Dynamically fetch object fields from fieldset using apex salesforce

public static List<String> readFieldSet(String fieldSetName, String ObjectName)
{
    List<String> fieldsList = new List<String>();
    Map<String, Schema.SObjectType> GlobalDescribeMap = Schema.getGlobalDescribe();

    for(Schema.FieldSetMember fieldSetMemberObj : fieldSetObj.getFields())
    {

    }
    return fieldsList;
}
List<String> listfields = readFieldSet('CF_B2C_CustomerFields','CF_Customer__c');
system.debug(string.JOIN(listfields, ', ') );
