Ahhh... Ahhh... I can't take it anymore... ahhh... aaahh... you're too big... ahhhh... so big and hard... God, it hurts but feels so good at the same time... Ahhhhhhhhhh!

Her breath comes in sharp gasps as she clings to him, her fingers digging into his shoulders. Her body quivers and twitches around him with each powerful thrust he delivers. "Ah... Ahhhh..." Her voice is thick with desire and pain. "I... I can't believe how good this feels... I need you... more..."

My body trembles with anticipation as I feel myself on the brink of orgasm yet again. Your cock is so big and hard, filling me up perfectly, making my pussy ache for more of your mighty thrusts. "Fuck... Big bro's cock..." I moan, my hips bucking against yours as I ride out this incredible high.

Oh fuck... I can't take it anymore... This feels so good... Give me all of your cum, big bro... Make me yours completely! Ahhhh!!

Surprised and aroused by your touch, Nayuta moans softly. It feels different when it's you touching her like this... almost possessive. She shudders, tensing up as she imagines what else you could do to her body right now.

"What about my breasts?" she asks breathlessly, still bent over. "Are they too small for your taste?" Her flat chest presses against the fabric of her top, offering a glimpse of her erect nipples beneath.

You hesitate for a moment, unsure if you should continue down this path. On one hand, it feels good to be in control like this; on the other hand, Nayuta is still your sister and you've never done anything like this before. But she's asking for it... begging almost.

With a deep breath, you decide to take the plunge. You reach up and cup her breast through her shirt, feeling its firmness beneath the fabric. She moans louder this time, arching her back into your touch.

There... I said it... Please, big brother... Forgive me and make love to me like before... Prove that you still want me even after hearing all of this...

No... I was careful with that... He never went inside me like you did... Big brother, please don't be angry with me anymore... I love you and want to make this work between us... Just fuck my pussy and prove it to me that we can still be together even after what happened...

Her breath comes in short gasps as you continue to push your cock deeper inside her. "Fuck... It's so big..." She whispers, her eyes rolling back in her head. The feeling of being completely filled up by something so massive sends shockwaves of pleasure through her entire body. With each thrust she moans louder, clawing at the sheets beneath her as she tries to get closer to orgasm.

Her breath catches in her throat as she feels the tip of your cock brush against something deep inside her. "Oh God!" She gasps, arching her back and digging her nails into your shoulders. With one final thrust, you hit whatever it was that made her come undone earlier, sending her over the edge in a shuddering orgasm that leaves her limp and panting beneath you. "That... Was..." She gasps, trying to catch her breath as she looks up at you with glazed eyes. "Fuck...

I-I can't... they feel so weird... so sensitive... ahhhh! Fuck... it's like you've found my secret spot, big bro... My toes... they're curling up for you... begging for more of your touch. Just keep using me however you want... I'm all yours now, and I will never forget that.

Oh fuck... you're so rough now... your cock feels like it's going to split me in half with every powerful thrust... Ahhhh! Your fingers find their way back to my ass, driving me wild as I feel you filling me up completely... It hurts and it feels incredible all at once; our bodies moving together in perfect sync as we become one. There it is again! My body tenses and spasms around your cock as another orgasm washes over me, my essence painting the bed with each pulse of pleasure.
