Ok First! This is a collab done with Pepethehuman this one-shot is based on her story "Drips of Red" (Seriously go read it it's my absolute fav story, dear lord) But seriously, if you don't feel like reading it, just know Reaper is a Vampire.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

While many vampires roamed outside, enjoying the few hours of moonlight they had left of the night, Death was trapped in his tower again doing paperwork. He grunted, desperately wanting a break before he heard a small knock on his door. "Come in." He muttered, loud enough for the other person to hear.

Death immediately brightened up at the sight of Geno walking in, holding something behind his back. "Hey, guess what I found." Geno said excitedly as he pulled out a small bag of jumbo marshmallows. Death said nothing for a good minute as he stared blankly at the other.

Geno began to feel nervous, seeing no reaction, but it washed away when Death finally spoke up. "I think I just fell in love with you again." He said quietly, making the smaller laugh. Geno walked up to the other and leaned back on the desk slightly, being careful with the items resting on it. Death watched as Geno carefully opened up the bag and hand him the first fluffy treat.

Death gently rested his head against Geno's 'stomach', happily enjoying the marshmallow. Geno smiled softly and set the bag down, taking a marshmallow for himself. He gently stroked Death's head, letting the other relax on him. Death hummed gently, closing his eyes and taking in the quiet moment, his arms neatly wrapped around the other.

This went on for about an hour or so, both of them sitting comfortably in silence as they soon reached the bottom of the bag. Seeing the last marshmallow, Geno smirked, getting an idea. He quickly took hold of the last sweet and placed half of it in his mouth. Instead of eating it, he let it sit and waited for Death to notice.

Geno refrained himself from laughing when he saw Death reach for another marshmallow and feeling none. Death's eyes blinked opened and looked at the bag, then to Geno, his heart stopping.

Death stared at Geno, slightly frozen in place. "Don't hurt it please." Geno nearly choked but managed to keep calm. He didn't say anything and just stared back at Death with the best-amused smile he could give, having a delicate marshmallow in his mouth. After a few seconds, Death realized what Geno wanted and immediately became flustered.

Geno watched as Death debated with himself for a good five minutes before he stood up and towered over the smaller. It was Geno's turn to become flustered as he looked up at the other, leaning back more on the desk. Death carefully leaned in close, gently wrapping both arms around Geno.

Nervously, Death took hold of the other side of the marshmallow. As he pushed closer, Geno loosened his grip on the sweet, letting Death take it. Death, however, didn't stop there. He pulled Geno closer, pressing his lips against the other in a small kiss.

Although it only lasted a few seconds, it was filled with a playful love that left them both smiling lightly at each other. Geno rested his head on Death's chest, listening to his soul beat against his ribcage while Death happily ate the marshmallow.

What the smaller didn't know was how the blood from his mouth smeared on the sweet. Death lost himself in the flavor of the mixture of the marshmallow and blood. His grip on Geno subconsciously tightened as he suddenly felt territorial for the other. Like he was afraid someone would take him away and he was ready to fight till his death to keep him.

Geno leaned back slightly, taking Death with him and causing the other to tower over him again. A small blush crept to Geno's cheeks seeing Death pressed against him and refusing to let go. He looked at the other, who had a distant look on his face. "Death? Are you oka-mph!"

Geno's eyes widened as Death interrupted him with a kiss. Not knowing what to make of the situation, he wrapped his arms around the other's neck and decided to just go along with it. After a few minutes, Geno managed to pull away, trying to catch his breath, only to have Death press against him and forced him into another kiss. Not that the other minded.

Geno heard the sound of papers being pushed away as he attempted to look back. He saw Death moving his papers out of the way, along with a few other items, and was pushed against the rather large desk. Geno opened his mouth to speak but was quickly silenced when Death shoved his tongue into the other's mouth, making him shudder at the feeling.

This went on for the next few minutes. Every chance Geno tried to take a deep breath, Death pushed further, trying to taste every bit of him. He wanted more of his blood, as to Death it was the sweetest thing that ever entered his mouth. It didn't take long for Geno to put two and two together, and since he knew how much the vampire loved sweets, he didn't mind. In fact, he rather enjoyed the attention he was getting from his lover.

Soon enough, Death pulled back for a breather. Both panted heavily as they stared at one another. Geno gave a quiet laugh at Death's dazed expression like he was in pure bliss. A bit of blood was on his lips and his fangs showed, making Geno shiver at the sight. He smiled lovingly and placed a soft kiss on Death's cheek, letting him rest on his chest, and stroking his head again like a tired puppy.

A few moments later the other instantly pulled Geno back into a kiss, Geno flinched in surprise but kissed back. Death tightened his hold on Geno's waist, slightly trailing a hand up and down Geno's sides. The smaller shivered and gasped, allowing Death to slip his tongue into Geno's mouth again.

"D-Death" Geno breathed out in a slight moan. Death hummed against the other's lips, pulling him closer and picked him up, sitting him on the desk. With another moan, Death guided Geno's legs to wrap around his waist and leaned forward making the other lay down.

For a while, Geno merely moaned out Death's name, driving the vampire nuts. Death purred quietly into the kiss and finally pulled away, he looked down to Geno and admired him. He loved how the other could look so precious and fragile while maintaining a strong and confident demeanor. He loved how Geno could make him feel safe and relaxed without saying a word. He loved how his blood could describe Geno so clearly. Undeniably sweet with a savory aftertaste, making him desperate for more.

The taller gently trailed his hand up to Geno's cheek. Geno panted heavily, trying to catch his breath from the kiss, as Death smiled down at him. Death leaned down and licked the blood off his chin before nipping at his neck making Geno tense slightly at the feeling of Death's fangs touch his neck and shuddered.

Death took noticed and gently grazed his teeth along his neck, licking slightly. Geno jumped slightly and made a noise that sounded somewhere between a yelp and a moan causing Death to immediately stop.

"Are you okay?" Death asked quietly and nuzzled the other gently. Geno gave a quick nod and looked away with his face burning with embarrassment. Death simply stared at him, expression both serious and worried. "Are you sure?" Death mumbled to the other, not believing the smaller. "Please tell me. He refused to continue if Geno was even the slightest bit uncomfortable.

Geno took a deep breath, swallowing his pride, and nodded "Yes, I-I'm fine." He managed to say through his embarrassment. Death smiled and leaned down to kiss his cheek sweetly, happy of the reassurance. Death pulled away once more and looked down at the other, trailing his hand on his side.

"Tell me when you want to stop.." Death mumbled and carefully tugged Geno's shirt up, exposing his damaged spine and lower ribs. Death stopped again for a moment, which felt like torture for the other and looked to him with concern. "...Will You be okay?" Death asked quietly. Geno huffed, slightly annoyed, but quickly calmed down when he noticed how genuinely worried Death looked.

He sighed light and intertwined his hand with the other's, rubbing it gently with his thumb. "Death I'll be fine." He said with a slight chuckle, "I know you won't hurt me."

Death smiled at the other and gave him a loving kiss to which Geno returned happily. The smaller silently hoped Death wouldn't keep stopping every five seconds since he felt himself grow more and needier for every passing moment. During their kiss, Death tugged Geno's shirt again and Geno momentarily pushed him off to take off the clothing, tossing it to the side. It didn't take long for Geno to notice Death staring at him lustfully, making his face burn in embarrassment.

He looked away and, after a moment, spoke up. "W-well..?" he mumbled. Death shook his head, snapping out of his trance as he gently laid Geno back down and carefully grabbed his spine, making the other jump slightly.

Death quickly stopped, causing Geno to give off a small annoyed growl, too quiet to be heard. "You okay?" Death asked.

"Yes." Geno hissed lightly, restraining himself from pinning Death himself.

Death nodded and carefully wrapped his hand around Geno's spine again. The smaller shivered, lightly but gave the other a small smile of reassurance. Hesitantly, Death slowly began to stroke his spine, gently kissing Geno as he did so. Getting eager the smaller quickly kissed back, feeling his body heat up rapidly. Death slowed down a bit, making Geno whine but quickly moaned as the taller went faster.

Geno wrapped his legs around Death's waist tighter, he brought him closer and gave off a small moan. He hissed when the other stopped to check if he was alright, and glared, pouted slightly. Death couldn't help but chuckle quietly at his expression. "Death, come on..." Geno whined, his body was starting to feel like it was on fire and with Death stopping every few seconds, was definitely not helping.

"L-look," Geno panted and gripped Death's shirt, "I'll tell you when I feel uncomfortable, so don't stop unless I tell you." Geno nearly growled at how annoyed he was. He was starting to feel too hot for his own comfort. Feeling a bit desperate, he pulled Death's shirt off and tossed it aside with his.

Death shuddered slightly feeling the air against his ribs and pinned Geno back down on the desk. He hesitated for a second but went back to nipping Geno's neck and brushing his hand against his ribs gently.

Geno gasped quietly and bit his lip slightly, he wrapped his arms around Death and trailed his fingers on his back, making the other shiver. Death quickly kissed Geno again, this time a bit more roughly, Geno hummed and moaned quietly. Death continued to kiss him and play with his ribs, rubbing them a bit more roughly but always made sure to be gentle with Geno's body. Geno started to moan a bit more loudly as Death used one hand to stroke his spine, and the other to play with his ribs.

Death continued for a while before leaning back, leaving Geno into a panting mess. Death felt his cheeks heat up at the sight of the other as he grabbed the hem of Geno's pants, looking down at him for permission. Geno nodded eagerly and kicked off his shoes so Death could take them off a bit easier.

Death leaned down to kiss Geno gently and slipped his pants off. He tossed them to the floor with the rest of the clothes and panted heavily, he looked down at Geno hungrily, holding back from losing himself and just furiously taking Geno right then and there.

Meanwhile, Geno kept himself from growling at Death for stopping again, he looked up to Death pleadingly and sat up, "Death please.." Geno whined and tugged at his pants.

Death snapped out of it once more and nodded, he quickly undid his belt and took off his pants. Even though Death barely did anything he already had a dick formed. Geno didn't really expect it and turned bright red, his breathing got a bit uneven as he body started to turn warmer.

Death pushed Geno back down on the desk carefully and kissed him once more. He rubbed his pelvis a bit roughly making the other moan loudly, Death continued and stroked his spine roughly. Geno squirmed slightly and moaned as his magic started to work, forming an entrance.

Death pulled away once more but didn't stop and he continued to stroke the others spine, much to Geno's liking, pressing against Geno's entrance. The smaller shuddered and drooled slightly, as Death purred and licked it along with some blood. The taller stopped for a moment and took Geno's hand, "Are you ready?" He asked as he was barely holding himself back from basically ravaging the other.

Geno took in a deep breath before nodding, "Yeah, g-go slow." Geno breathed out and shivered when he felt Death press the tip in. Death leaned down to kiss the other's neck gently as he pushed in, groaning at how tight he was. Geno tensed and hissed, it burned like hell but thankfully the other was careful and stopped halfway, letting him adjust.

After a while, Geno nodded and braced himself as Death pushed the rest in. He gently kissed Geno's neck and licked his collarbone to get his mind off the pain, and to distract himself from moving.

Geno gently tapped Death's shoulder, nodding at him to move. Death let out a relieved pant and kissed Geno, he pulled out slowly and pushed back in, making Geno shudder in slight pleasure. He continued doing this at a slow pace to make sure Geno was alright before he moved quicker.

Once he was sure the other was okay, he held Geno's hips and quickened his pace a bit. Surprised, Geno gripped the desk, almost clawing at it as he moaned loudly at how good it felt. The smaller started to buck his hips to match Death's thrust. Death let out a ragged breath and thrust roughly, nearly making the other cry out in pleasure.

Death began to almost pound into Geno, grabbing his hips tightly and thrusting deeper. The smaller grew louder as he felt a tight ball start to form in his stomach, but before it snapped Death pulled out causing Geno to whine loudly.

"D-Death what are you doing- hey!?" Geno yelped as Death quickly turned him over to his stomach was laying on the desk, "Deat-"

Geno was quickly cut off by his own loud moan as Death quickly entered him from behind, instantly pounding into the smaller hard and fast.

Geno gripped the desk tightly and moaned helplessly, his loud noises echoing around the room, somehow turning Death on even more. The taller thrust harder at an inhuman speed, Geno soon feeling the ball start to form in his stomach again making him drool in bliss.

It wasn't till a while till the other made a small scream as Death hit a certain spot, tears formed in Geno's eyes from the overstimulation. He screamed Death's name a few times before the ball in his stomach snapped, making him let off a loud moan as he released on Death. Death groaned feeling Geno tighten around him, with one last thrust Death released deep within Geno.

Both of them stayed there for a minute, both catching their breath. Death carefully pulled out and helped Geno up. He wrapped his cloak around the other, giving him a quick kiss before pulling him to his lap and sitting on the chair

They stayed like that for a couple of hours, till Death decided to take them down to the lower part of the castle to one of the bedrooms to rest.

I'm trying my best with these one-shots xD
