Is the Lucy you mention, a bigger girl with blonde hair?
Only reason I ask is that I had a 'threesome' with 2 girls in Stroud around 10 years ago, and one was definitely a Lucy and the other I'm 99% sure was calling herself Isabelle and would definitely be around 40 now.
Lucy did nothing for me, but Isabelle was very nice and I'm wondering if it's the same girl as I never made it back to see her on her own!
