You're Ours! (Sans AUs X Reader)

Getting Pass by the skeletons

underfell and gastertale/Echotale.. are the dimension you didnt know... you didnt met them actually but you felt you met them... but you ignored it... you went to check at the skeletons they are sleeping... you kissed every sans at the forehead.. you know they will miss you...  prom is comming soon... in 2 or 1 days it will start... so you went to see chara

Chara and you met.. she dressed you up with boy clothes a sweater with hoodie.. a colored brown boots and a brown short.. your hair was a pageboy but curly.. you looked like a boy you thanked chara she said no problem you grinned.. but you remembered how can you think of an excuse... but they know your eye color so you shut down your eyes opening a little so you can see... you went back to the house...

''Sup kid.. this isnt your house..'' sans said.. thank goodness they didnt notice you

''im y/n's cousin... i want to meet her but she said... she wont come back for a while so she let me stay and guard you guys..ill be replacing her actually..'' you said it makes you sad seeing poor sans feel sad..

''welp kid let me show you around...'' sans said.. sans showed you around the house... the other sanses woke up as well... they were about to hurt you but sans said your y/ns cousin.. so they respect you.. 

A DAY PASSED

it was prom today the poor sanses dont have their dates.. so you decided to dress back to a girl... you went outside to change.. the sanses are asleep so you sneaked out.. suddenly you heard the sanses they want you back.. you said to them that you will never leave them.. their eyes glowed green.. suddenly underswap sans woked up

''human is that you?'' underswap said you nodded

''yeah its me'' you said

''HUMAN! we missed you! i will wake up the others! sanses! sanses!'' underswap sans said

''What the heck blue whats wrong?'' Underfell said

''Y/n is back!'' underswap said.. they hugged you...
