Kristen eventually stops walking, and you hear muffled voices from outside as she talks to someone or other outside of gym. For her, it's nothing more than the waiting period before the students from the last hour are dismissed and she can head inside. For you though, the sensation is as profound as it has ever been. Every gentle shift in her position causes you to twist and stretch with her, pressing yourself to her in new and interesting ways. You hardly hear the voices outside in the light, ever from Kristen or anyone else. They're not important to you anymore. All your concern is for Kristen, your owner, and a goddess.
Eventually she starts to move again, then stops walking. You can still feel her body shifting a little though, particularly through your elastic wrapped around her waist. Then, in one quick moment, her jeans are pulled down around you, and you're bathed in light again. Looking up, you can see her upper body, and you watch as best you can as she replaces the bra with something tighter and more useful for running in.
And its not just Kristen you can see, either. From the material behind her, you can see the inside of the locker room, the room tightly packed with girls in various states of undress, many of whom were quite attractive. Oh, you'd dreamed about what it would be like to see the inside of this place. But as attractive as the other girls are, none of them seem quite as interesting to you as Kristen is. She pulls on a shirt, covering up those glorious breasts of hers... but you're hardly concerned. The next, you feel her hands about you, adjusting your elastic about her and correcting the way you've gradually started to rise on her after the day's worth of activity. You love the feel of her fingers on your soft fabric, the way you know she's thinking about you. But as quickly as they come, her hands are gone, pulling up a pair of gym shorts around you, which quickly blocks out the light.
As Kristen walks off to class, you feel the gentle swaying of her hips, gently stretching some areas of you while allowing others to hang looser, and causing her pussy to gently rub against you. She stops for awhile, then starts moving again. Her movements are different this time, though. You feel her leg muscles tighten and contract in unusual ways, and feel yourself pulled this way and that as Kristen goes through her warm-up stretches. Man is she limber. You feel her pussy stretching as her legs do, and occasionally you're pulled deeper inside her, only to be fixed by a quick stretch the other way or one of her fingers pulling on your elastic when nobody's looking. She starts running next, and its nothing like walking. You're stretched and pulled this way and that with far greater speed. You can feel her skin gradually dampen with sweat from the effort of running, soaking into you with the smell of Kristen you've come to love so dearly.
This goes on for some time, but not forever. Soon enough, you find her pace slowing down again, and she eventually stops. You feel her body shift around you as she removes her top, then the rush of motion as her athletic shorts are pulled down too, and you watch as she folds them both neatly into her locker. Her hands return to you, and you feel yourself whisked down her legs with incredible speed. . You feel her lift you gently in her hands, and are momentarily overcome with the trill of her fingers running gently over your fabric, as she feels the sweat you've collected after her time in the gym. She shrugs, and you feel her ball your body in one hand, and you're tossed lightly into her locker atop her bra. You can barely see her through one of your folds as she snaps the locker closed and walks away to the showers.
