In case you missed out on the short intro here it is :D
Story :
Jiraya had long petitioned for sexual education to be taught at in the academy so students would have knowledge about the topic prior to reaching adulthood. Everything was going smooth and well for the elderly sage until it's 2 days before class starts and he realized he has no sex ed "partner" to work with! He quickly runs from door to door across the neighborhood in search of his partner. Help him decide which he should bring in class!
