I have a reputation to maintain at the clinic, I always send them the best trained sperm donors."My balls did ache after Rachel had finished with them...that evening. She encircled my sacs with her finger and thumb and gently coaxed them down and away from mybody, stretching the soft skin that contained my two hard testes so that they hung low.
