More than 8,600 people have signed an online petition to protest the annual Boob Aid fundraising event, which allows donors to the charity to touch the breasts of porn actresses.

Broadcast live on satellite network Sky PerfecTV!'s adult pay channel, the two-day event, held last month, is aimed at eradicating AIDS and has been held since 2003.

A record 7,175 people participated in the most recent event, raking in a little over ¥6 million. Participants need to be 18 years or older, and each year a few women can be found among the men waiting in line.
