Marco seriously hated Tom. 

"Seriously, what is your problem!?" He shouted, shoving Tom out of the way. "Do you really think I'd lie about Star not being here? What would I even gain from that!?" He started marching through his house. "Besides, Star and I aren't a thing! You made that all up in your own head!"

"Are you calling me crazy!?" Tom hissed, following Marco to his room.

"I'm calling you delusional!" Marco crossed his arms as he entered his room, turning around as Tom stood furious in his doorway. "Dude, I thought we were cool! You just came in here, demanding to see Star, who isn't here, by the way! And then blow up at me! What happened!?"

Tom went to say something, just to huff and clench his fists. "It's... It's nothing that concerns you! Just-" He glared at Marco- "Something about your face pissed me off."

Marco rolled his eyes. "Are you ever gonna grow up?"

That seemed to make Tom angrier, the demon growling and approaching Marco. For some reason, Marco was too upset to reason and stood his ground to glare at Tom. It never crossed his mind that Tom could easily kill him. He knew it was hot air anyway. If Tom really cared about keeping Star in his life, then he wouldn't kill her friends. He stopped in front of Marco, highlighting their height difference by trying to intimidate him with it. Marco just glared up at Tom. 

After a few moments of this standoff, something seemed to shift in Tom. His pupils dilated, his breathing picked up, and a low growl started rumbling from his chest. Marco was immediately on edge. Whatever was wrong with Tom, it seemed that Marco might have to fight him after all. Just when they were becoming friends, too. Man, this sucks!

Tom grabbed at Marco, the human instinctively dodging and stepping away from him, putting his hands up as the demon growled once again. He hit Tom with a few punches as he tried to get to the door, only to be yanked back as Tom finally got a hold of him. He struggled against the stronger teen, which prompted him to grip Marco tighter. He growled.

Marco's back hit his bed, and Tom pressed his wrists into the mattress, pinning him to the surface. Marco kept up the struggle, unsuccessfully trying to kick Tom off, grimacing at the hiss that Tom let out. He craned his neck to look at his door. If he could just get Tom off, then he could-

"Agh!" Pain burst from the junction of his neck and shoulder, making Marco gasp and squirm. 

Tom had sunk his teeth into his neck. Panic flared, his chest squeezing, heart pounding. What was he doing? Was he actually trying to kill him? He groaned as he felt warmth radiate out from the wound, the feeling spreading up his neck and down his arm. Was that venom? Tom had venom!? So he was trying to kill Marco! He pushed against Tom in a futile attempt to escape. He was an immovable rock, claws digging into his shoulders, keeping Marco in place, those teeth sinking further in. He tugged at Tom's shirt.

The growling that Tom was releasing had faded to a dull rumble, almost like he was purring. It seemed to calm Marco somewhat, along with the fact that he wasn't dead from the venom pumping through his body. Instead, his body had become warm, his nerves jumping and making him twitch. The teeth in his neck had started to feel... good. He bit his lip to repress a moan. 

Shifting his hips, he realized he was hard, straining against his jeans. Rather than the embarrassment and confusion he would have normally felt in a moment like this, he didn't feel much other than mild interest. Tom was straddling his leg, pressing his thigh against Marco's crotch, so he guessed that was why. Pushing against Tom once more, he concluded that he wasn't going anywhere for a while. So Marco started to grind against his thigh.

What? He had a problem to deal with, and Tom was pinning him to his bed, teeth deep in his neck. If he complained about Marco using his muscular thigh to get himself off, he could just point out that Tom injected him with some sort of venom, which he still had no idea what it was. He huffed, digging his teeth into his lip as he pressed into Tom.

The friction sent jitters across his body, the feeling much more intense than he expected. It felt fantastic and drew quiet groans and moans from Marco, despite his efforts to remain quiet. He whimpered as he felt Tom's tongue run against the part of his flesh trapped between his teeth. He grinded more earnestly against Tom, abandoning his shame and chasing pleasure. 

"T-Tom..." Marco groaned, feeling heat curl in his gut. Tom went stiff above him. Marco whined as he pulled back, removing the teeth from his neck and thigh from his crotch. He glared up at Tom. He had a look of pure panic on his face, a smear of red on his lower lip that Marco wanted to lick up.  Marco reached down the front of his jeans. "Why'd you stop? Feels good..."

"M-Marco, I'm sorry, I-I really messed up!" Tom stuttered, his face becoming a deep purple as he tried not to watch Marco touch himself. What, is he shy? Whatever, if he was that sorry, he'd put his leg back. "Gods, I shouldn't have come here! Okay, listen, I need to tell you what-"

"Ngh!"

"...A-alright, I'll tell you after you're, uh, done..." Tom squeaked, somehow flushing a deeper color. Marco didn't really care what he wanted to tell him. He buried his head in Tom's neck, quietly huffing as he worked himself.

"Put your leg back!" Marco demanded, moaning as Tom hesitantly lowered his thigh. 

Marco gripped the back of Tom's shirt, desperately moving his hips, whining as he got closer to his peak. His body was on fire, his nerves firing like a live wire. Tom was his lifeline as his mind went blank. He clung to the demon, pressing impossibly closer, shuddering at the feeling of his hot breath on his neck. It didn't take long for him to finish, his muscles flexing as he reached his peak.

"...Are you okay?" Tom asked quietly, pulling back to look at Marco's face. He nodded, letting his eyes fall shut as he enjoyed the feeling of Tom against him. "You're going to be so mad at me."

"Mmm, whatever," Marco muttered, moving his hips again, "I'll get over it..."

"Woah! Wait!" Tom pulled away like Marco burned him. "Why are you still worked up!?" Marco rolled his eyes, trying to pull Tom back down. He resisted, of course, looking down in confusion. Marco kept him from moving further away. "Oh, right! Touch!"

Tom tried to pull away again, but for some reason, Marco didn't want that. He gripped Tom's shirt, making a disgruntled sound as the demon tried to separate from him. He squeezed Tom. With a growl, Tom started trying to shove him off, the human fighting to stay together. Marco didn't even know why he wanted to stay glued. It just felt more right than what Tom was trying to do. With a final move, Tom freed himself at the cost of his shirt, which was pulled over his head by Marco's death grip. He sat back on his knees as Marco sat up, clutching Tom's shirt. Their eyes met.

"Marco, don't," Tom said firmly, glaring at him. Marco didn't listen to the warning, lifting the Tom-scented shirt to bury his face in it. Smoke and cedar. Refreshing. Tom groaned in frustration, face-planting into his hands. Marco curiously peeked at him. He raked his eyes over Tom's bare chest, his pecs, his stomach, and even lower, noticing... "You're going to be the death of me."

"You're hard," Marco responded, wiggling his hips. Tom flushed, looking down as if he had just noticed.

"W-well, yeah, I-it's part of what I need to explain." Tom huffed. "When you have a clear head. Now, give me back my shirt!"

Marco nuzzled the fabric. "Hm, no."

Tom blinked. "Marco, c'mon! Th-this is ridiculous!"

"Yeah, you're right about that." Marco ran a hand down his stomach, shoving his pants and boxers out of the way to free his dick, languidly stroking it as he looked at Tom through half-lidded eyes. "You come into my house, yell at me, pinned me to my bed, bit my neck, and now all I wanna do is jerk off while you watch." He hummed, tightening his grip ever so slightly. "It doesn't make any sense. You piss me off so bad, but you're all I can think about."

"Yeah, I-I figured..." Tom breathed, watching Marco run his shirt down his front. "I-I know why you feel like that, which is why you n-need to stop..."

Marco chuckled, biting his lip as he shoved Tom's shirt against his crotch. If he wasn't going to touch Marco, then he was going to use his shirt as a cum rag. He thrusted his hips, and gods, that felt good. Not to mention the way Tom was looking at him. Like a man who was starving, barely able to hold himself back. Marco watched in glee as Tom's tail made an appearance, the appendage flicking back and forth in irritation. He let out a dazed giggle.

"Hah! You wanna kiss me so bad that it makes you look stupid!" Marco laughed, speeding up his thrusts. His second orgasm was fast approaching, and Marco wasn't going to deny himself pleasure. "Gods, I wanna feel your teeth on me again!"

Tom's eyes were blown, his chest heaving, tongue flicking as if to taste the air. He hadn't been touched at all, but he looked wrecked, and all Marco had to do was touch himself. With a final groan, Marco released, limbs jerking and twitching, his load being caught entirely in Tom's shirt. The two panted, Marco leaning on his hands as he recovered, his bangs hanging in his eyes. However, just as Marco was about to reach for the shirt to see how his scent combined with Tom's, the shirt burned up, and the window was thrown open and quickly aired out the room. Shame, he was really starting to enjoy the smell of sex building up in the air.

"What was that for?" Marco asked, the heat rippling below his skin cooling quickly. Tom looked away.

"I'll explain everything." He said plainly. "As soon as you calm down."

"Ugh, whatever." Marco huffed, pushing off his soiled pants and boxers. "Get me a change of clothes, then, if you're so worried!"

Tom let out a long breath and stumbled to his feet. He grumbled, "You're lucky that this was my fault; otherwise, I'd smack you."

"...You can smack me if you want." The idea didn't sound so bad to Marco. Tom flushed.

"No!"

.

"You did what!?" Marco shrieked, his face burning red. The events of the past half hour were wreaking utter havoc in Marco's now clear mind. Tom seemed to be in a similar state, refusing to meet Marco's eyes. 

"I p-put you in heat," Tom repeated quietly, crossing his arms over his bare chest.

"How!? Why!?" While Marco was calmer, he still felt a dull heat beneath his skin, the place where Tom bit throbbing in a strange, pained pleasure. Tom curled further into himself.

"Let me start from the beginning," He sighed, running a hand through his hair. "So... it's, uh, it's b-breeding season-"

"Breeding season? Demons have that?"

"Shush! And yes, breeding season!" Tom took a deep breath. "I should have had better control of myself, but it can be... hard to control your impulses this time of year. Anyway, I came here looking for Star, because- well, you know why." He pinched the bridge of his nose. "So, right, here's the thing: demon flirting isn't exactly well-known."

"Demon flirting?" Marco whispered, flushing more.

Tom squeezed his eyes shut. "Y-yeah. I'm not blaming you. You didn't know. Okay?"

"Okay..."

"Okay." He cleared his throat. "Instinctually speaking, demon flirting entails aggression, a chase, and a fight. Typically. Technically. Usually."

"W-wait," Marco said, drawing Tom's gaze. "Are you saying... I accidentally seduced you!?"

"No! Uh, yes? Look, it's more complicated than that!" He glared at the ceiling, his tail flipping about in agitation behind him. "Technically, we did all the courting things. I-It was my fault for following you to your room, and when you didn't cower away from me, my body... my body decided that you would be a good mate."

Marco tilted his head. "Your body?"

"Yes, my body." Tom flushed. "I-it's kinda like when you find some random stranger attractive. A-and while you were just reacting to me being a dick, my body took your actions as... reciprocation."

If Marco's jaw could detach, it would be on the floor. Tom's demon instincts thought he was flirting!? He thought he was attractive!? He had so many questions!

Tom continued. "The fight just sealed it. Showing off strength is a major part of it, and, well, you throw a good punch. I-I lost control, and all I could focus on was getting you to submit. That's where the bite comes in." His eyes fell to Marco's shoulder. "You bared your neck, so I instinctively bit you, and-"

"Bared my neck? I looked at the door!"

"I-I know you were just looking at the door! It doesn't matter!" Tom huffed. "When I bit you, I injected you with venom! It's meant to-to make m-mating easier. If the pair isn't the same subspecies, anyway, different breeding seasons and all." 

"...Okay, so-" Marco took a deep breath- "The venom puts me in 'heat' to make s-sex easier. And this happened because we accidentally courted, and you found me hot?"

Tom grumbled, flushing a deep purple. "Yes. Now, are you gonna let me tell you the symptoms, or are you gonna keep interrupting me?" Marco pursed his lips and shook his head. "Good. Now, it should only last a week, you'll feel warm, have cravings, muscle aches sometimes, um, mood swings? A-and, you know, being horny twenty-four-seven."

"Hm, I feel like women are laughing at me," Marco mumbled, Tom raising a brow. "Okay. Is that it? No... surprise symptoms to be aware of?" 

"Well..." Marco rolled his eyes. "Shut up. Because I was the one who bit you, we should stay far, far apart for a while. My touch, smell, and just mere presence can be enough to rile you up, and, well, I-I guess you'll want me, or something."

"It makes me attracted to you?"

"Not necessarily?" Tom scratched his head. "I-I mean, I'll just be the preferred option, I think."

"What do you mean 'I think'? Are you just guessing all of this?" Marco watched Tom swallow. "Wha- seriously!?"

"Hey, I was only taught what it does to other demons! I don't know how it affects humans!" Tom huffed. "I-it should mostly be the same, but I... ugh! Here-" He snapped his fingers, a wisp of fire speeding from his hands, and at Marco. The heat seemed to sink into him. Marco couldn't stop the shudder that went down his spine at the feeling of Tom's magic. "There, now you can just say my name, and I'll be able to come to you to see what's wrong. Happy?"

"Yeah, thanks, Tom." Marco sighed, noticing Tom flinch when he said his name. He grinned. "Hey, Tom?" Another flinch. "Is something wrong, Tom? You're twitching a lot, Tom. Are you okay, T-"

"If you're going to abuse it, I'm taking it away!" Marco shut his mouth with a click, amusement clear on his face. "Okay. That should be it. I'm going to go now."

"Alright. See ya." Marco waved.

"Yeah, see ya," Tom muttered, hesitantly standing up. "O-only call my name in an emergency, okay?"

"Okay, I get it."

"Okay." Tom awkwardly glared at him. "I'm going, then."

"Right." Marco watched as Tom finally left.

.

Marco didn't really know how to feel on the first day. All the physical things he expected: he devoured the pancakes his mother made for breakfast, snapped at Janna a little harsher than intended, and his back was sore in a strange way. No, it was his thoughts about Tom that were confusing him.

It wasn't entirely his fault. Whether he meant to or not, he did trigger Tom's instincts when he was already on edge. Though, as Tom said when he was taking responsibility for everything, he should have had better control of himself and not gone to Marco's house in the first place. What would have happened if Star were there? She did date him before, so she probably knew how to reject a demon in breeding season. Though Tom has always had better manners around Star, so he probably would have had better control around her.

However, aggression is a part of the courting thing. Marco knew better than to start fights with Tom. He knew better than to feed into that energy. As soon as Tom entered that house, Marco did nothing except rile him up, and now he's facing the consequences of his actions. He was lucky Tom just bit him instead of tearing his throat out. 

Besides...

Marco flushed. It had felt good. Yeah, at the time it was mortifying, but he can't remember any other time masturbation had felt like that. He had always thought Tom was attractive (hard not to), so the memory of being pressed against him with his teeth in his shoulder was incredibly arousing. The mark itself sent out sparks of pleasure whenever he touched it. Perhaps it was the venom, but Marco couldn't help but enjoy the feeling. 

He rolled over, glancing down. He was hard. Right.

He reached for his nightstand. Well, if this was his reality for a week, then he might as well indulge. In the top drawer, hidden in a box that said 'puzzles for nerds,' was his lube and a toy he didn't use all that often. It was given to him as a gag gift by Janna (the asshole) just to see his face turn bright red. However, he never threw it away as she suspected. It was just a small dildo, made of silicone and ABS plastic, but something about it intrigued Marco.

He held the pseudo-penis in front of him. For some reason, Janna gave him a purple one. Was Tom's dick purple? Was it even shaped like a human penis? What if it were a tentacle that could move on its own? That would be weird. Not bad weird, to say, but different. He wondered what it would be like. Could they make it work if they tried? How would Tom like being touched? What would it feel like? What would it taste like?

Silicone, apparently.

Unconsciously, Marco had brought the dildo to his mouth, and the rubbery head had slipped past his lips. This wasn't something he had done before. Yet, instead of pulling it out, he slowly pushed it further in. He groaned at the feeling, images of Tom looking down at him flashing through his mind. This was beyond horny, but maybe it could be good practice, just in case. Should he be getting this turned on? 

He could practically hear Tom gasping as he pushed the toy further into his mouth, pushing his tongue against it as he drew it out. Would Tom prefer the push? Sliding past Marco's teeth and kissing the back of his throat (don't choke, don't choke, don't choke), or would he prefer the pull? Dragging his dick along Marco's tongue, gripping his hair as he guided Marco's head. (When did Marco pull his dick out?) He groaned around the toy, feeling saliva slide down his chin, gently suckling on the toy. 

He wanted those eyes on him, those claws against his skin, those fangs in his neck. Every part of him wanted to be marked, wanted to ache. He wanted Tom to yank his head around and force his dick down his throat. In theory, at least. The toy was only around five inches, and he could hardly get half of it in his mouth. Tom wouldn't want to hurt him anyway. He may be an ass, but he would be gentle with him.

Tom would cradle Marco's face and ask if he was okay, even if he was shaking with desire. He would whisper praises in Marco's ear, pressing kisses to his neck, listening to every sound Marco made. He moaned, sucking harder on the toy as his hand sped up. A memory bubbled up, one of Tom smiling at Marco, and for some reason, that sent Marco over the edge, the demon's muffled name groaned around the toy (no way he was accidentally calling Tom while masturbating).

He pulled the toy out of his mouth with a pop, sinking into his mattress to reflect. That was new. Especially that bit about Tom at the end. Tom being nice? Being gentle with Marco? Is that what he wanted? Is that just the venom? But that memory... he remembered that in that moment, he thought Tom had looked so beautiful. What was going on?

Marco sighed and rolled over to clean up. Whatever. He was tired.

.

Marco was already in a pissy mood that day (his throat was sore), and the last thing he wanted to deal with was Ludo's power struggle against Star. Normally, he wouldn't mind because fighting was a good way to blow off steam (something he really wanted to do since this whole 'heat' fiasco began), but currently, he found himself seething with rage as he fought the usual monsters. 

For some reason, it felt different. They weren't doing anything different, just attacking him and Star, trying to get the wand, etc, but every time one came close, he felt disgust rise up in his chest and he (far too aggressively) beat them back with all he had. There was no way he was going to let them get close, or even lay a finger on him. For some reason, he thought the monsters were acting... creepy. Not like in the typical sense associated with monsters, but the way one might consider a guy who wouldn't take a hint at a party.

Of course, despite his unusual violence, Marco was only a human and a kid at that. Buff Frog, with great struggle, managed to overpower Marco and pin him to the ground, his hands to his back. His stomach violently lurched. Then something strange happened. Deep from Marco's chest, a sound he had never been able to make before bubbled up, a vicious growl, a warning. Buff Frog froze. He leant down to sniff Marco before jumping away as if he had been burned.

"Ah! I am so sorry! I had no idea!" Buff Frog seemed flustered, making Marco tilt his head as he sat up. He refused to make eye contact. What... Marco paled. Could Buff Frog tell...?

"D-do I smell?" Marco asked quietly, his face burning. Gods, had people been able to tell the whole time!?

"No! No, it's not obvious!" Buff Frog quickly assured. "I-I was only able to tell because I got so close! Once again, I am very sorry! I'll keep my distance!"

Marco wasn't going to object as Buff Frog practically fled from him, the brief moment of respite allowing Marco to rest his sore limbs. The peace didn't last, of course, as Ludo shouted, "What!? It's human season!? We need to leave! Immediately!"

Instead of watching the monsters trip over themselves to get out of their dimension, Marco crossed his arms and tried to will away the flush undoubtedly covering his face. Star stood in baffled confusion, the exciting fight she was just in vanishing before her eyes. She looked at Marco.

"What was that? What's human season?"

Marco sighed. "Don't worry about it. It's just... a misunderstanding."

.

"Ngh!"

Marco ground down on the toy, trying his hardest to keep quiet. It had never felt like this before. He was burning with every movement, sweet heat sinking into him as he bounced, touching sensitive places that Marco was fairly certain he didn't have. It was worth the effort of cleaning and prepping himself, some sort of feeling being satisfied by having something shoved inside him. His legs trembled, yet he didn't stop. It was too much, it wasn't enough.

This would be easier if Tom were here.

Marco whimpered. Just the mere thought of Tom made his already boiling body flush further. He planted his hands on his mattress and thrust his hips desperately, feeling the ghosts of hands pressing against his body, imagining claws scratching against his skin, fangs scraping against the skin of his neck. He'd never admit it out loud, but it wasn't the first time he thought about it. What? He was a teenage boy, and Tom was not only hot, but a hot demon! It was new and interesting, and he was hooked immediately! He's allowed to have this secret. 

"Hf! T-mm!" Marco bit his lip, grabbing his cock and stroking in time with his thrusts. He was so close-! "Ah! Coming! Tom!"

Marco clenched down on the toy, spasming as he came in his palm. His eyes were squeezed shut, chest heaving as he came down from his high. He looked up, intending to get right to clean up, or round two, when he froze. There in front of him was Tom. The demon was wide-eyed, with a hand covering his mouth, staring at Marco. He flushed.

"Ah, I, um, I didn't..." Marco stuttered. This was humiliating. Caught jacking it, calling Tom's name-

"N-No, it's fine!" Tom looked away, a deep purple. "I-It's the venom! It was bound to happen."

"Right!" Marco squeaked, keeping his fantasies to himself. He cleaned his hands off and took a deep breath. As he lifted off the toy, his sensitive insides twitched, and he bit his lip to keep from making any unnecessary noises. Tom's gaze snapped over, taking in the purple dildo that slipped out of him. "...Janna gave me this a while ago. She wanted to embarrass me."

"Yeah, sounds like her," Tom breathed, staring at the toy. "...Why did you put a condom on it?"

"It's easier to clean it that way," Marco muttered, slipping the rubber off and tossing it with the used tissue. He quickly slipped his boxers back on. "Um, prevents infections? And most condoms are lubed, so..."

Tom nodded in understanding, watching as Marco quickly put all of his supplies away. He tilted his head as Marco settled back into his bed. "Uh, do you need some water? You sound a little..."

"Um, yeah, that would be nice-" Marco jumped as Tom summoned a water bottle in a flash of fire. "...Thanks."

"Are you hungry? Sore? Cold?" Tom crept closer. "Or maybe too hot? Oh! Do you need help getting clean? Or no, you look comfy, um... I can get you more pillows! Seriously, your bed is barren- you know what? It'd probably be better if I just brought you to my room. My bed's huge and I have so many blankets and pillows-"

"Uh, Tom?" Marco interrupted him. Tom blinked, jumping back. "Are you good?"

Tom backed away with a flush. "Yeah, sorry, it's just... My instincts want me to prove, um, th-that I'm a good mate. For you."

"Oh, gotcha." Marco sipped from the water bottle. "...So, you want to do things for me then?" Tom nodded. "Then...can I have your shirt?"

He could hardly contain the grin that threatened his face. Tom glared at him. Yet, the shirt was removed and thrown at Marco. Then the demon was gone in a flash of fire.

.

Marco leaned back against the wall, letting out a sigh as a cool wind blew by. It felt amazing on his flushed body. Normally, he would complain to others about the heat, but he seemed to be the only one who was feeling this way. A sudden, personal heatwave, making Marco sweat his own body weight of liquid. He was chugging water to combat it, but there was only so much that could be done. What was worse was that Marco's insides were aching, itching for touch. Humans couldn't exactly smell pheromones, but Marco was sure to douse himself in cologne. Just in case.

He watched the other students walk by, unknowing of his misery. Once again, his mind wandered to the cause of his struggle. Tom didn't tell Marco how long his breeding season was, but he assumed it was longer than this 'heat' thing, given that Tom talked about them separately. Was it like this for Tom? Or was Marco feeling more intense things due to the short period of his heat? Though even if it was less intense, Marco didn't want to know what it felt like to do this for longer than a week. He had great sympathy for Tom. 

He glanced up, freezing when he saw Tom across the way. He froze as well when their eyes met, looking away in guilt. Marco was struck with the sudden urge to drag him to the make-out closet (a janitor's closet that was always left open and barely visited by the staff). Instead, he pursed his lips and gave Tom a thumbs-up. He was fine, just a little hot. He wiped some sweat away from his forehead.

Tom chewed his lip. Then he snapped his fingers, a sudden burst of flame appearing in front of Marco. It dropped an ice pack in his hands. Before Marco could give an appreciative look, Tom was gone. He sighed.

He placed the ice pack on his forehead, ignoring the sizzle he heard.

.

Marco had been at it for what felt like hours. He couldn't finish. No matter how desperately he thrusted his hips, nor how fast he stroked his cock, he just couldn't reach that peak he so desperately needed to feel. Not even wearing Tom's shirt helped. He whimpered, tears pricking his eyes. It was starting to hurt. He didn't understand why his body was denying him relief. This wasn't fair! That stupid mating venom had him bouncing on his stupid dildo while thinking about his stupid demon! Stupid Tom.

"Ugh, Tom!" He groaned in frustration, freezing when he realized what he had just done. Right on cue, Tom appeared, not even surprised to find Marco in the position he was, wearing his shirt. If anything, he seemed... eager. Marco bit his lip.

He started moving again, a renewed energy pushing him forward. Tom didn't say anything, but stared unabashedly, following every movement. Arousal shocked Marco's system. A number of wants filtered through Marco's mind, from being bitten and scratched, to being pinned and fucked on every surface of his house. He wanted Tom's hands pulling at his hair, bruising his thighs, burning him with his touch. And he was so close to him, just one clever move would bring them together, finally connecting like they were always meant to.

"Hah, ah, Tom!" Marco panted, pure want filling his voice. "Tom, please!"

The wind was knocked out of Marco, his back suddenly pressed to his bed. He blinked up at Tom, who had launched forward and pinned Marco down. Hot air was blown across his neck, gentle hands drifting over his sides, a quiet purr reaching his ears. Instant relief rushed through Marco's body, and he reached up to cling to Tom, burying his face in his neck. Then he gasped. Tom had grabbed the base of the toy and slowly pulled it back, just to shove it back in roughly. 

Marco had to bite his lip to keep from screaming, the brutal pace Tom set feeling better than anything Marco had ever done to himself. The kisses pressed to the space below his ear had him shuddering, and he slowly got louder. A brief thought of waking people up filtered through his mind before it was silenced by Tom pulling him into a kiss. He eagerly swallowed down every noise Marco made, slipping his tongue into his mouth as he angled the toy just right.

Marco didn't last that much longer, clinging to Tom for dear life, kissing him like he needed it to breathe. Tom had to break away for him, his chest heaving as he gulped up air. His eyes fell closed, relaxing in Tom's arms, falling asleep to gentle kisses pressed to his temple.

.

Marco woke up clean. His sheets were changed, his toys cleaned and put away, and even his outfit was different. However, it wasn't his clothes he was wearing. The shirt he was wearing was baggy and comfortable, smelling of smoke and cedar. The blankets (his bed suddenly had many more coverings than before, several blankets and pillows added) were toasty, and made it difficult for Marco to get out of his bed. 

He managed to sit up a while later, the dull throb of his heat echoing beneath his skin. The bite mark on his shoulder felt fuzzy. Marco gently ran his hand over it, shuddering at the pleasurable feeling that followed. Memories of the previous night flitted through his mind. 

He licked his lips.

.

It was a blue moon that night. Marco sat on his bed, staring at the now huge moon through his window, his hands absently grooming his hair. He was wearing only a pair of boxers and the shirt Tom left him in. He had just taken a bath, scrubbing every inch of his body clean, even going as far as exfoliating and moisturizing. His bed was made, the blankets and pillows piled in such a way that they formed a sort of cove on the bed. All the relevant supplies were in reach.

He wondered if he should call for Tom or just continue on by himself. He didn't like the latter option. However, just as he resolved to do just that, Tom made an unexpected appearance. Their eyes met, a sudden sense of calm washing over them. Tom walked over, leaning over to nuzzle Marco's cheek, his hands finding his hips. Marco hummed. He crawled backward, leading Tom onto the bed and having him settle between his legs. The pillows cushioned his back as he relaxed, letting Tom lavish him with affectionate kisses and touches. 

Then, hands travelled under his shirt, warm hands pressing against his skin. His breath hitched. Tom's teeth grazed against his neck as the petting continued, his own hands pressing against Tom's back. Their movements were almost instinctual, natural, as if it were a dance they'd practiced before. Tom pulled down Marco's boxers, Marco pulling off his shirt in return. This allowed him to admire the view of Tom he got while his partner quickly got to work.

Tom's touch met his inner thigh. He bit his lip in anticipation. He watched as Tom muttered something under his breath, his body heating up as it sensed Tom's magic. Then a slick hand met his hole. He shuddered, grinding down eagerly, letting out a whine. Tom huffed, holding his hips still despite Marco's protests. Instead, he brought Marco into a kiss, sinking two fingers into him. Marco groaned in satisfaction. 

The touch made pleasing sparks travel through Marco's body, Tom's magic seeping into him with a satisfying heat. His body seemed to be more receptive than usual, easily opening up for Tom and absorbing whatever magic he was using. It made for a very titulating experience. Even better, Tom seemed hellbent on giving Marco as much pleasure as he could, quickly finding his prostate and abusing it. He was gentle even in his roughness, his bruising fingers a comfort on his thigh, his sharp teeth leaving a pin pricked trail of marks on his collarbone.

He, admittedly, let out a loud whine when Tom pulled his fingers out, the feeling of emptiness unbearable now that he's had a taste of fullness. Tom hushed him, reaching for the condoms and quickly ripping it open with his teeth. Marco swallowed. Tom shoved his pants out of the way revealing his penis, purple and red, fairly similar to Marco's, besides the ridges along the bottom. He was practically shaking in anticipation as Tom slipped it on, his stomach flipping when he got into position. 

The two paused as the tip kissed Marco's hole, the tension in the air palpable. Tom looked into Marco's eyes. He leaned down, bringing him into yet another kiss. 

"C-Can I...?" Tom whispered, voice so low that Marco almost missed it. He kissed Marco again. "I want to, so bad..."

"Yeah," Marco breathed, kissing Tom back. "Please, I-I need it-!"

Marco was cut off with a thrust, Tom finally entering him, finally filling him, finally giving him everything he needed. He stopped when he was all the way in, stopping before the two came too soon. They shuddered against each other, lips locked in a desperate kiss, satisfaction and pleasure running through their bodies. Marco couldn't believe that sex could feel like this. 

And then Tom moved.

It was a pure shock, striking Marco like lightening bolt, nearly sending him over the edge in one single thrust. However, the only thing he could think to want is more. He was given exactly that as Tom moved again. He tried to be slow and gentle, but was clearly losing his composure, growls and chirps echoing from his chest as his thrusts got progressively harder and faster. Marco could hardly keep up, clinging to Tom as the demon lost himself to the pleasure. The motions rocked the bed, lightly thumping against the wall with each thrust (everyone was out of the house luckily, which was part of the reason why Marco wanted Tom here).

Tom's claws dug into Marco's hips, yanking him back with each thrust, eliciting a cry of ecstasy with each impact. Marco dragged his nails down Tom's back. He could hardly take it. He buried his face in Tom's neck, sloppily kissing whatever skin he could reach. Then he opened his mouth wide, sinking his teeth into Tom's shoulder. 

Tom suddenly stopped, panting in Marco's ear. Marco let go, about to ask what was up, only for Tom to pull back and grab his wrists, using them to yank Marco's body even harder into his thrusts. He had Marco yelling into the night, the bed creaking dangerously with his movements, the slap of skin-meeting-skin echoing in Marco's ears. With a well aimed thrust, he pushed Marco over that edge, making him see white as his body quaked. 

"I hope you're ready," Tom whispered as Marco came down from his high, "because now, I don't think I can do you just once."

Marco shuddered and licked his lips. He grinned up at Tom.

.

Marco was sore. It was the first thing he noticed when he woke up. His back, his legs, his shoulders, everywhere hurt. The next thing he noticed was how pristine his bed looked with him tucked in it, each pillow and blanket perfectly placed. The third thing he noticed was the demon hunched over on his desk chair, head in his hands like he was contemplating his life.

"What's up with you?" Marco asked, his voice scratchy from all the yelling he was doing last night.

"You really are gonna be the death of me," Tom muttered. Marco rolled his eyes.

"What did I do now?" 

"'What did you do?' Honestly, I'm going to lose my mind!" Tom huffed, taking a deep breath before giving Marco a long look. "Well, Marco Ubaldo Diaz, let me inform you of something. Not only are we now bonded, since someone decided to bite me last night, it was blessed by the Blue Moon. Congratulations."

Marco blinked. Huh?
