"You've got guts, getting fully erect even though you're being scolded!!" A strict teacher uses the whip of love [scolding dirty talk] on a stupid student who has no confidence in his dick. He makes him hard with a nasty oral attack, and trains his dick with oral violence such as vacuum suction, deep throat, high-speed tongue entanglement, and self-fellatio. At the end, he rewards him by spilling semen in his mouth and swallowing it!! Furthermore, for students who suffer from premature ejaculation and those with excellent grades, he escalates the training to swallowing the dick whole with both his upper and lower mouths!!
