I prefer two hours as the girl can demonstrate her various skills without rushing. I used to be the regular of a Japanese-Korean girl in Sheffield (Japanese national with a Japanese father and Korean mother) six years ago and would often have three hour sessions with a fantastic massage in-between the rimming, ball sucking, oral without and protected shagging, but she's the only girl I've bothered to spend that much time with, and only because of the exceptional service she offered.
I started punting in my mid-20s, visiting parlours in Greater Manchester, so 45 minutes to an hour was what I was used to before visiting independents, then two hours minimum is what I decided upon.
This has got me feeling nostalgic now. Back in 2006-08 I used to regularly see a pint-sized black girl in Swinton, at a place called the Toucan Club (think it's shut down now). Her parlour name was Casey. She had a toned, athletic body but tits like a Spaniel's ears. Christ, she gave fantastic head right down to the balls and would bounce on you for ages. Does anyone else here remember the place and girl? I miss her, she's a legend.
