The box with the vibrator sat on the table like an elephant in the room. I thought hard trying to think of something cute to say that would lighten th... situation. I wanted to bring the conversation around to the vibrator without being too direct. My mind was racing more than usual, if that is possible. "So, how long do the batteries last in those things?" I can't believe those words actually came out of my mouth. "Why do you want to know?" She laughed as she asked. "Oh, just curious." Best. I'll get you for that you dirty old man," she said as she walked quickly toward the beach-side door. Once she was through the doors, Christina broke out into a full-on sprint. When she reached the sand, she turned back toward me and removed her dress.Standing there in all ner naked beauty, she issued, "If you want any more of this pussy, you'll have to catch me." Christina took off down the beach as she tossed her dress in the air behind her. I took off after her and only slowed to grab her. I put a lone finger over my pursed lips and shushed him. As I did, I pulled my skirt higher and rubbed my hand over my pubic region. “No, no, no,” he replied. I stood up and unzipped the zipper of my skirt, allowing it to fall the ground. “No, no, no,” he again replied, as I bent over and retrieved it, placing my skirt in my cart. All I had on at this point was a very wet pair of low cut, black see-through panties and a tight-fitting top. I silently stripped off my top, baring my perky 38D. I will confess that I was/am not in the best physical shape. But I am far from fat since I loved/love swimming. I have an 6 inch dick that loves sex, its always hungry to empty its juices into a hole.I was rock hard. But I pulled out the ballgag despite her protests and ordered her to suck it. As she refused I pulled out from my jacket the slave necklace. It was a simple leather collar with the words "I am a slave to my master" engravid on it. I lett her look at it and the put it around her.
