Baby Brother: A Thor/Loki Story

Loki observed from his bed while his brother disrobed, garments coming off layer by layer, like he never was meant to have anything on. In the low light of the fireplace, his eyes glittered covertly with envy, betraying the otherwise bored expression he was certain was genuine; there danced inside him the unspoken anticipation that he was about to get fucked.

He was a dissatisfied child, aware his brother belonged firstly to him and unforgiving that Thor had given to others attention that was rightfully his own. His gaze trailed possessively over Thor’s golden skin, consuming without letting on, waiting. He still could feel the fluid running down his thighs, from when his double had lapped at his entrance.

Thor approached silently, parts of him Loki could almost taste illuminated untouched.

“Are you hungry, brother?”

Loki asked, legs sliding lazily apart, eyes cunning; when Thor had reached the bedside, he brought one hand to the back of Loki’s neck, gripping his hair with enough force it felt secure. He tilted his head backward and leaned down to kiss him, there was kindness in grasp.

“I could break this bed,” his voice came deep and low; Loki remained unfazed, “I remember.”

He observed with unintended anticipation on which Thor could not pick up, watching his brother’s hand trail the engraved wooden headboard, the metallic decorations at the corner. “Get your fingers inside me,” he said, and slapped Thor’s hand away. He rose to his feet with casual elegance that was decidedly male, and paced toward the wall with his back to Thor; there were marks on the white flesh of his back and behind which Thor knew were not his doing.

Thor frowned with irritation while proceeding toward him, he flatly asked, “What’s this?”

Loki had given them to himself; but it pleased him to hear unmistakable jealousy in his brother’s voice.

“None of your concern,” he said icily, and he caught something like the sulking expression of a hurt boy in Thor’s eyes. Thor didn’t get his fingers inside him straight away; he remained where he was, reaching to trace the red marks with exasperating gentleness.

“You’d have to do better if you want to stay,” Loki said, audibly annoyed; he was silenced when Thor’s large hand came over his mouth. He felt the digits go in past his lips, roughly enough that it verged on credible. His mouth stretched in a wide grin around them, he chuckled at the back of his throat; Thor’s fingers were long and calloused, a warrior’s hands, he’d always liked how he tasted.

He sucked on them loudly, deliberately profane, surprised when it felt like Thor was really trying to gag him; he’d finally learned what he liked. “Strike me,” he murmured, and Thor fucking did, Loki’s head hung toward the wall, fingers clawing at the wooden panel; he visibly reveled in this. His voice came strained but with unmistakable contentment when Thor struck him again, but then he muttered,

“Enough.”

He regarded Thor bitterly from over one shoulder, jealously, like whatever annoyance he’d brewed in him did not satisfy Loki that he was really special. The flesh of his behind stung tender and red, he reached absently to feel it; he wanted to give it to himself, and make Thor watch. He wanted to be bent completely on the sheets, shackled and exposed, unable to see how hard Thor would give it to him.

And Thor could really do it, that's the thing, Loki knew he had it in him— maybe if Loki only pissed him off enough.

The digits emerged from his mouth slick and brilliant, trailing wet on his cheek and humid with breath, he could feel Thor grip his behind before he got them in. Loki cursed under his breath, nails scratching at the wall, he reached with one hand to get the fingers in deeper.

Rapidly, so his eyes went open wide, glistening with something like shock while Thor couldn’t see.

“You get bored enough, you’d fuck anything,”

Thor’s voice came quiet and accusing; for some moments, Loki went completely still.

He turned his head just enough his canines glinted through his smile, like it couldn’t be helped. He chuckled like he so enjoyed being amused.

“Brother," he said, "I am dreadfully bored.”
