Sharing is Caring

She set the groceries down on the counter top with a loud thud. As usual, she'd attempted the impossible feat of carrying 12 sacks of groceries up the stairs at once. Now she has a broken high heel to show for it. She sighed, pulling off the hapless patent leather shoe to look at the damage. Jack had bought her this pair of shoes. As an anniversary present.

Where was Jack? She thought. His car was in the driveway. She gave a bittersweet grin gazing at the shoe. It had been their third wedding anniversary. He'd bought her the shoes at a department store. They were absolutely not her cup of tea. But the poor guy was clueless about women, and she could tell that he'd put far more thought into buying them than he should. It touched her deeply to watch his face squirm as she opened the shoe box. She fucked his brains out for it, wearing nothing but those high heels.

What a wild night that had been. Poor guy hadn't ever really explored sexuality, and she'd been waiting anxiously for his sex drive to kick into high gear. He was shocked when she took his cock all the way down her throat, afraid he would kill her. She laughed with his dick tickling her gag reflex and pulled it out to stroke at as she reassured him that all she wanted in the whole wide world was for her hung husband to fuck all her tight pretty holes. The look on his face in the mirror as he negotiated her anal canal was priceless.

They'd come a long way in the four years since that. They'd explored each other's bodies intrepidly. Role play, bondage, toys. She was just pleased that she could channel the lessons of her misspent youth on the man she loved.

These past few months had been yet another point of demarcation. Three months ago, as they cuddled post-coitally in a puddle of his cum, she'd expressed a desire to swing. He'd been against it vehemently at first until he realized all she wanted was to scratch a bisexual itch of hers and maybe have some threesomes. Nervously, he'd gulped at the thought and the sight of his Adam's apple oscillating in his throat prompted her to hop on and ride him again. She grinned, knowing he was going to love having two women going at him. The only question left was who would be the lucky girl.

She put away the cold groceries and slid a fresh loaf of bread into the bread box. Something about the room seemed off. Nothing really looked out of place, and yet there was definitely a new variable for her senses to unravel. She tried blending her awareness into her surroundings, letting her field of vision blur with a wide aperture. She inhaled deeply. Perfume. Not hers. Chanel? Dior? Something like lingering grapefruit. But something else too. Bitter. Sharp on the top of her palette. Like a hazy beer. Pot? Jack doesn't smoke pot.

She wandered into the den and looked around. A woman's black leather handbag. Chanel. And in the ashtray - a wedding gift they'd never used but kept on the coffee table as a paperweight - a roach blackened by combustion. Jill!

What the fuck is my sister doing in my house? I haven't seen Jill since Thanksgiving. What's she doing here from St. Louis? She heard a giggle upstairs and a tiny squeal. Her heart sank.

Jesus, she thought. I told him to think of someone to invite to bed with us. But my sister? What the fuck?! She slowly crept up the staircase and paused on the second floor landing to listen again.

"Mmmm, that's it. Just like that!"

Son of a bitch! She thought. My skank sister fucks my man the second it becomes a possibility for him to sew some wild oats. How could he do this to me? What on earth would let him think THIS was ok? I certainly can't join them! Her mind was racing with rage; rage, and a tinge of something else.

Something stirred inside her as she listened to her sister squeal with delight as her husband's dick railed her. Not jealousy. Not rage at all. Something nice and soft and warm. She could hear his breathing as he humped her. That adorable Tai Chi thing he learned to improve his stamina. Maybe it had worked after all? She just thought it was his familiarity with her pussy.

She still caught those citrus notes from Jill's perfume. It was light and carefree like a Sauvignon Blanc on a warm spring afternoon. But now it was mixed with something much more carnal. It was sweat. His BO and hers. They'd mixed together into a musky potpourri that struck her nostrils harshly but lingered in an arousing way. Somehow she wanted to taste that scent. She wanted to fuck that scent.

What am I thinking?! Join them? Ugh. They'll be lucky I don't kill them. No jury would convict me. But still.

Mom and Dad have been dead and gone for 7 years. Jill has no one meaningful in her life. She's come up through her 20's marching to the beat of her own drum. Jack isn't a prude, he's just naive. I bet he saw a twins porno or something like that and decided the best threesome would be a sisters threesome. She rolled her eyes thinking about the strange brain her husband has.

The arousal between her legs was palpable. Fine, she thought. Let's do this.

She strode over to the bedroom door and opened it. There he was. Her husband with his dick balls deep in her 25 year old sister's cunt. They both gasped and turned to face the door.

"Don't fucking stop!" Jill said, with a hungry look in her eyes. Jack thrust into her again and again, a stupid, guilty expression plastered on his face.

"What do we have here, Jack?" She said incredulously. Hello Jillian.

"Don't act all surprised, Susan." Jill said, reaching down to rub her clit as Jack's cock began to slow its thrusts.

"Get your whore cunt off my husband's dick!" The rage momentarily consumed her, spurred on all the more by the fact that the sight of it had caused her to soak her panties.

"Relax, Jack called me to tell me about your little idea to swing. He was nervous about it and wanted some advice."

"So you went to the St. Louis airport to come fuck my husband?"

Jill rolled her eyes. "We can be mad about this later, Susie. For right now, you walked in just as I was about to cum on your husband's cock, and I'd really like to get back to that."

There was a long heavy pause. Susan eyed the two of them, her sister on all fours like a dog with Jack's fat length about halfway into her pussy. She weighed the options, and recognized right away that this was happening no matter what. She'd flirted with this idea, and now it was reality. That's what happens sometimes when you let your fantasies take on a life of their own. She sighed and began to unbutton her blouse, revealing a forest green lace bra she'd picked out earlier in anticipation of having Jack for dessert later tonight.

"That's the spirit, sis!" Jill shouted! She turned to look back at Jack. "Get back to it, stud. Fuck me!"

"Not before I have a taste." Susan said cold and deliberately.

She tossed her blouse on the floor and walked over to the bed. She pulled Jack out of Jill's snatch and wrapped her lips around his cock. The sweet and sour juices of her sister's pussy mixed with Jack's signature precum was delicious. She felt her own juices trickling over the folds of her pussy as she began to bob up and down on Jack with her mouth. She sucked him until his cock was rock hard again and then stood up to look at Jack. Stroking him slowly, she met his gaze.

"This is what you want, baby? My little sister isn't taking advantage of you? You want your first threesome to be a fuck fest with both of the Webster girls?"

Jack smiled nervously and nodded his head eagerly.

"Well, it's definitely kinkier than I expected it to be, but I'm not going to pretend it doesn't turn me on." She stroked him a couple more times before spitting on her sister's cunt and guiding Jack's penis back into her wet hole.

Jill's pussy sucked Jack back inside her and she moaned with delight.

"That's it, Jack! Fuck your sister-in-law. Stretch me out with that big, fat cock of yours. Fuck! My sister has been holding out on me. And we all thought she was a prude. Who knew my sister's pussy was getting stretched like a dirty little whore!"

"Shut up, bitch!" Susan exclaimed as she positioned herself on her back, displaying her wet panties to her sister. Jill's eyes widened as she gazed on her sister's dripping pussy. Jack's thrusts coming faster and faster until he was pushing her face into the wet fabric of Susie's wet panties. Jill grabbed Sue's legs for support and moved the fabric aside with her teeth.

"Fuck her, daddy!" Susan exclaimed. Fuck her while she eats my wet cunt!"

Jack did exactly that, the tempo of his movements reaching a fever pitch. Jill squealed with pleasure as Jack slammed inside her again and again before she planted her lips on her sister's clit and began to lick and suck her little bean. Susan moaned with delight and ran her fingers through her sister's hair, opening her eyes to watch Jill's tight round ass shake as Jack rammed the full length of his throbbing sex into her like an irreversible, ratcheting cog. Each thrust pushed Jill's face up against Susie's pussy. Jill stuck out her tongue and worked it into her warm, drenched folds so that Jack's thrusts caused both girls to be penetrated.

"That's it, Honey! Fuck my sister's pussy!" Susan said, encouragingly. "Jill, we always said if we gave a woman my tits and your ass he'd die from the sight of it. Now we get to see what kind of a man my husband really is!"

"Mmmm, he's a man with a huge fucking dick! That's what he is!" Jillian shouted. "Oh fuck, just like that! Oh fuck my brother-in-law is going to make me cum on his fat cock! Oh fuck! Oh fuck!!"

She screamed loud enough to wake the dead. The intensity of it sent Susan into orbit too and both women began shaking uncontrollably as he fucked Jill harder. As their orgasms subsided, Jill crawled off of Jack and scooted up to sit on Susan's face. Jack scooted up as well and began hitting Susan's glistening clit with the head of his cock.

"That's it. Be a good husband and use my fucking cunt!" Susan growled as she began to tongue fuck her sister's vagina.

"Yes, dear." Jack said confidently. He pushed his cock deep into Susan's pussy and growled as he felt her muscles tightening around his shaft. He could feel her cervix cupping the head of his penis and it made his member throb and swell inside her.

"Don't you dare tell us which one is tighter!" Jill exclaimed, causing Susan to giggle wickedly. Jack could feel Susan's laughter vibrating along the walls of her pussy, and it spurred him to fuck her faster.

"Oh fuck! Mmmm fuck!" Susan muttered between slurps on her sister's clit. "Mmmgfh! Oh go..... oh fu.... fuck!!!!" She screamed. Her orgasm exploded out of nowhere. "Oh fuck, Daddy! I'm coming! I'm coming on your fucking cock!!" Her muscles clenched and her left leg juggled reflexively. Jack thrust deeper and harder as she peaked, and the sight of her perfect tits jiggling just beneath Jillian's tight ass pushed him past the point of no return.

"Oh fuck, Susie!" Jack exclaimed as his cock exploded inside of her. She could feel the pulses of his dick as he painted her insides white with thick ropes of hot, sticky cum.

Jillian sat up off of Susan's face and turned around as Jack pulled out of her. She grabbed his still hard cock in her hand and sucked the cum off his tip.

"Mmm fuck sis! Jill exclaimed. "I always knew Jack was a keeper. But damn!"

Susan grabbed Jill's hair and pulled her off Jack's dick. "He's mine, sis. Get down there and lick his cream pie out of my cunt."

Jill did as she was told. Susie got on her hands and knees and let Jack fuck her mouth while Jillian bent over to lick the thick white cum dribbling out of Susie's pussy.

"Fuck, he tastes delicious, sis!"

"I know," Susie exclaimed between deep suck on her husband's shaft. "And we're not done with him yet."
