Tiff, Sarahs Sister

Another redhead was standing at the sliding door. Tiff was tall, with a slightly more angular face than her sister Sarah, but a similar body type - the proportions of a woman made for sex. She was wearing a classy little black dress that seemed more suited to a fancy restaurant than anything else and was still holding a pair of black heels dangling from one hand.

"Jesus, Sarah. I mean, is this some sort of weird Daisy Chain sex thing? I'm not that far out of college that I wouldn't have heard of this becoming a thing, am I?"

Sarah was the first of everyone to relax, and even as she spoke over her shoulder to her sister she began moving her torso up and down, sliding Matt's cock between her tits once again. "Hah, no. This is definitely new for us. Guys, I can't remember if you've met my sister, Tiff."

We all awkwardly mumbled a chorus of, "Hey."

"Don't get me wrong, girl," Tiff said. "This is all very hot, but what the hell is going on? I thought you were just having one of your usual parties, not an orgy." She took a few more steps onto the patio and looked us all over.

I had sat up, instinctively trying to hide my dick between my hands and body. Tiff's eyes passed over me, glanced at Matt, and settled on Tom and Nicole. Tom had scrambled around and was sitting on his ass, knees pulled up to his chest, and Nicole had practically lept five steps away from him, arms folded over her chest.

"This wasn't really the plan for the night," Sarah explained to her sister. "We kinda just started this Dare game and got to here. And I, for one, am having a lot of fun. Right guys?"

We all sort of just looked at Sarah in stunned silence.

"Oh, for fucks sake," Sarah scolded. "Get back to your dares or I'm handing out penalties."

Somehow, some way, the idea of penalties from Sarah overrode our logic. I unfolded and let my dick show, grasping it in one hand. Tom returned to Sarah's ass. Nicole, the last of us, slowly crawled back over to Tom and took his dick back in her hand from between his legs.

"So, you want in?" Sarah asked her sister. "You can, but to make things fair you'll need to take the next dare."

The idea of Tiff joining the game after catching us all hadn't crossed my mind. The fact that the game was even continuing seemed kind of crazy. Now, without thought, I started eyeing her in a much different light. She had lovely, toned legs and her red hair was dyed darker than Sarah's natural copper red. Her dress showed off a significant amount of cleavage and hugged her ass just so.

"Fuck it," Tiff said. "This is hot, and I had a boring ass date. Everyone here is eighteen, right?"

"Definitely," Sarah nodded.

"Then let me go change into something more comfortable and grab a quick smoke," Tiff said, turning on the balls of her feet and striding back into the house.

"Bring out a slip of paper with your name on it, too!" Sarah said.

After a long moment of silence, I couldn't help it. "We're really going to keep playing? With your sister?"

"You want to stop?" Sarah asked. "Tiff is cool, and I definitely don't want to stop here. How about you, Miranda?"

Miranda shook her head, and then looked at me. "You still want to keep going, or is this too weird?"

Matt spoke up first. "I, for one, don't want this to ever end."

Sarah laughed, and even Nicole smirked a bit. It looked like she was squeezing Tom's dick hard in her hand, practically white-knuckling it without stroking. As long as she was keeping her nails clear, Tom didn't seem to mind.

After a minute, Tiff came back out of the house almost a changed woman. She was wearing a pair of loose grey sweatpants riding low on her hips, and a black tank top that hid most of her cleavage but made it obvious she wasn't wearing a bra underneath. She also had a cigarillo in one hand and lit it as she stepped outside. She took a few puffs, eyeing us, and I managed not to shy away from her gaze - this time it lingered longer on my hand and cock.

"Well," she said. She dropped a paper with her name on it in the bowl on the table. "If I'm in, I'm in. It's my turn to take a dare then? Who's giving it?"

"Me," Nicole said, and she let go of Tom's cock. "I dare you to take over this dick. And, uh, blow it, I guess."

Tiff shrugged casually. "Sure, looks like a nice cock." Nicole stood and practically scampered away from Tom, while Tiff took another hit off of her scented cigarillo and then blew the smoke over Tom's dick. It was... weirdly artistic and erotic, and I tried to pay attention to anything other than that thought. Tiff knelt down and grabbed Tom's cock casually, pulled it further out from between his legs - he was bent over again so his face could get pressed between Sarah's ass cheeks - to the point it looked like he had some absolutely weird tail. Tiff then leaned down and took it into her mouth.

"Oh, fuck, finally," Tom groaned out, raising his mouth from Sarah's ass. "That's fucking great."

Tiff sucked him down a few times, then popped her lips off and took another drag of her smoke, before leaning in to suck him again. She rested her smoke hand on his ass like it was the most casual thing in the world.

Nicole had come back to her chair next to the swing you were sharing with Miranda. "I never, never want to touch him again," she whispered harshly. "God, I feel gross."

"Isn't that a bit much?" Miranda asked.

"It's the exact amount I feel," Nicole said.

"Why were you so interested in playing the game if you hate him so much?" Miranda whispered back.

"I didn't know he was going to stay," Nicole chided. "I wouldn't have s-" She stopped, and looked down at my cock again. Considering I was sitting between the two girls, they'd been talking around me. "Never mind. It's fine."

What the fuck is going on? I wondered. I was relieved for Nicole... or about Nicole... or something. But I was still trying to wrap my head around the way I was seeing her now. More importantly though, and something that the others may not have considered yet, was that adding Tiff to the game meant things might change. She didn't know the dynamics yet, didn't know that there was a sort of partnering going on. Didn't know Miranda and I, or Sarah and Matt, were moving towards each other. That Nicole and I were best friends.

She might be a boulder getting thrown into the pond that Tom was already messing up. Things could get messy.

Not to mention the growing rivalry between Nicole and Sarah. The redhead had been pushing Nicole's buttons, and I had no doubt Nicole wouldn't hold back on Sarah either.

Fuck. I should stop this. I should stop this before things get out of hand even more than they already were.

"You gotta pull a name, Tiff," Sarah told her sister.

Tiff popped off of Tom's cock again, flicked the ashes from her cigarillo and then put it out in an empty glass on the table. "Sounds good," she said. She pulled a name quickly. "Which one of you guys is Tom?"

"The one you've been sucking off," Sarah replied.

"Oh, nice," Tiff grinned. She was holding Tom's cock with one hand and gave him a few tugs. "And from the looks of things, he's currently also giving you a rim job, Sarah?"

"To be fair, it is a difficult position for him," Sarah said.

"Alright, well Tom, you can pull your face out of my sister's ass," Tiff said.

Tom raised up, stretching his back and adjusting his dick. He gave Sarah's butt a smack, which just made her loose a teasing, "Ooh!" An exclamation that had Matt frowning.

Tom turned to Tiff. "What you got for me?"

Tiff's grin looked... well, mischievous might have been slightly too small a word. "How about you get in close to my sweet sister? Sandwich your dick between those pasty thick buns like a hotdog, and give her a reach around."

Tom's face lit up. "Awesome!" he said, then grinned at the rest of us. "Finally, someone who is fun." Tom waddled forward on his knees, and I couldn't help but notice that Sarah helpfully stuck her ass out to him even while she was looking Matt in the eyes and using both hands to titfuck him and tweak her nipples. Spreading Sarah's cheeks, Tom pressed his dick vertically between them and began a thrusting motion, grinding himself into Sarah.

"Now the reach around, hunk," Tiff prompted.

"Right," Tom grinned. He reached around Sarah and pressed close to her back, and Sarah cooed as his fingers found her pussy.

This, I quickly noticed, put Tom's face hovering just over her shoulder... looking right at Matt's naked torso, and Matt's dick getting titfucked less than six inches from him.

"Dude, stop staring," Matt said.

"I'm not!" Tom said. "It's- I have to do it like this. You stop staring at me!"

Tiff laughed. Miranda and Sarah both chuckled. Nicole and I couldn't help but snicker, even if I felt just a little bad for Matt that he, and Sarah, were getting wrapped up with Tom again.

"Tom," Sarah moaned, getting into being pressed between two guys. "It's your turn, babe."
