We need to have more teacher-student relationships like this, then only can we achieve a learning environment where either parties (teachers and students) are at ease in interacting with each other. Unnecessary phobias surrounding education need to be mitigated and interpersonal bonds need to get stronger as much as possible, the best example of which is this duo itself. It's commendable for the student to have the knowledge of inclusive endeavours like that of gangbang, threesome, etc. as well as about the necessity of not wasting even a single drop of cum i.e. the partner drinking it all.
