The day after classes started the same as any other. I began my walk home with three of my closest friends, Amy, Kristen and Rachel. We were in our third week of high school. Amy was sixteen and a sophomore. She had hazel eyes, long blonde hair and the body of a super model. Kristen was sixteen as well, twin sister of Amy, and also had blonde hair and hazel eyes. Both were identical in just about every way. Kristen was the oldest, a senior and just shy of her eighteenth birthday. She had brown hair and green eyes and was very attractive.

My name is Karen. I am fifteen and have brown eyes and hair. As we walked home, the main topic of course was the boys in school. We gossiped and laughed listening to one another and how many guys had hit on each of us since we began the year. The crisp air of fall was all around us and winter was approaching fast. Already the leaves had begun showing their brilliant shades of yellow, red, brown and orange. The path we walked was wooded on either side with a creek flowing on the left side of the path. The four if us had walked it dozens of times each way to school and knew it well. Usually we walked it alone without much activity. But this time while we were talking we did not notice the approach of three strangers. We rounded a bend in the path and came across them. All three were girls that looked perfectly harmless and nothing to be frightened of.

"Hello," Kristen said to them as we approached. Her greeting was met with silence and we started to get closer to them. Amy noticed it first. Their eyes seemed to be vacant and unblinking. Then the eyes began to glow and look at us. Amy tried to scream as beams shot from the girl's eyes stopping her in her tracks. Kristen and Rachel met a similar fate as I did. We stood frozen in our tracks scared and helpless as they came closer.

"Resistance is futile. Undress now and kneel," one of the girls said her voice almost robotic in tone. Amy began uncontrollably removing her shirt and pants. The rest of us soon followed as though we were in a trance. We were conscious but totally unable to control ourselves. We stood there nude and shivering on the path powerless to cover our naked bodies. We tried to scream for help but all that was mustered were muffled cries because we could not open our mouths. Then the girls undressed. Each wore a steel collar and wrist and ankle bracelets and their nipples, clits and labia's were pierced. Their breasts were huge and droplets of milk began to run down their fronts and all trace of body hair below the neck was non-existent. Our eyes went wide seeing them.

One of the girls approached Kristen first as she removed a collar from a bag. Kristen whimpered as she saw there was no lock on the collar. The girl placed it around her neck and with a loud click it locked in place. Amy was next and began to cry. The girl caressed her breasts and said, "soon you will be like us" in a robotic unemotional tone. Rachel was next to being collared followed by me. The cold steel collar encircled my neck and locked into place with a loud click. Wrist and ankle bracelets soon followed then our hands were secured in place behind our necks attached to the collar by a ring. We stood there helplessly praying for someone to come around the corner and help but no one came. The girls secured a gag in our mouths as we tearfully tried fighting then attached leashes to each of our collars. We began to walk down the path to a small crossing, our clothes and books carried by one of the girls leaving no trace we were on the path. As we rounded the corner, a van awaited. The girls placed us in it one at a time, still unable to move and laid us on our backs and spread our legs wide and elevated. Then the van began to drive off with us inside. I wondered what was going to happen to us and where we were being taken.

Two of the girls remained in the back with us, as we lay helpless and exposed and crying silently. I noticed a sweet smell in the van. I did not know where it was coming from until one of the girls moved beside me. The smell came from her sex and nipples as she caressed my naked body with a cool touch. The girl removed my gag as she caressed me and turned the heads of my friends to look at me. Speech was still impossible as I tried to scream, "let go of me! Why are you doing this to us? What do you want?" My silent pleas of protest were soon met with a muffled groan as the girl touched my sex. Then out of the corner of my eye, I watched as her fingers began to elongate and what looked like tentacles grew from her them. One began to enter my sex as I tried to scream another entered my anal opening, both penetrating deep. I felt a sharp pain as something was inserted into each of my openings and remained inside me. The other hand moved towards my breasts and penetrated the underside of my breasts, causing excruciating pain. I felt something entering each of my tender breasts and a sharp pain as something activated inside each. I gasped as my friends gazed in horror. Then I felt the tentacles being removed from my breasts as I gasped in shock and pain. Then Rachel let out a muffled scream as the girl did the same to her as I watched the tentacles enter her blonde sex and her tender breasts. Kristen was the last to be done, forced to watch as Amy met the same fate as her sister. What was happening to us? Who were these girls? Another question loomed in my mind. What or who was controlling them?

The van pulled into a driveway then disappeared into darkness. I knew we were in a garage or a tunnel. The side door opened and we were led still unable to control our movements into a small room. The gags were removed but our hands remained cuffed as we were allowed to finally move. The twins began to cry frantically as we were locked into the room. Only a television screen and two small mats were in the room and there were no windows. My sex and breasts burned from the intrusion that we had endured.

"What the hell is happing to us?" Kristen asked.

"I don't know," Replied Rachel. "But it can't be good."

"My breasts feel funny," Amy said tearfully.

"So do mine," I replied. "What did they put in us?"

"Some sort of probes," Kristen suggested. "What did she put in my ass and vagina? What are they doing to us?"

The question was answered as the television turned on and a man appeared on the screen.

"Good evening slaves," he began. "My name is Devin. But in a few days you will be calling me Master. By now you are wondering what has been done to you and the three girls who you met. You will find out soon. Your enslavement has already begun. By now you already feel your breasts growing. Don't be frightened. The implants merely enlarge the breasts and make you produce hypnotic milk. The implants in your ass and vaginas control your sexual desires forever. The smell you noticed is pheromones that in time will entice others to become slaves. You are to become like the others, mindless robotic sex slaves. Resistance is futile. Let me demonstrate."

A button was pushed on a control pad and Kristen began screaming and writhing in pain. She collapsed on the floor still screaming as her body tensed.

"Make it stop!" Kristen screamed. "Oh God, make it stop! AAAAAHHH! Make it stop!" The button was released and she gasped and screamed.

"The implants I forgot to mention produce intense shocks if you disobey," Devin said with a sinister smile. Then another button was pressed and with a gasp from each of us, the implants vibrated for a moment before stopping. "The implants are programmed to emit shocks if you try to resist automatically. There is no escape. There also is no way to remove them. Any attempt to do so would be fatal. Tomorrow after your breasts have grown, you will continue the process. And oh yes. The only food provided you produce."

The monitor was turned off leaving us in shock and disbelief. Kristen was stunned still lying on the floor still feeling the burning after effects of the demonstration.

"What did he mean by we will soon call him Master?" I said.

"And what did he mean by the only food we produce?" Amy said, crying.

"I think it means we are to drink from each other." Rachel said with a terrified look.

"I would rather die first before that happens," Amy said. "I don't want to become a slave."

"Then it's settled," Kristen said still gasping. "We will not drink the milk from one another."

"My body itches all over," Rachel said gasping and writhing.

"So does mine," Amy replied. "It feels like my hair is standing on end."

I began writhing as well. There were no blankets so we huddled together as best we could on the floor. None of us could sleep as we lay there feeling our breasts being enlarged. Rachel noticed it first late in the night. With a gasp she looked at her sex and noticed the hair began falling out. She began crying and by morning, we were bald from the neck down and feeling very exposed. Kristen noticed droplets of milk trickle down her chest and began smelling the pheromones starting to kick in. By morning all of us were in the same state of arousal. Amy lost control first then Rachel and Kristen and I watched as the two began devouring each other's sexes.

"I'm hungry," Rachel said, gasping and moaning in pleasure from her sister. Kristen had moved close to me and had just begun to devour my sex.

"Don't drink you can't," I said. But it was too late. Amy moved up close to Rachel's mouth, her breasts now very large. Rachel opened her mouth as her sister presented her breasts inviting her to suck. She began to as Amy moaned. Rachel moaned as well as the milk began to affect her. In a few moments, her eyes became fixed and glazed as she sucked greedily. Kristen had moved between my legs once more and was devouring me against my will. I gasped and pleaded but it was no use. The pheromones had taken total control of her and she was deep in lust. She moved to my breast and before I could stop her she began to suck. With my hands still cuffed behind my neck there was no chance of pushing her off. I lay there crying as I watched her eyes glaze over. Amy had moved to Rachel's nipple with her mouth and had begun to drink as well. Rachel lay on her back motionless her eyes open and glazed over. Kristen moved beside me bringing her breasts close to my mouth. The pheromones began to overpower me as I tried to resist. Then without realizing it, I opened my mouth and began to drink. The last thing I remembered before going under was a voice laughing over the intercom.

I awoke some time later, and my head was spinning from the milk and pheromones. I was awake but gagged, standing nude and spread-eagle in special cuffs. I was so hungry and I knew I had not been allowed to eat until the milk had worn off. As I came too fully, I looked around the room. There beside me, Amy stood spread-eagled and gagged, looking fearfully at me, crying trying to wriggle out of her cuffs. It was no use. The cuffs held fast as we awaited our fate. Both of us were writhing in the cuffs crazed with the pheromones we were emitting wanting to feed from one another. But where were Kristen and Rachel?

The question was soon answered as Rachel was led into the room by a leash, her hands cuffed behind her back. Two males led her in and brought her to a special mat. There her hands were uncuffed as she was placed on her hands and knees. The cuffs were fastened to metal rings to her wrists and ankles keeping her from rising. She saw us and began to cry.

"Help me! I was forced to watch Rachel have this done! Please oh God no!" was all she could say before a male knelt and inserted his sex into her mouth as she tried to scream. The other male moved behind her on his knees and penetrated her helpless sex. As he began to thrust deep into her, the screams began to turn into moans and she began sucking off the male's sex. Her eyes began to glaze and I realized the males held the same power with their semen as our milk did. She sucked greedily as she was fed the semen. Then with a muffled scream, the male moved her hair away from her temples and the fingers elongated. We watched helplessly as the tentacles penetrated her mind and embedded the probes. As they activated her pupils disappeared as the male smiled. Kristen was then let out of the cuffs and led to a special table. As she lay motionless a large laser moved from the ceiling then targeted her mind. What was it doing to her? The answer became clear as a screen appeared showing her naked body. Small bits of metal began to appear inside her as she began to be transformed. Where bone showed, the metal replaced it. The rest of her body on the inside soon followed, as blood vessels became clear tubes full of fluid to allow movement. Her mind became a small CPU controlling her robotic body. All trace of organs were removed and replaced with circuits and wires. Her skin was left alone, keeping the allusion of a normal human body. The breasts enlarged further as the probes became large sensors inside, allowing her to feel pleasure but not pain.

The work was done as we watched helplessly, knowing we would be next. Kristen was finally allowed off the table and moved over beside us.

"Don't be frightened, it is rather fun being made into a robot," she said with a grin. She moved over to Amy and caressed her, then as Amy screamed through her gag Kristen pressed a button and the laser moved over in front of her. She screamed even louder as Kristen moved behind her then moved her hair away from her temples. As I watched, Kristen, our best friend embedded the probes in her mind. Then Kristen activated the laser aimed at Amy's forehead, as I stood helpless and screaming. I was to be done last, it seemed. My friends had become robots and I was totally powerless to stop it from happening to me.

Amy was done in a few hours and released from the cuffs. Blue eyes that had been so alight with love and flirting now were cool steel, unmoving. Kristen kissed Amy and the two embraced one another. Rachel was allowed out and came to their side. The three began to grope and fondle one another moaning in pleasure as I stood watching. Then the three looked at me and smiled.

"Your turn," they said together in a robotic tone. Then they approached and began to fondle me, as I lay helpless in the cuffs. "No please, let me alone," I wanted to scream, but part of me wanted to join my friends. We had grown up together. We could not be separated like this. The last memory I had was feeling the probes entering my mind then activating.

Six years have passed. We have not aged a day. We graduated high school together while living with Master. Our nights were passed making mindless robotic love to each other and then later on we began getting the chance to increase Master's robot production. The teachers we had turned into robots, along with many of our classmates. College we all enjoyed, as best robots could. I watched, as my roommate named Jennifer became a perfect robot. We were programmed to enslave any that smelled our pheromones or wanted us in bed. It was fun to actually turn jocks into robot pets. We would never age, not even a day. We were happy with the thought of that. Soon, Master sent us to other parts of the world, making sure others would be given the chance to enjoy our pleasure. We made love to thousands, our sexes nice and deep for males to take and ultra sensitive to female tongues.

Master sent me to your town. That's right, come play with me. Oh yes. Make love to me. Bring your friends. Let them experience your new girlfriend. Don't be frightened. The process only hurts for a few seconds. Don't you want me? That's rights, caress my breasts and begin to suck. You will love the taste. You will love becoming a robot.
