You sit in the locker room for some time, listening to the sound of muffled chatter from outside. You could understand it if you tried, but you really don't feel like putting forth the effort. It doesn't take much to entertain you, and for now, you're content to concentrate on the feel of Kristen's sweat, and the happy memories of when she'd been wearing you only moments before. You're only dimly aware of the passage of time when she's not around, so you're hardly bored. Besides... it's such an interesting feeling to be crumpled up into a ball like this, with some parts of you touching others, and some cupped gently inside the half of the bra you happened to land in.
When she returns, your elation returns as potently as before. The locker door swings quickly open, and you can see her completely naked body, a damp towel hanging from the floor at her feet. You have a moment to merely watch as she reached into her locker to reapply deodorant, then you feel her hands picking you up gently, and lifting you into the air. You see her lift you to her nose, giving you a sniff to be sure you're clean enough to wear. Apparently satisfied, she flattens you out with her hands, and you're pulled gently up her legs again.
It feels good to be back where you belong, cradling her pussy as gently as before. You feel the slight moisture of her body soak into you, causing you to stick to her skin, and feel closer to her than ever. You hardly notice as she gets dressed, soaking in the feeling of being a part of her life, and not even noticing as she pulls her rough jeans up around you, and all light vanishes
The day continues for you as Kristen's panties. She attends her other classes, but you hardly know or care about anything beyond what you can feel of her. You spend every second appreciating her body, and loving this decision.
It doesn't last, though. Soon enough, the day is winding down, and you can hear Kristen making evening conversation with her room-mate. With the soft click of her door, you feel the gentle shift of her movements that indicates she's taking off her clothes. You know that in a few seconds, you'll come off too, and end up in the hamper. You could wait there until she goes to sleep, then change back and escape, but... the more time you spend with Kristen, the more you want to become a part of her, a permanent part. You're already touching her vagina... maybe you could go a step further and see what it's like to really be part of her.
