This choice: We're going upstairs to have some 'fun' *wink* • Go Back...Chapter #4So that's what did it... by: RenV   The young man racked his brain, struggling to think of something that he and his new, older cousin could do together. Dan didn't really know the 14-year old version of Laura all that well, or at all really, so he had no idea what kind of things she actually liked. Maybe he could try bringing up one of the things he knew that she used to like? No, that might be even lamer than just taking a shot in the dark. What did girls his age usually like to do anyway, besides talk about make-up or their hair or something else he didn't think he could stand. The longer these deliberations went on in Dan's head, the more his eyes drifted in the direction of his cousin, her attractive new body more alluring that he was willing to admit. Her legs were so long that it seemed like they went on for days, but they weren't skinny like the ones he'd seen on some other tall girls. These were full and curvaceous, her yoga pants almost seeming to be too small to hold them properly, the garment barely able to reach her ankles. Combined with her flat tummy, her mature face, and the utterly jaw-dropping size of her boobs, Laura was maybe the most attractive 'girl' that he'd ever seen. Before he even realized what he was doing, Dan accidently voiced aloud a thought that he'd meant to keep inside his head forever.
"We're going upstairs to have some 'fun'."
A silent few seconds passed, Dan's mortified face turning the brightest red it had ever been, the boy unable to meet the gaze of any of the family members sitting with him at the table. Had he really just said that? Yes, he'd heard the words the moment that they'd left his mouth; he'd even added the extra inflection to 'fun', which meant that just about anyone could figure out what he'd really meant. There was no way he'd be able to play that off as meaning something else. What had he been thinking - she was his cousin, not someone that he could ogle in public. Maybe if he apologized right now then he'd get off with just being a-
"Well if that's what you want to do. Just make sure that you two bring something to drink up with you, since we don't want the smell travelling downstairs while you... you know." His Dad's words made Dan freeze, his head ratcheting in the man's direction as his eyes almost bug out of his head. No, he couldn't have heard that right. His father hadn't just given him permission to... to...
"Alright, let's go then little man. Maybe if I'm lucky I'll be able to get just a little bit more protein out of you today." Before he could even ask the question now burning in his mind, Laura had slid her hands beneath his armpits and plucked him out of his seat. His cousin smiled naughtily as she pulled him against her, the girl's heavy breasts pressing into his stomach as she made for the stairs. "What...uh, what's going on here?" He murmured softly, a sudden jolt running through his head as soon as the words left his lips. However, once the pain had faded he knew.
In this world, boys possessed a special kind of protein inside their body which could induce puberty when combined with several other chemicals. Girls lacked this key protein, so around the time that they start to experience their changes, they pair off with a boy in order to ensure that they have a steady supply of it. The chemical is transferred via the girls sucking the boys off, so oral sex had become a natural part of maturity for both sexes. Once the boy in the pair started puberty themselves, their supply of this protein would slowly be converted by newly available chemicals for their own growth, thereby normalizing the content of their semen. However, every boy had a different amount of the chemical contained inside them; in some cases there would be enough for both the boy and the girl to grow to average height, however in other cases it was possible for the girl to suck so much out of the boy that she'd grow much larger than her counterpart (boys can obviously refuse to pair and keep the protein for themselves as well). This seemed to be the case with him and Laura, with the girl pairing off with him some time after she'd turned 11 years old. They'd spent an unbelievable amount of time in bed together, the young girl eagerly bringing him to orgasm again and again. Her consistent efforts had paid dividends, with her body ballooning far larger than what one normally expected from a girl that was 14 and was still growing a little even now, his well of protein not completely dried up just yet.
By the time he was able to rationalize everything that he just learned Laura was setting him down on her large bed, her door already closed behind them as she set to work on his pants. She disposed of the pajamas like an expert, swiftly pulling her own shirt over her head and tossing it aside as well; Dan's breath caught in his throat. The bra that encircled his cousin's tits might be described as... just a little too tight, or more accurately almost a size too small, the bright blue C-cup brassiere on its last legs. Her smile became wicked as she agonizingly teased the waistband of his underwear, slowly pulling them down his legs.
"I know that I'll need a new bra sooooon," she moaned lightly, "but I wanted to make sure that I'd fit into it just a liiiittle bit better before I go shopping. Do you think that you could help me with that, Dan?" His underwear were around his ankles now, his dick standing at attention in the pleasantly warm air; all the young man was able to manage was a slight nod in the affirmative, his hormones unable to resist the kind of raw stimulation that he was receiving. Laura looked almost overjoyed, her hot breath washing over him as she leans in closer. "I knew that I could count on you, little man."
She slowly and carefully wrapped one of her long-fingered hands around his penis, pumping it forcefully until he began to pant, his skin clammy to the touch. Then came the real kicker: after a few moments of preparation, she shoved his dick right between her boobs, sending an almost unreal level of pleasure rushing through his body. He'd always been a little larger than average downstairs, but Laura's chest was so large that his head barely managed to poke through on the other side; still, that was enough for her to take him into her hot mouth as she rubbed her sizable assets up and down his length, giving him the best (and only) titjob that he'd ever remembered receiving. Dan didn't last long under those circumstances, his body stiffening as he poured what felt like buckets of cum down his cousin's throat, the girl easily swallowing every last drop that he had and even attempting to milk him for more. It was during this intense mouthing session that he first noticed the change.
First he felt Laura's lips seem to surround his cock that much more easily, then the hands on his thighs inching up just a tiny bit further. Finally, as the bed started to shift ever so slightly more towards her, Dan was forced to confront the fact that his cousin was growing again. This spurt was far more minor than the first one, maybe an inch or two in total, but still produced a number of changes to the girl's body in the process; her arms and legs were longer and sportier, her ass rounder, and even her face was that much more mature than it had been before their 'session'. Still, the greatest growth by far was on her chest, Laura's tits burgeoning bigger and bigger until finally... *snap* her bra gave up the ghost and split right in half, exposing all of her big big breasts to view. And still they grew, forcibly pulling his dick from her mouth and completely surrounding the sex organ with their heaving mass, his cousin staring triumphantly down at him from above.
"It looks like I might be just a little too big for you now, little boy. In fact, I think even a D-cup bra might have some trouble holding these girls back. Whatever are we going to do about that...?"   indicates the next chapter needs to be written. |
