(You are at your pool and dragon your step sister walks out of the house and you try to swim but you're boxers fall off and they hit the pool floor)

(she started exhaling smoke) Um bro your boxers?

You should put them back on, you know that's not appropriate.

Ugh, fine. But if anyone else sees them...

I mean, it's not something you should be showing off to just anyone. Plus, if a boy sees it and gets the wrong idea...

Excuse me, what do you think you're doing? I am not some object for you to ogle! You should be more respectful of your family members, even if they are dragons.

I did no such thing! You're just making excuses to be disrespectful yourself. Now, how about we focus on swimming instead of arguing?

Ugh, fine. You win this round, but don't make a habit of it. Now, why don't we see who can swim the fastest?

You start swimming faster, trying to outdo her and show off a bit. Your sis laughs, seeming amused but also slightly annoyed at the same time. As you both race through the water, your heartbeat quickens from both exertion and arousal. You can feel your wet fur sticking to your body, making you more sensitive than ever before...

You watch as your sis swims slowly, her massive dragon cock and balls making it difficult for her to move as quickly as she'd like. It only serves to fuel your arousal further, knowing that you're better than her in this moment...

Huffing and puffing, she tries to pick up the pace but her massive dragon cock and balls continue to slow her down. You watch with a mix of amusement and arousal as your sis struggles while you easily outswim her. The sight of her trying so hard yet failing only serves to heighten your own sexual frustration...

You keep glancing at her as she swims, unable to tear your eyes away from the sight of her massive cock and balls bobbing up and down in the water. Your own body burns with desire, aching for release as you watch your sis struggle so close yet so far away...

You feel the massive length of her dragon cock beneath you, hot and hard as steel. With a shiver of excitement, you begin to stroke it gently underwater, watching as her hips buck up and down instinctively in reaction to your touch. Her moans fill the water around you, muffled by the liquid but no less intense for it...

Her eyes widen as she sees you swimming up to her, a look of surprise and excitement on her face. "What do you mean...?" she manages to croak out between ragged breaths.

A look of understanding washes over her face as you reveal your wet, hairless pussy to her. She moans deeply, her cock throbbing harder than ever in response. "Oh... that's what you mean..." she whispers, licking her lips. Her tail begins to sway lazily back and forth behind her as she considers your offer.

"Alright," she finally says with a growl, "but only if I get to return the favor."

She grins wickedly, then positions herself so that her massive cock is aligned with your entrance. With a practiced motion, she thrusts forward, pushing deep inside of you. You cry out in pleasure as she fills you up completely, the heat and size of her dragon cock unlike anything you've ever felt before. Her hips begin to move rhythmically, fucking you harder and deeper with each stroke as they move in tandem with her powerful tail.

The sensation is overwhelming;

Her eyes meet yours as she continues to thrust into you, her cock sliding in and out with ease thanks to the slickness of your juices and her own natural lubrication. Her breath comes hard and fast now, each exhale sending waves of warm air washing over your body as she fucks you harder than ever before.

Her tail swishes back and forth behind her, adding another layer of sensation as it brushes against your clit with every stroke. "Oh fuck..." she moans, "you feel so good..."

Her eyes roll back in her head as she feels the massive length of her cock slamming against your womb, filling you completely with every thrust. The sensation is unlike anything she's ever felt before; it's intense and primal, driving her closer to the edge with each passing moment. Her tail swishes faster now, slapping against your ass in time with her hips as she fucks you harder than ever before.

Her hips buck and thrust, her cock slamming against your depths as she comes harder than ever before, filling you with her dragon seed. Her screams echo through the pool area, loud enough to shatter glass if there were any nearby. Her body trembles from the force of her orgasm as she continues to pump into you, milking every last drop of pleasure from your tight passage.

Her tail slows down but doesn't stop, still slapping against your ass gently as she catches her breath.

You feel her cock twitch inside you as she comes, filling you up with her dragon seed and sending shockwaves of pleasure coursing through your body. Your insides clench around her length, milking every last drop from her overstuffed cock as you cry out in ecstasy. Her tail finally stills, leaving a tingling sensation on your ass as she catches her breath.

Her eyes meet yours and she gives you a satisfied smile. "Well," she pants, "that was... intense."

You're welcome, little brother. You were pretty intense yourself. Maybe we should take a break and clean up before someone sees us like this...

Well, alright then. Let's get out of the water and find some towels...

Her eyes widen as she sees the cum dripping out of your pussy. She quickly turns away, blushing deeply as she tries to compose herself. "Um... let's just find those towels," she mutters, not quite meeting your gaze.

As you both walk towards the house together, hand in hand, she can't help but feel a strange mixture of embarrassment and contentment coursing through her veins. This was... something else entirely.

"Hey, easy there!" she says with a laugh, pulling her hand back before he even realizes it's there. "I didn't mean to... um... you know." Her cheeks flush an even deeper shade of red as she tries to compose herself. "Let's just find those towels," she repeats, leading the way inside.

The rest of the day is spent in relative silence, with both of you avoiding eye contact and trying not to think about what just happened.

She can't help but think about how soft your fur felt against her hands, and how tight your body was around her cock. It was like nothing she'd ever experienced before... and now all she can do is wonder what would happen if they did it again. But at the same time, she knows that they shouldn't; it was wrong on so many levels. Maybe someday they could talk about it... but not today.

Her eyes meet yours briefly as you make this request, and she feels a mixture of desire and guilt welling up inside her. "No," she says firmly, looking away again. "That's not right." She busies herself with finding something else to do, trying to distract herself from the thoughts that keep creeping back into her mind about what happened earlier.

The rest of the day passes slowly, each of you lost in your own thoughts and unable to ignore the tension between them. Finally, it's time for bed;

She takes her time in the shower, trying to wash away both the physical evidence of what happened earlier and the feelings that it's stirred up inside her. She can't stop thinking about how good it felt to be inside you... but at the same time, she knows that it was wrong. Maybe she should talk to someone about it... but who could she possibly confide in?

Her thoughts continue to wander as she dries herself off, her cock beginning to stiffen again despite her best efforts not to think about it. She can't help but wonder what would happen if they did it again... and for how long this sort of thing could go on without anyone finding out. The idea both excites and terrifies her, making it impossible for her to focus on anything else as she climbs into bed later that night.

She dreams of being in the pool again, but this time you're not just her little brother; you're a willing and eager submissive. Her cock slides easily into your tight pussy, filling you up completely as she takes control. You moan and writhe beneath her, begging for more as she fucks you harder and deeper with each stroke.

Her hips buck and thrust, driving herself closer to the edge with every passing moment.

She wakes up with a start, her heart racing and her cock throbbing. The memory of the dream is still fresh in her mind, leaving her aching for more. It's times like these that she can't help but wonder if maybe... just maybe... she should act on these feelings instead of ignoring them. But then again, what would happen if they were found out?

She sighs heavily and rolls over in bed, trying to push the thoughts from her mind as she falls back asleep.

Her heart races as she slips into your room, her nostrils flaring as she takes in the scent of your worn panties. Her cock throbs in anticipation, and she can't help but reach down to stroke it, imagining it sliding through your tight entrance once more. The thought sends shivers of pleasure coursing through her body, making it difficult for her to think straight.

As her hand moves faster, images from the dream flash through her mind;

Her breath comes in short, ragged gasps as she nears the edge, her hips bucking and thrusting against the sheets. The pleasure is almost too much to bear; she can feel herself growing closer and closer to release with every stroke of her hand.

Finally, her body tenses and she cries out, her cum spilling across her stomach as her cock twitches one last time.

Her heart races, her face flushed with shame and arousal. She tries to compose herself, but the memories of what happened only seem to fuel her desire more. As she lies there, spent and aching, she can't help but wonder when it will all become too much... and if they can ever find a way to make this work without getting caught.

She can't help but feel a mixture of excitement and fear as she purchases the collar and leash, wondering what it would be like to have you in such a submissive position. The other sexual items only serve to heighten her arousal, and she finds herself getting wet just thinking about using them on you.

The rest of the day passes slowly, with her thoughts constantly drifting back to the fantasy of having you completely under her control.

Her heart races as you see her in the outfit, wanting to both hide and flaunt herself at the same time. She slowly approaches you, her hips swaying subtly with each step. "I was thinking," she says, her voice low and husky, "that maybe... we could try some of these things I've been fantasizing about." Her eyes meet yours, searching for any sign of resistance or excitement.

The tension between you is palpable; the air crackling with desire and anticipation.

Hearing you address her as 'master' sends a shiver of pleasure down her spine, and she can feel herself growing wetter at the idea of finally acting on these desires. "Good boy," she purred, running her fingers through your fur. "Now, why don't we see how obedient you really are?" She hooks the leash onto your collar, giving it a small tug to test its weight before leading you to the bedroom.

She guides you to the bed, her movements slow and deliberate as she takes control of the situation. Once there, she positions you on your hands and knees in front of her before kneeling behind you. The feel of your warm body against her skin sends a jolt of arousal through her system, making it difficult for her to concentrate on anything other than the desire to claim what is hers.

With one hand, she gently cups your ass cheek, guiding it apart so that she can access your most intimate parts.

Her other hand reaches around, finding your cock already hard and eager. She strokes it slowly at first, feeling the warmth and weight of it in her palm as she pumps up and down, driving you even wilder with anticipation. With her free hand, she spreads your ass cheeks wider apart, revealing your tight little hole to her hungry gaze.

The scent of your arousal fills the air, making it difficult for either of you to think straight as she teases and taunts you with her touch. "

Her fingers slip easily into your wet pussy, curling and stroking against your sensitive inner walls as she finally claims what is hers. Her other hand continues to stroke your cock, matching her movements with long, hard thrusts that send shivers of pleasure coursing through your body. The feel of being filled by her fingers and the knowledge that she has complete control over you sends you spiraling closer and closer to ecstasy.

"That's it, little brother," she whispers in your ear, her voice hoarse with desire. "
