Josh and Tiffany

It was my second day home on Christmas break and I headed down to the small in-home gym on the first floor to start the day off with a light workout. As I walked down the hall I could hear noise from the gym equipment and hastened my step knowing what I would find inside.

"I can't believe it," I said spotting my step-sister on the stationary bike, already working up a sweat, "I told you not 20 minutes ago I was headed down here to loosen up my leg on the bike, and you rushed down here to jump on ahead of me."

"Oh what's the big deal Josh," Tiffany said more than asked. "I figured I could finish up before you even started. I won't be too much longer anyway, just get on the elliptical."

"You know I don't like the elliptical, and you know I wanted the bike, but whatever."

I climbed on the elliptical machine and started off awkwardly as it always does until a rhythm builds. It wasn't just that I liked the bike better it also had a direct view out the window. The elliptical was a later addition to the gym and was stuck behind the bike as an afterthought.

Getting into the rhythm of the machine I was able to relax and not focus so much on the mechanics so much. I then noticed I had a better view than I expected. Tiffany's programed workout obviously had her climbing a steep hill as she was standing up on the bicycle cranks and leaning all the way forward. The thin light blue shorts she had on were soaked down the back of her ass with sweat and the outline of her panties beneath was clearly visible.

As if she sensed my gaze Tiffany called out in a breathless voice, "You'd better not be looking at my ass Josh."

"Well it's kind of hard not too, you've got it sticking right in my face. If you didn't want me looking you should have waited until I finished my workout you knew I was going to do."

Tiffany didn't reply she just continued with her workout. The grade reduced and she returned to the seat, occasionally standing to sprint. Josh could not help but notice that each time she did she pushed the the front edge of the seat into her ass and along the bottom of her pussy he suspected. She was definitely teasing him.

Josh tried to focus but it became harder and harder and so did his cock he discovered. Josh's bulge was now very obvious and he tried to think of anything else to get his raging hardon to subside. With a little effort he got it under control and just in time as Tiffany was finishing up her ride.

Josh looked down to check himself and could still see a bit of a bulge but not nearly as bad as it once was. As he looked up his eyes met Tiffany's eyes and it was obvious she saw him checking himself out. She gave a look down then shot him a smile. "It's all yours brother," she said and walked out.

Josh walked over to the bike not feeling much like continuing his workout anymore. He looked down and saw the sweat covered seat then without really knowing why he leaned over and sniffed it, inhaling deeply. Josh could definitely smell Tiffany's pussy and ass scent where it had mixed with her sweat and deposited on the seat, working in more each time she ground against it. Almost instantly Josh's cock was fully erect again and he realized he needed to get to his room. But not before one more good sniff.

Rearranging himself so his cock was held against his stomach by his waistband Josh pulled his t-shirt down over the outside of his shorts and headed back to his room hoping he didn't meet anyone on the way. Back in his room Josh quickly stripped down and grabbed his cock firmly in his fist rubbing the oozing precum around the head with his index finger. Remembering the smell of Tiffany from the seat Josh was lost in himself when there was a knock on the door.

"Yay!" Josh yelled in reply to the knock.

"Hey Josh, it's Tiff. Can I come in?"

"I was just about to get in the shower, come back later," he replied.

"I think I should come in now, it's kind of important. Please?" Tiffany asked.

"Okay, hang on." Josh grabbed an oversized bath towel and wrapped it around himself. His bulge was reduced by the scare from Tiffany and the thickness of the terry cloth covered the rest. He walked to the door and opened it. "What was so important Tiffany?"

"Well," she said looking him up and down and still clad in her sweaty workout gear, "I just wanted to say sorry for using the bike when I knew you wanted it."

"That's fine, it really wasn't a big deal."

"No? So are you happy I got to use it first?" Tiffany asked.

"Ahh, it really doesn't matter," Josh said, not really knowing what to say.

"Oh I think it does," Tiffany said walking into the room. "I waited at the gym door and peeked through the window, I saw what you did."

"What are you talking about?" Josh stammered.

"You know what you did, but don't worry, I don't blame you, I made you do it. Here hold out your hand, I have something for you."

Not knowing what to do or say Josh held out his hand and Tiffany extended her hand over his and opened her previously clenched fist letting her sweat soaked panties fall. "I figured you would like these since you gave the seat such a good sniff."

Josh looked into his hand and saw a pair of dark blue cotton panties made even darker by their wetness. He could feel the moisture and their warmth and was sure he could even smell them.

"Well go ahead," Tiffany said, "smell them. That is what you want isn't it?"

"Uh, yeah," Josh said, not really knowing what else to say as he drew his hand to his face. The closer he got, the more he could sense Tiffany's smell. Finally reaching his nose he drew in deeply. Her scent was 100 times better than the faint trace left on the seat, and that was exquisite.

"You like that don't you," Tiffany more said than asked as she reached behind her and closed the door. "You see," she said, "I kind of developed a strange fetish at college, I like it when guys sniff my dirty panties and rub them on their cocks. Do you think you could do that for me?"

"Tiff, this is really fucking strange," Josh said pulling the panties back from his nose long enough to speak, "but it is so fucking hot. Tell me what you want me to do."

"I figured you would say that," Tiffany smiled and gave one of her nipples a quick circle through her shirt with a fingertip. "That's why I spent so much time preparing. I wore those panties for two days straight rubbing my pussy every chance I got, getting them wet, then I wore them on the bike this morning to get them really wet. Do they smell good?"

"They smell awesome, good enough to eat."

"Put them in your mouth then," Tiffany told Josh.

Josh did as Tiffany commanded and instantly his mouth was flooded with a mixture of salt and sweet and muskiness.

"Come over here," Tiffany motioned as she moved to the edge of bed and sat down. "Stand right here in front of me, and let that towel drop."

Again Josh did as commanded, standing in front of Tiffany with his now erect and throbbing cock dripping precum the length of the shaft.

"Mmm, I like the look of that, I bet it tastes good. Take my panties out of your mouth and get a big drop of that precum on your finger and taste if for me."

Josh removed the panties from his mouth and cupped them under his balls with his left hand while his right index finger scooped up a big drop of precum and brought it to his lips. Josh sucked it from his finger and tasted his own juices which where almost as good and Tiffany's residuals. As Josh sucked his own juice he looked down to see Tiffany licking her own lips and rubbing herself through her shorts.

"Do you think I could have a taste Josh?" Tiffany asked. "Scoop up some more and give me your finger."

Josh gathered another pile of precum on his finger and held it out to Tiffany. Tiffany leaned forward and took Josh's finger between her lips and sucked.

"Mmm, that is good," she purred. "Now take those panties and stroke your cock with them. I want to see you cum with my panties."

Using his left hand to hold the panties below his cock Josh began to gently stroke his cock from above with his right. With each stroke more precum pumped out and spilled onto the waiting panites. Rubbing his head into this pool both his head and the panties were soon covered in his slickness.

"You do that so well Josh," Tiffany moaned as she watched while still rubbing herself. "I love how big and swollen your cockhead is, and you make so much precum. I know you need to cum soon so don't hold back on my account, I want to see it."

"Sure thing Tiff, I think it is going to be a big load, you are so hot and your panties feel so good, I am going to cover them."

As Josh's strokes intensified so did his breathing and so did Tiffany's. Tiffany now had her hand fully down the front of her shorts and was rubbing her pussy wildly. Between her breathes Josh could hear the wetness of her pussy and it proved too much for him.

"I'm cumming Tiff," he gasped, "here it comes."

"Yeah baby come for me Josh, catch it all in my panties, don't lose a drop."

Josh stretched the panties out in front of him and spurted strand after strand of hot cum into the pocket. As he came Tiffany arched back on the bed and pushed her pussy hard against her hand, grinding against it and cumming as she did. When they had both caught their breath and kind of regained their composure, Tiffany stood up and took the very full and cum soaked panties from Josh.

"Thanks Josh, that was good, maybe later we can talk about some more of my fetishes. You had better take that shower now, I need to get these back to my room," Tiffany said grinning as she looked at the panties in her hand and walked out the door.
