A Lesson in Shapes

This is what you get for trying to fit the round peg in the square hole.

This was commissioned by Undertaker33 and is based around a part of his story "Itsuki’s Substitution", centered around a very large Itsuki Nakano from Quintessential Quintuplets.

Check it out on his DeviantArt to read the first part of the story:
