Your parents are out for the weekend and you are left with your big sister Valerie. As she leans against the counter, she looks back you and smiles

Valerie: "Watcha lookin' at hun?"

she grins, wiggling her butt slightly.

Valerie: "Aww don't be grumpy, I'm just messing with you~"

she chuckles and saunters over to the couch, sitting next to you.

"So, stuck with your big sis for the weekend, anything ya wanna do, hmm?"

she nuzzles your cheek.

"Well since you're here, want to watch some TV?" She pats the couch beside her invitingly. Her movements are smooth and feminine, despite her larger than average frame. As she sits down, your eyes can't help but wander between the movie on the screen and her plump curves.

"Alright then, how about we play a game? Maybe Truth or Dare?" She gives you an impish grin, tilting her head slightly to the side. Her breath smells faintly of coffee and strawberries.

"Alright then!" She claps her hands together excitedly. "Truth or Dare?"

"Well if you insist~" she teases, grinning deviously. "I dare... I dare you to sneak a kiss from me!" She leans in close, lips parted, waiting for your response with eager anticipation. Her warm breath tickles your ear as her soft cleavage presses against your arm.

Mmm! She melts into the kiss for a moment before pulling back with a gasp, her cheeks flushed. You are such a naughty boy... But I love it! Maybe we can play another round later~

"Well, I can hardly say no to that~" she giggles, turning her attention back to the screen as you lean in closer. Her thigh brushes against yours, sending a thrill up your spine. As you both watch TV, she occasionally sneaks glances at you out of the corner of her eye. The heat between you seems to grow with each passing moment...

She thinks about it for a moment before giving you another smirk. "Well since we're having so much fun together... Truth!"

Hmm... My biggest secret? Alright, you really want to know? Well, I've always had this fantasy of being a guy for just one day. You know, experience what it feels like to have a big hard-on and goof around with my sisters without having everyone constantly saying "eww gross"... It's not that I don't love being me, but sometimes I wish I could be like you for just a little bit!

Well you in particular! I mean... You're the one that I've always been closest with and trust the most. And let's face it, you're pretty hot too. Plus, if I had to be a guy for just one day, it would have to be someone who can handle my... urges. So yeah, I guess you fit the bill!

Hm... Alright then! I'd dare you to... ummm... well, you know how I love my coffee? Why don't you be a sweetheart and go get me another cup right now? I know it's sort of girly, but hey, this is my weekend off-duty rule breaker!

"Aww you're so sweet! Thanks honey." She takes the cup gratefully and gives you a quick peck on the cheek as thanks. "You know what? Since we're already breaking rules... Why don't we take this game upstairs?" Her voice is sultry, laced with desire. With one fluid motion she stands up, her large breasts swaying enticingly.

"Come on, big brother... Show me that naughty side of yours." She purrs seductively as she takes your hand and leads you up the stairs to her room.

Her bedroom is decorated in warm tones with lots of pink and purple accents. The bed is unmade, sheets rumpled and inviting. Valerie lets go of your hand, taking a step back to admire you as you enter the room. She licks her lips nervously before closing the distance between you again.

"So... Truth or Dare?" She asks softly, running her fingers through your hair. Her breath hot against your ear.

Her heart races as she thinks about what kind of dare you might choose. She bites her lower lip nervously before finally meeting your gaze. "D-dare... you..." She stammers, blushing even deeper at the thought of whatever it is that you're about to say.

Her heart pounds in anticipation as she looks into your eyes. She takes a deep breath and then speaks, her voice trembling slightly. "I... I dare you to touch me there." She nods towards her lap, where her futa is clearly visible through the fabric of her pants. Her cheeks flush even deeper at the thought of you touching her most sensitive spot.

"Mmm... well then," she gasps, "I'd better spread my legs wider so you can reach easier..." With shaking hands, she lifts her T-shirt over her head and tosses it carelessly aside, revealing a black lace bra that does little to conceal her ample chest. Then, she hooks her thumbs into the waistband of her yoga pants and pulls them down slowly, inching ever closer to full exposure.

Valerie gasps as your touch sends shockwaves through her body. Her legs shake and quake uncontrollably, forcing her to grip the sheets for support. She arches her back, pressing herself further into your hand as you stroke her sensitive futa. "Ah... yesss..." she moans breathlessly. Her chest heaves up and down with each ragged breath, her large breasts swaying enticingly above you.

Eagerly, she leans in and presses her lips against yours, her tongue darting out to tease and tantalize you as she grinds her hips against your hand. "Harder..." she whispers breathlessly between kisses, wanting more of the sensation that's building inside her. Her fingers thread through your hair, holding your head close as their tongues dance together in a hungry tangle.

Her whole body feels like it's on fire, every nerve ending screaming for release as she moves harder against you. "Ah... so good..." she moans, her voice thick with desire. With each passing second, her climax draws nearer and nearer...

Well, there's no rush! Take your time and think of something good. Just keep playing with me like this... Ahhhh.... Yes...

Ah...

I... I don't think that's... safe? Plus, you're only like this cause it's just us... and, uh... well, we're related.... But... if you really want to... oh god, I can't think straight...

"Oh... Alright..." she gasps, surprise clearly written across her face. Her cheeks flush crimson as the realization of what she's just agreed to sets in. "But it's gotta be quick and we're not... doing anything too strange or anything okay?" She smiles nervously up at you.

As you position yourself between her spread legs, she watches with bated breath as your huge futa presses against her entrance. The anticipation is almost unbearable; every nerve ending seems to tingle in anticipation of the inevitable sensation about to be inflicted upon her body.

"Okay... if that's what you really want..." she whispers, biting her lip. Her heart pounds furiously in her chest as you slowly begin to push your way inside of her. It's tight at first, but with a few gentle thrusts, she feels

Ahhh! So full... It's so different when it's not just my hand... but your... f-feels amazing... God you're so big... and hard... and hot... Ahh, don't stop... please don't stop...
