Yes :) The prime example when it comes to spanking is probably "The Headmaster" which has it's punishment system in focus. Here the main character is also quite intelligent. The actual psychology of his explanations almost makes sense which is the reason I would not recommend this to too naive / young "players". It actually has a couple of quite emotional moments. Though not that many. Besides Cosy Cafe it's also one of the AVN I do support :)
Though be warned, many events are bound to certain days and there are a couple of events that require a certain order of actions that are not that obvious / easy to miss and you can get stuck. Though it has a great built-in "event archieve"
ps: In regards to That New Teacher, I think the concept of the "special guests" it brilliant :) Seeing characters from other AVNs in the story as a hommage and kinda advertisement is brilliant. Because of that I tried Stormside which also has a crazy story (though unfortunately it's abandoned)
