Papyrus actually not minding when Sans drinks a little too much because he gets cuddly. Pre-confession, it's one of the only ways to get him to sit still for more than a quick hug.

They end up on the kiss cam. Obviously they can't do anything much, so they shoot for a platonic forehead kiss. It's… still incredibly tender. Uncomfortably so.
One of my heart chambers will always explode seeing one of the brothers hugging a plushie of their brother.
At times, they'll find themselves utterly smitten. Say just the right thing, catch the light just so to become so dazzling.
But it's inappropriate, so their heads turn almost in sync. About to be caught staring, they look away.
Glancing by, just missing each-other. Over and over.
It hurts at first. It hurts worse when they realize there's nobody else that their souls call out to. But they get used to it.
It can't be helped.
Standing s☆x going on for so long that Sans literally can't stand anymore. The steady loss of energy and stability, knees wobbling, before giving out entirely. Papyrus catches him before he falls, but there's so many choices on what to do after.
♥ Stop for the evening
♥ Move to the ground/another horizontal surface
♥ Pick him up and pin him to the wall
♥ Dangle him by his wrists and keep going
hhh for any of those sleepover scenes where they try to be quiet, I'm imagining them finally getting a handle on their voices, but… there isn't much they can do about the squish. The squelch. They can angle differently to avoid the clack, but d☆mn, if you didn't want found out, why're you so wet… 👁️ 👁️
Body swapping before getting together. The obvious desire is to see their body, maybe touch it. But maybe that's too far a boundary. But their voice. Just looking at their face in the mirror and saying the things you want to hear. ... Still feeling appropriately guilty afterward.
Confessions that happen right before one of them goes on a date with someone else. Begging them not to go, desperate not to potentially lose them.
