Not asking for recommendations here, just a curiosity I always had.
When looking at ads on AW etc, almost all indi's that do CIM also offer swallowing, but almost never see it listed on parlours (even as paid extras). When sandys was open in Mcr, they had whole lists of extras (at the discression of lady of course) including OWO, CIM, WS, etc. but even they never listed swallowing? I never asked so maybe some did offer it without it been listed??? or is CIM + swallow in a parlour a "no no" for some reason?
