Another one of those "Only in Japan" stories:
"Fondling Breasts for a Good Cause
If super group AKB48 are idols you can see live on a daily basis, then Marshmallow 3D are idols you can cop a feel from.
Forget 3D boob games on the Nintendo 3DS! Later this month during a 24 hour telethon for an adult TV channel, you, me or anyone else can pay ¥1,000 (US$13) to fondle breasts five times. And this year, Time Out Tokyo reported, the breasts belong to idol group Marshmallow 3D."
