In her mouth

“Fuck... I'm gonna cum!” You warn her. If Katie cares, she doesn't show it, and continues to slide your manhood in and out of her mouth, her lips tightly sealed around your shaft.

You cum with a grunt that makes your whole body shudder. Semen pouring into her mouth in great spurts of ecstatic release. You never see it, however. Katie swallows it back almost as fast as it comes, leaving plenty of room for more. In fact, she refuses to take her mouth off your cock until she's sucked and squeezed every possible drop from you.

It's your turn to be left in a daze, and by the time you're able to begin pulling your pants up, Katie is already stepping back into her slinky black dress. You're just fastening your belt when she opens the stall door and you look out. There's a middle aged woman standing inside the bathroom, having apparently just walked in, her face one of absolute shock.

“I'm getting the manager.” She barks, racing out of the bathroom before you can say anything. You and Katie look at each other sheepishly.

“I don't think we're eating here tonight.” She giggles.

“I don't think we're eating here... ever.” You laugh. Dashing out of the bathroom, you make a beeline for your table, throwing some cash on it as you go by to cover the wine and appetizer you never got to enjoy, and then heading straight out of the restaurant before the manager can find you.
