~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-normally papyrus is the first to find out-

-it normally takes sans almost till the last day till he realises-

-but the reason for that is because of his job and trying to be apart of the royal guard-

-the first time you started your period they thought that frisk did something to you-

#overprotectivebrothers

-Papy will cater to your EVERY need, and act like your made of glass-
(Though he dose know you can take care of yourself, he just doesn't want anything bad to happen to you)

-you and sans will play as princess and knight, like you two would when yall were younger-
(And if you don't wanna do that it's fine he'll understand)

-Both of them are always prepared for when you start, they has a calender ready, they get you snacks, warm blankets, and everything else you need-

-Did I mention they love you?-

-Sans will ask the used to be star sanses(dream,ink, and ut frisk) to hang out with you both and have the time of you heaking life-

-But literally, both of them are SO caring when you one your monthly to the point where it seems that they want something-

-Asgore forbid if they see a speck of blood on your bed-

-All hell will be loose-

-I'm not going to explain what will happen, it's to terrifying to say-
