This porn video tag is composed of several elements:
1. "Trans": This refers to transgender individuals or content involving gender transitions.
2. "FTM" (Female-to-Male): This term specifically refers to the process or experience of a person assigned female at birth transitioning to male.
3. "Creampie": A sexual act where cum is ejaculated into the vagina or anus, filling it and creating a visually dramatic scene in a porn video.
So, this tag indicates that the porn video features a transgender FTM individual receiving a creampie, meaning that they are engaging in sex with another person (often male) who ejaculates inside them. This type of content is typically appealing to audiences interested in gender transition themes and sexual acts involving cum.
