Let's take a moment to consider where Rachel O (AKA Wendie, Wendie Tomass, Wendie Thomass, Summer) got her porn name. The O could easily stand for orgasm, as she both has and induces them in her movies. It probably doesn't represent any of her tight, fuckable orifices, as you'd need a tiny, superscript lower-case O for that. That said, it could easily stand for the countless times her fans and co-stars have screamed, "Oh, oh!" while she worked her magic. Whatever the case, the sometimes-brunette, sometimes-redhead cutie is an incredible fuck, and there's a ton of video evidence to prove it.
Rachel shot most of her movies in 2011, though she did a few in 2012 before disappearing from the porn scene. One of her hottest flicks was also one of her earliest: My Favorite Teenage Gang Bang 1. Rachel is the singular female star of this intense group-celebration of sex, getting hammered by the likes of Dirty Harry. This flick has almost everything. There's titty-sucking, deep-throat blowjobs, handjobs, and naturally, a fuck-ton of screwing.
She starred alongside Caroline Pierce in I Can't Believe I Fucked A Zombie, a movie that was nominated for the 2012 AVN Awards for Best Vignette Release and Clever Title Of The Year. There's a lot to love about Rachel O, so I recommend delving into her video catalog as soon as you get the chance.
