Marge's eyes popped wide open as she stared at her daughter. Lisa was pretty confident that her mother would let her get fucked by Homer now that she caught her with Bart's cum still dribbling from her used cunt, but what she assumed was simply surprise in Marge's eyes was not. The blue haired milf couldn't believe her little daughter could hope to blackmail her!
"If your father wants to fuck you, well that's his business! But you, young lady, need a good punishment for trying to blackmail your mother and your big brother!"
On those words, Marge lunged at Lisa, grabbed her by the arm and dragged her in the living room. Bart dumbly followed the pair, still naked, curious to see his naked mother punish his annoying little snob of a sister.
Once downstairs, Marge threw Lisa on the couch and sat down beside her. She then forced her daughter to lie down across her legs, on her tummy, ass pointing to the large bay window. Lisa was struggling against her mother, so Marge had her work cut out for her just holding down Lisa.
"Bart help me with your little sister!"
Bart nodded, eager to participate in the degradation of his sister.
"Flip her dress over her ass and take off her panties."
Lisa kicked and screamed her protest, but Bart nevertheless did as instructed. He even went to the extra effort of pulling his sister's dress up over her head and off of her altogether, leaving her naked too. He then grabbed hold of her wrists so Marge could be free to do as she wanted.
"Thank you, Bart."
On these words Marge immediately began spanking her daughter as hard as she could. Lisa's little wiggling ass quickly turned red and then purple.
"That'll teach you to try to blackmail people! Never, ever, try that again!"
The spanking noises, unbelievably erotic view of Marge's large tits swaying from side to side each time her hand fell down on Lisa's small ass and the sight of his sister's small naked body trembling from her punishment was more then enough to get Bart hard again and even dripping pre-cum. Little did he know that Lisa was getting incredibly aroused too. She didn't fully understand it herself, but that treatment was arousing her more than she could have believed. The way they were positioned Lisa's face was only inches from her brother's surprisingly large member, and her hands were in reach since Bart had shifted slightly on the couch. |
