Jim had told me that he was going to take me to a party and that he expected me to wear my sluttiest clothes. I was excited because I thought he planed to take me to an orgy with his friends. I had chosen a fishnet dress and instead of a bra, I put a pair of crossed red tapes on my nipples. On my way driving to the address, the catcalls and whistles from other drivers ensured me that I had met Jim's demand.
I had met Jim about a month ago in bar. He was a bulky and brooding kind of guy, and judging by his clothes and watch, it was easy to guess that he was rich. I confess that the money was an important motive for my flirting with him, but after our first fuck, I realized that I had the whole package.
He fucked me roughly, usually in the ass, and was not shy to spank me or pull my hair during the sex. He never cared if I had an orgasm and let me go whenever his business was over. I enjoyed that, because I liked my guys to treat me like the whore that I was, and despised the sensitive type who made me want to vomit by treating me like a princess. Even the gifts he bought me were for his own benefit, and included slutty lingerie, sex toys, and perfumes.
He was the perfect guy, except for an unimportant detail; he already had a girlfriend.
His girlfriend's name was Katherine and I had seen her a couple of times when she walked in on us while we were having sex. As far as I was concerned, she was a weirdo and I did not know what Jim saw in her. She was a short, flat-chested girl who wore glasses and always had a book or booklet in her hands. According to Jim, she was a PhD student.
I did not feel threatened by her because I knew she had nothing to compete with my huge boobs and perfect ass. The weird thing was that she did not seem to worry about Jim fucking me. She even apologized after the first time that she saw Jim ass-fucking me in their bedroom, and hurried out to let us finish our business.
After a while, I gave up trying to understand her.
I found the building and had an exciting walk from my car to the flat. The door was opened by girl, who seemed to be surprised by my sight. She had short hair and was wearing a black T-shirt and worn-out jeans. She checked my whole body and grinned. When I introduced myself and told her that I was invited by Jim, she moved a little and gave me narrow passage to get in. She made sure that our bodies touched. Definitely a dyke.
The flat was spacious, but it had a modest decoration. There were many bookcases around the living room, and a sofa and some armchairs were in the middle. There was also a huge painting, which showed the nude muscled body of the dyke who opened the door. Jim was already there, and I was disappointed to see that he had brought his "real girlfriend" too. I was also mortified to see that everybody was dressed casually and I was the only one with the slutty outfit.
There was another girl, a goddess, in the living room, who was so beautiful that I forgot about my humiliating situation. Her red dress did not much to cover her slim figure and long beautiful legs. Her pale skin made a sharp contrast with her dark red hair, and her big hazel eyes shined under her intelligent eyebrows. It took me some moments to realize that I was gawking at her.
Jim introduced the two girls. The dyke was called Jessica, and the goddess was Jim's sister and her name was Chelsea. He said that her sister was a painter and she beautiful work on the wall was created by her. He then introduced me.
"... and this is Mandy. I asked her to be here tonight to help me with your birthday present."
I was confused because he had not told me anything about any present.
"I did not bring any presents. I can go out and get one..."
"You do not have to do anything Mandy. In fact, it would be very helpful if you did not speak a word until the end of the party."
I opened my mouth to ask more, but he raised his eyebrow and I decided to shut my mouth as instructed. Jessica grinned and gave a thumbs-up to Jim. She then went to the kitchen and came back with a basket full of hot, delicious smelling muffins. She held the basket in front of everyone and when it was my turn, she waited longer and unashamedly checked out my cleavage.
Jim closed his eyes after taking the first bite out of his muffin and moaned.
"This is fucking priceless. Your girlfriend is a magician, sister. I wouldn't mind having her as a lover if she was not a lesbian."
Jessica snorted.
"You wish."
Chelsea folded her arms and touched Katherine's foot with the tip of her shoe.
"Oh, I do not blame you. I wouldn't mind borrowing Katherine for a night either. I see so much lesbian potential in her."
Katherine smiled at Chelsea with coquetry, which apparently made Jim jealous. He pulled Katherine to himself and held her tight.
"Hands off my girl, you greedy dog."
This made all the girls laugh, and Jessica gave Chelsea a high-five. Jim pointed a finger at Jessica.
"This is all your fault. You are a bad influence on my meek sister. She would never talk back to me like that before she met you."
Katherine punched Jim's arm.
"Cut it off, you jackass. As far as I remember, your exact words were that you actually like the way Jessica is unleashing the wild animal in Chelsea."
This brought a momentary silence to the group, which made me more conscious of my slutty outfit. I really felt that I did not belong there and wondered what Jim was thinking when he told me to come. After a while, they made some more jokes and talked together as if I was not there. I was somehow grateful for that and wished to get out of this humiliating position as soon as possible. Jessica snuggled Chelsea and pointed to me with her chin.
"So, are you going to explain this phenomenon?"
"Oh, I almost forgot about her. Let me tell the story from the beginning. Some weeks ago, I was sitting in a bar, drinking my vodka and thinking about you two. I was worried that sooner or later, you bastards would try to steal Kat from me."
Katherine puffed exasperatedly.
"Which translates into that he was worried that there was something missing in your relationship."
"As I was saying, I was worried, so I was thinking about a solution to bring more juice into your platonic shit."
Chelsea frowned and protested defensively.
"Nothing is lacking in our relationship and there in not a single thing that I would change about Jessica. I am sure that she feels the same."
She looked at Jessica expectantly. Jessica hesitated for a moment, then nodded.
"There isn't anything about you that I would want to change either, honey."
Jim folded his arms.
"Ok, do not try to bullshit me. I have a very good instinct about these things and I can see that there are dark corners in your relationship. Let me put it this way; have you two ever spoken about your boundaries? Have you addressed kinky things like having a threesome, bondage playing, spanking, role playing and etc.?"
