There you are, how are those poor balls of yours doing? Full? Aching? Blue? mmmm, good, just the way I like them. And you're cock? Hard? Throbbing? Frustrated? A little sore? Excellent. Well, you've done well so far baby, not much further to go now *giggles* at least not for today.
Massage those aching balls with your dominant hand while you stroke slowly with your non-dominant one. Do that for one minute.
