“Wow, you’re way naughtier than I ever imagined, kiddo,” he leaned down to kiss her again as they ground together.
“Always been like this… you just never noticed,” she ducked his kiss to suck on his chin then nip at it gently.
He groaned and did exactly what she wanted – he fucked her harder. He drove her slender body down into the mattress beneath them, bottoming out inside her at the end of each stroke. It send pleasure-pain tingles through her hips.
She moaned and cooed in response to the more energetic screwing. Her arms flew around his back and she clawed at his skin.
They were fucking now, really and truly fucking in the way they’d both secretly fantasized about over the years. It was wonderful. It was magical. It was everything they’d furtively conjured in their twisted little minds. Of course, it’s also when they heard a knock at the front door of the house.
“Liiizzzziiie? Riiiiichiiie?”
They both froze, eyes flying wide open.
Their mother’s voice! What the hell was she doing there already?!
Their mother unwittingly answered their question, “I took off a couple of days from work and drove down early. Thought I’d surprise you.”
Surprise was right! Thank god the front door was locked, but then Richard pictured the door at the house’s rear. It was open and they were on ground level. If their Mom came around…
He did the only thing he could think of. Still joined at their middle, he picked his sister up off the bed and carried her into the bathroom and shut the door. He plunked her down on the bathroom counter.
Moments after the bathroom door shut, from inside the house now – “Rii-iiich? Lizzie?” She’d found the open door.
If their mother caught them they were dead. No doubt about it. He started quietly reciting the Lord’s Prayer with his erection buried deep inside his own sister. He knew he’d be explaining that to Saint Peter someday.
Richard might be the family brains but Lizzie, bless her, had always better under pressure. She smirked and snaked her arm out, then pushed the little button on the knob of the bathroom door to lock it.
“I’m in here, Mom,” she said loudly. “Just having some trouble with breakfast. Too much pineapple, I think.”
“You’re not throwing up are you? Is it morning sickness? Are you pregnant?”
His sister rolled her eyes at him. “Why is that everybody’s first thought?” she whispered.
He shrugged, keeping quiet.
“No, Mom. I’m not pregnant.” Then Lizzie’s eyes took on an evil gleam. “At least… not yet anyway.”
His sister humped against him, driving herself further onto his cock. Somehow, despite his complete terror, he was still hard. He didn’t move as Lizzie humped up again and ground herself against him smoothly.
“You sure you’re all right, Lizzie? You sound funny.”
“Uh huh… I’m good.” Her lips pursed appreciatively as she carefully pumped herself fully on his shaft. Oh god, his sister was enjoying this.
“In fact, I think I’m feeling better already, Mom.”
“Good. Good. Where’s Richie, honey?”
“Oh, he’s around here somewhere.”
“Down at the beach?”
“Maybe.” Lizzie answered dully, losing focus as she silently fucked herself on him and her pleasure mounted. She hadn’t cum yet and she needed to get off desperately. Her little tongue slipped out to the corner of her mouth in concentration and the adorable sight made Richard groan softly.
“His bathing suit is right here on the floor, though.”
“Uh, he’s got more than one, Mom. He’s not running around naked, I promise.” Lizzie rolled her eyes and kept using her brother’s cock hungrily.
“I certainly hope not.”
Richard was going out of his mind. Jesus, this was insane. His sister was fucking him a dozen feet from our mother with less than two inches of pine door between them. There was more adrenaline in his bloodstream than water at this point. His fear and arousal twisted and piled on top of each other. He couldn’t hold out against it for long. He looked down at his sister.
Liz knew the signs by now.
“Don’t you dare,” she threatened softly, glaring up at him.
“Cum inside you? Not on the pill?” he whispered back.
“No, I mean cum before me. Of course, I’m on the pill.”
Their mother interrupted from outside. “You still okay, Lizzie? Were you talking to me?”
“Yeah, I’m okay.” his sister called back. “I was just… uh… just… practicing my wedding vows.”
Richard’s mouth fell open in amazement at his sister’s outrageous answer.
She grinned up at him but her own depravity got the best of her. She couldn’t hold it together and she burst into giggles. The laughing fit made her stop screwing herself up into him.
“You’re wicked,” he gasped quietly, taking over and thrusting gently in and out of her drooling, overheated little pussy.
“Marriage isn’t funny honey. I hope you’re taking this seriously.”
“Sorry, Mom. I am,” his sister sighed. She nibbled her lip for a moment and did some first rate thinking under the circumstances.
“Hey Mom? You know, there’s a whole bunch of stores down in town that are having some kind of sidewalk sale today. There’s tons of pretty sarongs and stuff. Why don’t you walk around down there for awhile while I get sorted out?”
“Well, I could use some more beach clothes. Sure you’re going to be okay?”
“Yeah,” Lizzie answer came as a moan as her brother pushed her legs up and hooked them over his shoulders. From this angle, he could just brush the bottom of his sister’s vagina again and from her eager nods he could tell it’s what she needed.
“Okay, I’ll be back in time for lunch. Hope you feel better.”
“Already… feeling… better,” Liz cooed as her brother sank fully inside her over and over. “Have fun, Mom.”
They continued quietly humping for another minute.
“Okay, she’s long gone now,” his sister looked up at him, “quit messing around. I need you to fuck me like you mean it. You’ve been cautious in my ass and I appreciate it but this is not my ass. I’ve missed having a guy just go crazy on top of me. Do it. Take me. Please.”
He bore down on her again and she groaned gratefully as he pistoned his full length in and out of her sucking wet depths.
“That’s it Scooter… uh huh… fuck your wicked… little sister. Ugh.”
“Sis…?” his telltale warning came again.
“Don’t you dare…”
“Brothers … come first,” he gasped apologetically.
“Not… what that means… bastard,” she complained as she quickly slid a hand down to her clit and started rubbing herself, racing to cum before he gave out.
He won again. He didn’t mean to. He tried to hold out. But being in his sister’s pussy for the first time and barely avoiding getting caught doing it and just looking down at her tiny tight young body twisting and wiggling beneath him – it was all too much.
He came. Fortunately, Lizzie was right behind him. He felt her insides squeezing him rhythmically and it was almost impossible but he managed to jerk himself out of her to let his cum jet up onto her belly and breasts. Ropes of thick, white semen crisscrossed her body by the time he was finished.
“Shower?” he looked down at her, still gasping.
“Definitely,” she snickered, admiring the sticky mess he’d made of her.
They stepped in and shampooed and soaped each other sloppily, laughing as they coated each other in lather. The giggling came to an abrupt stop when Lizzie turned her back to him and bent herself over at the waist.
“Up for more booty practice?” Lizzie looked back at him hopefully, “Believe it or not, I’m still a little frisky.”
“Hmmm… I think I need to recharge. My last orgasm was a doozy. But, if you want, I could…”
“You could what?” Her eyebrows knit together in a cute way.
He spun her to face him again and pressed her slender body back against the tile. He slid down to his knees in front of her and kissed her at her stomach. He marveled at the large, keyhole space between her slender thighs before nuzzling her smoothly shaven mound. He’d been thinking about getting his mouth on her since she’d pointed out her hairlessness while standing in the kitchen in her underwear.
“Really?” she smiled down at him.
“Sure, why not? We’ve done just about everything else.”
“Okay, I will take you up on this. Since you’re offering.” She shifted and spread her legs then laced her fingers through his hair and pulled him to her.
He gently, tenderly ate his sister there in the shower as the water streamed down on them. She was right. She was frisky again. Her little button was swollen and hard already. He teased her a little, exploring the silky softness of her folds with his tongue. She was sweet and tart and musky all at the same time.
He settled into a steady licking at her pebble-like clitoris and she whimpered and pulled her brother into herself urgently. He stroked her long sleek thighs as he lapped at her baby soft slit. Minutes later, her orgasm wracked her body. She dug her fingernails into his shoulder and moaned his name over and over, “Scooter, Scooter, Scooter.” Each time she said it, the pitch of her voice rose until it cracked and she squealed softly, breath hissing through her little lips.
When she’d finished and started breathing again, he rested his cheek against one of her thighs, letting her shake out her final twitches of satisfaction.
“You know,” she looked down at him finally, “if I had any idea you were so good at that, I would have climbed up onto your face in the middle of the night years ago.”
“Bummer huh?” he smirked up at her.
They were watching TV by the time their mother came back. They had lunch together and it was back to being a regular family again. Richard was uncharacteristically quiet but Lizzie seemed to slip back into her old role easily.
It was harder for him. He kept glancing at his sister. She was dressed innocently in shorts and a t-shirt but she was still beautiful. Still sexy. He wanted her in a way a brother just shouldn’t. This was going to be difficult.
Lizzie seemed to sense his discomfort. She distracted their mother with hours of girl talk and he was grateful.
By the time they’d eaten their dinner, played a few rounds of cards and said their goodnights, Richard was practically sulking. He flopped onto his bed and laid there, listening to the waves outside.
He tried to get his sister’s beautiful naked body out of his head. She was getting married soon. This thing, whatever it was, that they’d shared was over. One last big experiment for Lizzie. A final fling.
*~*~* Part IX *~*~*
He didn’t remember falling asleep. He only realized that he was asleep when he woke up. It was the middle of the night and a familiar finger was tracing along his back in the dark. It shook nervously.
“Imu. Not getting married.”
His stomach rolled and his heart soared. “What?” he rolled over to look up at the faint outline of his sister in the thin light.
“Shhhh… c’mon let’s go down to the beach. We need to talk and I don’t want to wake Mom up.”
He felt her weight disappear from the mattress.
