I've been debating whether or not to post this thing, but what the hell, you're all grown-ups.
Last time I was in Akihabara, I'd found a 7-story sex store filled with the usual DVDs, mags, fetish gear and cosplay outfits. After floor 2, my eyes just glazed over, senses overloaded. But you don't start hiking up Everest with the intent of half-assing, so I kept on going. On floor 5, I noticed what looked like a bright pink projector in the store window. But instead of a lens, the machine had a faux-flesh orifice with "Heaven" scrawled across the side. And instead of a lightbulb, it seemed to have a motor churning away, tirelessly. Then I noticed lots of disposable looking canisters around with different textured interiors. Aha, a bright pink japanese blowjob machine. Cool.
One geek thought occurred to me after the typical male ones: I bet this could be rigged into an automatic cellphone cleaning mechanism.
