When my youngest daughter was born prematurely, we kept her crib in our bedroom. She awakened frequently, so night time was usually out of the question for sex. During the day when she took a nap, we'd have our teenage daughter babysit, while we 'went to the store.'
We'd really go parking. One day, we were both so horny, and were trying to find an isolated place, and my husband suggested I get started alone, since we didn't have much time. I removed my shorts and panties while he was driving and propped my leg up over the seat. I loved teasing him and he could barely watch the road.
He finally pulled over at the end of a quiet street as I spread my wet pussy out for him to see. I was swollen and red already with a hard clit peeping out. My labia are long and I pulled on them and spread them out like a butterfly. Then I dipped two of my fingers in my wet hole and spread my wetness all over my slit. Finally, I started working my clit back and forth, slowly at first then increasing in speed and pressure.
He finally took his hard dick out of his jeans and started jacking off. I'd never seen him so horny. It made my pussy twitch with excitement. My fingers blurred so quickly over my clit hood as I finally threw my head back and enjoyed my orgasm. My pussy was contracting hard and I felt warmth. I raised my head and saw he'd shot his cum all over my leg and pussy.
Since then masturbating for each other is a regular part of our sex life.
