A/N: I was gone for so long asdfghjkl. My apologies. I was (still am) sick and coughing all over the place, and then school got super busy. But... I am back! Thanks for all the feedback and comments, they make my day! Enjoy!

James Carstairs, Will had decided, was an absolute tease. It was simply unfair, sitting next to him at breakfast and trying to ignore those looks. Jem and those wide silvery eyes would be the death of him, he guaranteed it. Will doubted Jem even knew what he was doing- his parabatai was endearingly innocent in all things regarding love, particularly the physical aspects. Will had been the first person he'd ever even held hands with.

Will was quite a bit more experienced, though most of that was caused by too much alcohol and too many lonely nights in the bad part of London.

He didn't feel experienced at the moment, however. He felt like some lovestruck teenage girl, staring at Jem and feeling his desire rise. He hadn't seen him since yesterday afternoon, as Will had been dragged off on some mission Jem was not quite well enough for, and hadn't kissed him since before even that. Will had gone to his own room upon his return, not wanting to wake Jem, but now...

'If we weren't in the dining room with everyone else here...' Will thought, fighting back a blush at the direction of his own thoughts.

"Will, did you hear a single word anyone has said in the past five minutes?" Charlotte's irritated voice snapped Will out of his daze.

"No," he answered truthfully. "What's happening?"

Beside him, Jem grinned. "You and Henry are kindred spirits," he said, nodding his head towards the red-headed man, who hadn't even glanced up from his paper at the mention of his name.

Charlotte threw her hands up in exasperation. "Jem, please tell me at least you were listening to me," she huffed, thoroughly frustrated.

Jem gave her a sweet smile. "Of course, Charlotte."

"Good. Will, I suppose you'll have to piece it together as we go. Come on, both of you."

Will and Jem both stood, Jem's hand brushing his own as they walked into the hall. Will felt every nerve in his hand stand on end at even this smallest brush of contact.

"So, what's Charlotte going on about?"

"You'll figure it out," Jem said, eyes dancing with amusement. Then, as quickly as could be, Jem stood on his toes and kissed Will's cheek before walking after Charlotte.

Will, who'd stopped dead in his tracks with a hand pressed to his cheek, stared after Jem, enjoying his view. Will whistled lowly and saw the tips of Jem's ears flush pink with mild embarrassment.

Halfway down the hall, Jem turned partially, beckoning to Will to come with him. The spark in his eyes, the nerves in Will's hand and face still singing, the little beckoning gesture, Will's mounting desire... it was all too much. He was going to have to steal Jem away very, very soon.

~•~•~•~•~•~•~•~•~•~•~•~•

As it turns out, Will didn't get his chance to steal Jem away someplace private. Charlotte gave them each a stack of dusty old documents to sort through, looking for anything that might be relevant to the current investigation.

Bored out of his mind, Will let his head drop to the tabletop and groaned.

"Jeeeeem," he complained, drawing out the name until Jem finally looked up.

"Yes, William?"

'He knows I love it when he says my name like that. He's doing this on purpose,' Will thought, forcing himself not to pin him against the wall then and there.

"I'm bored," he said aloud.

Jem ran a hand through his silvery hair, causing the light to catch on it. "And just what do you want me to do about that?" Jem's words were innocent enough, but there was a slight smirk on his lips and a raise in his eyebrow that lent another meaning.

'He will pay for this teasing, by the Angel.'

"You could entertain me," Will suggested, dropping his voice to a low murmur that almost always got a blush from Jem.

This time, however, it earned him merely a wink. "Patience, Will."

"Maybe I don't want to be patient."

"Then maybe I don't wish to entertain you."

Will raised an eyebrow. Was James Carstairs going to play hard to get? That was new.

"Jem," Charlotte called from the other end of the library, sounding a bit embarrassed, "Can you get this down for me? Henry put it up too high, and I'm not certain where he put the ladder, either."

"Probably down in the crypt, trying to get it to self-expand and retract and spontanteously combust. The usual," Will mumbled. Jem laughed softly, a bright and clear sound that made Will smile in return.

"Coming, Charlotte," he said through a laugh, standing and crossing the room to her. "What exactly do you need?"

"The book with the blue cover. The one in Latin," she said, standing on her toes to point.

Jem was by no means short- he stood just a hair taller than Will, though he didn't look it because of his slight frame- but even so, he had to rise up onto his toes and stretch to reach it. In doing so, his shirt slid up an inch, revealing a strip of porcelain skin just above the waistband of his pants. Will knew the skin there to be delicate and sensitive, and the slightest of touches there would make Jem shiver. These pants hung deliciously low on his hips, and if Will could think of anything other than how much he wanted Jem at this moment, that may have worried him... He was fairly certain those did not fit so loosely a month ago.

But all he could think about right now was how much he wanted to lay a hand there, against the bare skin, and feel Jem shiver under his hands, hear the little sound of indignation before it was silenced with a kiss...

Will came back to reality with a start. No use fantasizing. Not in the library.

"Oh, for heaven's sake, Henry, why did you put it up here?" Jem mumbled. With one final stretch- sending his shirt up just one little bit more- Jem handed the book to Charlotte, turning and walking back to his own stack of documents.

Just as Will heard the creak of the floorboards that meant Jem was right behind him, there was a light, cool finger tracing up his spine. On instinct, Will sighed and relaxed back into Jem's touch. The teasing little devil laughed softly and carded his violinist's fingers through Will's curls, giving a slight tug to the end of them in the way he'd discovered made Will gasp.

And this time was no exception. Will's eyes flew open with a little helpless gasp. Trying to mask his slip, he cleared his throat and pretended to be very, very, interested in the old set of records.

The coy smile his so-called angel gave him as he sat back down told him it wasn't a believable cover.

~•~•~•~•~•~•~•~•~•~•~•~•

'This,' Will thought, groaning internally, 'is absolute torture.'

The rest of the morning and much of the afternoon had gone on in much the same manner, with Jem missing no opportunity for a remark or a small touch or showing any of his impossibly beautiful skin, and Will suffering for it greatly.

When Charlotte finally thanked them and said she didn't need their help any longer, Will wrapped a hand around Jem's wrist and pratically dragged him out of the library.

Jem flashed him a knowing smile. "And what's got you in such a hurry, Herondale?"

"You know perfectly well what, James Carstairs," Will said, fumbling with the handle and shouldering his bedroom door open. "You've been nothing but a tease all day. And now it's time to pay the price of your mischievousness."

Jem opened his mouth as if to protest, but Will cut him off with a kiss, pushing him back against the wall. Jem gasped and said something, but Will didn't hear it. He was too caught up in finally, finally having Jem's lips against his own and feeling that thin frame wrapped tightly in his arms.

Will pulled the two of them closer together, Jem's back firmly against the wall. "Why," Will said lowly, hands resting at the hem of Jem's shirt, "Were you being such a tease all day?" He had been expecting some innocent, clear-eyed response, some very Jem-like response.

Which was why he was surprised when Jem ran his fingers through his curls and pulled them into a searing kiss. "Because," he said, slightly breathless, "I knew it would end like this."

Will pulled back just enough to be out of reach. "I've half a mind to leave you alone tonight, Carstairs."

This merely earned him a raised eyebrow. "And punish both of us? Come to bed and stop your bluffing."

"How forward of you," Will said, arms going around Jem's waist, "And I thought you were the innocent one."

"You, of all people, should know I'm anything but."

Will smiled and kissed him slowly as they made their way to the bed, both unwilling to part for even a moment. Jem's hands trailed down to Will's waist and quickly divested him of his shirt, breaking away only to pull it over his head.

Will shivered as Jem's cool hands rested on his chest, idly tracing the parabatai rune with one finger. They fell onto the bed, a tangle of limbs and kisses and quiet whispers.

"I love you," Jem murmured, kissing along his jawline sweetly.

"I love you too," Will replied. "Even if you are a tease." Slipping his hands under Jem's shirt, he made short work of it, tossing it carelessly to the floor.

Soon enough, anything separating them had been removed as Will trailed kisses down the column of Jem's neck, nipping gently at the sensitive skin there. Jem shivered, blushing, and tangled his fingers in Will's hair. Will bit down harder, making Jem gasp. Almost inaudibly, he moaned Will's name and managed to speak a coherent sentence.

"No marks above my collar," Jem said breathlessly.

In response, Will simply continued his pattern of soft kisses intermingled with rough bites down Jem's chest, pressing his lips to every mark and scar.

"You," he said, kissing the parabatai rune that bound them, "are so, so beautiful, cariad." The Welsh endearment came so naturally, just as Jem's soft phrases in Mandarin always seemed to.

A faint blush appeared across Jem's cheeks as he shook his head. "You sweet talker."

"It's effective, you must admit."

Jem rolled his eyes. "Oh, hush."

Will captured his lover's lips in a kiss, feeling Jem's arms wrap around his neck and draw him closer.

Will carefully grazed his teeth over Jem's bottom lip, smirking with satisfaction at the soft sound Jem made in response.

"Now look who's a tease," Jem complained breathlessly as Will pulled away with a smirk, trailing his hands down to the sensitive skin at his waist.

"Ah, but I plan to follow through with mine," Will said. Before Jem could say anything else, Will kissed him fiercely, biting his lip harder than before.

Jem gasped and moaned his name, lips parting in surprise. Will cupped Jem's face in his hands and deepened the kiss, slipping his tongue into Jem's mouth. Forcing himself to be gentle, he   moved to straddle his hips, never letting their lips part.  Jem moaned and shivered, raking his fingers through Will's dark curls and tugging lightly.

Will smiled faintly, letting himself go in everything that was Jem. Their kiss quickly became more and more heated as the two of them forgot all boundaries of propriety. Both quickly lost control of themselves as their kiss became passionate and desperate, as if this was their last night.

Will's hands wandered downward steadily as they kissed, and he managed to have the awareness to pull away and look at Jem for permission before he crossed a line.

Jem peered at him as he pulled away. "You okay, love?"

"Yes. I didn't want to take liberties if you weren't comfortable with it..." Will said awkwardly, looking away.

Jem smiled and interrupted Will's awkward rambling.

"Take them, my darling."

~•~•~•~•~•~•~•~•~•~•~•~•

Will lay on his back on the bed, Jem curled up beside him and resting his head on Will's bare chest.

Will knew they'd both regret this if they had a mission tomorrow when they woke up sore, and that there were marks that would be hard to explain if someone saw them, but right now... he was happy.

Jem shifted slightly and sprawled across Will's chest, covering him like an extra blanket. Will smiled and happily held him, kissing his head.

"Jem?"

"Hmm?"

"Don't be such a tease in the future."

Jem tipped his face up and smiled, eyes twinkling. "Given how this ended, I'm going to be much more tempted to do it again."

Will laughed. "If you wanted to get me in bed, you could've just asked."

Jem kissed his nose. "Ah, but what fun is that?"

Will just shook his head and pulled the blanket up over their shoulders, tangling their legs and resting his forehead against Jem's.

If it ended like this... well, Will supposed he could endure the teasing.
