Summary
“What the hell’s your obsession with my clothes anyway?” he bites out, only half-seriously. It’s hard not to play along with Killer’s ramblings, but he just never seems to grow bored of it, much to everyone’s (but especially Cross’) chagrin.
“Tryin’ to figure out how y’even take it off. I mean, like, it’s gotta take at least half an hour,” Killer laughs. He’s leaning on the edge of the table like an asshole, folded arms and all. Cross wants the table to give way, because he knows Killer’s heading somewhere with that. “If you get in the mood, your cock’s gonna dissipate before y’even get to it.”
Of course.

Summary
Dream watched Nightmare at his desk, the scratch of a quill cutting through the quiet. There was no tension here. No fear. The press of negativity no longer suffocated him—it clung like a blanket. Heavy. Familiar. Comforting.
With each stroke of ink laid to parchment, Dream felt himself softening further—unraveling quietly.
He wondered, in a quiet corner of his mind, whether the golden apple lodged behind his sternum had started to bruise—skin giving way, sweet flesh turning dark, rotting slowly in the hush of this sweet corruption.
The thought rose like mist and drifted away. He realized, almost idly, that he didn’t care.

Summary
Blue considered himself the luckiest monster in all of the multiverse. After all, he didn't think just anybody got to bed the 'Destroyer of Worlds' and live to tell the tale- or even earn the title of datemate afterwards!
Blue was Error's datemate! And he took that title - as well as the very lovely privileges that came with it - very seriously.
Too bad he forgot to consider the responsibilities.

"Yeah? You want me to thank you?"
Between the exhaustion sat something unstable. Mania, sharp and wet in his tone.
"I want ya to think about what it’d be like if Killer or Dust were the ones taking care of you," Horror said, grin widening slow enough to show too many teeth. "They wouldn’t be half as gentle."

Killer grinned through the haze, panting. “Come on. Give it to me. I need your seed. Come on—fill me up. Knot me like a good little dog, soldier boy.”
Cross snapped.

Summary
He groaned, low and rough, the sound pulled straight from somewhere deep in his ribs. Cross dropped his face into his hands, burying the vivid flare of his skull behind trembling phalanges. “...And now it’s embarrassing,” he mumbled, his voice cracking beneath the weight of self-consciousness. “I’m so old and I have no experience—”
His hands slid further down, dragging along his face in theatrical misery before flopping back against the loveseat. “And then—” he sighed again, “I don’t want to kiss someone because they’ll be disappointed.”
It felt too honest. Too raw. The kind of thing you say and immediately regret.
He slumped deeper into the couch, like the cushions might swallow him whole if he just curled in enough. “Seriously,” he muttered, almost to himself, “who wants to kiss a thirty-year-old rookie?”

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
His eyelights were glassy, unfocused pinpricks of light floating within cavernous sockets. Fever radiated from him in waves, his bones glinting with the faint sheen of rising heat. Each shallow breath shuddered through his frame, erratic and unsteady, as though even the act of existing had become a battle.
The signs were unmistakable. Fevered. Overcome to the point of delirium. Every shiver, every labored breath, spoke of a body caught in the throes of a Heat so consuming that control had become a distant, unreachable goal.
For most monsters, this would have been ordinary—expected, even. An inconvenience of biology that, while inconvenient, was hardly unusual.
But this was Cross.
And therein lay the anomaly that hung in the air, thick and accusatory, like a question that demanded an answer.
"How curious," Nightmare murmured, his voice slipping into the room like a serpent through grass, low and smooth, almost inviting. His gaze never wavered, sharp and calculating as it swept over the trembling figure before him. "And here I thought you didn’t suffer Heats."

Summary
He kept circling, the way he always did—like he was waiting for Nightmare to flinch, or reach, or want. Nightmare didn’t move. He simply watched, tracking him with eye only. His gaze caught the wrongness in Sol’s gait—the favoring of one side, the stiff carriage of his wings. They were pinned tightly to his back, not spread in the usual theatrical sprawl. Defensive. Masked.
He hated that he noticed. Hated that he knew him well enough to see it.
“You’re stiff,” Nightmare observed. “Favoring your right side. You're injured."
Sol tutted. “Darling, if I said yes, would you kiss it better?”
“No. I’d tell you to stop being pathetic.”

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.
