this is what i thought but it feels weird because with elasticity your hole should be virginally tight but that doesn't mean you'd have the same problem taking a larger cock that a virign would because your hole is designed to stretch more than a normal one. So a scene for something with an elastic hole should be different from someone with a tight hole (the gaping hole shouldn't be used because if its elastic it should snap back right?)
Its just something i'm toying with at the moment anyway since a commissioner brought up the issue
The rule of thumb is to use the looseness rating, not capacity when talking about and determining tightness. If you're looking for a parser to determine whether the hole gets stretched (if, for example, you want to talk about how stretched someone's hole is left afterwards, for a significant amount of time) then you use capacity. Also, there's definitely a command that forces stretching regardless of capacity if you find it absolutely integral to the scene, as Cerise has a scene that stretches all of your holes regardless of capacity.
I'm not sure what the issue is here. A super, super elastic hole would always be virginal tight, regardless of the size of cock (or other object) put in it, whether it's a 3 incher or two feet long, and would be described as such. That's what elasticity is all about.
