Something Phallic and Totally Unfair

Ryan read quickly and loudly, so all could hear, "Either keep something phallic in your ass or you can't breath until your sister cums."

"What!?" asked Claire shocked from her brain fog, her older sister sense kicking in. She gripped Mia's paling face and saw her start to gasp for air, the oxygen in her lungs starting to deplete. She jumped up and gripped Ryan's hands in hers, "You know when I thaid not to fuck Mia's ass? Scratch that. Ssstick your cock in her right fucking now!"

"Uh... I just came. I'm not really hard at the moment." Said Ryan, but before he could finish his sentence Claire was on her knees trying to shove his massive cock in her mouth. It was now a bit to big for her to fit, but she was licking and fluffing like her sister's life depended on it. And it did.

Claire knew she had to get him hard quick if there was any chance for this to work. She could tell he was shocked, too far in his head. "Ryan stop worrying and look at me." She stroked his cock and slurped at his tip as precum oozed out at a steady pace. "I love your big fat cock. *slurp* I wish you could shove this nathty beast in my fat ass. *slurp* Why don't you get real fucking hard for me? *slurp* That's what I've really wanted this entire time."

Ryan saw what she was doing and played along. "Yeah, you've been wanting my thick fat cock this whole time, huh? You whore. Tell me you're a slut."

"I'm a ssslut. Please fuck my whore mouth." Moaned Claire as she slurped at the tip of Ryan's cock head.

"You play all coy, but guess what... you're going to have to beg like Mia if you want any hope of getting fucked like the little whore you are." Ryan couldn't tell if it was his sister was meant what she said, but it was doing it for him. He was playing along as long as she was.

"*slurp* Treat me like a whore, bro. Fuck my pretty little mouth." She said as she slurped at his stiffening member, circling his tip with the piercing in her tongue.

He gripped his sister's head and rammed his cock until she couldn't take any more. Her cheeks puffed out, her mouth totally encompassed by his cock. It was a pretty little mouth, especially with his giant cock forcing it's way in. She was gagging and fingering herself as Ryan used her face.

The feeling of power over his sister felt good. Too good. He liked this new Claire. He had many wet dreams of her, but who would have thought the altruistic aspects of her would lead to her degradation? What more would she sacrifice for her siblings? The thought gave him dirty ideas; ideas that filled him with a dangerous lust. Soon he was hard as a rock inside his sister's throat, which gave more purchase as he skull fucked her, but she still wasn't even close to taking his entirety.

He released her as she gasped for air, reminding her of her sister's plight. Claire reminded herself not to get lost in her lust. She glanced at her sister slumped into the couch cushions, ass up.

"Now stick that hard dick in Mia's ass, you big ssstud." Claire stood with an uneasy wobble, high on cum, and led him towards his twin. Ryan couldn't hardly believe it. He was going to fuck his sisters ass and not only did she want it, she needed it. Her rosebud looked tiny as he parted it with the tip of his spit-covered trouser snake. Her stretchy body accommodated his size easier than he thought and the slick coating if his sister's saliva made it easy to push the head of his cock in, but it didn't take away from the fact that his cock looked comically large shoving into his twin sister's asshole.

Before he was even a couple inches, Mia gasped a long strained breath as her back arched and life returned to her body. She took several more as she steadied herself. "Oh, thank you, Ryan. You're my hero." She wiggled her ass a little, feeling the welcome intruder. She had never had sex, but had put plenty of things inside herself. She never would have thought that the thing she would enjoy the most was her brother's cock inside her ass, where she mostly avoided. Now she relished the feeling and pushed her tight little rear end into Ryan's cock until she had hilted out on him. "Oh, fuck that feels so good. I want you inside me all the time." She arched up until her face was at Ryan's and gave him a big slobbery kiss. They melted into each other.

Ryan wrapped his arm around his sister and felt a massive bulge in her mid section where his cock was basically poking out the front. If not for the condition of the game, he might have thought something was wrong, but this was damn sexy. It felt natural being like this, he started to thrust some and Mia rode along with him and they swapped spit like an unquenchable thirst drove them on.

Claire spoke up, "It thaid to keep something phallic in your ass Mia... and Ryan, not to fuck."

"Uh huh," they both replied as the twins kept fucking, ignoring their sister. Each thrust was heaven, the inevitable conclusion to the events of the game. Mia was so horned up she was on the edge of climaxing already.

"Well, I can make you stop by cumming... ssso I'll just do that." Claire needed this to stop. She did what she did for Mia, but now she knew things had gone too far. They had crossed a line. What line would get crossed next? However, she couldn't fight that the thing that was getting her hot and bothered was her two siblings fucking like animals on the couch. At least she would cum quicker, but could she live with the idea that she basically made her siblings fuck and was now getting off to it?

"You can make the condition stop." Chimed Ryan. "...but I think we'll keep going if that's fine with you. Besides, you admitted you like it. You just wish it was you." He nibbled at his sister's neck as he reamed her asshole over and over. It was crazy to see the bulge in Claire push out of her abs over and over.

"Yeah," Mia said with her tongue fully hanging from her mouth. She was loving it. "Fuck me! Fuck! Oaaaaaahhh!" She screamed as she came.

That reminded Claire of her addiction as she said, "Fuck it. I might as well enjoy it." She picked herself up and situated her face below her sister's quivering pussy as she lapped at the girl cum she wanted so bad. She had quite a view as she jilled herself on the couch. Prime seating for an absurd ass fucking.
