Derek sat anxiously in the waiting room of the plastic surgery center, his heart racing with anticipation. Today was the day he had been waiting for - the day he could finally get back at his bully, Mark, who had tormented him for years. Derek had planned and executed the perfect revenge, using his skills in hypnosis to make Mark believe he had always wanted to be a girl and that getting breast implants was his ultimate dream. As he sat there, pretending to flip through a magazine, Derek couldn't help but feel a twinge of satisfaction at the thought of Mark sitting next to him, completely oblivious to his true intentions. Just then, the door swung open and in walked Mark, looking excited and a bit nervous. "Hey Derek, I can't believe I'm finally doing this!" Mark exclaimed as he plopped down next to him, eagerly showing off a padded bra that he had brought with him to demonstrate how big his new boobs were going to be. Derek smirked inwardly, knowing that Mark had no idea what was really happening. "That's awesome, man. I'm happy for you," Derek replied, keeping up his facade of support. After what felt like an eternity, Mark's name was called and he jumped up eagerly, waving goodbye to Derek as he disappeared behind the double doors. Derek waited patiently, his heart pounding in anticipation of what was to come. Finally, the doors swung open once again and there stood Mark, with a big smile on his face and his hands cupping his newly acquired breasts. "Check it out, Derek! Aren't they amazing?" Mark gushed, practically bouncing with excitement. Derek couldn't help but chuckle at the sight before him. "They look great, man. But you know what would complete the look? A matching ass," he said with a sly grin. Mark's eyes widened with excitement. "Really? I can do that too?" he asked eagerly, already envisioning his new, curvier figure. Derek nodded, a sense of satisfaction washing over him. "Yep, your appointment is tomorrow. Get ready to have the full package," he said, relishing in the moment. Mark threw his arms around Derek in a tight hug, overcome with gratitude. "Thank you, Derek. I can't believe you're helping me achieve my dream," he said sincerely. Derek hugged him back, a devious smile playing on his lips. "Anything for a friend," he replied, knowing that his revenge on Mark was far from over. And as they sat in the waiting room, Derek felt no guilt or regret for what he had done. In fact, he couldn't wait to see the look on Mark's face when he woke up with a brand new behind. The tables had finally turned, and Derek was the one in control. He was the one calling the shots, and he was loving every minute of it. Revenge had never felt so sweet.
