A Japanese celebrity midwife has invented a plastic boob rake she says can increase your bust size by up to three centimeters.  Takiko Shindo is known as the "Boob Goddess", thanks to a technique she calls "Oppai Taisou," or "boob exercise massage." While doctors are dubious to say the least, the idea is that regular massage stimulates the ligaments that hold up the breast and stops fats from settling in the muscles on the chest, causing breasts to sag. The plastic "Oppai Taisou Hand," retails online for around €46, promising "a convenient tool that anyone can use by themselves in their home."

"Being a full 22cm (8.7") in length, it can reach places that your hands just can't. And the unique shape and grip of the "hand" has been modeled on Takiko Shindo's actual hand, so you really are getting a personal massage from her."

Titillating. Here's a helpful demo to help you massage your mammaries like a master... fast forward to 1.52 to see an awkward model get the full treatment. https://www.youtube.com/watch?v=eZKX53H7hbg
