PLEASE READ FIRST; I will forewarn you this one has some rapey themes, Remus does hold Sirius down during this, but nothing explicitly happens, it stops the moment it heads that direction when it's no longer fun for Sirius, but I would never wish any triggers on anybody with that kind of surprise. It's entirely in Sirius' POV.

As usual, the italics are the scene before for context in the fic, but if you just want to read the sexy stuff it's in normal font.

Sirius started humming to himself as he circled the bike, running his hands over the engine and tapping his wand on the tires, eying every loose bolt and exposed wire with such a deep desire to know more about it Remus couldn't drag his eyes away as he felt the others leave. They didn't have to hide out anymore, and that was weirdly freeing, but he was pretty sure this would have happened regardless. Prongs had only been in it for the fun of the ride and would leave this in Padfoot's capable hands as he kept interacting with the others, but he could sit here and watch Sirius for hours get invested in this.

Padfoot began picking up scattered tools and arranging them, his wandering eyes traveling the dusty ground to make sure he didn't miss any, and seemed surprised to see him still in place, just leaning against the wall and watching him with a fond smile. "You weren't actually mad before, were you? About me kissing you in front of everybody?" He sounded more concerned than actually curious like he seemed to want to as he forced a smile at the end.

"No," he said quickly as he shifted guiltily in place for Sirius thinking otherwise. He would have thought kissing him in the hospital wing had cured Sirius of that lie. "More surprised than anything, you've never done anything like that with one of your hookups before. I didn't realize there would be a change when you committed, but no, didn't really bother me."

To his horror, Sirius made that horrendous face again, the one he had back when he'd first confessed his crush. Remus went painfully stiff and wondered again if Sirius had even fully accepted himself there was a difference.

Sirius shook himself though and said quickly, "okay, just making sure."

He kept himself in place and would not let him deflect, or this would get far worse very fast. "Sirius, what was that?"

"What?" He said sincerely enough, and Remus pressed his lips together as he eyed him. Sirius kept meeting his eyes and fidgeting with his hands, he kept shifting in place like he wanted to go back to the bike already now that he was sure nothing was really wrong, perfectly normal.

He started fidgeting with the sleeve of his robes and tried for a moment to think how to ask, before as usual just letting his mouth run, it often got the best results with him, even if he did acknowledge himself a hypocrite for scolding Sirius for doing the same. At least he kept his thoughts crowd friendly. "I, um, I'm just worried you haven't quite realized yet that, I'm going to run out of ways to keep you, ah, newly entertained in bed one day. Please don't feel the need to pretend otherwise if you, still think, you want something else. The sooner you rip that band aid off, the better."

There was the briefest pause as what he said really sunk in.

"There, that face!" Remus said quickly as Sirius tried to smooth his expression back out. "Tell me what you were thinking, please?"

He bit his lip first with something that could not possibly, actually be guilt as he sighed and sunk down onto the bike and said, "that, I'd live like a monk first because I wanted to be there for you if you really wanted me in that way."

He walked carefully forward, watching Sirius like the thinnest of smoke that would vanish the moment he looked away as he sat down beside him, head spinning too much to not do so. "Don't be so dramatic, at least try vanilla first."

Sirius laughed, thankfully. There really was no better sound on Earth to him. Sirius reached up and brushed under the edges of his eyes, though the self inflicted scratches were long healed as he watched him carefully as he explained, "I, just keep thinking, Prongs has always been an idiot around Evans, but he, I don't know, always kept hoping she'd like him regardless, but I never got why. She used to be so snobby, and I don't know, we all noticed she was easing up on James and started acting much less bratty for it. And how Frank's been so, well, less of a git because of Alice. I'm pretty damn confident of that anyways, she definitely never had a problem with you when he did. So I, kept asking myself, shit, I don't know, would it, would I-"

He stopped and made that face again, and Remus finally realized he was trying to put into words what he thought of his own past behavior towards him! "Bloody hell," was all he had in himself to whisper for several long moments as he caught Sirius' hand and just held it. "I, never asked, or wanted you to-"

Sirius looked extremely sheepish for the admittance now, even more wrongfooted like he'd been caught doing something of the greatest of embarrassment. "I know you didn't," he shrugged, but his face kept getting more red. "I just, I was so pissed at myself you hid your crush from me! It was the only thing I could think of, agreeing to give dating you a shot, I hoped you'd never want to lie like that again if I, um, gave you a reason not to, so I kept telling myself I'd do better if you were my-"

He was stopped abruptly by Remus practically attacking him he locked their lips together so fiercely.* 

Moony had him pressed down into the handlebars in moments, and it was a good thing this was still broken as he felt several buttons deplete, but the bike only vibrated around them which only riled Remus up more as he started groaning, his teeth already dragging along his lip.

It started shaking dangerously beneath them, the engine making a loud whine of protest as he eagerly snogged him back, but Sirius was apparently far more concerned about it exploding around them than Remus for once. Moony had one wrist still pinned in his hand, the other was crammed between his boyfriend and the bike and he barely had the mobility to move, so he reached up to put his hand on his throat, fingers digging in firmly as he tried easing him back with a breathy, "this thing's going to go off before I do if you don't let me up."

Remus huffed and still didn't entirely release him as he helped him sit up, his hands roughly trying to coax Sirius to turn and sit on the bike proper as he swung his leg over with a teasing, "thought you were going to give me a ride?"

Now that he was off the multicolored dash, the bike began to quiet but still shook enough it was pretty invigorating and his groin was pumping far too hard to pretend to ignore the insinuation as he threw himself down in front of him and leaned his head back to tease, "isn't that your job?" He paused though, even as Remus started eagerly brushing his hair aside and asked in some concern, "did you mean that? I haven't offered-" it was sort of his point, he'd been pretty damn selfish constantly flaunting his many hook ups and never even properly asked Remus what he did want out of this, it was no wonder Moony felt the need to keep his mouth shut for so long!

"Maybe later," and his voice was just too heavy to be anything but turned on right now as he eagerly took over, his hand at once cupping Sirius while the other gripped his waist, lips pressing roughly to his jugular.

He hummed with pleasure and hooked his hands onto Moony's knees encouraging him to really go, but Remus seemed content this way now he had Sirius. His hand was tightening painfully so that Sirius fully felt it through his pants, fighting back the urge to rip them off any second, his lips were growing rougher by the second upon his neck, but the bike was still the only true movement.

Sirius' own hands couldn't stay inactive, one pressed over Remus' and he began moving beneath them, his other reaching up and hooking onto Remus's neck and starting to pant a bit at the hard nudge he could feel building behind him.

Remus was being weirdly unhelpful though, holding him down tighter as Sirius finally got the button of his own pants undone, but couldn't go farther as he was finally grinded from behind but Remus' hand went back to gripping rather than any movement. Sirius was starting to feel weak at the knees, even more sweat beading along the back of his neck now which was only encouraging his lover, Sirius could feel teeth there now and his tongue working furiously against his pulse.

Sirius' hands tried to work from behind him, to help Moony along but the act was impossible, his grips were turning bruising on all three, leaving Sirius' hands a worthless mess as he clung again to Remus' wrist instead, the other spasming uselessly on his knee once more no matter his desire to try and relieve Remus of the same.

He didn't seem that concerned, nudging harder and harder along Sirius' backside while grinding against him as the bike amplified everything, soft little growls starting to erupt from his throat as he kept up the friction when Sirius couldn't properly settle, the grip on his dick was starting to hurt most of all for not being able to touch himself as the heavy rocking continued not nearly as much as he wanted. Remus should well know this wasn't his preference, what was he playing at? 

Moony always had a tendency to go for the neck. He'd gained more hickeys from being with Remus than all of his past put together and it had never bothered him a lick, usually it was pretty hot. Now, even in the haze of bliss and his blood pumping through his ears as well as everywhere else, he may have to reconsider for this one, he could already feel through the deep pleasure what this was going to do to him.

It only belatedly occurred to him to tell Remus to get off, and he started trying to figure out how to do that in his head nicely considering the last time he'd spoken about this Moony had definitely withdrawn in himself a lot, but that was becoming harder by the second to keep any organized thought together as he actually started to try pulling his wrist away.

The bike's flimsy kickstand was not going to last, this was not as fun anymore as he groaned heavily now, intentionally jerking under him uncomfortably. Remus wasn't letting him though, and anger was rising fast as he twisted impatiently! The movements were timed with the still saddled boy behind him, keeping him painfully in place, who was using all teeth on that same spot along his still soft flesh where just as much blood seemed to be pooling as his groins-

Sirius gasped and fell to the ground as he was released, he almost landed wrong but thankfully saved himself at the last second and did not actually hit his throbbing area on anything below. His hand still hovered protectively as he glared at what had been holding him up, but Remus was already running out the door.
