There’s not a lot of exciting ways to raise money for charity. Bake sales are fine and dandy, but there’s only a certain about of joy that can be derived from a brownie. However, one Japanese charity’s found an ingenious way to raise money: By letting guys touch women’s boobs.

Each year Stop!AIDS holds an event where men donate money for the opportunity to grope the assets of their favorite Japanese porn stars. It’s called “Boob Aid,” and it’s very effective. In 2014, 2000 guys showed up to cop a feel. The entire event is live streamed online, because apparently the nine porn stars would feel comfortable if their boobs were being touched and someone wasn’t filming it.

Here’s some of the pictures from the 2014 event:

If this event were held in America, it would probably raise a billion dollars.
