“Fuck,” Lucifer groaned, pressing into Alastor slowly, unable to tear his eyes away from the sight. Despite all the prep, the demon beneath him was still tight and it was slow-going.
“S-Stop. I need- stop. Stop!” It took a fraction of a second for Lucifer to register the words, but when he did, he froze completely. Alastor had his eyes screwed shut, his hands fisted in the sheets below him hard enough to rip holes in the fabric, his voice uncharacteristically cracked and slightly panicked, static buzzing in the air around them.
“Okay,” Lucifer said immediately, “Okay, we’re stopped.” His chest was heaving a bit as he panted, but he didn’t move an inch. Alastor’s eyes were looking anywhere but at him, a grimacing smile stretching his lips far too wide. “I’m gonna ask some questions. I just need a nod or a shake, okay?”
Alastor gave a single sharp nod, still averting his eyes. His ears were pinned flat to his head, betraying his embarrassment and displeasure at being coddled. Yet, he didn’t try again to speak.
“Are you hurt? Am I hurting you?” Lucifer asked. The last thing he wanted was for Alastor to be in pain.
A shake.
“Do you want me to pull out?” he prompted. It would make things a little less awkward at least, but Lucifer would prefer to have permission before moving forward or backward.
A moment of consideration and then a shake. No moving then.
“Are you overwhelmed?” Lucifer suggested. That was the most logical conclusion. It was typically the reason that Alastor put a stop to any kind of touching.
A very long moment and then a nod.
“Are you overwhelmed because the touching is bad?” Lucifer asked, the question was a bit hesitant as he worried about the answer.
A shake.
“Are you overwhelmed because the touching is good?” Lucifer asked. This time, his tone was a little more hopeful and more than a little relieved. At least it wasn’t bad.
Another shake.
“Because the touching is new?” Lucifer tried, running out of options.
A slow, careful nod.
That made sense. They’d never done this before. Fingers, yes. Even Lucifer’s tongue once, but never this. It was new, it was different, and Alastor was processing. A similar thing happened with most of the new things they tried, but this was the first time Alastor had seemed so urgent rather than just uncertain or considering.
“Do you just want a minute to decide how you feel?” Lucifer questioned.
A jerky nod.
Lucifer was quiet for a few moments, wanting to give Alastor space. At the same time, he didn’t just want to sit there uselessly with his dick half in his partner. “Can I hold your hand?” he asked.
In place of a nod, Alastor stiffly unclenched one hand from the sheets and turned it so that his palm was facing upward. Rather fluent in Radio Demon Body Language, Lucifer knew this was as close to a ‘yes’ as he was going to get. So, he reached out and laced their fingers together, holding Alastor’s hand in a steady grip and letting his thumb rub soothingly against the other’s warm skin.
It could have been hours or minutes of them just frozen in that position. Lucifer had let his eyes drift closed, willing to wait days if that was what it took for Alastor to find his comfort level. He supposed it couldn’t have been all that long though, since he was still hard.
“Keep going.” The words were barely more than a murmur and Lucifer almost missed them completely. He was thankful that he hadn’t. It was difficult to get Alastor to talk at all when things like this happened, let alone get him to repeat himself.
Slowly, so slowly, Lucifer started pushing forward again. He never let go of Alastor’s hand and this time, he kept his gaze trained on the demon’s face. He went one torturous inch at a time until he was fully seated inside. All the while, Alastor’s grip on his hand had been tightening, but he didn’t request another full stop.
Lucifer stopped anyway. He waited just as they were until Alastor’s grip on him loosened to something more regular, more comfortable.
“Go?” Lucifer asked, needing the confirmation before doing so.
Alastor nodded. Lucifer could practically feel the temptation the demon had to roll his eyes, but he evidently managed to keep a lid on the urge. As if it was totally unreasonable for him to be asking something like that.
Despite the permission, Lucifer didn’t just go for it. He started with gentle rocks of his hips, not even really pulling out at all before pressing in again. When there was no negative reaction, he went a little further, moving back a small fraction before nudging himself back in. Again, nothing immediate that told him he needed to stop.
During all this, Alastor’s erection had flagged considerably, but not completely. Lucifer made no move to touch it. That was a firm boundary that had been set some time ago and he had no intention of crossing it now.
Lucifer’s thrusts gradually began to pick up in length, but he kept the pace slow and languid. He certainly wasn’t in any kind of a rush.
His attention didn’t start drifting, per say, but rather than being so hyper-focused on Alastor’s face, he let himself take in the rest of the demon’s body and back down where they were connected. That was why he missed the flush that was rising on Alastor’s face and the way his lips had parted.
“Nngh.”
Lucifer’s eyes snapped back up at the soft sound, so soft he could’ve imagined it. But no. Alastor’s cheeks were hot and he was breathing heavier, his cock showing renewed interest in the proceedings.
“Good?” Lucifer asked.
“Don’t be cocky,” Alastor snapped, a little too breathless to sting the way he probably wanted it to.
Lucifer smiled. He almost wanted to laugh, but he knew that would be taken the wrong way. He was just so glad that this hadn’t all ended in disaster.
“Can I kiss you?” he asked, just wanting to make sure. Alastor nodded.
It was a little awkward, because of their difference in stature, and he had to let go of Alastor’s hand, but Lucifer managed to press their lips together as he continued the movement of his hips.
It never became rough or desperate. Everything stayed soft and gentle, with perfect little noises getting coaxed out of Alastor more and more, matching with Lucifer’s low, pleased sounds of his own.
“Do you want to finish tonight?” Lucifer asked, panting slightly, knowing that he was getting close himself. Alastor shook his head.
Lucifer didn’t ask questions about that anymore. He just held the demon close, kissing him when he was able and rocking their bodies together until he came inside of Alastor with a soft gasp of the other’s name.
For a time, the only sound in the room was both of their labored breathing. After giving himself a few seconds, Lucifer pushed himself up a bit so that he could pull out.
“Wait.” Alastor was looking off to the side again, one hand having reached out to grip Lucifer’s bicep.
“Okay,” Lucifer agreed easily, not needing further explanation. Instead, he just settled himself back down. In fact, he settled even further down. He let his forehead rest against Alastor’s warm chest, feeling his thundering heartbeat under his skin. Alastor’s hand came up to card through Lucifer’s hair.
Lucifer very politely ignored the way it was trembling.
They stayed that way until they both went soft and Alastor finally acquiesced to having them change position. The two of them were clean with a wave of Lucifer’s hand and with another wave, they were tucked under the covers. Alastor had moved himself away a bit until the only parts of them that were touching were their newly entwined hands.
“Okay?” Lucifer asked quietly after some time had gone by.
“Yes,” Alastor said, his voice soft as a gentle melody began to play in the air around them.
“Ever again?” Lucifer asked with a bit of a smile. He could practically feel Alastor rolling his eyes.
“Perhaps someday,” the demon answered vaguely. For Alastor, that was practically a guaranteed promise. Lucifer couldn't stop the wide smile that spread across his face.
