When he finally woke up, the first thing Will saw was a naked, massively muscled, cum-soaked clit staring right at him, bulging and flexing in accordance with some sense of wait, of anticipation. The dull pain in the back of his head made Will realise he'd fallen against the bathroom wall after the riotous oral sex with Mabel. It was upon recalling that event that it suddenly dawned on him who stood in wait ahead.
"You're not exactly that good a pleaser, boy." Mabel crossed her arms in frustration, biceps humorously mashing against one another as they vainly vied for space; when one arm pushed to make room for itself, the other only seemed to counter with even more strength, adding pressure to the elderly woman's body. Her comically large tits nearly spilt over the equally gargantuan forearms. "You were out cold in less than a minute."
Will didn't know how to exactly respond to that. It went without saying he didn't have even half as much sexual experience as the woman before him, but that came with practice. Mabel continued to look down at him contemptibly, regardless, a bare foot pressed against his flaccid sack. It would probably be a while before he was hard again. Mabel took everything he had to offer and it more than showed. Just like her daughter had one earlier, Mabel's gut was still filled to the brim with Will's load. It had been several hours since he and Mabel had sex, yet she still - somehow - retained the rotund stomach.
"I've been waiting for you to wake to show this." She took a few steps back, her triceps casually scraping against and chipping away at the tiles in the process, and crunched down into an abs and thighs pose. The noise Will heard was something akin to water sloshing - he could actually hear his load swirl around inside the powerful woman as she offered an erotic grin at the youthful lover. It wasn't long before Will noticed her gut was starting to shrink as ifβ as if his load was disappearing from its otherwise perfectly sculpted confines. Little by little her stomach thinned out; little by little her abs became more prominent. The change became noticeable through the otherworldly fidgeting of the woman's belly as if something inside it was directly influencing the reducing girth.
Deliberate moans of pleasure came from Mabel as the shrinking came to an end, revealing her six-pack abdominals in all their unmatched glory. She couldn't stop herself from running a hand across their cobbled perfection, her digits moving ever closer to the pulsing clit she was proud to possess. She might've thinned out her gut to bring it back to its former brilliance, but the fun didn't end there. Besides, where exactly did Will's load go? It didn't just vanish - did it?
Mabel's smirk seemed to imply she knew exactly what question was going through Will's head. She casually raised her right arm up into a flex and listened as, knowingly, her already colossal bicep started becoming even more so, gently rumbling as the wrinkled skin became taut and bloated with she-beef piling onto itself, thrumming as mass filled every part of her existence; arms, legs, shoulders, back, chest... It soon became clear to Will that his load was the catalyst to Mabel's growth. He watched in awe as, much like everything else about the woman, her clit soon shared in the increase in mass, twitching and throbbing like it did hours ago. How could someone so old be this sexually active, let alone ripped? It was perhaps a question for the ages. He dared to doubt if she could become even more so.
Mabel approached and picked him up with laughable ease, the naked Will wordlessly complying with her actions far too enamoured by the woman's general existence and inhuman size to do anything else. His cock pressed against her swollen rippling shoulder, he stared at the floor shifting from tile to carpet as Mabel carried him into the bedroom where Ellen awaited, equally naked and ready as her mother, but nowhere near as large or aroused. The two women stood shoulder to shoulder as Will positioned himself on the bed, trying to make sense of everything. He had a rough idea of what was being hyped up - something that involved the mother and daughter.
"It's unfortunate you lasted only a minute back there, kiddo. But maybe this'll get you stiff as a board."
The next thing Will saw more than got him stiff; a delicate river of precum trickled down his shaft as Mabel and Ellen locked lips in such a way that it was clear they'd both done this before and had considerable experience with it. The moans that came between their sporadic kisses suggested they liked it too. Will had watched lesbian porn videos over the years but they were next to nothing compared to this. Using a hand, Mabel delicately lifted Ellen's left leg over her side and groped the quad feverishly, while Ellen squeezed her mother's left nipple, their individual muscled bodies close to grinding together. It was clear they were slowly easing into that.
Mabel urged her daughter's body backwards, smashing it into the wall so that it cracked like an egg, her powerful back muscles rippling from the motion. Will traced the cracks curiously, watching them develop and grow until the skirting at the bottom split just an inch away from the carpet. The two women picked up the pace of their lovemaking, their pussy muscles grinding and smacking together in incessant lust and desire. Indecipherable mutters came from the mother before a knowing grin spread across Ellen's lips, which was swiftly followed by her going down on both knees and licking her mother's genitalia. Was there truly no boundary the women would cross to ensure arousal came to Will?
The rhythmical licks came in sync with his masturbatory strokes, shameless as the women's blatant incestuous love. As he yearned to continue watching, Mabel enticed Will further by pulling her arms into a back double bicep pose that saw the 90-plus inched muscles in question rise to inhuman levels, their peaks climbing above the woman's head. She caught Will's awed gaze reflecting through it and made sure to offer a suggestive pout. And just like that, she held him firmly in the palm of her hand.
Magnetically drawn to them, Will reached for Mabel's arms and felt them wherever he could, knowing all to well it would be impossible for him to reach their mighty peaks. Every gentle squeeze aroused him and the gargantuan woman further, and before he knew it, his newfound erection pressed against her glutes, teasing her hole with the thickness of her meatus. As she flexed her asshole to spread open, it became clear Will's cock was a perfect fit; a pleasured moan escaped the woman's lips as she turned her arm back to gently stroke his shaft while Ellen maintained her licks from below.
"Round two then?" Mabel smirked at Will's reflection.
