The art was really good in this piece, and I would like to see a sequel. As for the plot, I would say that, while it was shallow, the art makes up for it in this case and a sequel could fill in the plot holes and make things more interesting by actually developing the characters' relationship.
The artwork is sublime in this doujin, but I do have to agree that it felt rushed a bit. I would very much like a follow up seeing how far he will take it with his boss.
