Betty's heart races as she bounces, the trampoline's springs creaking in sync with her breath. Her fingers dip deeper, feeling the wetness coating her inner thighs. She imagines strong hands gripping her hips, another body bouncing with her, their sweat mingling. The fantasy fuels her, her pussy clenching around nothing, craving a thick cock to fill her. She comes with a cry, her body convulsing, juices soaking her panties, the trampoline slowing to a halt as she catches her breath.
