Revenge
It had always been clear to Steve that Natasha Romanoff wasn't the kind of person you wanted as your enemy. He'd learned early to respect and also fear her abilities, and that it was wise to keep her on his side.
Maybe he should have known that making fun of her cooking abilities – it had been a loving tease! – wasn't the best thing to do to a woman like her.
As he woke up, his head was pounding painfully and he couldn't remember how he'd gotten into his bed. The fluffy feeling in his head only faded slowly, and he also became aware of a burning pain in his butt. Assuming that Natasha had kicked him following what he'd said, he shrugged it off and decided to take a shower, still wondering why he felt so shaky.
There was no way he'd been drunk, as it was completely impossible. In the bathroom, he turned the water in the shower on so it would heat up and undressed himself. From the mirror, a tired young man with blond, disheveled hair stared back at him, and he just decided to turn his back to him when he spotted something.
His eyes widened in shock as he tried to get a better view on his behind, hoping that he was dreaming, but even after rubbing his eyes it was still there.
In only his boxershorts, he ran through the Avengers Tower, finding Natasha in the kitchen, where she was eating breakfast with Tony.
"Natasha, what happened last night?" Steve asked as he came to a halt in front of them, thinking that he'd spotted a small, triumphant smile on her lips.
"I don't know what you mean."
Her innocent look was well practiced, but it couldn't fool him. She knew exactly what he was talking about.
"I mean this!"
With that, he turned around and pulled the shorts down a bit, revealing a bit of his arse and the fresh tattoo that decorated it. Tony cocked his head to the side with an impressed expression, examining the piece of art for a moment before he looked at Natasha and said: "Nice work. Where did you learn that?"
"Bangkok," she answered casually, reaching out to adjust the protective foil that was over the tattoo.
"And how am I going to get rid of this?" Steve exclaimed, his expression a mix of anger and desperation. "I can't walk around with a tattoo on my arse that says 'Property of Natasha Romanoff'! And we also have to talk about the fact that you knocked me out to tattoo me!"
"Revenge is sweet," Natasha simply replied, shrugging before turning her attention towards her yoghurt.
