No: you evolve into something more...

You orgasm hard, feeling your dick twitching as your virgin pussy spasms wildly. The sensation is fantastic, and you can't help but moan, long and loud.

When the quakes emanating from your abdomen finally subside, you try to calm yourself, breathing heavily, thinking zen thoughts. However, instead of diminishing, your sexual urges begin to grow again, and your panting grows heavier and more throaty, not lighter. You begin to panic - what if you lose your mind to this?

"Cassy, how did you reprogram me? Did you say anything different to what I told you to? Quickly, I don't have much time!"

The petite blonde girl just puts a finger against her lips coquettishly and giggles. "I told you to become my goddess of sex," she grins evilly. "I told you to evolve into the perfect physical specimen, to always hunger for sex, and for your body to adapt to fulfill your every desire." Too late, you realise you never compelled Amy and Cassy to obey your every command to the letter, and now this sex-crazed girl has used your own powers against you.

"No, listen, we need to stop this," you say frantically, feeling your body growing and changing, the rushing of blood in your ears growing louder. "We have to undo this. Before I... I..." You trail off, trying to focus, trying to remember what you wanted to do, to see through the haze. You wanted to... go back to who you were before? What? Why would you want that? Cassy's helped you push past your limits, to fulfill your potential. Your potential...

Your eyes alight on Cassy's small body. She seems to be shrinking beneath you - or maybe you're growing. You don't care. All you know is you see her young, nubile body, and you have to fuck it.

You lift the girl up and slam her onto your cock, feeling it inflate back to its previous size, once again ripping apart Cassy's small vagina. She half-screams, half-laughs, in wild ecstasy. Her body feels so good on you... but you hunger for more. You always hunger for more. You grab her waist firmly, and ram into her suspended body, gasping as your last inhibitions fade away, and your shaft expands rapidly. You feel your head smashing through first her cervix, then start stretching her uterus impossibly long, the shape of your head bulging from her pale belly. Tears stream from Cassy's eyes as her hips are dislocated by your growing girth, plowing through her body, which is only capable of withstanding this punishment thanks to her enhanced healing. Yet she still manages to yell words of encouragement between her screaming moans:

"YESSSSS, AYYYEEEEEE, Mikaela, ohhhhh Mikaela, yes, fuck MEEEEEEEEE..."

You keep pounding her, using your body like a ragdoll. You're distracted from a moment as your head bumps the ceiling - clearly you've grown quite a lot; your new body is tall and rippling with powerful muscles, but still maintains feminine curves in proportion to its size. You once again thank Cassy for helping you see past your inhibitions, for having the vision to see what you could become. Then a particularly loud scream breaks your thoughts, and you're consumed by lust once again. You ram Cassy against your bucking hips faster than humanly possible, grinning wildly as you feel your huge weapon growing even further inside its uterus sheath, pushing aside organs as it does so, until finally you're bumping against her shoulder blades. The stimulation is finally enough, and you explode inside her, your huge cock lifting Cassy's body with every pulse. Sperm shoots from her anus under pressure, and erupts from her mouth and nose in gallons. You must have messed up her anatomy pretty badly. Her eyes widen at the sensation, then roll up inside her head as her spasming body finally goes limp. You're impressed she lasted this long.

You throw Cassy off your shaft like a rag doll, your sperm still oozing from every one of her holes. You barely register your two-foot length, whose weight is no problem thanks to your increased strength, as you swing around to Amy. The redhead is kneeling beneath you, looking up at you with awe.

When the sun rises, you stare at it as thoughtfully as your alpha brain can manage. You've fucked your two sex-toys continuously, and tried to make them bigger to match you, but they only grow to just over six feet, and no matter how much you reprogram them to recover faster, they always end up **** on the ground for several minutes after each fuck. You can't wait that long. You realise what you need is more pussies to fuck.
