After her initial visit, Lilian began to arrange more frequent meetings with her eldest daughter. Bree kept these visits a secret from Paige at her mother's insistence. Each time they got together, Lilian would start off by acting harshly with Bree, but they would always end up the same way- fingering each other's drooling cunts to a glorious, incestuous orgasm.
Bree found herself obsessing over her mother's pussy as much as she did her sister's, and it was driving her to exhaustion. Lilian would come to the school 2 or 3 times a week for their clandestine meetings, and Paige still insisted on fucking her sister for hours every night before they went to sleep.
The girls still fantasized regularly together about their mother. Bree desperately wanted to tell Paige about her and Lilian's affair, but she was still afraid of how her mom would react. Lilian still seemed uncomfortable with what they were doing, despite how much she obviously craved it, and Bree didn't want to do anything that would push her discomfort any further.
Bree also wondered if she should tell her mom about her and Paige, but decided against it almost immediately. It was obviously hard enough for Lilian to indulge in depraved activities with one daughter... Bree knew including her sister would drive their mom over the deep end.
"Hey, you wanna go hang out in our room this afternoon?" Paige asked her sister with a devilish wink.
It was Sunday, and they were in the library finishing up the last of their homework. Bree had been day dreaming, envisioning herself with both of her lovely family members, the three of them fucking in a glorious, incestuous pile.
"Hmm? Sorry, Sis, what did you say?" she asked, snapping back to reality.
"I'm done with this stupid english paper, and I'm horny! Let's go fuck!" Paige replied, slipping a hand over her sister's knee.
Bree groaned, her thighs spreading automatically. She looked at the clock on the wall and shook her head reluctantly.
"Sorry, Sis. I can't. I'm meeting a friend."
"Oh... Well, can I come with?"
Bree hesitated. "Um... You should probably just go back to the room and wait for me. I plan on using you as an excuse to leave sooner. That way we can get some fucking in before supper."
Paige grinned at her big sis. "I like the way you think!" She looked around, then leaned forward, kissing the older girl tenderly. The kiss left Bree's pussy creaming in her panties.
"Hurry up, though. My cunt's begging to feel your tongue..." the younger girl said sexily. She got up and left the library, swaying her hips seductively as she went.
Bree shook her head and stood too, preparing herself for another meeting with her sexually charged mother.
--------------------------------
"Hello, Dear. You're late again." Lilian said as Bree entered the visitor's unit.
"Sorry, Mom. Paige held me up." her daughter replied. She noticed her mom's face blush at the mention of her sister's name.
"Where did you tell her you were going?"
"Just to hang with a friend. Don't worry, she doesn't suspect anything." Bree walked up to her mother and grabbed her by the back of the head, devouring the older woman's mouth with her own. The two women kissed feverishly for several seconds before ripping their swollen lips apart again.
"You're such a fucking whore." Lilian muttered.
In response, Bree stepped back and started to strip herself naked. Lilian watched with hungry eyes as her daughter's body was slowly revealed. Once she was naked, Bree stepped forward again, and started undoing her mother's skirt.
"What excuse are you going to make up for yourself this time, Mom? That I'm forcing you to do this? Or that I tricked you? You know, if you didn't want this as badly as I did, you wouldn't be coming to see me like this."
Lilian pursed her lips, but didn't respond. She felt her skirt fall over her hips and puddle to the floor.
Bree grabbed her mother's sweater and pulled it up. "Why can't you just admit that you want this, Mom? That you want to fuck your daughter?" The sweater joined the skirt, followed quickly by her bra.
"Because I'm not a pervert." Lilian finally replied.
"Oh? You're not?" Bree shot back. She had her thumbs hooked inside her mom's panties. She pulled them down too, bending over to collect them before standing up again.
"Because you sure smell like one." Bree brought the soiled panties to her nose and breathed in deeply. Lilian quivered as she watched.
"I know you're going to argue with me, but I've decided I'm going to lick your pussy today, Mom. I'm going to lick it, and I know you want me to."
