This disc is a veritable lost ark for anal addicts. The reliable boys at The Ass Factory trot out four limber anuses one after another and stretch their limits. This ain’t the kind of workout a girl walks into cold. Reaming like this takes some bowel flushing and a night with a lucky butt-fluffer—one of the perks of dating a porn star. Blond beauty Sheena Shaw brings her lovely alabaster booty to the party, soaps it up in a hot tub, then gets royally reamed and piledriven until her shit chute gapes like the Carlsbad Caverns. You won’t believe it’s the same chick who did that cute little caboose shake at the beginning. Melina Mason’s generous mounds are built to tit-fuck, but it turns out she’s a tightass. She winces all the way through her backend workout. Positively heartwarming. The notoriously untamed Skin Diamond rolls onto the screen next and blows a hole in it with a jawdropping, spit-drenched gag session, followed by one of the hottest double-penetration scenes in recent memory. Check out our intimate portrait of the multifaceted Diamond in World of Sex. Skin can’t be bested, but the flick’s finale with freckle-faced Remy LaCroix and her virginal bubble butt has a tender, breaking-in-the-filly charm to it. According to legend, Indiana Jones went through hell to find this treasure. Now we know why.
