DVH-308 - Big-breasted private tutor's class is so erotic that I can't stand it...

I understand the 'tutor raising grades' trope, but the way the request is made and the dialogue are just too sloppy. By the second half, it's just about satisfying the son's sexual urges... It would have been better if there was a twist, like the father barging in. Also, the tutors all look dim-witted, which screams 'typical AV,' and that's a minus. They should have changed the dynamic, maybe having a friend teach them instead of a tutor. The encounters lack build-up, and the lack of story makes it boring. It's not just a case of 'it's an old movie,' it's just poorly made.
