Willow sans/side chapter

outer sans pov

everyone has been asking me since when did me and Luna start dating. well since fell cheated on her which was 500 years ago. and yes those years did go by very quickly. then the week after that she asked me out and i said yes clearly and 40 years later we got married and360 years later and so now 50 days after giving birth to Willow she died cause she was killed.  

but it turns out that Willow was born with very unique eyes that only me and her have. the eyes are called galaxy eyes. their power is to allow us to use the galaxy as a ultimate weapon.  but Luna never the galaxy as being something useful. but she only learnt that after Willow was born.

but Willow wasn't always smart. most of the time she would write letters up-side down and would have to look at a mirror just to read it. when she started school by yours truly, she couldn't see a basic shape like a square or a triangle. so i took her to science sans and he said that she had dyslexia which was quite rare in the family. 

"welp, wait can't Willow be treated for this condition?" i asked science but he said no cause the treatment only works on humans so Willow was going to have a shit life i thought. but reaper helped her get better but the sad thing is that Luna never accepted Willow to be her daughter. that's why when Willow saw reaper for the first time she called him papa which was cute. but something was off cause me and Luna hadn't had sex yet and somehow willow appeared in our home and reaper said "yo outer. i think Luna isn't the mother to this kiddo." 

and later after that science sans took a blood sample of willow to find out her  parents. and the results were........... 

FATHER: OUTER SANS

MOTHER: KILLER SANS

"well did you have an affair outer?" reaper asked and i said "look i left killer but i didn't know that he was pregnant." reaper understood luckily but science was just like bruh why this kid needs halp badly. but Willow needed me so i left the lab with her, so she can finally meet her true mother. "dad where are we going?" she asked and i said "look sweetheart Luna wasn't your real mother but someone else is ok." and she was fine with that. im glad she is a easy kid to look after.  though Nightmare thinks that she has a great power in her that no other sans has. 

"what is it outer? you're normally not here." Nightmare asked and i said "look we just need killer so Willow can meet her mother." nightmare got off his throne in shock. "but i thought Luna was her mother. Cause Luna was pregnant right?" nightmare said and i told him that yes Luna was pregnant but she took an abortion due to her weight and she wanted to stay as she is. and she did want kids but it turns out she never really loved me after all. 

"geez sorry outer. but killer is in his room upstairs." nightmare said and i went upstairs and looked for killer.

i wait in my room before there was a knock on the door. "hmm? who is it?" i asked and they said "it's me outer and i've got important news to tell you." i allowed him inside but im not mad at him its just that we broke off due to me working with nightmare and i didn't want him to always worry about me. "so what is it outer~?" i asked him and hearts appeared in my eye sockets.  outer was blushing a little and said "you have a daughter." my eyes widened. i have a kid? oh now i remember. "where is she then outer?" "she's right here." she looked like a mix of me and outer which was very cute.

"well then shall we get back together then. so she can have a better life. and outer another thing since we broke up years ago, i wanted you back. my life was lonely since you left me. can we plz go back to the way it was?" i asked him and he said "after we end 404 for good cause now he's after Willow cause of her great powers." wait 404 is after my precious girl?! i'll make sure that the bastard never lays a hand on my outer and Willow that's a oath i will always make sure i keep. "but first things first outer doll~" i said and i kissed his cheeks and left to tell nightmare about 404 and his new plan.

after killer kissed me on the cheek i blushed. "daddy what's happening to mommy?" Willow asked and i told her "it's okay. he's making sure that you are going to be safe." the she ran off to look for her mother. oh dear she is a mama's girl that's for sure. "Willow! wait for dad please." i said and she stopped and her eyes looked souless. "he's here dad." she said and my curiousty was open "who's here Willow?" and then she turned around and said "king multiverse is here." wait why is he here? is he here to see Willow condersing he is her godfather.

"Oh, king multiverse what are you doing here?" i asked him and he said, "I'm here to see Willow about her powers and I'm here to give an update on 404's plan." wait 404 hasn't given up on my kid huh? well then ima go kill that bastard later but we need to find dust and y/n. they sure taking a long time.

"oi y/n! where are you?" i asked them to hope for a response. "dusty! im in horror's room chained up along with sinner." wait how did she end up in horror's room when horror isnt in the castle, how odd. "alright im coming in." i said to let her know but i feel a cold presence behind me. "what's going on here?" omnipotent said and i said "oh omni y/n got stuck in there along with sinner."

then we managed to get her out by luck. "y/n i have something to confess." i said to her and they were blushing, how cute of them. "what is it dusty?" they asked and i went in for the kiss. and i said "will you be my girlfriend?" i asked them and they said yes but omni said "geez you two. go make out in the bedroom." "you do the same thing with king multiverse." i knew i got him there.
