Tenga Onacup masturbation aid Halloween costume spotted in Shibuya on October 31st

And the award for best Halloween costume goes to… this guy dressed up as a Tenga onacup.

He was spotted among the thousands of other Halloween cosplayers out and about on the streets of Shibuya on October 31st.

In the Tokyo Kinky scheme of things, this is the best kind of Halloween costume imaginable.

There were actually three guys around the city dressed up as various examples of Tenga onacup masturbation aids.

Of course, there were plenty of scantily dressed teenaged girls too. They come close runners-up in our competition!

Foreigners have been known to try out Tenga cosplay too. Back in 2009 this chap in the States had a go and the results were impressive.
