Dani fell asleep in my lap, my cock resting just inches from her lips. For the first time I saw a satisfied smile on my sister's face and knew that I had put it there. My fingers gently stroked her thigh, the heat from her sex still strong against them. I sighed happily, knowing that things between my sister and I would never be the same, and knowing that was a good thing. No more fighting, no more spending all our time at each other's throats. A lot more quality time.
I felt my eyelids start to droop, and knew I would be asleep before long. Giving my sister's perfect little breasts one last glance and running my finger across her slit one more time, I pulled my hand free of her shorts and pulled her t-shirt down over her chest. As gently as I could I lifted Dani's head and slipped the leg of my shorts back down, tucking it under her cheek. The effort exhausted me, and I fell asleep seconds later, my arm draped over her midsection.
A few hours later, I woke to the feeling of soft hands on my cock, gently stroking the length, wrapping around, squeezing and gliding up and down. I opened my eyes and was greeted by the sight of my sister giving me the best handjob of my life, lying on her stomach beside me, her eyes fixed on her work as she jacked me. I let my hand slide from the small of her back down to her ass and gave a gentle squeeze, enjoying the feel of her hands and the drone of tires on asphalt.
"I was wondering how long you'd let me molest you before you woke up," she whispered. Her smile was sexy, beautiful, and empty of the animosity it would have held just a few hours before. "Mom's awake," she warned, and turned her attention back to my cock, slipping her hands up and down the shaft in slow, deliberate motions.
"Morning, sleepy!" rang out from the front of the van. As the words left my mother's mouth, Dani swallowed my cock, taking the whole length down her throat in one fast move.
"Ah! Ah... morning Mom," I stuttered. I gently swatted Dani's ass, careful to keep my arm below where Mom could see.
"Didn't mean to startle you honey," Mom chirped. "Is your sister awake? I'm a little thirsty." Mom knew that my bulk would prevent me from handing her a soda, but that Dani had no such hindrance.
"I dunno, Mom. Let me check," I replied. I scooted my hand up from Dani's ass and slid it up under her shirt, slipping my fingers around her breast I found her nipple and pinched, pulling a loud, deep groan from my sister's cock-filled throat. "Yeah, she's awake," I called.
"Oh, good! Dani, dear, could you hand me a Diet?"
