School was close for the week buy it was okay i get to spend some time with papyrus dad was busy with his work in the lab so i was here with pap i made some milk for my brother i waited for it to heat up " gah aboo ra" i saw papy was playing with a couple of his toys it was cute after making his tea i give him it to drink after feeding him i let him fall asleep on my chest my eye socket were getting a little heavy and before i knew it i was fast asleep later when i woke paps was awake and playing with his toys saying random cute things i went over and watch him just to make sure his okay i close my eye socket just for a bit

A few moments later the phone rang "ugh five more minutes" i said not wanting to get up form my spot but pap made me get up by pushing me of his back " oof alright I'm up" i got an answer the phone still have awake"...
Mm hello" " s-sans now don't freak out but i need y-you to come h-here now" dad said he sound like something bad happened"d-dad whats wrong is everything okay" i had a little worry in my voice "j-just come" the phone hang up paps was still playing i got a bag and pack some baby food and some toys for papyrus i got my coat and put some warm clothes it was hard getting him in them he didn't like it but i got him in them we left our home and went off to see Daddy an hour later

After a long time we made it to the lab i open the door with one of my hands since I'm holding paps in the other it was quite too quite i kept walking until i met dr gaster " hello sans and is this papyrus" (gaster is a girl) " were is daddy* she went form happy to sad "you're dad he.... His test back fired and he's *sigh* he's dead" i felt tears in my eye socket

Gaster POV
" oh dear don't cry you'll make papyrus cry" i hug sans and rub his back to make him feel better he stop crying for a bit " hey look your not alone your dad allow me to take care of you two if anything happen" i said with a smile sans jump up giving me the biggest hug in his life

I pack up a few things and me papyrus and sans and we all went home happy

I want gaster to be a girl so deal with it
