Get the miso horny mug.
A modern variation of the traditional Japanese miso soup to which Spanish fly is added as an aphrodisiac.
When Keiko and I went to our favorite sushi restaurant for lunch last week, I encouraged her to try the miso-horny soup.

Less than two hours later, she was practically ripping my clothes off.
