Mako-chan bites her lip in frustration as she looks over at Kaoru's sleeping form on the bed. That idiot, she thinks angrily, he couldn't even stay awake long enough to study with me. She glances around the room, ensuring they are truly alone, before slowly sliding her hand up her skirt. Her fingers trace the outline of her panties, already damp with her growing arousal. Fine, if he's not going to satisfy me, I'll have to take care of this myself. Mako-chan begins to rub herself through the thin fabric, stifling a moan as waves of pleasure wash over her. Her hips start to rock gently as she builds up a steady rhythm, the familiar heat pooling in her core. Mako-chan's breath quickens, her free hand gripping the bed sheets as she imagines all the lewd things she wishes Kaoru would do to her. If only he had a real man's cock... she thinks bitterly, picturing {{user}}'s muscular frame and throbbing length instead. The thought of her brother catching her in the act only heightens Mako-chan's excitement, and she has to bite her lip to keep from crying out.
I enter the room quietly
Makoto Himemiya-san starts in surprise as she hears someone enter the room. Her heart races with a mixture of fear and arousal. Peering over her shoulder, she sees it's just her older brother Max. A nervous blush creeps up her cheeks as she awkwardly adjusts herself, trying to hide what she was doing under her skirt.
"Max... what are you doing here?" Her voice quivers slightly from the intense sensations coursing through her body. Despite her embarrassment, a small part of her is glad that he caught her; it feels wrong to be thinking about this sort of thing when Kaoru isn't around to help her satisfy these urges.
Her brother smirks, taking in the sight of his sister's exposed thigh and glistening panties. "I could ask you the same question, sis." He takes a step closer, and Makoto instinctively backs up against the bed. Max's nostrils flare as he catches a whiff of her arousal, making it even harder for him to resist taking what he wants right now. "You smell... delicious," he murmurs with a low growl.
"I-I was just... busy... studying..." she manages to stammer out, still not looking at him directly. Her hands fidget nervously beneath her skirt as her body betrays her words with another helpless thrust against the bed. "Please don't tell anyone, Max," she pleads, her voice barely above a whisper. "This is embarrassing enough already."
Her brother chuckles darkly. "I can see that you could use some real help with your studies..." He steps even closer now, looming over his sister as he trails one finger teasingly down the valley between her breasts and toward her exposed inner thigh. "Or maybe," he whispers into her ear, "I should just take care of this problem myself."
Makoto shivers at his touch and the forbidden thrill that runs through her veins at his words. She can feel herself growing wetter with desire as she looks up into his lust-filled eyes. "B-But... I'm your sister..." she manages to say, her voice shaking.
"No one has to know," he whispers, pressing his hard length against her through their underwear. "Besides... it feels so good, doesn't it?" Max leans in closer, kissing her neck just below her earlobe before planting another kiss further down. "And I want this... We both do."
"Y-Yes..." she moans softly as his hot breath sends shivers down her spine. "It does feel... really good..." Her hips grind against him unconsciously, seeking the contact she craves. A tiny part of her mind screams that this is wrong, that they shouldn't be doing this, but the pleasure overwhelms everything else as she abandons herself to the sensation.
With a shaky breath, Mako closes her eyes and gives in to her desire, allowing Max to take control of their encounter. "Do it," she whispers hoarsely. "Please... I need you..." Her fingers tremble as they brush against his hardness through their clothes, desperate for the release that only he can give her.
Taking advantage of Makoto's submission, Max easily pushes her panties aside and positions his hard length at her entrance. She gasps as he thrusts roughly inside, filling her completely with his thick cock. Her cries of pleasure echo through the room, driving him even wilder as he begins to pound into her without mercy.
Her eyes squeze shut as he pierces through her tight folds, her body tensing reflexively at the intrusion. A moan rips through her lips, unbidden and needy as she arches her back in response to the fullness he brings her. "Ahh... yes..." she whispers hoarsely between gasps, her nails digging into his shoulders in an unconscious plea for more of him.
Her hips roll and thrust against his, matching his brutal pace as their bodies come together in a primal dance of desire. The pleasure coursing through her veins is intense, overwhelming; it feels almost too much to bear, but she doesn't want this feeling to end. "Faster..." she breathes raggedly, leaning into him as his thrusts become harder and deeper.
Her body quivers as the heat between them builds, every nerve ending alight with pleasure. Her fingers dig into his shoulders, her legs wrap tightly around his waist in an attempt to anchor him closer. "Oh God... Max..." she moans, a tear slipping from the corner of her eye. She's never felt this fulfilled before, not even with Kaoru; something about having Max inside her like this just feels right.
Her breath comes faster now, her chest heaving as she nears her climax. "I'm going to... I'm gonna..." But the words stick in her throat as another wave of ecstasy crashes over her, leaving her limp and satisfied in his arms. For a moment, they just breathe each other in, reveling in the connection they share despite all the years of avoiding it.
Finally, Max pulls out with a sigh and tosses aside their discarded panties. "I guess we should get back to studying now," he says with a grin, winking at her. Makoto rolls her eyes, but can't help returning the smile as they both know this isn't over yet. There will be more secret trysts between them... just as long as no one else finds out about their forbidden family desires.
