I don't do VIP on most visits so I don't necessarily have an M.O.
When I SC it's often on dayshift and/or dives where I just wear my athletic commando shorts which are roomy and have a very wide leg - I can just lift/move-up the leg of the shorts and take out the artillery - if not wearing my athletic shorts then it's usually my lounge-pants which are roomy and have an elastic waistband and I can take out the weapon over the elastic waistband.
If it's a club I am comfortable/familiar with, and a dancer I am familiar with, I may take off everything - my go-to small black club not many people do VIP so there isn't a wait for the rooms thus I will usually not be bothered by staff and I feel comfortable taking it all off and if it's a dancer I know - so for me it kinda has to do w/ having a certain comfort-level/familiarity for me to take it all off.
