With only 1 escorting feedback in over 2 years, I suspect she has ticked her escorting box in order to atrract more punters to view her on cam (you being the prime excample).
At £250 she may have deliberately priced herself out for escorting purposes. Also, she may insist that you first view her on cam, before she deicdes if she will escort with you.
If her partner is her regular partner and he barebacks her on cam, cannot see any harm in this. I suspect at £250ph, she will not bb punters, but who knows.
Cost of Hotel will be on top!!
Personally, there are far, better escorts at much cheaper rate than her, and more importantly, KNOWN for providing consistent good services. I'd stick with them.
If it still bugs you, send her a PM and enquire about escorting and let us know what her reply is.
