The sound of giggling only gave Hugh a split second warning before Nate tackled him, wrapping his arms around his waist and nearly knocking him over all at once. He almost might have been knocked over for real if Nate weren't - thankfully! - strong enough to keep them both standing.
Nate giggled obnoxiously in Hugh's ear for a moment, then began yelling before Hugh could snap at him - or grumble sardonically that he was almost as heavy as a Snorlax, "Come on, Valerie, help me out here!"
Hugh attempted to struggle out of Nate's iron grip. If it were only Nate, Hugh would have eventually managed to wrestle away from him, but his little sister attached herself to his leg in an instant after Nate called for her and he was forced to resign. Feeling pleased with himself over the victory, Nate snuggled into Hugh's neck and grinned. Valerie did the same holding onto Hugh's leg, and muttered about how much she loved her older brother.
"Guys, this is really embarrassing."
"But we looooove you!" Nate exclaimed, louder than necessary.
To emphasize his point, he tightened his grip on Hugh. Valerie chimed in her agreement happily.
"Th-that's great and all, but... I need to breathe!"
If one tactic wouldn't work, Hugh could always try another.
"Huh? Oh." Nate let go, took a step back, then grinned back sheepishly at Hugh. "Sorry 'bout that. I guess we sort of... forgot?"
"Sorry 'bout that," Valerie repeated. She took a glance at Nate, then moved next to him and imitated the face he was making toward her older brother.
Lately, they were getting along a little too well, but she enjoyed Nate's company too much for Hugh to scold either of them for it. As wonderful as it was that they got along, sometimes the two of them together was overwhelming.
"But it's only because we love you!" Nate assured him.
"Because we love you!"
They looked about ready to jump him again. Hugh immediately darted backwards and held his hands up in protest.
"No, no, no! I got it the first time, once is more than enou-"
At least the second time, Nate took care not to crush his ribs. Valerie reattached herself to his leg, because she wasn't tall enough to reach much higher than that yet.
There was a kid across the street from them watching, a little slack-jawed, and Hugh cast an annoyed glance in his direction. After all, it was completely normal for teenage boys to be randomly hugged by their boyfriends and little sisters in the middle of town for no apparent reason at all, wasn't it?
...He honestly couldn't blame the kid for looking shocked.
"Next time," Hugh sighed, "could we at least stick with holding hands instead of making a scene?"
And underneath his breath, he was muttering, "It's lucky I think the both of you are so cute..."
Since whining about her lack of official name hasn't gotten me anywhere yet, I've updated my fan name for Hugh's little sister with a better one that makes more sense and fits in better with the rest of the universe.
Hugh - Hue
Valerie - Value
...Now all I need is a "Saturation".
