I have seen both Paris and Kelly. I first saw Paris in 2020 (then going by the name Coco) and was simply blown away by her! When I booked her again (or thought I had) some months later, I arrived to be greeted by Kelly - I went ahead with the punt (which was pretty good) but she just doesn't do it for me physically and certainly not the way adorable, little pocket rocket Paris does!!
I have since seen Paris on numerous occasions - she often messages me to let me know she is in town - and in fact she is practically the only cis sp I bother with these days. Our default language together is French so in the past I would phone up to make a booking enquiry and speak in French - Kelly doesn't speak it, so straight away I would know who I was actually dealing with......in truth she always used to be pretty up front when I then asked if Paris was available....as far as I can tell, sometimes it is just one of them on their own (but both profiles and numbers are used by whoever is working), whilst at other times they are both visiting together - in which case, unless very specific when booking, it will end up just being pot luck as to who you actually get to see! Paris is clearly by far the most popular of the two (and with very good reason), so I have never quite understood how she benefits from this set up unless of course she also gets a cut of the business which it brings in for Kelly.
