Last time we were together I was able to collect quite the sizeable sample from you, though you did break the rules and cum in my mouth. This time I'm prepared for you and your unruly ways, however. You are to be secured to the table for this session, unable to touch me unless I say, unable to touch your aching cock or your throbbing balls, which is just how I want it. This session will focus on how your sample is affected by the experience of being with a partner, of focusing on her pleasure instead of your own. Of course I'll have to use any means necessary to get the perfect sample, but I don't think you'll mind. It worked out pretty well for you last time, after all...
