My boyfriend, Jack, is a complete extrovert. Give him a room full of people and it's like a light bulb being switched on. A story for every occasion. More jokes than a stand up comedian. The life and soul of every party. You either love him or hate him. Thankfully, I'm in the former. Well, most of the time anyway.

Don't ask me why I did this, because I haven't got an answer. It was done on a whim. A spare of the moment, without thinking, thing. Let me explain.

We were out for drink with a group of friends. Jack had already told one story and was about to embark on another, when I leaned over and whispered in his ear that I wasn't wearing any knickers. I did it, I suppose, for a bit of fun, thinking that Jack would see the funny side. What I didn't expect was his reaction. He started to redden from the neck up, looking decidedly uncomfortable. He was suddenly lost for words, totally flummoxed. People around us must have noticed because they asked him was he feeling ok. He squirmed about in his seat. Then, finally, after a while he wanted to go home. He had suddenly become a little boy lost and, god forgive me, I made him suffer. I was no longer the submissive girlfriend and I was loving it. I said the night was still young and started to flirt a little. When I crossed and re-crossed my legs I swear to god that I could almost see steam coming out of Jack's ears. And the funny part, the irony, was that my underwear was, all the time, still precisely in place. Of course I couldn't be so cruel for it to stay that way. So, before we left, I made sure my knickers were in my handbag.

I barely had time to close the door behind us. Jack had me right there, up against the wall, in the hallway. There was no preamble, no foreplay, just sheer desperation. Jack's jeans where around his ankles, my dress around my waist and Jack was inside me. Such was the intensity that he slid me up the wall, lifting me off the floor. This wasn't making love, or having sex, this was two animals, fucking. I got my hands under his shirt and clawed his back and we both moaned. Something of this intensity couldn't last. We came together, Jack pumping inside of me, my pelvic muscles holding on to him for dear life. And it went on and on my whole body was one long orgasm.

Now, when we go out, Jack insists on a knicker inspection. So, I have to pull my dress up to let him see that I've got them on. The first time this happened Jack was back to his usual egoistic self. Of course when I whispered that knickers were quite easy to remove he lost some of his bravado. Now he watches me like a hawk. He starts to squirm when I go to the loo. Am I still wearing them when I come back?

Well! that's for me to know and for him to find out,a8 isn't it?
