Julia was happy to see you when you found her. "Hey! I've been hoping to find you here! I have to ask you, what are you thinking???"
Huh?
"You hadn't cum in over 3 weeks, then I give you the medicine that will allow you to have an earth-shattering orgasm, and you drive away to give it away? What? And now, its almost 2 weeks later and you still haven't cum! And to top it all off, now you're locked in a chastity device? Wow, I don't get you."
She had a point. You didn't quite understand yourself sometimes either. But you understood how hard your cock was straining when Julia stood up and started peeling off her bikini.
