my older girlfriend "Ayaka" is beautiful, but has a very sadistic and masochistic personality. even in our usual sex life, she tends to torment me one-sidedly. i, who am masochistic, was addicted to her. one day, i saw her doing something forbidden with my boss. i never thought she would do something like that... strangely, i noticed that i was excited watching "that". i want to be treated like that too...
