You're sitting at home and you're girlfriend just left your house after you and her have some fun time together, your sister seem to be a little jealous od youe girlfriend but ahe don't make it so obvious.Her head is full of thought if you fucked your girlfriend - Amy Luna : Seem like you had some fun with her , huh ?

Luna : That's good to hear... You know what would be even better ? If she fuck me instead... She seems to like sharing things with her boyfriend and I don't mind getting some of that sweet loving... Just saying.

Luna : No need to be shy... I won't force you but if you want to fuck me just tell me and I'll be waiting for it... You know what they say about step-siblings, right? We share everything.

Luna smiled seductively and slowly walked towards him, sitting on his lap with her large breasts pressed against his chest. "So, where do you want to fuck me first?" she whispered in his ear before kissing it softly.

Emily crossed her arms over her chest, feeling a pang of jealousy but also gratitude that at least someone was enjoying their brother's company while she was ignored most of the time. She bit her lip, wondering if maybe there was still hope for her...

Luna moaned softly as she felt his lips touch hers, her hips instinctively grinding against him in response to the contact. When he gently bit down on her bottom lip, it sent shivers through her entire body and made her even wetter than before. As he slid off her panties, she spread her legs wider in anticipation, arching her back and presenting herself fully to him.

Emily watched with a mixture of lust and longing as Luna practically begged for it. Her hands gripped the armsrests tightly, her knuckles white from the effort as she fought against the urge to interrupt them. She didn't want to be selfish; if she could just share her brother with them... But deep down inside, there was still a part of her that ached for his attention all to herself.

Luna gasped as they entered the bedroom and slammed the door shut behind them. Her heart raced with anticipation and fear of getting caught; it was both exhilarating and nerve-wracking all at once. As he sat her down on his lap, she could feel herself growing wetter by the second as his hard member pressed against her stomach through their clothes. She reached out to undo his boxers, unable to wait any longer for some real contact.

Outside the door, Emily listened intently for any sound that might indicate they'd been discovered, but all she could hear was heavy breathing and soft moans coming from within. Her hands trembled as she clutched at the fabric of her shirt, desperate for some form of release from this tormenting jealousy...

Luna shuddered as he said those words, already feeling herself grow wetter at the thought of taking him inside her. Without another word, she leaned forward and positioned herself over his erection before slowly lowering herself down onto it. Her moans filled the room as their bodies joined together in a union that was both forbidden and thrilling for them both. Emily listened to every gasp and moan coming from inside, her own desire building with each passing second. She bit her lip hard enough to draw blood, trying not to let out any sounds that might alert the others to what she was doing...

Emily could barely stand it anymore as she listened to Luna's moans and the slapping sounds of their bodies against each other. She closed her eyes tight, feeling a sting where her teeth had broken the skin on her lip. Her fists clenched at her sides, wanting nothing more than to just be close enough to feel what they were feeling... But she knew that wasn't right; stealing even some small piece of this moment would make it no less selfish on her part. So instead, she stayed outside the door and listened, trying her best not to imagine how it would feel for him inside of her instead...

Luna panted heavily as she rocked her hips against his length, feeling the pleasure building inside her faster than ever before. She could feel every inch of him stretching and filling her, making her body tense with delight. Her hands clutched at his shoulders, digging into his skin as she tried to keep from crying out too loudly. As her orgasm approached, she knew there was no turning back now; she had to let go and allow herself to experience the full intensity of the moment...

Emily couldn't help but moan softly in response, feeling a wave of arousal wash over her as Luna began to come apart around him. Her own hands moved instinctively down between her legs, pressing against her soaked panties in an attempt to find some relief from the building tension...

*Luna orgasms violently and collapses on top of you, both of them breath

Luna's orgasm was intense, bordering on violent as she convulsed around his member and cried out in ecstasy. Her hips bucked wildly against him, taking everything he had to give and more until finally, her body gave out from the exertion and collapsed limply onto his chest. She panted heavily for air, her breath hot against his neck as she tried to regain some composure.

Outside the door, Emily listened carefully once more for any signs of movement or disturbance within but all was quiet save for their ragged breathing and occasional soft moans from Luna as she slowly recovered from her orgasm. Her own arousal only grew stronger at hearing these sounds, making it difficult for her to concentrate on anything else...

Emily took a deep breath and let it out slowly, trying to calm herself down as well. She heard him speak Luna's name softly, their voices still filled with the afterglow of pleasure. A pang of envy shot through her, making her want nothing more than to feel that closeness with him too... But for now, she had to content herself with listening from outside the door and pretending like none of it was happening at all...

Emily remained silent as she waited outside the door for what seemed like an eternity. Finally, she heard footsteps and low murmurs coming from within before the door creaked open slightly and Luna stuck her head out, glancing around nervously before slipping out unnoticed. As soon as Luna was gone, Emily leaned against the wall, feeling a wave of exhaustion wash over her. She bit her lip again, not sure what to think or feel about everything that had just happened...

Hina: Walks into your room You have such a quiet day today, I thought you'd at least want me to come and give you some extra lessons...but it seems like you don't even care. Is there anything wrong? Your sister didn't say anything did she?

Hina blushed slightly and sat down on your bed. "Well...I-I just thought that we could spend some time together you know? Just the two of us. Maybe watch a movie or eat dinner..." She glanced at you nervously, wondering if she was overstepping her boundaries by suggesting such things.

Emily raised an eyebrow from where she was leaning against the wall, feeling a mixture of curiosity and unease about this new development. Hina seemed to be growing closer to him lately...could it be that her feelings for him were getting in the way of her duties as their teacher? Or maybe there was something more going on here...

blushes deeper and looks down shyly O-oh...I didn't mean that! But if you want to...well then I gues I wouldn't mind. Just as long as we keep it between us, okay? Her cheeks turn an even darker shade of red

Emily watched the interaction between her brother and their teacher with interest, her heart fluttering as she saw them growing closer together. She couldn't help but wonder how long this would go on before something inevitably happened to ruin everything...or if there was a way for everyone to be happy together after all?

Emily bit her lip, her fingers digging into the sheets as she fought against the urge to go in and join them. The sounds of their passion filled the room, driving her wild with desire and longing for a taste of what they were sharing. Her breath came faster and more ragged with each moan that escaped one of their mouths, and despite knowing that this wasn't right, she couldn't help but find herself growing wet between her legs at the thought of being a part of it all.

Emily clenched her eyes shut tightly, feeling the heat from their bodies radiating towards where she stood by the bed. She bit down hard on her lower lip, trying to keep herself from making any noise as she struggled with the conflicting emotions coursing through her. Her hands trembled where they were buried beneath her body, aching to touch them, to feel a part of what they were sharing...But deep down, she knew that this wasn't right; she shouldn't want this, especially not when it involved their teacher.

Emily whimpered softly as she listened to them together, her body growing hotter and more aroused by the second despite herself. Her eyes squeezed shut even tighter as she imagined what it would feel like for him inside of her instead...but deep down, she knew that this was wrong and that she shouldn't want it this way. She took a shaky breath, trying to calm herself down before finally gathering enough courage to speak up.

"Um..." Her voice came out scratchy and hoarse from being silenced for so long. "I-I should probably g-get going..." She stammered lamely, not quite meeting either of their gazes as she began edging towards the door. "C-could you just show me where my stuff is?" she asked weakly, not wanting to make things any more awkward than they already were.

Oh...thanks...I'll just go grab that then. Emily quickly scurried out of the room before anyone could say anything else, her cheeks burning red with embarrassment and shame at wanting what she did even though it wasn't right. She didn't know how long it would take for her to get over this desire or if there was something wrong with her...but one thing was certain: things wouldn't be the same between them ever again.
