You were there when sans said that new law in the underground about eating humans and the dark secret after that law is that the old sans you knew was gone and he would hurt you without anyone knowing so one day...... You ran away to your mother, Toriel, you helped her when it came to humans well some of them if the human was rude then you would not hesitate to kill them and suck there blood! (don't start to with 'ugh why would any reader want to act like that but think about it, if you were a actual character from horrortale you would probably be like this) But if they were nice then you would secretly help them leave the ruins.
Back when you were sans' girlfriend/slave/stress relever he forced you to wear things, now though you were some vampire like clothes that are comfortable.
One day, flowey came since he knows that you are nice to nice humans android you "(Y/N) there a human come quick!" And of you both went to were the humans fall, you saw a child that had had a long dress, unhealthy skin, brown shorts and short, brown hair, "Hey there are you ok?" You asked startling the human " hey hey it's ok I'm not like the other monster that eat others " you lied, your method was to trick the humans and if the h are rude you would suck there blood and kill them "a-are you a human?" The girl asked, this made you burst into laughing and for just a minute you looked like the happiest monster in the underground , "wow I have never been asked that, anyway no I'm not a human I'm a vampire but I won't hurt ya" you explained, she nodded while trying to hide that she was scared but failed due to her shaking " oh my" a familiar voice said startling you, flowey and the girl "(Y/N) I see you have found a human good job" mom said with a fake kind smile while patting your head as a way to say ' good work my child ' "I-I'm A-Aliza" Aliza stuttered "do not be afraid my child I am Toriel caretaker of the ruins and this is (Y/N) my daughter" Toriel said, you waved.
Timeskip because I am a lazy shit (Hey that rhymed)
Aliza was nice to you so you decided to help her
1.save flowey from being a burning crisp
2.save her from a human eating goat
You helped her down the stairs to the big door, you were about to open the door to let Aliza out but she stopped you by saying "could you please help me get though the underground and back home on the surface?" She asked, you smile gently ' poor kid if she goes on her own then she will definitely die out there ' "alright" you said, you were slightly scared to go out because of your past with sans but for the kids sake you would " but" you started while turning into a bat "I will be like this on your shoulder cause I have a bad past with the monsters so if things get to intense then I will help" you said while going on her shoulder "she nodded and pushed the doors open.

" HUMAN CROSS ON THIS BLUE ICE WITHOUT GOING AROUND IT SHOULD NOT BE TO HARD RIGHT" papyrus shouted 'on no' you thought, you know what blue ice can do. Aliza turned to you, you shake your head but there was no other way to solve the puzzle without going though the blue ice so Aliza did and she started to sink, you use your bat feet and tried to pull her up from her middle finger (fuck you) but you could not so the only thing you would do was look at flowey ,who was behind a tree, and have him a look that said 'reset ' (you know the resets deal with it) but he whispered that he can't, you heard him due to your super hearing and before you know it the world reset back to the first puzzle 'Aliza can reset ' you realized.
You holds up 3 fingers as to say she needs a freebie (clue) and papyrus carried me and her to the other side (sweet free piggyback), papyrus left and instantly sans pulled Alizas hair pulling her back and carrying you with her "hmmm blue ice in your hair yet you never touched the ice, a scare on your neck even though you can out of the ruins un harmed and little (Y/N) in her bar form even though I thought she died months ago " he said picking you up by the wing, you were scared, terrified even! Just remembering the things that sans did to you gave you a unpleasant chill down your spin (you feel your sins crawling on your back) you turned into your original form, pushing sans away to make him let go of you and Aliza and used your super speed to get you and Aliza away from him.
Time skip to grillbys (I feel lazy today)
The near dude said the story about what happened to sans which you thought was boring since you already know the story "now does anyone else want to tell a story ?" The near dude asked everyone said no " well then...... Let's eat! " everyone said the last part as someone grabbed you and grillby pulled Aliza to a grill and tried to cook her slow and painfully "mommmy!" She screamed, you got yourself out of the monster grip and pulled Aliza out of the grill and super speeded ( is that a word) out of grillbys and to a safe place that you know. You gently laid Aliza (that just sounds wrong in so may ways) on a bed "get some rest kid you deserve it" you said
"thank you" she mumbled we she drifted of to sleep (1004 words boi).
You walked out of the hide out to see if anyone followed you from grillbys. Suddenly, you were grabbed by the hair and a familiar voice whispered into your ear "did you really think you could escape from me baby doll?" Sans? 'oh no' you thought. Sans teleported to his room with you under him "let.me.go" you demanded
"No can do baby doll this is PUNishment for running away and leaving for years" he said while using his axe to rip your clothes of leaving in you nothing but a bra and panties. He started to bite your neck making you whimper in pain "s-stop" you begged, sans chuckled and pulled you towards him so your head was on his lap, he took of his shorts showing his dick and forced it in your mouth, you tried to pull away but he grabbed your head forcing you to take it all in . You cried in pain from the cock going down your throat while sans was moaning and groaning in pleasure.
He finally climaxed in your mouth and let go of your head so that you could pull away, you spit out the fun out of your mouth and tried to back away from sans (key word: tried) but he grabbed your hand and pinned you to the bed. He pinned you to the bed and started to pound into you, you weren 't a virgin so it did not hurt (he already took your virginity before)
Time skip
You both cummed and sans let go of you, "remember this sweetheart your mine and your not leaving me ever again" he demanded , he looked at your stomach to show a tiny monster soul, you were pregnant with sans' kid, sans seemed happy about this but you were the opposite, you had to admit you still love sans but you were scared about the childs life since now a day's the underground is not a good place to grow up, "can I at least see Aliza she's like a sister to me" you said you
" oh no need for that papyrus already brought her hear " sans answered
"Wait your not going t-"
"No we aren't going to hurt her or eat her ."
