Frisk POV:

"Saaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaans." I called. "What's up kiddo?" He asked as he walked in. "I need your help!" "With?" "Planning a party!" I yelled. He laughed. "For?" "You ask a lot of questions." I grumbled. "It's do Papyrus! I saw on the calendar that his birthday's coming up!" Sans stopped dead in his tracks. "Oops... I forgot." "Well then let's go!" I cheered as I dragged him out of the house.

We ran to so many different shops and grabbed decorations and food. "I'll call Undyne and Alphys to help out." I said and Sans nodded. "You should cook. You're food is amazing." Sans said which made me blush. "Thanks." I smiled. He kissed my cheek and I noticed a faint blush on his cheeks.

Undyne and Alphys were on the decorations while me and Sans were cooking. We were making spaghetti, since it's Papyrus' favourite. We're also gonna have chicken, burgers, hot dogs, pizza, cakes and so much more. We were making the spaghetti when my phone went off. I grabbed it and saw that Papyrus was phoning me. "Be quiet Sans." He nodded but I could tell he's up to something.

Papyrus {HUMAN, I WOULD LIKE TO KNOW, WHICH DO YOU PREFER? CHOCOLATE OR SWEETS?}
Me {I like both but you don't need to get me anythi-}

I was cut off by Sans kissing me.

Papyrus {HUMAN? HUMAN? ARE YOU STILL THERE?}

Sans pulled away from me with a smirk leaving me a blushing mess.

Me {Y,yes I'm here. But, but seriously, y,you don't need to get m,me anything Pap-Pap-}

Sans was tickling my sides and I was trying so hard not to laugh.

Papyrus {PAP PAP? I LIKE THAT NAME. I SHALL SEE YOU LATER HUMAN!}

With that the phone call ended. My face was bright red. I dropped the phone as Sans continued to tickle me and I screamed. I was laughing so badly and tears began to form. I fell to the floor but Sans continued to tickle me. He was laughing as well. Undyne and Alphys ran in but when they saw us Alphys simply shook her head while Undyne laughed.

An hour later and all the food was set out. "Alright fine, I won't tickle you again." Sans said in defeat which made me smile. Suddenly, he pulled me towards him and kissed me. "Never said no to kissing you though." He smirked making me blush. Everyone soon arrived except for Papyrus. "I see him!" Undyne yelled. We all got ready. When he opened the door everyone screamed "SURPRISE!" He gasped and smiled. "HUMAN! DID YOU DO THIS?" He asked and I nodded. "With help of course." I smiled. He picked me up and hugged me.

The party was great. Everyone was smiling and laughing. "Hey, Frisk?" I looked over to Sans. "Yeah what's up?" "I was thinking, since it's so much better with you here, maybe you'd want to move in?" I blinked. I saw his blush begin to grow. "T,toriel said it was all fine... if you want I mean it's your choice but-." I put a finger to his mouth. "I'd love that." I smiled. His smile widened and he pulled me in for a hug. "Let's stay together forever." He whispered into my ear. I blushed but nodded and smiled.
