Chapter Text
Friday 7:36 pm
Tom gripped the door hard, fingers pressing so hard it hurt the bones, but his other hand lifted and gave a gentle wave to his mother. She turned and blew him a kiss from the car window and he gave her one of his polite smiles, the ones that had just about everyone eating out of his hand. Everyone, but not his step-father—he was giving Tom a dark look, a reminder of the talk they’d had after he and Tom’s mother announced they were going out of town for the weekend.
“Take care of my little girl.”
Yeah. He planned to do just that.
Tom left the smile plastered on his face until his step-father got into the car and pulled out of the driveway.
“Bye, honey! Love you!” his mother shouted from the open window before they turned the corner and disappeared from view.
Tom closed the door. His fingers graced over the metal knob of the lock, a strange excitement shooting to their tips before he swiftly turned it and the bolt slid into place with a deep thud.
He didn’t second guess himself or waste any time. He had waited for an opportunity and this one had fallen into his lap. It wouldn’t be the only thing on his lap this weekend, Tom would make sure of that.
His bratty little step-sister had been a torment to him for years. Tom’s mother had married Hermione’s father when Tom was eighteen and Hermione sixteen. Their parents, thinking they were similar in age, expected them to get on swimmingly and Tom had done his best to be welcoming for his mother’s sake even though he had no desire for either a step-father and less for a step-sister.
It seemed the feeling was mutual. His step-father had never warmed up to him and always blamed Tom for anything that seemed to go wrong, from the milk not being put back to the party Hermione had thrown the last time they went out of town. That had solidified his opinion that Tom was a bad seed and the fact that Hermione stood there, acting innocent, made Tom hate her just as much as her stuck up father.
Tom had been happy, just him and his mum. They never had much money or lived anywhere near as nice as the house they had moved into once she remarried, but at least it had felt like a home. These people, Hermione and her father, weren’t his family and this wasn’t his home and Tom had been eager to move out when he earned a full ride to university.
Most of the time he stayed at school for holidays, claiming to need to use the time to study, but summers were different. Last year he had rented a room and spent almost everything he earned working just to pay the rent since he refused to take a dime of his step-father’s money, not that he had offered any. This year Tom swallowed his pride and came back home, hoping that if he saved enough, and worked part time once he went back to school, he wouldn’t ever have to come back to this house.
He returned to find not much had changed, his mother was still head over heels for her new husband who still regarded Tom as something dark and dangerous that shouldn’t be trusted, let alone, allowed inside the gated community he lived in. The only thing that had changed while Tom was away was Hermione.
In the last two years she had gone from a skinny little girl who read too much to…
Tom stopped outside her door. It was cracked and he could see her inside, lying on her bed. Big headphones dented in her curls and her ankles were crossed in the air, her body propped up on her elbows while she scrolled on her phone.
Tom let his excitement flood his blood, making it race quicker through his veins. Hermione rocked her feet in the air, giving him a quick peak of her ass as they bounced back and forth. Just a little of her plump cheeks were visible out of the bottom of her shorts and Tom swallowed hard, his ears ringing slightly as his cock twitched in his jeans.
When he got home from school she had been wearing those exact shorts, as if she had wanted that to be the first thing he saw her in since… since the last time they’d seen each other.
None of that mattered now. Now, all that mattered was it was him and Hermione, all alone, until Sunday evening.
And Tom wasn’t about to let this opportunity slip out of his fingers. In fact, he had a much better plan as to what to do with them this weekend.
Tom pushed Hermione’s bedroom door open, expecting her to turn around and look over her shoulder, but he made it to the edge of her bed and Hermione still had not acknowledged his existence. Typical. She had always thought she was better than him, the headphones currently sitting on her head cost more than Tom made in a month. He tilted his head, appraising the situation.
He’d have to get her attention another way.
Tom grabbed onto her crossed ankles with one hand and pulled her to the edge of the bed until she was bent over the side. Hermione yelped and tried to turn over, but Tom was quicker and pinned her down with a heavy hand on the small of her back while the other came down hard across her ass, smacking it hard enough to make her gasp sharply.
Hermione twisted her head over her shoulder. “Tom!” She pulled the headphones off, tossing them aside. “What the fuck do you think you’re doing?!”
Tom smirked, the expression sliding as easily onto his face as the fake smile for their clueless parents had moments ago. He knew how charming he looked smiling and how devastating his smirk was and the fact that Hermione paused in her struggle let him know it was in full effect.
“You know exactly what I’m doing,” Tom said calmly. His dark eyes darted down to the where the round crescent of her ass peaked out from the bottom of her shorts and felt his smirk spread as he watched the skin turning an angry red. A small noise and another jerk of her body had his gaze back up on her face. “I’m doing what you’ve been hoping I would ever since I came back, Hermione.”
Her eyes widened a fraction of an inch right before she started to twist and buck, trying to dislodge his hold on her. Tom smirk fell a little and swatted her ass again. This time he was able to watch it shake with the reverberations of his slap and Tom pulled his lower lip into his mouth, savoring the sight of it coupled with the cry tearing out of Hermione’s throat as she balled her comforter in her fists.
“Tom!” she wailed and he let out the breath he had been holding at the sound of his name passing through her lips.
“Hmm?” he hummed, seemingly unbothered by her discomfort.
Hermione was breathing heavily as she pushed herself up again, turning to look back at him. There were thick curls falling into her face and Tom was possessed with the urge to tuck them carefully behind her ear, but before he could make a move one way or the other, Tom saw the tears pooling in the corners of Hermione’s eyes and felt something swoop through his midsection.
It settled low in him, hardening his cock as he watched her face flush in a combination of anger and anxiety. He knew what that felt like, and what it really meant. She had made him feel it all summer.
“I’m going to let go now, Hermione,” Tom said in a mild voice. “If you try anything, I’ll spank you again and it will make the other two look like love taps.”
Hermione tensed as Tom let his fingertips trailed over her lower back, dipping into the dents right above her waist, but she didn’t move. Tom’s cheek twitched, pulling his lips up in a half smile. She stayed like that as he ran his hand over her hip, following the natural curve of her body until he reached the small inch of her ass that creased against her thigh.
As soon as he touched the reddened skin, Hermione jumped. She was halfway off the bed when Tom snaked his arms around her middle, pulling her back against him as they crashed onto the mattress together.
“Get— OFF!” Hermione shouted as she struggled against him, but Tom had planned for his and shoved his knee in between hers, constricting the movement of one of her legs and creating a gap between them. Leaning his weight down on her back, he reached up and fisted the hair on the back of her head and pulled hard.
She let out a loud cry, clawing at his hand in her hair and his arm around her middle. Tom relished the feel of her sharp nails in his skin.
“You want to fight me?” Tom asked, his lips pressed into her ear.
“I want to kill you,” Hermione snapped back at him.
Tom chuckled and thrust his hips forward, grinding them into her ass. “No you don’t, that’s not what you really want, now is it, Hermione?”
She stopped moving and Tom knew her heart was racing—just like his. Slowly, he started to slide the hand underneath her around the side of her body pausing at the waistband of her shorts. There he waited, feeling the goosebumps rising on her skin. Hermione let out a slow breath and leaned her head back slightly. Tom watched as her lids closed and her lips opened.
Curling the sides of his mouth triumphantly, Tom let his hand travel lower, skimming over the few inches of bare, soft skin before reaching the button on the top of her shorts. He popped it open and breathed in heavily, then quickly pulled his hand back and grabbed the cloth, pulling her shorts down to where her knees hung off the side of the bed.
Hermione let out a small gasp as Tom shoved his hand back in between her legs, but he stayed on top of her underwear. He watched the muscles in his wrist move, making the veins stand out as he rubbed his fingers over her cunt, feeling it soaking through the thin fabric keeping them apart.
“Is this what you wanted?” Tom asked. He was so close to her ear he could feel the heat of his breath billowing back against his face.
Hermione’s body heaved as she breathed in and out. “You’re insane.”
“Hmm,” Tom rubbed his fingers over her, feeling the small, swollen nub at the top of her cunt and tapped it with his middle finger, making Hermione gasp. “Must be a family trait.”
“Fuck you!”
Tom smirked and his tongue flicked happily inside his mouth. “If you insist, sister.”
He pulled back just far enough to get his hand inside her underwear before pulling it down and yanking her head back hard again.
Hermione cried out, but Tom merely pursed his lips, every muscle in his body tightening as he arched his arm, angling it over her ass to reach the soft, warm center of her.
“Fuck, Hermione, you’re so wet,” Tom practically groaned as he felt moisture flood around his fingers. He felt her thighs shake on either side of his hand as he slipped his fingers down to her entrance, sliding them in easily. He felt her tighten around the base of his fingers and opened his mouth, pressing his teeth into her neck without biting down.
“Tom!” Hermione shouted, but he ignored her protest.
Tom dragged his fingers out and thrust them back in, wanting to feel her cunt squeeze around them as he did it a second and third time, exhilarating in the feel of her whole body reacting to his intrusion. It might be wrong, but he wasn’t the only one who had been dreaming of this. It was easy to tell by the way her body started to rock with him that his little step-sister didn’t hate it as much as she was pretending to.
Tom’s blood rushed through his body, pounding in his heart and making him feel lightheaded as his cock swelled painfully. Tom focused on curling his fingers inside her, pressing in to make her arch her back and push her full, firm ass back against his cock. Hermione reached out, pulling on the blanket in an attempt to crawl away from him, but he had her trapped and corrected the offending movement by twisting his fistful of her hair and adding a third finger to her already tight cunt.
He felt her moisture leaking out and dripping down his fingers as he pumped them in and out of her. “Are you going to admit this is what you want now? Hmm?” Tom panted.
Hermione didn’t say anything, she just gave a deep moan, her arms splayed out on the bed, still grasping for purchase. If she wouldn’t say it, he would make her.
“I suppose I’ll just have to make you cum so you can’t deny it anymore.”
“Oh God…” Hermione’s legs shook as he pumped his fingers in and out of her at a punishing pace.
“He can’t help you now,” Tom murmured, trailing his nose along her neck. “Only I can. From now on, you pray to me.” She whimpered and Tom felt her cunt quivering around him. “Ask,” Tom licked his lips, “and you shall receive.”
Hermione twisted in his grip, her fingers digging into the soft comforter, but more to hold on than to pull away now.
Tom smirked. He had her.
“I…” Hermione breathed out.
He slowed just slightly and Hermione pressed her ass harder against his cock.
“I want…”
Tom grazed his teeth along the edge of her ear.
“I want…” When she trailed off, Tom pulled on her hair hard, causing her to cry out. He closed his eyes tightly, focusing just on the way her cunt fluttered around his fingers and how she was now grinding her hips along with the movement of his hand. “...I want to cum.”
Tom latched his lips onto the dip right behind her ear and sucked hard, flicking his tongue against the skin. He twisted his fingers inside her and pulled and pushed the thick bulge of his knuckles in and out of her tight cunt until she was shaking, crying, and gasping for breath as her orgasm took over.
He watched the way her eyelids fluttered, her lips puckered and opened, and stomach shook and quivered as she shivered, pleasure-drunk from the feel of his fingers. His cock leaked freely in his jeans and the only thing that kept him from coming was the thought that it would feel even better once he sunk his cock into her dripping cunt.
Hermione came down, tears mixing with moans as they dripped down her flushed cheeks and into her open mouth.
“Mmm,” Tom licked his lips again, tasting the salty tang of her sweat on them as he pulled his fingers from her tangled curls. “See? You wanted it as much as I did.”
Hermione slowly opened her eyes and turned to face him, a mix of awe and trepidation on her flushed face. “Oh God… I can’t believe I…”
Tom pulled his hand out from in between her legs. The evidence of the truth clear and coating his long fingers. He smirked before bringing them up to his lips and dragging his tongue along the length of his middle one.
“Oh God…”
“You should kneel to pray,” Tom commented as he licked the second one.
“What?!”
Traditionally, prayer is done on one’s knees.” Tom smirked. “Try it, and I’ll give you something to worship.”
She started her struggling again. “You sick—”
“You’re the one who just came all over your brother’s hand. If I’m sick, then you’re infected too.”
Hermione stopped fighting him, the full realization weighing down on her. She sucked in a large breath and expelled it in a loud sob.
“Shh, don’t cry,” Tom let go of her hair in order to pet her head softly. “I’ll make you feel good again.” He pulled open his jeans and the metallic sound of the zipper sent her into another fit of tears.
It was easier than he thought it would it be; Tom stroked his cock and squeezed the tip, letting a bead of moisture slide down the darkened head. Wiping it on the back of her thigh, Tom merely shifted himself so he was completely on top of her then simply slid inside.
He went slow, savoring every inch until he was buried in her cunt. The feel of it, the warmth holding him so tightly had Tom’s eyes rolling back and a low moan slipping from deep in his throat.
“Oh, Hermione,” he whispered as he positioned himself against her body, hauling her up the bed a few inches to get better traction before pulling his cock halfway out. “Your cunt is perfect.”
He thrust his hips and felt her walls constrict around him. Hermione screwed her eyes shut tight, gasping as he stretched and filled her. Tom felt lightheaded at the sensation and knowledge that he was fucking his step-sister. He let the feeling surge through him as he pushed himself harder into her.
Tom wrapped one forearm around the front of her neck, pressing on her throat as he angled himself to more easily move. He wrapped his other hand over the top of her head to hold her body in place underneath his as he began to quicken his pace.
“Tom…” Hermione whimpered pitifully, wincing when he gave a particularly sharp thrust.
“I know, I know…” He stroked her thick curls, lowering his lips to her ear again as he rocked his body back and forth quicker. “It hurts now, but it’ll feel so good in a moment, I promise, little sister.” He placed a chaste kiss to her hair and groaned as he heard her give a moaning cry.
Her cunt was tightening around him again and Tom had to focus not to cum when his balls started to tighten. He found himself beginning to sweat and pant as his heart beat faster, matching the faint fluttering of her walls.
“You’re doing so well, Hermione,” Tom murmured. “You’re taking my cock like you were made for it.”
“Please,” she moaned and Tom thick brows bunched together as his muscles strained against each other in a fight to fuck harder and hold back at the same time.
He closed his eyes for a moment, focusing on pushing Hermione over the edge of pleasure as he dragged his cock back and forth, pushing it deeper until he felt resistance as her cunt began to contract with the start of an orgasm. He tightened his hold on her, pressing his forearm hard into her throat and cutting off the desperate moans and only letting the soft gasps of air through. His fingers dug into her scalp as she writhed under him, unable to control her own body until the pleasure slowly subsided.
“There…” Tom said between heavy breaths. “Doesn’t that feel better?”
Hermione nodded softly, betrayed by her own desire and unable to deny what he had just caused in her body. Tom stopped himself from laughing and just smirked instead. Uncoiling his arm from around her neck, he grabbed onto her waist, shoving her down hard against the bed as he put more force behind his thrusts.
Hermione reached out, clawing at the pillows and comforter like a wild animal, which only drove Tom on more. A dark lock of hair fell in between his eyes and he let out a low breath as pressure built up inside of him, the need for release urged on by the tightening of her body around his cock.
He almost lost it when he felt her legs starting to shake again. Hermione was going to cum for a second time on his cock and a third time for him. Tom shoved her head down against the bed when she started to shake it, muttering “It’s too much… too much…”
“Shut up,” he said roughly and dug his fingers into her side, feeling the give of her skin under his strength.
Hermione was panting and moaning, her eyes only open enough for Tom to see the glazed look in them as she sucked in breath after breath into her mouth where her tongue lay against her bottom lip. Her body shook as her orgasm started again and Tom pumped himself harder into her, making it last even longer than her first one did.
She was so tight around him he felt his vision slipping out of focus, but he could still hear her gasps and groans which made the hair on the back of his neck stand up and a cold shiver run down his spine.
“Oh fuck!” Tom swore when he felt his cock harden even further right before he released a thick stream of cum inside her hot cunt. It sucked him in, walls waving as he rolled his hips and shot more, coating her quivering cunt. For a few seconds, he could do little else, but give sharp thrusts, streaming out everything he had until his balls ached, empty.
Slowly he regained control of himself and took a look down at Hermione who was loose and limp under him. Every now and then she would give a small moan and her cunt would seize up, milking him for every last drop. He had imagined what it would be like to fuck his step-sister more times than he could count, but none of them had ever been this good.
Tom ran his large hand over her sweat soaked curls, brushing them back from her face. “There’s no need for us to fight, little sister.” Tom placed a soft kiss to the side of her head. “I made you feel better, then you made me feel better. That’s what brothers and sisters are supposed to do, Hermione.”
Hermione stayed laying on the bed as Tom slowly pulled himself from her and a thick stream of white cum leaked from her red cunt. He ran two fingers over her, gathering it up and pushing it back inside her. Hermione’s back straightened and she closed her eyes with a small moan as his fingers sank into her.
“You like that?” Tom asked mildly. “I’ll let you keep it.” He pulled his cum coated finger back and pushed them in again, loving the reaction it caused in her body because every time he did, she gave a small shake and lifted her hips ever so slightly up, making each swipe easier for him.
“You think you can cum again?” Tom asked, interested to see how many times he could work her cunt to orgasm in a single session.
Hermione lifted her head just enough to look back over her shoulder at him before softly nodding her head.
Tom’s face broke into a gleeful smile, nothing fake about this one. “Okay,” he said excitedly. “Lay back down and let me fuck my cum back into you.”
Hermione laid her head back down and spread her legs a little farther. Tom was still grinning as he gathered up a bit more that had slipped out and slid down to her clit. She gasped when he touched it and Tom wondered how many times he could make her cum just from touching her clit alone. He would find out later, right now he wanted to fill her cunt back up and make it leak his cum out again as she orgasmed.
It didn’t take long, Hermione was already so sensitive that within a few strokes of his fingers, she was shaking, her hips bouncing as her body was wracked with pleasure. Tom watched, entranced, as their moistures mixed together and ran out over his hand. As she slowed to a stop, Tom could clearly see the bright sheen of sweat coating her back, pooling in the dips above her ass.
He pulled his fingers from her, letting a trail hang between the tip of his middle finger back to her gaping cunt where he watched his cum leak out of her in thick drops.
Hermione’s eyes gently closed, her body worn and weary from his use of her. Tom stood up and positioned her on the bed properly. Then he pulled his shirt over his head, letting it ruffle his dark hair and removed his jeans the rest of the way until he was just as bare as she was.
Tom slipped into the bed beside her, pulling the comforter over the pair of them. Wrapping his arm around her, Tom pulled Hermione close to him and she instinctively nuzzled into his chest, her breath ruffling the thin line of dark hair that ran down the middle.
Tom kissed the top of her head and whispered, “Get some rest, little sister. Tomorrow is going to be a big day for you.”
Hermione gave a small noise of acknowledgement and Tom sighed happily. They would spend the rest of this weekend bonding, like they should have been all along. For the first time since his mother remarried, Tom liked the idea of having a little sister.
