PART 2 - Andrea
I woke up before Simon did the next morning, and I lay there for quite some time thinking about the events of the night before. I had been doubtful, to say the least, when he'd told me about this amazing "Master PC" computer program that he'd gotten hold of. "It lets you do anything you want to other people or yourself", he'd said; "Mental, emotional, or physical changes, anything you can think of, it can do!" Yeah, right. I figured he was playing a game, and that we'd end up going home and pretending that we could control each other's actions and thoughts. And I admit, it was getting me pretty hot. I've always had a liking for dominant sexual partners - nothing silly and overdone, just guys (and the occasional girl) who enjoyed taking the lead in treating me like their "slut" or "whore" or "cunt", and would "make" me suck their cocks, get down on all fours for them, and so on. Nothing I didn't want to do anyway, of course, but I liked talking that way about and during sex. So I was starting to get into this fantasy about "mind control"; I could go along with that, no problem, and we'd just pretend that he'd made my boobs into double D's or whatever.
Then we got home and he proved he was telling the truth, first by turning my hair from short and brown into very long and blonde with a few clicks on the computer and then by giving me an irresistible compulsion to undress (except for my boots and fishnets, of course; that boy was so predictable sometimes!). Well, if I'd been getting a bit hot at the idea of a game, this put me into overdrive. By the end of the evening, I'd had several mind-blowing orgasms, two of which were triggered just by Simon cumming in my mouth or pussy, thanks to Master PC and Simon's thoughtfulness. I think I could safely say that it had been a really, really good night. Although in retrospect I had maybe overdone it with my last computer-enforced instruction to Simon, which had led to him fucking me senseless in the bedroom. Good thing he'd cum eventually, because I think he would have kept going all night if he hadn't.
But that had been hours ago, and all this thinking about the fun we'd had was bringing on a familiar sensation between my legs; when I ran a finger along my slit it came up very wet. After licking it off - I always did enjoy my own taste, though it was best when I could lick it off Simon's cock - I put that hand back down, dipping two fingers into my pussy while rubbing the heel of my hand on my clit. With my other hand, I pushed the covers down to expose Simon fast asleep beside me. He was lying on his back, one arm thrown up over his head while the other dangled over the far side of the bed. His cock, I was happy to see, was already pretty hard - dreaming good dreams, I suppose - so I started stroking it with my free hand, getting it that little bit harder and longer. Simon only shifted in his sleep.
Reluctantly removing my fingers from my pussy, I shifted around to get on my knees and took the head of his cock into my mouth. It was already covered with precum, which I greedily licked off before pushing my lips down his shaft, gripping it at the base with both hands. I quickly got into a rhythm, stroking with my hands while working my mouth up and down as far as I could. I mentally kicked myself for not grabbing my vibrator from the bedside table, because my pussy was feeling really empty right about then. But I wasn't about to stop what I was doing at that point.
Simon must have woken up at some point, because his hands came up to grasp my head as I sucked on his cock. "Oh yeah baby," he murmured, "Just like that." I redoubled my efforts, because I could tell by his grunts and the way his hips were twitching that he was close to cumming. I sealed my lips tight around his cockhead and pumped harder with both hands until I felt him shudder and stiffen. And as the first spurt of salty jizz hit the back of my throat, I was suddenly hit with a powerful orgasm of my own. Part of my mind calmly observed that I should have expected that; after all, Simon had set it up the night before that I'd orgasm when his cum hit me, but I'd really forgotten about that in the heat of the moment. Not that I was complaining! I kept on cumming until the last drops oozed out of Simon's cock into my mouth. It was only then that I could swallow it all down and move up to give Simon a good morning kiss. He gave me a lazy grin as he stroked my back. "Thinking good thoughts m'dear?" he asked.
I snuggled into him. "For some reason sex was on my mind this morning," I answered. "Can't imagine why that would be!"
"Gosh," he answered, "I've got no idea either. But somehow I've got a feeling that the whole day's going to be like that." He gave my ass a light slap. "In the meantime, I'm pretty damn hungry. How about you?"
I was pretty hungry too, so we got out of bed. Simon went to take a shower while I headed for the kitchen. That's when I discovered an unexpected side-effect of the fun the night before: I couldn't put on my dressing gown. When I tried, I was overwhelmed by a stifling feeling of suffocation, and couldn't resist the urge to take it right off again. Clearly, Simon's command was still keeping me from wearing any clothing above the legs. Note to self: unless they're self-limiting, Master PC commands just keep going until and unless specifically cancelled. Fortunately, it was a warm morning, I'm not a particularly shy person, and there was no-one else around anyway. So I just went out to the kitchen as I was to make some coffee and put on some toast, and then went into the study and canceled the leftover commands from the night before. Just a second too late it occurred to me that I should have left the command for me to cum whenever Simon came on me (and for that matter, his trigger phrase for me to deep throat him). No need to remove those - they were fun! But it was too late, and it wouldn't have been the same, somehow, if I'd put them back on myself. Part of the experience, I decided, was letting someone else do those kinds of things to you. Ah well, maybe he'd decide to replace them later. I could always hope!
I didn't cancel the command that kept Simon from wearing anything though. Why shouldn't he get to savour the experience too? I couldn't help but grin when I heard him yelp in surprise from the bathroom after finishing his shower. He came through the kitchen on the way to the study a minute later, start naked. He gave me a cheeky grin as he went by, carrying his bathrobe with him. He came back into the kitchen a moment later with his robe on, and we settled down to breakfast. As we ate, we discussed what we had here and decided on a plan of attack. Once we were done eating, we refilled our coffee mugs and moved back into the study to begin what turned out to be a most educational morning. Simon settled down with the computer, since he had more experience in using Master PC; I'd get more practice later (oh, would I!).
For all of the sexual fun we'd had the night before, we actually started out quite prosaically, by using Master PC to make some general improvements to ourselves. Nothing really drastic for the most part: just increasing our general levels of fitness and making ourselves perfectly healthy. Let me tell you, it's amazing how many little aches and pains you accumulate just by getting older that just blend into the background of your life until you scarcely notice them. But once they were gone, well, what a difference! Simon's slight limp from an old work injury, my slightly blurry eyesight - all gone. We deliberately kept it to things that wouldn't be immediately apparent to other people. We weren't sure how we'd explain it if, for instance, Simon turned up to his next family gathering as a sudden muscle man. Fortunately, I wasn't really that into the muscle man look.
Once all that was taken care of, though, it was time to get a bit more creative. For this part, Simon and I agreed that I'd let him decide what changes should be made in me, and I'd decide what changes he should have. And more importantly, we wouldn't tell the other one what changes we were making. (Sure, some physical stuff would be obvious, but not all of it - stuff like reactions or sensitivity could be a pleasant surprise later). It was a real rush to be doing this with someone that I trusted implicitly, and who trusted me in return. I really wasn't worried that Simon would go mental and power-mad and do things that I wouldn't like. After all, he'd already had the chance to do that if he'd wanted to, right?
He started off by making me wait. He told me to strip off my dressing gown and stand in the middle of the room while he walked around me, looking at me from every angle. Without saying a word, he sat down on the couch with the computer open, and looked me up and down some more. He had a funny expression, like he was trying to keep a big grin off his face. The way he kept shifting around made me think that he had a hard cock underneath his bathrobe. Finally he nodded to himself, like he'd come to a decision, and started tapping on the computer. I just stood there, biting my lip to keep from squealing in excitement. Waiting to see what Simon would do with me, do to me, was one of the hottest things I'd ever experienced.
At first I didn't notice any change. I was already turned on, already had hard nipples, already had a damp pussy. None of that changed. What he'd done wasn't clear until he told me to come over to stand beside him. Once I'd done that, he reached up casually and cupped my right tit in his hand. And I nearly fainted. Just that simple touch felt fantastically erotic. My already considerable level of arousal abruptly shot up, to a level that I wouldn't normally reach without someone spending a good while with their tongue between my legs.
Simon couldn't help the grin now, when he saw my reaction. "I need to test the changes, don't I?" he asked innocently. "Have to make sure I've got it right, you know." I caught my breath and nodded quickly, and almost fell over when he added his other hand onto my other breast, and then started squeezing lightly before moving his attention on to my nipples. "Don't touch yourself!" he ordered as he noticed my hands slipping down between my legs. "You'll spoil the test!"
