“You need to stop acting so reckless,” Zamasu muttered as he wiped the blood away from a particularly deep gash on his cheek. He could heal it instantly– it would be the easiest and leave the littlest mess, but it also would mean that Black would just be back in a matter of hours with more wounds for him to path up. The red liquid stuck to his thumb, the metallic stench making him scrunch his nose up as he frowned down at him. “This plan of yours cannot be as effective as you assumed it would be.”
Black had simply laid down on the couch when he came back, putting his head into his lap so Zamasu could tend to his wounds. Maybe he liked the attention he got whenever he had to be healed, again.
The kai poked at the wound, Black's own body already working on closing it up. All the scratches were already gone, it was just this gash that wouldn't stop bleeding.
Black scoffed underneath him, grabbing his wrist to stop that hand from jabbing at him. “It’s enough to increase my power without spending years training. Besides, what else would we need the brat for? I could kill him, but..” Zamasu glared at him, daring him to continue his sentence. “..That does take away from the fun.”
“Right. And his strength also increases each time he survives.” Rolling his eyes, Zamasu watched the wound stitch itself back up as his healing did its thing. At least it wouldn't leave him with any more scars than he already had. He pulled his hand away, wiping his thumb clean on the dark gi Black wore. “You are better off ending him now that you have the chance.”
“But don’t you want to see how strong this body could get?” Black let his wrist go before sitting up from the couch. His hair was even messier than ever, the spikes sticking out in every direction except where they were supposed to. “Besides, if push comes to shove–”
“Fusion?” Zamasu confirmed where he was going, frowning when he nodded in return. “Would that really make us more powerful than we currently are? We do not know what it would do with the immortality we wished for. It would be a shame if we lost that just for an increase in power”
“But…” Black tried to argue back, his voice dying out when Zamasu leaned in. The cabin already felt small, the soft pitter patter of the rain hitting the window only adding to the isolated feeling. Zamasu pinched his earring between his fingers, wiping off the remaining mortal blood that stained it. “The mortals will not grow powerful enough to rival you, especially if your little plan works out.” Those slender fingers traced over his jaw next, brushing over the slight stubble before lifting his chin up. “Everything is going according to plan, there’s no need to think about such extremes, is there?”
“We-”
Those grey eyes stared back at him, squinting as the kai was trying to figure out whatever was going on in his mind. At the start it had been easy to guess, but the longer Black spent in a mortal body, the more it started to affect him. His other hand snuck into the loose strands of hairs on the back of his head, grabbing whatever bunch wasn’t all tangled up.
“Hm.” Zamasu pulled on those rough strands, just slightly enough to pull him back. “Do you really think I would be willing to blemish this body by fusing with a mortal?”
How dare he suggest that those– things would even come close to their power? Zamasu knew he'd be fuming if the roles were switched. But no, Black just smiled up at him, not talking back in favour of mirroring his exact expression. His head tilted, even with the hand holding him in place.
“Of course not. I wouldn’t dare question your strength,” Black’s hands ghosting over Zamasu's chest, sighing as he traced over those lines of fabric he knew so well, up his chest before ending at his collar. “But I do think that we should take into consideration the strength this body has. Especially once I reach the state it was once in.” The words came out as more of a murmur as he tugged Zamasu closer, nuzzling his face into the crook of his neck. He ghosted over the button holding his overcoat closed, nipping at the exposed skin on his neck. “Just imagine it. You and me getting rid of the last filth in this universe–”
His advances were put to a quick end when Zamasu grabbed his wrist.
“Just because I help you with your mortal desires doesn't mean that you have to project them onto me.”
“How am I supposed to properly worship a god when my hands are not allowed to wander?” Black smirked back at him before pressing a kiss to his neck. His sharp canines scraped against his skin.
“You– You can't be serious–” Zamasu spat out. His consciousness shouted at him to fight back, to put an end to this madness before he'd regret it– before either of them regretted it– but he couldn't. The soft touch was.. nice, comforting in an odd way, even with how his face ran hotter than it ever did before. Before he knew it the button came undone and the false saiyan was already undoing his stash. “Stop that–”
“Say that like you mean it and I will consider it,” he responded, nipping at his earlobe before nosing along his jaw. “Do you really think I haven't experimented before?” Black's fingers ghosted over his chest, lingering right at his collarbones before slipping the overcoat off over his shoulders. “I know you get those urges too, I know what I like, I know what [em]you[/em] like. There really is no better way for you to find out, is there?”
Black hummed as he tugged his undershirt up, ghosting his lips over the unmarked skin. “I'm sure it has been too long since someone worshiped you properly, why don't we change that?” The hot breath fanning against his skin didn't help Zamasu's deepening blush. He still had his hair in his hand, he could pull him away, but he did like the sound of those words.
“Ah-” the gasp escaped him before he could hold back as Black licked a long stripe over his stomach, right up to between his pectorals. “That's disgusting–”
Black smirked as his other hand slipped under his waistband, Zamasu's legs spreading ever so slightly without him even thinking about it– did he really?– was this normal? To want, to desire to such a level that it made his stomach turn? At least Black was acting like this was the most normal thing in the world.
He whimpered when he went even lower, brushing against places he hadn’t touched himself– ever. It was a mortal thing to sin, to soil a body with such desires. But he couldn’t worry himself with such thoughts when it felt so right, not when those skillful fingers took their time exploring, ghosting over long untouched skin, dipping into places–
“Right there, hm?” Black hummed back at him as his breath hitched, his fingers dipping between his lips, spreading the slick before ghosting his thumb over his clit. “I- oh-” Zamasu responded, his hips nearly automatically bucking up into that hand. It was a weird feeling, but definitely not unwanted, especially not unwanted when he slipped his finger inside, pressing into even more of those spots that sent shocks up his spine.
“To think that you'd never have been allowed to feel pleasure like this if I hadn't decided to show up,” Black sighed, tilting his head as he watched him. His free hand traced over his chest, before scraping his nails over the unmarked skin. His eyes were squinted slightly, a low hum in the back of his throat as he worked his fingers inside of him. Black would've cursed him if he compared it to a purr, but it totally was one.
“Just look at you,” Black sighed. Leaning in to kiss his cheek, he moved to his temple after, brushing away the hair that fell over Zamasu's face while doing so. Zamasu’s eyes fell closed when Black added a second finger, rocking his hand with a steady rhythm. “You’re beautiful.”
It took a while to get used to the feeling, but oh was it great once he did. Especially with the way he nipped at his skin, not hard enough to break – not that it mattered, but it was sweet that Black was showing some form of self restraint – but with enough pressure to send more of those sparks down his spine.
“I– I need–” Zamasu gasped when Black's fingers left him, his insides clenching around the sudden loss of contact. It was intoxicating. He needed more. More of that friction, more of that pleasure and more of that wonderful haze.
Their lips crashed together before he could even think twice, Black desperately nipping at his bottom lip, panting into the kiss and gasping for air neither of them allowed the other to get. Under any other circumstances Zamasu would've called it vile– shamed him for even suggesting something more than the usual peck he stole – but he needed this. He needed those sweet whimpers underneath him, needed to taste the inside of his mouth, needed to chase more and more and more.
“Zamasu,” Black managed to speak between breaths as he pulled back. Zamasu was almost saddened by the lack of contact, only confused for a mere second before that wonderful mouth returned to his neck instead.
“Zamasu,” Black continued his chant, scraping his sharp canines against his neck before kissing the soft skin. It wasn't harsh enough to draw blood – not that that'd really matter – but oh did it do something to him.
“Zamasu–” was the final warning he got before those teeth sank into his neck, breaking any important veins hidden beneath the surface, staining what was once still unscathed. He swore he could hear Black growl into the wound, or– no, he feltit.
He couldn't take it anymore.
“How–” Zamasu spoke between pants, releasing Black's arms in favour of grabbing him by the collar, pushing him away and back against the couch with maybe a bit more force than necessary. The wound stung, his blood stained his teeth such a nice shade of purple, who was staring back at him like nothing else existed, and he just had to know.
“How do we– how–” he sputtered, flinching as his neck regenerated whatever tissue Black tore apart mere seconds before. He couldn't even say it. Not that he had to, not when Black's knee pressed between his legs, finally giving him that wonderful pleasure that he needed. “Oh fuck.”
Black hummed in return, using his now free hands to pull Zamasu's pants down, tossing the piece of clothing away when Zamasu kicked the rest off. His hands traced over the now bare skin, up his stomach and over his pectorals, before going back down again over his sides. The slick still left on his fingers leaving an odd shine. “I thought you were all against mortal desire?”
“Just,” Zamasu swallowed as his hands went to undo the other's stash. The fabric quickly fell away, and he pulled his pants down to reveal his erection. Black was always quick to get hard, but he had never seen his cock this flustered. His thumb spread the bead of precum over his head, before dragging it down to coat the rest. “It's different.”
Mortal copulation wasn't something Zamasu could ignore after Black had admitted to the.. ‘downsides' of inhabiting a mortal body. At first the thought had repulsed him, until he got curious enough to ask the false saiyan about it.. and now he apparently got desperate enough to see for himself.
He placed his hands on his shoulders for balance, his insides clenching around nothing and his fingers digging into the fabric. It was hard to not stare at the dick below him– especially considering what they were going to do.
“It'll be easier if you stop thinking and actually do something,” Black said, placing a hand on his hips to guide him down. The skin to skin contact was way too warm, way too sweaty and way too much at once– especially when he finally felt him press in.
“Oh–” Zamasu gasped at the sudden pressure. The drag seemed to go on forever, his insides getting pressed further and further until they were finally flush against each other. “Shit, that's it,” Black cursed underneath him, his fingers scratching his thigh. The bloodied stripes he left behind quickly closed up again.
Zamasu’s legs trembled as he finally found the courage to roll his hips. He needed him impossibly closer, running his hands underneath the others gi to trace his skin. Black shuddered underneath him, bucking further into him and dragging his nails deeper into his thighs. “Fuck,” Zamasu hissed with a groan, his legs going weak and dropping his head against his shoulder, “I– I can’t.”
He barely even managed to utter the words out before Black cradled him. Cringing was an understatement at what he did when he was moved with.. that still inside him, but laying on his back definitely did feel way nicer than trying to keep himself up (and failing). Those hands cupped his face after, Black kissing his nose before leaving another on his forehead. “It’s okay,” the other mumbled, trailing the kisses down to his chest. “You’re okay.”
He waited until Zamasu composed himself before he started moving, careful at first, keeping one hand on the kai’s thigh to keep him down while the other folded his other leg back. His mouth idly nipped at the thin skin covering his neck, drawing more groans from him.
Zamasu’s hand covered his face, the sheer pleasure too much for him to even consider being any more vulnerable than this, especially when Black took it as a sign to quicken his pace. Yet he couldn't help not getting a peek- his fingers spreading so he could get a glimpse of Black looming over him.
Who was still closer than he expected, his nose almost touching his chest, one arm holding his leg back while the other was pressed on the couch for leverage, the fabric bunching between his fingers.
His other leg tightened around his waist when Black slowed down, daring him to even think about it.
“You're really not going to let me go, huh?” Black spoke with a chuckle, leaning in to nuzzle against his cheek, pressing a kiss to his temple as his thrusts became deeper instead, more calculated. “You'd really think I'd stop?”
Zamasu groaned in return, covering his face with his hands again. “You don't have to say it like that-”
“How do you want me to say it then?” That purr became lower, more dangerous. “Do you need me that badly? For a mortal to defile his divine counterpart?”
“You– you're disgusting,” he gasped as Black moved again, squirming underneath him. His hands abandoned his face in favour of Black's, cupping his cheeks before pressing their lips together again. The kiss was more tongue than anything else, but he didn't care, nipping Black's bottom lip when he slowed down again. “Keep going.”
The orgasm cradled him more than it took from him, his fingers digging into Black's skin as he gasped, his body tensing as he let the sensation wash over him. The haze was nice– wonderful even as it took him, lighting up his nervous system and making his limbs feel like jelly.
The only thing stirring him were the soft kisses littering the side of his face, Black groaning as he rode out his own climax, staining his insides with that disgusting liquid. He really didn’t want to be thinking about all of that right now. The entire experience by itself had been plenty to later ponder over while he waited for Black to come home.
“Don't,” Zamasu protested when he felt the false saiyan shift, wrapping his arms around his neck to keep him down. “Not yet.”
“I thought you didn't enjoy being filthy?”
“Not like–” Zamasu scoffed back at him. “Just shut up.”
He must've fallen asleep shortly after, the silence washing over him before he could protest against it, only to reawaken in a full, warm, bath, laying back against what could only be the other god.
“Ugh,” he grumbled, leaning his head forward to rub at his eyes, before splashing some of the water onto his face to remove the sweat that still lingered. His muscles still burned, protesting against every move he made even with the warm water soothing his skin. “You'd say that immortality would make it sting less,” he complained, feeling Black sit up to rest his chin on top of his shoulder. His shoulder which was chewed up mere minutes ago. Right.
He squinted, glancing to the side before straightening his back. “What is it with you and biting anyway?”
“M-wha–?” Black mumbled back, taking a second to mull the question over. “Oh. I don't know.”
“You don't– what kind of answer is that?”
“It just feels good.”
“Right.” Because that was just how simple it was, apparently. How odd that sometimes that truly was the only explanation.
