I had been going with Vanessa for almost a year and knew she was into "kinky" and liked to try new sexual adventures. When she was in just the right mood, she liked to be bound and mildly tortured. Not any real pain, but just enough discomfort to remind her that she had given me complete control of her body. She said she hated it when I would bring her tightly bound (and sometimes gagged) body to the edge of orgasm and then stop but I knew she didn't want me to stop doing it as a part of our "play". We had set up a Master/slave part of our sex life and she loved being dominated from time to time and "forced" to do things the "real" Vanessa would never do. I introduced her to anal sex that way and it soon became a part of our "normal" sex life as well.

Vanessa was a stunning brunette of 28 with long hair (to her waist) and brilliant green eyes that flashed fire if I went beyond what she was prepared for. I always took that look as a signal to back off and build her up a little more before going ahead with whatever it was I wanted her to do. Her body can only be described as "perfect". She tended to think of her shape as "too hippy", but it seemed just right to me. At five feet, one, and 105 pounds,she was certainly petite and her 3422-35 figure made her look like a miniature centerfold. In fact, she often got modeling proposals from local agencies and photographers and took a few jobs modeling sports clothes and swimsuits. I always got a big kick out of seeing her in an ad or catalog when I didn't expect it. Her breasts were full without being too big for her small body and her vagina was as tight as it could be and still allow entry.

Well, here's story for your pleasure....................

She was lying on her back on the soft carpet of her livingroom floor and I was kneeling by her head as she gave me some of her very special brand of fellatio. Her mouth was quite small and when she sucked me her lips drew out to thin lines around my cock. She used her tongue constantly and usually tried to get as much of my member into the small cavity as possible but with only limited success (I am rather well endowed). When her Collie "Red" walked between her legs and began to lick at her spread pussy, I expected her to stop and shoo him away but to my great surprise she kept sucking and handling my cock and balls almost as though nothing unusual was happening. I could tell, however, that the dog was having an effect on Vanessa and her hips began to rotate and thrust in response to the rough lapping of his tongue. For some reason, the sight of Vanessa being aroused by her dog triggered my pent up orgasm and I began to come hard into her sucking mouth. She gulped and swallowed and milked me with her hands until I was completely spent and, with my softening cock still in her sucking mouth, she reached her climax and moaned loudly as she came.

Later, she said Red had never done anything like that before but it sure felt wonderful. I pointed out that Red had seemed to enjoy it too but certainly not to the extent that Vanessa and I had. Then looked at me questioningly and said, "What do you mean?" I said that Red hadn't come and that really didn't seem very fair. She was very quiet for a few minutes and I could tell she was mulling over what I had said. Suddenly, she assumed the submissive posture we often used when she wanted to be controlled; on her knees with her head bowed and her hands clasped behind her back. This was her signal to me that this was something she could only do at my direction. I knew she was curious but bestiality was well outside the realm of the "real" Vanessa. "slave" Vanessa, however, would refuse nothing required by her Master.

I called Red to stand before her and instructed her to stroke the dogs genitals and try to arouse him. I petted Red as she did as I instructed and at first, he didn't seem to get the idea at all. He stood and enjoyed my stroking but seemed unaware of the different kind of stroking he was getting from his mistress. Vanessa looked at me and said nothing was happening so I suggested that, perhaps, she wasn't using the right kind of stimulation. She pretended not to know what I meant so I said that her hands were dry and might not provide the kind of touch that would get Red's attention. She looked into my eyes and said, "Do you want me to use my mouth?" I smiled at her and said, "Those lips of yours can stiffen a noodle, my dear. I think you should give it a try."

Slowly,she lay down and slid her head beneath Red's rear quarters. I lay down on the other side of the dog to observe and she slid back the hairy outer sheath with her hand to reveal the red tip of his penis. Tentatively she raised her head and allowed her soft lips to enclose the red flesh as she flicked her tongue against it lightly. When she lowered her head again, it was clearly extended a little further and I said, "Now, you seem to be getting somewhere. I think you should continue. This is so depraved," she said with a little giggle, and thrust out her tongue to further tease the animal into erection. When his cock was out about three inches, she gently drew it between her lips and began a light sucking. Red was starting to squirm around and hump against her lips as she sucked and I had her get up and kneel on the carpet. I directed Red to a position behind her and he licked her wet pussy wildly. Then, I raised his front paws and placed them on Vanessa's back. He got the idea almost immediately and started thrusting between her legs. Her vagina was clearly not where he expected it to be and he was nudging against the rosebud of her anus so I reached between them and "lowered his sights" a little so that he slid between her wet lips and entered her pussy.

Vanessa said she could hardly feel his tiny cock and he kept slipping out, so I took some of the fluid dripping from the lower part of her pussy and applied it liberally to her anus, sliding my finger in to the first knuckle. She gasped and turned to look in my eyes, realizing what I had in mind. "slave" Vanessa could not, of course, refuse, but the real Vanessa might take control. She didn't. I repositioned Red for entry into her well lubricated ass and he thrust forward and entered her immediately. Vanessa lowered her beautiful head to the floor and groaned, "Oh God! This feels so weird!" I had her describe for me how it felt to have the dog's thin prick sliding in and out of her ass and she made the description as dirty as possible using words and images that only the "slave" Vanessa would consider so as to heighten her feeling of submission.

When I thought Red was close to his climax, I said, "Now suck him off." Without hesitation, Vanessa pulled free of the small cock and rolled onto her back as I guided the, still thrusting, Red up her body until his stiff red rod (now, almost 4 inches long) reached her lips. She put her arms around his hips and drew him into her mouth, allowing him to fuck her tightly pursed lips. After a few seconds, the dog let out a small "yelp" and I was sure he was releasing his sperm into Vanessa's mouth. She held him tightly between her lips until he was finished and when she pulled her head away, Red scampered off and she opened her mouth to show me the small pool of white liquid on her tongue.

Before she swallowed, I noted that it was much thinner than human sperm and she told me that it had a more bitter taste than mine but was really not unpleasant.

While the "real" Vanessa pretended that the incident never happened, the "slave" Vanessa told me how kinky she felt knowing that she had done something none of her friends would even consider. She talked about her sex with the dog often which convinced me that several repeat performances were in order. Finally, I told her we should videotape her with Red. She seemed very reluctant and I encouraged her to talk about her feelings. At last, she admitted that she would like to watch herself with Red but was terrified that anyone else might someday see the tape. I told her that she would keep the only copy in her possession and could erase it any time she wanted and she got very excited by the idea. We made the tape a few days later and she went out of her way to give the performance of her life and make sure the camera caught everything. She even pulled Red from her lips as he came and let the cum fall on her lips and cheek.

Later, she gave me that tape (and several others) as a "gift of trust" with the understanding that no one would ever see it but me. I have kept that trust.
