Chapter 1: The Arrival
Lucy Thompson stood tall in front of the mirror, looking at herself for what seemed like the millionth time since she turned forty-six years old. She was not the woman she once was. Some of her Friends would refer to her as a MILF but she couldn't see it. All she saw was a face that was starting to age and wrinkle, breasts that were starting to sag and an ass had almost doubled in size and now to top it all off her 19-year-old brother was moving in.
This wasn’t how she pictured her retirement going – babysitting a teenager. Even if he was family, even if he could cook up a storm and clean the kitchen faster than anyone else, seeing him around made her feel outdated.
"What do you think?" Lucy asked, glancing over her shoulder and seeing her reflection. "Not bad," he said, smiling mischievously. Her heart began racing, partly because she knew where his gaze lingered most often during their conversation.
Their dynamic changed dramatically when his presence became constant.
Every morning Lucy woke up early just so she wouldn't catch him emerging from the shower, steam still rising behind him. It was hard not to be drawn to the bulge hiding beneath those tiny bathrobes. Each day, another part of her grew weaker. But, somehow, none of these feelings felt wrong. She understood why people called men in their late teens, early adulthood 'young blood'. It gave them energy, vitality. Simon was no exception, he had boundless energy which radiated throughout the entire house.
From taking care of household chores to creating delicious meals in a matter of minutes, he did it all effortlessly. Lucy found herself getting lost in admiration whenever she watched him move. Not only was his body toned from hours spent playing sports, but there was also an undeniable magnetism in his smile. If she didn't know any better, she might consider developing romantic feelings towards him, but alas, they shared a different kind of connection.
In fact, as the days went by, it started feeling less like siblings sharing a roof and more like lovers yearning for each other's touch. And then came the night. After months of suppressing these impulses, she finally took matters into her own hands. With her kids all in bed and her husband away again on one of his work trips, Lucy, Under the guise of checking whether he needed anything before bedtime, knocked gently on his door. “Come in” Simon said from inside his room. With trembling fingers, she opened the door to find him lying comfortably on his bed, reading a book with a small lamp beside him casting a warm light onto his features. Despite the situation she found herself in, she couldn't help but notice how handsome he was and how big that bulge was in his pants .
He looked up, startled briefly but recognizing her immediately smiled sheepishly. “Hi sis,” he said, putting down the book and sitting up on the edge of the mattress. There was a certain vulnerability in his expression that unnerved her slightly.
Feeling emboldened by their recent closeness, she approached slowly and sat beside him on the bed. Brushing against his arm, she tried desperately to gather her courage.
They were too far gone now; it was clear that they desired each other beyond words. Taking a deep breath, she leaned forward and kissed him softly on the lips. In response, he wrapped his arms around her waist and pulled her closer. The sensation sent shivers through her body as they continued exploring each other's mouths with gentle passion. Their bodies pressed against each other tightly, and Lucy felt her nipples brush against his cotton shirt.
Desire raged through her veins, making her dizzy with want. They moved closer until there was nothing separating them except thin layers of fabric. Growing bold, Lucy reached down and unbuttoned his jeans, reached underneath his boxers and her hand meeting the the biggest cock she had ever felt. It was only as she pulled it from his boxers that it’s size was truly revealed - a long thick and veiny shaft probably 11 or 12 inches long, two shaved plum sized balls and large helmet shaped head. It was the most perfect penis Lucy had ever seen.
As Simon felt her grasp firm around him, a wave of pleasure coursed through his system and desire surged deeper, causing his groin to twitch involuntarily.
Without breaking eye contact, Lucy lowered her head and ran her tongue along the base of his shaft, drawing a moan from his throat. Encouraged by his reaction, Lucy increased the pressure and speed of her strokes, applying occasional flicks of her tongue against the tip of his cock
“Does this feel ok Simon?, I’m afraid i’m a little out of practice” Lucy asked
hesitantly.
"It feels incredible", he replied breathily, his hips beginning to rock subtly with her movements. His erection swelled further in her grip, seemingly growing bigger with each passing moment.
Her confidence boosted, Lucy decided to push things a bit further. Grabbing his hand, she led him across the room to the dresser. Standing with his back to it, she positioned herself strategically behind him. She carefully removed her clothes and threw them haphazardly aside.
Naked, she returned to stand behind Simon, wrapping her arms around his waist while pressing her nude form against his back. "Are you sure this is what you want, Simon?" she whispered nervously, her hand finding itself resting on his rigid member once more. Simon nodded fervently, unable to contain his excitement any longer. "Yes, yes!" he cried, turning around to meet her gaze with fire in his eyes.
Without hesitation, Lucy guided Simon towards the nearby bed, laying him down upon it.
Her deft hands caressed his chest, eliciting gasps from him. Moving downwards, she cupped his erect member, marveling at its enormity once more. With a practiced thumb and index finger motion, she began rhythmically stroking the sensitive skin beneath his shaft. This action alone drove him wild; he let out a low growl of approval and urgency. Feeling emboldened, Lucy slid her hand up and down his length, occasionally teasing the ridge of his head.
Simultaneously, she dipped her head to take him into her mouth, effectively maneuvering her lips and tongue around his massive shaft. Unable to control himself any longer, Simon grabbed hold of her hair, pulling her closer. His thrusts quickened, nearly pushing her off balance. Lucy used one hand to steady herself against the wall while continuing to service him with determination.
Meanwhile, Lucy's body ached for relief. Reaching behind her, she palmed her breast, pinching her nipple between her fingers.
With a slight jerk of her head, she directed Simon to suckle on her breast, watching as his mouth closed greedily around the soft flesh. Aroused by the taste and sight of her succulent bosom, Simon devoured her breasts hungrily, alternating between them, leaving red marks everywhere his teeth grazed.
Thrilled by his attentiveness, Lucy responded in kind, letting her fingers roam freely through his bushy pubic area, stopping to tweak his hardened nipples playfully.
She then eased herself onto her knees, bringing his engorged organ level with her mouth. Her lips closed around the broad head, savoring the texture of his velvety skin.
"Oh fuck," Simon uttered, stunned by the intensity of her first taste. His hips bucked involuntarily, seeking relief from the burning pressure building within him. Yet he held back, wanting to prolong their encounter. His self-control seemed to empower Lucy, encouraging her to deepen her sucking technique, increasing the intensity of stimulation flowing through his body.
Desperate for release, Simon buried his face in Lucy's neck, trying to regulate his heavy breathing.
Lucy could sense his struggle, knowing exactly what would alleviate some of his discomfort. With a wicked grin, she released his shaft from her mouth, trailed wet kisses from his pelvis, to his abdomen and then up to his chest and then reaching her hand back down to the top of his thick shaft. Lucy continued kissing upwards until she reached his mouth and began kissing him deeply. She brought her right hand into play once more, and began stroking his huge cock with both hands.
Each stroke resulted in a visible increase in arousal as he leaked precum all over Lucy’s ripe breasts. "Fuck! That feels so good." Simon exclaimed, bracing himself against the wall. His head fell backward, exposing his throat. His mature sister started lovingly kissing and nuzzling his neck while simultaneously removing her remaining clothes.
She wanted to enjoy this experience fully, taking advantage of their taboo relationship. Without much pretense, she bent down and again enveloped his enormous cock with her warm, welcoming mouth. Using all her skills, she sucked, licked, and blew hot air down the shaft, sending waves of pleasure crashing through Simon's body. His heart raced frantically, his blood pumping fast. He knew if he didn't cum soon, he wouldn't be able to stop.
Raising his voice, he stammered, "Please stop Lucy or I am going to blow the biggest load ever straight into your mouth”
“and what we be so bad about that?” asked Lucy in between sucks. I so want to fuck you and I’m pretty sure you want to fuck me to." Lucy without question, rolled over onto her hands and knees and said “ what are you waiting for, fuck me already little brother , I want you take that pussy splitter of yours and fuck me like I have never been fucked” she stated almost calmly. Simon almost could believe what he was hearing, positioned himself behind her, aligning his erection with her entrance. Slowly, he pushed himself into her, reveling in the feeling of his enormous tool filling her completely.
Lucy gasped audibly, feeling pain mixed with pleasure at the intrusion. Clutching the sheets, she bore down and accepted his bulk within her.
Each powerful thrust sent a shockwave throughout her body. "That's it…that's it…so fucking good," she muttered breathlessly, as his entire length was now inside her. As he picked up the the pace, Lucy felt her first orgasm of the night roll through her like a tidal wave. She arched her back, offering her big breasts to him. He grabbed both breasts from behind and continued to pound his sister with long strokes.
As Simon grew nearer to orgasm, he began to pick up the pace.
Lucy couldn't help but watch her brother pound into her through his bedside mirror, his movement, intensifying their connection. Breaking their embrace, Simon turned her over as Lucy spread her leg’s invitingly, giving Simon a perfect view of her hairy pussy with just her bikini line trimmed. Lucy reached forward a grabbed his bib cock again and rubbed his head all over her pussy lips before she forced him back inside her. As he agin stated fucking her with those long strokes she loved, Lucy wrapped her legs around his torso. The sensation of his enormous appendage stretching her internal passage to new limits made her giddy with anticipation. Every part of her craved satisfaction. And now, finally, she would get just that.
Their sex became fierce and demanding, fueled by the forbidden nature of their relationship.
Lucy no longer saw Simon as her younger brother, instead seeing only the object of her desires. It was clear Simon had developed similar feelings towards his older sister.
Feeling a primal need to dominate her younger brother, Lucy took charge, instructing Simon to switch positions. He readily complied, lying on his back, he allowed Lucy to mount him. She placed her hands on his chest as she expertly moved her hips in time with his upward thrusts, creating a mesmerising dance of bodies. Meanwhile, Simon tightened his grip on her hips, driving himself deeper into her.
Each thrust sent waves of ecstasy coursing through Lucy's veins. She moaned loudly, lost in the euphoria of their intertwined limbs and entangled passion.
As Simon approached his peak, Lucy slowed their tempo slightly, wanting to draw out the anticipated climax. He groaned, his muscles tensing with each powerful thrust. In response, Lucy pressed herself harder against him, meeting each forceful strike with equal strength.
Just as she thought she couldn't bear another second of this unrelenting desire, Simon found his release.
With a hoarse cry, he shot his seed into Lucy's fertile belly, where it spurted forth in long streams. Simon pumped rope after rope of his cum into his sister as she pulled him closer, milking every drop. With his cock now softening inside her she reached down and kissed her brother deeply, “Thank you Simon” she whispered, then kissed him deeply. As she got up, Simons cock made a beautiful popping sound as it left her well satisfied pussy and collected her clothes and went back to her room where she slept deeply for the first time in months.
