After I finished high school I ended up choosing to study Electrical Engineering in Alberta, I moved from Regina to Edmonton not only for the quality of the school but also because I wanted to live a more independent life, away from my parents. To live the freedom of being able to be the way I wanted to be.

My name is Olivia, a light brunette 5' 7" tall, with straight black hair, light green eyes, slim, not that hot, medium breasts, and a smaller butt than I would like, also my legs are a little thin.

I have always been a good student, with the best grades in the schools where I studied. Studying is a pleasure, almost a diversion, especially mathematics. I love it! I had a few boyfriends and some very brief experiences with girls. I didn't know what exactly I wanted in the subject of sex, nothing caught my attention. Sex was not as attractive to me as it seemed to other people my age. I was under the impression at that time that I could live without having a relationship with someone. Whoever that someone was.

As soon as I arrived in Edmonton, I ended up sharing an apartment with some classmates in Parkallen, close to the university. We were five girls, each with her own room. It wasn't the best of worlds, but it was possible at the time, also because the neighborhood was very nice.

In the first semester, I was still getting used to the new life, the city, and the studies. The rhythm of the classes was more intense than in high school. But it was just a matter of adapting to the new pattern and that's what ended up happening to me.

My only problem was the Calculus I teacher - from the first day of class I knew that the two of us would not get along. It had to be a woman. Mrs. Emma Lund, the 'snake', as the students called her. She looked like something out of a Tolstoy book, no more than 5' 3" tall, a little chubby, with a round face, black eyes, behind black-rimmed glasses with thick lenses. She had hair the same color as her eyes, tied up on top of her head. She could very well pass for a Mother Superior of a convent. Even her clothes were old-fashioned; tight skirts below the knees, almost always with a long-sleeved jacket matching the skirt, everything in a discreet, lifeless color.

Emma was a formal person, of few words, a lady with an unfashionable accent. She was always angry, very angry, and, on top of it all, vindictive and unfriendly. Nobody knew if she was married, but there was a rumor that she had dated another woman a long time ago. I couldn't imagine any woman who could be interested in Emma, even the teachers seemed to be afraid of her.

My whole class had problems from the beginning of the course. No one got more than B's on the exams, and that was very rare. Only with me, it seemed worse. It made me sick just looking at her. And Emma didn't like me either, that's what it seemed to me. When I dared to ask a question she was rude to me. She was rude to everyone, but with me it seemed personal, bordering on humiliation.

I don't know why I never did anything for her.

While my grades in other subjects followed the pattern, always between A and B, with her, my grades didn't go past C. I would get the minimum grade to move on to the next subject. I suffered and was humiliated, but I would pass. Only it hurt my pride, much more than it did for other people. I was practically the only one who got upset with their test results.

Boring woman! The devil in person. Other exams came, and I prepared myself as much as I could to leave no doubt that I would beat the authoritarian dictator who thought she was the Calculus master. I was sure that I would prove myself. It would be a slap in the face for the authoritarian old woman.

I ended up with a D+ on the exam. I was shocked. I had never in my life gotten such a low grade. And I wasn't the only one, Emma warned that this way no one would advance, that there was no point in complaining to the Principal or even the Dean.

And I stood there stunned, trying to understand how I could have made a mistake on something as simple as the integral of a sine. How absurd! How could I have failed? That was the question I asked myself when Virginia decided to check the proofs. It was she who realized.

“Hey, Olivia! How could it be, that we got the same result and you got a zero? And not only that...”

We checked the exam papers. We checked with other students and my answer was the same as the others, but only mine had a red 'X'. I had the worst grade in the class.

“Talk to her. Go there and complain. Don't let it go unnoticed. Who does this woman think she is?”

Some students wanted to speak up for me, but knowing how Emma was, I thought it was better not to make it public at that moment. When the end of the class came, and I had the opportunity, I went to talk to her.

“Emma, I think there was a mistake in my grade. The question about the integral of sine...”

“I never make a mistake, dear.”

Stuffing the books into the folder on the table, she didn't even look me in the face.

“It's just that I compared the result of the question with other students and the result was the same. But only mine got a zero. Look.”

I showed her mine and Virginia's exam papers, and Emma held up the two sheets and sloppily adjusted her glasses. She shook her head as if to deny something, a sarcastic laugh on her face. I thought she was going to answer me with a dirty word, but it was better than I expected.

“Come to my room this afternoon, after two, and bring the exam papers.”

She looked at me with her usual hard eyes and marched off as if she were in a military parade. What a pedantic, arrogant little woman! I showed my tongue out at her.

“You look like a child. What did she say?” Virginia asked.

“She told me to take our exam papers to her room this afternoon.”

“At least it's something.”

“Yeah, at least she didn't send me to hell.”

“Then go, but you better get a vaccine against snake bites.”

***

I knocked on the door shortly after two o'clock in the afternoon. I felt like a little girl who had done something wrong. My heart was almost bursting out of my mouth, but the culprit of it all was that annoying Emma.

“Come in!”

“Excuse me. Good afternoon.”

Even sitting behind the desk, that short and unfriendly woman looked like a giant, which made me even more intimidated. I handed her the exam papers and she examined them with that sloppy look that she had. We were both silent for I don't know how long. I was standing there. The rude woman didn't even offer me a chair to sit on, and she was there examining the exam papers as if it was petulant of me to complain about one of her notes. I was losing patience, dying to get out of there. And she seemed to enjoy the uncomfortable situation that I was getting in front of her. I still didn't understand why she treated me with such contempt.

“You see, the answer is the same on both tests there are at least three questions with the same result.”

“I know, I know. I've seen it.”

I didn't know whether to be angry with myself or with the annoying teacher. I wanted to punch the unpleasant woman in the face. That's when I got a surprise. Emma took off her glasses and put them on the table. She didn't even look like the same person. It was like she was ten years younger. She looked different, I don't know what magic that was. She became prettier, more interesting. She scribbled something on the test. And I gained the courage to speak again.

“I studied hard for this exam. I was sure that this time you would give me a better grade.”

She laughed at the way I spoke. It sounded like a mother laughing at her daughter.

“You're the kind of girl who likes to be top of the class. You are too young, you don't understand the signs of life. Dedication alone is not enough to get an "A" grade. It takes a little more...”

She laughed, closing her lips as if admiring my body. I didn't understand what she meant. And like the fool I am, I decided to ask the mysterious old woman.

“A little more of what?”

“Attention. Admiration and respect for those who know more than you do. At least that's what you should do.”

She stretched out her arm and handed back the proofs. I pulled out the papers and checked the grade. My goodness! I almost screamed. An A-! It was my best grade with her, the best grade in the class.

“Wow! Thanks, Emma! Thanks!”

She put her glasses back on and frowned. She was back to being the same ugly pain in the ass.

“Professor Emma.”

“Teacher, yes ma'am. Thank you! See you later.”

I turned my back and ran towards the door. That woman had the power to make me nervous, even without looking at her.

“Come back more often, Olivia. It will do you good, to ask for some advice, maybe.”

“I will, I will. Bye!”

I left, closing the door and running as if escaping from a prison. I went to the library to tell everyone the news. Nobody believed that the snake had changed my grade. Even the seniors didn't believe what they saw.

“Wow, girl! I never heard of Emma changing anyone's grade. Everyone is always afraid to face the Fascist. How did you do it?”

“I don't know. All I know is that she didn't even argue. There was nothing to argue about either. The answers were the same, you only had to compare the proofs.”

“There have been people who tried and failed. Not even complaining to the board helped them.”

Anyway, it came as a gift. I was relieved as if a weight had been lifted from my back. But I just couldn't get out of my head what Emma had told me about her invitation. I found it strange and at the same time I was getting curious. Aside from her transformation in front of me, she seemed like a different person. Someone more interesting, fascinating. I didn't know who she was.

But the surprises didn't stop there.

Days later, in the next class. I confess that I hadn't even paid attention when Emma came into the room. I was writing the notes of the previous class, and it was Emily who caught my attention.

“I can't believe it. Look, Olivia, look at the snake!”

“What happened?”

I was still looking at the notebook. The whole class was quiet, which was a rarity, and everyone was looking at Emma. I looked and was amazed. Rather than the usual Emma, it was the other version, the one who had revealed herself to me in her room. Only younger, and even more interesting. Without her glasses, probably wearing lenses, she had two loose strands of hair falling in front of her ears, and her lips were painted red. Her clothes had not changed much, but there was a flower on the lapel of her jacket.

“What happened? Did she get a crazy guy with a thick dick to eat the old woman? Do people like snakes?”

“What did you say, Mr. Gustav?”

“Nothing, I said nothing. Professor.”

“You better not have said anything at all. After all, if I were you, I'd be more concerned with studying the course material than chatting with your classmates.”

Emma shot a glance at Gustav who was sitting behind me, put her fingers in the front pocket of her dark green jacket, and looked at me. It was just a moment, an instant that seemed to freeze time. She stared at me with her glowing eyes, and I was mesmerized by her figure. It looked like a boyfriend thing. And I never had a 'girlfriend', just a few kisses here and there, just to experiment. I knew that my interest was in men. At least I thought it was. Even though none of them had caught my attention for quite some time.

I was charmed by her. I found my own silly ideas funny, imagining a woman like Emma being interested in a silly girl like me. Even rejuvenated, Emma acted as usual and gave us a mountain of work to study. In this, she was still the same, sadistic and arrogant as ever.

It was the same day, that day, Friday afternoon. A coincidence. I was leaving the library to have a snack, and she was coming from the other side of the corridor in the opposite direction. I had no way to dodge, there was no corridor, no ladder, no hole to get into. The two of us were walking toward each other. The corridor seemed a kilometer long, and I could only hear the sound of her heels hitting the stone floor. I frowned, trying not to stare and thinking about what to say.

“Teacher,” I said. My voice was almost inaudible.

“Good afternoon, Olivia.”

She walked by and I turned around, I don't even know why I turned around, but I turned around and spoke.

“I like your new look. You are much prettier, Emma... I mean, professor.”

She smiled and her face lit up like a sun.

“You like it?”

She smoothed her hair over her shoulders.

“Everyone liked it. You look younger, prettier.”

“Pretty! Exaggeration. Really? But your compliment has brightened my day.”

We both stood there in the middle of the empty corridor. Her gaze locked on mine, and I laughed without really knowing why. Not understanding what it was all about. It was Emma who pulled me back from the clouds.

“Do you have an appointment tonight, girl?”

“What?”

“Do you want to have dinner with me, the two of us? I know a restaurant, it's been a long time since I've been there. The Dominus, ever heard of it?”

“No, I haven't.”

“Very cozy, very interesting. The food is delicious and wonderful. I used to go there a lot, but I haven't been in years. I was left without company. Do you want to go? I'll pick you up. Give me your address and cell phone.”

She continued to be as imposing as ever. I tried to imagine an excuse, but nothing came. It was so strange, so unusual, I didn't know if it was pure friendship or if she was flirting.

“I don't know if I'm going to be good company, Emma... Teacher.”

She buttoned the button of my blouse without asking permission. She looked at me with her black eyes, two black balls appraising me.

“If I invited you, it's because you're the person I want. If you weren't, we wouldn't even be here talking to each other. So, give me your cell phone and I'll call you. Can I pick you up at eight? I'll text you first.”

***

We arrived at Dominus at almost half-past eight in the evening. It was an elegant, exquisite, almost dimly lit environment. All the tables had blue napkins and a glass jar where starry candles floated lighting up the water. The walls reminded me of exposed brick, or something more rustic. And hanging from them were pictures of different sizes, lit by spotlights at various angles. Black and white photos of various people, sometimes a focus on eyes, hands, a mouth, a breast, the curve of a waist, the hips of a man. Naked women in heels and shiny stockings up to their thighs, holding long whips, kneeling men with muzzles pulled by girls dressed in elaborate masks.

I was struck by the waitresses, as there were no men. There were only couples, all women, and many mature women accompanied by young ladies.

“Let me see. I'll have a Blue Sky, how about you, Olivia?”

I looked at the menu, wondering how much everything would cost. I had no idea what to choose, there was nothing on the menu that looked familiar.

“How about a Midnight Special?” Emma said.

“We also have the G-Spot,” suggested the waitress.

“Better the Midnight. That's fine,” I said, embarrassed.

“In my day there was no such thing as the G-spot, I'll taste it later.”

Emma giggled, and it was obvious she was making fun of me. She liked seeing me turn red like a strawberry.

“Has it been a long time since you have been here? I mean... Teacher?”

“No need to be so formal, Olivia. We're not in college and even there I'm known by other names, aren't I? Usually, I'm the snake, the rattlesnake, the serpent.”

“Wow, I didn't even know that," I protested. She didn't believe me.

“Yes, it's been a while since I've been here. Not much has changed, just the photos, which are now much more daring.”

And then she started telling me about her life. As she talked, I did the math on how expensive that dinner would be. I was going to end up in jail or naked. I prayed that she would offer to pay. Out went the drinks, and in came different types of bread. After that came the garlic soup for her and the pumpkin soup for me.

“Bring me an Argentinian Cabernet. Olivia, is that to your taste?”

As if I was going to say no! She was the one who chose and commanded everything.

Time went by, the two of us were drinking and Emma was getting more and more joyful and loose. She told me stories about her childhood, her studies at Princeton, her doctorate, and her marriage to her late husband.

“Have you chosen dinner yet? I'll have the fish.”

“Fish! I'll have that, too. Whatever you choose, Emma.”

My head was spinning from the effect of the drinks. I couldn't even control myself not to call her Emma. She didn't pay attention to that ridiculous etiquette anymore either.

“I'll have the salmon with honey and mustard. Choose the one with asparagus, I think you'll like that, Olivia.”

After we ordered, Emma was laughing and talking more than ever. It was surprising to imagine Emma married to someone, even more so when the intimate details of a long marriage came up.

“What do you mean, a cage? You put your husband in a cage?”

“Only when he didn't obey me. I had to make it clear who was in charge. But Mark loved it. It took years before he accepted what he was, a masochist, and invert. But it wasn't his fault only, it was me who, deep down, didn't want to accept who I was.”

“Inverted?”

“A man who accepts the penetration of a woman. Who likes to be possessed, so the orgasm comes much more intense. Fingers massaging the prostate or a penis sodomizing the macho man.”

It was all a whirlwind of information, and I was getting carried away by her conversation, getting into the rhythm, and more and more curious.

“And what was it that you didn't want to accept?”

“That I am a domme. I'm not much of a conventional person, but deep down I'm what they call a dominant. A master of sex, but I don't follow rules. I make my own rules.”

“This started there, in Princeton?”

“There, then we came here. And that's when Marta came into our lives.”

Emma laughed as if confessing a secret. She took a bite of the salmon and put her fork on the edge of the plate, chewing and analyzing my reactions. I looked at the plate, not sure if I had heard what I thought I heard.

“Marta? Who is Marta?”

“Are you sure you want to hear? Can I trust your discretion?”

“Of course! Don't worry.”

I took a sip from my glass, trying to hide my discomfort, the feeling that all this was deeper and more intimate than I could have dreamed.

“It was intense for me. Those years were remarkable. The three of us experienced everything. Without limits, without restraints, living what our bodies asked for. It was the purest sensation of horniness, even more so in a threesome. But I was always in control of both of them.”

“And what did you do with them?”

“What their nature demanded. What it took for them to feel satisfied. They both liked to be dominated, subdued, and possessed. And I was discovering that I loved doing all that.”

“Was Marta a masochist?”

“Both, submissive. But we only met Marta here. She was young, twenty years old. She was a student like you when she started to come to our home. It wasn't long before Mark and I were living a new reality. It didn't take much for Marta to discover us.”

“And she agreed? I mean, did she accept fast like that?”

“She was very curious. She spent some time watching us, hiding behind the door, behind the curtain. We knew, most of the time. It was Mark who found out, he saw her wet panties in the bathroom. He told me and suggested it.”

“You two with her?”

“No, it was me. Mark was traveling on business and I asked Marta to stay with me one weekend. I made her comfortable, showing her that it was safe. And she opened up, confessed. Then she just had to accept herself. Marta was a wild mare. A delight to masturbate, I left her naked and wet in the middle of the room the first time. Sorry, I talk too much, it's the effect of the drink.”

“Not at all! And then you agreed to share her with your husband? Didn't it make you jealous?”

“There is no jealousy when you accept that pleasure is the limit. And they needed it. The submissive always need us. And when one of them made me annoyed, I locked them in the cage. Most of the time it was Mark. The bastard liked to watch me with our mistress, he was more a voyeur than a masochist. She was the perfect type for a dominant like me. The girl turned into someone else between four walls, like a form of madness.”

“Didn't she ever sleep with him?”

“Of course she did.”

“In front of you?”

“Usually the three of us together. You can't even imagine.”

“So tell me.”

“No! Not today. I told too much, much more than I should have.”

“And when did he die?”

“About fifteen years ago.”

“And Marta still lives with you?”

Emma looked sadly at her hands stretched out on the table, the hands rubbing together.

“Marta eventually got married, moved away, and went to live in Spain. She has a beautiful adopted daughter with her new wife.”

“How long has it been?”

“After Mark passed away, our relationship didn't last very long. I suspect that she missed him more than I did. She was never the same again.”

“And you were alone, there was no one else?”

“I became disillusioned. I hid from myself. No one else was worth it... Not until now.”

She caught me off guard. We stared at each other. Behind the glasses, her eyes were shining, her lips tight, and my face was burning. This wasn't a hint, it was a punch in the face. I was getting more and more curious, but I couldn't help being afraid. This was going faster than it should have. Emma was stranger than I imagined.

Thankfully the waitress broke the mood by removing the dishes and cutlery.

“Would you like a dessert, a coffee?”

“An espresso.”

“For me too.”

I looked at the time, thinking of a way to leave, it was over ten o'clock.

“This is all very crazy. I never imagined that you were like this?”

“Never kissed a little friend? Never rubbed a pussy?”

“No, I just kissed and hugged. Pure curiosity. I never really liked it. Even more...”

“Even more what?”

“Even more, someone like you. I don't know if I... I don't know... I guess I'm not like Marta.”

“I know how it is. Maybe because you haven't allowed yourself yet, haven't discovered yourself.”

“But I don't think I am passive. A submissive, that's not my style.”

“Marta told me the same thing. Coincidence. You have her eyes, her laugh, her way... But that's ok, I didn't bring you here to make you uncomfortable. It's the drink, don't worry.”

The espresso came, and then the bill arrived. Oh! What a relief! Emma didn't even let me look at the bill. She paid for it on her credit card. She didn't seem disappointed, I thought she turned out better than I expected. We left the restaurant talking about the course, the students, and the professors.

It felt as if it were a dinner among friends. I was relaxing at the change of subject. I knew that I was liking Emma more and more, but not as she had suggested. I wanted nothing more than a friend, and a confidant.

We arrived at my sorority after eleven o'clock.

“Well, Emma. I loved the dinner. I loved the company and the conversation. It was more than I expected.”

“Maybe we can do it again some other day?”

“Yes, maybe. Who knows?”

“I count on your discretion, Olivia. Everything I said was because I trust you.”

She put her hand on the headrest of my seat, instinct made me fear a kiss. I opened the door immediately.

“Don't worry, I'll never reveal something like that. We're friends now. Bye, darling! See you on Tuesday.”

I got out of the car and walked quickly towards the stairs of the building. I climbed the steps and put the key in the latch. That's when I heard Emma's authoritative voice behind me.

“Olivia!”

I just turned around, I didn't have time to respond. As she climbed the stairs, Emma seemed over six feet tall. She looked at me steadily and pulled me by the back of my neck. It was a crazy thing, a magical thing. A tongue kiss, our mouths glued together. I was being invaded by Emma, I was being possessed by the naughty tongue of my Calculus I teacher. Unpleasant, a little fat, a pain in the ass!

Emma licked the roof of my mouth and bit my tongue. She invaded me with a tongue as if it were an erect penis fucking my mouth. She became more and more thirsty and crazy. And I accepted to be kissed by the teacher. I felt my breasts getting hot and hard.

I was being inoculated by a ravenous snake. I was submissive surrendering myself to Emma's pleasures. My boundaries were falling, my mind was opening. I no longer knew who I was. All I asked was that the kiss would never end.

I opened my eyes only when her lips were parted from mine. There was a thread connecting our mouths. The two of us breathing together, unique.

“Good night, Olivia.”

There was a tear in the corner of her eye. Emma walked down the stairs facing me, without taking her eyes off me. She took a few steps like this and turned walking towards the car.

I tried to speak, but my voice caught in my throat. My body was shaking, I was vibrating from head to toe. I stood frozen at the top of the stairs watching the car drive away and disappear down the street. My head was spinning in a whirl, I felt short of breath, and no one had ever kissed me like that.

I didn't know who I was anymore. Who I was becoming.
