Oh Alphys, you’re so clumsy. Drew this in celebration for the Undertale Symphony. Great show! #undertail #underhertail #deltaruined #r34 #boobynude
Alphys on her knees blind in her lab with her lab coat exposing her butt, looking for her glasses that are right behind her. Alphys saying “Dang it! Where’d I drop my glasses?! Sorry King Asgore! This usually never happens! Ugh I’m so stupid…”. Asgore looking flustered and blushing, says “You’re ok Miss Alphys! I can assist you if needed!”
