I may add to this thread in stages. I attempted to punt today without finding someone convenient to answer their phone so had thought to start a thread similar to this one.
So, here's my answer to part one. My preference is thin ladies with disproportionately big firm natural boobs. I don't ask much do I? The service doesn't have to be extensive, just friendly and some level of enthusiasm. Before my time on here I saw a girl a few times, both in Smethwick and Handsworth. She was slim(ish) with enormous firm natural boobs. Vanilla service only, but friendly etc. At one of these visits she asks if her friend can join us. I say I need to see her first. In she comes. She is thin, with a rack nearly as big as girl no1!
I had oral and sex with both of them in a few positions. My wank bank memory of the visit was with girl 2 sucking and girl 1 leaning over me with her tits in my face/mouth. Girl 2 disappeared never to be seen again so it was a one off. Such is life.
Answer to part 2 later.
