Summary
     Bon and Rin are in the cram school library. As usual, Rin has no
     interest in studying. Shenanigans ensue.
Notes
     See series page for continuity info and disclaimer.
“You’ve been staring at my ass.”
Ryuuji blinked and refocused, startled as much by the fact that he had indeed
been staring as by Rin’s comment. Well, yeah, because it was not a bad ass,
tail and all, and with Rin standing on the library ladder, it gave him a really
interesting angle. “So what?” Shifting his attention deliberately, Ryuuji
turned the next page. “And this is a library. Shh.”
Rin gave up his desultory poking through the books and slid down the ladder’s
railings, landing with a quiet thump. He sidled over to lean against the
bookshelf next to Ryuuji, stretched up to bring his mouth closer to Ryuuji’s
ear, and purred, “It makes me horny.”
“A light breeze makes you horny.” It wasn’t too much of an exaggeration; Rin’s
sex drive was crazy. And thinking about Rin being horny was making him horny,
damn it. It didn’t help that they hadn’t managed much more than necking and
urgent groping over the last couple of weeks while they waited for Ryuuji’s
banged-up ribs to finish healing.
Rin’s tail was slapping in measured rhythm against his lower leg: thwack,
thwack, curl. “So what’re you gonna do about it?”
“Like it’s my responsibility.” Ryuuji stared at the book in his hands, trying
to remember what he was supposed to be researching. The fluffy tip of Rin’s
tail had managed to worm its way up his pant leg and was squirming against his
ankle, which should not be nearly as arousing as it was. He glanced at Rin in
spite of himself; Rin was smirking, a taut grin that turned almost feral as he
caught and held Ryuuji’s gaze, a fierce, smug look that said, clearer than
words, Gotcha. It pissed Ryuuji off, but it also sent a rush of heat through
him, lit a fire deep in his belly, as if anger and desire were somehow wired
together.
In the library, for God’s sake. But it was the cram school library, not the
main campus library, which meant that it was low traffic and quiet. And at the
moment, apparently empty.
He couldn’t believe he was even thinking about doing this. But Rin’s eyes held
a dare and a promise—fuck if he was going to back down, and oh God, he was
turning as crazy as Rin, because the prospect of doing it here, right here,
right now, had suddenly become insanely hot. And with the pictures already
playing out in his head, it had the potential to get even hotter. If Rin would
only cooperate.
Turning, he shoved the book back into place on the shelf, then seized Rin by
the collar. Twisting his fingers in the fabric, he pulled Rin even closer as he
leaned forward, bringing them face to face. “What am I gonna do? I’m gonna jerk
you off and watch you come,” he growled, low in his throat. “And then you’re
gonna blow me.” Rin’s eyes widened for a startled instant, then went a little
glazed, the thought clearly holding him transfixed.
I want to see that look you get when you’re so gone, when it feels so good it
drives you out of your mind. Want to see you with your mouth wrapped around my
cock for real, oh hell, yeah.
You want to play games—are you ready to face the consequences?
Rin’s gaze sharpened again—his eyes locked with Ryuuji’s and his smile blazed,
eager and hungry, as if he’d heard Ryuuji’s thoughts and was answering their
challenge. With a sharp, decisive nod, he cupped his hands behind Ryuuji’s head
and dragged him down, arched up to kiss him hard, to rub up against him, breath
already coming fast against Ryuuji’s mouth. Ryuuji felt his dick twitch at
Rin’s blatant excitement; he pressed his hand to the front of Rin’s pants and
found Rin already swelling, feverishly anticipating his touch.
Oh yeah. Oh...yeah.
With a ferocious smile, Ryuuji slowly undid the button of Rin’s pants.
He couldn’t have hoped for better.
 
 
 
Konekomaru checked the next title on his list, then tucked the folded piece of
paper back into his shirt pocket and hefted his pile of books. Just one more
and he’d probably have everything he needed for his research paper. He made his
way through the stacks, scanning the signs at the end of the rows of shelves in
order to find the right section. The organization of the place was a bit
quixotic.
He wasn’t sure what caught his attention first, a hint of movement or some
faint sound just at the edge of hearing, but as he glanced down the aisle, he
recognized the two figures standing there. Pleased, he opened his mouth to
greet them, and then paused.
At first he thought they were fighting again. Bon had his back pressed up
against the shelves; Rin was leaning into him, both fists clenched in his shirt
front. Bon looked intense, though strangely so, staring fixedly into Rin’s
face. Then the peculiar look on Rin’s face registered: eyes closed, mouth
parted in nearly silent gasps, his expression strained and wild, so that
Konekomaru wondered, with some alarm, what on earth was wrong with him. He
thrust up against Bon, both of them rocking with the motion, his hips jerked,
and Konekomaru suddenly realized that Bon had his hand shoved down the front of
Rin’s undone pants.
Down his....
It was like a car crash in his brain, the hurtling realization and then the
stunning jolt of collision. He could only stare as Rin swayed, his whole body
responding to the aggressive, methodical movements of Bon’s arm, as Rin
swallowed and then moaned, his fingers uncurling on Bon’s chest and then
knotting once more. The tempo increased—Rin shuddered violently, made a
strangled sound, as if choking back a shout, and Bon’s other hand tangled in
his hair to tilt his head back as he stiffened, jerked again, his face going
tense as if with great pain before relaxing into a look of extraordinary,
overpowering release. After a moment, Bon let go of his hair, and he crumpled
forward, gulping for breath, whimpering a little as Bon’s hand continued to
work him, slowly now, a gentleness at odds with Bon’s predatory, self-satisfied
smile.
Bon withdrew his hand at last, pulled out a pack of tissues, and began wiping
his fingers, still looking inordinately pleased with himself. Rin’s breathing
had slowed; he straightened slightly, lifted his head to stare up at Bon. Their
gazes met, and suddenly Rin was smiling too, as fierce as Bon if not fiercer,
as he began to sink downward, as he reached out to undo Bon’s very full pants—
Konekomaru snatched himself back around the corner. He pressed his back up
against the end of the bookshelves, his teeth clenched to stifle a yelp of
shock. He could hardly think over the pounding of his pulse in his ears, but
even if he’d been able to think he still would have flailed around trying to
believe it.
Could never have imagined it—
Bon and Rin...like that....
Oh God, the look on Rin’s face...and those sounds....
Behind him, Bon let out a low, rumbling sigh, a deep hrrrr of satisfaction, and
Konekomaru began tiptoeing away as quickly as he could, trying to salvage
whatever innocence he had left.
He wondered if he could ever look either of them in the face again.
 
 
 
His heart rate had barely even begun to settle, and it was already picking up
speed again as he drew Bon out, his hand wrapped around Bon’s very hard, hot
length. He was actually going to do it—he’d sort of fudged it the last time,
but this time he was really doing to do it. Suck his cock. Take it right into
his mouth. Kind of scary, kind of strange, but he wanted to do it, wanted to
give Bon back all the pleasure he’d just gotten and more, wanted to make Bon
come and come—come fucking hard, more than the smug son of a bitch had
bargained for—and as much or more than that, he wanted it. Wanted to know what
it was like. Wanted to cross that line. Wanted to pull them even closer
together, closer than they’d ever been yet, and there wasn’t much closer you
could get than inside—oh God, thinking of it like that made his stomach turn,
not with sickness but with something like an aching hunger, and he didn’t know
why it was so hot but it was, just like Bon being so totally turned on just
from seeing him come was hot, awesomely hot, and he wanted things to just keep
on getting hotter.
So freaking much wanting, he almost couldn’t stand it.
It hadn’t been hard to kiss Bon—it had been nice, better than nice, fantastic.
It hadn’t been hard to get used to touching his dick—he liked the way it lay in
his hand, the weight of it, liked the way Bon shifted, letting out a low breath
as he rolled his thumb around the edge of its slick head. So this wouldn’t be
hard either, right?
“You’re too tall,” he said, and his voice sounded thick to him, a little
hoarse. Not like he was nervous, though. “Crouch down a little.”
Bon bent his knees slightly, bracing himself on the bookshelf. “Better?”
“Yeah.” He could’ve managed, but this would be easier. As long as Bon’s legs
held out. Shifting forward, he let his tongue play around the rim of Bon’s
head, then lick at its underside, his lips barely grazing the skin. Yeah, just
like kissing, really. He opened his mouth wider, then a little wider—
“Watch the teeth,” Bon warned, somewhat breathlessly.
“Hmph.” Both annoyed and amused by the interruption, Rin drew back, then
lunged, pretending to take a chomp out of the side of Bon’s dick. “Nom!” Bon
jumped with a hiss of fear and displeasure.
“You—“
“Aww, don’t worry,” Rin crooned, petting the threatened member soothingly, as
if it was a small, cute animal. “I wouldn’t hurt Bon-chan.”
“B-Bon-chan?” Glancing up, he saw Bon’s face go dark with fury, his eyes
blazing wrathfully. “Die.”
“Ah-ah! Can’t kill me yet.” Rin smirked. “I haven’t gotten you off.”
“Then hurry up,” Bon snarled, settling himself back against the bookshelf.
Rin snickered and repositioned himself. Luckily the scare hadn’t shriveled
Bon’s hard-on. Teasing aside, though, he could see how teeth would definitely
be an issue, and especially his teeth. Stupid, pointy fangs...so how exactly
was he going to do this?
Very, very carefully, he decided.
 
 
 
Ryuuji set his jaw hard, holding back the moan that wanted to escape him as Rin
began taking him in slowly, so slowly—maddening, he wanted to explode, but also
absolutely unbelievable, to feel himself pushing bit by bit into the heat of
Rin’s mouth, between Rin’s amazingly soft lips. They wrapped around his head,
then pulled back over its rim with a little pop, did it again and then again, a
shallow mouth-fucking, forward and back, while Rin’s tongue traced lazy circles
over the end of his cock. So little, but it felt so insanely good. More,
dammit. No, don’t stop, as Rin drew back and released him, letting out a
breath—flutter of air on his wet cock head, and he did make a sound then, a
catch in the back of his throat. Rin glanced up at him, then leaned forward and
breathed more deliberately, sending a shudder running up and down his spine.
Gasping, he glimpsed the flicker of a smile on Rin’s lips before they opened to
take him once more.
Deeper now, and more sure, more eager, Rin’s tongue squirming beneath him,
extending and retreating as if to lap him up, to draw him further in, Rin’s
lips sliding down along his shaft, oh God, just like he’d wanted it, the barest
graze of teeth before Rin caught himself and corrected it, but Ryuuji hardly
even cared, he was in fucking heaven. He gripped the bookshelf behind him as
tightly as he could, fighting the urge to jerk his hips, to pump himself even
deeper into that exquisite mouth. He didn’t know how long he could hold out.
And now Rin’s head was moving back and forth, his lips stroking Ryuuji’s cock,
its head brushing the roof of his mouth, the arch of his tongue—so good, so
good, only one thing in the world could make this any better, and Ryuuji let go
of the shelf with one hand, reached out to push Rin’s hair aside so that he
could see it all, the tight O of Rin’s mouth enclosing him, rubbing against his
skin, the stretch of Rin’s jaw, the beautiful surrender in his face.
Rin looked up from under his eyelashes, meeting Ryuuji’s gaze—he couldn’t
exactly grin in his position, but his eyes danced. And then they closed, and
Rin moaned around him, as if Rin was the one who was getting perilously close
to coming. He started sucking ecstatically, letting out little whimpers and
grunts and mmmms, ridiculous, indecent noises, but oh shit—it could get even
better, because that—those sounds, they went right into Ryuuji, sending his
arousal burning out of control, white hot and all-consuming, especially when
the rocking sway of Rin’s body, the growing expression of bliss on Rin’s face
started to tell him that it wasn’t just mind games anymore, it was real, Rin
was turning himself on with this, loving it, ah—
Rin’s hand curling around his cock, his other hand groping to fondle Ryuuji’s
balls as they tightened, as Rin sucked hard—
He came so violently that his knees almost buckled; he had to grab onto the
shelf again, fumbling to find his grip as his whole body convulsed. Pleasure
like fireworks going off, the spasms of his come shooting out of him—into Rin’s
mouth, oh yes, yes, take it—he didn’t know how long it lasted, but it seemed
like forever, and at the same time not long enough. Couldn’t ever be long
enough. And then it was fading, and he was propping himself up against the
books, shaking a little, breathing hard and wanting to laugh because oh damn,
that had been the most fucking amazing thing he’d ever felt.
Rin released him with a final tongue laving and sat back, wiping at his mouth.
Just a small dribble had escaped, which meant that he really had swallowed it,
a thought that gave Ryuuji an extra squirming twist of satisfaction. Rin slid
back further, leaned back on his heels as he slowly spread his fly wide and
drew himself out, stone hard again, as he began stroking his flushed dick with
both hands, his eyes shut, lost in his own need. Ryuuji could only stare at
him, stupefied, drinking it in. Memorizing that sight, so he could let it play
over and over in his fantasies—but why just fantasy, maybe he could get Rin to
do this again, sometime when he hadn’t just shot his load, when he could jerk
himself off to the sight of Rin on his knees before him, masturbating with
single-minded intensity...and would Rin actually let him come on him?
Shit, they were dirty thoughts. But were they any more dirty than Rin fucking
his own hands on the library floor, his knees spread wide apart, his tongue
flicking across his parted lips as though he was still imagining Ryuuji’s cock
filling his mouth. The rhythmic lift of his hips as he arched his back,
straining; the shift and roll of his shoulders, his whole body moving to the
pulse of his clasped hands; his lips fluttering back from his bared teeth as
his face scrunched up, soft, guttural, animal sounds spilling from him. His
pace increased, became frantic—he stiffened abruptly, grunted, then threw his
head back and came, as hard and long as if he hadn’t come in forever,
splattering the floor in between them.
Ryuuji let out a shaken breath. He’d forgotten that breathing was even
necessary; maybe that was why he felt dizzy. Oh shit, who was he fooling? That
had been...completely and utterly mind-blowing. He was probably lucky he hadn’t
gotten a nosebleed or passed out. Hunched over on the floor, Rin was catching
his own breath. With a sigh, he straightened and looked at Ryuuji, his eyes
half-lidded, a crooked smile quirking his mouth—a little bit knowing, savoring
the effect he’d had on Ryuuji, a little bit rueful, as if admitting his own
crazy, but for the most part just satisfied and spent. At least for the moment.
Ryuuji started, coming back to himself. Hastily he pulled out the tissues, took
a couple for himself, and tossed the pack to Rin. He didn’t really need much
cleaning up, though. Rin had pretty much taken care of him. In silence they put
themselves back together—and then Rin surged to his feet, thrust Ryuuji up
against the bookshelf again, and kissed him, lingering and deep. He tasted salt
in Rin’s mouth and realized with a shock what that was. Instinctively he pulled
back.
“Don’t like it?” Rin’s eyes glittered as he smiled slyly. “You get used to it,
though.” He tugged Ryuuji forward again, and after a moment’s resistance Ryuuji
let him, kissed him back with determination, refusing to let squeamishness get
the better of him. The smell of sex on Rin’s breath, on his hands, cupped
around Ryuuji’s face, Rin’s eager, skillful tongue stroking against his...it
occurred Ryuuji that he was probably not really that far off from getting hard
again, and then nothing whatsoever was going to get done. With an effort, he
pushed Rin away.
“Enough fooling around,” he croaked. Clearing his throat, he added sternly,
“Get back to work.”
Rin stared into his eyes, as if measuring his strength of will, then made a
face. “Che. Yeah, yeah. All right.” Stretching, he slung the strap of the
Koumaken over his shoulder and wandered off, reeling a little, loose limbed and
still sex-drunk, and probably about to find a desk and chair somewhere so he
could fall asleep, the slacker, while other people did their homework. Rin’s
tail swished languidly behind him, curling with lazy, sated contentment.
And he was still staring at Rin’s ass, Ryuuji realized.
