I saw jennifer_pussy two or three months ago, before I started using this site, and my experience was very similar to Lazzarus78s, although she didn't try and charge me £120! She kept me waiting outside the building a good ten minutes or so and then rushed me out at least five minutes early, but in between she gave excellent OWO was very energetic and enthusiastic, getting me to come twice in the 40-45 minutes we actually had. She was also sniffing a little bit and claimed she had a slight cold. In retrospect, of course, she had been taking cocaine (which is probably why she was late), and her hyperactive sexual performance was almost certainly the result of that.
Funnily enough, I might have thought her reasonable value had she charged £100 for 45 minutes in the first place - it is, after all, the going rate at HoD, but as it was I found myself leaving with mixed feelings, and that, together with the cocaine use, means I won't be returning, which I might have done otherwise.
