"The pipes froze over. So we had to shut the water off. We have someone coming out tomorrow to fix it, but you'll just have to wait until then," said my mom to my sister.
Britney was standing in the kitchen looking livid. Her clothes were still soaked in sweat and she looked hot and tired after her volleyball game. Her beautiful brown hair was tied up in a sloppy ponytail on her head. She was standing with one hand on her hip, and her shirt had lifted up a little bit on the side, exposing the string of her sexy pink thong. Her large breasts were heaving up and down under her tight uniform top.
"Mom I just played in a fucking volleyball game! I'm disgusting! I can't wait till tomorrow. And what about the toilet paper? I already....'went to the bathroom' by the time I noticed it was gone."
"Well honey, the water will be fixed tomorrow. I think you can go one day without showering. And I was heading to the store anyway. So I'll pick up some toilet paper while I'm out. You might as well go change your clothes."
"Mom I'm covered in sweat. I smell terrible. I don't want to ruin a perfectly good outfit. I'll just keep my volleyball uniform on until I get to shower tomorrow."
"Well at least change your panties sweetie. If you just went...'number two,' and then pulled your thong back up, I'm sure it's quite nasty. You'll probably start to chafe. So at least go change that."
Just hearing my mom talk about my sister's filthy thong put an extra strain in my pants. My cock was already painfully hard after Adam had rubbed it in my room. But if it was possible, it had gotten even harder. I looked over and saw Adam was rubbing the bulge over his shorts while he listened to my mom and sister argue. I looked over to him and mouthed the word, "soon." He looked back and nodded with a smile.
"Fine!" my sister screamed. And with that, she stormed out of the kitchen and headed back towards the bathroom. Adam and I hurried back to my room to get out of her way. From inside my room, we heard the bathroom door slam. Then, after a couple of moments, we heard Britney stomp down the hallway to her own room. Then, we heard the door to her own bedroom slam.
Adam and I looked at each other.
"I think this is it dude. She must have taken off that fucking thong. It must be just waiting for us in the bathroom. Are you ready to do this?" I said.
"Are you kidding me bro? I'm about to cum in my fucking pants. Let's go get that thing."
Adam and I quietly open the door of my bedroom, and tiptoe across the hall to the bathroom. We go into the bathroom, and quietly close the door behind us. The smell coming from the toilet is strong as we search for our treasure. The floor is pretty spotless. I open the closet door and look down into the fairly full laundry basket. All of a sudden, I freeze. There, sitting on top of the pile, is our treasure.
It is the tiniest little thong I've ever seen. I'm sure it used to be a brighter shade of pink, but clearly, this thong is one of my sister's favorites. The bright pink has turned a paler shade after much use and many trips through the wash. As I said, my sister is in great shape, but her ass is very large. She says it helps her play more physical in her basketball games, the other sport my sister plays other than volleyball. So as I look down at the tiny piece of pink fabric, it boggles my mind to try and imagine how she fits into this skimpy thing. I pick up the dirty thong and hold it up in the air for us both to see. Even holding it away form my face, the stench is unbelievably strong. A mix of sweat, cum, piss, and shit invade my nostrils. I look over and Adam has already released his thick hard cock form his pants. He's looking at the thong in my hands as he begins to stroke his hard meat.
The thong feels relatively heavy for a pair of panties. Clearly, all the liquids in it are weighing it down. As the liquids begin to dry and become sticky, the thong had closed itself into a tight ball. I had to peel it apart in order to get a good look at it. As I do, I start to rub my hard cock over my jeans with my other hand. First, I inspect the crotch. Britney clearly wasn't hydrated enough, because there was a dark yellow stain right in the middle of the crotch of her panties. There were white stains in the crotch as well. Maybe it was just natural secretion. Or maybe Britney enjoyed seeing her teammates in those skimpy volleyball outfits as much as I did. Who knows. I then examine the back part of the thong, which is really nothing more than a string. The string is stained brown, and I know that this little piece of cotton had spent hours wedged up in between my sister's beautiful ass crack, touching her dirty, smelly asshole. With no toilet paper, she hadn't had a chance to wipe, and I know Britney had pulled this thong back up over her shit stained asshole before going into the kitchen to argue with my mother. It turned me on so much to think about my sister wearing this thong over her thick, tanned ass.
