Steve grazed his teeth against Tonys neck. "Why?"

"Because if Tony moans any louder i'll have Natasha shoot the both of you." Bruce looked up from his paper, taking a sip of coffee.

"That's why."

Steve blushed. "Sorry."

Tony smirked. "Who knew Captain America would be such a slut." He winked at Steve.

Steve blushed again.
