Eclair Milk Cream -onani X Onani- [DIRECT]

Need to ensure that the story doesn't veer into explicit themes. Instead, focus on the craft, the personal challenges in pursuing perfection, and how he overcomes them. The title's wording might be a bit misleading, but the story should be wholesome. Maybe the "Onani" is a misspelling or mistranslation of "Onyx" or another element, but the user specified the exact title, so I have to work with that.
