This is a great manga. The artwork is not the best i have seen but the story behind the drawings is really nice.
All the stories are based in sexy office girls (secretary,boss,...) being constantly having sex (straight sex, group sex, threesome, double penetrations, gang-raped and such alike things...)

Office Life is about a woman who seems to be the one running things in the building, and on top of that, she is also a nympho. She has countless sex partners here and there in the office she works at, and not to mention all the positions that she seems to love as well. This manga is vivid and straight to the point, and not to mention the art is well done.
