My focus was on the highway when I felt her hand in my crotch. I looked over at her quickly, then to the backseat where her father slept, silently asking her what she was thinking. She winked at me.
Her hand massaged my cock through my shorts as I rose to attention. It was getting more difficult to focus on driving.
She undid my zipper as quietly as she possibly could. Keeping one eye on her sleeping father and the other on my now fully exposed dick, she began to stroke me. She leaned over and whispered, "I think you know what I want." I most certainly did.
Her strokes got faster and more aggressive and my concentration shifted from the road to the growing pressure in my balls. I kept my vision dead ahead though until she got my attention with a squeeze of my cock. I looked over at her. She had unzipped her own shorts and had her other hand buried inside them. The look on her face told me she had her fingers buried in her own pussy.
I looked down to see her fingers, obscured by her panties, working in and out of her tight hole as she jerked my dick. She removed her hand from her shorts and showed me her index and middle finger. They were slick with her juices. She took them into her own mouth, showing me as she licked up all of her own nectar. She deepthroated her two fingers, gagging softly on them.
She then buried them right back into the hole where they'd been before, working herself to an orgasm. Her eyes closed and she held her breath as she came, her legs twitching slightly in the passenger seat. When she had recovered, she looked at me and smiled.
This time when she removed her glistening fingers, she pressed them to my lips as I drove. I took them in my mouth and tasted her tangy pussy juices. She forced her fingers into my mouth and down my throat as far as she could get them, all the while jerking me off.
She took her hand off my dick and brought it to her mouth, spitting in it to lube it up. She then started masturbating me in earnest, focusing all of her energy on making me cum for her. I obliged, exploding into her hands as she tried desperately not to let it make too much of a mess. My vision blurred and I almost lost control of the car as the hot mess came out of me.
As my orgasm subsided, I looked at her. She began to lick my cum from her fingers, but there was just too much for her. She grabbed a napkin from her glove compartment and wiped clean what she couldn't take herself.
In the backseat, her father snored.
