I see Khloe Kay, the superstar has an in Vegas. Anyone seen her yet? She's always been my dream date. Her ads a little pricey at $1500, but I'm debating taking the plunge for a shot at seeing her before she disappears. I don't ever recall her being available in the past.

I posted about her ad in another thread. No reviews or anything on the web that’s helpful. Maybe ask if she will FT verify? If it is her, definitely worth paying premium for a shot. She’s stunning.

I was texting her last week. No Incall, unless shes seen you before, so gotta get a room in Vegas.  
Seems legit from texting back and forth, but hoping the performance would match.

Treat yourself. She looks fun. $1500 for your dream date? A bargain! Be sure to review her if you go!

... got me wondering 1) what is a dream date session (excluding the t-girl being highly desirable), 2) how often does a 'hobbyist' with t-girls indulge and at what typical price?

I think for a “dream date”, meaning a girl that is everything you could ask for, $1500 is worth it. Especially if the clock is ticking and you might not get the chance again.  
As for the other questions, might be a good topic on its own… I think you’ll see a huge range of answers.

I wouldn't call 1500 a bargain, that's for sure.  
As far as dream date, I live Khloes looks, body and cock. I find her to be one of those most attractive TS pornstars out there. I would hope her performance matches.

She's got a great ass that seems pretty natural and she recently got a great boob job. She's definitely someone I'd love to fool around with.

A few years ago, before implants KK was super hot.
