First of all, the art style is quite a mess. All of the characters have a very generic style, and the animation consists of something that is comparable to TV series that were being released at the time. Except it also has a bunch of unrealistic, gravity-defying boob physics. The backgrounds are decent, but nothing looks too particularly detailed aside from them, making the whole thing just seem incredibly average, especially compared to other OVAs from the time period.
When it comes to the story, this show is also not very watchable. Everything is done simply in service of getitng the characters into different sexual situations, and it quickly becomes incredibly boring. Let's put all of the sexual stuff aside for a moment. Even without all of that, most of the characters have zero depth to them and even the ones who have a little tiny bit of depth are still the most generic, cookie cutter archetypes that you can think of. This is compounded by the terribly cheesy dialogue and voice acting that plagues this entire show, making most of the characters immensely unlikable and forgettable.
The only character that I actually found somewhat endearing was Kirika Misono, but that was mostly because it became a running gag for her to surprise the main character from behind, crushing him with her boobs, any time she was being bossy or confronting him about something, and that always got a bit of a chuckle out of me.
I feel like that's probably the only decent part of this series, the gags. There were a few chuckles to be had here and there, but nothing that will make you laugh up a storm, and you also have to get through a bunch of other really poorly done stuff to get to those laughs, so it still makes it pretty difficult to recommend.
As an aside, the soundtrack was also incredibly unremarkable... so much so that I'm having trouble remembering if there even was a soundtrack at all (and I just finished this series, folks).
Overall, it's not the worst thing I've ever seen, but there are so many better shows that one could be spending their time with. Even if this show didn't have any sexual references or innuendo at all, it still wouldn't be good. That stuff doesn't help it at all, but it's not what makes this show bad. The show tends to fail on multiple levels, so even though there's a few redeeming qualities underneath, it's still not worth dragging yourself through all of the bad parts.
