Well if you’re the type of guy that does 2 shots in a session, one of them being cim, and you also go for rim, going with dongguan can save you 20 to 40 compared to going with cim, rim and msog as extras. Thing is that what dongguan is varies from agency to agency. I’ve had the experience where it doesn’t seem like the girls knows what the expectation is when I ask for it, or say they only give you the cim but not the rim, so I tend to lean towards just asking for what I want as extras. That way they are clear on what I’m looking for. What you won’t find here is real dongguan, which is too bad because it’s a pretty great experience.
