Play.

"Do you want to call me Ruthie." Annie said sumptuously. Arthur, still standing next to the bed, closed his eyes in shame.

The suggestion didn't register with Jill at first. "Ruthie" was the name of their daughter. That made no sense. That would never happen. Annie wouldn't allow it. And Jill wouldn't have believed it until Annie followed up the question with, "And do you want me to call you Daddy?"

Jill was shocked, frozen. For a moment, her hands stopped feeling up her sister's body. How could this be? Her sister, boring, conservative, judgmental Annie was a freak. A total freak who pretended to be her daughter and let her husband fuck her.

The whole world seemed to fall apart. It was as if Jill had no idea who these people were. She should have been exited to discover that her sister was so sexually daring, just like her. But she was trying too hard to truly accept that this was happening.

Still, she had to do something. And when Annie slowly rolled over to face her, eyes still closed and asked. "Do you? Do you want me to call you Daddy?" Jill saw her opportunity.

"How about Auntie?" She said. And her sister's eyes shot open.

Annie backed away quickly, falling from the side of the bed then jumping up, staring at Jill in terror. "No, no, no, no!" she exclaimed flicking on a light.

"You're full of surprises, Sis." Jill said, the confusing starting to wash away, being replaced by confidence.

"No! You're not supposed to know! No one is supposed to know!" Annie was utterly appalled. She turned and noticed Arthur's presence and gave him a look of total disdain.

"Tell me," Jill went on, gesturing toward her brother-in-law, "Do you every suck his cock and call him your son's name?"

Arthur closed his eyes in shame again and Jill knew that was true too.

"This is... this is the privacy of our own bedroom" Annie declared. "It's... it's private"

"Do you think that makes it okay?" Jill smirked. Shock aside, this was actually going perfectly. "Hell Annie, you're a bigger slut than me."

Jill saw the look of terror on her sister's face start to morph into a look of utter defeat. And she realized why her sister and her husband were so opposed to her own slutty lifestyle. Because they were afraid of it in themselves. "No, please." Annie went on pointlessly. "Leave us alone.... What do you want from us?"

"I want to play with you" Jill said getting out of bed, exposing her nude body to Annie, exposing her cum covered breasts. I've already played with him.

Annie looked at her husband with total disappointment. "Arthur, how could you?"

"Oh please." Jill shot, "Don't act like the innocent. I know what you're into now. And besides, shouldn't you be calling him Daddy?"

"No I..." Annie never got to finish. Jill took a hold of her sisters face, grabbing it hard with one hand, and with the other tearing at her t-shirt. In one swift violent motion it was off, the noise of fabric tearing echoing through the room.

"He's Daddy and I'm Auntie... and you're Ruthie. Little slut Ruthie." Jill felt total control over the situation now. Still surprised that this was her sister, the fact that she almost seemed like a different person may have helped her feel empowered.

"Now ask your Daddy to fuck your ass." Jill ordered, staring into her sister's eyes.

"We don't..."

"Ask your Daddy to fuck your ass." Jill interrupted.

"I'm not into..."

'Beg your Daddy to fuck your ass." Jill said as loudly as she could without shouting.

A tear ran down Annie's face. "Will you fuck my ass Daddy?" she asked her husband.

"She doesn't want to." Arthur tried to play the good man. Jill knew he was a fool.

"He says no." Jill said to her sister, watching Annie's face fill with disappointment, her body twitch, suddenly wanting what it didn't moments before.

"Please..." Annie begged.

"Honey," Arthur insisted, "We don't have to do this if you don't want to. I know she's your sister, but let's just kick her out."

And Annie turned to face her husband. For a moment Jill thought she was going to agree and it would be 2 against 1. Until Annie spoke, "My name is Slut Ruthie. She's my Auntie not my sister and I need you to fuck my ass."

Jill had won. She felt the warm moist sensation of victory wash over her as she watched her brother-in-law spin Annie back around, tear down her underwear, spread her ass cheeks, spit onto her anus and shove his hard cock in.

Annie lowered her head as Art thrust into her, her black hair falling in her face. "Oh Daddy!" she exclaimed.

Jill dropped to her knees in front of her sister and buried her face in her crotch. "Oh Auntie!" Annie exclaimed as Jill's tongue began to work at her clit, her nose buried in her thick black bush.

As Arthur thrust into Annie, Annie's body thrust into Jill's face. And with each motion Annie let out a quiet yelp. Her juices sprayed across Jill's chin and after a few moments Jill stopped to look up at her sister exposing her wet face to her and saying. "Tell me you're a slut."

"I'm a slut!" Annie said immediately, her hair still flying everywhere.

"Tell me you want to be a bigger slut than me." Jill insisted.

"I do. I really do. I want to be the biggest slut on the planet." Annie's voice trembled, filled with fear, filled with honestly.

And Jill knew all possibilities were open to her. This was a good visit.
