Hahhaha "quit it or I'll bite" (Also fyi "fight me you attractive stranger" was so much better than I even imagined, I was so excited about that one, it required caps lock) "life really sucks.feel better" And you. You feel better too :)
Clint laughed across at him as Bucky fished the little paper pellets out of his hair and Bucky bared his teeth in return.
“I’m sorry,” Tony said, “is this a briefing or have I somehow wandered into the SHIELD creche?”
“He started it,” Bucky said, and Clint grinned and stuck out his tongue.
“This,” Tony said to Bruce, who’d followed him in. “This is why I’m never having kids.”
“Oh?” Bruce said absently. “I thought it was Steve’s lack of a uterus.”
“I’ll admit that doesn’t help,” Tony said, swinging himself into a chair and grabbing the agenda from the middle of the table. Clint had already shredded his and was industriously rolling the paper into tiny projectiles. He picked one up thoughtfully and rolled it between his fingers.
“Try it,” Tony said without looking up, “and see if you get any more trick arrows.”
There was a moment’s contemplative silence.
“I wouldn’t,” said Bruce.
“Clint -” Bucky started, then swore creatively as another ball of paper ended up in his hair. “I warned you,” he said, and shoved his chair back with a loud scrape.
“You’re not seriously gonna -” Clint started, then “holy shit,” as Bucky leaned down and fit his teeth around skin, just where Clint’s shoulder met his neck. He bit down - not hard, but firm enough to feel it, to leave a red mark on Clint’s shoulder and warm salt against his teeth. Clint was frozen, completely still, a tide of red washing up his neck, and Bucky had to fight the urge to put his fingers where his mouth had been, slide them up Clint’s skin until he could feel whether Clint’s heart was pounding as impossibly hard as his own.
