spread anus

post #3909789 post #3960749

When a character's anus is visibly stretched and/or held open by spreading, usually also involves spreading the buttocks. A character spreading their own anus may be presenting it, or inviting a character or the viewer to engage in some sort of anal activity with them.

Not to be confused with gaping_anus
Gaping anus describes an anus that is "wide open", usually without any spreading, typically after some sort of anal penetration (with a penis or sex toy).
