Tenga coffee tumbler makes Starbucks sexy again

Our favorite fashion designer of the moment, Gomi Hayakawa (of feast, the lingerie for flat-chested girls, fame), has come up with a great combination of two great things: Tenga and coffee.

She has come up with a “tumbler” in the Tenga onacup color — tongue in cheek, of course, and without official endorsement from either Tenga or Starbucks as far as we know.

Hayakawa shared her design idea via Twitter as an example of “Tenga merchandise for girls”.

Hayakawa, something of an intelligent-looking cutie herself, hasn’t yet made a prototype, it seems, though this is one tumbler we would very much like to see people sipping from at our local branch of Starbucks some day soon!

The only danger might be if you confuse a real, just-used onacup for the tumbler and get a milkier coffee than usual…
