Jenny and Tammy had been splitting all the household chores between them, including the cooking; Jenny was already a pretty good chef, and this evening she outdid herself, as she was preparing a very tasty meal.
Tammy came home from school at about 4:30, and her eyes bulged out a bit at the sight of Jenny, completely nude except for her collar and jewelry. "Wow. What happened, Jen? What'd Daddy do?"
"I am Da... Sir's slave now, young mistress" Jenny said, addressing Sir’s daughter the way Sir had instructed her while her eyes shined with pride in her role. "Dinner will be ready soon." She sniffed the air, and smiled slightly at the dried sperm still on young mistress’s cheek. "You might want to wash your face, young mistress."
Tammy shrugged. "How else am I s'posed to get an A in math?" she muttered, as she wandered upstairs to clean up.
An hour later, Jenny called Sir and his daughter to dinner.
"Slut, why are there three places set?" her father demanded.
"Uh... Da.. Sir, I... uh..."
He sighed, and pressed his lips together. "You may eat our leftovers while you're cleaning the kitchen after the meal. Slaves do not dine at the master’s unless they are invited, is that clear?"
"Yes, Sir," Jenny answered, and removed one of the place settings. She glared slightly at Tammy's giggle.
"Ah, this does smell delicious," Sir said as he sat at the table, with Tammy taking the seat next to him. "But I do need some attention while I eat."
"Attention, Sir?" Jenny asked.
Her dad undid his zipper and patted his knee. "Get under the table, slut."
Jenny crawled underneath, and began to suck Sir's cock while he and his daughter dined.
"Wow," Tammy whispered after looking at her under the table. "So this is how it's gonna be, huh Daddy? Pretty awesome for you."
"Mmmmm," he answered. "Yes. it's always the best to have a good slave girl in the house. Why, Pumpkin? Are you planning on following your sister's footsteps?"
