Taking what's her's.

Alison looked up into her sister's eyes and was actually startled. Britney wasn't in the hallway anymore, she was starting to walk towards her son, who seemed to still be too much in the afterglow to notice yet. The shock of her sister actually having the stones to actually come in was quickly followed by pure arousal. Britney was already mostly naked, her tits already bare from her shirt and bra being torn off and her skirt being yanked up to reveal her bare, dripping pussy. Her horny little sister had never let herself just let loose and take what she wanted, always the dutiful wife (except for the few times they had fooled around together, since that "family didn't count").

She had always been the sluttier of the two of them and relished in rubbing it in her sister's face, especially after she got knocked up since Britney had a huge pregnancy fetish. But now, her sister wasn't even looking at her like usual, eyeing her round belly and swollen tits with envy. Britney was now transfixed by her son's fat cock proudly waving in the air. Alison licked her lips, it had been awhile since she tasted her little sister's pussy when they went wild, and this looked like it was going to get REALLY fun.

Max started coming around as he heard footsteps behind him. He turned around to see his mother walking towards him. His first instinct was panic, and as he started grabbing for some sheets or a pillow, he felt a hand on his and some giggles behind his back. His mother had already gotten to him and he shut his eyes and prepared for the clusterfuck to begin, but instead of feeling a slap, the beginning of a tirade of 'how could he' or anything else he expected, he felt a warm, wet, velvety sensation envelop his cock that had started to flag as panic started taking blood elsewhere to deal with the new situation. Though, this new situation was pulling blood right back down into his cock with gusto as he felt this warm and wet sensation start to bob up and down on his cock.

Prying his eyes open he couldn't believe his eyes. His mom had wrapped her lips around his cock and was flat out worshiping his cock, giving the best blowjob he'd ever had. As his brain started to take in more information, he noticed her delicious tits were bare and already had her hand between her legs, fingering herself as she started deep-throating his cock. He also noticed a fit of giggles coming from next to him as Aunt Alison brought herself over him.

"I think my little sister is a little jealous and wants in on some of this, stud." Aunt Alison said as she reached down to cup Max's full balls.

Max's mind whirled as he tried to think about how this was happening. He didn't mind fucking his mom after Aunt Alison, they were both hot babes, but when did his mom apparently start craving his cock? Also, why is Aunt Alison so cool with this? He also felt like he just shot more cum into her then he had in his entire life, and he was already rock hard and raring to go?

Then he remembered what he put in the what if machine. He can "keep up with and satisfy any woman" and his mom would be included in "my family is fine with ****, especially with hot women towards me". While he hadn't planned on banging his mom, definitely his hot cousins first, he sure wasn't against it.

Calming down now that he knew he wasn't in trouble, Max let himself relax into the sensations from his mother's mouth wrapped around his cock. If he hadn't just tried to pump his Aunt up with enough cum to make her look like she was carrying triplets, he probably would have already given the lovely woman worshiping his cock a full load of her own to swallow.

Aunt Alison brought her lips to his ear, pressing her massive tits into his arm and whispered to Max, "Don't waste that delicious load down your mother's throat, I think this horny little slut's been jealous of me and I think you should pump a new little baby sister into her hungry little cunt." Punctuating her sentence with a nibble to his ear.

Looking down, past Aunt Alison, Max staring into his mother's eyes, he started wondering, what did he want to do with the luscious milf now between his legs? Feed her his cum? Fuck her delicious round ass? Maybe even like Aunt Alison said, and pump another little incestuous baby into his own mother's womb?
