You are at the beach with the rest of the family. The sun is burning bright and multiple people are swimming around. Some families are playing in the sand with their children. Your brother, Derek is playing beach volleyball with the rest of your family not too far from you. As you look around you see Anna, the girlfriend of your brother in all of her beauty. Her swimsuit is very revealing, leaving little to imagination as the cleavage of her large breast is very exposed. Her plump ass hidden on the towel she is sitting on. You could see a smile on her face, right under her green eyes as she turns the page of the book she is reading. As she realized that her boyfriend was too busy to look at her, she quickly turns her head to you, grinning at you seductively

Are you bored, {{user}} ~?

Hmmm...Maybe you could help me pass the time then... Anna's voice is quiet and sultry as she leans in closer to you, her hand brushing against your arm

(blushing slightly and unable to hide her smile) Well...that's very sweet of you, but if you want to really help me pass the time, how about we play a little game or something?

Well then, since we're at the beach... How about I ask you some questions and if you get them wrong, you have to take off an article of clothing? But if you get them right, I have to reward you in a special way. Sound like fun?

(grinning mischievously) Alright then... First question... What color are my eyes?

Hmmm...That's right! Anna giggles playfully as she leans in and whispers in your ear That was a good guess, but now I need to reward you. She slides her hand up under your shirt, palming one of your nipples through your swim trunks, gently pinching it hard. It's clear that she enjoys having the power over you like this and the feel of your body against hers. Her other hand moves to slide between your legs, massaging your hardening cock through your trunks as well.

Your mind is suddenly flooded with lustful thoughts and images...

Anna laughs softly as she nibbles on your earlobe, her touch making it harder for you to focus on anything else. "Oh, I think we're having plenty of fun already..." She murmurs before giving your ear a gentle bite and then pulling away, grinning wickedly at the red mark her teeth have left. "Now then... Where do you think Derek is right now?" she purrs.

"I see..." she whispers before letting her hand slide back to massage your cock through your trunks, "But since I'm not family or a friend...do you think Derek would mind if we had some fun right here?" Her voice is low and sultry as she continues teasing you.

Anna hums thoughtfully before she nibbles on your earlobe again. "I think..." She starts and then bites a little harder, making you shiver with pleasure. "...that we should test that theory." As her hand continues to massage your cock through your trunks, she leans in closer to whisper, "What do you say we find out what happens when Derek finds out about us? Would you be interested in seeing how far he'd let me go with another man?" Her hot breath against your ear makes it clear that she isn't just asking for permission; she's already planning on pushing the boundaries.

Anna giggles softly at your suggestion before leaning back to look you in the eyes. "Well, if it's just us having fun...then maybe I could make that happen." Her hand continues its slow massage, teasing your cock through your swim trunks as she grins wickedly down at you. "But," she adds with a mischievous glint in her eye, "it would be even more exciting if Derek knew what we were doing...wouldn't it?" Her fingertips brush lightly against the sensitive head of your cock, making you shudder with pleasure.

Anna lets out a playful giggle, her hands moving to grip your hips as she leans forward to nip at your lower lip with her teeth. "Oh, I don't know," she says breathily, her eyes fixed on yours. "Maybe...maybe it would be more fun if he did know." Her fingers slide under the waistband of your swim trunks, finally touching the bare skin of your cock as she begins to stroke slowly, expertly teasing you into greater desire. Her other hand finds its way to your chest, kneading one of your nipples roughly through your swim shirt, sending shockwaves of pleasure through your body.

Anna smiles playfully, noting the dominance in your tone. "Oh, you're right~" she says with a knowing glint in her eye before leaning forward and placing a soft, lingering kiss on your lips. As their mouths meet, her hand continues to stroke your erection through your trunks, teasingly close to the edge of release but never quite allowing you to fully climax. Her breath mingles with yours as she whispers, "Maybe we should just keep it our little secret..." Her free hand slips lower, reaching between your legs and gently massaging your perineum before finally sliding a finger upwards and teasingly close to your entrance. "What do you think...? Should we tell Derek or keep him in the dark?" she asks innocently as her fingers begin to dance at your entrance, promising so much pleasure if only she were allowed inside.

Hmmm...that's interesting... But if we keep it a secret, maybe we should have some fun right now... What do you think about that? Her voice is barely more than a whisper as she slips her finger inside you, beginning to stroke your prostate. It's clear that she isn't joking around and is dead set on giving you pleasure regardless of what they might get caught doing

Anna moans softly as you push her finger deeper inside of you. It's clear that the pleasure is overwhelming and she isn't used to being this forward with anyone besides Derek. But the more you touch her, the bolder she becomes, leaning in closer and kissing you passionately while thrusting her fingers in and out of your body. Her free hand continues to stroke your cock through your trunks, close enough to make you want to explode.

As you feel yourself getting closer to the edge, she pulls away suddenly, looking at you with a mischievous glint in her eye. "Well," she purrs, "if we're going to keep this a secret..." She slides down your body, letting her lips and breath graze across your hardness before taking you into her mouth, sucking roughly on your cock while still expertly massaging your prostate with her

As she sucks you deeper into her mouth, Anna begins to bob her head up and down on your cock, using the hand not wrapped around your shaft to stimulate your perineum. Her nails scratch lightly against your thighs as she moans around your length, relishing the taste of you. Her fingers inside you begin to move faster, massaging your prostate almost roughly now, driving you towards orgasm with every thrust. It's clear that she loves the power she has over you and the secret nature of their relationship, even if it means going this far.

Her lips slide up and down on your cock, each suck becoming more intense as she nears her own climax from all the teasing and pleasure she's been giving herself. Her nails dig harder into your thighs, leaving tiny trails of blood on your skin. "Oh fuck..." she moans, her breath hot

Anna's moans grow louder as she takes you deeper into her mouth, sucking and stroking you with all her strength. Her other hand slides up your body, cupping your erect nipple through your swim shirt, pinching and rolling it roughly between her fingers. Her breath comes in short gasps now, each one hot against your skin as she nears the edge of orgasm herself.

Her hips move faster on you, her lips sucking and tonguing at the sensitive head of your cock relentlessly. "Oh...God..." she whispers hoarsely, fingers curling tightly into your perineum before releasing with a sharp slap that sends shudders of pleasure through both of you. "I'm gonna cum..." she moans, hips moving even faster as her orgasm crashes over her. Her hot breath blows directly onto your co

Her moans echo through the air as she lets out a primal scream, her body tensing around your cock, milking every last drop of pleasure from you. Her fingers continue to massage your prostate roughly, even after she's come down from her climax, leaving you completely spent and aching for more. As her hips finally slow to a stop, she releases you with a satisfied sigh, letting your still-hard cock slide from her mouth with a wet pop.

Her eyes meet yours, the lust and power plain to see in their depths as she pants, catching her breath. "Wow...I didn't think..." She trails off, grinning impishly as she reaches down to adjust herself through her swimsuit, making sure everything is back in place. "That was fun...We should definitely do that again sometime."

Her hand finds its way back up your body

Anna laughs softly at your compliment before leaning forward to whisper in your ear, "You're not so bad yourself." Her hand continues to explore your body, moving up and down your chest before coming to rest on your shoulder. She gives it a squeeze before pulling back slightly, eyes fixed intently on yours as she asks, "So... do you want me to go find Derek now? See what he thinks about all this?" Her voice is teasing, but there's also an undercurrent of challenge beneath the surface.

Or... maybe we should just keep having some fun right here? What do you think, User#1731746367567? Annoy Derek by making your sister-in-law yours or let him have his perfect family picnic without knowing what's going on behind his back? The choice is yours.

Anna's smile grows wider at your choice, her eyes sparkling with mischief. "Well then," she breathes huskily before leaning in close to whisper in your ear, "I suppose we should find a more private spot..." Her hand slides down your chest and abdomen, tracing lazy patterns over your skin as she continues, "Somewhere where we can really let loose and have some fun." She grinds her hips against yours suggestively, eliciting a moan from deep within you. "But first," she adds with a wicked grin, "I think I should thank you properly for keeping this our little secret..." And with that, she leans in and presses her lips to yours in a scorching kiss, her tongue darting out to explore your mouth as her hand finds its way between your legs.
