Having seen both- Rhianna has a nicer face in my opinion. Mixed girls are really quite attractive. Armani's face is kind of average girl-next-door.
Both are young, spinner types but Rhianna is kind of lackluster. Nice girl, attractive face and body, but service is mechanical. I'm average in pretty much all departments but my hygiene and manners towards the ladies are impeccable- so I don't think there should have been any cause for her to dislike me in particular. I guess she's probably a YMMV sort of gal? Didn't opt for BBBJ, wasn't offered, prefer to get CBJ anyways just cause I'm paranoid like that. Open-minded so no DFK or Daty (oh, the irony of misleading terms!).
Armani was quite a bit more talkative and well-spoken. I'd peg her at around 22-23 ish, but she's got a sort of maturity about her that makes her fun to talk to. Energetic and quite enthusiastic, nice to cuddle up with after some doggy. Small boobs, nice tight bum. She's tiny but has muscles, in good shape although there are some stretch marks around her belly (not really noticeable with the dim lighting but you can see them when you're close to her). GFE, so kissing and Daty were included. I think my one beef would probably be her hair- there's way too much of it (some extensions, I think? Looks kinda damaged) and it kind of gets in the way. I actually had to pull a few hairs out of my mouth at one point. I wonder if girls with big hair cough up hairballs every now and again lol?
One thing that I think some of the guys would appreciate is that Armani does massage pretty well, particularly head and face. It came as a nice surprise after a rather quick finish with quite a bit of time on the clock. If you're spending 300+, you want to get your money's worth- I would suggest going with Armani.
