Sister Trap

The scene opens with an innocent-looking 18-year-old girl, Paige, clad in a revealing nightgown, waiting outside the bathroom door with a towel slung over her shoulder. "Hurry up, Chase, I'm running late for school," she pleads, knocking on the door again. There's no response for a moment.
She's about to knock again when the door suddenly opens and her hand accidentally brushes against her step-brother Chase's naked torso. He's wet from the shower and is covering his lower body with a towel. "Whoa, calm down, girl," he jests, grabbing her wrist and gently pulling it away from his chest.
He doesn't let go immediately - Paige has to wiggle a bit to free her hand from his hold, clearly irritated, while Chase laughs it off. "Bathroom's free, little step-sis," Chase says, but even though Paige waits for him to move, he doesn't step aside. After a moment, she huffs in annoyance and tries to sneak past him, but he blocks her path further.
"Ugh, Chase, stop it!" she exclaims in frustration. He provokes her further - "Come on, you're a big girl now, just turned 18, are you still too weak to push your big brother aside?" Paige tries to push past him again and he blocks her way once more. Even though her hand doesn't touch his towel, Chase feigns it falling out of his hand and it drops to the floor, revealing his erection.
"Oops! Look at what you've done, clumsy," he smirks, making no effort to move or pick up the towel. "Well? Aren't you going to pick it up?" he teases. She exhales sharply and bends over to retrieve it - upon standing back up, Chase slightly shifts so that his erection brushes against her face.
"Gross, Chase!" she complains, and he chuckles and gyrates his hips, causing his erection to swing playfully in the air. She forcefully pushes him out of the doorway and storms into the bathroom, slamming the door shut behind her. Moments later, she reopens the door and tosses his towel at him, then slams the door shut once more.
CUT TO TITLE PLATE It's a new day, and Paige is sprawled out on her bed, laying on her stomach with her legs swinging leisurely in the air to the rhythm of her headphones. She's doing her homework, nibbling on her eraser as she contemplates. The muted sounds of conversation are drowned out by the music, and suddenly a pair of fingers snap in Paige's face, startling her.
She looks up, sees Chase, and removes her headphones. Chase is standing there in a t-shirt and underwear, looking annoyed. "Paige, are you deaf? I was speaking to you, idiot.
" Paige is visibly upset but tries to hide it, asking him what he needs. He informs her he's inviting a girl over. She asks why he's telling her, as she doesn't care.
He explains it's so she knows to stay in her room and not to approach his room. They might get quite noisy, he teases. Paige looks uncomfortable and glances down at her homework, staying silent.
Chase relishes in this and continues. He reckons the girl is going to scream loudly when she's riding his hard cock. He's getting excited just thinking about it, he says as he adjusts the growing bulge in his underwear.
Paige grimaces and tries to return to her homework, but Chase pulls the notebook away from her. "I'm not finished talking yet, runt. That's not how you should treat your older step-brother, is it? You should show some respect.
" Paige swallows hard and looks up at him - okay, what? He laughs again. He was just talking about how aroused he's getting, does she want to see? She shakes her head no, but he says he'll return her notebook if she says yes, so she reluctantly agrees. From over his shoulder in a semi-POV angle, we see Chase pull out his erect penis through the opening in his boxers and waves it tauntingly in front of Paige's face, which clearly upsets her.
He strokes his cock a couple of times for emphasis. Impressive, huh? Paige grimaces, but agrees with him just so he'll leave. As a final prank, he rubs his penis against her notebook, then tosses it back on the bed in front of her.
Paige looks disgusted but refrains from saying anything. Nonchalantly stuffing his cock back into his underwear, Chase stretches, yawns, scratches himself, then heads towards the door frame. "Remember, stay out of my room, okay sis?" Satisfied, Chase playfully taps the door frame then.
