And?
Riley waited to do IR so she could get more money for it. Billy Watson (the guy who shoots for Blacks On Blondes) confirmed this on his blog. It's the same as Amy Ried holding out for megabucks to finally do anal. It's called being clever...it's the polar opposite to the Sasha Grey approach, wherein you do everything straight out the gate and don't leave yourself any unexplored levels of work to fall back on.
Word is Riley is retired now (whatever that means in the topsy turvy world of porn), but if she were to unretire tomorrow, she's still got a laundry list of unexplored levels up her sleeve. She's got her first anal, her first DP, and so on, all of which she can very likely parlay into a hefty fee for her 'first ever' shoot.
Sadly, fucktards who populate forums like ADT and the Mr. Marcus forum still can't see that some girls are just playing the game intelligently, and because they haven't done an IR scene they must be dodgers, racists, or fully paid up members of the KKK. The idea is to do as little as possible, parcel your levels out and get an increased fee for your 'first time' shoot. Remember, Jenna Jameson has yet to do anal, DP, IR...and why should she if she can get by just fine doing what she does already? Is Sunny Leone a misandrist because she has yet to take cock on camera? No...but any girl who hasn't done IR yet is a Neo Nazi.
Incidentally, Riley's first IR scene was in Take It Black 5. Despite the fact that both Van Styles and Billy Watson post on the Mr. Marcus forum, both the scene from TIB#5 and her BOB scene were posted on the site...the BOB one within 24 hours of it appearing. She also has IR scenes for Gloryhole and Ruth Blackwell in the can.
Remember: Less money for producers=Less money to tempt talent to up their levels=Less IR holdouts going over to the dark side. But don't try and tell them that...perhaps some producers need to alert Mr.Marcus to the economic realities of the current situation?
