I think it is important to remember that we are talking about a manga that is supposed to make people laugh and not to think it could be something that could actually happen.
This said, i think the story is amazing. I liked particularly the amazing skills Akira has to create embarrassing situations. And I can't say a thing about the art, it is just perfect! All characters have personality and it is coherent along with the story. Also, you have physical appearances for all tastes, not just the classic ecchi with big breasts only (you have plenty of that though haha).
Anyways, I say is totally worth it, it will make you laugh - guaranteed!
