Skyro: Thanks! There is always more to come as long as I have ideas!
megadeth425: I'm glad you like it so far! The early chapters of this are probably going to be relatively short, each exposing Lisa into something new in her relationship with Marge and Bart, but I will try to keep them longer and quality!

Her First Blowjob
Lisa was afraid to move. She wasn't sure how her mom and brother would react to her peeping in on them during such an intimate moment. She sat in silence for a few seconds, staring at the floor, unable to hear Marge and Bart if they were saying anything.
The next thing she felt was someone pulling her up to her feet. She looked up and was greeted by the naked body of her mother.
"Lisa," Marge said, "were you spying on me and your brother?"
Lisa looked her mom in the eyes, then hung her head in shame. Even though she was trying not to, she couldn't help but admire her mom's body. Even at her age, she continued to keep herself sexy and in shape. Her breasts were beautiful and small enough to not have been destroyed by time and gravity. Down below, she had a small, well-kept patch of blue hair above her privates.
"Yes..." Lisa replied, trying to break away from these thoughts of her mother, "I saw the whole thing."
"Good," said Marge, "that gets explanations out of the way!" With that, she pulled Lisa up to her level and gave her a kiss on the lips. Lisa was shocked but couldn't help but kiss back, fueled by the sexy sights from before. Lisa became lost in the moment and wrapped her arms and legs around Marge, rubbing her body against her. Marge, meanwhile, moved her hands down her daughter's back and up her night gown to her ass, giving it a good squeeze. Marge broke the kiss.
"What a nice ass my little girl has," she said, "and she's not a bad kisser, either!"
Lisa was eager to press her lips back to her mom's, but was interrupted while leaning in.
"Damn, mom! If I knew you and Lisa would be doing this infront of me, I would have gotten you two together long ago!"
Marge and Lisa took their attention off of eachother to look over at Bart, leaning against the headboard of his bed, stroking his thick dick.
"What do you say, Lisa? Do you want to sample the cock that made me sleep with my son behind Homer's back?"
Lisa nodded slowly, her eyes following Bart's hand as it pumped up and down his erection. Marge put Lisa back down to the floor, allowing her to remove her night gown, her only article of clothing.
Together, mother and daughter joined Bart on the bed and settled inbetween his legs. Bart let go and put his hands behind his head, allowing the ladies to examine his amazing meat.
"Wow..." Lisa gasped, "It looks even bigger up close!" She hesitantly moved a hand toward it, wrapping her fingers around as much of it as she could hold.
Marge joined in, bringing a hand to it as well, pumping slowly.
"Go on dear, move your hand like me."
Lisa complied and began to pump her fist. While she was distractred by the dick infront of her, Marge leaned in and began kissing her again.
"Aw fuck, you two!" said Bart, "If you keep doing that I may just blow my load all over you before you get to the good part!"
Marge broke away and smiled at her son. "Come on, Lisa, follow my lead." Still pumping with one hand, Marge leaned her head in down to Bart's balls and took his left in her mouth. Lisa, watching intently, leaned in and did the same to his right. The mother daughter team worked his balls in their mouths for a few seconds, then Marge removed it and pressed her tongue to the shaft, licking it up from the bottom to the top. Lisa followed her mother's example and soon the two were licking up and down Bart's cock in unison.
Marge brought her mouth to the tip, licked around the head, then took it into her mouth. She bobbed her head up and down, slowly taking more and more in while Lisa continued licking the sides of the shaft. Lisa then moved to the top with Marge as the two both began working the head over with their mouths and tongues.
"Fuck!" said Bart, "I'm gonna cum!"
Bart's semen pumped out in long streams, some going into Marge and Lisa's open mouths, but most of it landing on their faces. Bart's orgasm did not stop the two, however, as they continued to lick and suck at his cock, cleaning it, eventually moving to eachother's faces. Once again the two were lip-locked, swapping Bart's cum between eachother. When she pulled away, Marge swallowed and Lisa, not wanting to disappoint, did too.
"Bleh!" was Lisa's response to that.
"Don't worry, it's not for everyone," said Marge, "Next time we do that, just make sure you give it all to me."
"I'll remember that from now on... but what do we do now? Don't they go limp after that?"
"That's another reason I love Bart. His stamina!"
Lisa looked back to Bart and, sure enough, he was already starting to get hard again.
"So what do you say, Lisa," said Marge, "Are you ready to lose your virginity to your brother?"
Lisa nodded enthusiasticly. "You BET I am!"
Bart raised his hands in the air in triumph. "I have the best mom and sister in the WORLD!"
