Sans x Female! Soldier! Reader

(Y/N) POV
I was hanging out with my kids Mia and Tyler for the last time. I have to go out in the war zone. I was playing the Wii with them until I felt arms wrapped around my waist. I smile and pause the game. "Awww come on mom." Tyler complains. I chuckle and turn around and see my lovely husband Sans. "Hey honey." I hug him. He hugs back. "Heh hey sweetie." I then hear gagging come from Tyler. I turn around not breaking the hug. "Tyler one day you will find someone you love." He makes a grossed out look. Mia then starts to laugh. Tyler is 10 years old while Mia is 9 years old.

"Can we play the game now?" Tyler complains. Sans then picks me up bridal style and sits on the couch. Hogging me. "No you had enough play time with mommy now I want my time." Sans says like a child. Mia laughs and turns off the TV. Then Tyler shouts,"Noooooooo!" He fell on the ground. He is so dramatic. Probably learned that from his uncle and cousin. Mettaton and Impact. Mia giggles and drags him away.

I then turn to face Sans. He cups my cheeks and kisses me. I hold his cheek with one hand while kissing back. We pull away and we stare at each other. He then hugs me. "Do you have to go?" Sans asks with such sorrow in his voice. I trained to go to the military. I got a message that I have to be at the airport tomorrow so I can go to the war zone. "Yes Sans." I kiss his cheek. He sighs. We have been friends for 3 years and dated for 4 years until he popped the question. We got married and had to beautiful human kids. They can teleport and use telekinesis but that is all. They also look a lot like me.

"I don't want you to go." He hugs me closer to him. I sigh. I look at him. He started to tear up. Then a blue tear slipped out. "I'm sorry Sans but don't worry I will be back." I wipe the tear away. He holds my hands. "What happens if you don't? You won't be there to help me raise the kids. You won't be there to help me with my nightmares." He hugs me and lays his head down on my shoulder. I hug back and rub circles in his back. "I will be back. I promise. Now enjoy my time here. I won't know when I come back. Now lets enjoy today alright?" I pull back and we face each other. He sniffs and nods. I smile and kiss his teeth. He kisses back.

We spent the whole day playing games, sleeping, eating, sleeping, watching TV. It was now night time and me and Sans were tucking the kids in bed. "Good night." I kiss their foreheads. "Good night mom. Good night dad." They both said in unison. Me and Sans leave. We walk into our bedroom already in our pjs. We get in bed. I look at Sans. "I'll be fine don't worry." He sighs and nods. I smile and kiss him. He kisses back. I wrap my arms around his neck while he wraps his arms around my waist. We then break the kiss.

"Lets sleep now." I turn off the light and we lay down. I face my back towards Sans. I close my eyes. I then feel bony arms wrap around my body. I smile. I hold his arms. I then drift off to sleep.

The next day I got up took a shower, and out on my uniform. I then see my taxi. I leave the house until I felt a tug. I look behind and see Mia, Tyler, and Sans. They were all crying. "Goodbye mamma." Mia and Tyler said in unison. I smile and hug them both. "Goodbye ny lovelies." I then break the hug and look at Sans who had Niagara Falls streaming down his face. I walk up to him. I hug him and he hugs back immediately. He shivered and sniffed. "Goodbye (Y/N)." I then felt crying myself. I don't know when I will ever see them again. We both pull away. One tear fell out of my eye. "Goodbye Sans." I turn my back away and walk into the taxi. We leave my house and off to the airport. I'm sorry.' I cry in the back seat. I wipe them away.

The next day

Sans' POV
I see (Y/N) shooting guns, killing people. But then I see her get shot in the head. I widen my eye sockets. I rush over to her but every time I took a step she is farther away. I run to her and now she is gone. I collapse on the floor. "You said you would come back." I cry. I cover my eyes.
