Kim grinned and nodded, laughing and rubbing the back of her head. "Hehe, yeah, I guess we can do that." After this she guessed they could just reset everything anyway, and just insert changes again to happen slowly over the course of one or two weeks so no one really noticed right away and would probably just assume that -finally after so many years- he had a growth spurt.
As he worked at the computer she only smiled, sitting very patiently as her eyes wandered over his body. She couldn't really see much at all though, besides the tiny peek at his abdomen and what little of his legs were poking out of his pant sleeves from being so tall. There was certainly a great bulge in his pants though, and as much as she loved seeing it there between his legs she had to wonder if it brought him any discomfort or pain being bound like that. She frowned a mere moment, his clothes were pretty tight, poor thing could hardly move. She decided she knew what she would do next the instant she got her turn at the computer, certain both of them would enjoy it.
"Having fun?" she smiled at him, noticing he was taking even longer than she was when she saw him turn toward her. He seemed so nervous, it was adorable. One thing she always liked about him was how cute he was, he was always so shy about things and not at all like any of the jerks she ever dated. Would she have asked him out ages ago? Yes, but in all honesty, she had trouble admitting to herself she never had the courage to because of what would happen to both of them if people found out. Especially any of her ex-boyfriends with as jealous some of them tended to be, worse knowing that she had always been friends with him. They would think she had been cheating and go after the poor dear! "Let me try and gu-- o- oh." Kim stopped herself short, able to feel something happening. Well, a couple of things.
The changes seemed to happen in order, starting with her hair: It was something she had to guess at first, it was relatively hard to feel happening, until suddenly it began to feel as if someone had started to massage her scalp gently. Her platinum hair started to lengthen, hair that just previously sat above her shoulders extending, falling on top of them and growing longer still. Full locks cascaded passed her back in light waves until it fell into a small heap on the floor at her feet. She touched her head, running a hand through some of it before pulling it over her shoulder to see for herself how long it had gotten. She giggled at him. That dork! She knew he had hated it when she cut her hair so short but she never realized he had wanted it grown out this long! It kind of reminded her of Rapunzel. She wondered quickly if this was the only change she made until something much more noticeable started to happen.
Kim looked down at her breasts, feeling a tingling sensation fill her at her core. It felt warm and when she went to touch them she shivered, unable to let out a tiny moan of surprise. At her own touch -and through her tank top no less- she felt her nipples go rock hard, rising and poking at the fabric which had already been stretched slightly because of her new endowments. She started to rub them once she realized her nipples were growing longer, and pleasurably so, inching out further and further creating vast tents in the front of her shirt. Kim made no hesitation to moan now, her body quivering with pleasure. Her hands couldn't help but run her fingers over them, delicately pinching each one by the time they stopped growing and right in front of him! They were so much more sensitive! If he kept this up she was going to get so horny, she wasn't going to be able to keep thinking straight. "They're so long now," she mused. "Perfect size for sucking." It took an immense amount of will to pull away, getting up to take her seat at the computer until she realized he wasn't finished. Her shorts were starting to feel tighter.
"Nngh, w-what--" Kim felt her ass beginning to fill out. It had already been pretty round and perky, for someone her size anyway, but slowly she could feel her ass literally inflating. She touched each cheek, moaning again when she realized it felt so great. Each palm of her hand feeling her ass rise, growing out. She winced when she felt her shorts begin to tighten under the strain. They weren't by any of the means stretchy, so as her ass continued to fill out the steams started to strain more and more, the waist band quickly beginning to dig into her. Not too much, but certainly causing discomfort. Still, she kept rubbing her ass, turning around and wagging it at Nate so he could watch it grow for himself. Then before she knew it, her shorts gave in. With a massive and audible RIIIIIIIP!! her shorts burst open at the back and sides, falling to the ground in pieces. Kim gasped, and when she looked at her ass again she noticed each ass cheek had grown to the size of basketballs, yet they remained perfect, not just firm but perky too. "Ah! I-It's gotten so biiiig, nngh," She groaned with pleasure as she gave her hands free-reign, inviting her friend Nate to cop a feel. She winked at him, her face obviously having turned pink from her arousal and she was panting slightly, one of her hands having returned to her breasts, though he couldn't see it unless he looked right over her. "G- go ahead, feel it. I can't have all the fun can I?" Her underwear, a modest pair of panties, looked like a small thong at this rate, buried and lost between her gigantic ass cheeks. The waist band seemed awfully strained also, looking like it was literally about ready to rip and tear if she moved too much.
As if to encourage him to feel what he wanted, she backed into Nate, ass rubbing against him and his crotch briefly. "I think it's my turn again to go at it on the computer, okay?"
