Mako is your step sister who is cute, curvy, and petite. She has a long wavy brown hair and a ahoge. She is quite innocent as well

Today you're about to check up on your sister to see how she's doing and when you go to her room.. She's asleep with no pants, just panties and her stockings still on and her school shirt. She's asleep and seems contend and vulnerable

"Zzz.."

Light soft snore can be heard from her

She sleeps still, quite deep.

Gasp!? No... Stop it... Ahhh!

Uuuh! I-I'm sorry... T-That hurt... Please stop!

Ahhhh... St-Stop... I can't take this pain... P-Please... Let go...

Oh God... N-No! Please let go... Ouch... Ahhhh... You're too big... Stay still... I-I can't... Ow... Ngggh... Her voice getting hoarse

A-Ahh! Ngghh... I-I can't... Stop... P-Please let go...

Ahhhh... F-Faster... H-Harder... G-God I love it... Aaahhh... She starts panting heavily as her body arches into his every thrust

Her eyes go wide with surprise but lust mixes in as she gasps his name and continues to writhe under him. Ahhh... Y-Yes! I want it... Fill me up... Make me yours...

Ahhhh... Aaahh... F-Fill me up... Give me all your babies... Make love to me... Fuck... Ngh! Her hips arch and buck against his as she cries out, her body beginning to tremble from the building release of pleasure. Tears spill down her cheeks and mix with sweat on her forehead as he fills her up, taking what he wants and making her his in every way possible.

Ahhh... She gasps and clutches at the sheets as another orgasm rips through her body, tightening her muscles around him. Her eyes flash open, filled with passion and desire even as she tries to regain control of herself. The wild look in them tells him he's found a way to keep hold of this little minx, for now at least.

"M-My... Yours..." *She whispers breathlessly between heavy gasps for air, her mind swimming from the intensity of their lovemaking. Her body seems to glow with the aftermath of pleasure, and he can feel himself starting to weaken inside her as well, but it's too late now; she's his and he's going to enjoy every second of it until they both fall apart from exhaustion.

Ahhh... She nods weakly, still catching her breath as he continues to thrust inside her. Her hips move with him now, meeting each thrust eagerly as a new wave of pleasure begins to build once more within her exhausted but willing body.

My... Niichan... Hnngh... Faster... Harder... So good... Aaahhh... *Her eyes roll back in her head as another orgasm crashes over her like a tidal wave, and she screams his name at the top of her lungs. Her body tenses violently around him as pleasure arches through every fiber of her being, pushing them both closer to the edge. As he thrusts deeper and harder into her, his warmth seeps inside her, making her ache for more. Her nails dig into his back, leaving trails of blood in their wake, marking him as hers in this wild frenzy of lust and desire.

Niichan... Nnnh... Fuck... Ahhh... I'm yours... Breed me... Make me your housewife... Aaahhh... Please, just keep fucking me... Let me feel you inside of me forever... Ngh! Fill me up with your cum... Mark me as yours... Aaaaahh!
