Amy woke up from a forty-five minute nap somewhere along I-88 on the way to Iowa. She opened her eyes and nuzzled into her brother's arm that she had been holding onto while she was sleeping.
"Where are we?" she asked in a yawn.
"Just passed through DeKalb." Luke kissed her head. "Did you have a good nap?"
"Oh yes, sleeping on you always brings me good rest." She lifted her head, kissed his upper arm where she was snuggled into, and then rested her head back on the headrest. "Sorry I fell asleep."
He chuckled, "I'm used to it. You used to always sleep on me during road trips." He lifted her hand that he was holding and kissed the back of it before settling their hands back on the console.
"I've always loved sleeping on you," Amy commented with a smile.
"I've always loved you sleeping on me."
She closed her eyes again, but kept her mind busy with thoughts from their afternoon rendezvous to keep herself awake. Their parents had left for their grandmother's house, which was just outside of Des Moines, mid-morning. When they arrived home after Luke picked her up from school, they checked off another place on their "tour of the house" list.
Their parents had remodeled the master bathroom last year, complete with a luxurious walk in shower. The shower stall was quite large, with glass panes, and a wide bench at the back.
After several minutes of making out and touching each other while the hot water cascaded down their bodies, Luke bent her over the bench and she squealed giddily. She had her hands settled on the porcelain with her ass presented to him. They were both thoroughly aroused from the kissing and teasing of their hands. He stepped up behind her, held her hips, and then slid his erection into her hot cunt.
They both uninhibitedly moaned out in pleasure once they were joined together again. Amy pressed herself back into him as hard as she could, begging for him to use her. He obliged, and within minutes was pounding her slick inner flesh.
Amy whimpered and squirmed at the memories. Luke looked over at her in blue Cubs hoodie that was unzipped, showing the lavender spaghetti strap tank top underneath and denim skirt that stopped a couple inches above her knees. He smiled, but kept quiet.
Her mind continued replaying the events. She felt him caressing her ass and the marks of ownership he had left there the previous evening. Her head was turned over her shoulder and she looked at his face while water was splashing against his back.
The glass walls quickly fogged up and they both had become sweaty from the heat of their bodies and the temperature of the water.
She heard herself screaming to him, "Use me, use your slutty baby sister like the piece of fuckmeat she is."
She loved talking dirty for him because it heightened the arousal for both of them. She knew how much he adored it and she would dish it out at any moment he asked for it. Words could fly out of her mouth like she was reading a memorized speech if she wanted them to.
Amy remembered feeling him throbbing inside of her, but she wasn't done yet. A quick position change would help delay his orgasm. They didn't have a lot of time, because they needed to get on the road, but they had enough.
She had him sit down on the bench, and then she mounted him in a reverse cowgirl position. He held her waist as she bounced, pulling her down onto him even more forcefully than she was already going. On every thrust, his cock bottomed out inside of her and she felt it in the pit of her stomach. The sensation made her squeal in ecstasy.
Her wet brown hair was matted to her skin and Luke had made a comment that her hair covering her nipples made her look like a beautiful mermaid. A smile curled on the corners of her lips from the memory.
Her brother had pushed her hair over one shoulder and began kissing her neck in the spot he knew that made her squirm, right where her neck and shoulder meet. He pulled her back against his chest and she spread her legs obscenely wide over his thighs. His hands greedily groped her breasts while her hips rolled in his lap, keeping him deep inside of her.
Amy kept her eyes closed and rubbed her thighs together while writhing in the passenger seat.
She remembered hearing him growl in her ear, "Cum on my cock. Let me feel my baby sister orgasm on me."
At his command, she gave in to her inevitable climax, squirting her fluids out around his thick cock. He held tight onto her as her cunt milked his shaft and her body shuddered. Moments later, his orgasm erupted inside of her, spitting volleys of his spunk inside of her cunt. When she got back to her feet, his seed trickled down her inner thighs.
Luke let go of her hand, and then reached over and ran his fingers through her long silky brunette mane. "You're thinking about the shower today, aren't you, Squirt?"
"Mmhmm," she muttered a reply. She blinked her eyes open and turned her head so she could look at him. "I'm wet again just thinking about it."
Her brother's hand ran down her body before finding her knee. He trailed his hand along her inner thigh as he spoke, "Let me feel how wet those memories made you."
Amy giggled as she pulled her skirt up. She lifted her bum off of the seat and hiked her skirt up to her hips, exposing her white and purple polka dotted thong.
His hand slid further up until it settled on her silk covered mound. He could feel her heat radiating through the fabric.
"My, my, my," he said as his fingers slid beneath her panties, "Amy Marie Davenport, what am I going to do with you?" He was greeted with her silken fluids as his fingertips pushed into her slit.
"Love me," his sister moaned as he teased her clitoris. "Love me for being yours. Love me for being so turned on by just thinking about you. I can't control it."
Luke's fingers trailed down to her cunt. There was a pool of her hot nectar at her entrance and he pushed one digit inside of her while keeping the other hand on the wheel.
He didn't look over at her as he gently pumped her with his finger. "I do love you for being mine and I always will."
Her eyes fluttered closed and she whimpered. She lifted her hips to meet his hand, not caring if anyone driving by could see. Luckily, he was in the right lane, so drivers passing on the left wouldn't get the easiest view.
Suddenly, he withdrew his finger. Amy pouted as he covered her sex with her panties.
"Pull your skirt back down, dirty slut," he said with a teasing grin. "We have five hours to go, I can't have you getting off just yet, can I?" He patted her thigh, and then brought his finger to his mouth.
She opened her eyes and shot him a playful scowl as she wiggled her skirt back down. "Fine, you win this round. But, I'll get you back for this."
Her brother sucked her fluids off of his digit, and then offered her his hand to hold. She took it and wrapped her fingers with his.
"How do you plan on getting me back?" He glanced over quickly before returning his eyes to the road.
Amy turned in her seat, facing him. She reached over and tussled his soft brown hair as she giggled, "If I tell you, you'll be expecting it." She smoothed out his hair where she had messed it up as she continued, "That wouldn't be any fun."
Her hand trailed down his black t-shirt on his arm. She watched the silver piano key printed ring, he had given her last night, spin on her middle finger as her hand moved. She settled her hand on his forearm.
"So, tell me about this 'glue-sniffer' that Wendy is marrying tomorrow," Luke said.
Amy laughed as he had recalled how their mother described their cousin's fiancé. "Well, I told you about him before, but I'll refresh your memory. His name is Greg."
He nodded. "Okay, but what makes Mom refer to him that way?"
