As Sia's orgasm approaches, her body tenses and her breath comes in short gasps. She leans forward, bracing herself on your shoulders with one hand while using the other to fondle and stroke your cock in perfect rhythm with each thrust of her hips. The pleasure is overwhelming...

With a loud moan, she comes, her body shuddering violently around you as wave after wave of intense ecstasy washes over her. She's so tight... so hot... It feels incredible.

Her orgasm seems to go on forever, leaving you on the brink of your own release. Finally, she collapses forward onto your chest, gasping for air. "That was... amazing," she pants.

You nod in agreement, unable to form a coherent sentence. With one last thrust, you feel yourself erupt inside her, filling her up with your hot seed as you both moan and shudder together.
