Taking herself off the market and jumping into the pool of dating was about the only "risky" thing Natasha Romanoff intended to do. It crossed the lines of many boundaries that were engraved in her mental "not-to-do list", she kept locked in the back of her mind. So when her boyfriend, Steve Rogers, accepted the job of being Peter and Morgan's official parental guardian for a week, she was far from pleased.
No, she was annoyed.
Tony and Pepper couldn't have picked a better time, did they? They had to wait until the beginning of summer, just when both the Widow and Captain were both free from their Avenging responsibilities.
She should've known though, the way Tony was hinting several nights before. They were having dinner at his and Pepper's little cottage by the lake. And little Peter and Morgan were more than ecstatic, to say the least when they laid eyes on their favourite uncle, Steve.
"Cap's got a way with kids, huh?" Tony raised an eyebrow while setting his glass of wine atop Morgan's hand-made, kindergarten coaster.
In the corner of her eye, he was in the middle of a wrestling match with little Morgan, both of whom were spectated by Peter. Natasha would have to admit, it was adorable watching your boyfriend play along with kids.
"Morgan, what do we do during dinner time?" Pepper didn't hesitate to call out after her daughter, after witnessing her pin down Steve, face down position.
The Captain feigned to struggle while the young female Stark mischievously giggled at the sight of her uncle's cry.
"We eat food on the dinner table!" Morgan answered matter-of-factly. It didn't take her long to haul off Steve and march to her seat at the table, as Pepper started counting numbers. Her brother, following her tracks.
"Yeah, I guess he does," Natasha answered Tony with a smirk, as Steve ardently took a seat adjacent to his girlfriend.
It was sort of a major indication that Steve was good with kids and everyone else they knew wasn't. And apparently it was enough for Tony and Pepper to consider the Captain and the Widow as their babysitters. For they planned a week's cruise to the Bahamas and Pepper simply couldn't wait to finally relax, after juggling her life between running a company and taking care of two rascals.
Natasha said they would "sleep on it". Apparently, to Steve, this wasn't the case. He didn't, not even the slightest, hesitate to accept the saintly offer. And after doing that, Natasha simply couldn't refuse. She didn't want to be deemed as the 'heartless aunt', who couldn't give two shits about taking care of anyone's kid or kids.
