Nine Japanese porn stars have raised thousands for Aids prevention by letting people squeeze their boobs.
More than 4,100 pairs of hands groped the women for 12 hours, according to Channel News Asia.
It suggests around $40,000 was raised, as each participant was expected to donate $10.
Before the event, which was televised live on a Japanese adult channel, porn star Rina Serina told the Tokyo Sports newspaper: “I’m really looking forward to lots of people fondling my boobs.
“But I would be very happy if you would please be delicate. I never thought my boobs could contribute to society.”
Fellow participant Iku Sakuragi, 21, said: “It’s for charity. Squeeze them, donate money – let’s be happy.”
Fans are said to have sprayed their hands with disinfectant before groping the women’s breasts.
One man was seen pressing his palms together as though praying before and after he touched each of the nine women.
The predominantly male crowd also had female attendees, prompting one of the porn stars to say: “Wow, I’m happy. I want her to touch my breasts.”
‘Boob Aid’ was part of a 24-hour Stop! AIDS campaign event, which has been running since 2003, and is backed by the Japan Foundation for Aids prevention.
It follows the recent sexist heckling of a Tokyo assemblywoman, who was asked ‘why don’t you get married’ during an official debate.
Japan’s Prime Minister Shinzo Abe was forced to apologise for the comments which raised questions about gender equality in Japan.
