A/N: So this will basically be a series of one-shots within the same universe with the same theme. I will wrap them up with a tidy bow at the end, but they are all little snippets that can be read on their own.

Disclaimer: I don't own anything except for the citrus-y plot.

It was a bitterly cold Monday night and Jace and Clary were about halfway back to the institute, when Clary suggested stopping at a local coffee shop on the way. Jace was ready to refuse; after a particularly harrowing visit with Jocelyn and Luke, he had just about enough of this evening. He knew that Jocelyn loved her daughter more than anything, and she had even begun to warm up to him a bit, but it was still exhausting, feeling like you were watched with suspicion every time you're around someone. And though Luke tried to ease the tension, Jace always seemed to leave these visits wound up and rather cranky.

He definitely did not want to make any extra stops, but when he turned toward Clary and saw her tired expression and slightly pouting lip, the next thing he knew, he was nodding his head and they were lining up in the queue.

It was awfully cold outside and he supposed a hot tea wouldn't be the worst thing to have for the rest of the walk.

He quickly came back to regretting the decision when the young barista flashed a flirty smile at Clary, giving her a coffee at no charge. He was sure to charge Jace full price for the tea he ordered, and, in turn, Jace was sure to wrap an arm possessively around his blissfully oblivious girlfriend, pulling her into his side and kissing the top of her head as he sent a harsh glare toward the barista that had him retreating to the back room, allowing someone else to take over the register.

Warm drinks in hand, the pair headed back out of the coffee shop to walk the remaining few blocks home, Clary happily placing her mittened hand into Jace's, as to not get separated in the crowds that seemed ever-growing in New York this time of year. The snow that had begun to fall seemed to encourage people to crowd even closer together on the sidewalks, giving Jace the distinct feeling of a rather cold sardine.

Shortly after, Jace and Clary rushed into the Institute. The wind blew some snow into the foyer behind them as Jace hurried to close the door. He turned to see Clary with a wide smile on her face, her knitted cap tilted on her head with her curls cascading down her shoulders and back, wet with snow. With a raised eyebrow, and a small smile playing on his lips, he asked, "and what are you so smiley about?" as he took the empty cup from her hand, disposing of it along with his in the entryway receptacle.

"W-what's n-not to smile about?" she asked through chattering teeth, still grinning up at him through the incessant shivering of her body.

"Well, for starters, you seem to be turning into a human popsicle," Jace pointed out as he stepped closer to her, running his hands up and down her arms rapidly to try to infuse some heat into her.

Clary stepped even closer, wrapping her arms around his waist and looking up at him. "But I have you to warm me up," she responded much more steadily, the shivers subduing to a mild tremor every now and then.

"Is that why you keep me around?" Jace questioned, wrapping his arms around her in kind, and pulling her flush against his body. Well, as flush as he could get her through all her layers of winter wear.

"One of the reasons," she murmured, reaching a hand up to bring his head down toward her.

Jace paused just before their mouths touched, brushing her cold, red nose with his slightly warmer one. "So there's more?"

Clary simply hummed in agreement before tugging at his hair a bit more forcefully, bringing his lips down the final inch to finally meet hers. Jace was already rapidly warming up from the heat blasting through the Institute, but he quickly forgot all about the remaining cold as Clary's lips parted, allowing him to deepen the kiss. Jace's hand wandered to the edge of her coat, nimbly slipping under the multiple layers, allowing him to run gentle fingers up and down her back.

He heard her make a soft noise in the back of her throat, and he walked her back toward the elevator, deciding they needed to move this to more private quarters. When the doors finally opened, they stumbled in, the kiss turning needier as Jace blindly hit at the elevator buttons, unwilling to break the clash of tongues and lips and teeth that had his mind whirling.

He pushed Clary's large coat off her shoulders, letting it pool at their feet, her scarf and sweater were quick to follow. They had to break apart as the sweater came over her head, but Jace was not deterred, as he quickly set to work on her neck, determined to coax from her more of those soft moans she was clearly trying to hold back, telling from the way she was biting her bottom lip, hard.

When he gently sucked on the skin just below her ear, he was rewarded with what could only be described as a mewl, making him grin triumphantly against her skin.

Clary must have slipped her mittens off at some point, because Jace felt her small hands work at his belt and then the button and zipper of his jeans. She wasted no time, as she reached into his pants, pressing her hand firmly against him through the thin material, causing him to let out a deep, guttural moan.

Just then the elevator doors dinged open, and Jace hoisted Clary up, her legs wrapping around his waist, ready to move to the bedroom. What he failed to notice as his girlfriend had released her grip on him, only to grind her core against his erection when he lifted her, was the fact that there were two people waiting to get in the elevator.

"My eyes!" Simon cried out in a rather high-pitched voice that grated at Jace's ears.

Isabelle made a tsking sound. "For angels sake, can't you two get a room?" If Simon's rather high-pitched complaining didn't kill the mood, his sister's voice certainly did it for him, and Jace let out a frustrated sigh as Clary buried her red face in his shoulder, refusing to meet anyone's eyes.

Jace eyed his half naked girlfriend and his own unbuttoned pants. He wasn't particularly modest, but he was pretty sure if he put Clary down like this, his girlfriend might implode with embarrassment. He wasn't exactly fond of that idea, despite the fact that he was always tempted to see just how red her face could manage to get, if, by any chance, her hair had competition. "You'll have to catch the next one," he deadpanned as he hit the button for the elevator to take them back down, the doors closing in the Izzy and Simon's bemused faces.

Once they started to move, Jace gently set Clary down and went about putting himself away as she found her sweater and pulled it over her head. He had just assisted her in pulling her coat back over her shoulders as the elevator started to move upwards again.

He scooped up her scarf, mittens, and hat - though he wasn't entirely sure when the hat had come off her head, and grabbed her hand just as the doors dinged open again. Jace simply pulled Clary past an annoyed Isabelle and indignant Simon, muttering, "All yours," as he passed.
