"Now that you've actually become my type, my lovely little love-slave, time for you to begin your half of the arrangement," Beel said gleefully. Marcia held up her hands, which jingled from her many bangles.
"Um, just give me a second, I need some time to get used to this," she said urgently. Beel laughed.
"As if! Lovely little Marcia, if you want to be male again, you're going to have sex with me whenever I say, however I say," he said. Marcia swallowed. She lowered her head.
"All right." She braced herself. Beel grabbed Marcia and took her further up the tower, up to his bedroom. It was full of magical relics that Marcia was forbidden from even getting close to when she cleaned. In the middle of the room was Beel's bed, a massive four-poster covered in feather pillows, silk sheets, and cashmere blankets. Beel led her immediately to the bed. "I'll get un-" Before Marcia could finish her sentence, Beel snapped his fingers. Her clothes disappeared, leaving her completely naked.
"Time to break you in, love-slave," Beel purred. He threw Marcia onto the bed. Marcia sighed, enjoying the feel of the luxurious bedding on her naked body. Then Beel climbed on, nude as well. He lowered his head to Marcia's, pulling her into a deep kiss. Despite herself, Marcia found herself returning the kiss, even initiating tongue action. While she was distracted by the kiss, Beel plunged his cock deep into her pussy. Marcia let out a moan, her eyes wide.
Beel thrust into Marcia, over and over, making her cry out and squeal like a porn star. He made eye contact with her the entire time, ensuring she kept in mind the person who had complete control over her now. Finally, he came, filling her empty womb with his seed. Beel pulled out of her, smiling smugly.
"Good work, my lovely lovely Marcia," he cooed. He climbed off her. His face went serious. "Now, get dressed and get back to work."
Marcia hurried down from the bed. She pulled on the thin silks that now comprised her clothes and ran back to the kitchen to make Beel his dinner. Her newly massive bust and butt bouncing the entire way.
