readjust it as we approached the bridge toll booth.
"Toll booth honey."
"So," she said had she slid down further and opened her legs wider. She now had her fingers buried in her cunt pumping herself a little faster. Her hips squirmed in the seat as she savored the sensations of open air masturbation.
I pulled up to the booth. It was a guy in the booth already counting out change for a twenty. I struggled to pull my wallet out for the fare. It certainly wasn't made any easier by having a raging hard. As we exchanged bills he woke up to the sight before him. I doubt he could see her face from his vantage point but he sure as hell could see my wife's hand pumping her wet pussy. The car was filling with the musky scent of her sex. The attendant smiled and nodded. I wondered how many freaky things he sees in cars each day.
My wife, Diana, is 49 and I'm 51 and sex has been good over the years. It got really good 11 years ago when I got a vasectomy and we were no longer constrained by the ordeal of gels and diaphragms. Until recently our sex has been fairly conventional; in the house with the occasional fuck in the back yard on warm afternoons. I especially liked the backyard sex though it made my wife a little nervous that people on the sidewalk might hear us through the fence. But that's the point, isn't it? The possibility of exposure? The idea that somebody else might unexpectedly get turned on by our pleasure?
Lately though, for reasons I haven't figured out yet, she has been loosening up. I came home two weeks ago to Diana dressed in a black lacy bra pushing up her small tits, black boyshort panties, and red high heel slippers. She looked stunning. When she turned around and bent over to show me her pussy lips protruding through the crotchless panel that was all I needed. I dropped my pants and fucked her hard from behind as she leaned against a living room chair. Then last weekend I dropped my motorcycle off at the dealers to be worked on. Diana followed me 15 minutes later to pick me up. She was wearing a long coat but nothing else leading to another furious fuck went we got back into the house. Now here she was again pushing the edges of our sexual routine.
"Are we still going shopping?"
Diana sat up and spread her skirt back down over her thighs. She put her fingers into her mouth and tasted herself then wiped her hand on her skirt.
"Sure. Unless you have something better in mind," she said.
We were heading to the new chic upscale mall in the city. The thought of her strolling commando among throngs of shoppers was appealing. There were possibilities for the dressing rooms in the clothing stores or a little "exposure" while shopping for shoes. But I decided the best way to take advantage of her mood was to head to North Beach. There were some stores there and some outdoor cafes and another place I thought might be perfect if I can convince her to go in.
It was a spring Sunday afternoon so there were lots of people taking advantage of the good weather. Probably not the way Diana was taking advantage of the good weather though. Parking was tough but I found a spot on a leafy side street reasonably close to commercial district. As I parallel parked I could see that sidewalks were pretty empty here. As I switched off the motor Diana reached over and put her hand on my crotch.
"Still got your hard on?"
I didn't but it was coming back quickly.
"Here?"
"Whip it out. Quick. While I'm still game for this."
I slid the seat back as far as it would go. She undid my belt, unbuttoned my jeans, pulled down my zipper and yanked my hardening cock out into the open.
"Keep a lookout," she said nervously and then she went down on my dick.
I have to admit I was a little nervous myself. We had never had sex in "public" and here it was bright and sunny in the city and Diana was bobbing up and down on my cock. My shaft was glistening with her saliva. I could feel her tongue caressing the underside of the head. I saw a couple of tourists on the opposite side of the street but they were having a normal conversion. Not looking into cars to see if anyone was getting a blow job. I could feel my cock getting wetter as her tongue did its work on me. She lifted her head to look around and I could feel the cool air on my wet cock.
"Uh oh. Someone's coming."
I reluctantly shoved my cock back into my pants and zipped up. I gave Diana a big kiss and we got out to go "shopping". The couple had walked by and were a little ahead of us. I took this chance to run my hand over Diana's ample ass. I could feel her smooth cheeks through the thin fabric of her skirt. She pushed her ass back against my hand playfully and smiled.
"How's it feel walking out here like this?"
"Naughty. And I can feel the cool air on my wet pussy. It's nice."
We strolled the business district among the throngs of tourists and locals. We window shopped the few trendy clothing stores in the area. Diana looked great for her age. Thin. Blonde hair cut in a bob. Since her tits were so small she never wore a bra but you could see she was excited from the sight of her stiff nipples clearly visible through her tank top. I had never seen them so hard and prominent. Her skirt flowed around her legs and in the right backlight you could see her bare legs through the shear fabric.
We sat at one of the outdoor tables of an Italian café and people watched while Diana sipped her cappuccino and I an Italian soda. She sat behind the small round table. I reached over to her lap. She put her hand on mine, "What do you think you're doing?"
