cucumber using junit parallel execution is opening more #of browser sessions - selenium

Question

I have an automation framework using serenity bdd, cucumber and JUnit. I am trying to execute the test cases in parallel mode however I am seeing more #of browser sessions opening.
What I am looking for is open 5 browsers for 5 feature files, once this finish next 5 browsers should open for the next feature files but my execution is not happening like this.
In my case, i have 50 test cases in 50 different feature files and when I run the script 50 browsers are open. how to stop this? is there any setting I am missing in my pom.xml file?
