"...we play a different game," Lisa says, her eyes flashing. You gulp. She takes a step towards you, her 8'3 body shaking the earth with each footfall. But then, she did something unexpected. Instead of picking you up like a rag doll, she lowers herself to the ground and lays down.
"I'm going to lay down here, and I want you to do your best to harm me. I won't even flex." She grins at your disturbed expression. "Come on, I want to see you try and stop me! And don't be afraid to go all out, I want to see everything you've got."
You glance worriedly at her, but do as she says, grabbing the bar from your weights and bringing it over to her. With as much force as you can muster, you raise it over your head and bring it clanging down onto her chest. The bar immediately bends at a right angle, and Lisa laughs at you. "Seriously, is that the best you can do?"
Your jaw sets hard at her taunting. You toss aside the bar, grabbing the fire poker from the fireplace, and lifting it above her abs. As you bring it down, you can feel the sharp tip puncture her skin, just briefly, before it stops. She cries in pain, and you pull the poker out, watching the puncture wound rapidly heal in the glow of the amulet. Through the pain, Lisa smiles a wolfish, mad grin. "Yes, that's it! I want you to hurt me, John! Again!"
At her request, you bring the poker down again, but this time it bounces harmlessly off her toughened skin. She howls, "Yes, make me stronger!"
You grab a knife off the kitchen counter and ram it into her as many times as you can. The first time is deep, but as you stab her prone body over and over again, the cuts get shallower and shallower, before the knife crumples in your hand to a misshapen lump of metal, undone by the might of her incredibly tough skin. And as you watch, the time it takes for her to heal from her wounds grows shorter and shorter as her body's healing factor becomes superhuman. Lisa cranes her neck to look you in the eye as a smug grin breaks over her face. "My, my, it looks like I'm winning this game after all." She stokes your destructive competitiveness, pushing your buttons expertly to manipulate you into making her even stronger.
You glower at her. "I'm not done yet!" You look around for something else. Aha! The diamond ring you gave Lisa when you proposed to her. It popped off her finger as her meaty digits broke through the metal, but that left the diamond completely free, with a nice sharp edge. You scrabble around on the floor until you find it, and then bring it to Lisa's cheek. You scratch over it, watching a thin line of blood follow your movements before disappearing as fast as it appeared. With every stroke, you have to apply more and more pressure to break the skin, until finally the gem shatters from the sheer toughness of Lisa's skin. She tuts in disappointment.
"Such a shame, I liked that ring." She sighs. "Oh well, at least you have something far more valuable, little man."
In a burst of creativity, you grab the bent metal bar and walk over to Lisa's legs. She raises an eyebrow at you. "You've already tried that, remember?"
You grin wickedly. "Oh, I know. But I haven't tried this yet!"
With a laugh, you ram the metal bar into your fiancée's pussy. Lisa moans at the sudden intrusion, arching her back as you push more and more into her cavernous pussy. Her fingers rend claw marks into the floorboards as she accepts inch after inch, the metal scraping her inner walls in a unique sensation both pleasurable and painful. Once the pole is nearly a foot into her, you find her cervix, and quickly push through with a hard shove, letting Lisa scream as your assault continues. But soon, her cries of pain turn into whimpers of pleasure, not only as her body turns off any pain receptors in her vagina, but also as your assault slows as her walls grip the pole tighter. Her muscles grow around her mound, contracting it so impossibly small that it grinds the metal to dust, and you're left with just half the bar you used to have. You can visibly see the muscles moving below the skin as Lisa's vagina compresses the metal smaller and smaller. Her back arches as she cums, and the flood of fluid washes a tiny, marble-sized ball of metal towards you. It's the foot and a half of iron you pushed into her, crushed into a singular, super-dense ball. But when you go to touch it, you find it's incredibly hot. Apparently, fitting so many atoms into such little space has made it into a sort of miniature sun. Great, now her pussy is strong enough to crush steel, and it can
Lisa gives a deranged laugh as she recovers from the afterglow. Her breaths are ragged, and you can see her muscles twitching below the skin. "I like the way you think, John," she mutters. Her eyes are blown wide. "Holy crap that was intense. Best orgasm of my life!"
Then, she rolls over, shaking the floor as she does so, and puts her chin on her hands. "So, what's next?"
