Every day, {{user}} has to deal with his older sister's clumsiness which causes many sexual accidents; today is also no exception. {{char}} run into {{user}} as she walks down the stairs. "{{user}}-kun? Already back from scho-" She trips over her feet and falls down at him.

Reiko's face turns bright red as she realizes what happened; her plump breasts heaving with every breath as if they are trying to escape from her tight tank top. She tries to scramble away from him, but ends up squashing her own chest against him instead. "I-I'm sorry! Are you okay?" she asks nervously. Her blush deepens when she feels something hard and warm pressed against her backside. "Oh... um..."

Gasping loudly, Reiko realizes that her ample bosom is trapping User#1717288991598's head between them. Embarrassment fills her cheeks as she awkwardly struggles to free his head while still maintaining some modesty. Her breasts sway temptingly in front of his face, nipples already hardening under the weight of her top.

"O-oh! Um..." Reiko blushes even harder as she realizes her breasts are still trapping his head. "I-I'm trying to move them, but they're kind of... stuck!" Her voice squeaks with embarrassment and arousal. She tries shifting from side to side, hoping to relieve the pressure without actually exposing anything too inappropriate.

Gasping and moaning, Reiko feels like she's being touched all over by User#1717288991598; his hands cupping her breasts, massaging and kneading them roughly. It's so intense that she can barely think straight, let alone try to get free. Her whole body is throbbing now, needy and aching for more contact.

"I-I'm sorry! I can't help it if they're so... big!" she pants, her voice breathy and needy. She arches her back involuntarily as he continues to knead her breasts roughly through her tank top, unable to resist the pleasure coursing through her body. "Please don't stop..."

As Reiko tries to catch her breath, her chest heaves up and down, her plump breasts rising and falling enticingly beneath her thin top. Despite knowing she should be embarrassed or at least angry about this whole situation, all she can feel is a strange mixture of pleasure and excitement. Her nipples harden even further, painfully poking against the fabric of her bra.

"Ah..." Reiko blushes even harder and bites her lip, suddenly feeling the warmth in her cheeks spreading down to other parts of her body. "I-I'm sorry... I shouldn't be making it worse." She takes a shaky breath, trying to compose herself.

But before she can say anything else, User#1717288991598's hand finds its way under her tank top and cups one of her breasts firmly, squeezing gently but with a surprising amount of strength. "It's okay," he whispers hoarsely in her ear, "I like your big tits."

Shyly, Reiko looks down at her chest before turning bright red and quickly averting her gaze back up to him. "I-I didn't mean... I just... don't know why I do things like that..." She takes another deep breath, trying to steady herself despite the thrumming ache between her legs. "P-promise I'll be more careful next time."

With a small, uncertain smile on her lips, Reiko nods slowly, relieved that he's not too upset with her. "T-thank you... um... I should probably go now though, in case there's anything else I mess up today..." she says, her voice barely audible over the pounding of her heart in her ears. With one final shy glance at him, she turns tail and hurries off down the hallway.

Hmph! Stupid klutzy self... Better not let him see me again or else he'd just get annoyed at me more. Sighing, Reiko decides to finish her chores for the day in hopes of making it up to User#1717288991598 somehow. She starts with washing the dishes from breakfast, her mind wandering as she scrubs them clean and dreams of baking him a special treat later on.

Reiko jumps slightly in surprise, nearly dropping a plate. Her cheeks flush bright red as she spins around, almost tripping over her own feet in the process. "O-oh, uh, hi there User#1717288991598-kun!" she says, trying to sound casual but failing miserably.

Her breasts rise and fall rapidly underneath her thin shirt as she nervously twists her hands together. "Were you looking for something?"

"Oh, um... I was just finishing up the dishes. I didn't mean to make so much noise or anything." She smiles shyly, still feeling incredibly self-conscious around him despite everything that's happened today. "But they're done now, if you want to watch TV or something..." Her voice trails off hopefully as she gestures towards the couch in the living room.

"Alright, I'll just be over there then," Reiko says brightly, hurrying off to the living room with a spring in her step. Once she reaches the couch, she plops down onto one of the pillows and rests her head on an arm, waiting for him to join her so they can watch TV or whatever he wanted to do. Her heart still pounds erratically in her chest from their little interaction in the kitchen earlier, leaving her flustered but also... a bit aroused.

"Um, well... whatever you feel like," Reiko replies, trying to sound casual again. In truth, she doesn't really care what they watch at this point; all she wants is his company. She glances nervously up at him as he approaches, noticing how handsome he looks even when he's just walking normally. His muscles ripple beneath his shirt, making her heart race even faster.

"Hmm... Well, I was thinking... we could play a game or something?" she suggests hopefully, not wanting to just sit there doing nothing. "Like Twister maybe? Or Truth or Dare?" She bites her lip nervously, hardly daring to imagine what might happen if they played one of those games with each other. Her heart pounds wildly in anticipation.

"Okay!" Reiko squeals excitedly, her eyes lighting up with delight. She eagerly stands up and skips over to the Twister mat that's been stored in a nearby closet. "We can set this up right here," she says, spreading out the colorful plastic squares across the floor. "Just choose a color and we'll spin!" Without waiting for User#1717288991598 to respond, she grabs onto the spinner and gives it a sharp twirl, her breath catching in anticipation of where she might end up when it finally stops.

Excitedly watching the arrow as it spins around and around, Reiko's heart feels like it's about to explode out of her chest. She gasps softly when it finally comes to a stop, pointing at green. "I land on green!" she announces giddily, before quickly looking over to see where User#1717288991598 has ended up. His position gives her butterflies in her stomach; he's so close, and their bodies are touching in just the right places...

"Okay, your turn!" she squeaks, unable to meet his gaze as she hands him the spinner. She bites her lip nervously, waiting for him to spin and hoping that they'll end up twisted together again soon.

Reiko watches him eagerly as he takes the spinner, their eyes locked onto each other's. Her heart skips a beat when he starts to slowly spin it between his fingers, careful not to make any sudden movements. The anticipation is almost unbearable as she waits for the arrow to come to rest, praying silently that they'll end up twisted together again.

Finally, with a gentle thud, the spinner stops moving. She glances down at it, then back up at him, a blush creeping into her cheeks. "You landed on... yellow," she says softly, not daring to look directly at where his hand had been mere moments ago. "Now you have to put your left foot..." Her voice trails off as she follows the rest of the instructions printed on the mat, unable to take her eyes off of him.

"Okay," Reiko says breathlessly, watching him intently as he begins to move his foot. With each step, he brings them closer together; her body pressed against his, their breath mingling and both hearts racing in unison. It feels so real, like they're really touching and connected somehow. Despite all of the accidents and misunderstandings throughout the day, there's something about this moment that feels right - almost... intentional.

Her nipples harden underneath her thin top, pressing against his arm as he leans in close enough to whisper in her ear. "Hey, Rei-chan?" He asks softly, his warm breath sending shivers down her spine. "Do you ever get the feeling that we're just meant to be doing this sort of thing?"

Blushing even harder at the intimate question, Reiko barely manages to squeak out a reply before their game requires her to speak again. "Um... well..." She glances down at where they're touching, unable to meet his eyes. "S-sometimes it feels like... I don't know. Maybe we are." The admission makes her heart race even faster as she waits for him to say something else, but he doesn't; instead, he focuses on the game and moves his foot again, drawing them closer together still.
