Role-playing goes hilariously wrong

Here’s a short video that I came across. It shows a couple role-playing. It starts off about like you’d expect, but things soon take a wrong turn. It’s sort of a modern equivalent of an O. Henry story.

Spoilered out of an abundance of caution–parts are probably mildly NSFW.

Is this role playing with pencils and dice? Or like sexual preversions? Either way, I’m not sure I can bring myself to watch it.
