Visit any porn site, and you'll be bombarded by a video player collage of click-through body parts. Some of them have clear owners, and others are presented as if entirely independent of a larger musculoskeletal structure. Pairs of breasts here, there. Legs tangle in the lower right corner. A face surfaces, but only for the money shot.

So when spoken word artist Brenna Twohy tells you that she is an unabashed devotee of all things "Pottererotica" -- erotic fiction based in the magical universe of Harry Potter -- your response probably shouldn't be that her taste is "unrealistic." Given all of her options, erotica rooted in a fantasy book series actually seems the least fantastical.

"The sexiest part is knowing [the characters] are part of a bigger story, that they exist beyond eight minutes in 'Titty Titty Gangbang,' that their kegels are not the strongest thing about them," she explains in the video above, a clip of this month's National Poetry Slam uploaded by Button Poetry.

Unlike porn, Twohy's erotica comes grounded in a reality where women are strong, full-bodied people.

And where Hermione Granger and Ginny Weasley would quicker curse you with a Bat-Bogey Hex than take an insult lying down, a 2010 Violence Against Women study found that 90 percent of porn video content online and off included verbal or physical aggression towards women.

"I know a slaughterhouse when I see one," Twohy says of the porn industry. "It looks like 24/7 live streaming, reminding me that men are going to fuck me whether I like it or not, that there is one use for my mouth and it is not speaking, that a man is his most powerful when he's got a woman by the hair."

Twohy suggests that the "slaughterhouse," an uneasy analogy where the slicing instruments aren't knives but part of a video editing suite, does more than just provide shots of women's segmented body parts. It also creates a culture where domestic violence isn't only expected, but accepted.

And she's not having any of it.
