I realized I tend to get lost in my dramatic headcanon stuff, so I miss out on drawing the cute and beautiful moments characters share.  
So here you go, some sweet Rarijack:
 
Applejack swiftly closed the door, as Rarity already put her arms around her waist.
 
“Hmmm…where have you been all day, honey? You know I’m impatient about…”
 
Rarity wasn’t able to finish her sentence. Aj’s sudden soft kisses and touches made her feel fuzzy and blood rushed into her cheeks.
 
She giggled and enjoyed the feeling.
 
“Ya won’t even let me buy a birthday present for ma sis, Rar. Y’all know darn well all ah could think about all day was you!”, Aj mumbled with her mouth pressed
 
against Rarity’s neck.
 
“Aww, darling-”, she panted, a little overwhelmed and joyful about the loving affection, “-I’m all yours…”
 
Applejack softly grabbed Rarity and lifted her without any struggle. Rarity then wrapped her legs around Aj’s body and they both started to chuckle.
 
“What do you wan’me to do with you now, princess?”, Aj whispered, kissing her cheek.
 
She knew very well that was her sweet spot.
