Marriage is what you make it
When Merlin awoke the next morning, it was to the feel of warm arms wrapped around his midsection and a hard body moulded against his own. His immediate thought was, "Oh god, what have I done?" before his brain caught up to his sense and he realised that the feel of the arms did not remind him of mornings from long ago, but of times far more recent. He was sharing his bed, not with Will, but with Arthur; Merlin had never felt more relieved.
The sensation did not last long, however, as the question broke as to why he was sharing a bed with Arthur? He remembered a fight. He remembered hitting Arthur, albeit not very heart, he remembered thinking the whole thing had played out like a very bad soap opera, the writer of which deserve to be shot at dawn. He did not remember going to bed with Arthur.
He squirmed, twisting around until he was face to face with his companion. Arthur's face was scrunched up in distaste, a clear sign that he was awake.
"Stop wriggling, Merlin." Arthur instructed, tightening his hold on the other boy in an attempt to limit his movement.
"What are you doing in my bed?" Merlin demanded, settling down nonetheless.
Arthur snorted, "I think you'll find that you're in my bed." He responded, eyes still firmly shut. "I must not have locked my door last night, when I came back you were already here. You must have been very drunk if you couldn't even tell the difference between your room and mine."
A glance over Arthur's shoulder informed Merlin that his lover was indeed telling the truth and that Merlin was the one in Arthur's bed not the other way around.
Sighing, he burrowed deeper into Arthur's warmth, nestling his face against the other boy's chest. "Arthur? About last night –" He felt Arthur wince.
"Can't we just forget about it?" The other boy asked, pulling back to look Merlin in the eye. "We were drunk, I said things I didn't mean –" He broke off and sighed.
"I love you." Merlin offered quietly, praying fervently that Arthur did not throw the words back in his face.
"I love you too." Arthur admitted, resting his forehead against Merlin's, gently. Merlin shifted forward until he was pressed against Arthur from chest to feet and wrapped his arms around Arthur's waist.
"Go to sleep, Merlin." Arthur commanded, effectively ruining the tender moment between them. "We'll talk about this more when we're not so hung-over."
Merlin chuckled, and nodded his agreement, letting sleep reclaim him as Arthur began to snore softly against his cheek.
