Does anyone know of any wam Sessions around the London area? I have done Splosh a girl in the past, which was great, but I don't think they are operating at the current time. Any suggestions would be great.

You could try Araneae who is based close to London she's great fun! I've sessioned with her a few times and always had a good messy time combining several kinks.
