A character willingly wanting to be consumed can be shown in many ways, such as...

• The prey expresses excitement about being eaten, asks to be eaten, offers themselves, or actively encourages the pred to consume them
• This includes prey pov where the pred is talking to viewer, and reacting to the viewer's explicit or implicit willingness to be eaten by them

• If the prey is visible, either before being consumed or through an internal, they may:
• Be shown as excited or happy, appear to be comfortable, they may be blushing or smiling
• Willing prey may have heart shaped eyes or pupils, or hearts emanating from them
• Show sexual arousal, looking pleasured, possibly with a wet pussy, or erection
• Be shown masturbating — see: masturbating prey
• Multiple prey may be shown lining up, willingly feeding themselves to a character
• Rarely, willing prey characters may be shown forcing themselves into an unwilling pred

• If the prey is not visible, willingness can be implied by:
• Dialogue that implies or explicitly states that the prey was consumed willingly (with no visible struggling or other evidence to imply otherwise)
• Hearts, smiley faces, or other pictographs shown emanating from the predator's body after consuming the prey
