Confession

Sans's P.O.V
The whole gang was waiting for y/n to come over for the game night/sleepover. I was feeling nervous and giddy because I wanted to tell her something important. That I had a crush on her. I wasn't sure how I was gonna do it, I just need to be alone with her when it happens because you know Alphys and Undyne. It was almost time to start when the awaited guest was behind the door. I was going to grab the door but Papyrus beat me to it. He opened the door, and there was y/n looking as beautiful as ever. Her (e/c) shined from the light in room and her (h/c) hair looked so soft. I felt my cheeks heat up, but I quickly hid it. "WELCOME Y/N IT'S NICE TO SEE YOU!" Papyrus practically screamed. "Hey everyone! Sorry I was late, just caught up in some stuff." She explained. "Nah, it's alright kid." I answered care free sounding. The rest of the group greeted y/n until Undyne screeched, "I'M GONNA BE ALL OF YOU PUNKS AT MARIO KART! FWU HUHUHUHU!" (I think that's her laugh or...?)
Your P.O.V
I was so happy to spend time with all my friends, especially Sans. I have had a big crush on him for a while and I don't know when I'll tell him though. Maybe he doesn't like me. I don't know. After Undyne boasted about how she'll win, I sat down on the couch and sat down beside Sans grabbing a wii remote. Sans also grabbed one and Undyne started the game. I chose (character choice). I was doing pretty good at first, then Sans and Undyne started to beat me while I was just racing along in the background. Undyne was getting real mad at Sans now as he would pass or hit her with a calm look on his face. "Go Sans!" I say with a grin. "Thanks kid." He slightly looked over embarrassed but didn't realize Undyne passed him and won the race in a blink of an eye. "See! I said I would win!" Undyne bragged. "Something seems fishy about this, don't you think y/n?"Sans says with a mischievous look on his skull. Undyne's smile faded and turned to a suspicious one. "Yeah, we should get to the bass of this fishy problem." I add, smirking in the process.
In unison Undyne and Papyrus tell, "Ugh, I HATE those PUNS!" Sans and I burst out laughing while the others just watch. We finally calm ourselves and sit on the green, worn couch. Everyone else started to talk about who would play next so I gave a controller to Papyrus and Sans to Frisk.
Sans's P.O.V
Okay now's my chance to be alone since everyone else is interested in the game. "Hey y/n, ya wanna go walk to waterfall with me?" I ask nervously. A happy "Sure!" is what I hear. I lead her out the door and we start to walk. At first it's awkward but I start to make my usual puns that always make her laugh. We were nearing the waterfall and I was getting more nervous by the second. "So Sans, why'd you take me here?" She questioned looking me in the eyes. I could  stare at her eyes all day, but that would be creepy.... "O-oh! I wanted to talk to you about something." I reply. Ugh, why'd I have to stutter? "Well, what is it?" She asks sweetly. "Well, it's something important to me. I-I don't know how....to say it." I express. "Sans, you know you can tell me anything. We are friends after all." Y/n says with a heartwarming smile.  "Have you ever wanted to tell somebody something, but you don't know how they would react?" I ask quickly. Y/n replies, the words coming out of her soft lips,"Actually, I have. I don't really know how to tell them though either." My non-existent heart sank at what she said. Maybe she likes someone else? Ah, stop Sans. It doesn't mean she likes somebody. "U-umm well I want to tell them but I don't know how." I was getting an it impatient, but I didn't want to be rejected. "Ugh, I'll just show you!" I blurt out. I lean towards her and give Y/n a soft kiss on the lips. I could tell she was shocked at first, but started to kiss back. We pull back and I can see she has a dark red blush. I also notice I'm blushing my regular blue. "I-I'm so sorry! I shouldn't have kissed you without asking!" I stutter out. "Sans! It's ok, I've wanted to tell you how I've felt for a while too, but I didn't know how." She expresses. I feel a wave of relief wash over me and I pull her into a hug. "So this means you like me?" Of course it means she does Sans! Why else would she have kissed back?! "Yes Sans." She calmly says. I just smile, clearly embarrassed. We then walk back to my house hand in hand.
