My understanding of the question:

you need someone to log in to access the site. now unless this guy logs off on one should be able to login and access the site.

If this is correct understanding then using session is perhaps not the right choice. use application to store the username. if the application["user"] is not null don't let anyone login and when the user logs off set this to null so that others can login.

Varushali,
You can try this:-

call 'getSingleLogin("UserName'")' Method Before Login Process.

void getSingleLogin(string username)
   {
       if (Cache["_users"] == null)
       {
           Hashtable ht = new Hashtable();
           ht.Add(username, Request.UserHostAddress + "~" + Session.SessionID);
           Cache["_users"] = ht;
       }
       else
       {
           Hashtable ht = (Hashtable)Cache["_users"];
           if (ht.Contains(username))
           {
               checkUserSession(username);
           }
           else
           {
               ht.Add(username, Request.UserHostAddress + "~" + Session.SessionID);
               Cache["_users"] = ht;
           }
       }
   }

C#

private void checkUserSession(string userDetails)
    {
        if (!string.IsNullOrEmpty(userDetails))
        {
            string str = ((Hashtable)(Cache["_users"]))[userDetails].ToString();
            string[] _str = str.Split('~');
            if (Request.UserHostAddress.Trim() != _str[0].Trim())
            {
                Session.Contents.Remove(_str[1]);
            }
        }
    }
