AU Sanses Boyfriend Scenarios (M4F)

When Someone Threatens You

Requested by @POISOND_CUPCAKE

Undertale:

You and Sans enjoyed walking together. You would often do it to let off steam after a stressful day. Or just enjoy each other's company when you had to get out of the house.

This time, however, something was different.

You constantly felt watched. You kept glancing at Sans, scared. He noticed your worried glances.

"(Y/n), are you... Okay...? You seem really uncomfortable..."

You shook your head, and suddenly froze, stiffening. You ran off, trying to run as far as possible. You heard Sans calling you, telling you to come back, but you didn't listen.

You were going to get hurt...

You hid in an alleyway, curling up by some cardboard boxes. A stray dog had lived there that you had cared for the moment you saw it.

The dog walked over, smiling at you. You handed it some meat, and it's tail wagged. It happily ate. You smiled, but then you heard footsteps. Angry, heavy footsteps.

"There you are, you traitrous b****..." You heard.

You looked up, seeing someone you really didn't want to.

"(B/n), hi!... uh... what are you d-doing here...?" You stammered. Your brother looked at you with a stern expression.

"You lied. You do have a boyfriend. Just a monster. You know the punishment."

A glint caught your eye. You backed away, the dog getting in front of you and growling. The glint was a knife. The one you had thought cared was about to kill you.

You suddenly heard, "Hey there, buddy... why are you picking on the lady?"

"Sans..." You thought, scared for his life more than your own.

When your brother turned around, he lunged for Sans.

Yet...

The skeleton had teleported to you, and teleported you and the stray dog away. You steadied the canine, and pet it gently. It barked at you, smiling and about to lick your face.

You stopped it, "No."

The dog then licked your arm. You smiled, and let it.

"Better. Good dog." You pet the dog, and it barked happily.

Sans sighed, "Who was that idiot?"

".... My brother..."

"What?! Why would he be-?!"

"He's as bad as my parents..." You stood up, and began walking home. "He pulled a knife, and then you showed up... I was worried you were going to get..... killed....."

"You were scared for me? I was scared for you! You-!... You were going to get stabbed had I not distracted the guy..."

"I'd be fine. I could've handled myself." You smiled, "Come on. Let's go home."

"What about the dog?"

"... What do you think?"

"... Here, you hold it here, I'll go buy supplies." Sans smirked, teleporting off.

You looked at the canine, and it barked, looking at you happily. You looked to where the horizon was, and smiled, kneeling down and holding the dog.

Sans came back, with a harness and a leash. You gasped, "We're keeping it?!"

Sans nodded, and you hugged him. You put the harness on the dog, and clipped the leash to it. The dog walked calmly beside you.

Sans glanced behind him for a minute, glaring, before walking with you.

He would protect you no matter what.

Edit(10/5/2021): Guys, when I said that line I meant Sans would protect you no matter what, not the dog. For reference, later in the story: "the dog is female, and named Scarlett." The reason? I wanted to make it easier to read and easier on my sanity-

Underswap:

No one even dared. You were a force to be reckoned with. Anyone even looked at you wrong, and well... Blue would have to remind you to stop being so tense time and time again.

Underfell:

You and Sans were out for the day. It was calm. Nothing wrong.

Until you were pulled into an alleyway. Sans hadn't known, since he was inside a shop at the moment. He told you to wait outside, attempting to be romantic.

You looked to the person who pulled you there, and almost screamed, but he held a knife to your throat.

"Quiet now... we wouldn't want any cuts would we?"

The guy put pressure on your neck with the knife, causing enough to almost break skin. The knife was sharp. You could feel each point touching your skin like a razor.

You trembled, but kept quiet. Then, Sans rounded into the alley, seeing your fear. He saw the knife, and almost fainted then and there.

But, his protective side was shining through first.

His eye flared up bright red, flickering with a flame. He would protect you. Now and forever.

You stayed still, tears beginning to form. Sans was there, bones around him, but until he knew where the guy was, he couldn't get a clear shot. He had to take a risk.

He fired three bones, one over your head, and one on either side.

It worked. The knife was off your neck, and the guy laid dead in the alleyway.

You ran to Sans, hugging him. He hugged back, feeling you shaking intensely.

"Sweetheart, let me see your neck..." He whispered, gently coaxing you to lift your sore neck.

You resisted, the pain of lifting your neck up immense. The knife hadn't gone deep, but it still broke skin and hurt like hell. Finally, Sans managed to gently hold your chin up.

Luckily, only small drips of blood. You whimpered a bit, but Sans let you back into his arms, allowing you to keep your head down. You did see a doctor, and eventually healed fully. But you were scared to go out alone afterwards.

But that worked well.

Sans was scared to leave you alone for ages. Even when he stopped hovering over you all the time, you still called for him.

But that was only for a while.
