This often happens when I get a sensual massage. Things got heated near the end, he is stroking me, I may be sucking or fingering or stroking him. He is moaning, I am excited. Here is the thing, I am never sure if he is “acting” or genuinely turned on. Usually how it ends is that I finish and he helps me clean up. He never finishes. (Which I really want him to). If this was a hook up, I would want to be a considerate lover and see what I can do for him to finish. But this kind of arrangement I am not sure what to do. Any one have suggestion?
