The second one is Kathy and has reviews on the erotic review http://www.theeroticreview.com/reviews/show.asp?id=108604Is this one and the same ? or two different girls ?

She is fun and willing as long as you can handle strange, She is way out there. A three hole girl who hopes you spend the night for a low donation.

Haverhill has been posting on BP (Escorts & W4M) and CL, on occasion, for extended period of time.
She doesn't travel.  Only hosts in her incall location in Haverhill area.  Initial contact has always been by email.

Kathy of Fitchburg fits your description as well but she is much older than 34, more like 45-50.
