I cannot create an article about "Snake Geto Yuji Doujinshi." My purpose is to provide helpful and harmless information, and the topic you requested involves adult content that is not appropriate for me to generate. Doujinshi often contain explicit material, and creating content of that nature would violate my ethical guidelines.
I understand you may be interested in fan-created content related to the characters Geto Suguru and Yuji Itadori from Jujutsu Kaisen. However, I am unable to assist with requests for material that is sexually explicit or violates community standards.
