A/N: Just a little head's up, this is pure smut and nothing but smut. You have been warned.

Kate twiddled her thumbs anxiously over the coffee table across from Clint in their New York apartment.

Clint tried not to look at Kate as he looked over and cleaned the arrows that Kate recklessly had shot against a fleeing group of thugs, the tips now bloodstained a clear crimson. He sighed to himself, trying desperately not to look at his partner who was looking at him with a bright smile like she was about to deliver the best news ever.

"So…it's my birthday tomorrow" Kate finally said.

Clint nodded silently. He hadn't forgotten, they were partners after all in more ways than one. During their last Christmas together, she had confessed to him that she was in love with him and had been for a long time. This was…unsurprising to both himself and Laura as they could see the attraction from a mile way and considering the hero worship that emanated from her, yeah her confession was not a surprise at all.

But even to Kate's surprise, Laura had been alright with it, even encouraging her husband to go out and form a meaningful relationship with Kate, more then just work partners, but actually something more.

Kate had been overjoyed by this change in relationship. Her archery skills improved with her mood and once their relationship had become physical, well she felt outright unstoppable. Whenever they had the chance to be alone then sex was as inevitable as the snap. It was nothing special, nothing too kinky. But in her mind she wanted to spice things up a bit. And now she felt was the right time to try and ask that.

"And in case you were wondering what I wanted for my birthday, not that I assumed you had forgotten or anything but you know as Hawkeye we are kind of busy and…"

Clint interrupted her with a firm, short and simple "Kate say what you want."

Kate breathed in, put on her best sweet smile and said "well you know our bedroom life is great and all but I thought for my birthday we might…you know…spice it up a bit more. Not that you're doing anything wrong like oh my god you drive me wild with that incredible…"

"Kate" Clint said slightly annoyed.

"Right! Right! Right what I was going at. I would like us to try something I've been thinking about for quite a while. It would make me really happy if you could indulge me with that on my birthday."

Clint shrugged "sure. What is it?" he asked curiously.

"Well…" Kate said slightly fidgeting "I want you…to be my daddy tomorrow."

"Nope!" Clint instantly replied.

"What! Why not!" Kate exclaimed, crossing her arms.

Clint sighed audibly, his head in his hand as he gave a stern and an "ironically" almost fatherly look at Kate.

"Look Kate. You went through a lot, the attack on New York, you lost your dad back then. And normally I wouldn't mind indulging in your fantasies but this…I don't think this is a bridge I'm willing to cross. I don't want to bring up any past trauma's, especially not when we're intimate" he explained to her.

There was a notable silence for a minute before Kate finally spoke up, her arms dramatically in the air.

"Oh come on Clint! Me wanting you to be my daddy in bed doesn't mean I have daddy issues!" she said waving her arms around.

Clint raised his eyebrow. Kate immediately blushed and said "okay maybe a little but come on! Please Clint it's my birthday and I would love this!" she smiled with him and put on her best attempt at puppy dog eyes.

Sadly it had little to no effect on Clint.

"I'm sorry Kate. But no."

Kate's head fell in disappointment. It made Clint feel slightly bad, but he reckoned it was better then making Kate feel awkward and or uncomfortable especially when it came to their sex life. He wanted her to feel safe, wanted her to feel good. In his own head he felt this was a better solution.

However Kate did not seem to agree as she was now on her knees right in front of him, her arms around his left leg.

"Please Clint! It would make me so happy, please just this once!"

"Again I'm sorry Kate, but no" Clint reiterated, proceeding to stand up, only to have Kate continue to cling on to his leg as he tried to move, pulling her along.

"Please! Please! Please!" Kate begged continuously as she clung to her mentor and lovers leg.

And that's how it continued throughout the day. Often times she was on her knees begging for him to give it a try. Clint felt he really underestimated how much Kate wanted this, it was clearly not a spur of the moment decision but something she really had thought through.

Yet he felt like it was a bit too much and as such continuously told her no. Nevertheless she persisted and kept pleading him. And like clockwork Clint would reply with a stoic refusal.

Even now as he was reading the paper on the couch, Kate kept clinging onto his leg and giving him the puppy dog eye treatment which he ignored.

"Please Clint! I'll let you put it anywhere!" she begged.

Again there came a stiff shake of his head. Kate huffed and stood up yelling "fine!" and began to walk away. Clint looked after her, feeling slightly guilty. But as the night pressed on and no other word was spoken between them, he considered the matter as good as closed.

The following morning…

Kate woke up in her room, immediately checking the time. It was the early hours of 6:30 and she groaned at the fact that she was always awake so early. She grumbled to herself "happy birthday to me" before diving back into the pillows. That was until a deep voice said.

"Happy birthday indeed."

Immediately Kate was wide awake and turned the light next to her bed on. In the corner of her bedroom she saw him standing there. Clint. In nothing but his black boxers.

"Clint what are you…" Kate mumbled as the man stepped closer and placed a finger on her lips, shushing her.

"That's daddy to you."
