Just to say that there will be a short break from lessons whilst we at Blackboards in Porn Towers stop looking at pornography for long enough to move to bigger premises. In the meantime, please do browse the archives.
Thank you to everyone for your comments and for sending in so many great images of blackboards in porn. We have been deluged with a shedload* of pornography, but hope to get through the backlog and posting reports again soon. It's a tough job, but somebody has to do it.
