The fifteen year old Billy was much smaller than his sister and was helpless to resist her and her sadistic boyfriend, Eric. "It is for us," laughed Eric as he watched his girlfriend bind her little brother. "I'm gonna get you for this!" he cried as he struggled effortlessly against the restraints. Amanda said nothing as she finished tying his hands tightly behind his back. She then walked in front of her brother and swept her hand across his face. Billy squealed in pain from the slap. "Shut the fuck up!" she demanded. "We're just getting started!" Tears were flowing down Billy's face. "With what?" he cried. Amanda smiled evily at her prize. "The dimwit parents left you with me all summer, Billy." she said. "We're going to have a lot of fun with you!" Billy struggled unsuccessfully against the restraints. "You can't do this to me! I'll tell mom!" "Your mom's gonna find out anyway, little man." laughed Eric. "Especially after Mandy here is done with you." Fear filled Billy's watery eyes. "What are you going to do to me?" Mandy smiled at her little brother and reached down to grab his cock. "We're going to make a few changes." she laughed. "No!" Billy screamed. Mandy smacked him across the face once again. "Stop your yelling or it will be more painful than I already have planned!" she demanded. "Please Mandy," sobbed Billy. "Please let me go." "We will eventually," she replied. "First we're going to make a few changes." "We need a name." interrupted Eric. Billy's eyes widened. "A name for who?" "For you, idiot." replied Mandy. "Now let's see, how about Susan or Sarah?" "Too generic," responded Eric. "Those are girls names!" cried Billy. "You can't do this to me!" Mandy slapped her younger brother again. "How about Brenda? It has a sexy sound to it. It should be perfect for our new little slut here." Eric smiled at his girlfriend, "I like it. Brenda she is." Billy continued to sob uncontrollably. Mandy placed her hand on his chin and gazed into his bloodshot eyes. "Now listen, Brenda. You best stop your crying before I start hurting you." "That's not my name," replied Billy. "I'm Billy! I'm a boy!" "Not anymore," laughed Mandy. "You are Brenda. You are my little fucktoy." Billy could not believe what was happening to him. His big sister whom he had looked to for protection all of his life was now turning him into a girl! He wanted to badly to run for the doorway, but knew he could never escape with his hands tied behind his back. Mandy landed another blow to Brenda's soaked face. "Answer me that you understand, bitch!" Billy tried desperately to hold in his sobs and swallowed what little pride he had left. "I understand, sis." Mandy smiled and kissed Brenda on her lips. "Good girl." Brenda stood naked and silent with her hands still bound behind her back as Mandy browsed through the seemingly endless selection of feminine underwear that she had. She wanted her new little sister to look perfect on her first day of training. She knew it was going to be very difficult for Brenda to get used to her new status as the house slut, so she wanted to make sure that everything was perfect. "Please don't do this to me!" pleaded Brenda. "I'll do anything you want me to!" Mandy laughed as she continued to browse. "I know you will, sweetie. Just relax." Brenda continued to sob as she awaited her new wardrobe. "It will take a while for you to get used to wearing female clothing," explained Mandy. "Soon I'll start you on estrogen and you won't think twice about it. You'll be so desperate to be a woman you won't be able to stand it!" She smiled as she pulled out a red lace thong and matching laced bra. "These should be perfect for your training." She turned to approach her new little sister when she noticed that Brenda's tiny cock was standing proud and erect as she cried. Mandy took her hand and gently wrapped it around the member. "You won't be needing this anymore," she whispered. "We'll take care of that soon enough." "Please, let me go." moaned Brenda. "I won't tell anyone, sis! I promise!" Without saying a word Mandy placed Brenda into the lace thong and bra set. She looked like the perfect little whore standing in the center of the room in nothing but laced underwear. Mandy dashed into the bathroom and soon came out carrying two flesh colored water balloons. "You don't have real breasts yet," she explained. "That will change as well, but until then you can use these." They were large for such a young girl like Brenda, but Mandy was extremely pleased with them. "A fifteen year old slut with a D cup." laughed Mandy. "You are the perfect slut! Once we get you on estrogen you should develop real ones that we can play with and show off to the world!" Brenda could do nothing but watch in horror at what was happening to her. Mandy topped off Brenda's new underwear with a matching red laced hose and garter set. "Red is your color, Brenda!" she laughed evily as she dug through the closet to find clothes for her new toy. She soon emerged carrying a red silk shirt and a small black skirt that would easily ride above Brenda's knees. Once her toy was dressed Mandy took a moment to step back and admire her artwork. The silk shirt was perfectly designed to curve down below Brenda's new breasts and gave her a dynamite figure. The skirt was beautiful and flowing and contrasted wonderfully with the red panty hose that Brenda was wearing. "You make a very attractive girl, Brenda. I almost want to fuck you myself!" laughed Mandy as she gently ran her hand over Brenda's body. Brenda continued to sob silently as her torture continued. The body form she was now staring at in the mirror was not the young Billy that she had been only an hour earlier. She was truly staring at the body of a slutty fifteen year old girl. Only her face bore the resemblance to that of a young man. She knew in her heart that it was only a short time before that changed as well. "Makeup time, slut!" exclaimed Mandy. Her voice was filled with excitement over what she was doing. She felt as though it were not only her little brother that she was getting revenge on, but all of the girls who had done her wrong in her life. She had complete control over this girl's life and she intended to make it a living hell! Brenda set quietly in a chair facing her sister's night stand. Dressed in her red silk blouse and black skirt she was truly a beautiful young lady. Only her hair and facial appearance were now lacking the beauty to match her body. Mandy began by placing a straight, blonde wig on her new sister. "A blonde!" laughed Mandy. "The ultimate bimbo slut. No need to think! Just to suck cock and get fucked!" Brenda watched in horror as the young boy she had been staring at in the mirror quickly vanished into the face of a beautiful fifteen year old blonde. Mandy was careful to apply eyeliner, blush, and other cosmetics to her face to ensure that she was a very intriuging piece of eye candy. Once she had finished with the makeup, Mandy leaned down beside her sister and smiled. "What do you think?" Brenda held back her tears as hard as she could. "I'm a girl." "You are!" laughed Mandy. "You're quite the hot piece of ass. I could make a fortune whoring you off! We're not done getting you ready, yet!" Mandy leaned over and picked up a tube of red lipstick from her dresser. "This is very cheap red lipstick, slut. It should come off on anything you kiss, eat or suck on." she giggled as she generously applied the lipstick to Brenda's mouth. "Don't worry too much about wiping it off tonight." she laughed. "It should all come off on its own after we're done with you!" She placed the tube of lipstick back on the counter and picked up another tube of makeup. "Some lip gloss to make those lips inviting!" she laughed. "We want you to be as desirable as possible for your first date!" Brenda gulped, "A date?" she asked. "Why yes!" replied Mandy. "We have to see you in action! I'm not going to dress you up like this unless I intend to use you!" "What are you going to do with me?" asked Brenda. The fear could be felt in her soft voice. "Whatever I want to!" whispered Mandy. "Maybe I'll invite all of my girlfriends over to watch you parade around for us! Maybe I'll invite all of my guy friends over and you can give them blowjobs until I am satisfied with your performance! Just think about that! You should be ready to do anything I tell you! If you do not, there will be serious consequences for you!" She resealed the lip gloss and placed in back on the dresser. They both took a moment to admire the sexy blonde in the mirror. Because of Billy/Brenda's young age he had very little hair and had a very thin figure. He truly looked like a sexy young blonde with a knockout body. "What a beautiful slut." said Mandy. "Now it's time to earn that title..."brenda1
