"I, THE GREAT PAPYRUS, WILL SURPRISE FRISK WITH THE MOST SPECIAL OF BIRTHDAY SURPRISES!" Papyrus yelled to sans, even though he was not two feet away. "Good thing you want to do all this, I'm to busy keeping control of the couch" sans lays on the couch, not moving. "IT WOULD BE NICE TO HAVE SOME HELP" papyrus goes back to hanging up the decorations over her door. It was frisk's birthday! She was out running errands with undyne and alphys, so they didn't have to worry about them coming home. It's her 16th birthday after all, the day she becomes a women! Or at least that's what alphys told papyrus anyway. Maybe she just reads to many anime... Anyway! Papyrus was almost done with hanging the banner that said "HAPPY BIRTHDAY HUMAN" in huge letters across hall, when there was a knock on the door. "SANS COULD YOU PLEASE SEE WHO IT IS?" "Sure pap." Sans grudgingly walks to the door and opens it, seeing frisk. "Oh hay kid, what are you doing home so early?" Seeing her wet clothes, he knew why "alphys thought that undyne couldn't through me from the end of the trail into the waterfall. She was wrong. Do you mind if I change?" "Oh...not at all. Here I'll get you some fresh clothes" "thanks sans." "No problem kid" sans walks into his room and grabs a pair of old shorts and a shirt he bought that was to small. He runs back to frisk "here kid. Go change in the bathroom. The one down here" he points to a room just to he right. "Thanks" frisk walks into the room and starts to take her clothes off. Thank god he had an extra pair of clothes. Their was also a shower, so she decided to take a quick one. She leaves her wet clothes on the ground, putting her dry ones on the shelf by the sink. "Hay kid, could you hurry it up in their? I kinda need to use it" "just come in. I'm in the shower." The glass was frosted, so all he would be able to see was a very blurred outline of frisk's body. "You sure kid?" "Yeah. It's not the first time you've seen me like this. Remember the beach?" One day when frisk, sans, and papyrus went to the beach, frisk jumped into the water from a deck, not knowing her swimsuit was to big, it it floated to the top without her. She swam to the surface, but then quickly covered herself as sans had turned to watch her dive. They both blushed as she grab her suit and put it back on. "Ok. I'm coming in" sans opened the door, trying to look away from frisk as much as possible, but failing terribly. Turns out the glass was old, and the frost had slowly withered away. It was now just glass, which frisk was to busy washing her hair to see. "O-Oh kid... The glass" he stutters out more words she doesn't understand, but then frisk saw the glass "oh sans, sorry!" She covers herself, then slowly puts her hands down "sans, if I'm going to live with you guys, we need to be able to use the only bathroom in the house at the same time." Sans looks away "still... M-maybe we can fix the glass kid..." Sans starts to blush "if it bothers you I can leave." "N-no it's f-fine" sans grabs a jacket from the hook, then puts her cloths in the dryer "sans?" "Y-Yeah k-kid?" "are you busy? I was wondering if you wanted to join me" sans starts to blush, then covers his face with his jacket, which has some paint on it "k-kid! W-" but frisk pulled him in, getting his clothes wet "kid! You didn't let me finish! Why?" "I haven't been able to be with anyone in so long" she was right. Frisk had been living alone in the inn in snowdin for weeks. It's was always cold and lonely their, and she often just stayed in her room alone all day. "What do you mean? "Be with"?" "I mean I'm very lonely all the time, and I haven't talked to anyone since I started staying in snowdin. It was a surprise when you called and asked if I wanted to stay with you." Sans starts to take off his clothes, throwing them into the dryer. They stand in the shower for a while, just looking into each other's eyes. Then sans asks "if your thinking what I thin your thinking, I know it's weird I don't have anything." He could see her eyes wondering down from time to time "and yes, I can if I try" frisk looks at sans confused "magic" frisk looks at sans, thinking about how he could be so calm right now "ok then, show me." She starts to kiss him, as his eyes glow a bright blue color. Almost right after, a blue shaft of light appears where is genitals should be, forming into the shape of a penis. "Woah! That is some crazy monster magic" "kid? Are you sure about this?" She puts her hands on his newly created member "I'm sure" she starts to stroke it, turning up the heat of the water with her free hand. Sans moans in response. Frisk starts to rub her own already wet cavern. She knows it's not just from the shower. She stops stroking and gets ready for his shaft "are you ready sans?" "Are you?" With that he slams into frisk, making her yell out in pain "keep it down kid, papyrus is gonna here us" "ok" he waits a second before starting to move back and forth at a slow pace. He then gets faster and faster as frisk feels something happening inside her. She feels her stomach start to tense. A knot forms in her, making her feel weird. But sans keeps speeding up, until neither of them can take it anymore and they both moan each other's names. Frisk can feel sans inside her now, even though he has already removed the glowing member from her body and it disappears. He steps out of the shower, not saying a word. Frisk stops him "sans. I love you." She whispers in his ear. "I love you to kid." He then puts his clothes back on and walks out of the bathroom. Frisk soon finishes her shower and puts on the clothes he spared for her. She steps out of the room, still drying her hair when-" SURPRISE!" She almost fell to the ground when she heard all the monster she had come to know where here. She had thought that only undyne and alphys remembered her birthday. She even saw sans, even though he was way in the back blushing like crazy. "Thank you guys so much!" Frisk runs forward and hugs everybody. Except she couldn't find sans anywhere. She look worried when someone tapped on her shoulder. "Hay kid. Didn't meant to run off like that, just needed to get everything ready. Sorry i didn't tell you. I wanted t-" she cut him off with a kiss. "BROTHER! I WAS THINKING ABOUT GIVING FRISK THE CAKE SOON HAVE YOU SEEN HER ANY WHE-OH... SORRY." Papyrus had candles in his hands and was going to hand one to sans when he saw what they where doing and he turned around and walked away. "Pap wait!" Sans broke away from the kiss and followed his brother. Frisk went to go sit on the couch when alphys walked over and say next to her. "H-hay frisk...h-happy birthday... I got you this." Alphys thrust a give into frisk's hands and then got up and walked away, not enjoying the amount of people at the party. Frisk opens the gift. It's the box set of mew mew kissie cutie. Frisk try's to find alphys to thank her, but she seems to have left. "Hay punk! Happy birthday. Got you somethin'." Undyne also gives her a present. It seems to be wrapped poorly, covered in scraps of paper and tape. Frisk opens it. It's an inflatable dummy. "Thanks undyne" she says as she hugs her "it's no problem punk" she tussles your hair, then walks out to catch up with alphys. "HUMAN! I, THE GREAT PAPYRUS, HAVE GOTTEN YOU SOMETHING AS WELL" he puts something into frisks hands. She opens it to find it is full of spaghetti. "DO YOU LIKE IT?" "Of course papyrus." She takes a bit and its really good. "I'll save some for later" she puts it on the table, next to the other presents she has gotten, and then walks up stairs. She passes by sans room to find him crying into his pillow. "SANS OH MY GOD ARE YOU OK?" Frisk runs into his room, to see what was open on his laptop. It was a page on monster anatomy. It states "only some monsters can impregnate humans. Among these are fire, fish, lizard, and skeleton categories." Sans sits up as she read it out loud, seeing he is actually smiling. Frisk was already crying tears of joy. He sits up and hugs her, making her shutter out of the coldness of his bones. It was freezing in this room. And also very dark. Both of them cried for a while, then start to laugh. Frisk was very confused at how she was feeling. She felt sad and happy and things she couldn't even begin to describe. She kissed sans. He kissed back. Sans got up and closed his laptop, then left. Frisk cover herself with a blanket, and went to sleep. Later that day, people started to worry about frisk not being at her own party. "FRISK ARE YOU OK?" she look around, forgetting she was at her own party! "oh sorry papyrus! I'll be down In second!" She finishes the party normally, not seeing sans the rest of the night. When everybody leaves, frisk turn to papyrus "have you seen sans anywhere?" "YES. HE LEFT TO GRAB SOME BURGERS A WHILE AGO. I WONDER WHATS TAKING HIM SO LONG" just then sans walks in. "Oh hay kid. Sorry I took so long. I got you these" sans pulls out a burger and fries from the bag he was holding "thanks sans, but I'm still full from earlier." "I'll just keep em in the fridge" sans then puts the burgers in the fridge. "GOOD NIGHT HUMAN! GOOD NIGHT SANS!" Papyrus walls to his room and goes to sleep. "Come on kid. Let's go to bed" he grabs frisks hand and pulls her into his room. They both fall a sleep on his bed.
