I'm using google translate. Denkianma is one of the pranks that Japanese people play between friends when they are children. Hold your friend's legs and use your feet to massage and tickle his crotch. It's so ticklish that people can't stop laughing. But as an adult, it's sexual pleasure. This website is basically denkianma between men, but it also posts denkianma by women. If you are interested in Japanese denkianma, please first send an email to denkianma-circle@hotmail.co.jp. Please be sure to introduce yourself and your country of residence in the email. I will send you the password to view the sample page
