Staring at this squishy little vibrator, that looks more like something you'd find on the beach than in a sex store, two thoughts went through my mind. The first was that I now understood what the seashells in Demolition Man were for. The second thought was perhaps more relevant to Tenga's Iroha Kushi: It is the perfect example of the rising trend of sex toys as art. It's the sex toy industry venturing past pure utility into art for art's sake, and it feels great humming against your clit.
