Previously, after her son injures his arm, Lisa offers to help finish up Will's wax, only to learn first-hand why his wax session had been interrupted before. Having felt an intense shame at helping her son cum all over her, she navigates complex mixed feelings. Now, weeks later...

"Harder, harder, please, fuck me, c'mon baby, make Momma proud!"
"Oh yeah, take, uhm... take this big cock you... dirty little... uhm... ragamuffin you."
Lisa groaned internally, but redoubled her efforts, grinding her hips down furiously on her husband Steve. She was pleased that he seemed receptive to her efforts to spice up the bedroom and his eyes did light up at the sight of her wearing a corset and garters. She could even give him points for at least trying to get into the dirty-talk with her. But as she tried to ride a hole into the bed straddled atop him, she could admit some frustration as she gradually lost that sensation of fullness inside her. Dammit, she was so close!
Steve rolled her off him unceremoniously, gave her a pat on the ass, and walked to the bathroom. She couldn't blame him for her dissatisfaction, not entirely. In truth, it had probably been closer to months since they'd last made love, and recent... events... had ramped up her sex drive to unhealthy levels. She reached in her drawer, and grabbed woman's best friend. She slowly felt the disappointment fade away to the buzzing sound of her vibrator, hips bucking and gyrating to the hum as her latest fantasy rooted itself in her mind.
"That's it Will, give mommy all your cum. Make her your dirty little cum-slut. Ram that thick cock in my whore mouth and give me all that seed."
She was barely audible, as she whispered these things to herself, as her mind wove increasingly perverted scenarios, though every one involved her son in some way. Midway through a particularly deviant scenario, her husband interrupted her reverie.
"So, turns out I'm going to have to leave for Las Vegas this week, Chuck wants me there to help demo our new products at the expo."
"Nnng... not now Steve... nng"
"I just thought I'd let you know so you could get started packing for me, I have to wrap up some last minute presentations or I'd do it myself."
If the man wasn't going to help her cum, couldn't he at least take a hint and not actively prevent her from helping herself? At that moment, her vibrator finally gave up the ghost, its batteries now completely drained. If she were a man, she'd be bemoaning being blue-balled twice in one night. It wasn't quite the same, but by god if she wouldn't hump the first vaguely phallic object to present itself.
"Fine!"
In a huff, she threw on her robe, tying it loosely, and left their bedroom, still horny as hell.
Steve, meanwhile, had already opened up his laptop and begun working.
"Huh, wonder what her problem is..."

Will flushed the toilet, his erotic excretions slowly whirling away. Weeks ago, his mom had finally accepted his apology, and things had more or less gone back to normal. Not entirely though. For one thing, his parents had been going at it like rabbits lately. They tried to be sneaky about it, but he didn't think they were aware of just how much of their escapades carried through the ceiling. Whether he was gaming or writing, he'd hear his mom's moans quite clearly and immediately feel compelled to wank off to the sounds of her passion. It never seemed to last long enough, though he was able to finish himself off just remembering her in that tiny thong covered in cum. His cum. He felt himself beginning to harden, and quickly changed his thoughts. Deviant he might be, but he still felt a degree of shame over that whole encounter.
He tucked his semi-hard member into his shorts awkwardly and prepared to walk to his room. Halfway there, his mom, wearing only a precariously secured silk robe walked into him. She looked vaguely upset and highly distracted as he braced and caught her in his arms before she could bowl him over. She smelled strongly of sex and sweat, and he reluctantly let her go.
"I'm so sorry baby, your dad's just got an unexpected trip and he expects me to help pack him up. Last thing I want to do is knock you on your ass right as your healing up from your last fall."
She was looking up at him apologetically, and he swore he saw a single tear forming in one eye. Unexpectedly she pulled him back in for a tight hug. He was rapidly leaving his state of semi-arousal behind as he felt the large globes of her chest press against his abs. If she noticed his cock harden and press against her, she didn't hint at it at least. As he wrapped his arms around her back, he heard a small sob.
"I'm sorry, it's just... I feel like I'm just a bad wife and a worse mother sometimes. I--"
Will cut in, "Absolutely not! You're perfect mom, you spoil both dad and me. We're lucky to have you!"
She pulled her head away from his chest, affirming that he really meant that. In truth, she felt like that couldn't be true as it'd taken every ounce of her will power to avoid dryhumping the hell out of that length of pipe he'd pressed into her.
"Thanks dear. I'm lucky to have you too. I think about you a lot."
She wasn't sure why she added that last part. Or rather, she knew, but cringed internally that she'd let it slip.
"Well, I've gotta go get your dad set up at any rate."
Will leaned down to kiss his mother on the cheek, while she went to reciprocate. Somehow, their wires got crossed and Will felt his mothers lips press against his. It was the most chaste bit of contact, but Lisa felt her son's cock twitch against her even as her own pussy seemed to be salivating at the prospect. They briefly made eye contact, before the moment was ruined by her husband stomping up the stairs. They both quickly pulled away from each other, each trying to hide their blushes and other signs of arousal from each other, from Steve, and even from themselves to a degree.
Will left his parents at the stairway as he went back to his room, resigned once more to beating his meat. Though now he thought he just might have one more experience to reminisce on.

The rest of the week passed by without incident, and they had taken his dad to the airport for his conference. On the drive back, his mom grabbed his hand and chatted up a storm as they made their way home. While his mom was cheerfully expounding on any number of topics, he barely followed, he had broken out into a nervous sweat. He put on a good face, and tried to be responsive, but internally he was waging a war.
