Sengo/Ishiko

[amatorii]

"You're incorrigible," is the thing most commonly said about Sengo, because he's too charming for "you're despicable."

Unsurprisingly, when he comes home after the first semester of his sophomore year in college, he hasn't learned any life lessons or matured. A girl he introduces as his girlfriend comes down with him, and several hours of loud music not quite covering the muffled moans and squeaking bedsprings ensue - but before she's even had the chance to stay over one night, it turns out Sengo had been dating her all of eight hours, and her parents were worried when she didn't get off the train as scheduled on her way home from break, and there's something of a whirlwind drama as she grabs her things and heads back to the train station.

Sengo shrugs, sighs, heads up to his room, and emerges a moment later, dropping his now ex-girlfriend's crumpled underwear in his little sister's laundry basket. Then he turns to head back to his room, shrugging philosophically. His parents pointedly retreat to their room for the night with the grumbles and glowers he's come to expect, and he stretches out on his still-rumpled bed, wiggling his toes and smiling at the ceiling.

Ishiko has grown up quite a bit over the years. She's still sort of in that slightly awkward teenage phase - gangly limbs and all - but her baby fat is gone and she's more of a slender young woman now than she was a few years ago. Still young, but more of an adult.

She's not looking at him as she slides her jeans off of her hips and steps out of them; all that's left is a bra and a pair of panties, but she stops when she glances up and notices her brother's cock. She murmurs something that sounds like oh and she takes a few steps closer and then settles onto the bed, eyes locked on him. Hes different from her boyfriend.

Pleasantly so.

"Did she do that to you...?"

She means the hickies.

[amatorii]

"Yeah," he says. "It's a hickey. You latch your mouth on tight and suck until it bruises. It feels better than it sounds. You can get them almost anywhere. At least..."

He laughs. "Anywhere that isn't... meant to be sucked on?"

He spreads his legs a little, letting her examine more closely.

"Take as close a look as you want, if you're curious," he offers, because it feels rude to order your little sister to keep stripping. He's seen her in her underwear before, even if he never exactly stopped to appreciate the view.

As he does, now, he continues to get harder.

[palemask]

She is curious. For a long moment she just blinks and then shoots him a look, "I know what a hickey is, I just - didn't realize people left them... there."

She gestures at his thighs, but she also slides a little closer to him until her shoulder presses into his and she leans over to drag fingertips tentatively against the dark bruises on his thighs. Her wrist eases against his cock - brushes the hot, erect shaft and she blushes again, eyes flicking up to see if he notices.

[amatorii]

"Oh, fuck yes," Sengo says under his breath, at just that hint of skin to skin contact, cock stiffening and rising further. "Yeah. Just about anywhere. And they feel good, just about anywhere, as long as you like being hurt at least a little. There's a lot of shit like that... where just a tiny bit of pain feels so fucking good... but you gotta be careful not to overdo it."

He closes his eyes, shivers, savors both the sensation and his own imagination. Then he looks back at her. "You know... you're going to have to lose your underwear... if you want me to show you how he should touch you. Right?"

[palemask]

"I never thought about pain as being something you'd want..." Her eyes flicker up to him and her hand draws back. She's about to open her mouth to ask something else, when he gives her a rather gentle (if pointed) reminder about her current state of dress. She blinks, blushes and then nods silently, feeling a bit sheepish. She reaches behind herself to fiddle with the catch of her bra and then slides it off, revealing bare breasts (and hardened nipples, the flesh pebbled).

Then she raises her hips and hooks her thumbs into the waistband of her panties. There's a moment of hesitation and then she simply slides them off of her hips and down her legs, leaving them in a little pile on the floor. She folds her hands in her lap, knees pressed together.

"...I want you to - to show me what you meant about pain."

[amatorii]

"I can do that," he tells her, his voice soft and even, and he reaches out, fingers curled. His fingertips touch her shoulder, gently, fingernails only, making small divots in her skin, and he draws his hand down her arm, nails skating with only a ghost of pressure at first, then a little more, then more, drawing white lines in their wake.

The whole time he watches her with a steady curiosity, almost distant. He can see his little sister's tits. They're cute, he thinks. Maybe later she'll let him suck on them. Bite them.

Part of him is alarmed at how easily his mind adjusts to these thoughts, but the rest relishes it.

[palemask]

The white lines he draws make her shiver. The touch sends little sparks of pleasure floating through her and she leans in a little closer, resting her head against his shoulder. She takes a few deep breaths, feeling a bit vulnerable. Naked. Well, she's literally naked, but it's more than that. She's doing this with her brother.

Somehow that doesn't seem to bother her and she doesn't know if that ought to bother her.

"Um. Should I - get in your lap or-?"

[amatorii]

"We'll get there," he assures her, and shivers at even the thought. He reaches out and draws his fingernails lightly down the slope of one pert breast, flicking her nipple lightly, teasingly, as he passes it.

"First, though... I just need you to sit on the bed. Facing me. Spread your legs... and show me how you touch yourself."

He hesitates a moment, finally. "You do touch yourself, yeah?"

[palemask]

Oh. There's a shiver from her as his fingers flick against her nipple and it stiffens under the attention, her teeth digging into her lower lip in response. She follows his commands with a shaky little exhale, settling back onto the bed and spreading her legs for him. This feels filthy and taboo and delicious and she doesn't want to stop.

Even if she knows she ought to.

"Of course I do-" She retorts, cheeks flushing, and then she slides her hand between her legs, gently rubbing at her lips at first - a soft little motion to get started, the heel of her hand gently rubbing against her clit. It's slow.

At least to start.

[amatorii]

"Like that," he observes, his voice very soft, and then he's doing what he always would in this situation, leaning forward, his own hand reaching between her thighs to let the soft pads of his fingertips glide up her, just outside her lips, teasing and coaxing, up and down. He waits, patient, for her reaction. This is what she wanted to be shown, isn't it? How her boyfriend should be helping her.

[palemask]

"Oh," she murmurs in a little voice as Sengo's hand presses against a thigh and then closer and closer to her sex. Her body starts to tense and her eyes flutter shut as she slides first one finger and then another into herself. It's a strange feeling, being watched and having another's fingers against her as she pleasures herself. But it's not bad.

"That's - that's good-"

[amatorii]

"If you put on a show for your boy," he explains, his fingers still moving carefully to touch with the same rhythm, the same pressure as hers, complementing hers, "you can show him what to do. If you need... a lot of clit contact... you either want his hands on you while he fucks you... or a position where you can... can grind on him."

[palemask]

There's something so intimate about having his hands on hers as she touches herself; it adds an entirely new dynamic. One that makes her stomach churn and clench in the most wonderful of ways and she has to stifle a little cry by biting into her lip.

"I - I like both. I like feeling hands on me, I like it when I'm teased - ah-"

A pause, her face flushed.

"How would you tease a girl? Can you show me?"

[amatorii]

"I think this is the first time you've actually asked me to tease you," he says, laughing a little. He has always been a terrible tease of a brother, after all, but this...

He scoots closer to her, but his fingers stop teasing her labia, giving her mons a soft, condescending pat with his hand. He's close enough now that it's easy to shift so he's not on the edge of the bed, to put his hands under his little sister's armpits and lift, shifting her, smiling at her for a moment before he sets her in his lap, straddling him.

"You want to be teased?" he asks, something warm and possessive in his voice. "I can tease." He puts his hands on her breasts, and tweaks her nipples, playful, but hard, enough to redefine that edge between pleasure and pain. "No more playing with yourself. You want to feel something, you better grind. You want to be touched, you'd better beg... and find a way to pay for it. Is that what you need?"

His conscience, his worries, have vanished. There's a lithe, willing girl in his lap who wants to learn, wants to be tormented, wants better orgasms in her life. He's never ever turned that down. The age gap doesn't matter (he wonders if she knows how many of her friends he's fucked). The fact that she's his sister doesn't matter. Or... maybe it does. Maybe it makes this all better.

[palemask]

Her hands go up and settle on his shoulders as he settles her in his lap. She has a flushed face by now and her head is spinning. She's done this sort of thing with her boyfriend, of course, but this still feels so different. More intense. Her head is spinning and she can't quite get anything to slow down long enough for her to think. Instead, a mix of pleasure and pain goes shooting through her as his fingers tweak and tease at her nipples. She whimpers and leans in to bury her head against his throat as she gasps for breath.

The way he talks to her is dirty. It's filthy.

She loves it.

Her hips hitch and then she grinds herself against him, rolling herself against the length of his cock, dragging herself up and then down, desperate for some sort of friction. Some sort of heat.

"Sengo, please-" She feels so needy; like she's burning up underneath the skin.

"Touch me!"

[amatorii]

"Touch you where, honey?" he asks, cruelly solicitous, and still half breathless as she rolls herself against his cock, groaning as his voice catches between words. "Say it. Tell me. Tell me exactly what you want."

He tweaks her nipples harder, then leans forward with a stuttered laugh and kisses her, his mouth open and eager against hers. His cock is aching, skin hot, and he's longing already to be buried inside her - but he can wait. He can wait, if it's to let him show off just what he can do to her.
