I'm not sure about popping more than once, being a 1 pop guy myself. I'm sure it wouldn't be a problem to Nat though. She has her routine, with me I'm face down for the first 30 mins. Where she does her thing, so no popping there, then turn over for a wonderful experience, where you are likely to pop prematurely. (I don't). Nat does a fantastic service. I'm sure you will enjoy. She's also very eccentric and interesting, and a good laugh. But most importantly gives me the most intense orgasms ever. I like her service a lot, and will keep returning.
Hope you enjoy.
