I've planned a special birthday evening for you. The evening starts with dinner at a quiet, elegant restaurant out of town. A number of well-dressed couples and groups wait in the lobby to be seated. You're wearing a sheer black dress, I'm in a tux. While it's not obvious when the light is dim, in the light of the lobby, the silver rings in your nipples and the chain connecting them are visible, as is your shaved pussy. Around your neck you wear a black leather collar with a single stainless steel ring in the front.
In the lobby, people stare--women in disgust and jealousy, men with looks of longing and arousal. While we're waiting to be seated, I slip my hand under the back of your dress, running it between your cheeks, gently probing with one finger the sensitive flesh between your buttock and thigh, between your pussy and asshole. As I slide a finger into your pussy and then drag the wet finger up over your sensitive anus, you tense and give a low moan of pleasure. I withdraw the hand. Catching your eye, I slide the wet finger into my mouth.
During our dinner, the waiter can not be helpful enough. Frequently you reach down between your legs to pleasure yourself. When you see that he has noticed this, you look him in the eyes as you pull your hand from between your legs and slide two slippery fingers into your mouth. He drops a tray of food at your brazen display. While he and a waitress serving a nearby table are down on their hands and knees picking up the food and dishes, you spread your legs and move your chair back so the faint light can catch your smooth, wet, swollen pussy. The waitress freezes when she notices your bare pussy. You slide a finger between your wet labia and use the moistened finger on your clit. When looks up, you lick your lips and smile at her.
