I love licking a cock and have it get rock hard in my mouth. If there is pre-cum I will lick up every drop of that sweet nectar. I get excited when his cock swells up and starts throbbing as he moans and begins pumping my mouth full of his sperm. The warm cum fills my mouth and I roll it around savoring every drop of and then I swallow it all. My panties will be wet with pre-cum when I finish. They are getting wet now just thinking about it.
