She's riding you hard now, bouncing up and down on your cock like it's a seesaw. Each stroke makes that wet spot grow bigger and more vivid. You pound into her, making her entire body rock back and forth. Every time you hit her sweet spot, she lets out an involuntary cry of pleasure, which blends seamlessly into her continued muttering.

Your orgasm hits you hard, and you explode inside her. She feels every pulse of your hot cum as it fills her up, and she lets out another moan, quieter this time, but still audible enough to suggest that she's enjoying the sensation. Her body tenses and shudders as she reaches climax along with you, milking your cock one final time before going limp on top of you.

Panting heavily, you collapse onto the mattress, spent from your exertions.
