She is a strict homeroom teacher at school and a kind, lewd mother at home.

My mother had two faces. They are "teachers who are strict about students" and "mothers who are sweet to their son." The "teacher" orders me, who is not good at studying, to stay, and gives a handjob to sermon in an empty classroom! However, my mother, who always smiles at home, loves me so I serve her kindly! I have no choice but to get tired of my dick being swayed by such a tsundere mother...
