This will be awesome!

I get why they wanted the masks now. It was a really cool scene. Hope the girls take them off when they kill themselves/each other though. More romantic that way.

I get what you mean by a middle ground between consent and non-consent. It's difficult for that to work for me, but a few authors have managed to get me to like that stuff. Kynk99, aka Erotic Kynk, was the best at it. At least in her case, it was when characters got into a mental space where the outside force was part of the sexual death experience for them. It tended to be because they were raped in the past, and wanted to relive the experience and die like they wanted to the first time.
