"Don't you dare!" Dad shot back. "Those two asleep is the only peace we'll get on this trip. We'll be stopping for lunch soon. Just let 'em be."
"We can't leave them alone."
"Natalie," Dad said exasperated. "They're eighteen, not eight. Anybody tries to take those two deserves what they get. They'll be fine." He grabbed the morning paper stowed in the carrying net behind the seat and opened the driver's door. I watched them exit the van and walk over to the sidewalk. Dad had the paper crammed under his right arm that held his empty coffee cup while tugging the seat of his Bermuda shorts with his left hand freeing his boxers from his crack. Mom swatted his had away as if someone they may know might suddenly drive by. Anyone watching them knew they would stay together until death did them part.
I watched as they meandered up the stone path to the ugly stone and stucco building. I looked to my right at Hannah, who had wisely turned her swivel seat around facing the back of the van before we departed. Knowing the air conditioning ban we were both dressed in bare minimums. I was wearing only swim trunks and she was wearing her red polka dot bikini briefs and a cut off grey tank top with Bugs Bunny on the front with a caption saying 'What's Up, Doc?" She wasn't wearing a bra but she didn't need one. Hannah's tits where only an 'A' size, but they were perky and perfect and her hard nipples poked out against the worn fabric. Her tan legs were stretched out on the bench seat behind us. Her long blonde hair was covering her right arm that her head was resting on. The white cord of her headphones spilled out below and I could hear but not make out what song she was listening to. It was just loud enough to drown out Mom and Dad.
I considered my options. I knew I wouldn't go back to sleep and I should get out and stretch my legs. I could even stand to take a piss but, in the time it would take to put on my tennis shoes and make the journey up to rest center, Dad would already have rendered the facilities uninhabitable to anyone without assisted breathing devices.
All of the side windows were popped open and there was a humid but strong breeze blowing through. I glanced out at the three other vehicles, of which the farthest from us was inhabited by an oversized man stretched back sleeping, his left hand resting on his crotch, his right hand resting inside a bag of Doritos. The car beside his was empty, the occupants no doubt inside. The third was a Winnebago parked on the opposite side of the lot taking up four spaces. An elderly man and woman were walking a mangy looking poodle that would no doubt precede both of them in death, probably soon considering the painful way it walked looking for a place to relieve itself.
I looked back over at my twin sister in her white rimmed shades. She hadn't moved since I woke up. I relaxed in my seat deciding to wait for Mom and Dad to return and folded my hands across my stomach. I looked down at my feet resting on the folded beach towel on top the cooler in front of me and watched as the tent slowly rose in my swim trunks.
I hadn't jerked off since yesterday morning. After we had spent the day packing and preparing for the predawn departure I was exhausted and fell asleep early. I knew by the time we reached our beach house later that evening I would have a severe case of blue balls.
I pulled the waist band of my shorts up with my right and looked at my thick, semi-hard cock. When I measured it last week, it was six point nine inches long. I was really hoping for a full seven inches, but was satisfied what I had. I glanced once more outside at over at Hannah, then wrapped my left hand around the shaft. I stroked until it was completely hard then put my feet on the floor and lifted my hips. I pulled my shorts down to my knees and with my free right hand, I cupped my balls. I closed my eyes and started jerking off.
I squeezed my shaft and tugged my balls, feeling them getting tighter when, all at once, I felt a hand grab my trunks and jerk them down my legs and off my feet. My eyes popped open and I saw Hannah on her knees in front of me. Like a cat, I never heard or saw her move. She had pushed her shades on top of her hair like a braid. "What the fuck?" I said. She just smiled and said, "I got this, bro."
She pulled my hands away and took my hard cock in her left hand slowly jerking the shaft. She leaned forward and took my right ball in her hot, wet mouth. She sucked it deep while running her tongue all over it, massaging my left ball with her right hand. Once the right ball was saturated with her saliva, she sucked the left one in, running her tongue back and forth between them both, sucking them deep in her mouth. I pushed her gold hair back and caressed her shoulders looping my fingers around the straps of her tank top.
As I pulled her shirt off, Hannah released my balls from her mouth, cupping them in her right hand, tugging them with her fingers. She put her tongue on the base of my dick and slowly began working her way up the shaft. When she reached the head, she licked the pre-cum dribbling from my slit, then took the tip in her lips. She squeezed and jerked my shaft tight as she licked my throbbing head over and over, making me moan with pleasure. Then she began swallowing the whole shaft down her throat.
Hannah was sucking my dick like it was the most delicious piece of candy she ever had. Sweat was dripping off my ass onto the striped beach towel covering my faux leather seat and I was bucking my hips in motion with her bobbing head. She hooked her thumbs in her bikini shorts and slipped them off, then straddled my lap as I leaned the seat back. She took my throbbing cock in her hand and pushed the head against her slick slit. I jerked involuntarily at how hot her pussy was as she lowered herself on top of me.
