Asgore telling me he's proud of me after passing an exam with flying colors and feeling like my soul just got hit by lightning (in a good way), standing over Asgore and sliding my hands under his ears around the back of his head to gently grasp his horns and use them to tilt his head back so I can give him a deep kiss, playing Halo CE with Asgore and walking around with him on Blood Gulch to teach him what all the buttons do (he accidentally blew me up with a plasma grenade and felt really bad about it despite assurance that it was funny)

Going to a restaurant and debating whether I should take the booth seat right next to Asgore so I can have easier access to touch his fluff or the opposite booth so I can have a better view, polishing Asgore's armor until I can see my own face ogling his pecs reflected back at me, patching up Asgore to the absolute best of my ability after a battle and taking great care to kiss everywhere it hurts to make it better
