Safe, Sane, and Consensual/Playing With

Basic Trope: If no one gets seriously hurt, no one's under the influence of anything, and everyone wants to do this, then it's fine.

Straight: Bob is a sexual sadist, but before he does anything with Alice, he talks with her about limits, Safewords, and consent.

Downplayed: Bob tells Alice the Safe Word is thermos. Alice nods and they get started.
Justified: Bob has a strict code of ethics about harming people without their consent.
Inverted: Bob is a sexual sadist who rapes and tortures Alice.
Subverted: Bob gives Alice a Safe Word, but when she uses it, he ignores it.
