Kazuki and Tokiko have been dating for three years, but haven't had sex in months. The reason? Kazuki always finishes first, leaving Tokiko unsatisfied. So what does he do to fix this? He makes a promise to Tokiko that he will do whatever it takes to get her to finish first, and asks that they do whatever it is that she's always wanted to do...... Big mistake.
