Saimin Seishidou Shota-kun!

Miyazaki Nagi. A ordinary high schooler who wanted nothing more than a normal life. He lives with a single mother and two daughters who he sees them as his sisters, but they're quite clingy towards him and always tried to do something "naughty" on him, which he was unaware.

However his so called normal came to a change, when he was assigned by the government as a...sex instructor?!

To bad that Miyazaki was to innocent and lacks of sexual knowledge since he was to embarrassed on how sex works. And that is why the government choose him as a perfect candidate as an instructor since they wouldn't entrust to someone who would've abuse it for their corrupted desire.

So with no other choice left, he decided to take this job and try to do his best to help those teens to follow the right path.

But unbeknownst to him...he would attract the attention of many females in his life, and their only purpose...is to corrupt him.

I don't own this "H-anime", the credit belongs to Tatsumi, Hirohiko and artist Aiue, Oka
