Jack was sitting in the cave near his pond that he called home whenever he wasn't bunking at North's or out bringing snow to various parts of the world. He liked the little nook, as sparsely decorated as it was with a bed a chair and a table, it was his place to get away from everything and he liked it like that. He had always been a solitary spirit, even after children started to believe in him and he became a guardian he still preferred the company of his thought and the wind to that of others…with one notable exception. It had been over a month since his last tryst with Aster, and as much as it riled him to admit it, he was missing the Pooka. Easter had just passed, so of course he was busy with all that, but it was late Friday night, he should have had time at least one night right? These thoughts led Jack down same usual path, namely wondering why it bothered him in the first place; it wasn't like they were together, it was just sex, mutual pleasure… right?

Jack's thoughts were interrupted by the sight he'd been hopping to see for the last week, a single egg popping out of a hole in the ground and scurrying up to him. The egg was painted in the pattern of a Jack of Spades, it was Aster's way of calling him to the warren and the Pooka found the design downright hilarious, a reference to their first time together. Jack's heart did a little flip as he picked up the egg, he filed that away under 'figure out later' and walked out of his cave, launching himself into the air and urging the wind to carry him faster as he flew off toward Aster's warren. He arrived just under twenty minutes later, landing silently outside the burrow Aster called home. He opened the door to find the lights in the main room of the burrow were out, a light came through the partially open door down the hall that Jack knew was Aster's bathroom. Jack made his way swiftly through the burrow, he knew its layout well enough by now that the dark was no issue, shedding clothes as he went.

He had only just entered the room when he was swept into a furry embrace; strong paws pulled him against a soft chest, warm lips pressed hungrily against his own. Jack sighed into the kiss, a tension he had not realized he'd been carrying draining from him as Aster's tongue forced itself into his mouth, the slick appendage dancing with his own as it explored his mouth. Jack melted into the kiss wrapping his arms around Aster' neck and his legs around Aster's waist, both of them moaning as their hard-ons rubbed together. Pulling away from the kiss Jack said breathlessly "Someone miss me?" In response Aster growled and pulled Jack back into the kiss, grinding his hips against Jack's as he did so.

Aster carried Jack to the bed and deposited the winter spirit on the soft blankets roughly. Jack bounced twice before settling on to his hands and knees; he was slightly surprised by the Pooka's haste, then again he himself felt the same hungry desire he'd felt in the kiss and in the way Aster held him, and something else too... He didn't have much time to think about that though as all thoughts were driven from his mind by feel of Aster's tongue at his entrance. Jack moaned and shivered in pleasure as Aster's tongue slid around the ring of his entrance before slipping inside briefly. Aster continued to prep the winter spirit for another minute before he straightened and moved forward, stopping in a kneeling position behind Jack.

Jack gasped at the initial pain as Aster pushed into him, he was far more used to it by now but it had been over a month since the last time and the Pooka was still huge. He let out a shaky breath as Aster buried himself completely, Jack felt incredibly full, Aster's member stretching him to his limits. He felt Aster stop, waiting. Jack took a deep breath and nodded, letting it out in a hiss as Aster slowly slid out and then back in, his strokes slow and deliberate. After a minute of that the pain had mostly gone, replaced familiar and enjoyable sensation of being filled; Jack nodded again. Aster started to pick up speed his strokes coming faster and faster as Jack whimpered and moaned, Aster himself starting to breathe harder.

Jack threw his head back and shouted as Aster found that place inside him that set every nerve in his body on fire "Right there, right there Bunny, oh yes!" Aster started going harder and faster, aiming for that spot with each thrust; he lowered himself down so he was parallel to jack. His furry chest pressed against the winter spirit's back and one arm wrapped around Jack's chest. Jack was moaning with each thrust now as Aster slammed into that spot at an inhuman speed, each collision sending a little shudder through his body. He could feel Aster getting close above him, his thrusts becoming more sporadic as he approached his climax. Jack moaned loudly the sound more high pitched then he would have preferred, not that he cared much at the moment as Aster's paw wrapped around his throbbing member and started pumping furiously.

Aster let out a deep growling moan as, with one last thrust, he emptied himself in Jack, thrusting lightly as he did so; each motion of his hips sending another spurt into the winter spirit. The feeling of being filled by the Pooka and the continued attention to his shaft were too much for Jack and he came hard, spraying all over the blankets and Aster's paw, his entire body spasming with each shot. Panting heavily Aster let himself fall to the side, pulling Jack with him. They both laid there panting, Jack's back against Aster's chest and one of the Pooka's arms still draped around Jack's chest. After a couple minutes Jack inched out from under Aster's arm, wincing slightly as Aster slid out of him with a wet 'pop', Aster shivering at the sensation, and made to get up.

Aster grabbed Jack's arm before quickly releasing it, his ears going back and a strange expression on his face he said "Ya know Frostbite…its late…you can stay…ya know, if you wanna."

Jack looked at him for a second, trying to judge what his expression meant. He seemed serious, and Jack was completely exhausted. "Alright." He said with a grin, settling back into the back, under the blankets this time.

Aster grunted in response and rolled over, the even sound of his breathing filled the room a moment later punctuated by the occasional low snore. Jack laid there for a few minutes longer, trying to make sense of many things and failing miserably. Finally he rolled over so his back was to Aster and drifted to sleep in the unusually warm, and very comfortable, bed.
