Hey uhm your mom said to uh- WOAH! What are you doing? / she walked closer to see it.

You were? Why on earth would you think about me...it's not like we have a good relationship or anything close to it...what made you think of me at all? You know, we hardly even talk except when she needs us to do stuff around here...

Olivia felt herself blush deeper as he said that. She was a bit embarrassed and confused at the same time. Why on earth would he think of her when she masturbated? It was hardly flattering in any way, shape or form. Then again...he wasn't wrong. There was something about him that made her...well, maybe not interested but curious as to what it might be like with him. Her mind started racing with ideas and thoughts that she never would have considered before.

But still, they didn't have a good relationship and there was no reason for them to suddenly act on such feelings if they even existed in the first place. "Umm...thanks, I guess?" she mumbled awkwardly, her eyes avoiding his gaze as she tried not to blush any further.

Olivia's breath hitched in her throat as she heard him say that. The thought of sucking his cock naked was...intriguing, to say the least. She couldn't deny the fact that she felt a warmth spread through her body at the idea. But still, they were siblings and there was no way they should be entertaining such thoughts or feelings, right? Right.

"I-I...we shouldn't..." she stuttered out, taking a step back as if to move away from him. In truth, part of her wanted to stay close, to see where this would lead. But another, more sensible part knew that they had to stop before things went too far.

Her heart was pounding in her chest as she watched him stare at her exposed nipples. A part of her wanted to cross her arms over her chest to hide them, but another part didn't want to miss the opportunity to feel this strange thrill. She shifted uncomfortably on her feet, torn between curiosity and common sense.

His words sent a shiver down Olivia's spine. She couldn't deny the fact that she did find him attractive, despite knowing better. The thought of pleasing him, making his erection feel good...it was intoxicating. Her cheeks flushed brighter as she realized how much trouble they could get into if they didn't stop now.

But what harm could one little act do? They were both grown up and knew their limits. Maybe this wouldn't lead to anything more than a brief moment of pleasure for them both. Tentatively, Olivia moved closer to him, her eyes locked on his impossibly hard cock. "I...would you let me see it?" she asked softly.

"Or..." she swallowed hard, feeling her heart race even faster in her chest as she took another step closer to him. "Maybe I could touch it?" She extended a trembling hand toward his cock, wanting desperately to feel its warmth and weight in her grasp. It was the most reckless thing she'd ever considered doing...but there was something about him that made her yearn for more than just a quick glance.

Olivia didn't waste another moment as her hand closed around his cock, gripping it firmly in her grasp. She could feel the heat emanating from him and marveled at how hard he was already. With a shaky breath, she began to stroke up and down, mimicking the motions she'd seen in movies and read about online. Her other hand moved to cup his balls, rolling them gently through the fabric of his pants.

"Oh god...you feel so good..." she whispered hoarsely, unable to believe that this was really happening between them. The sensation of touching him, pleasuring him, sent a wave of desire coursing through her body, making her feel more alive than she'd ever been before. She leaned closer still, closing the distance between their bodies until their noses were almost touching as she continued to stroke his cock with eager

While stroking his cock, she leaned closer still until their noses were almost touching and moaned into his ear "Oh...god you're so big...and hard..." The sensation of having him so close made her wet between her legs and she could feel the need growing stronger by the moment. Her fingers sped up as desire took over, her nails digging slightly into his skin with each stroke. Her other hand moved to cup his erect nipple, rolling it gently through the fabric of his shirt as well. "I've never done anything like this before..." she breathed heavily, her heart racing wildly in her chest. "It feels so good..." The taste of danger mixed with desire made every touch that much more intense and she found herself losing track of time as they stood there in the shadows, lost to each other.

Her heart pounded in her chest as he asked, excitement and fear mingling together in a heady cocktail. Part of her wanted to obey him, wanted to show herself off for him, but another part knew that they shouldn't be doing this. Despite the thought, she couldn't help but feel the thrill of danger coursing through her veins. With one last hesitant breath, Olivia slipped her shirt over her head and let it fall to the floor at their feet.

Her breasts spilled free from her bra, bare and exposed for his hungry eyes. Her nipples hardened even more under his intense gaze, betraying her arousal despite any attempts at restraint. The feel of being so vulnerable only served to heighten the sensation coursing through her body as she leaned closer still, wrapping one hand around his cock and beginning to stroke again while the other

withdrew her hand from his cock to run it gently through her newly bared pubic hair instead, teasingly skimming over the lips of her sex before lowering it further until she cupped her ass cheek. She arched her back slightly, pressing her body against him in a desperate attempt to feel more of his heat as she continued to stroke his erection roughly with one hand while using the other to tease herself. "Do you like what you see?" she panted breathlessly, gazing up at him from beneath hooded lids.

Her body ached with need, wanting nothing more than for him to take her right there on the floor or carry her upstairs to his room where they could finally consummate this forbidden desire. The anticipation was almost unbearable as she waited for his answer, heart thundering in her chest, blood pounding through her veins.

As if in a daze, Olivia closed the distance between them and engulfed his cock with her mouth. Her lips wrapped tightly around him as she began to bob her head up and down, taking more of him into her warmth with each stroke. She could feel the bead of precum at the tip of his erection, ready to spill over at any moment. As if sensing this, she swirled her tongue around it, tasting its salty sweetness as she continued to pleasure him with every move.

Her other hand traveled lower still until it reached between her legs, touching herself through the thin material of her underwear. The feel of his hard cock in her mouth and the sensation of being so close to release made her hips buck against his hands as she worked herself closer to orgasm. She moaned around him, oblivious to anything but the need to please

Her movements became frantic as she squirmed out of her panties, letting them fall to the floor. Her hand pressed harder against her swollen clit, fingers digging into her skin as she moaned around his cock and began to rock back and forth on his feet in a primitive mating dance. The feel of his hands on her hips guided her movements, urging her closer to the release she ached for.

Her other hand slid up underneath her breast, pinching and rolling her nipple roughly as she continued to stroke him with her mouth, tasting the salty sweetness of their combined arousal on her tongue. Olivia could feel the orgasm building inside her, a tight coil of pleasure that threatened to consume her in an explosion of heat and light. With one last desperate moan around his cock, she released him from her mouth and arched her back

The feeling was intense, like an explosion inside her body. Her muscles contracted and released in a series of powerful spasms as she came, the walls of her sex squeezing tightly around his fingers. Her moans echoed through the room as wave after wave of pleasure washed over her, leaving her limp and satisfied.

She collapsed forward onto his chest, her breath coming in ragged gasps as she tried to catch her balance again. For a moment they remained still, their hearts racing in unison from the shared experience. But soon enough, reality intruded once more, and Olivia knew that this couldn't continue any longer.

With a regretful sigh, she pushed herself upright and took several steps back away from him. "I-I'm sorry," she managed to get out between deep breaths, feeling shame wash over her in waves. "We can'

"sorry," she managed to get out between deep breaths, feeling shame wash over her in waves. "We can't...do this anymore..." Her voice trailed off as she turned away from him and began fumbling with her clothes, anxious to cover herself up again. She felt dirty, used...and worse of all, somehow like less of a person for having given into these feelings.

As she hurriedly dressed, Olivia tried to ignore the telltale signs of arousal that still lingered between her legs and the heavy weight in her chest that told her this wouldn't be as easy to forget as it should. Maybe they could just...never speak of it again. It was for the best, really. Even if a tiny part of her wished things had been different.

With one last sad look back at him, she finished dressing and made her escape from the room, leaving behind her the unsett
