    Summary

    What do you do when you have an idiotic teammate who doesn’t fuck off? You fight him. What do you do when that doesn’t stop him? Well, simple. You tell him how much you hate him, though not through means people would normally describe as ‘ways to tell someone you hate them.’

    title from ‘i’m so crazy for youuu’ by rebzyyx :)

    Summary

    “You and I will both take turns breeding Cross. If the child is mine, you and him will remain in the castle. If the child is yours, you are both free to leave. That sounds fair, doesn’t it?”

    Cross was quickly becoming overtaken with panic. Regardless of either situation, Cross would come out of this with a child. He wasn’t ready for such a commitment yet, and yet, something in the depths of his soul stirred at the thought of carrying.

    Regardless, it was no longer his choice to make.

    Dream turned back towards Nightmare, finally unsummoning his weapons. His hands were balled at his sides as he spoke, his voice strained. “I accept.”

    Summary

    “I…” Dream’s voice cracked, raw and uneven, as he tried to form words that refused to come. “I don’t understand.”

    Nightmare’s response was a low, velvety croon; slow and deliberate. “You wanted your brother back, didn’t you?” The satisfaction in his tone was unmistakable, a rich, indulgent amusement curling around each syllable. He was enjoying this—savoring it—the way Dream’s composure cracked, his visible surprise. Nightmare found himself hilarious, and he made no effort to hide it. “So I brought him for you. I even wrapped him up for you.”

    Nightmare’s hand rose, unhurried, to cradle the cheek of his younger self. The gesture was almost tender, but the reaction it elicited was anything but. The boy flinched at the touch, his entire form shuddering violently. His bones rattled, each sound a sharp note within the stillness of the room. Silk bound his mouth, tied tightly enough to gag him, the fabric pressing into the grooves of his jaw.

    It was clear he didn’t know what was happening.

    Nightmare offers Dream a gift.

    Summary

    But above all, he needed respite. Reprieve from him—that winged menace who pursued him so relentlessly, weaving his presence through every corner of Nightmare’s existence like a stubborn breed of weeds blooming within a carefully curated garden. The Guardian had grown weary of waking to the detritus of the other's so-called affections—feathers gleaming on tangled sheets, gifts of gilded opulence scattered like relics of an unwanted ritual. And the offerings...half-dead prey left at his door, as though the predator fancied himself some grotesque approximation of a devoted lover.

    It was a pantomime of courtship, insufferably clumsy and wholly devoid of grace.

    He hated it all. Hated the clinging sweetness of it. Hated the resemblance of his brother whom he despised. Hated this creature of obsessive devotion.

    And so, he resolved to end it—if only for a moment. A trade, a fleeting concession, performed with all the precision of a blade slicing clean through bone.

    Nightmare strikes a deal, using himself as payment. More is taken than agreed upon, naturally.

    Summary

    This is where any one off smut I write will be going until my autism and ADHD go off the rails and I loose interest then eventually become even more obsessed with months later :)
    This is my first time writing on Ao3 however I did have some works on Wattpad (None were smut). I will eventually make a fluff and angst version of this and ones for other fandoms! Also feel free to make requests however I can never guarantee that I will write it.

    Summary

    “Shh, sweetling,” Sol whispered, his voice a low murmur against the curve of Dream’s acoustic meatus. The tone was silk spun with thorns, indulgent and unapologetically crude. “You’re so pliant like this. Did you know that? Such a pretty thing, even when you’re trembling.”

    Dream’s SOUL hammered against his ribcage, a wild, frantic rhythm that echoed in his skull. He tried to speak, to protest, but the words caught in his faux-throat, swallowed by the haze of his mortification and the lingering pull of sleep.

    Summary

    (T/n) is a renowned archaeologist, and researcher. He was on a ship with his research team heading back to the USA, but midway through, their ship encountered an island, and he has no idea how it ended up wrecked and him being the sole survivor.

    He would probably have been hysterical if he hadn't encountered living skeletons, which he decided to make his research subjects. But amidst all this, can someone explain to him what the heck an alpha is and why his research subjects seem so cooperative with his investigation?

    Maybe, a bit too cooperative.

    ------------------------------------------------------------------
    (T/n) es un arqueólogo, historiador e investigador reconocido. Estaba en un barco con su equipo de investigación, pero en medio camino, su barco se topo con una isla y no tiene idea de como termino su barco destrozado y él mismo siendo el ultimo sobreviviente.

    Probablemente habría estado histérico de no haberse encontrado con esqueletos vivientes de los cuales decidió hacer su objetivo de investigación. Pero a todo esto, ¿alguien puede explicarle que carajos es un Alfa y por que sus objetivos de investigación se ven tan cooperativos?

    Tal vez, un poco demasiado cooperativos.

    Summary

    There aren't many fellow skeletons in the Underground you've gotten to meet, let alone one as much a bundle of joy, questionable jokes, and relish stench as Sans. After a fun evening out, you decide to crash together at your place, and it doesn't take long for both of you to want to put your ecto junk to use in more ways than one. You've got no clue how skeletons can have ecto parts, but they're an a-bone-dance of fun, so neither of you question it.

    Summary

    It wasn't an innocent request, of course not. But it wasn't like Ink was unaware of that fact. To play along was something more than duty, after all. That was the way of love, wasn't it?

    or

    Ink and Nightmare roleplay a scene of The Odyssey. They fuck.
