This is a true story that happened in the early 90's in some midwestern university.
We met when I was in my first year of grad school and she had started a postdoc. Sarah was from New Zealand via England, and she had graduated early. She was what is called in French a "garΓ§onne" very thin and androgynous.
She was working in a field close to mine and so she naturally joined the grad student group, probably feeling more at ease with us than with the professor group. We shared some tastes in music, and we exchanged a few CD's along with some coffees. I was attracted to her, but I was seeing someone I had met prior to meeting her. She was older than me and I did not think she had an interest in me, being in my first year of grad school.
Our relation got a bit stronger; we were doing more and more things together (my girlfriend had a job where she often worked on weekends).
These were the days before internet (early 90's) and finding someone with similar kinky tastes was not an easy feat. I did notice once or twice that she had used masochistic in some sentence, and my kinkydar lit up.
She was for a while the sole focus of my masturbation fantasy.
We did more and more things together (apart from the usual group) and I started to wonder if my interest in her was not reciprocated. After a movie, we were chatting and I did mention to her that I was feeling something between us, and she confessed the same, telling me she had been quite pissed off after finding out I was seeing someone.
We left it at that that night, and we had coffee the next day, I invited her to my place, where we had our first kiss, we started on the sofa and moved to the bedroom, where she dried humped me while kissing. I asked her if she came, and she laughed and told me it would be her secret.
We then continued to kiss and pet, and at one point I put my face on her crotch and inhaled, to start kissing and licking over her pants, she positioned herself over me and dried humped my face, I loved it and just used my face as to bring her pleasure.
We were constrained for time and as we got off the bed, she whispered in my ear, "I did come this time."
I was planning to end things with my girlfriend that weekend, but some family drama got in the way, and I decided to put things on pause with S.
We were now in a much flirtier relation, and I had asked her to tell me about her fantasies, which she had refused telling me she would share them with me after we had a proper fuck.
I did let the subject drop, and things went along until we met at a party, where we started chatting and the alcohol helping, I asked her once again about her fantasies, and again she brushed me off reminding me of the deal.
I pleaded with her to have a little snippet of those fantasies, and in a magnanimous way, she told me she was into role reversal, II confessed to sharing this taste and we started to have an open-hearted exchange about our fantasies.
We were quite compatible; I described in detail some of my fantasies about her and she confessed having dreamed I licked her during one of the classes we both attended.
During that time her right hand discretely dropped on my tie and stated to caress my cock and balls, with a lot of discretion. She talked of her desire to have me obey her and to try to whip me.
I asked her if she had ever done any whipping to which she answered that I would be her first.
At one point someone asked us to come in join the dancing, and being not into that kind of dancing, I politely declined, but S looked at me and told me
"You will dance."
So, I smiled and got up to dance, acting like it was no big deal, trying with some success to hide my erection. But we both knew that a game had started and that she had the leading hand.
Once we were both seated, she asked me if about my experiences, so I told her about my few kinky times and in a braggartry tone that I had licked some girl's arse hole. She then looked at me and asked me in a serious tone,
"If I asked you to lick my arse, would you, do it?"
I thought about it for some time, wondering if I was going to submit to her, then I made up my mind and answered,
"Yes, I would".
She then got up and told me to meet her in the bathroom in a minute. I did so and once in, she told me to kneel, and lowered her pants and nickers, she then presented her arse to me and told me "lick."
I did so with pleasure and excitement, licking around the hole, then making my tongue pointy, penetrating her, she was fucking my face with her arse as she was caressing herself.
She came fast and told me we should go somewhere more private to continue this.
We walked out of the party and went on a beach by the lake which at that time was completely deserted.
We proceeded to kiss and pet each other, and I recall she kept on telling me how sexy I was, we lost most of our cloths and I invited her to sit on my face, which she did without having to be asked twice.
She proceeded to fuck my face with complete disregard for my breathing, I had to synchronise my breathing with her hip movements, it was intoxicating.
When she dismounted my face, she asked me,
"Do you want me to whip you?"
I wanted to be whipped, and so I answered
"Please Sarah, whip me as hard as you wish."
She took my belt off my pants, told me to strip completely and proceeded to give me a harsh whipping on the butt.
I remember the intense look on her face as she whipped me, I moaned and encouraged her to keep on going. It was not painful as I was very excited, but it was a lovely feeling, being at her mercy and watching her as she trashed me.
At a point she turned me over on my back again and sat back on my face, I knew what I had to do. I guess she felt the excitement too, and had me to deal with that.
We then went back to some kissing and fondling, I did tell her she could be as rough as she desired with me, and she playfully squeezed and slapped my cock and balls, at one point, she was squeezing my cock very hard, and she was impressed that she could feel me throbbing.
She then told me I was going to have to control myself, she was going to fuck me, and I was not to come. I was sitting on the ground, and she mounted me and proceeded to fuck me.
I was not allowed to move, and a few times I had to tell her to slow down or the unavoidable outcome would happen, she did so, and after a few of these alerts I got to a state where I would not come, she fucked on for some time, and I am not certain she came, but she enjoyed fucking me while I had no pleasure.
Eventually, she unmounted me, and checked I had not cum, satisfied with the lack of cum, she had me licked her clean, front in back. This was more of a ritualistic licking than pleasure giving one. I obeyed and worshipped at her altar.
She then had me squatting on all fours and white one hand on my balls, and the other on my arse, she made me promise that I would give her my virgin arsehole. I did promise and she presented two fingers to my face and told me to suck, and she then finger fucked me, telling me that that was a preview of what I would get.
We were done for the night, and we got dressed and proceed to leave, but she grabbed my head and started to kiss me again, and then she told me
"Suck me again."
I got on my knees, and she lowered her pants and started to fuck my face from a standing position, when she came, she told me to keep my mouth open.
She looked at me in the eyes, standing over me and asked, "will you do anything I ask?" I did tell her I would she then smiled, and she told me
"I am going to piss in your mouth, and you will swallow all of it"
I answered
"Yes, Sarah I will do as you wish."
She began to piss in my mouth, slowly stopping when it was full and telling me to swallow, I was like a dear in front of a taillight, I could only obey, the taste was not revolting and obeying her like that was intoxicating.
When she had finished emptying her bladder in my mouth, she had me clean her again front and back, and as we parted, she told me that next time I kissed my girlfriend, I should think of her piss in my mouth.
That night, I couldn't sleep. I was incredibly aroused, masturbating all night without any relief. It felt like I had finally experienced something I had been waiting for my whole life. I didn't get a wink of sleep and dragged myself through the next day, being unproductive at work. Fortunately, it was the weekend. I did manage to sleep the following evening, and on Sunday, I went for a long run to try to escape the constant sexual excitement I was feeling. I only partially succeeded in that endeavour.
On Monday, I received an email from Sarah, which simply said, "Coffee?" I agreed, and around four o'clock, we met at our favourite coffee shop. She was already seated when I arrived, and I asked if she wanted another drink," Another espresso" she said. I brought the drinks and heated myself at her table, there was an awkward silence, which she broke by asking, "So, how do you feel about Friday night?"
