I gave my boyfriend major blue balls the last time I sucked his cock!! I played all sweet and innocent, making it seem like I was about to make up for it in a BIG way. I teased and licked his cock until he was ready to explode. I kept telling him, don't worry, I promise I'll let you cum this time. Then right as he is about to explode, I get up and apologize, "Sorry, I guess I'm just a little cock tease after all!!"
