When an adult movie as sexually progressive and intense as Buttwoman vs. Slutowman hits the market, experienced viewers will see that there’s a fine line between sexual acrobatics just for the sake of it and real human sexuality being pushed to its limits. Sometimes just a look at someone’s face tells the whole story. In this dual starring vehicle for the latest incarnations of the Elegant Angel superhero characters Buttwoman (Alexis Texas) and Slutwoman (Kristina Rose), the pure, natural erotic passion of these porn superstars carries what could have been a merely excellent sexpose to instant classic gonzo status.

Opening with scenes that would have made Rocky Balboa proud—the girls jog, work out, hit the bag and end up face to face in a boxing ring—they challenge each other to "take it to another level." I’m not sure there’s another level higher than what you get in these five hardcore scenes.

Playing with each other in an incredible swimming pool, these two professed best friends shove toys into each other’s pussies and after some nasty g/g, grab Mark Ashley for a pulverizing fuck scene. While Alexis fucks Ashley, Kristina fingers her butthole and slaps her face; when Kristina has the cock inside her, Alexis chokes her out and pulls her hair. The girls love it. After Kristina squirts from Ashley’s hand job, they share his cum.

The two babes share some interesting sex toys with Asa Akira where they seem to push the Asian sex star to another level. The simmering three-way scene slowly boils over as Kristina’s asshole gets penetrated until she cums. The girls then split up, with Alexis ratcheting up the intensity with Erik Everhard, and Kristina getting fucked in the ass violently on the dirty floor of an airplane hangar by Alex Gonz after exiting a helicopter. After some A2M, Gonz re-enters her asshole as she sits on the wing of a small plane and they both cum, with Kristina squirting again. And the interesting setting where Mason places her performers adds to the eroticism.

Finally, the closing four-way with Rose, Texas, Gracie Glam and Michael Stefano goes from some excellent girl-on-girl-on-girl to some sublime fucking. In numerous positions where the girls can choke, be choked, fuck, get fucked and aid each other in the process, no holes are left unused, and Stefano in that moment looks like the luckiest guy on earth. In one extraordinary moment, Stefano shoves his large cock down Gracie’s throat while Kristina spreads her cheeks and Alexis eats her pussy, with Kristina the experienced teacher guiding her in her deep throat exploits. Then the three lovely girls share Stefano’s cum.

Kristina and Alexis exude pride as they march through their sexual orders, and with some excellent interludes of the girls just being girls—eating, driving, talking to director Mason and describing their close friendship—one gets a sense that this is more a sexual documentary. A lot of love and care went into this production and can be seen on the screen, with the high production values and in the extremely revealing BTS segment.

Like with last year’s Tori Black Is Pretty Filthy, director Mason has set the bar pretty high for other gonzo productions coming out this year.
