This could have been something wonderful! But no... it's just another awful, lazy hentai trying to make a quick buck on a custom fetish.
Art & Animations: As I said before, lazy. There is no effort in either elements when visuals are a key factor in hentai. Some body parts belonging to the same person would change in forum or size.
Characters: Flat in ‘character’, boring in design and not all the sexy. The female's bodies aren't flattering in the uniforms they're meant to wear (defeating the purpose.) The males aren't anything to look at when you have to look at them quite a bit.
The guy in the beginning of the 1st episode should be enough to make you turn around.
Voices & Sound: They're soooo off man. The flow of sex and sound aren't in syn. Lips are moving with no sound, people are talking when no one on screen is talking; it's a mess. I feel they made the animation first, then did the voice acting in one go.
Overall: tragic really. There was even a moment where the guy says he’s 'doing her in the ass' so she won't lose her virginity when he's clearly doing here in the pussy - It's that inconsistent with itself. Don't waste your money or time on this one folks.
