One might think that so many volumes in, the Girlvert franchise would be running a little low on creative vitality. Nothing could be further from the truth. Adding fresh layers of pathology to the title character's back story, this installment—which functions as a standalone feature requiring no familiarity with the series—brings our anti-heroine one step closer to essentially being the porn world's answer to Freddy Krueger or Jigsaw ... an iconic monster whose delight in doling out ever more cunningly grotesque tortures we all secretly share.

Ashley gets adopted in Girlvert 19 by loving couple Heidi Mayne and Evan Stone, who've been trying for years to replace the daughter Heidi lost at birth. They have two other kids already: Sonny Hicks, who immediately insults Ashley (bad move) and Sabrina Sweet, who's deaf. In Sonny's case, Ashley exacts her revenge indirectly by forcing his virgin girlfriend, Jennifer White, to submit to a relentless anal thrashing by him. (Classic Ashley Blue line, upon his initial puncturing of White's anus: "I don't want to sound weird or anything, but I just really love you right now.")

Sabrina's fate is decidedly worse: Ashley makes her give up her ass to Jenner as payment for a handgun. They both also assault her with a dildo attached to the business end of a miniature jackhammer.

And things just get more hellacious from there. This is a tremendous addition to the Girlvert canon that suffers only from sometimes blown-out audio and a bit of wood trouble in one of the scenes.
