If you watch the most recent scene [The one where she's the Robot Assistant with the Silver Painted Corn Rows] there's a couple of points where they both mention fucking her ass... he fingers it a couple of times... and at one point when he's going for her vag... he misses and brushes up against her butthole... and if you listen closely... you can hear her say "It's not time for that yet".
YET! being the keyword.
She's got it planned. She's just playing the long game that most smart, in-demand, porn-starlets do.
The long game consists of: Softcore Solo, Lesbian, Normal Vaginal Straight Sex, Male+Female+Female, Vanilla Male+Male+Female [a.k.a. No Anal... no Double Vag]
The final steps of the Long Game are Anal, Interracial, DP, DP + GangBang, DP + Interracial Gangbang, and then on the final end of the spectrum is a GGG/John Thompson or Legalporno Piss/Cum/Gag/Gape/Bukake Gangbang. The game is played roughly... in the order listed. This insures that when these milestones are met... they're maximizing their profits... and staying relevant.
Some starlets are just filthy nympos and jump right into that Legalporno DP+Gangbang stuff [or they are told "hey... there's a payscale... down here is Solo and Lesbian... and Up here is a DP Gangbang+++... how much money do you want to make today? And they're just looking to get paid as much as possible... as quickly as possible... but if they hold-out... and they're as in-demand as Nicolette knew she'd be... they know they can hold-out and get way more for it later on].
i wonder if she is ever going to do any anal scenes
