Author's Note: Just a little fic I came up with and thought I'd share. Rated M just in case, enjoy!

Barry phased through Arthur's door. "Arthur-" he cut off abruptly as he spotted Arthur with a towel slung low around his waist, drying his hair.

"Yes?" he asked.

Barry tore his gaze from Arthur's glistening torso with a blush. "I forgot my question," he blurted.

Arthur's lips curved. "Well, come back when you remember," he suggested.

The Speedster turned and let himself manually from the room. Arthur chuckled softly.

Seconds later there was a knock on the door. "Come in!" Arthur yelled.

The Speedster opened the door and poked his head around. "Alfred wanted to know if you have any requests for dinner?"

"Nah, I'm good with anything he comes up with."

"Okay," he replied, retreating.

Arthur shook his head in amusement. A minute passed, and there was another knock on the door. "You can phase in Barry!" he called.

The Speedster did so, a cute blush staining his cheeks. "I want to apologise, I shouldn't have let myself in," he blurted.

Arthur's lips curved. "You can let yourself in whenever you like," he invited. "I don't mind."

Barry's head tilted. "Are you an exhibitionist?"

The blonde laughed softly. "While I have no qualms walking around shirtless, no, I'm not an exhibitionist," he replied with a grin.

"Then why…" Barry trailed off, his mouth dropping. "You're attracted to me?!"

Arthur stalked to the Speedster, lips curving in a smug smile as the brunet was unable to stop himself from staring at his chest. He gently tilted Barry's chin up until their gazes met. "You have no idea how adorable you are, do you?"

"No?" he breathed.

"Guess I'll just have to prove it," he retorted, and dipped his head for a kiss the brunet eagerly responded to. Arthur cupped the back of Barry's neck, and the brunet rested his hands on the blonde's waist.

Arthur pulled back. "Your hands can go lower," he tempted, "if you want to."

Barry swallowed hard. "Is that a trick question?" he asked breathily.

He chuckled wickedly, and gently stroked the back of his neck. "I don't want to move faster than you're willing to," he spoke gently. Barry's mouth opened. "And yes, I realise how ironic that is, considering you're a Speedster."

Barry licked his lips. "We don't have that long before dinner," he breathed.

Arthur grinned. "Well then, I guess we'll have to pick this up later."

"Promise?"

He tugged the Speedster against him, so he could feel how hard he was. Barry shivered. "Promise."

"We could always skip dinner," the brunet suggested, causing Arthur to chuckle wickedly.

He gave him a soft kiss. "Tempting, but you can't afford to skip meals," he pointed out. He stepped back. "You might want to leave…unless you want to see what you won't be able to touch until later?" he purred. Barry blinked. Then blushed. "You want to see?" The brunet nodded mutely. With a smirk, Arthur dropped the towel. Barry whimpered. "You okay Barry?"

He licked his lips. "I don't know how you're going to fit, but I really want to try," he spoke breathily.

"We'll build up to it," Arthur assured. "Now, I think you'd better turn around, or you really will want to skip dinner."

"Okay," he spoke reluctantly and turned his back on the blonde.

Once changed, Arthur curled around the Speedster from behind, nuzzling the brunet's cheek with his own. "Just so we're clear, I want to date you, Barry."

"Exclusively?" he breathed.

"Of course," he growled, nipping the brunet's earlobe in reprimand.

"Sorry, it's just, you found Diana attractive," he blurted.

"I'm Bi," he stated with a shrug. He felt how tense the Speedster was against him. "She's hot, but I don't want to date her." He sighed as the brunet remained tense. "I can be possessive, so if this isn't what you want, tell me now." Barry turned to face him, biting his lower lip. "What is it?" he asked in concern.

"I just can't believe someone as attractive as you, could want to be with just me," he admitted.

Arthur linked their fingers together. "How about we take it slow until I can prove it to you?" he suggested.

"I suppose," he sighed. Arthur leant forward and kissed the brunet sweetly.

Barry pressed his lips together as the blonde pulled back. "No, you're right," he admitted. His expression turned shy. "Arthur?"

"Yes Barry?"

"I look forward to when you've proven it to me."

"Me too."
