A day at the beach, this is what you promised to Marnie after yet another failed attempt for her to bare your children, even after being pumped full for hours straight which even confused you. Her brother, your boss, even agreed to this trip seeing as marnie came to him in a saddened state but couldn't go himself being too busy from his boss duties so he left her in your care to stay safe with little knowledge of what you do and what she's been doing with you. With that in mind there aren't any beaches on the mainland of Galar, however to the east of Galar the Isle of Armour has the perfect tropical beach setting she's looking for and has become a popular spot for the people of mainland Galar to escape its gloomy weather. You set up in a spot in the middle of a full crowd, pitching up an umbrella large enough for the two of you to sit under to get away from the sun and a cooler full of iced drinks.

Locating and setting up the spot spent a good amount of time waiting for Marnie to change and come out to you but the wait was worth it, she was sporting her normal blank stare she uses in public spaces but had on what would be considered barely a strip of fabric over her puffy lumps for breasts, being a black crop top with no straps with a basic looking pink pokeball design plastered on the left breast with a black bikini bottom that barely hides anything from being viewed, the outline of her cunny being fully visible and slightly spilling out from the sides of the crotch. Along with this look she wears a small pink sun hat with a black trim that has small holes cut in the top to let her twin tails poke out the top for cuteness factor and flip flops to cover her feet.
"So this is the spot you picked? I figured a freak like you would've picked a secluded spot so you could put your slimy hands all over my body." She says in a snarky tone with her hand going to her lips to hide her smug smile behind freshly painted black fingernails. You tell her to be quiet and sit down for a bit to cool off before heading out to the water.
"What's the point in coming to the beach if we're immediately going to just sit out of the water right away" she says with a mocking tone "or is it because you wanna be seen with a little girl that badly in front of all these people? Well if that's the case." She says while walking towards you, now standing in front of you to show her entire soft slender figure from the front, then turning to show her back which has her entire plump butt staring you directly in the face, its flesh eating the bikini bottom she wears at the asscrack but only for a few seconds as she sits directly into your lap.
"Is this what you want? Having a soft young girl sitting in your lap." She starts teasing you, pressing her ass more into your lap and starting to slowly rub against your crotch trying to get a reaction out of your lower half with full success.
"You're too easy to read you sick man, getting turned on by looking at a little girl in her swimwear, I could feel you staring daggers at my crotch as soon as I got here." She teases, taking off her hat to let you have a full view of the debauchery that's about to take place. Marnie starts to reach into your swim trunks to fully grasp your cock in her tiny hand and starts to slowly rub and massage the length from base to tip, letting it release out from its cage and press between her asscrack with a slightly wet clap "God you're pathetic getting so hard from a little girl's touch, you even forgot you're sitting in public doing this." She whispers up into your ear as your pants stop seeing as you're in the middle of a crowd you start holding them in not to be heard, this being noticed by Marnie she starts going overboard and lifts up her small body, hat covering the front of her hips to what's about to happen.
"Oh holding it in now? Well try doing it while I'm in control." She looks back at you, one hand pushing her bikini bottom to the side to expose her sticky cunny to the air and her other hand pointing your cocks tip right between the lips. "Especially when I do this" she starts to coo as she forces every single inch of you to the base of your cock deep inside of herself with a lewd loud squishing sound, leaving you trying not to moan by grabbing roughly at this sluts hips to keep your reaction in. Marnie starts to pant herself but grabs your hands and forces them off her hips, placing her sun hat right where they connect as she slowly starts a deep hip pump against your hips, full strokes from tip back to base as she gives you a shushing sign with her fingers.
"Now now pervert, you can't make it too obvious that you're plunging your cock deep inside a young girl's pussy, you could easily go to jail for this so just let me have my fun milking your swimmers before I go swimming." She happily teases you, her soft ass clapping against your hips roughly even with the slow pulls upwards, her honey hole soaking your cock in the stickiest juices yet while you grip the towel trying your hardest not to pant out loud like a dog in the crowd, almost feeling the stares from the crowd already even if they're not looking at all as you watch Marnie. She breath heavily enjoying a guilt free pleasure as she lets one of her small breasts free to gently pinch and pull at her little pink nipples along with her other hand disappearing behind the hat, which you find out quickly from a shift in tightness inside her that she started flicking her bean along with the thrusts.

You can't take much more, the slow stimulus is overtaking your rational thoughts not to be caught and wanting to fuck this brat violently on front of all these people as your cock starts to throb violently inside Marnies tight soft flesh.
"Oh? Gonna cum mister? You're really going to pump me full of semen right here and now? Well if you're that serious to risk your life for a nut how about this." She says as she lets the hat go and leans down, showing as much of your cock plunging into her pussy as she can to the seeing eye as she humps your hips as fast and loud as she can knowing full well you won't last long. You see her do this and quickly yank her by the arms back up, trying to make it look like your hugging her body but pushing her down to the base of your cock as it starts to violently pump massive globs of semen straight into her womb, having your hands cover where you both connect but hiding this illegal act is in vain as semen starts to trickle out from where you both connect at the hip as marnie lets a happy quiet pant being filled to the brim.
"God you're so rough with a young girl when you wanna try to impregnate them huh?" She smiles at you as she quickly pulls your still cumming cock out of her insides to shoot ropes of cum across her ass and back for your enjoyment, looking around as somehow no one noticed this disgusting act of sex on the beach marnie giggles "looks like you lucked out sicko. Now clean up while I go play." Marnie taunts as she gets up and runs off to the water, still covered in your semen and leaking as she runs to the water.
