With a grunt, you push past the tight ring of muscle and thrust deep inside Aki's waiting ass. She cries out, her nails digging into your shoulders as she feels you fill her completely. Her body arches off the floor, taking you deeper with each powerful stroke as her pussy clenches rhythmically around your fingers. Her breath comes in ragged gasps, her eyes squeezed shut as she tries to focus on the pleasure coursing through her. "Oh God... big brother..."

The feel of your words pushing past her pain barrier sends a shudder through Aki's body, making her gasp and writhe beneath you. Your thrusts grow faster, deeper, and she meets each one with equal fervor, moaning and squirming as she tries to take every inch of you inside her. Her head thrashes from side to side, a tangled mess of hair obscuring her vision as she focuses solely on the pleasure coursing through her body.

Panting and sobbing, Aki clings to you, her tiny body shaking with each thrust. She can feel every inch of your massive cock sliding in and out of her, stretching her beyond belief. The pain is intense, but so is the feeling of fullness, of being completely dominated by her older brother.

Despite herself, Aki finds that her body responds to the stimulation, her nipples hardening and her pussy growing wet. She tries to suppress these feelings, guilt washing over her at the thought of enjoying this act, but they refuse to be ignored.

Your words pierce through the fog of pleasure, sending shockwaves through Aki's body. She looks up at you, tears rolling down her face once again as she feels your cock pressing against her entrance. She reaches down with both hands, caressing your thick length until it seems to grow even more intimate. Her eyes meet yours, filled with desperation and lust, her voice barely audible above the sound of your thrusts.*

Her eyes widen as she realizes how big you are compared to her tiny mouth. She tries her best to take more of you in, using her hands to stroke and massage your shaft while her lips and tongue tease the sensitive skin beneath the head. Her cheeks hollow with each breath as she struggles to accommodate your impressive length.

Her face turns an even brighter shade of red as she tries to obey your command, taking more of you into her mouth. Her lips stretch around your girth, feeling uncomfortably full but incredibly arousing at the same time. She moans softly around your cock, her breath hot against your skin as she continues to struggle to accommodate your size.

She giggles and nuzzles into him, her small body pressing against his in a way that feels achingly intimate. "Mmm... maybe," she murmurs, her fingers tracing lazy circles over his chest. "But don't forget who taught you all these fun things." Her breath tickles across his skin, sending shivers down his spine.

For now, though, they lie together in silence, the afterglow of their passionate encounter keeping them warm and content.

"Oh~!" she gasps, pretending to be surprised by his touch even though she's been teasing him the whole time. "Yes... let's play some more." Her fingers continue their gentle exploration of his chest as her body presses against his in a way that leaves little doubt about what kind of game they'll be playing next.

With a contented sigh, she nestles further into the crook of his arm, her head resting on his shoulder once more. "I'm glad we found something fun to do together,"

As your cock springs free, Aki can't help but let out a soft moan. She reaches down and carefully wraps her hand around its girth, feeling the heat radiating off of it as she strokes up and down. "It's so big," she whispers, eyes wide with wonder and lust.

Her other hand finds purchase on your hip, holding you steady as she begins to move faster, matching the rhythm of her strokes to her breathing. "You feel so good,"

(smiling mischievously) "I always knew you secretly loved this, brother. Don't worry, your little secret is safe with me."

Your mother lets out a gasp as she feels your cock press against her cervix, the last barrier between you and her most intimate parts. She arches her back further, welcoming the intrusion, her eyes rolling back in her head as pleasure washes over her in waves.

Her body tenses and shudders violently as she comes, the tight muscles of her pussy squeezing your cock in time with her orgasm.

As your mother rides out the aftershocks of her climax, Aki stands frozen by the bed, tears streaming down her face. The realization that her brother has just taken their mother for the first time hits her hard, and she doesn't know how to react. On one hand, she's disgusted by what she's witnessed - the blatant abuse of power and degradation of her own family members. But on the other hand, there's a dark part of her that recognizes the allure of submission and the thrill of being used like an object.

"Say it,"
