A/N: I was embarrassed about how rarely I publish these days, and I've been reading a LOT of Edward/Harry, Jacob/Harry and Edward/Jacob, and this plot bunny just wouldn't die.

Disclaimer: the standard one about how I own neither Harry Potter nor Twilight, etc. etc., not making any money, please don't sue. Also, everything I know about Twilight I've learned from the internet; I've neither read the books nor seen any of the movies. Seriously. This is what comes from too much slash.

Together in the Twilight

When people see the Cullen-Blacks, they often wonder 'who's the top?'. They see Jacob's tall, massively muscular body, and how he towers over the shorter, slimmer, younger-appearing Edward, so their first thought is 'well, of course, the big one tops, and the little one bottoms'. Then, if they're lucky, they get to know the couple a bit better.

Of two, Edward has the older soul. He's calm, reserved, thoughtful, and, well, a bit Edwardian (in the historic-era sense, please pardon the bad pun); he is obviously the mature adult in the relationship. In contrast, Jacob is loud, boisterous, impulsive, and very touchy-feely. He's just as likely to grab Edward and hug him in public—and kiss him, if Edward wiggles too much, just to embarrass him more—as he is to laugh too loudly or blurt out some borderline inappropriate comment, "just because". And, as people realize this, they begin to believe that Jacob is the bottom of the pair. More than that, they come to see Jacob Black as the stereotypical 'big butch power bottom'. That the stereotype exists tell you how many of them are out there, and Jacob like to play into it. Then, there's Edward and his behavior. 'Oh, of course,' they think, 'Edward is much too controlling to ever be anything but the top in that relationship'. So, most of them go on, convinced in their hearts and minds that they know exactly what happens in the Cullen-Black bedroom.

They couldn't be more wrong.

Oh, it didn't start out that way. It's debatable as to which came first, Edward's realization that Jacob was his soulmate or Jacob's imprinting on Edward. Carlisle's theory is that both things happened at roughly the same time. He bases this theory on the sudden explosion between the two that just happened one day; anger and animosity that dwarfed everything that had come before. Since both of them worked so hard at fighting what they were feeling, it was a rocky few weeks. When the two of them finally gave in to the inevitable, their relationship began to grow and develop...and both pack and coven sighed with relief.

Jacob bottomed first, at his own insistence. For weeks, that was their pattern: Edward would go down on Jacob, and even swallow (finding out that 'feeding' from Jacob was better than any cougar or grizzly bear, and left him much more satisfied), and Jacob would eagerly do the same before begging Edward to take him.

Not surprisingly, Jacob wasn't content to let this continue forever. Gentle hints became caresses to hidden areas, followed by kisses, then fingers...and then, one memorable night, Edward looked into his lover's eyes, let go of his fear, and rolled over.

What happened next changed both of their lives forever.

Jacob took his time, preparing Edward until the vampire was writhing and begging beneath him. Then, ever so slowly, the young shifter pressed himself into the cool cavern of his lover's body, his own elevated body heat warming Edward in ways that a century of existence had never prepared him for, the sensation growing and growing until at long last, Jacob was buried full-length in Edward's trembling frame.

Jacob didn't move for several long minutes, savoring what he was feeling while Edward adjusted to his considerable length and girth. Then, the young Quileute moved...and for Edward Cullen, the world shifted on its axis.

Jacob's first pull back brushed against Edward's prostate, causing the vampire to jerk in reaction. Then, as Jacob powered forward once more, Edward's new position made Jacob's entire length saw across the tender gland.

The sensations made the reserved, quiet vampire scream in ecstasy, as Edward Cullen discovered his most favorite thing in the universe: getting fucked by Jacob Black.

It wasn't long before even Jacob's enhanced endurance and stamina was being put to the test. Naturally, the coven and the pack being just who and what they were, it became no great secret, either.

Emmett took great joy, seconded by Paul and Quil, in referring to Edward as 'Miss Helium Heels'...but that didn't last long, since Edward's reaction was only to blush a bit, then smirk.

Jacob, of course, told them all it was none of their damned business. Then, he'd smirk, too. After all, he'd been the one that created that particular monster; he and no one else.

The truth be known, both young men enjoy doing pretty much everything to, with and for the other. They are both dominant personalities; neither of them is submissive enough to be a pure bottom. They switch positions like a tripping breaker. But, if they have a preference in the bedroom...and the living room...and the kitchen...and on the back deck...and in the woods...and while swimming...and in the backseat of their cars...and pretty much anywhere else the mood strikes them...Edward's ankles will be somewhere in the vicinity of Jacob's ears, while Jacob warms Edward's cold heart as only he can.

And the kissing is pretty hot, too.

A/N: for abby ebon, whose output astounds me. For WickedSlashAngel, who really is one. For Suiyou and the absolute best Yakuza!Harry fic ever. For harboringsighs, and a great line about switching from The Function to Breathe (chapter 6), without the straight bottom pun. For athenakitty: yes, Kreacher will get a sparky maker. And for all of you who read and review. And never tell me when all of these competitions are until AFTER I can't enter... For all of you who have me on 'Author Alert', and aren't just following Vale of Destiny. For the reader (whose review I can't find to credit) who said I wrote the best 'hot steamy man sex' they'd ever read.

But really and especially, for all of those of you who keep writing these most excellent fics. I'd much rather read your good stuff than write my own stuff. Hope you enjoy!
