This is dire. please help: My sister is in critical condition and declining and about to die and I need to travel right now to see if I can help save her life. I will do everything I can to help see a better life for her if I can just afford to make it there and stay with her. cash.app/$AngVon

he came back #underfell #cowboy #skeleton #papyrus

nopersona.itch.io/out-of-the-bag aaaaand it's up! I'm not tagging it with a proper announcement yet, because it's raw and still missing one puzzle, but the story is all there if you'd love to test it out c: (pls tell me if the in-browser version even working, I can't check it myself)

I'm bringing back a TRUE classic Undertale piece, now. Friendshipping by AyuOakhay. ❤️ It's so wholesome that it makes me scream. archiveofourown.org/works/5680993

I love how music brings stories back. This DNCE song just came up on my playlist, and I nearly forgot I wrote this classic 💙🧡 #fontcest piece to it. Funny how I remember my stories through the songs I had on repeat while writing them. archiveofourown.org/works/38023453

‪I'm glad that these two exist #fontcest #fellcest #papysans

Old piece of Edge on the edge 😌 #undertail #edge #fellpapyrus

My Digital Circus Smash or Pass list presented without comment

Edge couldn't hold in his desires anymore, and Red couldn't help but post it... It lead to some pretty favorable end results. (i had an idea from a picture and i couldn't stop myself) cw: incest, fontcest, fellcest

red on the mind

Fontcest confession fluff fic. Papyrus has been planning his confession ever since he and his brother settled into their new new home on the surface. He's planned everything perfectly. He knows the perfect place. He knows the perfect time. He knows the perfect activity!

<3

Okay okay, I believe in top/dom Papyrus supremacy, but COME ON! You can’t admit that this isn’t hot! A strong top deserves some love every once in a while (as well as some kink play~💖) #fellcest #fontcest #undertail #underfrick #daddykink

🦴💙 Live Laugh Bone 🧡🦴 #fontcest #utmv #horrorcest My art for the 2026 Fontcest Calendar Fanzine hosted by @livelaughbone! I drew the Horrortale bros enjoying an abandoned tunnel of love for Feburary! 🥰 Preorders open Jul 30 - Aug 27 at livelaughbone.bigcartel.com

You can't tell me Papyrus is not constantly fighting against cuteness aggression when it comes to Sans

time to sleep #undertale #fontcest #papysans #sanspapy #パピサン
