A/N: This is the spiritual successor to "All I Hear Is Your Gear" - because Mustang-owner!Blaine is my permanent head-canon. Thanks for reading, and please - let me know what you think and review!
Kurt should have been suspicious when Blaine casually mentioned that his parents were out of town this weekend on their drive to the Anderson home. And he should have been suspicious when Blaine accidentally spilled half a bottle of mangosteen pomegranate tea on Kurt's checkered shirt as they headed towards the house. And if neither of those things had made him suspicious, he would have been dumb to miss the fact that after Blaine had peeled the wet shirt off Kurt's chest, he had rushed inside to "make sure the coast is clear", leaving Kurt shirtless and alone in the garage with the new Mustang convertible.
Kurt, of course, noticed none of these things.
Unsure what to do with himself, Kurt wandered around the garage. He would be lying if he said he cared about sports cars. What mattered to him were heated seats, a luxurious stereo system, and inboard navigation.
Blaine's Mustang was a bright, almost eye-watering blue. The convertible top was black. Kurt would never have a car like this - it screamed obnoxious teenage boy - but it suited Blaine. Kurt supposed, sizing it up from the front, the sides, the back - that it was a good-looking car through all its flash, with a mostly masculine silhouette balanced with the slightest hint of feminine curvature. He had moved forward and was running a hand gently along the paint when hands slid around his bare waist and he started.
The hands tightened as Blaine's familiar giggle echoed from behind Kurt. "You do love Isabella after all," he cooed, letting Kurt spin to give him a look of disgust.
"The car has a name?" he asked, eyebrow raised.
"Of course, silly. All good, sexy convertibles have names. And hers is Isabella!"
Kurt wriggled out of Blaine's grasp, ignoring the puppy dog look Blaine gave him in response. "Sexy, huh? Now my boyfriend is giving vehicles girl names and calling them sexy. I'm getting jealous again." He grinned, but Blaine missed it since he was busy pinning Kurt into the car door and kissing him senseless.
"Don't need to be," Blaine rasped against Kurt's lips. His voice was low and rough and his mouth insistent, his teeth dragging against Kurt's lips. Kurt let out an uncomfortable squeak as he tried to shift his hips so that he wasn't in embarrassingly direct contact with Blaine's hip. But Blaine sensed his movement and pinned him against the door again, harder this time, grinding shamelessly into Kurt's hips and causing a high-pitched squeal to rip from Kurt's mouth. "You're much sexier than she is."
Kurt's eyes rolled back into his head and his fingers dug into his boyfriend's taut shoulders as Blaine continued to work. "Especially now that you're - scratching the paint - right now?" he choked out.
Blaine groaned as Kurt started to reciprocate the movement. "Worth it," he almost slurred, struggling to form words. "So worth it."
