After they arrived home Jamie was pulled out of the car by her mom and led by her leash upstairs to their flat. Her mom removed the leash and handcuffs from Jamie's wrists and smacked her ass. "Make some baked salmon for two with asparagus and salads," her mom ordered, "Set the table for two with wine glasses."
"Yes Mistress," Jamie replied hearing her tummy rumbling since she had only eaten cum all day.
"You are not permitted to eat any of it," her Mistress ordered, "I have a date coming over tonight and if there is any left over you can eat it when you are cleaning dishes."
"Yes Mistress," Jamie said pouting.
Fortunately for Jamie her mom turned off the vibrator in her chastity belt so she could focus on preparing the meal. As she was working in the kitchen she was getting more and more hungry. She was about to sneak a bite of asparagus when she glanced up to see a camera watching over the kitchen. Her mom must have had it installed when she was being fitted with the chastity belt. Jamie knew she was already in big trouble so she continued cooking without sampling anything.
When her mom came in she was wearing an almost sheer black silk robe. "It smells delicious," her mom said as she came in and sampled an asparagus.
Brandi kissed Jamie on the back of her neck and said, "You will serve our meals and wine. When we don't need anything from you, you will kneel beside me with your head down. Is that understood my sweet little slave?"
"Yes Mistress," Jamie moaned as her mother kissed her neck.
At that moment the buzzer rang. "Go answer the door, slave," her mother said with a strong emphasis on the final word to prevent any rebellion from her daughter.
Jamie walked downstairs wearing just her collar and chastity belt. Nervously she opened the door to garage and was shocked to see her mom's sister.
"Aunt Brenda!" Jamie exclaimed.
Her aunt took Jamie into her arms and hugged her tightly. As they hugged she also caressed Jamie's exposed ass. "I am so happy to see your mom found a slave to abuse," Brenda said still caressing Jamie's ass, "now she won't need me to help satisfy her sadistic needs."
"You and mom?" Jamie said in shocked voice.
"Your mom and I have been lovers since we were kids," her aunt casually said, "but she used me once in a while as her pain bitch. I know it really turned her on so I didn't mind doing it on rare occasions. So I am so glad that I won't have to do that any more and the two of us can just be lovers."
Her aunt patted Jamie's chastity belt and continued, "I know it will be very rough on you but just know that it really turns on your mom."
As the two walked upstairs together, Brenda added, "Since you slept with your mom and agreed to be her slave, we thought it was time to be open with our relationship around you."
At that moment they reached the top of the stairs and were greeted by Jamie's mom. Instantly Jamie dropped to her knees as the two sisters embraced and began kissing each other passionately.
Jamie glanced up to see her aunt in the bright light of the great room. Her Aunt Brenda was about the same height as her mom. Whereas Brandi had a skinny body with soft round milf boobs, Brenda had a very skinny and trim body with a flat chest very similar to Jamie. Brenda also had long blonde hair pulled into a ponytail like Jamie and Brandi kept her bright blonde hair cut short.
The two women continued kissing passionately in front of Jamie, until they finally pulled away from each other. Brandi helped Brenda take off her trench coat to reveal that Brenda was only wearing a white garter belt and stockings with white high-heeled pumps and no bra. "My sister the slut," Brandi giggled as the two older women held their arms around each other's waist. "Look who is talking," Brenda laughed and she caressed Brandi's exposed nipples though the sheer material of her robe.
Brandi dropped Brenda's coat on top of Jamie and said, "hang that up then pour our wine.'
"Yes Mistress," Jamie said as she scrambled to get up and hang up the trench coat.
The two sisters relaxed on the couch kissing and fondling each other as Jamie placed the full glasses on a nearby table and knelt beside them.
Jamie glanced up at the two and saw their hands gliding over each other's bodies and longed to do the same. She also wanted to desperately rub her clit but knew that was impossible, so the teenager just waited impatiently on her knees.
