“I wanna dirty you up, then clean you off so I can get you dirty all over again.”

Shifting in his lap, Jude pressed his core against Toni’s dicks, and they both groaned.

“I gotta go,” Jude said between rolls of his hips, “to class.”

“You can’t go to class. You’re terribly ill. I gotta keep you in bed and nurse you back to health. It’s gonna take all day.” Toni grabbed a fistful of Jude’s ass, grinding them harder together as pleasure zinged up his spine. “Yeah, like that, baby.”

With a moan, Jude flattened his hands on Toni’s chest and pushed him down, mouthing at his jaw. It would have been sexy if Toni didn’t have a rather inflexible fin on his spine.

“Fin,” he whimpered, and Jude sat up.

“Shit, sorry.”

“S’okay.” Toni tightened his hold on the human’s waist and spun them around until Jude was on his back. He settled between Jude’s spread legs, aligning them just right, and—

“Oh fuck,” Jude gasped, hands grasping at Toni’s hips. Then he was shoving up Toni’s shirt, and Toni was only too glad to be rid of it. “This can’t take long. I can’t skip class.”

“No pressure,” Toni grumbled as he tossed his shirt aside.

Jude’s hands were tentative as he dragged exploratory fingers over Toni’s chest and down his stomach. He traced the dark blue stripes and the places Toni’s bones pressed against skin. With them both shirtless, even Toni could see the difference in the placement of muscle and bone, but, like Toni, Jude seemed to like that they weren’t the same.

Blunt teeth digging into his bottom lip, Jude smoothed his palms up Toni’s torso until they rounded over his shoulders. His thumbs skimmed the skin under Toni’s lowest set of gills, and he met Toni’s gaze.

“Does this hurt?” he asked, thumbs rubbing again.

Toni shook his head. “I mean, don’t shove your fingers inside or anything.”

Jude grinned. “Wasn’t planning on it. I just don’t want to hurt you.”

“I ain’t that breakable, bitesize.” He leaned down and pressed his lips to Jude.

The human pulled away. “No kissing until you brush your teeth.”

“Picky, picky,” Toni mumbled against his jaw.

“Wait, do you breathe with both your nose and your gills?” Jude asked as Toni nibbled on his earlobe.

“Is this really what you wanna talk about right now?”

“Oh come on, can’t you multitask?” Jude grazed his teeth over the nape of Toni’s neck and snuck a hand between them, cupping the front of Toni’s pants.

“Fuck, not if you touch me like that.” Toni thrust into his hand.

“Try,” Jude teased, rubbing in a way that had Toni’s brain glitching.

“I, uh, can breathe with both, though they connect to different lungs,” Toni managed to ground out. “One set’s better for water. The other’s better for air.”

Jude stopped his ministrations. “You can breathe underwater?”

“I really feel like this conversation should be saved for another time, especially if we’re on the clock,” Toni practically growled.

“You’re a different species than me. Of course I’m curious how your body works!” The teeth on Toni’s shoulders bit harder, and Toni groaned. “Stop whining.”

“For fuck’s sake.” Toni lifted up, glaring down at the infuriating human. He pointed to his chest. “Two sets of lungs because my ancestors were water-based. Then we evolved, but we still like to swim.” Then he pointed to his gills. “For breathing underwater, though I can use them in air. It just feels very dry and itchy and uncomfortable, and gives me no context for my surroundings.” Next, he pointed to his nose. “For breathing air.It’s much more comfortable and has the benefit of scent. If I try to use it underwater, it burns like a motherfucker. Are we done?”

“You’re feisty,” Jude said.

“No, I’m sexually frustrated!” Toni seethed between clenched teeth.
