"It won't be much longer now," said Blaine in the gentle, dreamy tone he always got when he was painting. Kurt thought it sounded like he was turning into Luna Lovegood. "Almost done…" he moved the brush smoothly across the canvas, leaving Kurt mesmerized at the flex of the muscles in his bicep. "Okay." Blaine's smile was blinding, proud and satisfied at his work. "You can come here and take a look."
Kurt rose from the couch and came to stand behind Blaine. "Wow, Blaine… It's so beautiful!" he sighed.
Blaine blushed, fiddling with his brushes. "Thanks." A moment later, he tilted his head to the side, cracking his neck, and groaned.
Kurt pressed a light kiss to the side of his throat. "Hurts?"
"A little," Blaine turned around to lean into Kurt's embrace. "Strains it a bit, leaning over the canvas."
"Come on, I'll give you a massage while this dries." They walked out of the studio, leaving the canvas, which was painted in Blaine's most vibrant, warm colors, alone. It was showing Kurt lying shirtless on a couch made of flowers- they were Blaine's signature- his muscles tensed under the skin. Every last bit of it, to the finest detail, had Kurt's body and Blaine's skills combined. Nothing could ever express their togetherness more.
Ahh! It's my 100th drabble! This has truly been amazing so far, and I couldn't have done it without you all. Can't wait for what's to come!
