Azure multiple VM with same Virtual Public IP and Host name mapped to Virtual Public IP

I am running following two VM's on Azure within same cloud service.

HOST NAME
First
PUBLIC VIRTUAL IP (VIP) ADDRESS
104.xx.xx.26
HOST NAME
Second
PUBLIC VIRTUAL IP (VIP) ADDRESS
104.xx.xx.26

On First nginx is running on port 80 and on Second no service is running on port 80

Now the question is :

I have mapped @ host name to above public IP(104.xx.xx.26). How would azure decide the VM the request to route to? Will azure route the request to Second VM where no service is running on port 80?

Update :

This Question is not related to load balancing! I just want all my http requests to be directed to First VM and that's the way its working now. My concern is how azure is routing the request. Can it route the request to second server some time, In that case response won't be serverd as no nginx is not running on Second Server. I will using second server for diffrent Services.

E.g. First Server will have Php,Nginx installed Second Server will have Mysql Installed

I want all the request on port 80 to be directed to first server.
