School used to be so much fun for Professor Jotaro Saruwatari, or Professor Jo as they called him back in the good old days. That, however, is no longer the case, not since the Principle got sick and the Fearful Fivesome took over. Now the school is being run by five very horny and power obsessed women who rule the school with an iron fist and open legs. Unfortunately for Professor Jo, he just doesn’t fit their idea of a good teacher, not with his constant apologizing to students and thus losing their respect. It was bad enough when they just ridiculed him all the time but now, after another one of his flubs, he is being forced to give up his class while he learns how real teachers operate. Suffice to say, this is just too much for Professor Jo to take, for even he has some level of pride. So he decides to do what any self respecting man would, he’s going to humiliate them right back with his video camera, Rapeman mask and the power of his penis!
This whole sordid plan of his doesn’t start off too well though. After stalking and raping Marimo, a female student he thought was snitching on him, he soon finds out she was just following him around because she likes him… Poor Professor Jo, he just can’t seem to do anything right. But that’s ok, she isn’t too broken up about having been raped and deflowered in a public restroom of all places, so she decides to help him exact his revenge. He is also helped, oddly enough, by all the teachers he is trying to blackmail. Rather than having to videotape himself raping them and threatening to make the videos public, all of these women are already involved in clandestine sexual acts with their students. A fact Professor Jo can’t help but exploit.
From there it’s about what you’d expect. Professor Jo picks a teacher to go after, finds her doing something she shouldn’t, and video tapes it. One teacher gets so hot thinking about being a stewardess that she uses a vibrator on herself while Marimo gives it to her with a strap-on. Another teacher is having sex with the male swim team, covering herself in their semen to keep her skin young and beautiful. And two of the teachers are caught using a student as their own personal plaything to spice up their own love life. After Professor Jo catches them doing these reprehensible things he’s not just going to hold the video footage over their heads for nothing. He proceeds to have sex with them all, often pulling in Marimo to help him with his devious sexual desires.
This is usually when the acts start to get a bit more extreme. With various toys, a bit of bondage and a Shop Vac, it’s no wonder all these women can’t stop pissing all over them place from the pleasure he brings. The only odd part about it is that Sextra Credit doesn’t really end. He hits four of the five women, gets the last one on tape having sex with a student, as per usual, and then just says he will have a talk with her tomorrow and that’s it. After two episodes of blackmail sex and mischievous acts, it was quite strange from them to simply switch things up and take a more mature tone. Though, since Professor Jo never went totally insane with his sexual lust, I suppose it did fit even if it shortchanged us one encounter.
If you’re going to have a hentai title that’s filled with blackmail and light sexual torture, you really can’t go wrong with making the women at least somewhat deserve it. That alone made Sextra Credit a much more enjoyable watch than it otherwise would have been, while the lascivious sex scenes and decent animation did the rest.
