Clary hardly registered where they were going.

All she knew was Sebastian's arms and her own haze of both pain and pleasure.

She knew they'd ascended because of the change in light, but had neither the strength nor the willpower to lift her head from where it was buried in Sebastian's chest.

After what could've been minutes or millennium, she felt herself being laid on the softest sheets imaginable.

Like clouds or perhaps a marshmallow, she sunk into their embrace with a shallow moan, head nestling into a pillow.

She heard the door close and Sebastian moving about the room, but she drifted in and out, in a haze where she was both utterly exhausted yet sexually awake.

Finally, she felt the bed shift beside her.

"I'm going to give you that massage, Clarissa."

Clary only made a half-sound in response to her brother's statement.

A clink was followed by the odd feeling of slick and slow wetness on her back as large, hard hands were spread over it.

Oil, she realized, suddenly. He was using oil to massage her.

Sebastian started at her shoulders, kneading them deeply and thoroughly, moving slowly downwards, making Clary slump farther into the bed as her muscles went completely slack.

Knead after knead of his hands had Clary ascending to a higher plane of bliss and relaxation.

When he got to the curve of her ass, the clinking of the bottle sounded again and oil dribbled down the cheeks of her ass and slowly trailed down the cleft.

Clary stiffened, but Sebastian's kneading of her should blade area had her relaxing yet again.

Sebastian slowly worked his way back down to Clary's butt, finally smearing the oil there across both cheeks and kneading them firmly in his hands.

Clary moaned softly, face buried into the pillow in relaxation.

Despite herself, Sebastian's capable hands on her ass had her growing wet.

Sebastian kneaded harder, before spreading her cheeks apart under his watchful gaze.

Clary once more stiffened as the oil he'd poured earlier congealed in her asshole.

And yet once more, Sebastian's capable hands kneaded it away.

Then, spreading her thighs father apart, he sat on the backs of them while his knees rested on either side of her languid form.

Clary couldn't move her legs, and started to tense again, a protest at her lips.

"Shhh," Sebastian chided, resuming to massage her upper body, making the muscles supple and pliant underneath his capable hands.

And Clary calmed again, as if his hands had somehow hypnotized her into complacency.

Sebastian moved down to her waist, massaging the sides slowly and purposefully, before working his way up until his thumbs brushed the undersides of her breasts.

Her nipples pebbled at the attention, growing hard against the sheets beneath her.

Yet he went no further besides gently running his thumbs beneath her breasts as he massaged her sides.

Again, oil was dribbled on her back, and Sebastian spread it deftly, working it down her butt and to the tops of the back of her thighs.

Clary's body was sending mixed signals, both relaxed beyond belief and on edge with sexual anticipation.

Slowly, Sebastian's hands drifted down, firmly massaging the back of her thighs, creeping slowly towards her inner thighs.

His hand brushed her folds, found them wet, and smiled - but Clary couldn't see that of course. Couldn't see the devilish grin on his face or the lust in his eyes.

And even if she could, she wasn't sure if she would've stopped him.

Grabbing more oil, he slowly began to rub her slick folds, every so often brushing that bundle of nerves that made Clary pant in want.

Her labored breathing and the slick, wet sound of her oiled folds filled the air, along with Sebastian's low and dark chuckle.

He leaned over her prone form, scraping his teeth over her neck and the junction of her neck and shoulder.

He placed open-mouth kisses on her, laved at her sticky sweet skin with his tongue.

His hands drifted upwards, once more firmly massaging the globes of her ass.

His hand drifted to the cleft of her ass, smoothing oil down it, before he spread it, baring her asshole to his eyes.

"What a pretty hole," he murmured, massaging the oil into it, making Clary arch slightly in response.

But when he tried to slip his finger in, Clary clenched her ass muscles and prevented it, trying to scoot away from him.

Sebastian chuckled darkly at the challenge, dragging her back under him as he leaned over her.

"Are you gonna open up for me, Clary?" Sebastian whispered in her ear, nipping it with his teeth.

Clary shuddered, gasping for breath, sure of what her body wanted but at odds in her mind.

"Are you gonna open up your tight little hole for me?"

As he said this, Clary felt his thumb ring her opening, before slowly pushing inside, slick with oil.

Clary moaned at the feeling, unbidden, at him stretching her virgin ass.

He went deeper, probing down, and left Clary panting slightly.

"You want this, don't you Clarissa? You want your big brother to press his big dripping cock into that puckered little hole of yours and take your ass for the first time."

Clary moaned in response, though if it was because of his words or his undulating pointer finger in her ass, she wasn't sure.

Sebastian stretched her cheeks father apart, and her asshole, and she felt the warm slick of oil entering, spread by his fingers.

"We want you nice and slick for this, little sister," he murmured as he spread the profuse amount of oil in her asshole and around it.

Clary moved her hips in gyrating motions to the rhythm of his fingers, wanting more, more, more.

Sebastian smiled darkly at having her hooked on his attentions.

He shucked off his clothing quickly enough, leaving him as naked as he was born.

He resettled over his sister, pink cock erect and weeping profusely at the sight of her spread out and compliant for the taking.

He slowly ground his penis against her slick folds, lubricating himself, before starting to fuck the cleft of her ass, oil coating him and making them both slick now.

Clary rocked back against him as he rutted against her, head thrown back with eyes closed.

But Sebastian had barely started.

He spread her ass cheeks apart again, and prodded at her hole with his cock.

Clary stiffened, at once realizing what he intended to do.

"Sebastian-"

"Shhhh. Just relax and open up for me."

And with that, he slid the tip of his cock into her puckered hole.

"Ahhh!" Clary groaned out, both simultaneously in pain and pleasure.

Sebastian held himself up above her, watching where her tight hole struggled to take his girth.

Slowly, he inches farther and farther in her ass, Clary making a multitude of noises as he did so.

Finally, he was seated to the hilt in her, and Clary had seized panting.

Sebastian pulled back and slammed back into her ass.

Clary groaned out an unintelligible jumble of noises and words, and he did so again.

Each time he did so, the slick and location made a dirty slurping sound that had Clary flushing pink.

Sebastian continued to fuck her ass, kneeling over her and pulling her ass up to meet his hips as he did so.

Clary was sobbing into her pillow, unable to describe how good a feeling this fullness felt - even better than Jace had.

With a hand, Sebastian reached down to massage her engorged clit in time to his rampant thrusts into her ass.

Clary found herself climbing higher and higher, her legs shaking and heart racing, until Sebastian cruelly flicked her clit. Clary saw white and came all over his hand with a series of indecent moans.

Sebastian continued to pound into her ass for another minute, before he shoved himself to the hilt and painted her insides white with ropes of his cum.

He stayed there for a good while, enjoying the clench of Clary's ass around his spent cock.

When he did pull out, cream dribbled down Clary's ass and into her folds, mixing with her own release.

Sebastian laid on top of her, mouth nestled at her ear.

"I told you that hole would be mine."
