Joshikousei no Sukima

"An incredibly dangerous story of sexual lust between teachers and students!" My name is Ukishima... I'm a passionate, peace-loving teacher who was transferred to a girls' high school after a terrible experience at a boys' high school! By the way, aren't kids these days dangerous? Are they okay...? No, no, no, they're all perfectly polite and smart, the best, but there are some students who are dangerous in a slightly different sense... There are girls who keep sneaking into narrow gaps like corners of the road, corners of the garden, cleaning lockers, and the teacher's podium. ...And they're in heat!!
