BBBJ is common but CIM is not and a tip is expected when extras are provided. True some girls don’t discuss the tip which I think is nice because it doesn’t interrupt the session with mood killer negotiation plus that way you get to decide what kind of tip the service was worth at the end but don’t expect to leave no tip. CIM is great when the girls do it, it guarantees a repeat visit from me. If the girl says “tell me before you cum” so that she can pull back before the explosion I respect that but it makes me more judgemental about the quality of the blowjob when I’m deciding whether to repeat and I leave a better tip for CIM. If Kourtney gave a bj good enough for a repeat than she must be good at her job.
