“Your ass looks fantastic.”
She knew it did. It had always looked fantastic, but now there was a special power to the increased size and hardness of her buttocks.
Vanessa also felt a special heat in her heart, knowing that a man like that rarely complimented a female on her beauty. It literally made her stop, glance at him slightly, and reply in a damsel’s tone:
“I hope to craft this into an ass even your dick can’t break.”
She was met with an arrogant laugh: “go dreaming, girl.” His face turned slightly demonic. “When I fuck you, you will not wake up again. Not today, not this week.”
Her heart throbbed. There was a reason they were both on those mysterious catacombs, fucking through a mountain of women to see who of them was more virile: they were preparing their bodies for each other… so they could fuck like no beast on Earth ever could.
«Horses and bulls would never have the power we will have… when we fuck each other again.» She realized, knowing that the three women in front of her were more than just pleasure; they were her warm-up.
She stopped before them and flexed her abs. The eight amazing muscles burst and rippled in her belly.
“Look.” She commanded, and the three ladies started losing their breaths. They were all tall and muscular –the smallest of them measuring 5’8ft-tall and 190 pounds—, yet they felt terrified next to the power they saw growing in front of them.
Even the biggest of them –a 6’1ft-tall, 220-pound redhead—couldn’t help but to gulp and shake a little as she saw Vanessa literally vibrate and grow before her eyes.
“Ooarr!!” Vanessa roared. Power burst from her every muscle. “Fuck yeah!!” She flexed her arms. Those beauties bulged like mountains, and there was yet more to cum. “Ooh, fuck… fuck yeaaah!!” She crossed her arms over her head and flexed them at the same time as her abs, which rippled and throbbed with a plethora of thick veins multiplying all over her body.
Her thighs bloated like balloons, their infinite fibers swelling and shaking as they literally multiplied and kept their added size and weight.
Vanessa saw the floor getting a little more distant every time she blinked. She was adding inches to her body as she focused her blood, her energy, her power on every single muscle. Even her cunt seemed to get more ripped and firm. Her clit, which had always been of regular size, bulged and throbbed like a little finger, so hard it could cut through glass and, after a few more minutes, iron.
“Roooaaarr!!!” Gushes of air burst from her body as her muscles rippled and the giantess literally added pounds and inches to her body before the astonished gazes of her admirers. Even Gaston was amazed, preferring to rest that piece of flesh in his lap than to fuck her while Vanessa was gaining so much muscle.
«She’s mastering the art of muscle growth!» He lifted his eyebrows. «I never thought anyone else could do this!»
Vanessa gave such a mighty roar that the walls of the catacombs cracked and pieces of the ceiling fell around her. She spread her arms, which remained flexed as hard as they could in that position, and then flexed her back, which became a wall of muscles and veins for Gaston’s delighted gaze.
“Fuck!!” She puffed steam through her nostrils. The three women before her felt wobbly and unbalanced. Their legs shook and their cunts throbbed. They literally couldn’t breathe straight when looking at that obscene demonstration of power.
Vanessa flexed her biceps again, feeling her muscles engorge just as her tits both grew harder and fuller. Scorching milk was being added inside them in the tune of gallons per minute! At that point, her milk had condensed to a creamy state, only less dense and consistent than the jizz of her mighty lover, who still admired her from behind.
Conscious that she was also putting on a show for him, she readied her legs for the most spectacular display of power yet. “You said you liked my ass? Good. Then… get!… this!!” She flexed her legs, her calves, her thighs, and her buttocks roared as the rippling of her muscles finally got to them, flexing them so hard and mightily there was a loud thud and a whiplash coming from her behind. “Oooh, fuuuuck!!!” The catacombs quaked again as she roared. The flex was so powerful her whole body ached like one massive, all-encompassing cramp.
