"Ow. Ow!. Sirius!" Remus winced as the pain in his shoulders flared up again. He was spread-eagled on the bed, wrists and ankles secured to the four bedposts. Problem was, the bed was either too long, or the bits of rope Sirius had conjured were too short. "The idea is to get off, not stretch me five inches, yeah?"

"Sorry!" Sirius frowned down at the complicated knots at Remus wrists and reached out to tug experimentally at one.

"Ow! Fix it, Sirius!"

"I'm bloody well trying!"

"Well, you should've done it by hand rather than using a spell."

Scowling, Sirius flicked his wand. "How's that?"

Remus rolled his shoulders and heaved a sigh of relief. "Much better."

Sirius brightened noticeably. "Yeah? Brilliant." He waved his hand vaguely over Remus. "I'll guess I'll just...carry on then."

He bit the smooth skin of Remus' inner thigh as payback for snickering. He liked the reaction it got him so well that he bit the other one, relishing Remus' slow hiss. He could tell Remus liked it, too, because his cock began to lift and fill until it pointed up at his navel at twelve o'clock.

He shuffled down on his side so he could rest his head against Remus leg while giving him a thorough finger-fucking. A muttered spell coated his fingers with slippery gel, and he wasted no time in working a couple of fingers inside Remus' tight hole. The breathy little moans it forced out of Remus made Sirius hard in seconds flat, too.

By the time he had three fingers inside pumping deep and smoothly, Remus was pushing his hips up off the bed as much as his bonds would allow. Sirius withdrew his fingers, dancing them teasingly up Remus cock.

Remus snarled, jerking against the ropes tying him to the posts. Sirius could tell he was dying to reach down and pull himself off.

"Come on, Sirius. Fuck me."

"As if you're in any position to make demands."

"Sirius."

"Moony."

Sirius sat up, smirking down at his horny boyfriend. "You want my cock?"

Remus looked mutinous, but he jerked his head in a nod.

"Say it." Sirius' smile stretched wider, his fingertips now tapping against Remus' hole again.

"I want it," Remus bit out. "I want you to stick your big fucking cock up my arse right now, all right?"

"All you had to do was ask." Smirking again, Sirius moved up between Remus' spread legs and slid his hands under his thighs, raising his hips off the bed as much as the situation would allow. His smirk faltered, and his brow furrowed in concentration as he slid his own knees a little wider and tried to sink down toward the mattress and line his cock up with Remus' arse.

It didn't work.
