An interesting way to go about this would be through revelation

The rule is "no adult content"

1 A scholar is discussing their recently published contribution

2 as a professional sexologist

3 whose area of study is pornography

4 Ancient pornography

5 And how it relates to modern styles

6 of fiction literature and paintings

7 by quoting seedy passages of ancient erotic literate

8 written in ancient Sumerian

Etc... With every sentence fragment of increasing context you can get people changing their minds
