Sense Hoshuu Shiyo

I'm a new teacher at this school, overwhelmed with a mountain of work. My two students failed the term-end test, requiring remedial classes and retests. When called to the office, they begged to skip the process, citing loss of club activities and time with friends, and offered to do anything except for sex in return. Tempted but aware of the risks, I half-jokingly asked them for fellatio services instead. Surprisingly, they agreed, and our secret remedial sessions began. [Translated from DLsite]
