An Anal Creampie

Claire's face was covered with a mix of spit and semen. Mia came for the third time as Ryan thrust into her tiny asshole. She gripped hard onto Claire's jiggly ass so she wouldn't collapse as she had another world-shattering climax.

Even though the box had dinged, none of the siblings seemed to care. They were lost in pleasure. Ryan seemed to be the only one even remotely in control of his faculties and he was on the verge of cumming. Faster and faster, he thrust into Mia' delicious ass. He could hardly believe that she felt this good. What had started as a simple game had devolved into **** and sodomy and Ryan, for the first time in long time, felt powerful. He had his two slutty sisters, willingly bending to his desires... and it pleased them. Sure, he was thankful to the box for doing the heavy lifting, but it mattered not as he plunged deep into his sister's body. He was half certain he could feel Claire's toned chest through Mia as his gargantuan cock pushed through her and deformed her stretchy belly out. He pulsed at the thought, adjusting his angle downwards so he could feel it more. As he hilted inside of Mia he felt the tip of his cock prod firmly into Claire's abs. Ryan and Mia both moaned at the strange sensation. If he wasn't teetering on a climax before, Claire's smooth lips returning to his sweaty ball sack as if to say "feed me" got him dangerously close. He paused his thrusting for a moment as his cock pulsed in satisfaction, spurting a tense burst of precum inside his twin sister's accommodating asshole.

Mia liked the feeling of her brother's cock as it tensed up inside her. Even though her brother stopped thrusting, she couldn't help but rock her hips back and forth along the massive log that was filling her body so perfectly. When he tensed again and groaned, Mia knew what was coming. She had spied on him before.

She didn't know the date, but the memory had been burned into her mind. Ryan laid back on his bed, one hand holding underwear, her used panties, to his face. Eyes closed, he jerked himself off to the smell of her vaginal fluids. She thought he was big back then. Little did she know just what was possible. She knew it was wrong as she twirled her fingers around her clit, letting her soaked pussy leak into her panties. She never told him about it. She stifled her moans as she came that day.

Now she screamed full **** as her brother burst the most massive load inside her. It was an onslaught of semen that poured into her, each pulsing wave pulling her deeper and deeper into pleasure. She lost control of her body. Even though she could feel everything, her shaking legs, her squeezing insides, her belly inflating against her sister as she filled with cum. She slumped against the couch, slipping a long, long way forward off Ryan's cock before settling against the heat of Claire's body in a jittering, sufficiently ass fucked mess.

It was only a moment that Claire had to ponder why Ryan's cock had grown so much before it smacked her in the face and the final spurts of orgasmic spurts of cum from Ryan's cock and a fountain of semen from Mia's asshole started coating her face. She opened her greedy mouth and licked the most delicious white snack from her brother's tip before realizing that she didn't want any of the semen dripping down her sister's taint to enter her pussy and get her pregnant. After hoovering up Mia's crotch, she only paused a moment to consider whether it was appropriate before her addiction won out and she stuck her tongue deep inside Mia's asshole.

Ryan fell backwards on the floor and just watched Claire in all her lust, disbelieving that this could all be happening. That was the most incredible orgasm he had ever had and now he got to see the post-credit sequence. He found it incredibly hot. So did his cock, as normally at this point his cock would be slumped against the ground like him, but instead it seemed to be watching the show. Mia finally found her self and anchored herself up on her sister's legs, letting the cum pour down like dispenser into her sister's mouth.

When after a prolonged rimming Mia's asshole seemed no more fruitful, Claire stopped and meekly, "Mia, you okay."

Mia chuckled, "Yeah. That's a silly question. Of course, I'm okay. I was kind of enjoying that." Mia got off of Claire and they faced each other on the couch.

"I just shouldn't have done that... any of that." Claire responded, even though her face spelled remorse in she couldn't help but scoop the remnants of the shameful smeared mask that adorned it into her mouth.

"I think we are way past that. I mean look at what just happened." She motioned around, highlighting Ryan's tree trunk cock and the girl's still distended bellies full of cum. "Look at us. We're now all just sweaty messes, pleasuring each other for a box."

"But what you did was because of the box... what I did was because I was horny."

Mia placed a finger on her sister's mouth. "Raise your hand if you are horny." The three siblings rose their hands in unison. "See?" She hugged Claire and Ryan came over and wrapped his arms around the two of them. They held each other for a long time in silence, letting go only when it felt right. "Claire, the box made me lust for Ryan, but I lusted for you too... I'm glad you want to protect me. I know that this is not normal, but we're all human. We all lust. And I'm glad you and I made each other feel good."

Claire just said, "Thank you," and leaned in for a kiss on the cheek, a tender one full of thankfulness. What Claire didn't expect was Mia kissing her back on the lips. A few pecks evolved into open mouths, wet lips, swirling tongues, arched necks, and sweaty bodies brushing against each other.

A tender moment became intimate and Claire felt it before Mia pulled away and finally said, "Don't be ashamed of that feeling." Mia smiled ear to ear and Claire smiled back and the two couldn't help but giggle at their shared moment.

"Umm... ladies," Ryan interjected. "Want to continue the game?"

"Sure," said Claire before sauntering over to pick up the card that the box had designated for her.
