EDIT: The... OVA... it... converted me... orz
Still took for-freakin'-ever to write, though!

"Ah!" gasped Grell against William's mouth, submitting to the kiss eagerly. The dark haired man forced his lips apart with his tongue, ravishing his mouth, disregarding the slight nicks he received from Grell's sharp teeth.

While Grell had enjoyed 'taking charge' of the situation before, the way he was being dominated now was far more enjoyable. The pain of the sharp angle he was forced into and the pens digging into his back only intensified the pleasure. As much as he'd complain about being 'abused,' the redhead reveled in it.

William smirked, well, as much as he was able to with his tongue near down Grell's throat. He was well aware of his colleague's masochistic tendencies and fully intended to exploit them. Wrapping one hand around both of Grell's delicate wrists, he ran the other down the scarlet shinigami's body. Grell shivered delightfully, sending shivers through Will as well.

Buttons, buttons, buttons... good gods, why did Grell wear so many layers of clothing? And ones that were so blatantly against regulation? With a bit of a growl, he grew impatient and resorted to simply yanking at them.

"Ah, Wi~ill!" Grell whined, "Not my good clothes!"

"Shut up. Or I'll stop."

The threat caused Grell to close his mouth with an audible click. He'd only wanted this for about a hundred years. This was not the time to push his luck.

Jacket, vest, ribbon, shirt, all pulled off – some buttons tearing in the process – and tossed aside.

William stopped. "Grell," he began, and cleared his throat, "Are you wearing a ladies chemise?"

"Why do you even bother to ask?"

"... Indeed."

Grell sighed dramatically. "Really Will? Is it that off-putting? Just get rid of it, then!"

"I was actually thinking... ah, it's not important," William muttered, and promptly removed the lacy garment.

With his arms stretched above his head and back flat against the desk, Grell's delicate physique appeared even more sylphlike, his ribs standing out against the flat plane of his stomach. Where did his strength come from, William pondered momentarily. This willowy body looked like it belonged draped in silks lounging in some salon, not running across the roofs of London dragging a deathscythe most reapers wouldn't dare touch, let alone swing about as if it were nothing more than a stick.

"Will?" Grell asked with some annoyance.

William realized he had stopped all action and was simply staring. After shaking his head to banish his musings, he began placing feather-light kisses on Grell's collarbone and shoulders.

Grell sighed happily, having worried that William lost interest in their activities. Trailing his mouth lower, the dark-haired man discovered he could not reach farther while still pinning Grell's arms. Moving his hands to hold the redhead's shoulders instead, he continued the kisses onto that temptingly taut stomach. Grell responded with a shiver and mewl. Why did he find sounds like that sexy? William couldn't even begin to imagine, but nonetheless, he did, and wanted very much to cause as many as he possibly could.

He slid his hands downward to pinch and tease the flamboyant reaper's nipples while he continued with open-mouthed kisses all over his abdomen. Grell arched into his touch with a moan.

So much for 'punishment', as it was obvious the redhead was in bliss. Ah well. He'd be getting unpaid overtime afterward. William smiled to himself as he imagined Grell's reaction to that!

Functionally short as William's nails were, they were enough to leave red lines down Grell's pale chest.

"Ahhhh~" The redhead writhed, enjoying the pleasure-pain sensations. His arms completely free, he twined his fingers through William's dark hair.

Immediately, the taller man caught his slender wrists and slammed them back down to the desk. Grell gasped at the suddenness. Taking advantage of his open mouth, William caught him in a fierce, bruising kiss. The scarlet shinigami's mew of delight was muffled between them.

The next moments were a confused tangle of limbs and clothing; the brunet shinigami stood with a slight huff of irritation and hastily rid himself of tie, jacket, and waistcoat.

The tie he wrapped around Grell's wrists and knotted neatly, as to free his hands for other activities whilst still keeping the redhead restrained. William noticed that Grell's slight pink blush increased as his hands were tied. He made a mental note of that.

With his usual brisk efficiency, the stern shinigami unbuttoned and removed his shirt. Grell's expression as he watched was one of pure desire. William allowed himself a slight smirk before he trailed a teasing hand down from the red reaper's shoulder, across his chest, caressed his stomach, and rested lightly upon the button of his trousers.

Grell made a strangled squeak noise and arched up against his hand, wanting him to undo it, or at least touch him more. Still smirking, the taller shinigami ran his finger lightly across the top of the waistband.

"W-will... please!" panted Grell, "I cannot stand this! I need you now!"

Need. Yes, the desperate look certainly was a needy one. William realized that causing such desire in the redhead was quite satisfactory. Briskly, he divested Grell of the trousers, pausing only when his foolish heels got in the way.

Unsurprisingly, the flamboyant reaper as also wearing ladies panties, a red lacy scrap of near nothingness that was completely pointless in covering him in the least.

"Why do you even bother?" William murmured, pulling at the elastic, and then yanking those off as well.

"They're decoration, not accoutrement," Grell replied with a sniff.

That high-nosed comment from such a position was... absolutely ridiculous. William couldn't hold back a slight chuckle. Grell shot him a glare, which only perpetuated it.

"Acting so high and mighty with your wrists tied, naked, on my desk. Honestly, Grell."

"'Honestly,' just cut the conversation and fuck me already!" the redhead snapped.

William was tempted for a moment to get dressed and walk out, just on principle. But his own desires were making themselves blatantly apparent and were not keen on allowing such a thing. A certain part of his body in particular was agreeing with Grell's statement wholeheartedly.

He placed two fingers against the slender shinigami's lips. "Suck," he commanded flatly. Ever obedient to such displays of dominance, Grell did so.

As much as he knew it was necessary, the 'preparation' was extremely unappealing to the dark-haired reaper, and got it over with as quickly as possible without causing his subordinate undue pain. Although, knowing Grell, he'd likely have enjoyed the pain anyway.

Unzipping his trousers, William placed his erection at the redhead's stretched entrance. Grell was near trembling with anticipation.

Without any warning, the taller man pushed himself all the way in and Grell cried out, his face flushing with rapture. The immediate tightness around William made him groan as well. The redhead displayed his experience with such matters by responding to every thrust with a shift of his hips that made him even tighter.

"Ahh~n Will! Harder, oh please... f-fuck m-me ha~arder!"

The stuttered, ecstatic moan was certainly enough encouragement for the usually expressionless reaper, who was now flushed and panting as he pounded his coworker against his desk. Any semblance of organization was now lost, as all the paperwork and pens were knocked to the floor with the force of their passionate activities.

Feeling his release nearing, William wrapped a hand around Grell's arousal and pumped in time with his thrusts.

"F-fuck! Will... ah! Y-yesss... nngggg!" The scarlet shinigami's exclamations only served to push William closer to orgasm, and he increased the pace of both his thrusts and the motion of his hand.

Nearly screaming William's name, Grell came hard over his hand and his own stomach. The dark-haired man bit his lip to keep his own cry of pleasure contained as he too released.

Leaning over the desk, he allowed a moment to catch his breath before pulling out and putting himself back to rights. Undoing his tie from Grell's wrists, he refastened it about his neck.

"Once you're dressed, you're to tidy my desk. And I want everything back exactly as it was. Oh, and I'm assigning you an hour of unpaid overtime every day this week."

Grell gaped at him.

"After you complete that hour... you're to report to my office for further... punishment."

A/N – Well that took far too long to write. Gods... -feels exhausted- I think I may be able to write these two from now on, though! :'D
