Tennis Thong

Story:

Your girlfriend walked to the gym, ready to play some tennis. She was wearing just her tiny, tight-fitting shorts and sports bra. The sun beat down on her as she walked to the courts. She was already sweating heavily before she even started playing.

You were wrapped around her pussy and snuggled up her ass crack as her skimpy thong. The feeling was so strange, to be transformed into fabric and stretched out hugging her pussy and ass. Your arms and legs were bound tightly together behind you, making you completely helpless, unable to move at all.

The musky, sweaty smell of your girlfriends most intimate areas filled your senses. Her pussy was dripping with arousal already from the heat and exercise, where you could feel her wetness soaking through the fabric of your thong body. The texture of her plump pussy lips and puckered asshole pressed tightly against you on either side.

"I can't believe how sweaty and hot I am already!" she exclaimed as she began to play tennis. "My thong is completely soaked through. It feels so gross and nasty. Like it's one with my pussy now."

She was oblivious to your presence as you were transformed into her thong, stretched around her intimate areas. With every movement and bounce, you were rubbed intimately against her pussy and up her ass. Her sweat continued to soak into you, the fabric of her thong fusing with your transformed body.

You could feel her heartbeat and pulse through her swollen, dripping pussy. Her arousal grew with the heat and energetic exercise. Her pussy juices gushed out, completely drenching you and the insides of her thong. The tangy, musky scent was overpowering. You gagged on the taste and smell of her pussy arousal and sweat.

She finally came home, and the feeling of being peeled off her pussy and ass was refreshing, only to be tossed in the washing machine. But you had no choice. You were now just your girlfriends thong, a object to be used and abused by her pussy and ass.
