Addiction
Thor grimaced as he looked from the light-golden wall of his bedchamber down at Loki who was still asleep. Long black-hair was feathered across the white pillow like spilled ink, the pale skin so pretty against the dark-red blanket. 'This is wrong, sex with my brother is so very wrong and yet I can't stop. It's like he's some herb I can't get enough of.'
Whenever he tried to stop all it took was one look into those big, mesmerizing, emerald-green eyes followed by a deliberately ragged, "Tho-or.", and he would give in.
Despite the fact that he should have left while he could, he leaned down and traced Loki's cheekbone with a finger. Loki sighed deeply and, so very guiltily, he watched the lithe muscles ripple taunting him to wake his brother. To lick and suck, to make that pretty body arch, writhe and moan in wild abandon.
He resisted the urge and trailed his fingers down the pale throat, over the pectorals, stopping to feel that heart beat strongly under his palm. It was hard to believe with how small he was, that Loki was just as strong as the rest of them. Maybe that was part of it too, that Loki just looked so vulnerable and even more defenseless than normal when he was asleep. 'Lovely Loki, my lovely Loki.'
Then Loki rolled to put an arm around his waist before starting to burrow into his side. It was so little that he ever got to see his brother truly relaxed. Why ? Because there was always some odd bit of tension between his brother, Sif and the others. If he ever managed to stop then this little bit of peace, when it was just them alone, with no one to interfere or tell them what to do, would stop as well.
'If Father makes me King it wouldn't be odd to see him coming and going from my room, he is, after all, my brother. I would need him as an advisor as well seeing how he paid far more attention to politics and such then I did.'
Until now, he hadn't realized just how much of his life revolved around Loki - his brother was everywhere, doing almost everything with him. Loki was an addiction to him, even more than the thrill of a new won battle.
His heart beat faster at the sleepily murmured, "Thor.", while those green-eyes fluttered open. Nothing could beat that rush of adrenaline and that was when he realized - it might be wrong, but he didn't want it to stop, ever.
