There is no necessary inference from a "direct relationship" that both increase and there is no inference that it is porportional. But it is often assumed that when someone says a direct relationship it is a positive movement, inverse meaning it is negatively correlated.

You don't know what you're talking about : the relationship, should one exist, between two sets can be defined as either direct or inverse. The cause of that relationship is statistically irrelevant. All relationships are proportional, be that 1:1, 2:1 or some function of defined parameters.
It's probably a good job you've not sought out studies as I'm not sure you'd be able to interpret the analysis.
