Twenty-Three: Twin Sisters Discover Lesbian Ballet T. Ropex
I was ready for my next day of vacation. I was so eager for whatever the AI had in store for me. My vacation through Earthling Dreams was living up to the reputation and the cost. So I stretched and was ready to watch more humans forced to act out their own live re-creations.
Why would they produce those videos if that was not an accurate depiction of their society?
“Yes, it is illogical,” said the AI. The Fantasy Assist Ver 4.27. “This is why humans are a lower species. It is no wonder that vacations on Earth were only recently approved. Well, I have located the next scenario.”
“I am ready,” I said, eager for it.
“Then we are off.”
Ingrid Persson
I yawned as I walked down the sidewalk with my twin sister Sigrid to our ballet practice. We were training under Madam Katarina. I liked ballet, but she was a very easy instructor. She didn’t push us. Not like our last one.
She was a complete nightmare. A task driver. It was why my sister and I quit and found a new teacher. Sigrid was staring at her phone as she walked, her gym bag slung over her shoulder. We were identical girls. A pair of blondes, tall but slender.
We were, perhaps, too tall for ballet. You had to be a slender thing to be a proper ballet dancer, and if you grew tits too big or put on too much weight, you were out. At least, that was what the old teacher said. What a bitch.
We were nineteen now. Our growth spurt was over. So we weren’t getting any taller. Our last teacher—I didn’t even want to think that bitch’s name—had yelled at us over our height. As if we could help being “towering oaks just blundering around.”
I opened the door for my sister. We headed into Madam Katarina’s dance studio. We were her early students. I yawned as we entered the dance hall. It had the warm-up bars to the right by the mirrors. On the other side were seats for parents to watch as their children practiced. Not that there were any of those here.
We were the only students right now.
I threw down my gym bag and sat on the chair. I pulled off my hoodie. I had my leotard on already with my tights covering my legs. Mine was pink with purple tights, opposite of what Sigrid wear. She yawned and stretched in her purple leotard. She sat down beside me, stretching.
We pulled on our ballet shoes. They were stiff and tight, binding our feet together. I could stand on the point of my toes with them on. It still hurt. It would always hurt, but that was the “Price to perform beautiful art,” or so said our last teacher.
“I am so tired,” Sigrid said, her blonde hair pulled back in a ponytail.
“Mmm,” I said and rose.
Out from the back, Madam Katarina appeared. She wore a light-blue leotard and gray tights. She was a slender woman in her forties. Still beautiful, but fading. Her black hair was cut short in a rather butch fashion like she was a lesbian or something.
Not that I thought she was. She certainly never leered at us or hit on us. That other bitch, though ... I was certain she wanted to dyke out on us at times. That she was just biding her time for the moment to prey on us.
What a terrible cunt.
“Welcome, welcome,” said Madam Katarina. She had a soft voice and a gentle smile. “Let’s get warmed up.”
“Yeah, yeah,” Sigrid said.
I smiled. I was more positive than Ingrid. We were identical twins, but our personalities had slowly differed over the years. We were so close as children, but now we had a balance. I reached the bars ahead of her, smiling at her to encourage her.
She rolled her blue eyes and joined me.
Madam Katarina took her place beside me, facing me. She smiled at me and said, “And let’s warm up, girls!”
As we started stretching and extending our legs, a man appeared on the other end of the room. A boring, nondescript man that I didn’t care about. I just ignore him and bent my legs or extended one, holding onto the bar.
We went through the same motions as every class with Madam Katarina nodding along. She was so gentle. None of that yelling. When one of us wasn’t quite perfect, she just gave us a nudge. Asked us to do it again.
“Just extend the leg a tad farther, Ingrid,” she told me. “There you go. You feel the difference.”
“Yes, Madam Katarina,” I said. The old bitch would have screamed at me until I was terrified.
“Good, good,” she said. “And Sigrid, you want to keep your back straighter. There you go. Just like that. You’re doing great.”
“Thanks,” Ingrid said.
After we were warmed up, Madam Katarina went over to the dock and put her phone in. Some classical music started playing. I knew the song and the dance that was supposed to go with it. I moved not position and rose onto my tiptoes.
With Sigrid, I danced. We moved around the room, our bodies flowing as we went through our dance steps. I flowed into a grand battement a` la seconde to pose called the arabesque, standing on one leg in a demi-plie´, a slight bend in my knee. I danced en pointe, on the tip of my toes, for a bit, before going into a pas de cheval.
“You’re doing wonderful, ladies,” said Madam Katarina, “but mind your demi-plie´, Ingrid. You need just a slight bend of the knee. You don’t want to lose balance.”
I nodded and did a petit saut, a small jump.
“Sigrid, you have to go lower for a grand plie´,” Madam Katarina said next. “That was barely more than a petite plie´. I know you can do it. Yes, yes, like that. Very good. You’re both doing so wonderfully.”
The man was watching us. I ignored him, but he seemed to be waiting.
I performed a releve´, rising from demi-plie´ to en pointe on one foot. I turned in place from that position and came back down, sweeping my arms up into the air. A gleam of sweat coated my body as I moved through the forms.
I felt so free. I was so happy right now. I was dancing.
“Your form is very good, ladies,” Madam Katarina said. “But you can be a little better. Backs a tad straightened. That’s it. You’re improving so much, ladies.”
I beamed at her. So glad that my sister and I found a supportive teacher.

I watched the girls dancing. They moved in ways I had never seen before. I was entranced by their beauty. I didn’t need them to become lesbians yet. I just wanted to see them moving. They rose onto their tiptoes.
“How do they do that?” I asked in awed.
“They have worked hard and trained hard,” said the AI. “The scenario is ready to be implemented.”
I nodded, watching the girls twirl. They were identical to one another. I had never seen two humans who were mirrors of each other. “Did they become that way through surgery?”
“They are twins,” said the AI. “Human reproduction is primitive and occurs entirely in the woman’s uterus. Early after insemination, the zygote had an error and divided in half, forming two blastocysts that became two fetuses who have the same DNA. They are identical to each other on the genetic level, though thanks to environmental effects, they have minor phonological differences from each other, including in their behavior.”
“Fascinating,” I said. “That’s even more incestuous than just if they were sisters.”
“Twincest is the portmanteau that was created to describe it by some Earthlings.”
I was eager, watching the girls dance past each other. They both jumped into the air, their legs scissoring out, before they landed on their tiptoes and spun about. I shook my head at the skill, but ... I wanted to see them fuck more than ever.
“Adjusting the scenario,” the AI said.
Sigrid Persson
I swept into a rond de jambe, turning clockwise on one foot en pointe, my other leg moving to keep me spinning in place. I came out of it facing my sister. She did the same, panting. The music ended. Our dance over.
“Very good, ladies,” said Madam Katarina. “Just a few points.”
I glanced at her. She was such a better teacher than our last one. Ingrid was happier around her, and I didn’t have to cry in the corner every five minutes. I smiled at Madam Katarina as she walked over to us. The slender woman wore a warm smile that...
I blinked as she had huge breasts that were barely constrained by her leotard. They spilled out the sides of it. The blue leotard was cut narrow in the crotch, cupping her pussy and her thick bush. A few golden strands of hairs spilled out. The back vanished into her butt-crack. She held a riding crop in her hand. She wore her blonde hair pulled back into a tight bun.
Wait, wait, wait, what is going on? a voice whispered in my mind. Why does she have a riding crop? When did her hair become blonde?
“That was terrible, ladies!” Madam Katarina hissed, her big tits jiggling. She was so skinny, but had massive breasts. She looked so top-heavy. More a bimbo than a ballet dancer. She smacked the riding crop into her hand. “Do you know how disgusting that was. You danced like sluts. Harlots. Not pure ballerinas.”
“Hey!” I objected, still feeling off about that. “Don’t say that about my sister!”
Madam Katarina glared at me.
“Sigrid,” Ingrid whimpered. I glanced at my sister. She wore her purple leotard that was cut like a thong in the front, cupping her shaved pussy. We had to keep our pussies shaved per Madam Katarina’s orders. “What are you doing?” My sister had plump lips and big breasts. They were enhanced by surgery.
Why does my sister have a boob job? that stupid voice asked again.
How dumb. She got one with me. It was a requirement for Madam Katarina’s. I shook my head, so confused about why I was even objecting. I had to be obedient to Madam Katarina’s. I drew in a deep breath, my big tits about to break free of my skimpy leotard. I wore pink thigh-high stockings that matched my sister’s purples.
“Bend over,” hissed Madam Katarina.
Ingrid flashed me a commiserating smile. I turned around and bent over. The back of the leotard went through my butt-crack, leaving my butt-cheeks bare. I had never dressed like this before training under Madam Katarina.
“Women should show off their tits and asses while dancing,” said Madam Katarina. “So pure, they do not care how they turn on the men watching them for they do not care about men. They care about only being beautiful for women.”
“En pointe,” hissed Madam Katarina.
CRACK!
Her riding crop smacked across both my butt-cheeks. I yelped in pain and rose up onto my tiptoes, my big titties jiggling. I had to hold my balance through my spanking. I blinked back the pain burning across my rump.
“You are a ballerina, not a slut!” she hissed. “Not a whore who slouches. You stand proud.”
“Yes, Madam Katarina,” I whimpered, my toes already hurting, but I could hold the pose.
CRACK!
“Are you a slut?” she demanded. “A cock-hungry whore that wishes to please men!”
“No!” I gasped.
CRACK!
“I do not believe you,” she said.
CRACK!
“You move with all the grace of a pole dancer! A whore who strips and dances for money. For male attention!”
CRACK!
“Is that you?” she demanded.
My ass burning from the stripes, I gasped out, “Never! I would never be a pole dancer!”
CRACK!
“Then what are you?” Her hand gripped my burning rump. “Huh? What are you, Sigrid? A sow or a swan?”
“A swan, Madam Katarina!”
“Then show me!” Her hand pulled away.
CRACK!
“DANCE!”
I leaped forward into the dance, my tits heaving my leotard. They bounced so much, they escaped out the sides. They were exposed, my nipples hard. I spun in place, my back straight. I performed a perfect rond de jambe and swept into a temps lie´, sweeping from the fourth, fifth, and second positions.
My boobs bounced, my ass burning as I swept around the dance room. Madam Katarina walked me, my ballet shoes sliding on the polished hardwood floor. I spun around, my tits smacking together. My pussy burned so much, my crotch wet.
Ingrid watched, nodding.
She was so supportive of me.
“You call that better?” hissed Madam Katarina. “Show your sister how to be a swan, Ingrid!”
Ingrid swept out into the dances. She flowed around me, coming back after executing a flawless pique´ turn en pointe. Her tits burst free of her skimpy leotard top. They were magnificent breasts. So big and firm. They bounced as she moved, her nipples hard. My pussy dripped juices as my sister flowed past me.
Her butt-cheeks clenched as she flowed. I wanted to slap my twin sister’s rump.
“Better,” said Madam Katarina.
SMACK!
She slapped my sister on the ass as she passed, giving her butt-cheek a squeeze. I whimpered in envy as Madam Katarina purred, “Mmm, firm.”
Ingrid just whimpered and lost her step. Madam Katarina did not look happy at that. My sister caught herself and moved through first and third positions into a saute´, a jump where she kicked her legs out. She landed en pointe and spun around.
I stared entranced by the beauty of my sister as Madam Katarina moved around behind me. My heart pounded as she slid her arms around me. What was she doing? Ingrid moved with such grace, her bare tits bouncing as she performed another saute´.
“Mmm,” Katarina purred. “Look at that swan flowing.” Her hand slid down my stomach while the other cupped my tit. She squeezed it. “You enjoy watching a swan, yes?”
“Yes,” I whimpered.
“And that she’s your twin sister only makes it more exciting?” she asked.
I nodded as my sister spun up onto her right foot, her left leg bent. A perfect rond de jambe. Madam Katarina’s hand slid down to my crotch. She cupped my pussy through the fabric of my leotard. I groaned as she stroked up and down me.
“Yes, yes, women appreciate a beautiful swan,” cooed the dominating instructor. “Mmm, you see the beauty, don’t you?”
“I do,” I whimpered as she pulled my leotard to the side and stroked me. “Madam Katarina?”
“You and your sister are ready for your ... next level of training,” she said and pinched my clit. “Right?”
Pain and pleasure burst from my bud. “Yes, Madam Katarina!”
My sister kept dancing as I shuddered there, so turned on by the way the dominating ballet instructor caressed me. She made me feel so naughty. I squirmed there as her fingers stroked around my clit. Her other hand kneaded my tit.
This warmth swept through me. My twin sister danced on, unaware that I was being molested by the ballet instructor. I shuddered there at her touch. Her fingers danced over my clit, pleasure sparking through my body.
I whimpered as she slid her fingers through the folds of my cunt and found the entrance.
She thrust into me.
“So tight,” she purred. “Mmm, we’re going to have to stretch that hole out.”
“Y-yes, Madam Katarina,” I whimpered at her touch. “I ... I...”
She plunged her fingers in and out of my cunt as my twin sister twirled. Her blonde ponytail whipped behind her. She jumped several times, a series of petit sauts. She looked so sexy. Her tits heaved. I whimpered as Madam Katarina ground the heel of her hand on my clit.
Her other hand found my nipple. She pinched it, her fingernail biting into my nub. I hissed at the pain and trembled, my pussy clamping down on her fingers. I gripped them as she worked those digits in and out of my cunt.
She drove me wild.
I groaned at that. My eyes rolled back into my head. My sister danced passed us, still unaware. Still so sexy. She kicked her leg up as she rose en pointe, her cameltoe on full display. My mouth watered at the sight.
What is wrong with me? that voice asked.
“Mmm, what a delicious sight,” cooed Madam Katarina. “You want to devour your sister. That beautiful swan.”
“What?” I whimpered. That was incest. Lesbian incest.
“Do not lie,” hissed the dominating instructor. She pinched my nipple and ground the heel of her hand on my clit. Pleasure and pain sparked through me. “You want her. Desire her. Speak the truth. Be a swan, and not a sow.”
“I do,” I whimpered, my sister dancing away from us, her butt-cheeks drawing my attention. I wanted to do things to her. I craved her.
“Yes, yes, you’re a swan, too,” she moaned. “Cum for me, little swan. Be beautiful and cum!”v
My sister spun around and gasped. Now she witnessed what was happening. Her eyes were so wide. I shuddered as the ballet instructor pinched and twisted my nipple. Her fingers thrust into my cunt so deep.
“Sigrid,” Ingrid whimpered.
“I’m a swan!” I squealed and came.
My pussy convulsed around Madam Katarina’s fingers. I bucked through the delight. She licked my earlobe as the pleasure swept through me. Stars flashed across my vision, dancing around my gorgeous twin sister.
Ingrid moved closer, her eyes so wide. Her fair cheeks blushed. Her nipples poked out hard. I moaned, staring at her big breasts. I wanted to bury my face between them. I shuddered, my cunt writhing around the instructor’s fingers.
“What are you doing to my sister?” gasped Ingrid.
“Training her to be a swan!” Madam Katarina said, ripping her fingers out of my cunt. “Do not move! Neither of you!”
Ingrid flinched as I trembled, my body quivering through my orgasm. I felt so good. The waves of ecstasy surged through me. I trembled there, my back arching. My boobs jiggled before me as pussy cream ran down my thighs.
“Sigrid,” Ingrid whimpered, my twin sister staring at me. “She ... she...”
“Yes,” I moaned.
“I am going to do more than finger her pussy,” Madam Katarina said.
My twin sister glanced to the left and gasped. She clapped her hands over her mouth. I looked back to see Madam Katarina naked. She was drawing on a harness with a thick, purple phallus thrusting from it. A dildo.
My eyes bulged at the sight of the strap-on. That was something that lesbians used. I shuddered there in place. Ingrid shook her head. She took a step back, but Madam Katarina’s voice cracked out like the riding crop.
“STOP!”
My twin sister froze in place. Madam Katarina shook her head and said, “En pointe.”
My sister rose onto her tiptoes, whimpering. She held the pose, her legs straight, her boobs quivering. I shuddered as Madam Katarina rubbed lube onto the dildo. She squeezed it from a bottle, coating the shaft in the glistening oil. Her naked tits rose and fell. They were so obscene on her slender frame.
The Russian woman grinned and bent down. She pulled something else out of her gym bag. A cone. She dumped the lube on that. I didn’t know what that was. She sauntered over to me, her breasts jiggling. I quivered there.
“Approach your sister, Ingrid,” commanded Madam Katarina. “Sigrid, bend over. Ingrid, put your right leg over your sister’s shoulder and stand on one foot. A modified grand battement.”
I bent over so my sister could do it. She looked so confused while I smelled something tart and wonderful. My twin sister’s pussy. I stared at her crotch. The pink leotard molded to her cuntlips. They sealed over it.
I hungered for her cunt. I wanted to feast on her.
“Madam Katarina?” whimpered my sister, her leg draped over my back. “What are you going to do to my sister?”
“Did I tell you to speak?” demanded Madam Katarina. She roughly yanked my leotard out of my butt-crack and to the side, exposing my pussy and butthole. “No. You will be silent. Do you want to be a swan or a sow that dances for men around a pole?”
“A swan,” my sister whimpered. “But ... but...”
“SILENCE!”
Madam Katarina’s voice echoed through the room. I shuddered at those words as she pressed something between my butt-crack. At first, I thought it was her dildo until that smacked me in the inner thigh. It was the cone.
She pushed the tip of the lubed cone right against my asshole. My eyes widened. I stared at my sister’s cameltoe, her crotch growing wetter and wetter by the moment. The cone drilled against my backdoor, pushing into me.
“Madam Katarina,” I whimpered as she stretched my asshole out more and more. It burned, this heat melting down to my cunt.
