Yandere! Monster x Reader Headcanons
You find yourself kidnapped into a half-breed family of monsters and humans, for the purpose of an arranged marriage. Luckily for you, the groom is their only pure human, terribly handsome and charming. You'd perhaps appreciate him more if your eyes weren't glued to his monstrous older sibling...

[Part 2]

You always imagined such kidnappings to be of theatrical intensity, being scooped up against your will as you scream and flail your arms, longing for a savior. The affair itself felt more like a formal summoning. Mysterious men appeared before you and merely announced that your presence is required, unfortunately without the choice of refusal. Might as well. You packed necessities under their polite supervision and now you're sitting at the table, facing multiple strangers who are casually enjoying their lunch. One of them, the head of the family apparently, explains that half-breeds are in a rather sensitive place when one considers human and monster politics. Thus, every now and then, they will do whatever it takes to strengthen their bonds and show good intent towards both species. This time it's an arranged marriage with a fellow human.
Why you, in particular? No need to concern yourself with intricate details. What matters now is that you are to be married soon and your groom is right here, enthusiastically waving in a welcoming greeting. You scan his features and can't help but agree with the family: he is, by all definitions, a conventionally handsome man. His face is carefully chiseled in most elegant, yet masculine features. His voice is confident but warm, and you can tell by the flock of servants hovering around that he's rather popular. After the luxurious meal he guides you around the imposing home, showing you to your room and briefing you on future responsibilities. Caring, attentive, and several other checks that you can easily mark in his favor.
Yet one vital aspect has been omitted. The prince's mesmerizing beauty was rather swiftly discarded once you realized the presence of his older sibling, a pure monster blood towering above everyone else and idly eating his food, uninterested. You managed to hide your blush in time, but you couldn't help throwing curious glances. Might've been easier for everyone involved if they handed out 'monster lover' badges. Alas, you weren't prepared to ever be faced with the choice.
The next day you're awoken by the murmur of diligent work, as both servants and family pace back and forth about their plans. You sneak your way out - since nothing is yet expected of you - and wander until you find your intended target: the beastly sibling is polishing a bizarre weapon you don't recognize in what seems to be a storage room littered with battle memorabilia. He notices your presence and acknowledges you with a bored nod. You ask whether you may observe his current activity and he looks up at you, raising an eyebrow suspiciously before agreeing. Why would you care? Certainly there's more entertaining things for you to do as a soon-to-be bride.
As you listen to his little stories from the battleground (hardy monsters like him are better off fighting, not socializing), you have to pat your cheeks in desperate attempts to cool down your burning blush. "H-how comes you don't have a partner?" You mutter, almost feverish. "Not interested. Plus, who would dare to marry me?" he jokes, focused on the sharp item in his clawed hands. There it is. Hesitation and diplomacy out the window, you rearrange yourself, smoothening your clothing, and whisper: "Well, if I had to choose, I would've preferred you as my husband..."
Once again he stares at you bewildered. Have you come here to mock him or something? A frail, pretty human like you, about to tie the knot with his stunning younger brother, showing up here and behind everyone's backs to openly flirt with him. Ridiculous beyond comprehension. His skin is thick enough to not mind such twisted humor, so if anything he's impressed by your audacity. Alright, if you've come for jokes, he'll comply. He places his weapon down and fully turns to you. A little scare might teach you to be more respectful with your in-laws next time.
With a speedy movement that's barely registered by your eyes, he pushes you on the floor and pins you by the wrists, lowering himself uncomfortably close to your face. "If you tease me like this, I might not be able to hold back." He says as he forces himself to smile extra hard, revealing the multiple rows of fangs. "In fact, I can't guarantee you'd make it out of here alive." Hopefully he isn't going too far with his tactics. He senses your frantic breathing and is about to apologize for continuing your prank, but you blurt out in a daze: "Yes, please! I've been thinking about it ever since I saw you." You're panting for dear life as your face is turning a deep shade of red.
Uh oh. Now this is awkward. You weren't...you weren't kidding. For a moment, he freezes in place, trying to recollect himself to no avail. Fucking your brother's future wife in a storage room in the middle of the day feels like poorly written erotic romance. Then again, he can't deny the sudden urge overwhelming him at the mere thought of it. You're squirming underneath him, gliding your legs across his now obvious bulge. His common sense is hanging by a comically thin thread and he can almost hear the instant when it snaps. Thankfully some leftovers of sanity must have remained in the back of his mind and his lustful grunts while pounding you are kept low enough that no one is notified of your horny deeds. Shutting you up was the bigger challenge.
"Is this too tight, miss?" You spin in front of the mirror and the servant readjusts the lace corset adorning your wedding dress. You have to hold back your yawn. Downright shameless and perverted of you to daydream about your monster boyfriend while trying on bridal gowns, but it's not like you agreed to it to begin with. You were kind of hoping to discuss future dating prospects post-intercourse, but someone had been looking for you shortly afterwards and you struggled to regain your composure. Your scary-looking suitor shooed you away with the promise of a reunion.
Before the servant can reach for the next dress, you both jump, startled by angry shouts coming from the hall. You rush outside to witness the older sibling standing before the head of the family. The wrathful threats were coming from the much smaller half-human. "Y-you can't just decide like that!" He screams. "Of course I can. You're welcome to fight me for it." The monster sibling flashes a smug grin. "Can anyone here defeat me?" His question is met with silence. He spots you and gestures you to come towards him. "I'll say it one more time. Find another human for my brother if you have to. This one is mine." He ends his sentence in a low growl and you shiver underneath his heavy arm. Boy, what a time to be alive.
What You Can Look Forward to With a Big Monster Boyfriend

Your big monster!boyfriend will princess carry you regardless of what the situation is. Not only princess carry you but he is also perfect to be climbed on when you're still groggy from sleep in the morning and don't want to walk to the kitchen and eat. You can be like a big backpack, or you can be at his front, with one of his big arms holding you.
One thing that's a bit of a pain with your big monster!boyfriend is clothes shopping with him. Few clothes will bit him both in height and in width. He has to go to a special store for monsters like him, where you will get all kinds of looks and comments calling you a cute couple, which will make him very happy but also make him territorial.
For your big monster!boyfriend and you to sleep comfortably together you need to buy a big bed and a sturdy bed. Same goes with most furniture you owned. But when you moved to a new place together, one more accommodating to him you had a lot more space for cuddles.
Cold is never a problem with your big monster!boyfriend sleeping next to you. He sleeps completely cuddled up next to you, shielding your body from the cold or any sort of danger really. Not tense, he's very relaxed actually, however even in his sleep he's very entuned in the way you're breathing and your heartbeat, to make sure you're warm and safe and healthy.
No more reaching for high shelves with your big monster!boyfriend there to hand you everything you might need. No matter what your height, as a human there are limits, but he isn't beholden to those same limits. Unfair how he will use that to his advantage, holding the item you need high above your head until you kiss him, like he's some kind of high-school bully, but hotter.

The sex you will have with your big monster!boyfriend will get some time to get used to. It's not just his size but his other monster features such as fangs and claws and strength that could easily harm you if he were to lose control of himself. It's a learning curve for you both but you are very determined to one day have his whole cock in your pussy.
It takes a lot of time and preparation for your big monster!boyfriend to work his whole cock, and knot, inside of you. He has to take it slow for your sake, you both know it and if he has to be the one with a cooler head then he will be, he will hold your hips down when you try to take more cock then you're ready for. Growling at you to stay still only makes your pussy tighter around his girth.
With a big monster!boyfriend it's a given that there will also be lots of cum. A lot more cum then can fit in your human pussy, but well that's not a problem, you have two more holes he can fill up. You're not a quitter, and as long as his cock is hard you're be willing to milk his balls dry.
You need to get used to a lot of noises while you and your big monster!boyfriend have sex. Not just the noises the two of you and your bodies make: moaning, growling, whimpering, slapping, choking for breath, squelching. But also the sound of clothes and sheets being torn, the bed creaking and pushing against the wall, and yes even the occasional table breaking.
Your big monster!boyfriend completely looms, curls and envelopes you when he's on top of you. It makes you feel safe, it makes you feel fragile and god does it make you horny to know just how big he really is in comparison to you. He could snap you in half, he does sometimes fold you in half when he wants you to watch his cock splitting your cunt, and yet he is also the most caring lover you've ever had.

A/N: This has nothing to do with a Warrior Nun fic I read a while ago... nope.

"I was surprised at first, how easy it was to get you into this position." His long tongue licked the side of your newly exposed neck, "Then again you religious types are all to happy to get on your knees aren't you. All that kneeling, at least this time you get something good out of it." His hot hands roamed your body, pinching your nipples as he thrust into you from behind.
Of all the placed to let a demon, a devil take you it should not have been in the church. It shouldn't have been anywhere.
"To tell you the truth it worried me a little." He said thoughtfully.
"What did?" He was worried about you? That couldn't be right. He was only using you for his pleasure wasn't he? And you let him do it. Part of you enjoyed knowing that he found you so desirable to step into a place of worship.
Fangs pressed against your heated, wet skin, "That someone got to you before I did." His tail sneaked between your legs, trailing your shaking thighs before delivering a quick slap against your clit. "But no, of course you wouldn't do that. You were saving this pretty pussy. I'm flattered, human."
You shook your head, mind nearly blank as he kept bottoming out and rubbing his tail over your abused clit. "Not for you, devil."
"Of course not for me. For Him." His claws dug into your scalp as he pulled your hair and made you look at the cross, "That's what makes it all the sweeter for me. I get to take you, make you my own, make you moan in pleasure. Tell Him. Go on, tell Him how good my cock feels."
"I can't. I won't." If you admit to in front of God then... the Devil really will take your soul. You hated how appealing that was to you in this moment. But after? He would surely get tired of you.
"No? Then I should stop?" You whimpered as he started to pull out. "I shouldn't? You want more?" You tore your face away from his grip, eyes on the floor, fists balled into fists, "You can admit it. If you do so I will make you my woman, forever."
Your body moved in it's own, hips rolling back until your ass was against him, "Don't leave."
He pressed himself against you, your hips tilted up, head pushed down, "Then I won't. I'll be here every night when you come here to prey, to ask for forgiveness. I will teach you everything about pleasure, mine and your own. With how much I come in your womb they might think of you as the next Virgin Mary. Little will they know you're a the devil's cockslut."
Your pussy clenched tight around his cock, keeping him in while he emptied himself inside you, growling praise and sin into your ear.
