It started off as a friendship, but ever since the elimination of Paintbrush in season 3, the two got closer to each other. Test Tube decided to run a Science Program in her free time. Paintbrush agreed to join in since the schedule is a day after Paintbrushes Art classes every week, and so did Fan!

TW ⚠️ Testbrush Its a Testbrush fan fiction so I don't know what you expected!!! Might update later if I change my mind idk Nothing sexual will be in this Fan-Fiction, just so you know because sexual stuff is ICKY!!!!!!! /imo And also it isn't humanized because that just makes me uncomfortable idk why 😀 And to my dearest allies, friends, buddies, pals, homies, companions and comrades. Don't judge me alright, it's my comfort ship. /SRS I also realized I made a couple mistakes in chapter 1, so you might need to reread it (sorry) 😖 ⚠️ THIS IS FOR FUN AND IT IS MY COMFORT SHIP THIS ISNT TO BE TAKEN TOO SERIOUSLY! ⚠️ All characters are owned by Animation Epic, and are not mine.
