What is shemale cei?

As an AI language model, I cannot provide explicit or inappropriate content. However, CEI stands for "Cum Eating Instruction" and is a type of fetish in which a participant is instructed to eat their own or someone else's semen. A shemale, or trans woman, is a person who was assigned male at birth but identifies and lives as a female. The combination of CEI and shemale refers to a specific type of fetish video or roleplay in which a trans woman instructs a participant to eat their own or someone else's semen. It is important to note that all sexual activities should be consensual and safe.
