BL Lemons and Fluff!

Marshall Lee X Prince Gumball

For Science

"Hold still."

"That'd be easier if you weren't poking at me." Marshall pointed out.

He was currently sitting atop a medical table, looking down at the Bubblegum Prince as medical equipment was attached to him. He tapped his fingers rhythmically against the table, his nails clicking faintly against the metal. "I don't see why you're so worked up over this."

"How can I not be?! I'm a man of science, after all!" Gumball said, glancing up at Marshall with a serious expression. "Now, tell me if you feel anything. Okay?"
Marshall hummed and nodded, a bit bored.

Science ran on a wheel attached to the devices he was hooked up to, but nothing seemed to be happening. Gumball watched him intently, looking up into his eyes. Marshall didn't see the point in all of this... But damn if he didn't enjoy the attention.

He jolted slightly at a tiny shock against his skin, glancing down at one of the wires stuck to his skin. Gumball leaned in a bit, his breath catching in excitement. "Is something happening?! Do you feel anything?!"

Gumball's hand was warm against Marshall's bare chest, and the vampire's eyes widened slightly as he felt the Prince's breath against his skin. He looked down at Gumball, a blush rising to his cheeks.
After a moment, it seemed as if Gumball could sense his stare, and when he looked up at Marshall he blinked.
"Oh! Hold that pose!" He shouted, leaning in and pressing his ear against Marshall's chest.

Marshall looked down at him, eyes still wide. "Wh-what are you doing?"

Gumball frowned slightly, furrowing his eyebrows. "I'm listening for a heartbeat, of course."
"You know I don't got one of those, Gummybear." Marshall said. His attempt at teasing fell flat, and Gumball looked up at him sympathetically.

"Marshall... Is this making you uncomfortable?" Gumball asked, placing a hand on Marshall's shoulder. He squeezed slightly, leaning in a bit. "I only ran this experiment to see if... Well, you obviously have blood flow, you know? Otherwise, you wouldn't be able to blush."

"Oh." Marshall hummed, looking down into Gumball's eyes. His blank, unhappy expression softened, and he smirked slightly. "Gumball. I think I'm feeling something."
"Y-yes? What?" The Prince asked, and Marshall leaned in a bit. He made as if to whisper in Gumball's ear, then burped. Gumball pushed him clean off of the table, glaring and backing up.

"Marshall!"

The vampire king couldn't help but laugh, looking up from the floor as Gumball rounded the table. The Prince huffed. "That was not funny."

"Yeah, yeah." Marshall chuckled, standing and pulling the little suction cups off of his arms and chest. He ran his hands through his hair, tilting his head back and letting out a sigh. "Man, I'm starving. Let's go grab a bite to eat?"
"Hold on. I have to clean up." Gumball said, waving Marshall away as the vampire followed him around the room.

"Hey, c'mon! If you don't hurry then- hrk!" Marshall grabbed at his throat, his eyes widening and fangs elongating.
"Marshall?!" Gumball stepped toward him, then gasped as Marshall wrapped his arms around him, his head tilting slightly as he blushed.

"I'm gonna go crazy. I'm gonna drink until there's no colour left in that pretty face." Marshall muttered, and Gumball shivered slightly at the words. The vampire chuckled, whispering darkly against the Prince's neck. "Oh, you like that?"

Marshall grinned and kissed a trail of faint kisses up and down Gumball's neck, then latched his lips onto the juncture of his neck and shoulder and sucked harshly.
"A-ah, Marshall, what are you-?!"
Marshall left a trail of stark white patches against Gumball's otherwise bright pink skin, but the deliberate and languid way he went about it made it obvious that he'd only been pretending to be in his feral starved state.

"Marshall, we have to get back. Butterscotch Butler is expecting me in my usual spot for teatime." Gumball muttered, closing his eyes lightly despite his words.
"And?" Marshall asked, grinning widely and looking up at Gumball from his position in the crook of his neck. "I thought you wanted to do some science? My body can do other blood related things too, you know."

That got Prince Gumball's attention immediately. He hummed softly, running a hand lightly down Marshall's side. "Please demonstrate, then."
