Auralism is a sexual fetish defined as sexual arousal or excitment caused by sound, to be compared with voyeurism. This sound might be music, a voice, the actual sounds of sex itself, or other sounds, and may include enjoyment from listening to others having sex. As with most fetishes, in some cases it is simply a small additional turn-on, and in others it is a requirement to sexual gratification.
Since the sound of her lover's voice in her ear made her groan with pleasure and get weak in the knees, he defined the word auralism just to describe her fetish, which until then, didn't seem to have a name.
An orgasm during anal penetration that originates in the center of the body and radiates throughout every nerve ending, creating a full-body orgasm lasting (but not limited to) up to 10 minutes. Though rare (like a unicorn, or a happily married couple), the analgasm is life altering and often sought after by sexual connoisseurs eager to please (or torture) their partners by sending them into an alternate reality that feels like a Dr. Suess movie, where good is bad and bad is good, up is down, and cats wear hats.
"She didn't know whether to laugh or cry during her incredibly long analgasm, but he was quite proud, either way."
