Below is a guide to creating an additional user account that runs off the existing PS Plus subscription. - Firstly create a new email account, I suggest your existing PSN ID as your email address - In PS Menu go to Power > Switch User > New User > Create New User > Accept > Next - Create New Playstation Network Account, Select Signup Now and fill in your details on the next 3 menus using the email address you just created. - Create Online ID - I Suggest using your existing PSN ID with _2 on the end. - Sign in & Verify your email. - Continue through the next few menus and skip when asked to create a PS Plus subscription. - Continue until you are in the PS Menu. You will now be able to go online with this account and your existing PS Plus Subscription.
