How to multi-thread a Session in NHibernate using MySQL for multiple requests?

I have implemented NHibernate using NInject MVC5 in my MVC C# application. All works well but i realized that when i double click on my links i always get the error(s): {"There is already an open DataReader associated with this Connection which must be closed first."}

or

{"Session is closed!\r\nObject name: 'ISession'."}

Now i know this is because im binding my IContentService interface to ISession. I also know that ISession is not thread-safe and can only be used once. So my question is... then how am i supposed to create a session that can be used simultaniously InRequestScope across multiple threads. Because i know users will double click or users will click a link at the same time another user is clicking the same link and errors that stop multiple users is not really ideal.

I have this in my injections:

 Bind<IContentService>().To<ContentService>().InRequestScope();

            Bind<ISession>() //I'm sure the problem is right here, but not sure.
               .ToMethod(
                   context =>
                       context.Kernel.Get<IMasterSessionSource>().GetSession())
               .WhenInjectedInto<IContentService>()
               .InRequestScope();

My ContentService

public interface IContentService
    {
        IQueryable<Question> Questions{ get; }
    }


 public class ContentService : IContentService
    {
        private readonly ISession _session; //I think the problem might be here too...

        public ContentService(ISession session)
        {
            _session = session;
        }

        public IQueryable<Question> Questions
        {
            get { return _session.Query<Question>(); }
        }
    }

UPDATE

I read how i should use ISessionFactory for multithreading but i was unable to bind it like i can ISession.
