Uchi No Otouto Maji De Dekainn

The manga and light novel (if applicable) can usually be found on various Japanese online marketplaces, bookstores, or through digital platforms such as BookWalker, Amazon Japan, and Rakuten.

Note: As this is an adult work (R18), it contains explicit sexual content and is intended strictly for mature audiences.

So a natural translation is:

"My little brother is seriously huge."

While it presents an interesting exploration of character psychology and complex relationships, its focus on taboo subjects may not appeal to everyone. Potential readers should be aware of the series' themes and consider their own sensitivities and perspectives before engaging with the story.
