Rebecca had been lying on her bed in the dark for what seemed like a good 10 minutes before she heard Mark’s footsteps on the stairs. She had shut off her laptop, and lit two candles on her nightstand. Beside them was a long strip of leather that she had pulled from her journal, a condom, and the panties she had been wearing.
She had put on a bit of Pearberry perfume. Her long t-shirt hid her body down to the middle of her thick, silky thighs. As she anticipated the glorious retribution she would exact on her step-brother in only a moment, she couldn’t help but reach down and begin to pleasure herself.
Just as she was getting going, she could hear Mark approaching. She got up and sat on the edge of the bed.
“Is she still asleep,” Rebecca asked as Mark came into the room. He had three thick, whippy pieces of tree branch in his right hand.
“Yes, she is. I checked,” he said softly as he closed the door behind him.
“Good, now hand me the switches.”
Mark did as he was told. Rebecca took each one and whipped it in the air. “These should work just fine,” she said matter of factly. Mark stood over her, unsure of what to do next.
“Well, don’t just stand there!” she said with irritation. “Get your shorts down and lay across my lap!”
“Yes, ma’am,” he said in a meek voice as he reached down to his shorts. He pulled them down to his ankles. “Underwear too?”
“It’s nothin’ I haven’t seen before. Get ’em down.”
Rebecca’s eyes were fixed on Mark as he exposed himself. She couldn’t help but smile at the look of humiliation on his face. She patted her right leg. He waddled over to her and laid across her lap, resting his placid manhood against her thigh.
“Put your hands behind your back,” she said.
Mark obeyed, and Rebecca took the strip of leather from the nightstand. She tied it tight around his wrists. She took her panties and bunched them up against his lips. “Open wide!” she commanded. And as he did she stuffed her underwear into his mouth. Finally, she placed her right leg over both of his, and took a firm grasp around his waist.
“You have been a very bad boy, Mark. You have earned yourself a good old-fashioned swicthin’. Now hold still!”
With that, she reached for a switch and whipped it across his bottom. He jerked, but the leather around his wrists made it easy for her to hold him in place. She whipped him again. His pale cheeks clenched as the branch cut across them. Then again, with the same reaction, this time coupled with a muffled moan.
“Does that hurt?” she asked.
Mark nodded.
“Good. Are you learning your lesson?”
He nodded again.
She resumed whipping, this time harder, and faster, causing her step-brother to squirm and whine at the same time. Her whipping became metronomic, the switch falling roughly every second. Mark’s writhing and quiet whimpers only made her switch him harder.
“You are such a naughty boy!” she whispered angrily as she brought the switch down. “You’re damn lucky you have me, you know that? How many girls you think would do this for their sibling? Not many…”
The switch continued to rain down.
She stopped for a moment. She could tell that his bottom was already covered in thin red welts. She ran her fingers across them. She heard him sniffle.
“Are you ok Mark?” she asked.
He nodded and looked back at her, but sure enough, there were tears in his eyes.
“Are you regretting our arrangement?”
He shook his head no.
“But you’re regretting your behavior, aren’t you?”
Suddenly he went from teary-eyed to sobbing. Rebecca rubbed his back gently, and soothed him. “There, there…it’s ok. I’m only doing this because I love you. You know that right?”
He nodded, and rested his head on the comforter. His tears subsided, and Rebecca picked up the switch once more. “Mark you got 25 more comin’. You take ’em good, and you’ll be all done. If not, then you get ten extra, understood?”
He mumbled unintelligibly through the panties in his mouth. She removed them, and held them in her hand. “I’m sorry what was that? I want to make sure I can hear you clearly.”
“Yes, ma’am,” he repeated. “I’ll be good, I promise.”
“Good boy,” she said stuffing her panties back into his mouth. The scourge of the switch returned, and Mark was now kicking his legs, his muffled cries becoming louder than before.
Rebecca loved watching the way he squirmed in her naked lap; the way the switch made that whippy little sound before it struck his cute, tender bottom; the way his bound wrists, and panty-stuffed mouth ensured her complete dominance over him. It seemed each whip of the switch was making her wetter.
It wasn’t just about the power that she had, or the sight of his naughty bottom under her cruel hand. It was that all her life she had been the quintessential girl next door. Her mother’s strictness notwithstanding, she had done everything she could to be the model daughter, student, member of her church and community. But every good girl has a naughty side. And Rebecca was discovering hers for the very first time. It drove her wild with excitement and desire.
Finally, she thought it was time to bring Mark’s punishment to an end. And so she held him as tight as she could, and lifted the switch high into the air. She brought it down with all her strength in a grande finale of ten good whips, Mark was no longer kicking or squirming. He had resigned himself to his whipping, realizing full well that is was long deserved, as was his step-sister’s enjoyment in carrying it out. Nonetheless, he was sobbing once again.
“All done sweetie,” said Rebecca tenderly as she placed the switches on the nightstand. She released his legs, and untied his hands. She guided him back to his seat on the bed as he wiped his tears and sniffled.
His dick was swollen though not erect. She reached for it. “Oh my…your johnson is a little bigger than it was when you first went over my lap. And is this what I think it is?”
She stooped down and placed her mouth on the tip of his dick which was glistening in the candlelight. She sucked off the moisture, tasting it’s saltiness. He grew larger, and in just a few seconds found himself with a monster of an erection. She looked up at him and puckered her lips off the head of his manhood. “You’re coming a little,” she teased him with a smile. “Did you like that? Do you like getting your bottom whipped by your step-sister?”
Mark nodded as his breathing grew heavier. “I…I think so,” he panted. His head then went reflexively back to the headboard as he inhaled sharply. Rebecca was now sucking him off in earnest. Her lips were sucked firmly around his shaft, bobbing up and down slowly. Mark brushed her hair from her face, and watched in bewildered delight while his most forbidden fantasy came to life before his very eyes. Within seconds he found himself on the verge of climax.
“Ohhh Becca, you have to stop!!”
She immediately pulled away, startled. “What is it? Was I doing it wrong??” she whispered frantically.
“No, no no…you were doing amazing,” he said under his labored breath. “I was going to come, and I didn’t want to shoot my load just yet.”
“Ohhh I see,” she said sounding relieved. “I was worried. I’ve actually never done that before.”
“Never? Really?”
“No, never. I mean, I’ve been watching plenty of how to videos, and I practice sometimes on my toys, but never with a…well, a real man.” Her smile took on a shy, vulnerable character.
“Are you a virgin?” he asked with a curious smile.
Rebecca nodded. The two stared at each other in silence smiling in anticipation of what the other might do next. Finally she bit her lip and raised her eyebrows.
“Buuut…maybe, not for much longer??”
Mark had gotten lost in her innocent eyes which were slowly getting closer to his. Then, in a burst of passion he grabbed her forcefully, and in one swoop put her on her back. He kicked off his shoes and shorts. Rebecca hastily pulled her t-shirt over her head. Her eyes were wide and transfixed on the first naked man she had ever seen, had ever touched, or had opened herself up to so vulnerably. Mark was staring at her naked body worshipfully.
Mark stooped to kiss her lips. His hand meandered down her torso until her was gently rubbing the small shaven hair patch between her legs. Rebecca moaned and reached for his balls. She fondled them, and opened her mouth to receive his tongue.
Soon Mark moved his lips to her neck. Then to her breasts. He entered her with his fingers and sucked her nipples one at a time until she seemed utterly lost in erotic bliss.
She grabbed onto his head, and pulled on his hair. Mark moaned but did not remove himself. Then he felt a sudden pressure. She was pushing him downward. He obeyed, and began smooching her tummy. She pushed more, and Mark descended along her body until his mouth was only inches from her sex. He grabbed her thighs, spread them, and began a thorough exploration of his step-sister’s womanhood, making liberal use of his warm slippery tongue.
Rebecca’s mouth dropped, and opened wide. She desperately tried not to scream, but soon had no choice but to cover her face with the pillow beside her. Mark could hear her shrieks, muffled, but intense. It only made him lick, and suck with even more veracity. Never before had he given so much effort to please a woman. Never before had he wanted to. But Rebecca seemed to arouse in him a deep desire to satisfy, even at the delay of his own pleasure.
As Mark continued, Rebecca removed the pillow and frantically reached beside her while she squirmed. Finally, she found what she was groping for, and picked up the switch from the nightstand. She held his head and lifted her torso just enough to get a good shot at his welted bottom.
Panting, she cracked the branch down on his butt again and again letting each whip drive her deeper into her ecstatic state. Mark started to squirm himself which only brought her closer to climax. She increased the force of her strokes until finally, she was whipping him with all she had. As she did she could feel the tender hyde of her own bottom rubbing against the comforter, reminding her of the very sensation that was hers only ours earlier. Mark took it all as pleasure, and ate her like the fate of the world depended on it.
Soon Mark’s mouth was dripping with her juices, as well as his own, and he could feel her hips shudder up against him. The switch had dropped to the floor, and the pillow was again over her face. Her legs were wrapped tightly around him as she writhed from left to right again and again. His face remained buried between her luscious thighs until finally, her orgasm began to subside. He withdrew, and caught his breath.
After catching her own Rebecca sat up and touched her palm against his cheek. “Thank you! That was…you are…you did such a good job!” she whispered.
“You’re welcome sis'” he said as bent down to kiss her. “Does that mean I get the honor of taking your virginity now?”
Rebecca laughed and rolled her eyes. “Yes, you do. Just don’t call me that!”
“What would you like me to call you?”
“Call me…sweetie. Like you did before.”
Mark took the condom from the nightstand, and began to roll in onto his dick which hadn’t lost an inch of its stiffness. “Ok sweetie,” he said. “Spread your legs for me.”
“Why,” she said smiling, and covering her pussy with her hands. “What are you going to do to me?”
He bent down and whispered to her, “I’m going to put my hard cock in your pussy sweetie. Then I’m going to make love to you until I come inside you.”
She reached for his dick, and began guiding it toward her. “I like the sound of that,” she replied.
And with that he entered her, feeling for the first time the warm tender fruit that had for years been the subject of his wettest dreams. He thrusted hungrily, panting and whispering her name beneath his breath. Rebecca’s response was much the same. She grabbed onto his welted moon with both hands, and pulled him into her with each gyration of their hips as they moved in tandem.
They moved like that for hours, at times lost in passionate lovemaking. At other times they fucked playfully, trying out different positions, and locations throughout the room. They both learned how wonderful sex on the floor could be since it allowed them to thrust on each other more vigorously without making noise.
At one point they decided to throw the mattress on the floor and go at it in every position they could imagine. Mark would fill three condoms with his load before the night was over. Rebecca had two more orgasms herself, and was in the throes of her very last when she saw the sun come up through her window.
Finally, the two lay on the mattress in a loving embrace while Mark stroked her hair and she played with his balls. “The sun’s up,” she said in a sleepy mumble.
“That means your mom must have left for work already.”
“Oh, yah, that’s true,” she mumbled. “Will you set an alarm for noon?”
Mark reached over to his phone and did as she asked. “Sure thing. Is that when you want to get up?”
“Yah…” she said as she began to drift out of consciousness.
“Um…I’m just curious, but…if you’re a virgin, then why do you have condoms?”
“I like to plan ahead. I had a strange feeling you might be my first. I’m glad you were.”
“I love you Becca,” he said as he kissed her forehead.
“I love you too baby.”
And with that, the two of them drifted off to blissful, sunlit sleep.
