Some sex workers put a limit on how many times someone can come in a 30 minutes but I never did.To me they pay for my time not for how many times they pop.Very few can come more than once in 30 minutes but if they do then good for them.Makes no odds to me as long as we are done and dusted and he is out 30 minutes later.My service was the same regardless of the length of time they booked except for more unusual requests like sploshing or if they wanted to cram a lot of things in to the booking but that is common sense.A shared shower,oral both ways,face-sitting and multiple pops is just is not achievable in 30 mins realistically,but a straight forward gfe is fine even with 2 pops.
