I do not own Undertale only my oc

Who would have thought that the best way to win over your true love was to tell them stupid puns through a wall. After the barrier had been destroyed Sans had talked to Toriel on multiple occasions. After many dates Sans decided he wanted to show just how much Toriel meant to him. He was going to propose to her. He looked at the small ring that was sat in the black box the small ring was a small white skull on a silver ring the only problem was that he had no idea how he would even bring this up with her. Just then the door to Sans bedroom swung open and stood there was Frisk, the human who had freed all of the monsters and was now the adopted child of Toriel.

"Oh, hey there kiddo what's up?" Frisk sat next to Sans pointing to the box saying.

"your going to propose to mum, aren't you?" Sans' eyes widened in shock.

"How did ya know kid?" she just gave him a 'really' face.

"It's kinda obvious that you like mum" Sans sighed.

"I just don't know how to do it" Frisk thought for a second before saying.

"Well do it only the best way you can" With that Frisk left the room and a few minutes later Sans walked downstairs to see Toriel in the kitchen baking a pie when she saw Sans she smiled.

"ah hello Sans. Frisk has said that you wanted to talk to me" Sans looked to the kid who just smiled.

"oh, uh, yeah. Knock knock" Toriel rolled her eyes but spoke.

"Who's there?" Sans placed his hand in his pocket saying.

"Will"

"Will who?" Sans then pulled out the ring.

"Will you marry me?" Toriel gasped softly. She then sighed.

"Sans, Knock knock" Bad thoughts were running through Sans' head about rejection.

"W-who's there?"

"Y" Sans began to take sharper breaths.

"Y, who?" Toriel then smiled.

"Y,E,S. Yes!" Sans could feel the relief leave his body tears were now falling from his eyes. "Sans whats the matter?" Sans wiped some tears.

"I was just so scared you would say no" Toriel chuckled as she knelt down hugging Sans as he hugged her back. He then slipped the ring on her finger and they shared a kiss between each other. A few weeks later the big day had arrived Toriel had appointed Alphys, Undyne and Mettaton as her bridesmaids and Frisk as her flowergirl. The bridesmaids were wearing long purple dresses and Frisk wore the same style dress but she had a small basket with a large number of golden flowers that she would scatter. Sans had appointed Papyrus as his best man and Grillby as his groomsman the two both wore tuxes with black ties. Sans was wearing a black tux with a golden flower attached to him. He stood at the alter waiting when the music started up, looking down the aisle Frisk walked down the aisle throwing the flowers down the path. After which the bridesmaids walked down then finally Toriel walked down the aisle. The sight of Toriel nearly made Sans faint. She was wearing a long white silk dress with a long white veil and on top of her head was a crown of golden flowers. After the vows were done the shared their first kiss as a married couple. After which the two left Frisk with Papyrus so they could start their honeymoon when the two arrived at the house Toriel smiled and picked up Sans bridel style and carried him in the house.

Ten months later Toriel had become pregnent with Sans child when they told Frisk they were excited to have another sibling. On this day Toriel was sitting reading a book, Sans had gone out to the shop and Papyrus was in the kitchen. Suddenly a sharp pain filled Toriel's abdommen clutching her pregnent belly she took several sharp breaths before calling out.

"Papyrus I need some help!" Papyrus came running in.

"WHAT IS IT YOUR HIGHNESS?" Still clutching her stomach Toriel gasped out.

"I think it's time. The baby is coming" Papyrus gasped and quickly got Toriel to the hospital in his car he walked to the reception with Toriel saying.

"EXCUSE ME HUMAN MY FRIEND NEEDS SOME HELP IT IS HER BABY" the receptionist took one look at the goat before saying.

"no thank you. We do not take care of monsters here" Toriel was to much in pain right now but she needed help.

"What is wrong with you punk? Help her" Undyne had rushed there after Papyrus had called her. The receptionist glared.

"I don't think so you monsters don't belong here in the first place so I will not bring another freak into this world" From behind the shocked group a womans voice spoke up.

"Excuse me I don't think you have the right to say that" The woman was a doctor who was glaring at the receptionist. "If you will come with me,mam, I can take care of you" After the doctor,who was actually called Dr Lin, had settled Toriel in a room she examined her.

"Where is Sans?" Toriel asked worridly.

"HE SHOULD BE HERE SOON" At that point the door was slammed open and Sans ran in with Frisk he stood next to Toriel when Dr Lin spoke up.

"Okay it's time so can everyone, except the father, leave please" A few moments later a soft crying filled the room the happy couple looked at the small bundle in front of them. The doctors had told them weeks ago that they were due to have a baby had her mothers body with a small tail her head however was a goat skull with two small horns on top of her head. She also had a tuft of white fur in between her horns she also had two small goat ears her mouth was small and she had a set of sharp canines. The doctor wrapped the baby up and passed her over to her parents slowly the baby opened up their eyes they had a sparkling set of blue eyes. The couple smiled at the baby and after the family had awed at how cute she was they let Frisk sit next to Toriel and meet her new sibling. Holding her gently in her arms she hugged her new sister closer to her looking at her parents she asked.

"What's her name?" Toriel looked at Sans and answered.

"Her name's Anna"
