Notes

Written for fic_promptly. I was gonna upload this yesterday but uh, I had more trouble than expected trying to mount my computer screen to the wall. It's up now, at last! Also, moocifer week is coming up on bsky, so I was in a moo-d when writing this.

“Hey, Lulu, ya can shapeshift, right?”

Looking up from his workbench, Lucifer glanced over at Angel Dust, who was leaning in through the door to his tower.

If that wasn’t a question with an obvious answer, he didn’t know what was. Surely he’d seen him turn into several different animals in the fight against Adam.

“Yes, why?”

“I bought ya a cosplay, but it requires some… additions.”

“You’re going to have to be a bit more specific.”

 

Sauntering into the room, Angel hopped up on Lucifer’s workbench amidst all the ducks, dangling a plastic bag from his finger. As Lucifer peered into it, he squinted down at the contents before properly opening the bag.

He pulled the costume out of it.

“You want me to dress up as a cow?”

“Yeah.” Angel ran a claw down the center of Lucifer’s chest, hooking a finger into the hemline of his trousers to pull him closer. “I’m gonna milk ya dry.”

“I don’t think lactation’s really one of my kinks, but if you want to-”

“Nah, I was thinkin’ of milkin’ somethin’ else.”

Lucifer’s brows furrowed. “Then what would you… oh! You’re talking about my dick!”

 

Angel couldn’t help but laugh at Lucifer’s loud realisation. “That’s exactly what I’m talkin’ about. So, up to it?”

Lucifer’s cheeks flushed, before he held the costume to his chest. “I might be.”

“Perfect.”

 

Lucifer watched as Angel crossed his legs, leaning back on his upper set of arms. For a moment, Lucifer just stared at him in confusion, before another realisation hit him.

“Oh, you mean right now?”

“Why, got somewhere better to be?”

“Not really, no.”

Lucifer pursed his lips, eyes meeting Angel’s. “I’ll be right back.”

“Aw, not gonna change in front of me?”

“I’m, uh, more used to changing my clothes with magic, I feel so… strange changing like a regular person in front of others.”

“A lotta people feel like that, sweetcheeks. But you go change in the bathroom if ya wanna.”

“Okay.” Lucifer’s hand paused on the door handle to his bathroom for a moment. “I’ll, I’ll be right back,” he repeated once more, before letting the door slide closed behind him.

 

Staring down at the costume, he considered the parts. It had come with a tail and a headband with horns and ears, but since Angel had asked about shapeshifting, he assumed he should do that instead. He put them to the side.

The rest of the costume didn’t look like it’d cover much. It was practically a bikini, but with some extra details added, ribbons, bows and straps. Looked kind of cute though, he could see why Angel wanted him to wear it.

 

Letting his clothes rest on top of his largely unused hamper (why use it when you can clean your clothes instantly with magic?), he started to put everything on. After fastening the garters to the top of the socks, he let a shower of golden sparkles wash over his body, adding the details he knew Angel had been talking about earlier.

He could feel the tail push his underwear down, felt the heavy horns on either side of his head. His ears shifted curiously as he turned around this way and that in front of the mirror.

He felt a little exposed, but yeah, he looked kind of cute. But something was still missing.

 

Pulling at the front of the top, he chewed on the inside of his cheek in consideration.

“Hey, Angel?”

“Yeah?”

“With or without breasts? And how many?”

He could hear Angel’s laugh from the other side of the room through the closed door. “I didn’t even remember the four boobs part. Yeah, sure, extra nipples could be fun. Maybe keep’em flat though. Do whatever ya want with the top ones.”

For a moment he was about to correct Angel, tell him that they were called udders, not boobs, but in this case, they would be, so he supposed it was fine.

Humming to himself, he let himself be enveloped by his magic once more, and when he met his own reflection again, he felt much more satisfied with the way the costume looked on him.

 

As he stepped out of the bathroom, he heard Angel’s whistle.

“Ya look real fuckin’ cute, sweetcheeks. And your boobs aren’t bigger than mine.”

Lucifer laughed, stepping up to his workbench to stand in between Angel’s legs, hands resting on his thighs as he leaned forward, head tilted up by Angel’s hands on his cheeks.

“I thought you said they weren’t boobs.”

“Only when I want’em to be,” Angel said with a wide grin. His fingers ran down Lucifer’s ears, his second set of hands running down his spine, down to the base of his tail. “Ya look good like this. Makes me wanna slam ya against the bench and fuck ya till ya pass out.”

The smile on Lucifer’s lips grew, and he could feel his cock twitch as Angel started to stroke the fur at the base of his tail with his claws.

“So why don’t you?”

“Mm, said I was gonna milk ya first, didn’t I?”

“You did. I guess we should get on that, then.”

“Uh-huh.”

 

He let out a startled laugh as he was lifted off the floor, up into Angel’s lap. Angel’s thighs were warm beneath his, his warmth spreading throughout his always too-cold body.

“Get me a milk bottle, will ya, sweetcheeks?”

Lucifer laughed. “Oh, you were serious, were you?”

“Deadly.” Angel hooked a finger into Lucifer’s collar, making the bell rattle as it moved. He pulled, Lucifer standing up on his knees, chest flush against Angel’s. Angel bent down, pressing a kiss to his lips.

It was slow, Angel’s mouth warm, his tongue pushing inside his mouth as Lucifer invited it in. His hips bucked as he felt Angel’s fingers cup his cock through his underwear, and when the kiss ended, Angel’s grin was sharp.

“So, ya gonna get me that bottle?”

“Oh, uh, yeah. Of course.” As soon as Angel had kissed him, the thought had vanished right out of his head.

 

In a poof of sparkles, he let a bottle appear in his hand. Angel plucked it out of it as he pressed another kiss to his lips.

“Thanks, baby.”

 

Lucifer bit his lip as Angel’s hand slid into his underwear, his fingers wrapping around his cock. He stifled a groan as Angel’s thumb pressed against the slit at the head.

Angel leaned forward, the air as he spoke hot against his ear. “I’m gonna make ya cum till ya fill the bottle aaaaall the way to the top.”

Lucifer felt his excitement build, his hips bucking as Angel’s hand started to move. His fingers dug into Angel’s shoulders, holding on tight so as not to lose his balance.

He met Angel’s eye, a grin spreading on his face.

“I’m looking forward to it.”
