The couple had just celebrated their fourth wedding anniversary, and went out to have a few drinks at a new trendy cocktail bar, hidden behind a steel door in an alley, a few blocks from their newly renovated penthouse. Most of their time was spent working in corporate law. Michael had just made partner, while Kim was recently promoted to run the firm's mergers-and-acquisitions division.
"Is that the intern that wanted to fuck you last summer at the bar?"
"In fairness, you wanted to fuck her, as well."
"True, the timing was off with the Mendelson merger, and I barely had a minute for anything."
"Excuse me," calling to the bartender, "we'd like to send a round down to the dirty-blonde in the black dress sitting next to the brunette, thank you."
The brunette was leaving, and...
"Hey guys, funny to run into you here. Thanks for the round, but sadly, my friend Vanessa must leave to deal with boyfriend drama."
"Oh, no worries, you looked like you were in a serious discussion and we didn't want to disturb you."
"Not at all, she needs to get laid, and by a man who isn't her dickhead of a boyfriend."
"Perhaps, a girlfriend might be better suited to get her back in the swing of things?"
"I like the way you think," she said, sitting down next to Kim, and ordering a drink from the handsome man behind the bar.
"What about you? Boyfriend, girlfriend, both?"
"I've enjoyed the touch of a woman before, and have a new boyfriend I met through my new job."
"He is a very lucky man," Michael said.
"As is your very beautiful wife." The young woman tried not to show her fuck-me eyes too strongly, before feeling Kim's hand on her thigh.
The threesome stayed at the bar for the better half of two hours, sipping on cocktails and conversing about highly sexual topics. It was a very easy and natural conversation for them. The women went to use the bathroom, and Michael paid the bill. When they returned, he proposed a tour of their new penthouse as they headed towards the exit and back into the alley.
"I'd really like to see it, but I was supposed to see my boyfriend tonight."
"Tell, him to meet us there."
"I can call him, give me a minute."
The couple waited, as she made the call.
"Will your handsome boyfriend be joining us this evening?"
"He is sick and wants to meet you all another time. I think you guys would get along with him. He's a good dude."
"Is he good, or great?" Kim snickered to Lisa, clutching her arm, walking down the alley.
"Great. He is an unbelievable giving lover."
Once inside the penthouse, Michael made them drinks, and watched his wife seduce their former paralegal from across the room, right before Lisa excused herself to use the bathroom, seductively staring down Michael, as he finished mixing their drinks.
The couple didn't have to say a word, and already knew exactly how this was to unfold when she returned.
"You could fit a football team in the shower, do you think it has enough shower heads?" popped off Lisa, walking back into the room.
"There were seven of us last month, or was it eight?"
"It had to be seven because Tommy, and Marco had Jennifer in the master bedroom."
"I thought they took her on the balcony."
"No, that was after. And Marisa joined them while James watched."
Lisa listened to the couple openly share the details of their sex life, and was eager to hear more, but before she could say anything else, the couple was then on each side of her. Kim leaned in for a short kiss and a taste of her lips, followed by a long, deep kiss from the woman's husband. He grabbed her by the back of the neck with his strong hands, gently biting her lower lip.
The young sexpot was taken off guard, but wanted every bit of it from the experienced couple.
Kim stood to the side, watching, and waiting patiently before slowly approaching the pair, grabbing hold of that twenty-two-year-old ass, gently squeezing apart her firm cheeks. "Do you like the way my husband is touching you now?"
"Yes, yesssss," she purred, in satisfaction from his touch.
"We are going to have a lot of fun with you tonight. Would you like that?"
"Uh-huh, yes." She lunged towards her former boss, kissing the beautiful blonde.
Her panties, by then, were soaked, sandwiched in between the sexy couple, moaning into the older woman's mouth. He rested his throbbing cock on her backside; his wife took control of her by slowly licking her neck while moaning into her ear.
"I can't wait to lick your tight little pussy," she whispered, sliding the straps on her cocktail dress down her tan arms, stopping above her waist, making sure to take in the full view of her perky young breasts, grabbing a handful before slowly teasing her nipples with her exceptionally long tongue.
"Fuck that feels good," was the response, as she reached around her back, pulling him closer, feeling his cock grow longer and thicker, as he pressed into her firm ass.
Michael spun her around, while Kim pulled her dress further down, letting it fall on the hardwood kitchen floor, before he kissed her deeply, holding her head in between his strong hands, yanking her head back, and running his tongue along her neck, suckling on her ear.
Kim had disappeared from the kitchen, and in her absence, Lisa dropped to her knees, without breaking her line of sight; undoing his belt with one hand, and tracing the outline of his hard cock through the front of his pants with the other.
"How big is it? Will you show it to me?"
"I don't know, your boyfriend might not appreciate that."
"We have an understanding. Anything that happens tonight will be discussed in detail later with him. The only thing we like more than fucking each other, is watching each other get fucked."
"Good for you two. I guess I can help you out since you asked nicely, but I must warn you-- the only thing little here, is your tight, little pussy, and after tonight, you'll never be the same."
"Promise?"
Michael stepped away, leaving her hanging in desperation, hungry for him to reveal his massive bulge.
Kim, having returned, reached down, hooked her finger under the young woman's chin, guiding her back up on her feet. "The only promise that will be made tonight, is that little pussy of yours, that is now ours, and will be fucked properly. I am curious, though, how that rock on your finger will look wrapped around my husband's thick cock, sucking on his balls? If you think your fiancΓ© won't mind, then go ahead into the bedroom. He is waiting for you to try his cock on for size."
And just like that, Kim ushered her towards their marital bed, gave her a good smack on the ass, and watched her enter the next step in her sexual evolution.
Michael, shirtless, circled the bed while staring at her as she entered the room, meeting her at the foot of the bed. She submissively got on her knees, her panties dripping wet in anticipation. Kim was watching the scene unfold from behind, oozing sex appeal, having changed into a white corset that pushed her huge tits just right. Her hard nipples were taking form through the lace, which was perfectly complemented with a short, lace garter skirt that stopped just above her tight ass, and white patent-leather ankle-strapped stilettos.
Michael lifted her up onto his shoulders, pinning her back against the wall, and started eating her pussy like a champ. Slowly, he shoulder-pressed her tiny frame up and down on his tongue. He felt her getting close, and placed her down on the bed. With her asshole spread open for the world to see, he continued with several long, slow, commanding licks of her pretty little balloon knot before throwing her up towards the head of the bed, where Kim patiently waited.
