The rare times I have done incalls in hotels I take bog standard mouthwash and some moisturising shower gel. If they want deodorant they can bring it with them.
I wouldn't give them anything expensive to use. And I really wouldn't use anything like lush, you don't know their personal lives and trying to explain why they stink of lush would be very, very awkward. Plus it could lose you a potential regular. Discretion is a two-way thing in this business.

Seriously though the amount of times married clients have opted for smelly shower gel over the unscented stuff in my experience...in fact some of the only very anxious ones on this front are guys who’ve been caught out before (their own admission) and have wives that ‘sniff them out’.
I sometimes think to hide the more expensive toiletries but that’s more to save them for me, though I would never actively jeapordize a clients discretion I don’t see that their personal life is my responsibility either. I did manage to notice and pull some white blonde curly hair from a guys shirt once as he was about to leave but god knows how many tines shit like that escapes his and my notice. I also don’t really know how lingering wash scents really are, I’m always cussing how little toiletry smells stick around but maybe I’ve not got a sensitive nose.

Yeah probably that’s true. I did work out that an ex cheated on me in a brothel because he came home smelling of baby oil. That shit is pungent, but the I knew that brothels use it a lot. I stayed with him a while after that but I became hyper aware of these things which I really hadn’t been before. Which is why some dudes are very lax, if they’re wife doesn’t suspect them already she’s less likely to notice. Still as long as low scented shower gel or soap is on offer, it’s up to them to decide.
