What I have understood from your post that Internet is working on S2 & you want to access internet on S1.
From configuration I saw that command IP routing has been configured on switch S1. You have to configure routing on both switches.
also post from both switches, show vlan brief command output.

There does have to be something in the mix to route between VLANs, the 3560 you have will do this job. You do not however have to enable routing on the other switch. You leave a lot out of your config, however when you create a connection between switches you have to create the trunk as you have done and you have to create a Switch Virtual Interface (SVI) for each VLAN you create in one of the switches. These SVIs will be created in S1 in your example since it is the switch with routing enabled, you only need to create one SVI on S2. That SVI will be the management VLAN.
I had a detailed discussion a couple of weeks ago, I'll refer you over to that discussion:

Edit: Here is a more detailed explanation of InterVLAN routing with multiple switches:
