What you're looking for -- young, hot, slender, White chicks -- is rare, but is what EVERYONE wants, which means the price is going to be higher than average, all other considerations being equal. XOC could be a good option for you. I've had MANY excellent experiences with them. Most of the girls there fit the bill, and nearly all of them will accept CIM for an upcharge. Private Liaisons is another possibility, though the quality is not as consistent as PL. Tryst, by contrast, is insane. Many girls there are asking $1,000.00, which I suspect they're not getting. In fact, I know for a fact that some Tryst girls advertise elsewhere and accept less than their Tryst asking price. It's buyer beware, I suppose.
As for me, I've latched on to my ATF, a 23-year-old redheaded White girl in Baltimore. She's gorgeous -- 9+ body and 8 face. She's a student at a local community college, strips part time, is a freak in bed, and a total sweetheart on top of it all! She also flies UTR to keep her family from finding out. We've got a regular, sort of sugar daddy thing going, which she prefers and is more comfortable with. My standard session with her is $400 every two weeks, on average, which includes dfk, daty, 69, cfs, cim, and showering together. Every now and then, for a $200 upcharge, she offers BBFSCIP, which is completely amazing!
I lucked into this situation when, before COVID, I responded to an ad she placed for a short time on a competing website to Tryst. She accepted the meeting and we really hit it off. After a short while, she started hosting me at her apartment in Baltimore, where we enjoy complete privacy. She's so sweet and we get along so well, it's easy to imagine that we're a genuine couple. In fact, she's marriage material, IMHO. The takeaway, I suppose, is that unicorns are out there, but difficult to find. It took me 15+ years to find mine, and I intend to ride her as long long as possible! %^) Short of catching your own Unicorn, though, I suppose the only alternative is to pay the going rate, whatever it happens to be.
