As I discussed in a previous letter, I had accepted the role of being the door prize at the swinger parties held by my step-son John and his wife Christine. I would arrive before the guests did so, and cover myself in whatever little costume they had prepared for me. I was a kitten, a bunny and a puppy on various occasions. And of course was required to wear the uniforms of a French Maid, a school girl, a nurse and, my favorite, a nun. As the guests arrived I would see to their drinks and satisfying their needs. The various couples would have me dance and strip before them. Wives would feed their husband's cocks into my mouth, and have me eat their horny little snatches as their husbands fucked me from behind. Men would take turns having anal sex with me as their friends watched, or had me suck their cocks. I enjoyed these parties immensely, but I noticed that Christine seemed to have largely lost interest in them. Yes, she would let the men their fuck her. Yes she stroked and sucked their cocks. But her expression was bored, and her gaze was distant.
When I asked her after one party if she was no longer interested in the swinger lifestyle, she replied in an accusational tone that of course she was bored with it, as I had introduced her to fucking a big cock by tricking her into letting my lover Tom fuck her. This encounter is also described in a previous letter I have written. Tom, myself and Christine do get together rather regularly for a threesome. And it is amazing to see how she attacks his big cock with the eagerness of a hungry slutty school girl. When we are together, I barely get to enjoy Tom's cock at all, as Christine is immediately upon it with her lips, eagerly gulping his length into her throat. Soon she is on her back begging him to fuck her soaked cunt with his 10 inch prick. I kneel alongside Tom and holding his dick guide my lover's big cock into her slutty snatch. She moans like a $10 whore as his full length penetrates her, and he loves to grope at her bouncing firm tits and squeeze my heavy breasts while he rams himself in and out of her. He had to force fuck her a few times in the ass to make her the obedient slut that she has become. But now she accepts his massive dick in her butt without complaint. Tom enjoys having us perform 69 in each other before him, and then to alternate fucking my ass and Christine's ass. I will tell you this. It takes much practise and patients to be able to take a thick 10 inch cock into your ass. Christine is learning, while I of course am well trained and my ass accepts Tom's cock now as freely as does my cunt.
But back to my story, Christine's indifference did not seem to be explained away by these fucking sessions of ours and I suspected that there was more to this story than she was willing to disclose. So when alone with John I asked how their love life was outside of their occasional swinger parties. He explained that Christine had all but lost interest in sex. He said that she would only let him fuck her infrequently, and even then seemed distracted and distant. He said that she often stayed late at her law office and wondered if she had found another lover. I had come to grow very fond of John, he was a fine man with a great heart. I felt bad, knowing that I had tempted his wife to fuck outside their marriage and their agreed upon swinger group. And so I offered to spy on her if he liked and he accepted my offer.
Visiting Christine's law firm the next day under the pretense of going out for lunch, I was able to see the office in which she worked. Introducing myself as her step mother, the secretary showed me to her office. This gave me an opportunity to see the people who worked there. Many of her co-workers were old men and women, but some few were young and good looking. In particular I noted two tall very handsome young black men who were clearly twins. They eyed my bosom and I noticed them glancing at my ass after I walked past. The secretary explained that they were the Kingston twins, young interns who she claimed with a smile were the life of every company party. Christine's office was large and plush, with a large desk and soft chairs and sofa. It was on the ground floor of the building and had a large window at the back with heavy closed curtains.
Before she arrived I decided to adjust the curtains, carefully, at the edge, leaving an opening through which an observer outside the building could discretely peer in and see most of the room. I also slightly opened one window, admitting an outside viewer to overhear conversations within. When she arrived she said "What the fuck are you doing here you stupid whore?" Always a joy to meet. I explained that I had come over thinking she might like to go out for lunch. "Listen you idiot fuck tramp," she explained "You are a fuck toy for my husband and our friends and never ever anything more, a simple slut. Not get the fuck out of my office and never let me see you outside of our arranged meetings again!" Well, I guess I was told. I went and sat in my car and waited. I watched as everyone left the building. But everyone did not leave. I specifically noted that Christine had not left. Nor the Kingston boys. Exiting my car, I quietly went around back and took a look into her office through the opening I had left.
From my viewing position, I could see just the edge of Christine seated at her desk. She was typing away at her computer. The door to her office was shut. I waited for some time thinking nothing was suspicious. But then a knock came at the door. I was able to hear her say "Come in." quite clearly.
Then I watched as the two tall well build black twins entered her office. "The office is all ours again Christine, everyone else has gone home." One said.
Finishing her typing without responding, Christine then stood, straightened her professional but body hugging dress down over her curvaceous body, and strode over to the men. Her blonde hair flowed behind her as she walked, and her calves tightened from her high heels. Standing before the men she announced "Well then gentlemen, let us begin, shall we."
With this one of the men seized her by the arm and twisting it behind her back placed both hands together and pinned them. The other man called her a slut and slapped her across the face. Sliding his hands down her body, over her breasts and proceeding down to her thighs, he grabbed the material of her skin tight dress and pulled in up over her hips. She had no panties on and her bare ass and shaven pussy were revealed to their view. Placing his hand over her cunt and appearing to finger her, the man in front uttered "Is the white slave's cunt and ass needing of a good hard fucking today?"
