My twin s****r, Britney, plays on the varsity volleyball team at our private high school. We are both 18 years old, finishing up our senior year. Britney is 5 feet 4 inches tall and has long, light brown hair with faint blonde highlights in it. She has beautiful bronzed skin from frequent trips to the tanning bed, as well as several hours spent sunbathing in her skimpy bikini on our back porch. She has large, beautiful, D cup breasts that hang proudly from her chest. Even in a sports bra, it is nearly impossible to contain them. She had a toned stomach, thanks to her volleyball workouts, but a large, firm ass and thick toned thighs. I cannot even begin to describe how amazing her ass looks in a pair of ultra short, skin tight, black, volleyball shorts. Even though most of the girls on the team don't wear anything under their volleyball shorts, Britney always wears one of her ultra skimpy, lacy cotton thongs. I know this, because I can always see the thong line through her super tight shorts.

Today is the day of the state championship volleyball game. I'm sitting in the bleachers of the gymnasium next to my mother and best friend Adam. The game is nearly over, and the girls look tired, and unbelievably sexy. It's hot in the gymnasium and the girls are pouring with sweat. Britney looks exceptionally drenched. Her hair is so wet with sweat it looks like she just came out of the shower. Her shirt is completely damp with sweat, and I can even see damp patches around her crotch and ass on the black spandex shorts. Beads of sweat cover her face, neck, arms, and thick thighs. I can only imagine how completely soaked with sweat her tiny cotton thong is.

Needless to say, I have an incredible thong/panties fetish. Living with two beautiful, sexy women (my mom and my s****r), I am able to constantly feed my insatiable hunger. They are both always leaving their dirty, worn panties all over the bathrooms. The filthier the better. I love a thong filled with cum, sweat, piss, shit, etc. I like them as dirty and smelly as possible. I love nothing more than to find one of their dirty thongs, bring it to my nose, and smell it while rubbing and jerking my hard cock to images of my beautiful mom or s****r. I will often lick it or suck on the cotton material, trying to taste as much of the sweat and cum and piss as I can. Thankfully, my best friend Adam, shares in my immense fetish. We have spent countless hours in my bathroom with our shorts around our ankles, a pair of filthy panties held to our noses, jerking our long hard teenage cocks.

I happen to know that the thong my s****r is currently wearing during this volleyball game, may in fact be the nastiest, filthiest pair of panties I will ever have the chance of smelling and licking. It has become a ritual to go into the bathroom after my s****r has finished showering and find whatever pair of panties she had worn that day. But over the last few days, much to my dismay, there were no panties in the bathroom when I went into search for them. One night, I overheard a phone conversation my s****r was having with one of her teammates in her room. Apparently, the volleyball team is a bit superstitious. They decided, at the beginning of the volleyball tournament, that they would all wear the same clothes throughout the whole tournament, and wouldn't wash them either. That means, that for the entire two weeks of this volleyball tournament, my s****r has been wearing the same, smelly, disgusting thong the whole time. I know for a fact that often times, because the girls stay so hydrated during games and don't have time to make it to the bathroom, Britney will pee a little bit in her panties. I know this because the thongs I steal and sniff after volleyball games always have the most yellow stains and the strongest scent of warm piss. As I sat and watched the swear pour down her back into the crack of her ass held in those tight black shorts, I imagined finally being able to sniff and lick the greatest thong of my life. As I daydreamed, I was aware of my slowly hardening cock. I looked down and saw that I had developed quite a bulge in my jeans. I looked to my right, and saw that Adam also had developed a noticeable lump in his khaki shorts. We made eye contact with each other and smiled. We knew we would soon be having the greatest masturbation session of our lives.

I snapped out of the daydream by the sound of a loud buzzer going off. The game was over. My s****r's team had won. My mom, Adam, and I all stood up to greet my s****r. She came bounding overt to us, her large breasts swinging obscenely from side to side and up and down as she ran. Sweat was dripping from her hair and clothes. Her nipples were sticking out through her sports bra and athletic shirt. She gave my mother a big hug, and then turned to give me one. Her smell was intense, and intoxicating. As she mashed her large breasts into my chest and wrapped her arms around me, the side of my face got wet with the sweat from her hair. I wrapped my arms around her back and felt the damp material of her soaked shirt. The bulge in my pants pushed against the thin material of her spandex shorts, but I think she was too excited to notice. We all headed out of the gym towards the parking lot, my mom and Britney leading the way, with Adam and I following. We watched Britney's ass as it swayed to and fro before us, with the shorts riding up into her crack showing the bottom of her ass cheeks. She was talking very fast to my mom and using excited hand gestures while she described some of the plays from the game. When she would life her hands up, her shirt would lift up and I could see the hot pink string of her nasty thong had come out of her shorts. My cock was getting so hard, and I'm sure Adam's was too.

When we got in the confined space of the car, the pungent smell really became intense. On top of the stink that naturally accompanies a hard fought volleyball game, the smell of her filthy unwashed clothes multiplied the stench significantly. Mom was driving, Britney was in the passenger seat, and Adam and I were in the back seat sitting right next to each other. Very discretely, we had both starting rubbing our hard cocks over our jeans. Britney started complaining about how badly she needed to go to the bathroom. Apparently she had been chugging a lot of water, and hadn't gotten a chance to pee yet. She was fidgeting a lot in the front seat, clearly trying to hold in the flow. Adam and I kept stealing glances at each other and our cocks before refocusing straight ahead. My mom kept telling her to hold it, and that we'd be home soon. As the ride continued, we heard a faint, small farting noise erupt from Britney's seat. My mom looked at Britney with a quizzical glance. Britney said, she REALLY needed to go to the bathroom. She'd been holding everything in all game. God, this was go fucking hot. The smell of her fart began to waft to the backseat, which only made Adam and I rub our cocks harder. We knew we would feast on this thong that would certainly be completely vile at this point.

We finally parked, and Britney got out of the car quickly and started heading to the house. Her ass jiggled as she ran. The back of her spandex shorts were much damper than before, and we could definitely see a small yellow trickle of liquid running down her thigh. I don't think she had peed in the car, but she had definitely released a little urine as she had gotten out of the car.

Britney rushed straight to the bathroom. Adam and I headed to my room to wait for Britney to finish up in the bathroom so we could go look for our treasure. I closed the door behind us, and then turned to Adam.

"Dude, I'm so fucking hard right now."

"I know, man. I practically came in my pants smelling Britney's fart and thinking about that nasty thong," said Adam.

"Me too dude. This is seriously like, the hardest I've ever been. Come feel this shit," I said.

Adam walked over to me and put his hands over the bulge in my jeans. I'm not gay at all, and neither is Adam, but the pressure on my cock from his hand felt so good at that moment.

"Damn dude. You really are hard as rock. But feel mine. I bet I'm even harder," said Adam.

I reached over and felt Adam's cock through his khakis. I gave his cock a squeeze and heard a moan escape from his lips.

"Man, I would give anything to feel your s****r's hot mouth wrap itself around my cock," he said.

"What I really want to do is, bend her over before she gets in the shower, and stick my nose right into her filthy smelly asshole," I said.

The conversation had gotten us really turned on. Subconsciously, we had both started rubbing each other's cocks over our pants really hard. Just as I began to contemplate unzipping the zipper on Adam's khakis, we heard a loud scream from across the hall.

Adam and I ran into the hallway to see what the commotion was about.

"MOM! What the fuck! There's no toilet paper! And why is the water not working!," screamed Britney from the hallway.

Britney was still covered in stinky sweat. She still had her volleyball uniform on, but it looked like she had tried to pull her shorts up in a hurry. She hadn't pulled them all the way up in the back, and her sexy pink thong was sticking out a lot. She angrily marched down the hall to the kitchen to confront my mother. Adam and I peeked our head in the bathroom for a brief moment. It reeked in there. Britney must have just taken an enormous shit. Because the water wasn't working, she clearly hadn't been able to flush it. The smell was unbelievable. Just imagining such a beautiful, sexy girl like Britney doing such an intimate act was enough to nearly put me over the edge. But after getting a good strong whiff, Adam and I hurried to the kitchen to hear the conversation between my mother and s****r that was about to transpire....

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 s****r.

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 s****r'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 s****r argue. I looked over to him and mouthed the word, "soon." He looked back and nodded with a smile.

"Fine!" my s****r 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 k**ding me b*o? 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 s****r's favorites. The bright pink has turned a paler shade after much use and many trips through the wash. As I said, my s****r 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 s****r 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 s****r'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 s****r wearing this thong over her thick, tanned ass.

I started to think about what went through Britney's head when she wore the thong. Did it make her feel sexy? When she got dressed in the morning, did she just stare at her beautiful sexy, toned, tan body in the mirror, with only this tiny little thong to cover her most intimate area? Did she stare at her large full breasts that hung down form her chest, and realize how fucking hot she looked? Did it make her feel dirty to know that she was wearing panties filled with her own sweat, and piss, and cum? Lost in my thoughts, I almost didn't realize that I had unzipped my pants and was now stroking my hard cock.

"Dude, I gotta smell that thing."

Adam jolted me out of my daydream. With both of us openly stroking our dicks with one hand, we walked towards each other. I held the thong up in the air, and Adam and I, standing less than a foot away from each other, both leaned forward to smell the filthy panties. We both put our noses into the material, with only the thin cotton separating our noses from each other. Our cocks were probably only a few inches from each other. Then, we each inhaled deeply. The smell was unbelievable. As we inhaled the sweaty smell, I though about the hours of exertion Britney had put into the thong, with all the sweat accumulating down in the volleyball shorts covering her ass and pussy. However, the smell of the piss and shit is what made me want to cum right then and there. Piss and shit, associated with an ugly, fat woman, or a guy, does nothing for me. That would repulse me. But knowing these bodily fluids were coming from a goddess like my s****r got me so fucking hot and bothered. I thought about how amazing it would be if I could kneel down behind Britney, peel down her tight shorts and thong, and just bury my nose into her dirty, smelly asshole.

Adam took a step back.

"Dude, you know I'm not gay right" he asked me.

"Yea of course man. I know how much you love chicks. You're always trying to smell their panties, especially your moms."

"Right. So I wanna ask you to do something, but don't think I'm being gay or anything."

"OK," I responded.

"Dude, I'm so fucking hard. I can't stop thinking about your smoking hot s****r in this tiny little fucking thong. I'm trying to visualize her stroking my cock or wrapping her hot lips around it, but it's hard to do, since I know my hand so well. So...would you...like, wrap those panties around my cock, and stroke it? And I could pretend like it's your s****r doing it? And our skin won't actually be touching. Cause the thong will be in the way."

I know most of you cynics out there wont believe it, but Adam and I really aren't gay. But sometimes, when you're caught up in a super fucking erotic moment, like we were at the time, the taboo nature of tings makes you do things you wouldn't normally do in a less aroused state.

"Sure dude. Only if you return the favor," I responded.

With that, I took the filthy, shit and piss filled panties and wrapped them around Adam's hard tool. Even though the damp panties, I could feel the heat emanating off his cock. I had jerked off in front of Adam tons of times, and felt his cock over his pants, but I had never felt another man's cock so directly before. With his eyes closed, Adam made a moaning sound as I began to stroke his cock with the thong. Thinking about the dirty panties, Britney's shit still in the toilet, and the way Britney looked covered in sweat in those tiny spandex volleyball shorts during the game, I started to stroke my own cock in rhythm with stoking Adam's. I began to stroke faster and faster, getting more and more turned on, getting closer and closer to cumming, when all of a sudden I heard,

"What the fuck are you two doing!?"

I immediately let go of Adam's cock and took a step back. Britney was standing in the doorway, still wearing her dirty, tight volleyball shorts and sweaty uniform top. Her face was red and she looked pissed. With all the excitement, we must not have heard her come in. Adam and I stood there frozen, with our hard dicks sticking out of our shorts, and Britney's piss and shit filled thong still gripped tightly in my right hand.
