i have no personal knowledge or experience of her but would ask you - how are you communicating with her? today she says her next incall bookings are 23rd june (ok she may have prebooked all of today). And for me, i wouldn't book any escort on just a pic of her knees downwards - and certainly can't see how you could think TGTBT?
where are you seeing her ? Her place, hotel, your place etc? anyway - just be careful! For me, there is not enough in her profile to make me feel comfortable .
