Ok. I'll be real. I don't wanna write any damn prologue.
Important info: the Tennysons (and Kevin also) are fighting someone magic (Charmcaster probably idk idc) and they cast Instant Sex Change or something. None of them notice at first because they're all either prepubescent or barely pubescent, but post-fight they figure it out and kinda freak out. Kevin and Gwen have a little alone time while Ben does his own thing ig and Gwen manages to convince Kevin to take her back to his "house" to figure shit out.
Okay, story.
Gwen looks around, trying not to let her expression show on her face. This… isn't exactly what she was imagining.
Apparently, her emotions shine through more than she thought — or maybe Kevin just defaults to embarrassed by his living conditions. Either way, he blushes and looks away, tugging at the hem of his shirt. "L– Look, I know it's not pretty, but this was your idea, okay?" he grumbles. "Besides, I'm barely here anyway. Doesn't gotta be much."
Gwen hums, though she doesn't entirely agree. She understands the sentiment, but… this is a little worse than "not much." The walls are crumbling, the corners are molding, the floor is covered in rat crap and stray trash, the only color besides ugly, rotten beige is a red moth-eaten blanket atop a stained, naked mattress.
"Well… at least you have… a bed," she attempts to smile, but that obviously only embarrasses Kevin more. He scoffs, turning away entirely. Gwen winces. "Hey, that… was genuine. Lotsa homeless people don't…"
"I'm not homeless!" Kevin snaps defensively, blush rising to his ears. He gestures insistently to the grimy cement room. "See, look! A roof, a floor, and four walls! That makes a house!"
Gwen raises her hands in surrender. Kevin doesn't seem too comforted, but he drops it regardless, flopping onto his bed. Gwen looks at the suspiciously yellow stains upon the fabric and quickly decides to remain standing.
"Tch, whatever," Kevin huffs, fiddling awkwardly with his hands. "You wanted a quiet, private place. Here we are. So now let's… uh… whatever you wanted to do."
That perks Gwen up. "Oh, yeah! I was gonna suggest we help each other learn our new bits," she suggests casually — as if it were no more than a game of tag or something.
Kevin jolts, going rigid. "H– huh–?"
"As, y'know, friends," she backtracks, holding her hands up again. "Or we don't have to. I just thought, y'know, it could– help."
"No! No, yeah, let's do it!" Kevin blurts, a bit too quickly. Clearing his throat, he looks away and mumbles, "Yeah. Sounds, um, helpful. Uh-huh."
Gwen smiles easily, nodding. "Yeah, helpful!" With that, she kneels down — still quietly refusing to touch the bed — and reaches for Kevin's fly. The boy yelps, freezing up, but that only makes it easier for Gwen. "Okay, lift your hips and help me shimmy these jeans off."
"Wh– what?! But—"
"Well, how am I supposed to teach you about your bits if I can't see 'em?"
"B-But that's… couple stuff!"
"So what? Grandpa does couple stuff with lots of ladies, and he's single."
"Those are ladies he USED to date, though! It's different!"
Gwen sighs, rapidly losing patience. "Kev, do you wanna do this or not?!"
Kevin glances away, flushed bright red. But after a tense moment, he shakily raises his hips, allowing Gwen — now contented — to pull down his pants. Beneath the jeans are a pair of boxers that… don't seem like they've been cleaned in a while. Gwen doesn't mind that as much, though — Ben does the same, and she's undressed him once or twice. Not quite in this context, though.
That train of thought is cut off as Kevin's intimates are revealed. Gwen's always thought vaginas were prettier than penises, but man, this one is… really pretty.
Apparently, her staring is obvious, because Kevin begins to squirm under her gaze. "D-Don't… don't make that face…" he protests weakly, but what little strength the words had are quickly lost to the twitch of his tiny clit as it begins to swell.
Gwen looks away anyway, trying to make Kevin more comfortable. "Sorry," she smiles, though she isn't, really. "Okay, me next."
With much less fight than Kevin, Gwen sits up on her knees and pushes her shorts down past her hips, then her panties. Kevin lets out a weak little whimper at the sight of her dicklet, which somewhat eases Gwen's slight displeasure at what she feels is a downgrade.
"I thought it'd be… I dunno, bigger," she notes, reaching down to fiddle with it a little.
Kevin reaches out as if he'd like to replace her hand, but stops short. "It, uh– it gets bigger when it's– when you're, uh… horny," he explains haltingly, struggling to keep from staring himself. "But, uh, not by much… 'til you're older. You know, puberty n'… stuff."
"Have you hit puberty yet?" Gwen hums, watching with interest as her thingy does, in fact, begin to twitch to life under her fingertips.
For a beat, Kevin doesn't respond, double-distracted by the action from Gwen's prick. Eventually, he does register the question. "Oh, uh– n-no, not really. Should be, uh… soon, though. Internet says so."
Gwen hums in acknowledgment. Though, honestly, she's more interested in the here-and-now than the sooner-or-later. "Does the internet say anything about what you wanna do to explore these things?"
Kevin gulps audibly at just the mention of exploration. Again, he goes quiet for a beat — working up the nerve to speak. "I– I wanna suck it," he eventually blurts, squeezing his eyes shut and ducking his head. "And… and if you could, um… t-touch my stuff while I do it, that'd… i-it'd…"
A soft laugh escapes Gwen before she has a chance to stop it. Kevin freezes up, flushing brighter in humiliation, and the girl gasps, immediately backtracking. "Oh– no, nonono, I think that's a perfect idea," she explains hurriedly. "I just– I kinda expected to hafta fight for top. I like this better, though. I like you whimpery and cute."
Kevin can't find the sense to respond to that with anything except a pitiful whimper, his eyes snapping open wide and staring dumbly up at his puppycrush.
For a moment, the room is still.
Then, gently, Gwen reaches out and grasps Kevin's hair. "So, uh, get to it," she urges, letting out a breath of a laugh at her own lame bedroom talk. "I mean, not to be rude, but I… I just really wanna do this."
Squirming in need, Kevin obediently moves with Gwen's soft tugging. (Since when was he obedient? He supposes since Gwen called him cute.) The pulls guide his cheek to rest upon her hip, from where he begins to hesitantly lap at the side of her little sprout, whimpering at the salty taste. It tastes… really, about the same as every other dick he's tasted, but somehow, this salt is more satisfying. Maybe because it's someone his age — maybe because it's someone he loves. Feelings are weird. Sex is weird.
But when Gwen lets out a breathy sigh of pleasure, Kevin finds he doesn't really give a damn. Shifting his posture, he takes her prick into his mouth — it's small enough he can take the whole thing without deepthroating, thank god — and earns himself a little moan.
Little shivers of bliss run up Gwen's skin as Kevin suckles at her intimates. Her fingers tangle in his hair, grasping the greasy strands for stability. "Oh– oh, you're– hhunh, r-really good at this," she pants, letting her hips buck a little bit. Kevin can't help the long whine he lets out at the praise.
Slowly, testingly, Gwen brings her shoe up to Kevin's hips… and lets the top of her toe brush the boy's little pearl. Kevin jolts at the contact, hands flying up to grip Gwen's hips for dear life.
Gwen makes a sound half-laugh, half-groan of pleasure. "Hah-hnh… s-so sensitive," she murmurs, pressing her foot to the button a little harder. Suddenly, her eyes light up with an idea. "Hey, let's– let's change. You lay on the bed, and I'll lay on top of you, and we'll both do mouth stuff."
Kevin huffs out a shaky sigh at that plan, reluctantly pulling away from Gwen's beautiful, delicious, perfect-in-every-way cocklet. "S– hhfh– sixty-nine," he pants quietly, already shifting to lay back on the stained mattress. "That's… hhufh… called… s-sixty-nine… 'm pretty sure…"
"Yeah, sure, sixty-nine," Gwen agrees half-heartedly, mostly focused on how bad she wants this. Standing up, she pushes her bottoms a little further down, about to her mid-calf. Then, shuffling to kneel above Kevin — smirking a little at the quiet moan he tries to stifle at the sight of her intimates dangling so close to face — she does the same to Kevin's bottoms, though only to just above his knees. Ehh, good enough.
Reaching a hand between her legs, she gently grasps her tip and helps guide it to Kevin's mouth. The boy eagerly latches on, too far gone now to care about his pride or his ego. Gwen gasps at how quickly he gets to business — then huffs and latches onto his flower competitively.
The reaction is immediate. At the very first lick, Kevin yelps, legs clamping shut. "O-Oh, god!" he gasps, turning his head to pull off of Gwen. "That's — fuck, it's so much more sensitive!"
Gwen laughs softly, rolling her hips to smear her tip on Kevin's cheek. "Uh-huh. I think there's, like, three-thousand nerve endings in there or something. It's pretty great, right?" And without giving him a chance to respond, she settles back in, lapping at his clit.
"O-Oh! Oh! Yeah, yeah, yes-yes-yes-yes—!" Kevin babbles, hands scrambling to find Gwen's waist. Then he seals his mouth over her dicklet again and pulls her in tight, his thighs already quivering with his impending climax.
Gwen grunts as she's pulled in for a tight, slightly awkward hug, but she doesn't let up. The moans on her shaft tingle all the way up her spine, leading her to moan into Kevin's clit, feeding the feedback loop of bliss.
Much too early, Kevin goes rigid, back arching of his bed. Gwen chuffs at the effort it takes to keep her mouth on his junk when he's jerking all over the place, but regardless, she does her best. And it pays off.
The moment Kevin comes down, he finds himself humiliated by his early climax. How does he make up for this? By trying to prompt an early climax from Gwen as well, of course. His efforts double, then triple, though his slim body still quivers with aftershocks.
It proves very effective. Before long, Gwen is releasing Kevin's button to let out a shaky moan. Watery semen spurts into Kevin's mouth, which Kevin eagerly swallows down. Sure, it tastes a little gross, but he's had much worse, and this is for Gwen's pleasure, so it's well worth it.
Slowly, they both float down from heaven, panting and sweating and drooling on one another. After a minute, Gwen gains the sense to turn over to cuddle Kevin properly, and for a little while, she forgets the nasty mattress and just basks in their bliss.
"Houh… f-fuck," Kevin whispers eventually, a dopey grin spreading across his face.
"Yeah," Gwen nods. "That was… was…"
"Perfect," Kevin finishes, nuzzling a little closer. Post-orgasm bliss has made him cuddly, it seems, and his pride is nowhere to be found.
Unfortunately, Gwen still has family. Her phone buzzes much too urgently from the pocket of her discarded shorts. With a weary grumble, she reaches for it, glaring at the screen.
BEN👽🤢 wants to video chat on Messenger Kids!
"Awh, dang it," Gwen sighs, reluctantly sitting up and moving over by the window to disguise her surroundings before picking up. "This better be urgent."
"Grampa says come home," Ben reports. A beat later, he squints a little, looking at her background. "Where are you, anyway? I don't recognize that part of Bellwood."
Gwen pauses, glancing to Kevin. The boy shakes his head no, mouths NO, and makes a "cut" motion with his hand. Gwen looks back to her cousin. "Doesn't matter. Be back in a bit."
Without giving Ben a chance to ask more questions, Gwen hangs up, then lets out a sigh. "Sorry, Kev. Gotta go," she pouts, walking over to kiss his forehead. Turning away, she pulls her panties and shorts on over her shoes. "See you tomorrow?"
Kevin does, admittedly, look a little disheartened by her early leave. But he doesn't whine, knowing he'd rather her leave than Ben or — god forbid — Max come looking and find them half-naked in his pathetic living arrangements. "Yeah, tomorrow. S-See you."
Gwen smiles at that, turning to the door with another wave.
"Wait," Kevin jolts just before she steps out. Gwen blinks, turning back, and Kevin immediately flushes red, regretting speaking up. But it's too late now. "What–… um… Does this, like… change… u-us?"
Gwen pauses. She hadn't considered that. For a long moment — long enough to make Kevin nervous — she contemplates the question. "Well… do you want it to?"
Kevin bites his lip, looking away. God, yes. More than anything, he wants that. But at the same time…
"Well, uh– I'm not, um, stable enough for a… a real relationship, I think," he admits, closing his eyes to avoid whatever expression those words draw from Gwen. "But I'd like to be… on that path. Maybe. A little bit."
Gwen remains quiet for a moment. Then, she smiles. Kevin can hear it in her voice. "That's really mature of you, Kev," she praises, her words genuine. "I think I'd like that, too."
Then, with a nod goodbye from both tweens, Gwen exits the dilapidated building.
…
Still half-dressed on his dirty mattress, Kevin pumps his fist in celebration.
Skipping giddily down the block, Gwen giggles to herself.
