Max's Mom...

Britney had decided to check up on her son after he had excused himself from the table. Yes, he was pounding her slut of a sister on the regular, but that doesn't mean he had to leave everyone else alone. She had needs too damn it and she was going to get some too. She silently admitted to herself that seeing Alison knocked up again made her feel bit jealous, she had loved being pregnant and what it had done to her figure.

Looking down past her light brown hair to her own impressive figure. Although not as busty as her sister (especially now that she's knocked up by her studly little son), she knew she had some nice big tits that had grown from each pregnancy from a nice B cup to at a healthy D cup. She kept nice and thin with regular yoga sessions, and had some ridiculous 'child bearing' hips that had driven her husband wild (while he was around anyways.)

She took a quick pit stop in the bathroom to make sure she wasn't showing any obvious signs she was lusting after her son's thick cock, and heard someone head into Alison's room... Shit...

Britney slowly opened the bathroom door and approached the bedroom door, already open a crack. That slut sister of her's already had Max behind her pounding away and giving her a triumphant look while she got pounded. As the show went on, she drank in the scene of her son's long, thick cock plunging into her sister's hungry pregnant pussy, heavy balls churning with another thick load to pump into her sexy slut sister. Britney bit her lower lip and started to cup her breasts as she flushed with arousal at the scene.

As Max continued to fuck the ever-loving hell out of his aunt, his mother began to finger herself in the hallway, plunging her fingers up her pussy as she watched and listened to her slutty sister take every inch of him. She felt herself starting to get to the edge as they were, but her sister's words threw her over the edge.

"Oooooh, you're gonna cum, aren't you? Gonna pump your knocked up slut's pussy full of cum? Gonna bathe your own daughter in the incestuous sperm that made her? God FUCKING DAMN! Cum in this pussy! Pump me full of your cum you pussy destroying STUD!"

Her world went white as she came, having to grab the door to steady herself as she imagined herself like her sister, knocked up with her stud son's fat cock in her pregnant pussy, drenching his own little girl in the womb he had been born out of and was claiming as his own. His own little incestuous baby factory... just like her sister...

She glanced up as the world came back around her, into the bedroom. They had just finished, laying across from one another while they caught their breaths. Her son's glorious, slut-taming cock was still hard, pointing up into the air, not flagging in the slightest. His balls still somehow looking packed full of cum, even though she could see a torrent of his seed dripping down her sister's thigh... It wasn't right... it was her cock... her baby's cock... it was supposed to be her's...
