Accepting Desire

"We have a little bit. Here, lay down, you've been on top for a while."

Now it was Mariah's turn to be in control. She kissed his neck, trailed down his broad chest and abs before biting his hips, running her tongue along his v cut, and then her lips found the tip of his cock. Paul moaned as her lips engulfed the head while her hands worked it further down. With every downstroke, she took a bit more, and soon she felt him pressing at her throat. She pushed past that and took him deeper, seven inches now. Then Paul began thrusting, he couldn't help it. His hands took her by the hair, and all ten inches plunged into Mariah. She loved it and grabbed his butt, pulling him into her mouth as he began fuck her throat in earnest. Soon, she felt him swell slightly, and he buried his cock in her, holding her in place as he pumped and pumped and shuddered but it kept coming. Mariah couldn't help but wonder if she could eat breakfast after this. Paul relaxed his hands, and Mariah raised herself, sucking all along the way to get out every last drop.

"Oh my god," Paul moaned. His deflating, glistening, and still surprisingly impressive dick was flopped over one leg while Mariah eyed it hungrily. "That was amazing. You are too good at that."

Mariah gave him a sultry smile, "You can return the favor tonight." Then she turned around to get dressed, wiggling her ass seductively.

It was Monday, and it turned out that Robert and Michelle still had to work a half week before they got off for the holidays. At first, Paul and Mariah shared a naughty, promise laden look. But their parents left a chore list, told them to spend some time with Grandpa, and Paul and Mariah had already made plans to see their respective friends. They did not have time to fool around. After Robert and Michelle left, the siblings made breakfast for them and Grandpa, and then sat down with the chore list, which was entirely cleaning. Grandpa went back to his room and watched TV, unintentionally giving Paul and Mariah some privacy. And they took advantage. Mariah would be cleaning and suddenly find herself pinned against a wall, her breasts and nipples pinched, bit, and generally teased. Paul would suddenly feel a hand slipping along the front his basketball shorts, breasts pushing into his back, and then the hand would dive inside, wrapping around his cock and making him moan. He had an erection almost all day, and once had to quickly sit down as Grandpa wondered in for some lunch.

When they were done, Paul and Mariah went to have their separate fun. Paul rock climbed with two buddies, staying sober and having a blast. Mariah went to a friend's party, drank too much, got hit on a lot, and left late. She had one of her friends drive her home, and then she wondered into her room. Paul was already in bed, and Mariah eyed him hungrily. She stripped naked, still staring at him, and bit her lip while touching herself slightly as she imagined him taking her. Her hands pinned down, his mouth ravishing her neck, breasts, belly, lips, and then his cock plunging into her. Mariah quickly crawled into bed. It was cold, so she scooched up to Paul for warmth, ending up playing the big spoon. Mariah wanted to be fucked, but needed to warm up first and foremost so she lay her head down...and fell asleep.

Paul wasn't sure how best to wake Mariah up. After he'd said goodbye to his parents and made Grandpa breakfast, he said he was still tired and going to get some more sleep. And so here he was, eyeing his little sister knocked out cold. I was time to pay her back for the blowjob, he decided. He got naked and crawled under the covers head first. He fumbled slightly, but then his lips found hers and he kissed gently, working his tongue into her outer folds. His arms held her hips and he slowly kissed her pussy till Mariah woke up gasping and moaning. Still half asleep, she unconsciously ground into his face and pinched her nipples. Paul picked up the pace – waking Mariah more fully – and then payed special attention to her clit as he slid a finger up inside of her.

"Ooooh, Paul! Yeeeeess! Right – OH! – There – OH! – Oh, Gooooddd!" Mariah clung to the note and Paul's hair as he pushed a second finger inside and started rubbing her G-Spot. "Yes! Yes, yesyesyesyes – OH! I'm gonna cum. Keep...right – OH! Oooohhh!" She stuffed a pillow over her face and screamed as she came, gushing fluid and clamping down on Paul's fingers.

She was still quivering as he pulled them out and lined himself up with her entrance. Mariah left her eyes closed, but took the pillow off her face and breathed deeply, her chest heaving and showing off her breasts. Paul pushed in slightly, and lay his chest on hers so he could kiss her while gently rocking in and out with just the tip. Then he bit her neck, ran his tongue over her clavicle, bit her nipples, and left her moaning, "God Paul, just...just fuck me already. I can feel that huge dick of yours teasing me, I can – OH! –" she cut off as Paul plunged in another inch. Then he steadily worked his way deeper, pushing further with every thrust as Mariah learned to moan the mantra, "Oh god, oh god, so deeeep!"

When Paul's hips met Mariah's, he held himself fully inside for a moment, and began fucking her with slow deep thrusts. "Fuck!" She chanted with each thrust, "Fuck, fuck, OH! God YEEESSS!" Paul's teeth worked her nipples, her throat, his hands pinned hers, and he kept pressing inside, filling her up. Mariah was overwhelmed with pleasure, each wave building inside, each thrust felt like the oncoming freight train of her orgasm. Back arching, fingers clawing his back, Mariah exploded. She quivered, gasped, her eyes closed as all sensation was muted by pleasure like sweat bleeding out her pores. Paul sat up on his heels, hooked his elbows under her knees and started fucking her with longer thrusts, pulling her hips into his and building the pace. Mariah screamed into a pillow, her still sensitive pussy overwhelmed and loving it, while Paul was consumed with the building, churning pleasure. Each thrust impaled Mariah ten inches deep, and she was soon cuming again, her hands gripping the bedsheets as she clamped down on Paul. He buried himself inside and swelled before bursting, his essence pouring into his sister. He pressed their hips together as he felt himself pump and pump. Mariah came off of Cloud 9 to the deep thrum hum pleasure of being stuffed and filled up, and she felt herself milking Paul's member as he slumped on top of her. Mariah smiled with that just fucked radiance that makes the world seem enchanted and knew this was going to be a good Christmas break.
