It's the best feeling when your sub falls in love with you. You are able to take take take and their regret for sending seems to disappear almost altogether. I've had 5 subs fall in love with me, one of which wasn't a finsub until I conditioned him to become one. This is why I like long-term servitude. The thrill of a quick drain is fine and hits the spot, but the regulars that keep giving make every day delicious.
