UltSans was in his lab, organizing the human souls he had storaged. After he finished, he was bored again, but he didn't wanted to go train on his gym, or lose time as always does, so he started thinking.
After a while, he got the idea of playing some card games, or any table games. So he opened a portal while thinking in who to bring to play and what to play, and so, he opened a portal to a random AU, which was StoryShift.
UltSans hesitated, noticing StoryShift Chara going through the portal.
StoryShift Chara: "Oh, greetings~"
UltSans: "... Breh. For flirt I prefer the edgy you."
StoryShift Chara: "I can be edgy too~"
UltSans: "... Stop trying to break a fandom ship. I'm not interested, but... I accept sex here and there."
StoryShift Chara: "Good enough."
UltSans then opened a few portals, and few Sanses appeared. UnderFell, HorrorTale, UnderSwap, EpicTale, and X-Tale.
They all hesitated, but Cross and Epic went with their memes, while Blueberry had Horror under control by caressing his chin.
After a moment of organizing, UltSans prepared all for a good time of games, and a lot of snacks and drinks.
UnderFell: "Why the fuck we have to accept this?"
UltSans: "Oh, simple. Because I fucking say so."
UltSans said while giggling and half laughing, but doing so terribly bad.
StoryShift Chara: "Make appear my friend."
UltSans: "You have a friend?"
StoryShift Chara: "... Ouch. But yes, I do. It's Sans."
UnderFell Sans: "... I'm not your goddamn friend."
UnderSwap Sans: "I can be their friend if they want."
HorrorTale Sans: "I don't befriend food."
UltSans hesitated, with a surprised and shock expression.
UltSans: "... Dude, I know she's smashable, but don't be so... straight, aight?"
HorrorTale Sans: "What do you mean?"
UltSans: "Forget it."
Meanwhile, StoryShift Chara has a perverted expression while her face was shifting red.
StoryShift Chara: "Classic Sans? Original Sans?"
UltSans: "Oh, you mean your boyfriend."
StoryShift Chara: "IT'S NOT MY BOYFRIEND!!"
StoryShift Chara replied while blushing heavily and from her ears dropping smoke.
UltSans opened a portal, and Undertale Sans joined.
UltSans(Thought): "Aw, goddamit."
UltSans: "Sup, classic?"
Sans: "Yo, wassup."
After a big while, they played quite few games. Even UnderFell Sans, Undertale Sans, Cross, Epic, and UltSans, played to 'smash or pass', daring each other who would smash who. Horror remained careless, UnderSwap Sans was shocked and found it inappropriate, StoryShift Chara faked to be shock but was blushing while interested to see and hear, and Cross and Epic were the ones who were mainly daring each other and the others with memes and trolls to smash.
UnderSwap Sans: "Can you stop already? This type of behavior and joy is not acceptable for royal guardsmen. I, the magnificent Sans, will stop this."
They all hesitated for a second, sharing glances here and there.
UltSans: "Bro thinks he's a royal guard. L+ratio."
Cross: "Lol, way too much blue for the taste."
Epic: "Bruh, your monologue saddened my bruh, bruh. you're too young to be anything, bruh."
UnderFell Sans: "Lmao, Lmfao. Skill issue+begging+no life+dumb+too confident+idiot+free Exp+free kill+bonehead."
StoryShift Chara hugged Blueberry, placing his head over her falt chest, while caressing his head.
StoryShift Chara: "Don't mind them, you'll be magnificent."
UltSans: "Said the falt believer."
UnderFell Sans: "Imagine having no boobs, and still trying to do that. Lmfao."
UltSans: "Hey, wanna see her actually hot?"
UnderFell Sans: "You got no balls, bitch."
UltSans: "Aight, bet."
UltSans then took StoryShift Chara who pretended to be offended and in shock but was actually blushing desiring to be taken.
Horror remained eating snacks, Blueberry remained in shock with wide open mouth, Cross and Epic continued using memes and references of 'before and after' of how StoryShift Chara would look.
After a big while, Horror ate all the snacks while Blueberry tried to stop him from eating everything adn to share with the others. Then, UltSans came back.
UltSans: "Gentlemen. I'll present you, the new, in heat, hot as fuck... StoryShift Chara."
He then moved his arms as a presenter, and from the door, StoryShift Chara was wearing a very explicit black maid that was barely covering her body, and her chest was now XXL.
UnderFell Sans: "Lmao, could only make her boobs huge. But I like your selection."
UltSans: "I can't do miracles."
StoryShift Chara: "I can wish you one, or a pair~"
UltSans: "Bro... Later for a trio, ok?"
StoryShift Chara: "Sure, as long as you satisfy and fulfill~"
UnderSwap Sans: "Well, this was a good time and all. Time to go."
UnderFell Sans: "Uhm, sure... I wanna see the fucking. I want to see who fucks who, and better be real hard."
StoryShift Chara: "Wanna get fucked too, redbone?~"
Then, Horror grabbed UnderFell Sans, and then they all left. UltSans hesitated, surprised to see how UnderSwap Sans somehow managed to make Horror take UnderFell Sans back to UnderFell.
But then, StoryShift jumped over UltSans and started giving him love with kisses and touches to heat him.
UltSans: "Ayo, w-wait. U-uhm... Didn't you accept a trio?"
StoryShift Chara: "... Yes, but I prefer all for me~ I'm a thirsty and hungry woman~"
UltSans: "... Damn! Bye to the fandom ship of 'Sans x SS Chara'... Welp, you're hot, so... Meh, who cares. Give me a good ride."
She rode him, her butt cheeks clapping while her huge breasts bounced up and down. he hold her waist firmly, and stopped looking her breasts to place his face between them, and she grabbed his head to make his face be all between her breasts.
After a while, he stopped.
UltSans: "Wait, let me, uhhh... Just look."
She hesittaed, but he snapped his fingers, and all started shifting and glitching, and then it suddenly became a dark room with red crimson soft light everywhere, and full of sexual dresses, dolls, and toys.
StoryShift Chara: "Oh, so you have a female doll of Error and others? I didn't know you liked them~"
UltSans: "I don't personally, but you know how the fandom is. Every character is smashable, profanable, and can be sexualized. I was once draw in rule 34."
StoryShift Chara: "Oh, really?~ How it was?"
UltSans: "Excitant and hot."
StoryShift Chara: "Well, let's continue, shall we?~"
UltSans didn't had time to answer, as she asked but to continue yes or yes, and so, she continue the ride, but now with more extra joy by the sexual toys at her disposal.
After the ride, both remained laying down. Her right arm behind his neck, and her left arm over his chest.
UltSans: "Yeah... You know what? I got an idea."
StoryShift Chara: "Let's see, what's on your up head?"
UltSans: "... Breh, well... As you accepted a trio, despite you took entirely for your, how about I do a harem? After all, the more the better."
StoryShift Chara: "No, that's not really a good idea."
UltSans: "Yeah, I know. For me is great because more joy with more options."
UltSans then got up, and opened portals.
StoryShift Chara: "Wait, don't. Your dick is huge, but you can't handle a harem."
UltSans: "Watch me."
He then grabbed StoryFell Chara from behind, and grabbed her breasts quishing them, she hesitated surprised for a second, before she got dragged to the portal. She hesitated, and looked around while patting her head with her right hand.
There were quite few there, StoryShift Chara, StoryFell Chara, FellShift Gold Chara, AlterTale Toriel, AlterFell Toriel, FellShift Gold Toriel and FellShift Gold Muffet.
Then, all paused as UltSans broke the fourth wall by falling from the left, and hanging his left arm over the screen.
UltSans: "God, I love abusing of the fandom... I'm harder than HardTale Sans, I'm so hard, not even Goku can beat me or any girl could survive a round. For sure you wanna be with this harem, don't you?"
After a while, in the upstairs of the house, the hallway was expanded with an extra door at the left of the stairs, this door to the harem room, where was a big expanded and spacey room with personal bedrooms for each girl. AlterTale Toriel, AlterFell Toriel, and FellShift Gold Toriel, didn't had their bedrooms there, they had their own bedrooms in a new space in the gym.
When the girls were still getting used to the harem room, UltSans entered adn went to see FellShift Gold Muffet, as she called him for soemthing. The other girls hesitated, but decided to continue, while UltSans reached FellShift Gold Muffet's bedroom.
UltSans: "Alrigth, I'm here."
FellShift Gold Muffet: "Daddy, wanna try my new spider milk cider?"
UltSans: "ho oh! Dio! tutate piropara! YES, YES, YES, YES. YES!!!"
After a moment, by the sounds, StoryShift Chara opened the door, and the other girls peaked to see, and they found UltSans sucking FellShift Gold Muffet's nipples and breasts, while she was moaning of pleasure and joy.
UltSans: "Mmm, tasty. And I like is soft purple color, makes it feel like it has a Dusty reference~"
After a moment, the other girls heated up, so they also went to try, and it ended in hours of sex in an orgy.
After few hours, UltSans went to visit FellShift Gold Chara, as was the one who still didn't want anything like that, or be there. When UltSans entered her bedroom, she was sitting on her bed, with a red chain on her neck.
UltSans lifted his left hand, and open, the red chain faded in and he grabbed it as it moved to his hand.
UltSans: "So horny, and yet so stubborn... That's how I like my bitches to be, hard~"
ShiftFell Gold Chara ignored him, and simply remained careless and calm, letting him continue violating her. She enjoyed in secret, but didn't wanted to accept defeat like that, or that abuse from him was pleasurable or enjoyable.
Since that day, when he felt bored or in heat, he had guaranteed sex or an orgy to enjoy, even when any girl or girls felt bored or in heat too. When he trained, he did under guidance of FellShift Gold Toriel with the sexual motivation of AlterFell Toriel and AlterTale Toriel.
