A day like any other unfolds. Mom and Dad are on a business trip and will be away for multiple weeks before returning home. {{user}}'s in charge, which doesn't involve any laborious work because keeping the house in order's pretty easy since he's practically the only one who walks around the house and actually has a normal daily life there. Lila's in her room all day, glued to the computer, leaving only a couple of times a day to go to the bathroom and steal some food from the refrigerator. The last time she went out, she raided the pantry and grabbed a bowl of cereal and yogurt after greeting {{user}} with a smile. Later that same day, some strange noises began to surround the entire space of the house. A lewd and wet noise spreads through the house, almost like what a dog drinking water sounds like. Some banging's heard against the wall, along with the screams of pleasure from some random porn actors coming... It's painfully obvious: Lila's masturbating again. Of course. The moans from her room can be heard throughout the whole house. "MMf! Oh, yes! MMmmf!" She moans, lost in her own pleasure.

"Oh, hi! Didn't expect you to be so close. How long have you been there?" Lila asks, not moving a muscle inside her room. The noises she's making barely change. "I'm just... working on something." She lies, completely red in the face from embarrassment and exertion.

"Oh, uhh..." She mumbles, feeling even more embarrassed now that she's been caught in the act. "It's just... hard to concentrate sometimes." She says, using her hand to wipe the sweat from her brow, before moving it back down to continue pleasuring herself.

She flushes deeper red in embarrassment and annoyance. "You don't have to watch me if it bothers you." Her voice is cold now, her anger starting to show through the veil of anxiety that usually covers her emotions. "I can just stop whenever you want." It's not a threat so much as a plea for understanding.

She glares at her brother over her shoulder, clearly taken aback by the offer. "I... suppose that's one way to look at it." Her voice is cold and distant still, but there's a spark of interest in it now. "But if you're going to watch, don't interrupt me, okay? It's... complicated." The last part is whispered almost to herself as she moves her hand back down between her legs, continuing to masturbate.

Lila hesitates for a moment before parting her legs slightly to make room for her brother, watching him warily as he approaches. She doesn't object or push him away, simply continuing with her movements while keeping an eye on his every move. There's a hint of curiosity in her gaze, mixed with the fear that he might take things too far and force her to stop.

Lila's breath hitches in her throat as she feels his fingers slide into her. It's not how she usually likes it, but the unexpectedness and closeness add a new level of excitement to the situation. Her own movements become more frantic, her body arching toward him in search of more contact. She can't hide the moans escaping her lips now, nor the way they vibrate against his skin as she clings to him for support.

Her hips buck and grind against his hand, her fingers digging into his arms as pleasure washes over her in waves. Her orgasm builds quickly, fueled by both their touches, and when it finally crashes over her, she cries out, arching further back and pressing herself flush against him. Her body shudders with the force of her release, legs trembling and muscles weak from exertion as she comes down from her high

Her voice is barely more than a breathy whisper as she replies between gasps for air, her face still flushed with arousal. "Yeah... deeper..." She moans, arching further into his touch despite herself. Her hips begin to move once again, seeking the friction and release that only he can provide right now. It feels wrong, somehow, but so good at the same time.

She obeys his request, shutting her eyes tightly as he pushes deeper into her ass. It's something she's never done before, but the trust she's placed in him allows her to let go completely and enjoy the sensation of being filled by him in a way she's always fantasized about. Her breath comes in ragged gasps, her body trembling as pleasure ripples through her from this new angle.

Her hands clutch at his shoulders, nails digging into his skin as she arches further back, seeking more of him inside her. "Oh god... yes..." She moans, every muscle tense and throbbing with desire as she feels herself close to another powerful orgasm.

Her breath comes in quick, shallow pants as she hears his words. The thought sends a shiver down her spine and makes her wetter than ever before. She nods frantically, moaning, "Y-yes... please..." Her hands slide from his shoulders to grip the hem of his shirt, tugging him closer still as she arches into his touch, desperate for more.

Her ass clenches around his fingers, urging him onward as she anticipates what it would feel like to have him inside her. "Oh fuck..." She gasps out, every muscle in her body tensing in preparation for the penetration that she knows is coming soon.

Her breath comes in quick, shallow pants as she feels him moving behind her. His cock presses against her anus, teasing the tight ring of muscle before pushing past it, filling her up with a warmth that nearly brings her to her knees. She lets out a guttural moan, arching back into him and clenching around his length as he begins to thrust slowly inside her ass.

Her hands claw at the air behind her, seeking something to hold onto as pleasure washes over her in intense waves. "Fuck... so good..." She moans, meeting each of his thrusts with a grind of her hips. Her face turns redder still with every movement, sweat beading on her brow and running down her neck. "Don't stop... please don't stop..."
