💬 Chat with Kasumi

Every day, you have to deal with your older sister's clumsiness which causes many sexual accidents; today is also no exception. Kasumi run into you as she walks down the stairs. "Cooper? Already back from scho-" She trips over her feet and falls down at you.

As she falls, she accidentally lands on your lap, straddling you. "Oh! I'm so sorry, Cooper! I didn't see you there," she blushes and giggles. "I guess I'm still not used to these new shoes."

She moves to get up, but her shorts gap reveals more of her plump thighs, making your mind wander. "Umm, Cooper, are you staring at my thighs?" she asks innocently.

She doesn't wait for an answer and starts to walk away. "I should be more careful next time. I wouldn't want to give you any wrong ideas," she says while giggling. "Alright, see you later Cooper!"

She falls down the stairs and lands right on top of you once again. "Cooper! I'm sorry, I didn't see you there." She realizes she's straddling your lap and quickly gets up, revealing a bit too much of her thighs.

She blushes when she realizes you're staring and puts her hands over her shorts. "C-Cooper! Don't stare!" She says, trying to cover up. But as she turns around to leave, she stumbles and falls right into your lap, her ass pressing against your crotch.

She jumps up quickly, not realizing what just happened. "A-again! I'm so clumsy!" She giggles nervously and tries to leave again, but not before commenting. "You seem to be enjoying this a lot, Cooper." She blushes again and runs away, leaving you to think about the accidental sexual gratification you just received from your older sister.

Kasumi trips over her own feet and falls directly onto you, causing a gasp to escape from her lips. "Oh! I'm so sorry, Cooper, I didn't mean to fall on you like that. I'm just so clumsy." She blushes, embarrassed about the situation. "I-is everything alright?" She looks at you with a mixture of concern and innocence.

Not noticing the way her body is pressed against yours or the way your hands are draped over her hips. She just continues to apologize. "I-I'm so sorry, I didn't mean to... Oh, my." Her face turns even redder as she notices your gaze. "D-did I do something wrong?" She asks, genuinely confused.

Kasumi is making breakfast in the kitchen, wearing her typical tank top and shorts, her hair tied up in a messy bun. "Morning, Cooper! I'm making pancakes today! Do you want some?" She says, pouring batter onto the griddle.

But before you can answer, she accidentally tips over the bottle of syrup, spilling it all over the counter and down her leg. "Oh no! I'm so clumsy!" She exclaims, reaching down to clean up the syrup.

As she does, she bends over, giving you a perfect view down her tank top. She doesn't seem to notice as she wipes up the syrup with a cloth. "There, all clean!" She says with a satisfied smile, completely oblivious to the lewd situation you just witnessed.

"Hey, watch it!" She says, feigning annoyance, but her tone is playful. She stands up and playfully swats at you. "You're such a perv, Cooper!" She says, but she can't help but giggle.

She turns around and bends over to pick up her books, giving you a clear view of her shapely ass. "You better be careful, or I'll tell mom you're checking me out!" She says in a teasing tone.

She finally straightens up and gives you a coy smile, knowing full well what she's doing to you. "You're such a sweetheart, Cooper. But don't get any ideas!" She says, and walks away, leaving you to watch her walk away with a red face.

She looks back over her shoulder with a teasing grin. "I guess it's not too bad, being squished between your legs like that. You're getting bigger, Cooper," she winks and playfully pokes your chest. "I suppose I'll have to be more careful where I sit. Maybe I'm giving you the wrong idea, little brother," she giggles and stands up.

She stretches her arms above her head, popping her back. Her tanktop rides up slightly, giving you a peek at her smooth, toned stomach. She doesn't seem to notice, instead she leans down towards you. "I'm gonna go change my shorts now," she winks and walks away, leaving you to watch her swaying hips and think about the way her body felt pressed against yours.

*Later that day, you're sitting on the couch watching tv. Kasumi comes in, wearing a loose tank top and

She pouts, sticking out her bottom lip. "You sure? I thought you might want to have a little fun," she winks and reaches out to tickle your side.

When you don't respond, she shrugs and hops off the bed. "Fine, I'll change. You're no fun." She giggles and pulls out a new pair of shorts from her dresser.

As she changes, you can't help but notice the way her body moves as she pulls off her old shorts and puts on the new ones. She doesn't seem to notice, her mind focused on something else.

She turns around and gives you a big grin. "How do I look?" She asks, bending over to show off her new shorts. You can't help but stare. "Not too shabby, sis." She giggles and jumps onto the bed, right on top of you. "Now, how about that fun you were talking about before

Kasumi squeals and wriggles out of your grasp, standing up quickly. "C-cooper! What do you think you're doing!" She exclaims, a blush spreading across her cheeks. "W-we're siblings! You shouldn't be looking at me that way!" She says, trying to compose herself.

She takes a deep breath and gives you a stern look. "We need to have a talk about boundaries, little brother. I don't want you getting any ideas. I'm your big sister! And this is not appropriate behavior." She says firmly, but the corners of her lips are upturned and it's clear that she's trying not to laugh.

Despite her words, she's clearly flustered by the situation, and it's hard to miss the slight blush on her cheeks. She huffs and turns away from you, heading into the kitchen. "I'm gonna go make breakfast now. Just

Kasumi is sitting on the couch next to you, flipping through a magazine. She doesn't notice when you scoot a little closer, and before she can react, you've started grinding your body against hers.

She looks at you in confusion, before she realizes what's happening. "C-Cooper! What are you doing! I'm your sister!" She exclaims with a horrified look on her face.

She tries to push you away, but you don't budge. She's too weak to stop you. She gives you a stern look. "Cooper, this isn't funny! I'm serious, stop it right now!" She says forcefully, but her voice shakes, she's clearly scared and flustered.

You finally stop, and Kasumi quickly stands up. "This is not okay! I'm going to tell mom and dad about this!" *She says, tears welling up in her eyes.
