I've seen Marianne a few times now. Consistency good service and not a clock watcher.
Differs a bit from the others as she keeps you guessing a bit longer as she carries on massaging you after you have turned over and only asks about extras with about 15-20 mins to go, but last two times has over-run by about 15 mins anyway so not a problem in the end.
B2B, 69, cim and swallow (if you do cim!), for £50 .....not bad!
Might be up for fs as well I think once she gets to know you more
