"I'll whisper in your ear," "With me," "Come." Such killer phrases, foul play...!! I'm going blank from the pleasure of a man who's not my fiancé!! It's the regret of a love from 10 years ago. I'm fiancé, but I'm having a physical relationship with another man. No matter how good the two of us are, it's immoral to those around us. But I don't wish we'd never met. But if I have to let go of this happiness someday, I wish the world would just end right now...!! Including the title story, "Toy Volunteer: I want to be the woman you want to have sex with," "A Thousand and One Nights of Nighttime Companions," and "Falling in Love: We defy our destinies to pass each other by," a total of four forbidden and erotic love stories are included!! *This work is a re-edited version of a short story that was published in the magazines "Renai LoveMAX" and "Renai Cherry Pink," or distributed as a one-off.
