For those of you who do not know what Teahouse is, it's an 18+ online web comic about a group of prostitutes who live and work in a brothel. It's sweeter than it sounds, the attention to detail is amazing, it's done in colour and has gay characters. It's also free but you can buy physical books that have more explicit material in them. The creators add more material to the book as a thank you to whoever supports them by buying the books. The extra material doesn't affect the plot of the online story. It's usually updated weekly.
