Is it safe to access asp.net session variables through static properties of a static object?

Here is what I mean:

```
public static class SessionHelper
{
    public static int Age
    {
        get
        {
            return (int)HttpContext.Current.Session["Age"];
        }

        set
        {
            HttpContext.Current.Session["Age"] = value;
        }
    }

    public static string Name
    {
        get
        {
            return (string)HttpContext.Current.Session["Name"];
        }

        set
        {
            HttpContext.Current.Session["Name"] = value;
        }
    }
}

```

Is it possible that userA could access userB's session data this way?
