Karen’s boyfriend was an asshole. On her birthday he gave her a fucking dildo.

And in front of her sister too.

The bastard was so lucky he didn’t just slapped him in the face and kicked him out.

But when they got back to her place, well, it turned out it wasn’t such a bad present.

Alphonse didn’t even fuck her that night, simply using the dildo on her, holding her in place, he told her she wasn’t allowed to get her hands away from the headboard or else he would stop, and he did stop every and any moment that Karen’s hands let go of the headboard.

Eventually he fucked her to orgasm, kissing her while holding the toy deep inside of her.

The following morning he gave her a little kiss on the lips and left to work.

That day, Karen couldn’t stop using the dildo, to the dismay of her sister, who kept banging on her door telling her to be less vocal about her orgasms.

Of course Karen ignored her. And eventually, her sister left the house and didn’t come back until late at night.

It quickly became very obvious that Rachel had brought someone else home, as she moaned very loudly as the guy she had brought home started fucking her against Karen’s door.

Two could play that game, Karen thought and called her boyfriend, but he never answered.

Still she had that little gift of his.

It became a sort of competition, who could moan and be fucked louder, even if Karen only had a toy inside her to keep her company and please her.

A very good toy, but a toy none the less.

She came over and over again, listening to Rachel’s orgasm.

Both eventually tired out and fell asleep. Each with their toy deep inside them.

The following morning, Karen left the house and went to find her boyfriend. Alphonse was nowhere to be seen, but he eventually called her.

“Get your clothes off, go inside, and wait for me. In that order. I’ll be at my place soon enough.”

That was it.

But then her phone vibrated again, it was a text of him.

“Oh and send me picture outside, as proof.”

The gall of this asshole. He couldn’t just expect her to just take off her top.

Her bra.

Her jeans and panties.

In the middle of the street.

It was simply too.

“Fuck,” she moaned as she pulled out her top and unclasped her bra, “why does this turn me on so much!?” Her panties were already dripping when she took them off.

Karen took the picture making a little V sign for the camera and rushed inside.

Or at least tried.

The door didn’t open. It was locked.

She cursed and thought, right, the key. She had to find the spare first and as she did, she bent down, it was in this moment that she heard a loud whistle and felt her face turn completely red.

It took her a couple of tries but eventually she managed to get in.

Karen’s heart was beating fast, she felt shame, embarrassment, she felt her arousal dripping down her leg and…

And she couldn’t help herself.

She sank to her knees and while facing the door, she began to play with herself again, teasing and rubbing her clit, sliding two fingers inside her cunt.

Fuck she should have brought that dildo. She thought.

Karen didn’t know how long she waited there, but she had made a small pool of juices by the time Alphonse walked through the door.

He had that stupid cocky smile in his lips and leaned down to cup her chin.

“You did great,” he said, “such a good girl.”

Karen moaned to the praise.

She needed it, needed him, it didn’t matter that he had taken his sweet time, it didn’t matter that he had lipstick on the collar of his shirt. It didn’t fucking matter that he tasted like some girl’s pussy and had her smell all over him.

The fucking asshole was hers and she was going to get fucked now.

Karen’s need took the best of her and she practically lounged to suck his cock, taking him into her mouth, kissing him, eagerly and desperately sucking him until he was rock hard and ready to take her.

“Fuck me!” She demanded, “Now”

He laughed and grabbed her, lifting her easily, and pushed her against the wall to slide his cock past her pussy lips.

“You don’t make the rules here, little girl,” he said, “I’m your owner.” He groaned into her ear as he fucked her, hard, fast, making her mind blank with every thrust.

“You belong to me.” He said

“Yours,” Karen moaned, “yours!” Again and again and again.

Until she felt his cock twitch and cum deep inside her.

Karen came, grasping to hold him, any part of him, his wrists, his arms, her face against the cold wall simply drooled as he let go and let her collapse in the floor.

Satisfied, and with a droopy smile, she turned around and lazily cleaned his cock, it tasted of her, but smelled of someone else too.

“You are mine too, understand,” she said, grasping his balls, “you don’t go around breeding other girls.”

He laughed and patted her head, his fingers ran down and caressed her hair.

“You don’t need to worry about it.”

Later that night, Alphonse drove Karen back to her place, but, again, being the asshole that he was, he drove her naked and left her on the side walk.

Karen walked inside and heard the moans immediately.

Rachel was still at it, moaning as loudly as she could, had she even realized that she was gone?

Finding her way to her room, Karen noticed the arousal building up again, the need burning her cunt after being made to parade her naked ass for her neighbors to see.

She needed that stupid toy again.

But it wasn’t there.

Karen searched her room, it wasn’t with her toys, it wasn’t under the pillow where she thought she left it. It wasn’t under the bed and-

That loud moan.

She couldn’t have.

That bitch.

Karen bursted through Rachel’s room and found her sister fucking herself with the toy that Alphonse had given her. She had a face filled with such mindless ecstasy, with such intensity. It was mid orgasm.

But Karen wouldn’t have it.

She stomped her way through her room and simply yanked the toy out of her sister’s cunt.

“It’s mine!” She said, leaving her sister drooling, shaking, and with her cunt gaping open.

Karen rushed to he room and went straight to clean the dildo. She stayed a bit too long cleaning it, thinking of how hot it looked going in and out of Rachel, how hot it was when Alphonse was fucking her.

And there was a loud knock on the door.

“Well you can have that fucking toy, I can call the real thing!”

No.

She couldn’t.

Karen opened the door and stared at her sister, she was slightly taller than her, her eyes were determined. The phone was ringing.

“You wouldn’t” Karen dared her.

“Al?” Rachel said in a sultry voice, “Can you come ove again? I really miss you. And my sister is being such a bitch, not sharing her toys.”

Karen stared at her, at the phone. There was a moment of silence.

“I’ll be there in ten.” He replied and hung up.

Karen wanted to smack her, to kick her, pull her hair, but she simply stared.

“He’s mine.” Karen hissed.

Rachel simply smiled.

“I guess will finally learn to share.”

“Fuck you.” Karen said.

“Fuck you!” Rachel replied.

But neither seemed able to reach or touch the other, locked in an impasse, naked, breathing heavy and angry at each other.

Then the door opened. She didn’t know since when Alphonse had a key to their place, but Karen was happy to see him.

“Al, baby, I’m glad you are here, my sis stole the toy you gave me.”

“Alphonse, tell this bi-”

“Kneel.” He said with a big smile.

Both of them complied and fell silent.

“I thought it was time you two learned to get along each other,” he said caressing both of their faces.

“Now, since I took you earlier, I think it’s your sister’s turn, don’t you think so, Karen?”

Karen’s mouth fell open, “You bastard,” she said, “you are supposed to be mine!”

Alphonse grabbed Rachel and princess carried to Karen’s bed, there he sat down and pulled out his already half hard cock.

“You can’t do this to me!” Karen cried from where she had fallen to her knees.

Rachel grinned from ear to ear, gloating, she caressed Al’s cock and made all hard, moaning as she took Karen’s boyfriend deep inside her.

“You can use your toy,” Alphonse told Karen.

Without thinking, Karen grabbed the toy and started fucking herself, “We are going to make some new rules,” Alphonse said while groping and fucking her sister, making her moan louder and louder, “You are going to learn to share, while I’m with one, the other can use that toy to fuck herself. You can watch, or you can wait, but you are going to learn to share me, to share your toys.”

Karen tried to keep the pace.

She watched and moaned as she felt her tits, bigger than her sister’s, and mimicked their motions and reactions.

“And you are going to learn to get along, I got tired of all that drama.”

He drove his cock harder into Rachel, Karen saw him twitch

“Understood?”

Both of them groaned in pleasure and displeasure at the same time.

“Understood!?” He drove the cock harder and pinched Rachel’s nipples.

Karen pinched her own.

“YES!”

“YES!”

Both moaned.

“Yes, Master.” Alphonse groaned.

“Yes! Master!” Both said.

With that he finished and came deep inside Rachel, forcing her own orgasm, and by extension, Karen’s too.

There was a moment of silence where all of them caught her breath.

Alphonse cock, slipped out of Rachel, and he kissed her, whispering into her ear,

“Who do you belong to?”

Rachel lovingly kissed him, caressing his face, “You, Master.”

He left her and then moved to caress Karen’s face, she had slumped against the wall and the dildo was sliding out of her cunt, “and who do you belong to?” He whispered as he kissed her forehead.

Karen grumbled and muttered, “You, Master…”

Alphonse smiled and princess carried her to her bed.

“And do you know who I belong to?”

The sisters looked at each other, smiled, held hands and said at the same time, “you belong to us, Master.”
