"...how 'bout I take care of you for a little while?"
Oliver raised his eyebrows and stared at David. Of all the things his boyfriend could've said, that might've been the last one he expected. The boy stayed silent for a moment as he stared down at himself, studying his childish features and attire and thinking on how nice it felt to be sitting on David's knee with his tiny self pressed up against his boyfriend's big warm body. He was so little. It wasn't really until now - with a grown-up to compare himself to - that he realized just how little was. And, to his surprise, he realized that he didn't mind one bit. The way he felt when he was in David's arms...small and safe and utterly loved and cared for...he hadn't experienced that since he was a child the first time. And if David was offering him a chance to feel that way a little longer...still, there was one thing bothering him. Oliver looked up and met David's eyes, the man doing his best to not laugh at the way boy's smooth jaw set in comical determination.
"Why'd you come over?" Oliver chirped. David's smile faltered.
"...I was coming to get my stuff."
Oliver frowned at his boyfriend, studying David's guilty expression.
"You were gonna leave me?"
"Yeah," David sighed. The strangeness of him having this conversation with Oliver while he - tiny and adorable and practically naked - was sitting on David's knee was not lost on him. "But seeing you like this...I don't know. I guess you're so cute that all I can think of when I look at you is how much fun we've had together - how much I really care about you."
"Stop it," Oliver peeped as he blushed and smiled as he avoided David's eyes. David chuckled and bounced Oliver a little on his knee, amused and fascinated at how light the boy was.
"I know it's not the most conventional sort of couples therapy..." David continued. "But maybe being like this for a while would remind each of us why we like the other so much. And it'd be good practice if we were to ever adopt a kid, like we talked about."
Oliver mused silently on this for a moment, a little smile still on his lips at the way David playfully bounced him on his knee. The feelings he felt towards his boyfriend, while still established in adult love, had become simpler, cleaner - a schoolboy crush, almost, a pure, deep affection that made Oliver feel as though the thing he wanted most in the world was to curl up in David's lap and snuggle against his impossibly big body. Anything beyond that felt alien, adult, icky. The grown half of his mind chided him for not being more upset at David - after all, he'd have been gone already if he hadn't found Oliver as a little boy - but the child half's desires proved too strong to resist. He wanted hugs and cuddles. He wanted to play. He wanted to be a good boy. Oliver looked up at David and gave the man a heart-melting grin.
"Okay."
David beamed, taking the child up in another big hug. Oliver's heart felt fit to burst as he, not distracted this time by crying, reveled in the warmth and security of David's embrace, feeling like the happiest and luckiest little boy in the world. David pulled back and gave the boy a chaste kiss on the forehead, which made Oliver blush and giggle and squirm.
"Alright then!" David exclaimed. "First thing we have to do is..."
