"Hey, Stevie!" Tony shouted to his boyfriend, who was right next to him. The blond rolled his eyes and looked at Tony with fake curiosity. It was Sunday morning and they were both in bed. It took an hour for Tony to convince Steve to stay with him until noon. The whole time they had been awake, Tony was doing something weird or just annoying Steve. Tony looked at his boyfriend curiously. "How did I even end up with you?"

"Do you want me to play the whole day I asked you out back?" Steve asked, raising an eyebrow. The question was definitely not with sarcasm, even though Steve had been using sarcasm lately way too much. Tony taught sarcasm to Steve only few days ago.

"No," Tony answered. "I'm just wondering... We started as a bomb. Now, we're in relationship." They both knew it was true. But after some time, Steve was able to call Tony his friend. Later, they became best friends. But they both knew they were something more.

The first one to admit the feelings to the other man, was Steve, who was toally freaked out at first. In 40s, who knew what could've happened with Steve. And even worse was that Tony's father Howard was Steve's friend. He had to talk with Pepper, to make sure it wasn't illegal anymore and that he can absolutely be in relationship with a man. After a month even Tony admitted he felt something more. They tried to stay apart for some time, but Pepper got them always in the same room somehow. It took some time, but they started to talk to each other again.

One night, they got into a small fight. Just some arguing and a few broken vases. During the fight, Steve accidentally said he liked Tony. The brunette was of course, shocked. And even worse was that the other Avengers were in the room. Steve's face turned red and he started to apologize, but Tony cut im off wih his lips, muttering something about how cute Steve was when he blushed.

Steve sighed and finally answered to the question: "I don't know."

Tony chuckled and moved closer to Steve, if it was even possible. His arms wrapped around him tighter. "You're so hot..."

The brunette felt moving and his eyes snapped open. He saw red on Steve's neck and he looked at his face quickly. Crap, he was blushing again. Tony's eyes locked on Steve's blush and he smiled slightly. "I meant temparature-hot. Though you are the other hot also."

Steve's blush turned slightly darker, as he looked away from Tony. "Why are you doing this?"

"What? Complementing my boyfriend?" Tony turned his eyes away from Steve's blush and to his blue eyes.

"Making me blush," Steve said, making Tony chuckle. He looked back at Tony curiously and kissed his forehead. "I know you're doing it on purpose."

Tony rested his head in Steve's bare chest and drew circles on it. "It's not my fault you start blushing so easily. And the answer would be: You're cute when you blush."

Steve's blush turned even darker and went even farther down. Tony chuckled, as he felt how much hotter Steve's body was suddenly. "You were the one who said cute is bad."

Tony turned his head to Steve's face, smiled at the blush and whispered: "That was before you taught me what it actually means." Tony pushed his body a little higher and leaned closer to Steve's face. "If cuteness was illegal, you would have death sentence, babe."

"Would you save me?"

"If I could live with the cuteness you have." Tony seriously couldn't stand Steve's blushing anymore and he leaned even closer to Steve, so the blond's exhales entered Tony's mouth. Tony smirked, when Steve's breath suddenly turned quicker and heavier.

"You already live with it."

Tony climbed on Steve's body. He whispered in his mouth: "I do" before cutting the space between them.

Reason 1: His blush is so fucking adorable.
