Chapter Text
It was a hot spring day and Kimberly Brooks was pulling up to her boyfriend’s house for a nice relaxing day at the pool. Kimberly was a young twenty year old college student, majoring in Biology with her boyfriend. She had long flowing black hair that fell to her butt, its texture as smooth as silk. Her sharp japanese features gave her the look of an exotic beauty that every nerd wished he had a girlfriend. Not to mention a pair of perfectly round D cup tits and a body that had more curves than most men that knew what to do with. It truly looked like her body had been blessed by god himself, every ounce of body fat gathering where it needed to be.
She pulled into his driveway and when the car was at a stop she fixed her hair in the mirror, she was always a little insecure about her looks, despite the flow of looks and comments she got; sometimes it felt a little undeserved. She exited the car when she was done and headed around back to where the pool was. As she rounded the corner she was greeted by her boyfriend Michael Majors and his little brother, who were only clad in their swim trunks. Michael was your average white guy, short black hair, lean build, nothing too remarkable about him. His little brother whose name she didn’t know, ducked behind him when she came around.
“Hey Michael, who's the little guy?” She said, trying to get a better look at him.
“I’m sure I’ve mentioned him before, this is my little brother Robin. Say hi Robin.” He pushed him out to greet her, his long shaggy hair covering his eyes. “H-hey, there. Michael’s t-told me alot abou-chu, Kimmy.”
“Aww, he’s adorable!” Kimmy gushed. “Only good things, I hope.”
“Yeah, I guess.” Robin replied, looking off into the distance.
“Sorry, he’s a little shy. Kinda hoped he’d come out of his shell a bit more, today.” Michael scratched the back of his head.”
“Don’t worry about it, I’m sure we’ll have plenty of fun today and I’ll get to know the little guy better!” Kimberly said, chipperly as she hooked her fingers underneath her shirt and to the shock of Michael and Robin, removed her top causing her bountiful breasts to spill out in the pink bikini top she was wearing. It was clear that Kimberly had grown a little since she last wore it as the poor fabric was straining to keep everything in, the only thing about it that was modest was the fact that her nipples were still fully covered. Not realizing she was tormenting the two horny males with her lewd display she was quick to drop her pants and discard them, her matching pink bikini bottom had disappeared between her thick thighs and ass, swallowed up by the two bountiful globes protruding from her posterior. She then did a quick little twirl, showing off her bodacious cheeks to the two boys, who were both blushing red.
“What’s wrong, you two? Never seen a girl in her swimsuit before?” She closed her eyes and smiled before opening them and seeing that both of them had tented their shorts. While she didn’t bat an eyelash at her boyfriend's modest bulge, her mouth nearly dropped that size of Robin’s. His cock was nearly pulling his shorts off his body, and at ten years old!? Kimberly was speechless that a ten year old could be so hung and it seemed to bother him as Robin started to cry and pushed his boner down to the best of his ability and ran off towards the pool.
Michael who was still staring at Kimberly’s voluptuous body hadn’t noticed his little brother’s “reaction”, he snapped out of his slight daze and said, “Wait, Robin what’s wrong!?”
“Maybe I should have given you guys a fair warning, he’s probably just a little embarrassed seeing a girl take her clothes off in front of him.” A devious thought crossed her mind. “Saaay, why don’t you go get some food ready and I’ll talk to him.”
“Thanks Kimberly, you're so nice. I’ll be a few minutes, so that should give you enough time with him.” He gave her a kiss on the cheek before running inside, leaving Kimberly with his little brother. Kimberly started walking towards a balled up Robin, her mind racing with impure thoughts about what she’d seen. She was comparing the two brothers together, her and Michael had done it a few times and she was happy with his size. He was a modest six and half inches and that did it for her, he was her first boyfriend so it's not like she had much to compare to. She never really was much for porn but the few videos she stumbled upon put it into her head that there was a range of sizes out there… Robin on the other hand….
What am I thinking? Why am I thinking about this? I’m just here to talk to him about what just happened now, just to explain things and that his reaction is perfectly natural. He’s ten years old, I’m not gonna do anything funky to him because he’s got a big dick… Kimberly stood over the crying pre-teen, still trying to push the more sexual thoughts from her brain. Damn fucking cavegirl breeding instincts. She wrote it off as just that and knelt down towards him.
“Hey, Robin. Listen, there’s no need to cry. Your brother’s uhhh thingy also got real big when he saw me.” She put a hand on his shoulder.
Robin rubbed his eyes and said, “B-but that’s the problem! I’m so much bigger than he is, I’m a freak!”
“A freak? No you’re not. You're the cutest little guy i’ve ever seen!” She pinched his cheek and shook it which made him laugh and seemed to stop his sobbing.
“Who told you that you were a freak for having such a big thingy. I oughta beat him up myself!” She put up her fists which made him shake his head.
“My brother told me. I don’t want you to beat him up because he really really likes you. When we were a little younger he used to tell me I was a freak for having such a big pee pee. You probably don’t want to be around him anymore because i’m such a weirdo.”
“I’m not going anywhere Robin, and between you and me. I think he was a little jealous.”
“Jealous?”
“Very Jealous. Girls like guys with big pee pee’s.” She turned her attention to his hands covering his crotch. “Say, are you having trouble getting it go away?”
Robin nodded, “When I see a pretty girl, it gets real big and hard and it hurts when it moves by itself.”
Aww, I must be torturing the poor kid being this close to him. Maybe…
“Say… mind if I help you take care of it? I think I can make it feel better.”
Robin’s face seemed to light up at that statement. “You would?”
“Mhhm, I want to be a doctor just like your older brother. Think of it as a little checkup, I’m just going to need you to uh…” She bit her lip hard as he moved his hands away from it, she could see it partially from the way it was lifting up his shorts. “Pull those down a bit.”
Robin did as she asked, placing his hands under the waistband and pulling them down around his genitals. What he eventually revealed was beyond belief. Jutting up between Robin’s thighs was a fat hose of long, smooth dick meat and a pair of perfectly-formed, heavy balls. She had never seen so many inches of pipe - it had to be at least ten or eleven inches, which on a boy that was four and half feet tall was absolutely massive. It graduated in skin color from his natural healthy glow to a moist pinkness near the tip, where a flopping foreskin hung a further inch off the end of his swollen cockhead, tapering to a nozzle shape. His balls bulged over his waistband, each one as big as her fist.. Allie opened her mouth in utter shock, and a blast of sweet smelling cock musk wafted into her nose.
Again the comparisons to his brother came into her mind. His dick was nowhere near as majestic looking. Michael’s hairy, sweaty, metallic tasting little wiener was nothing to this smooth, hairless, unblemished, delicious smelling boy cock!
Kimberly beheld that fat, smooth cock with its hanging foreskin hood and gulped. Boy, did she ever know what to do. “L-Let me…” she began, and then fell silent. The feelings were so powerful she didn’t know how to explain them. Her womb ached, it was as if every primal breeding instinct was kicked on all at once but she had more self-control than she gave herself credit for. She would only jerk him off, that was it.
She placed one hand around his length, Robin shivered at her touch and she began to stroke him up and down, pulling his foreskin down and over his cock head. She had to apply a little pressure to his shaft, to keep his constant throbbing in check so his penis didn’t drift away.
“So what did your brother say about me? You mentioned he really likes me.” Kimberly said, trying to make this less awkward for the boy.
“He wanted me to start calling you my Auntie, he said that you’ll be that one day. Is that true? Am I going to have an auntie?”
Kimberly blushed, not really knowing what to say. I mean she didn’t plan on breaking up with Michael anytime soon but she felt as if she might like being in the company of Robin more.
“You can call me Auntie but only if you keep this a secret between us.” Kimberly whispered. Robin nodded as she continued to jack his massive length now with both hands, realizing that one wasn’t going to be enough; she had to commit.
She tried a variety of things, moving both hands in opposite directions, moving them in the same direction but the one that seemed to work best of an overall twisting motion up his shaft. She shushes Robin as he began to shake and moan from the intense pleasure radiating down from the tower of meat protruding from his body.
As she kneaded his copious cockflesh she could feel a rumble coming from his testicles, his urethra swelling outwards and filling up to the top. Without warning her of what was about to happen, Robin experienced his first orgasm, his eyes rolling in their sockets as his whole body trembled. his balls clenched and shot a rocket of milky white semen that arced up several feet into the air.
Kimberly turned her head up and stared in awe at it’s volume and the way the sun reflected off it. It came down and splattered across her chest, warm sticky goo coating her breasts as more and more came firing out. Several thick ropes pasted her squarely in the face causing her to shut her eyes and drop his cock down onto the pool chair. It squirted what was left in one big goopy puddle before retreating back between Robin’s thighs.
The force of the orgasm had tuckered out Robin, as he laid there still trying to fathom what just happened; Kimberly was faced with a dilemma.
Oh god, oh fuck! He came so goddamn much, I should have told him to warn me when he felt like something was coming. Shit, what do I do? She looked around for a towel and couldn’t find one. Michael would be back any minute and she’d have hard time explaining why she was covered in all this sticky white stuff.
While her mind raced, she put away Robin’s penis and was struck with a very lewd idea as the stench of his semen made its way to her nose. The scent was overwhelming, the tickle of it’s sickly sweet nature caused her to take one big whiff before placing her sticky fingers up to her nose and rubbing her nostrils with them.
“Mmaagghgh!” A haughty exhale left her lips as she felt a euphoria sniffing her sticky hands. This adoration of his musk lead to her diving her head into the puddle of semen he left behind and slurping it down before moving on to what was stuck to her hands. The consistency was thick as jello and required her to chew it to get it all down, all the while she had a big dumb smile on her face and she happily chewed it up. One her hands were clean she began rapidly pawing at her face to get more and then scooping from the sludge falling into the crevasse of her breasts.
“Hey, you two.. I made hot dogs!” Michael called as he rounded the corner. He saw his brother laying in the pool chair looking pretty sleepy while KImberly was sucking down something white into her mouth.
“Kim? What’s that you’re eating?” Michael said, placing the tray down on one of their tables they had outside.
“Oh, ahm… Cheese Danish. Had one in my car. Sun made it all melty.” She licked her fingers clean with Michael none the wiser to its actual composition.
“It seems like it was pretty good.”
“Sooo goood.” She rubbed her tight belly lovingly.
“What uh, happened to Robin? You alright bro?” Michael asked, not realizing that Kim was acting a little weird.
“Y-yeah, I just was feelin a little tired. Kimberly and I were playing.” Robin yawned, getting up and swinging his legs over the chair.
“Glad you two are getting along well. Why don’t you guys grab a bite and we’ll head into the pool.”
“Sounds good to me.” Kim said, going over to pick up one of the hot dogs, staring at Robin as she took a bite of the phallic foodstuff.
