It was finally the end of the school year. Breanna and Paige were on their way home to their mother's, and both girls were over the moon with excitement. The train ride from the academy was about an hour long, and the girls could barely contain themselves as they looked forward to the possibilities the coming months living with their mother could bring.
Each girl had one thing on their mind, and that was fulfilling their long held fantasy of a threesome with each other and their mom. Since Paige's first encounter with Lilian, she had kept her promise and hadn't revealed a thing to her sister. Likewise, Bree never told Paige about her own sexual trysts with the woman who'd raised them.
The older of the sisters had been struggling for a long time with her secret. She knew she wanted to share it with Paige, but sneaking around with their mom had been so exciting! Now that they were arriving home at last, though, she knew she had to come clean. Bree bit her lip nervously and turned to look at her sister.
"Paige," she began. "I have a confession to make."
Paige smiled. She knew exactly what Bree was going to say. 'Finally!' she thought to herself. "You mean about you and Mom?" she said aloud.
Bree balked. "Um... y-yes..."
Paige reached over to her sister and put her hand on the girl's thigh. "It's alright, Sis. I know you've been fucking her. I'm not mad."
Once she was over the shock, relief appeared on Bree's face. "Paige, I..."
"I have a confession, too." Paige continued, interrupting her sister. "I've sort of been... having sex with Mom, too."
Bree's jaw fell open. She was speechless. She sat back in her seat, and a wide grin spread across her face. "You little slut!" she said with a laugh. "How long has it been?"
"Almost a month. She visits me once or twice a week."
"Me too. We first started the night she told us she left Daddy..."
The girls sat quietly, smiling mischievously at one another. "So... what do we do now?" Bree finally asked.
Paige giggled, and took her sister's hand in her own. "We fuck her together, obviously!" The girls both burst with laughter, each suddenly very eager to get home as quickly as possible.
----------------------------------
The girls took a cab home from the train station, expecting their mother would still be at work when they arrived. It was late evening, but Lilian had a habit of working long hours. When they got out of the car, they looked up at the large home they'd grown up in for the first time in almost a year.
"Home sweet home." Bree said with a grin. Paige giggled, and raced up the driveway, followed quickly by her older sister.
"Welcome home girls!" The two young women were surprised to be greeted by their mom as they walked into the kitchen.
"Oh! Mom! Um... We thought you'd still be working!" Paige replied. She found herself more than a little distracted by her mother's attire. The older woman was dressed in a very short, very form fitting lace nightgown.
She walked up to her younger daughter and gave her a loving hug. "Don't be silly, Paige. Of course I wanted to be home when you girls arrived. Have you eaten?" Lilian asked.
"Err, yes. We had something on the train." Bree replied. Her eyes were glued to the older woman's ample cleavage.
"Good. Well, you must be tired from your trip. I've laid out some fresh outfits in your room. Why don't you go and get changed, and I'll get a little snack together for you."
"Um... alright." the girls answered simultaneously. They went upstairs to their shared bedroom. On their beds, they found a pair of faded looking nightshirts.
"Oh my God! Paige, do you remember these?" Bree exclaimed. She held hers up. It was a faded pink colour, with an image of the powerpuff girls on the front, piled together in a group hug with each other.
"Holy shit! These are from when we were little kids!" Paige said with a laugh. Her's was powder blue, with a picture of the little mermaid smiling up at her on the front. "Do you think they'll even fit?"
Bree shrugged. "Let's find out!"
When they were younger, they used the shirts as nighties. At the time they hung down past their knees. As adults, however, the shirts barely stretched over their supple bodies, and the hems ended midway over their asses.
"Damn, you look hot in that!" Paige exclaimed, eyeing her big sister with growing excitement.
"You don't look so bad yourself, Sis." Bree replied, raking her eyes over the younger girl's curves. She giggled, walking over to the nightstand. She dug around in one of the drawers, finding a pair of hair elastics.
"If Mom wants us to dress like we did when we were younger, we might as well go all out!" she said. She looked in the mirror and tied her hair up in pigtails. The effect made her look several years younger than she was.
"Hahaha! Nice idea, Bree!" Paige cried. She joined her sister by the mirror and put her own hair up the same way.
"Girls! Are you almost changed? Your snack is ready in the living room!" Lilian called from downstairs.
