Improve them - and yourself - physically

It's time to test your theory about physiologically, and anatomically, changing those you influenced.

“Cassy; gosh, you are so beautiful, and such a good lover, and I hope you know that – but don’t be arrogant! I want you to remain just as you are, in your everyday personality, and in your cute but ravenous role as my lover. Amy; you are gorgeous, and always have been, but I think your amazing personality and sexuality deserve even more. Your breasts will grow by two sizes, but will be even more perky and shapely than they already are. Your arms, legs and body will be slim and toned, regardless of whether you exercise or what you eat – but you’ll still want to exercise for the fun and clarity of mind it affords you (that applies to you too, Cassy). Your cheeks and face will lose just a little bit of their chubbiness, to be sleeker and more streamlined. You will grow a couple of inches vertically, but not horizontally, your legs getting slightly longer in proportion to your body. Neither of you will need to sleep any longer, though you can do it as before, and you're immune to all diseases [why not, you think]. Now that you freeze on my command, I no longer want you to freeze when receiving my cum. You'll both always have perfectly smooth, unblemished skin, soft, moist lips and mouth. Your pussies will always be wet when you are around me. I know that’s a lot of changes, but I know your diet supplies more than enough energy to enable it, and I want you to not even notice the changes as they happen, but only once your transformation is complete. Neither of you girls will ever notice or think anything is unusual if you see me cause someone to freeze in front of you, like you are now. Now, enjoy your orgasm Cassy! Unfreeze.”

With a start, Cassy screams at the top of her voice in glorious ecstasy, her body throbbing, her pussy pulsing furiously around your cock, until she collapses against the pillows, eyes closed as she processes the uninhibited pleasure that had overwhelmed her brain. Even Amy let out a moan as she cummed hard.

The three of you spend the rest of the night fucking every way you can possibly think of; you would fuck Cassy whilst she ate Amy’s pussy and Amy kisses you ravenously. Then Cassy would give you a blowjob whilst Amy finger-fucked her. Cassy would lie on top of Amy at the edge of the bed, both presenting their dripping pussies for you to alternate between as you pleased. You discover that you can telepathically make them orgasm with a thought, and just as easily bring back their sexual fervour as take it away, as long as they've recently had your cum or precum inside them. You can even make them horny specifically for you – now you try, it's easy; instinctive almost. There is so much potential here! You count your lucky stars that you, of all people, have been blessed with such gifts. You even allow Cassy and Amy to remember you have it, but order them to never give the secret away to anyone.

After just a few hours, Amy's breasts are noticeably larger, and this success leads you to contemplate whether you could even enhance your own physique. You're fairly fit, and your cock certainly stretches out your girls, but the temptation to go further is so great. Besides, if you give yourself a huge cock, you can easily reprogram your girls to be able to take it.

The thought of having to have your own cum in your throat or ass is a little uncomfortable, but you're placated knowing it gives intense pleasure and tastes delicious. When you tell Amy and Cassy what you want to do, they jump on the idea with joy. Before you know it, they're both pleasuring your shaft simultaneously, tongues and lips caressing all over your erogenous centers whilst they fondle your balls and squeeze your ass. It doesn't take long before the intense stimulation sends you over the edge, and you cum all over their faces.

As soon as your spurting finishes, the girls immediately start devouring one another, insatiably licking one another's faces until they have collected every drop of your semen. As Cassy swallows, immediately orgasming with a scream, Amy slowly crawls up your body, feeling every inch of your skin as she seductively rises to your face. Finally, her emerald eyes meet yours, and she kisses you deeply. Her tongue ventures deep into your mouth; the taste of your product is just as fantastic as Amy had promised, and you have no trouble swallowing.

You're caught off guard by your own sudden orgasm, and the sensation of lips around your cock where there hadn't been an instant before. You look down to see Cassy swallowing load after load of your cum down her elegant throat, her crystal-blue eyes gazing adoringly up at you.

"Well?" you ask, as your orgasm finally subsides.

"I did what you asked, master," nods Amy. "You froze just like you said you would, and I read you the script you gave me."

You smile victoriously, and try to harden your shaft. Not only does it instantly stand to attention, it grows far beyond its usual size, until it's thicker and longer than your forearm, and visibly throbbing. Being able to control every aspect of your dick at will - length, girth, hardness, ejaculation time and volume - was the first thing that came to mind when you decided how to reprogram yourself. You can already feel the muscles across your entire body growing, consuming fat as they grow, as you slowly develop into a man more physically perfect than a Calvin Klein model. You've also given yourself the same physiological perfection as your girls - at least, as far as is biologically possible - and a few further sexual enhancements. Firstly, a mild degree of control over the release of your pheromones. Secondly, unlimited stamina and libido, unless you want to turn it down. You're planning to do a lot of fucking over the next few days, after all, which is why you gave yourself a third ability - to control at will whether your cum impregnates your partner.

You wake at sunrise with a gorgeous, petite girl in each arm, laid out in the master bed, each of them cuddling close to you. You’d had barely an hour’s sleep.
