"We're fine," Vicky said, as she began, much to my surprise, slowly riding my dick without their notice.
"Yeah, just keep driving and get us there," I added, trying to act casual,
I just sat there and enjoyed the pleasure of my step sister, slowly riding my dick, as I gently rubbed her back.
"Mmmmm," she let out a moan as she took my entire cock back into her wetness.
I whispered, "Take your time."
She nodded, as she again closed her eyes.
God, I wished I could see her face clearly. I wished I could see her naked body as she rode me.
Wanting to be more a part of this surreal moment, I leaned forward and cupped both her breasts... wishing she wasn't wearing a bra.
As if reading my mind, she stopped riding me, again sitting completely on my lap and moved my hands away... at first I was disappointed, but that was short lived as she lifted up her shirt, unclasped her bra and tossed it to the ground.
I returned my hands, this time under her shirt, to her breasts and traced over her incredible hard nipples.
Her body trembled at my gentle touch, even as she resumed slowly riding me.
God, I wanted to suck those big tits... those hard nipples.
I was brought out of my lustful thoughts, as Dad warned, "Rough patch coming."
"Thanks for the warning," Vicky said, as she lifted her ass up, holding onto Dad's chair, looked back at me and mouthed, "Fuck me bitch."
I didn't hesitate, as I moved my hands for balance away from those perfect tits and began slowly bucking my ass up.
This time she looked at me throughout, which only enhanced the intensity of the moment. Pushing it past just being sex to something else... something I couldn't explain... couldn't rationalize.
"Faster," she mouthed, just as the car began to vibrate from the roughness... which made me think back to the washing machine.
As if thinking something similar, she leaned back and kissed me, my entire dick again being lodged deep inside my stepsister.
It was soft and tender.
But sparks erupted through my very being.
Our tongues explored each other's mouth, as I again reached around with my free right hand and cupped her breast.
When she broke the kiss, she looked into my eyes with such vulnerability and lust that I loved her even more... so much that it confused me. Could I love my stepsister in a way that was more than just siblings?
She smiled and whispered, "I love you."
"I love you too," I replied, warmth coursing through my entire body at the words other girls had said to me and I lied in return... this time I meant it. This was more than just fucking... this was something else... something organic... something perfect.
"Now fuck the hell out of me," she said, the words sounding so hot and nasty coming from her sweet lips.
"Yes, ma'am," I nodded, as I put my hands on her hips, lifted her up and began fucking her, trying to be both quiet and aggressive... which was quite a challenge.
"Yes," vicky moaned, louder than she anticipated.
"What, honey?" Mom asked.
Covering quickly, even as I kept fucking her, she answered, "Just got a text that Sarah finally dumped that loser Dave."
"Oh, okay," Mom said.
For a couple of minutes, I fucked her as best I could in the awkward position I was in.
It felt so amazing, yet I couldn't get into a rhythm.
She then sat down on my lap and began riding me.
I groaned as she began bouncing on my dick, the sounds of our bodies colliding covered by the radio and the loud sounds of gravel underneath the car.
My balls began boiling, and it was clear vicky was getting close.
She was biting her lips.
Her eyes were closed.
And she was riding me as fast as she could as she again grabbed onto Dad's chair.
"You okay, honey?" Dad asked, feeling his chair pulled back.
"Never better," she answered.
"Only about thirty minutes left," he said.
"Okayyyyy," she replied, her orgasm close, another bump on the road able to hide the real intent of her moan.
"Sorry," Dad said.
"Oh, I'm getting used to being bounced around," she quipped, which made me gasp slightly at the wicked double entendre
"I'm sorry," Dad said.
Mom offered, "I could replace you back there, vicky."
I smirked at the reality of what Mom was unknowingly offering.
I'm not sure you could handle the pounding I'm taking back here."Vicky replied, as she slammed down, looking back at me with a wicked smile".
Oh fuck! God, my sister was wickedly hot.
"You sure?" Mom asked. "I don't mind the bumps."
"It's okay, Mom. I'm finally in the perfect position."
"Me too," I added.
"Okay," Mom said. "But if you want to swap positions just let me know."
"Okay," vicky smirked at me, before asking, "are you comfortable with your sister on your lap?"
"I'm handling it okay," I said.
Then she resumed riding me. Grinding her ass on me. Fucking herself.
I began bucking my ass up to meet her downward bounces and reached around and began rubbing her swollen clit, which made her gasp, "Ohhh, God, shit."
Mom said, "Pull over, Frank," which made me stop.
"No, no, keep going," she demanded with a tone that said don't you dare stop. I wasn't sure if it was aimed at me or Dad, but Dad didn't pull over, although he did slow down as I kept fucking her.
"We need to stop." Mom repeated. "They are obviously not comfortable."
"Keep driving," Vicky repeated, "I'm so close."
"What? Close to where? " Mom asked, as she moved a box to look back at us.
"She means we're so close, let's just get there," I covered for her, as she stopped just in time to not get caught riding me.
""Oh, okay," Mom said, looking at us with a perplexed look. My heart started beating.
To my surprise, Mom moved the box back to hide us and vicky resumed riding me. I became confused, I wondered if Mom knew. Vicky didn't seem to care.
