This was very, very close to a neutral, but just scrapes a low positive. I'd been hoping to see Tamara but she didn't seem to be working that day, and a quick trawl around the other walk ups (see the Soho Walk Up thread for a rota) led me to see Kay.
The Woman: Kay's in her forties but in the (very dimly lit) room I thought she still looked pretty decent, at least for her age, and her natural g/h (I asked, she wasn't certain) tits were what I was there for. I was expecting someone quite chatty and flirty given previous reviews, but she was initially quite quiet, and before I decided to stay I made it clear before that I really loved her boobs and wanted to spend some time playing with them and she said that was fine, so I went for sex and oral (£40 + £2).
The punt: After getting a wet wipe and applying it to be my cock, balls and pubic hair (which seemed a bit odd as I'd only had a shower about three hours before), the condom went on before I was that hard. Still, she then gave me access to her tits, but when I went to suck her nipples she asked me not to as they were too sensitive, and playing with her nipples in general was off the table. This irritated, but otherwise I was allowed decent access, and happily smothered my face with them. After a few minutes of that she went down on me and I was impressed, her head was bloody good, a mix of sucking, tongue work and the odd bit of bobbing up and down, and I was close to coming when I stopped her and asked for sex.
£40 gets you one position, and in some walk ups you get to choose, but not here, it was missionary and that was that. Still, given how long she's been working her pussy was pretty tight, when I asked her to talk dirty she did so brilliantly, and after a couple of minutes I asked her to play with my balls and that led me to coming hard just before the maid knocked on the door.
Overall: I was a bit disappointed that Kay wasn't more flirty, and the sensitive nipples thing, but really great oral, some impressive dirty talk, and ball play leads to a low negative. I would add that due to her age she's not going to appeal to everyone, and I'm not sure if I'd go back, but I don't regret seeing her and did enjoy my time with her despite the minor issues.
