Grinding on the bike seat soaks her white shorts

After locking up and finding the gym empty, she kept her white sports bra and shorts on, climbing onto the stationary bicycle to chase the ache building inside her. The dim light and quiet made it feel safe to let go as she started to move. Leaning over the handlebars, hands gripping tight, her long hair with the little flower ornament framing her face, she rocked her hips in slow circles. Eyes fluttering shut and lips parting, the bike seat rubbed her just right through the thin white fabric, soaking her shorts as her breasts pressed forward with every grind.
