My Pregnant Stepsister

"No," Quinn responded quickly. "No, keep going," I said. "We are finally in a comfortable position."

I decided to finally reach around and cup her breasts. She leaned her body back against mine, giving into the molestation of her big step-brother.

She began to slowly grind herself on my dick.

She grinded on me for a couple of minutes... both of us speechless as we contemplated what we were doing, what we could be doing.

Then we hit a sudden rough patch.

"Ooooooh," she moaned louder... enough to alert our parents.

"You okay?" Mom asked.

"Yeah, but could you warn us when you are going to hit a rough patch?" she requested.

"Sure, honey." Dad nodded, just as she lifted her ass up, tugged her panties aside and looked back at me with clear lustful intent.

I positioned my completely hard dick straight in the air and aimed it for her perfect pinkness as she lowered herself on my serpent... swallowing my dick completely.

Dad hit the mother of all potholes. My ass lifted up, my dick reached new depths, and Quinn screamed, "Oh my God." Dad slammed on the brakes and said, in a panic, "You okay?"

Quinn snapped, so unlike her. "I told you to warn us if you were going to hit a bump." "Sorry." Dad said in the tone usually used for when he pissed off mom. "Should I pull over?" Dad asked, going at a snail's pace now.

"No!" Quinn replied resolutely.

Mom, being the peacemaker, asked, "Are you guys okay back there?"

"We're fine." Quinn said, as she began to ride my dick slowly without their notice. "We're fine." Quinn 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." Quinn 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," Quinn moaned, louder than she anticipated.

"What, honey?" Mom asked.
