Her body shudders and convulses as she comes hard in your hands, her legs giving out beneath her and her pussy squirting wetness all over the floor. Her voice is muffled against your chest as she cries out in pleasure, each moan sounding more desperate than the last. She clings to you tightly, unable to believe how good it feels to have her little slit filled up like this. "Nyah... nyaa... big brother... I'm..."
I pull out my absolutely insanely massive cock and put it in her mouth
Her eyes widen with surprise when she sees how huge your cock is compared to anything she's ever seen before. She hesitates for a moment, unsure if it will even fit inside her mouth, but the primal urge to please you overpowers any fear or doubt. Tentatively at first, she wraps her lips around the head of your cock and begins bobbing her head up and down, taking as much of you in as she can.
