Last year I was walking around soho area and a punter came by me and asked if I was looking for a WG. I said yes and he took me to this area of soho which was in a alley way. Punter requested a tip and I gave him £5 which at that time I knew nothing about UKP and Soho walk ups

I went upstairs and knocked at the door. Her maid came out and said she was busy. She then told me there was one more WG in upper flat. I went to the upper flat and before I could knock at the door, A busty blonde lady came out and said if I was looking for sex. I said yes and she told me to come in. She pointed at the wall with paper stuck on it. It was her rate. She offered £65 for OW and sex for 30 min. She had this African maid who was I believe in her late 20's, rude and kept on staring with angry expression. I agreed with 30 min and then she led me inside the room. I gave her £ 65 and £5 for the maid. She went out to put the money. As I was removing my clothes, my phone rang and the maid yelled from outside "TURN YOUR PHONE OFF"
The blonde came back inside the room and stripped and started stroking my cock. She then puts on a condom and started giving BJ. As she was giving BJ I started playing with her tits. She yelled "NOT THE NIPPLES"

. I then got on top of her and started fucking her in missionary. It wasn't even for 5 min and she asked to change the position. I obliged and fucked her doggy.
After a while she got on top of me and started fucking in reverse cow girl. I was feeling uncomfortable in that position in that position as she was quite large for a skinny man like me. I tried to move her, so i can fuck her in doggy again. As I tried to move her, she angrily said "CONDOM IS NOT GOING TO COME OUT " as if my penis was very small. I said to give me BJ and then she gave for a minute maybe and then started giving HJ. I grabbed her tits avoiding the nipples while she was giving HJ. I popped in condom after few min. She pulled the condom off from my cock , I put on my clothes and went out without looking at any of them.
Long story short, If anybody know the name and location of this WG by the description that I have provided , let me know the location as I don't want another encounter with this person by accident in future.
