Showed Me The Truth (Lust Sans)

Headcannons:
- Lust is very romantic, showing his affection in any way that makes you comfortable, be that flirting, showing affection, ot getting you gifts. If it tells you he loves you, he's doing it.
- His perosnal love language is physical touch. He gets flirted with so much that he doesn't care too much for it. Just holding his hand or kissing his cheek will make him a mess, if it actually means anything that is.
- The monsters of Underlust have a twisted idea of relationships, love, romance, and attraction. This makes Papyrus and Mettaton's relationship very strange unusual.

Fun facts:
- Lust avoids lewd situations when he can. He is somewhat self aware that he doesn't have to be like that, only doing what he needs to be done.
- Lust is one of my favorite Au characters, which is a bit ironic as an Asexual.

Notes:
- ⚠️Small Trigger Warning for Suggestive Words and Flirting⚠️

Cold air fills your lungs as you and Sans walk together, heading to Grillby's after watching a few movies together at Sans' place. You two were walking so closely that you almost stepped on each other as you went, seeming joint at the hip. The two of you were practically inseparable since you arrived down in the underground. The two of you just clicked in a way you can't explain, and now that meant you two were stuck with each other. Sans opens the door for you, allowing you to head inside the bar and find a seat. Despite the display that Grillby's was so popular for, you always found the food, music, and occasional karaoke much better. It was actually a great hangout spot if you overlooked the obscene views.

"Heya Grilbz. Can we get the usual please?" Sans asks, taking a seat beside you at the bar, scooting your chairs to be side by side. It didn't take long for the fire monster to return with ketchup, Sans' strange addiction, your usual meal for you to enjoy. As monsters poured in to watch the shows you stayed in quiet conversation with the short skeleton, enjoying one another's company as you ate the food in front of you.

A couple of monsters you had grown to despise, due to their lack of respect for personal space, walk up to the two of you with smug looks. The taller one leans on the bar right between you and Sans. Their voice hums with a teasing and flirty tone as they lean into your face, "Heya there, (Y/N). Funny seeing you here when you complain about it all the time. Looking for some fun, are you?"

You glare at them with annoyance, trying to lean back and away from them. "Not the sick and twisted fun you're talking about," you respond with a hiss in your voice. Satisfaction passes over you as he rolls his eyes in annoyance at your reply. You peek over their shoulder in an attempt to see Sans, he seemed to be in a serious conversation with the other monster.

Your attention quickly shot back to the monster as they leaned to block your view again. "Well, aren't you peachy? You should watch yourself, Love, after all this isn't your precious surface world. While you're down here you follow our rules and customs. That means our version of fun, the love we try to share." They lean in closer, making you able to feel their breath on your face. You try to lean back more but end up presse against the bartop. You silently prepared yourself to kick this monster where the sun doesn't shine if they push themselves any farther, but your thoughts were quickly interrupted.

A bone jutting up from the ground makes the two uninvited monsters jump back. Sans sends you a look, smiling at your amused chuckle. He had barely missed the monster's jaw, and you knew that was intentional. "Keep to yourself, if not, I promise it'll actually make contact next time. Your head on a spike can be a warning not to mess with (Y/N)." Sans crosses his arms, one of his eyes glowing like a purple flame.

The two monsters turned and rushed out of the bar, falling face first into the snow as soon as they made it out the door. As soon as you lose sight of them you look over at Sans, who was snickering, "Thank you, Sans."

He smiled at you gently, "I'm just making sure you're alright, sugar." His eye slowly returns to normal as he hops off his stool and offers his hand to help you off of yours. "You wanna go on a stroll? It'll help clear the mind. Plus we can get away before the show escalates."

You take his hand with a gentle smile, "Sure, good idea."

Sans takes you deep into the forest surrounding Snowdin, far enough out where you'd be hidden from the world for quite some time. It was peaceful and calm as silence surrounded you. The only sound was the crunching snow beneath your feet and the quiet conversation you and Sans had going.

"Hey, (Y/n)?" Sans nervously tries to change the subject of your conversation about the event just moments ago.

"Hm?" You respond simply, kicking up snow as you walk.

"That monster back there. What he said about the whole, 'love we try to share thing'. I know you've mentioned it before, but do we really not have the same definition of 'love' like humans on the surface?" He asks, trying not to seem rude or inconsiderate about how he phrased his question.

Hearing his inquiry makes you stop in your tracks, "Why are you asking, Sans? I mean yeah, it's different, but you've never really been interested in that kind of thing. I'd expect that question from Papyrus. Though, he surely knows the answer seeing how he writes."

He looks away from you and you swear you saw a slight purple hue on his cheekbones, "Just curious is all, I guess." He leans against the nearest tree, as if he was trying to be a bit more casual.

You walk over and tilt your head at the skeleton and is weird behavior, "You're not really the curious type."

Sans looks at you with a gaze of somewhat defeat, sliding down the tree and sitting against it now, "It's just....You've told me before, that what Papy and Mtt have is what love is and the surface. You showed me what love truly is. At first, I thought it was just a word used to justify each other's actions down here, or at least that's how we define it. But, now.... Now I see from watching my brother and hanging out with you that it is when you care for someone so deeply that you can't get them out of your head. You get happy when they even look at you, the sound of their voice is calming, and you feel sad when they aren't around. Love is... it'd when you know you'd do anything for a person, and I know that because... Well, I would do anything for you, (Y/n.)"

You sit down next to the stuttering and blushing mess of bones beisde you, gently leaning in his shoulder. The few seconds of silence between his words and yours felt like forever as you thought of what to say. Taking a deep breath, drawing in his comforting and familiar smell, you knew how to respond to this confession. "I'm glad I got to teach you how to love. You've taught me a lot too, how to be brave, stand up for myself, and how to know when to ask for help. If it wasn't for you, this place would've hurt me long ago. You make me happy, make me feel safe, and I don't know what I'd do with out you."

You get your face get warm as Sans puts his head on yoursz gently wrapping an arm around your shoulders, "I love you, Sugarplum. And I'll do anything to keep you safe down here. If we get out-"

"When." You corrected.

"Heh. When we get out, I can't wait to explore the surface with you. See everything you've told me about." He smiles wide, as if for once he actually believed that he'd be free one day.

That day may be far from now, but until then you both had each other, to love, grow, and cherish. Until the day you return home and the monsters are free, you knew that your inseparable bond would only grow stronger.
