THE BUSINESS TRIP ==================================================
A CHANCE MEETING ==================
Andrew accepted his second gin and tonic from the bartender and threw a ten-dollar bill on the bar. He was grateful for the chance to chill out after a grueling day of travel and meetings. His flight departed from Dallas at 6:20AM earlier that morning, and arrived in Atlanta at 9:10. After hours of meetings with his prospective clients in downtown Atlanta, Andrew escaped back to the hotel for a much-needed early dinner. The steak and grilled vegetables had been only passable, not great. After dinner, he went up to his room to change into casual clothes, threw on some khakis, a striped oxford shirt (tails out) and his suede Merrells. Now, here he was at the bar, enjoying his second cocktail, and he finally began to feel the tension of the day slip from his shoulders. He was getting a warm glow from the liquor, and enjoying a cigarette, a vice he did not normally allow himself.
Looking over the rim of his cocktail glass, he noticed an attractive couple entering the bar. The woman was exotic- looking, with beautiful olive skin tones and almond shaped eyes. Her hair was black and layered from the front of her forehead, sweeping back to just past her shoulders. She was wearing a crop-top denim jacket over what appeared to be a lacy camisole. Her cleavage was evident in the camisole, and a diamond pendant accentuated the vee between her breasts. She was wearing a black mini-skirt with a floral pattern on the front in scarlet embroidery. Her high heels had straps that wrapped around her pretty ankles to about halfway up her calves. Andrew took note of her ass when she turned to kiss her husband. Her buttocks were on the large side, but remarkably shapely. Her ass was a little larger than what he normally preferred, but he could not help whistling softly at the sexy roundness of her cheeks. She turned back toward the bar entrance as her husband made his way toward the men's room across the lobby.
"Now, that's a J-Lo ass, for sure!" remarked the bartender.
"You know, my friend," replied Andrew, "you are exactly right. And that woman could substitute for J-Lo in my book any day!"
The bartender chuckled and nodded in agreement. He turned away to fill another order, and Andrew swiveled in his chair to return his attention to the pretty dark-haired woman. He was surprised to see the beautiful woman heading directly toward him! She stopped at the chair next to his and sat down, tugging slightly on her skirt as she hopped up on the seat.
"Is it okay with you if my husband and I take these two seats?" she smiled at Andrew.
"My pleasure!" he replied, "My name's Andrew. And yours?"
"Mary," she extended her hand to Andrew, "short for Mariana. It's a pleasure to meet you."
"With a beautiful name like Mariana, I don't know why you'd want to shorten it." Andrew shook her hand, "Mind if I call you Mariana?"
"Not at all, if that's what you prefer," she replied amiably. "My husband's name is Mark. He should be here in just a minute."
At that moment, Mark appeared behind Mariana and gave her a quick kiss on the neck. He sat on the other side of his wife, and reached across to shake Andrew's hand. Mark was about 5' 10" tall, slender and well-dressed. His hair was close-cropped and he was wearing jeans, topsiders and a polo shirt.
"Hi, my name's Mark. I guess you've already met my wife, Mary."
"We were just making introductions," replied Andrew, shaking the offered hand. "Are you two here on vacation?"
"Actually, we're from right here in Atlanta." Mark replied, "We like to cut loose every once in a while, grab a room downtown, dress up a little and get away from the kids and the house, know what I mean?"
"I know exactly what you mean," Andrew said, smiling. "You've got to shake loose sometimes just to keep your sanity!"
Mark and Mariana laughed and agreed with Andrew.
"Hey, let us buy you a drink while you tell us what you're doing here." Mariana said. "Maybe we can grab a table and chat for a while? What are you drinking?"
"I was having a gin and tonic," Andrew replied, "but two's my limit unless you want a sloppy drunk on your hands. I think I'll just have a glass of Shiraz, thanks!"
They ordered Andrew's wine and moved to a table. Andrew noticed that Mariana hitched up her skirt a little to reveal the top of her hose. He saw a lacy garter attached to her stocking, and he felt a stirring in his pants. Andrew was even more surprised when he glimpsed Mark's hand on Mary's thigh, pushing her skirt up even further. Embarrassed, Andrew looked away and took a sip of his wine. Out of the corner of his eye, he caught Mark and Mariana smiling at one another.
Andrew found himself wondering what kind of game Mark and Mariana were playing. They were obviously coming onto him in some way, but he didn't quite know how. The thought crossed his mind as to whether they might be into three-way swinging. He considered the possibility as the three of them chatted.
The three of them made small talk for a while, Andrew explained the nature of his trip, and Mark asked some questions about Andrew's computer consulting business. Mariana loosened up with the drinks, and began to punctuate her conversation with light touches on Andrew's arm. She had removed her jacket and placed it over the back of her chair. Her camisole was surprisingly sheer, and Andrew could just make out the dark brown shapes of her nipples under the silky garment. Several times, she leaned over to make a point, resting her hand on Andrew's arm. During it all, Andrew noticed Mark's hand actively caressing Mariana's thigh, even slipping his fingers dangerously close to her crotch. Mark made a couple of suggestive remarks about their sex life during the conversation.
Andrew's mind wandered a little as he listened to Mark and Mariana talk. He wondered if Mark was into seeing his pretty wife get fucked by another guy. "Nah, he doesn't seem like that type," thought Mark, "I wonder if he's bi?" The thought of that sent a rush of adrenalin through Andrew's body. Ever since he and his college roommate had experimented with masturbating and sucking each others' cocks, he had always wanted to try a bi-sex scene with a couple. Andrew amused himself by imagining Mariana and him going down on Mark's cock together. He felt his own rod stiffen in his pants as he visualized the scene.
"Andrew? You still with us?" Mariana interrupted his daydream, "You went kind of blank there for a minute."
"Sorry!" Andrew recovered, "What were you saying?"
"We were wondering if you had any plans for tonight?" Mariana asked Andrew, "Going out on the town?"
"No, I don't have any big plans at all," Andrew replied, "just thought I'd relax with a couple of drinks, and I'm really enjoying talking with you. I guess you two have a lot planned for the night, huh?"
"Well, yes, we do," Mark stole a furtive glance at his wife, "but maybe you'd like to join us for the evening? Like I said earlier, we like to get away every once in a while and party a little. This is one of those times!"
Andrew took a sip of his wine to stall for time. He now knew for sure that Mark and Mariana were coming on to him, especially the way they were flirting with one another, and for that matter, with him! "What exactly did you have in mind?" he asked.
It was Mariana that spoke up after a brief pause. "Well, Andrew," she began nervously, "can we be very frank with you?"
"Please do!"
"Okay," she continued, "we hope you aren't offended, but we kind of picked you out of the crowd earlier. You see, we like to play when we can get away from the house, and well..." she hesitated for a moment. "Have you ever had a swinging experience?"
Andrew's suspicions were confirmed. This couple was definitely looking for a threesome! Andrew took another sip of his wine and formulated his response.
"Well, I've had a couple of situations in my life, yes. I might be interested. Are you two propositioning me?"
Mark and Mariana laughed together. "I guess you could say that," Mark said, grinning, "But, there's kind of a catch. Kind of a big catch. I'll excuse myself to go to the men's room, and Mary can explain." With that, Mark stood and left the table.
When he had left, Andrew looked at Mariana. "What's the catch?" he asked.
"Well, you may not like it, but here goes," she looked down at her drink, "you see, Mark is bisexual, and I like to watch!" She looked up at Andrew and gave him a sheepish grin.
Andrew felt his heart jump high into his throat. So that was the deal! Andrew felt a bead of sweat trickle down his forehead. For the past several years, he had harbored a secret fantasy about having a bi experience. He had even gone so far as to rent porno flicks featuring two guys and one girl, and had found them extremely erotic. He especially got horny when the guys in the movies sucked each other off while the girl watched and joined in. Now, he was in a position to make his wildest fantasy come true!
"Andrew, you okay?" Mariana asked. "Do you want us to leave you alone?"
"No!" Andrew quickly replied. "I'm just thinking, that's all. Maybe you better tell me exactly what you two would like to do. I'm still interested."
Mark came back to the table and said "Well, you're still here, so I guess we haven't scared you off yet."
They ordered another round of drinks. Mark and Mariana explained to Andrew that they enjoyed "performing" in front of another guy, then letting Mary watch as the guys performed for her. They had one rule – Mark was the only one who could fuck Mariana, but sucking and touching was okay.
Andrew sat back in his chair, momentarily dumbfounded. What were the odds of this happening? He thought about their proposition, imagining the couple in front of him in the nude, playing with each other for his benefit. He thought about what it would be like to stroke Mark's dick as Mariana licked it. Finally, he spoke up.
"You guys drive a hard bargain!", he said, smiling, "What the hell, sounds like fun!"
They agreed to meet in Mark and Mariana's room in one hour.
Andrew left the bar with his heart skipping wildly. He went up to his room to shower. In the shower, he decided to touch up his shaved cock and balls. His mind was racing a thousand miles an hour. "Can I actually do this?" he asked himself. "Is this for real? What if I freak out? I'm actually going to put another guy's dick in my mouth and play with his balls?" As he pondered these crazy questions, he got his answer – looking down, he saw his cock standing rigidly at attention.
ROOM SERVICE ==============
Andrew was as nervous as a cat as he knocked on the door of room 517. Mark answered the door wearing a white terry cloth robe and holding a martini glass. When he saw Andrew, he waved him in and offered him a drink.
"We weren't sure whether you'd actually come!" said Mark, handing Andrew a fresh drink, "Glad you could make it!"
Andrew's eyes grew accustomed to the dimly lit room. There was one lamp turned on, and sitting in the chair beside it was a gorgeous Mariana, wearing a silk Oriental robe over what appeared to be a white lace teddy. She wore the same sexy high heels he had seen her in earlier in the bar. She waved and smiled at Andrew as she sipped a glass of wine.
"Come sit down and enjoy your drink," Mark said as he led Andrew to a chair. "We know you're probably nervous, so just relax for a minute."
Andrew gratefully accepted Mark's offer and sat heavily in the chair next to Mariana. Mark sat on the arm of Mary's chair, and she playfully let her hand fall between his legs. She began to stroke Mark's thighs. Andrew took a long drink from his glass, feeling the warmth of the liquor in his throat.
"Andrew, you know what our story is," Mark said, "and we know you agreed to it, but have you ever had any experiences with another man? I mean, there have times that Mary and I have hooked up with a guy whose only interest was to try to get into her pants, and they really weren't interested in the bisexual scene, you know?"
Andrew considered his response. "Well, to be honest with you, I've had only two experiences in my life. When I was a kid, my buddy and I had a slumber party, and we spent hours talking about girls and sex. We got ourselves pretty horny, and we ended up taking turns sucking each off, just to see what a blow job felt like. I was really surprised by how turned on I got when I went down on him." Andrew paused to take another drink. Mark and Mariana were smiling and nodding.
Andrew continued, "Another time was when I was a freshman in college. My roommate was a good-looking guy, but real shy. He was obviously frustrated about his lack of success in finding girls at college. We had a lot in common, and we were able to talk pretty freely about our feelings and stuff. Anyway, we had a bunch of beers one night in the dorm room, and he confessed to me that he had this fantasy about sucking a dick while fucking a girl. I told him about my buddy and I when I was a teenager. One thing led to another, and we ended up laying on our backs and jacking each other off. Then we got into a 69, and he sucked me while I licked his cock and played with his balls. We only did it that one time, but I've always wanted to again. Does that answer your question?"
Mark laughed, and Mariana said "That makes me horny just to hear about it!"
She stood up from her chair and removed her robe. Andrew was thrilled to see her standing before him in a sheer, lacy teddy. Her breasts were full, with creamy brown mounds of cleavage bulging above the white lace material. Her husband stood behind her and began rubbing his hands up and down Mariana's arms. As he stood up, Mark's robe fell open, but he was hidden from Andrew's view by Mariana.
"Andrew, why don't you let us make you feel at home? Whenever you feel like it, feel free to take off your clothes and enjoy the show," Mark said.
Andrew raised his glass and toasted the couple standing before him. Mariana placed her hands low behind her back, and Andrew could tell that she was stroking Mark's cock behind her back. Mark ran his fingers up to his wife's shoulders and gently pulled the thin straps of her negligee down her shoulders. Kissing her neck, he slowly peeled the teddy down her body, revealing her full breasts and dark chocolate-colored areoles to Andrew. Her large nipples were erect. Mariana stared at Andrew as her husband stripped her nightie from her. Andrew squirmed uncomfortable in his chair, his cock rising against the fabric of his pants. Mark pulled the teddy all the way down to Mariana's high heeled shoes, and she gracefully stepped out of the garment.
She was wearing a white thong panty with string ties on the sides. Through the lacy triangle that barely hid her pussy, Andrew could tell that she was smoothly shaven. He could discern just a shadow hint of her pussy lips beneath the fabric. Mark ran his hands up to Mariana's breasts and gripped her stiff nipples between his fingers. She gasped slightly as Mark pulled her nipples. She turned to face her husband, and Andrew was rewarded with a view of her ample round ass. The skin on her ass cheeks was smooth and brown. Her ass was not wide, but very full. She reached up to Mark's shoulders and pulled off his robe. Slowly, she ran her hands down his chest and began to kneel in front of him. As she reached his stiffened cock, she turned him sideways. For the first time, Andrew saw Mark's erect cock. It was about seven inches long, and standing up proudly at a forty- five degree angle to Mark's thin belly. His pubic area was shaved smooth. Andrew's felt his own cock surge with desire. He stood and began removing his clothes.
Mariana watched Andrew undress as she slowly stroked her husband's penis. Mark was also watching Andrew. Andrew was not wearing underwear, so his cock was freed as soon as he peeled off his pants. It stood stiffly in front of him as turned to face Mark and Mariana.
"His cock is beautiful, isn't it?" Mary asked her husband, "So stiff and smooth, just like yours!"
Mark agreed, staring at Andrew's hard-on. Mariana turned her attention back to her husband's erection and began to play with his balls, tickling them with her long fingernails. She stroked the top of Mark's penis with her fingers and rubbed his shaft up and down the side of her face.
"Andrew, do you like Mark's cock?" Mariana asked with a wicked grin, "Isn't it nice? It feels so wonderful just to stroke his skin and play with his balls. Would you like to see how nice it feels?" She grasped the base of Mark's cock and held it out for Andrew to see.
Andrew stepped closer to the couple and stood side-by-side with Mark. Looking down at Mark's awesome hard-on, he reached down to grasp it with his left hand. He heard Mark inhale deeply as Andrew's fingers closed around the throbbing shaft. Andrew closed his eyes briefly to enjoy the silky feeling of Mark's cock in his hand. He felt Mark's arm brush his stomach, and then was thrilled by the touch of Mark's fingers on his own dick. He looked down to see Mark's fingers gently stroking the hood of his dick.
"That's nice, boys. Two beautiful stiff cocks! Let me watch you play with each other for a little bit!" Mariana said as she cupped Mark's balls in one hand and Andrew's in the other. She was staring enraptured as the two men stroked each others' cocks. Their position was a little awkward, so Mark and Andrew turned to face one another. This placed their hard dicks in front of Mariana's face, and they reached across her to resume fondling one another. Andrew held Mark's stiff shaft in the palm of his and wrapped his fingers around it. He slowly stroked Mark's cock, feeling the smooth skin caress his palm. He fondled the undersides of Mark's heavy balls with his fingertips. Mariana knelt on the floor sideways to the two men and caressed their asses with her hands while she watched the show.
Mariana stood up and whispered something in her husband's ear. Mark nodded in agreement while his wife sat down in the chair. She spread her legs and placed them on either side of the chair arms, exposing her glistening wet pussy to the men.
"Mary wants to watch me suck you while she plays with herself," Mark told Andrew, "and she wants you to watch her. You okay with that?"
Andrew nodded dumbly, his heart beating fast. He reluctantly released Mark's throbbing manhood to allow Mark to go to his knees. He watched Mark's hands grab the base of his pulsing cock as he began licking the tip of Andrew's penis. Andrew closed his eyes momentarily in ecstasy as Mark took half of his dick into his mouth. He felt Mark's tongue circling around the head of his penis, and he knew that Mark was tasting salty pre-cum that had been building at the tip of his cock.
"Mmmm, honey, you're making me so horny!" Mariana exclaimed as she watched her husband engulf Andrew's shaft. "Suck that pretty dick for me, baby!"
Andrew remembered that Mariana wanted him to concentrate on her, so he turned his gaze toward the chair. She was pinching one of her dark brown nipples with her fingers. Her other hand was busy rubbing her wet pussy lips around in circles. When she noticed that Andrew was now watching, she spread herself open with the fore and middle fingers and smiled at Andrew. Her labia were dark brown on the outside, almost black, and her inner lips were a beautiful slippery wet pink. She held her lips open with one hand and began gently tapping her clitoris with one finger of her other hand. Andrew was mesmerized watching her lightly spank her clit. She began to moan softly. Andrew could see her pussy clinching and pulsating slightly as she masturbated herself. When she was satisfied that Andrew was enjoying the show, she turned her gaze back to Mark to watch him feast on Andrew's cock.
Mark pulled his attention away from Mary's sexy pussy to watch Mark suck his cock. He was fascinated by the strange sight of seeing a man's head at his crotch. He watched as Mark slowly face-fucked his stiff cock. Mark massaged Andrew's balls with his fingers as he sucked and tugged Andrew's dick with his mouth. Andrew was starting to feel the onset of orgasm when Mariana spoke up.
"Mark, honey," she said hoarsely, "why don't you see if Andrew would like to sample yours?"
Mark pulled his lips off Andrew's cock. He stood up, still holding Andrew's pulsing dick in his hand.
"You want to try sucking me?" he asked Andrew.
Andrew answered by dropping to his knees in front of Mark. He was now face to face with Mark's manhood. He could see traces of pre-cum on the end of Mark's cock. Almost without thinking, Andrew grasped Mark's thick cock and licked the juice off the tip of his penis. He placed his lips around another man's cock for the first time since college. He felt as if he was in a trance as he began to enjoy the feel of Mark's dick filling up his mouth. He tasted a trace of Mark's pre-cum. He closed his eyes and swallowed. He heard Mark moan.
"Isn't Mark's dick tasty?" Mariana asked Andrew, "Don't you love it?"
"Mmm – hmm!" Andrew replied, his mouth full of Mark's hardness. He glanced over at Mariana and saw her pushing her fingers well inside her sopping pussy.
After a few moments of bliss watching Andrew suck Mark's stiff shaft, Mariana suggested that they move to the bed. She rose from her chair and grasped Andrew's hard-on with one hand to lead him to the bed. She arranged him on his back and turned to her husband, beckoning him to come over. Mark knelt on the bed, straddling Andrew's waist. His cock rubbed against Andrew's. He reached down and took both their dicks into his hand and began slowly stroking them together. Mariana walked out of the room to the restroom area for a moment. When she returned, Andrew was shocked to see her wearing a strap-on device around her waist. Protruding from the strap was a 6" life-like rubber dildo. She was carrying a small bottle of lubricant and a bath towel.
Andrew watched in disbelief as Mariana knelt on the bed behind her husband and uncapped the lubricant. She lathered the slippery substance sensuously all over "her" cock.
"Honey, I brought you a little treat!" she said to her husband. Mark turned around to see what Mariana was up to, and smiled when he saw the strap-on dildo.
"Why don't you move back a little so you can suck on Andrew's pretty cock while I fuck you with mine?"
Mark complied, scooting himself away from Andrew's waist. He stuck his ass up in the air and bent down to take Andrew's glistening dick into his mouth. Mariana moved up close behind her husband's ass and poured some of the lube down the crack between his butt cheeks. She started rubbing "her" stiff cock up and down between Mark's cheeks. Mark moaned as he felt the dildo rub across his anus. Andrew was watching Mark's lips and tongue massage his dick when he felt and heard Mark moan louder. Mariana pushed the head of the dildo against Mark's asshole, and it began to slip inside.
"Ohhh, baby, that feels good in my ass!" Mark exclaimed.
Mariana pushed the dildo into her husband's ass further, eliciting another moan.
"Andrew, do you want to watch me fuck Mark?" she asked.
Andrew readily agreed, even though it meant removing his throbbing cock from Mark's hungry mouth. He got to his knees on the bed and moved around to position himself beside the beautiful woman. He was mesmerized to see her fucking Mark's asshole with the dildo. Mariana reached down to play with Andrew's dick while she slowly fucked her husband. Mark supported himself on his hands and moaned louder as his wife thrust the rubber cock in and out of his ass. While he watched the action, Andrew reached up to massage Mariana's nipples. She threw her head back and closed her eyes as Andrew played with her tits. Andrew continued to watch the rubber dildo stretch Mark's anus tight as it plunged in and out. He felt as if he might cum any minute!
Andrew scooted around until he was sideways to the couple. With his left hand, he reached under Mariana's plush ass and began stroking her sopping wet pussy lips.
"Oh yes!" Mariana exclaimed, "He's playing with my pussy, honey! It feels so good..." With his right hand, he reached under Mark's belly to take hold of Mark's cock. He stroked Mark's cock while fingering Mariana. He felt as if he had been transported to a fantasy land of hot, steamy sexual beings.
As Mariana continued to fuck her husband's ass, Andrew moved underneath him and turned his body so that his face was directly under Mark's hanging penis. He reached up to Mark's dripping cock with his tongue and licked the pre-cum from the tip. He felt Mark pulling his hips around to a 69 position, and he eagerly allowed Mark to place him there.
"That's it boys," Mariana said breathlessly, "suck each others' hard dicks for me! Let me watch you suck cock while I fuck my hubby!"
Mark began to groan as his wife plunged her strap-on dildo harder into his asshole. Andrew sensed that Mark was approaching orgasm. He sucked harder on Mark's dick and reached up to grasp the base of Mark's cock with his fingers. As he felt Mark's cock throb and grow even harder, Andrew pulled his mouth off Mark's cock and furiously pumped with his hand. Mark cried out in ecstasy, and Andrew felt hot jets of cum splash across his face and chest and Mark exploded.
"Yes, baby!" Mariana cried, "Cum big for me! Let me see you cum!"
Mariana pulled the rubber cock out of Mark's ass as he collapsed sideways on the bed, breathing heavily. Mariana saw her husband's white cum on Andrew's body. A stream of Mark's cum had landed across Andrew's lips and there were two pools of it on his chest. She greedily bent down to lick her husband's juices from Andrew's lips. They kissed, sharing the taste of Mark's cum between them. She then wiped the remainder of her husband's thick cum from Andrew's chest with the towel.
Mariana moved down to Andrew's waist and knelt beside him. She palmed his throbbing balls in one hand and grasped his pulsing shaft with the other.
"Mark, honey, poor Andrew is in a state here. Why don't you come help me with this big cock?"
Mark rolled toward Andrew's belly. While his wife fondled Andrew's balls, Mark plunged his mouth almost all the way down Andrew's pulsating shaft and began to suck wildly.
"Yes, sweetheart, that's the way! I love watching you suck cock! Suck his cum right out, baby. Show me how eat it!"
Andrew tightened up and thrust his waist toward Mark's hungry mouth and his own orgasm built to a crescendo. Mariana squeezed his balls as he felt his cum rising from deep inside his groin. Mark pulled away from Andrew's dick at the last second, and opened his mouth to catch Andrew's orgasm. Mariana pumped Andrew's cock in at a furious pace and the first stream of hot white liquid shot against Mark's lips.
"That's good, Andrew! Cum for me! Eat his cum, honey!" Mariana coaxed.
Andrew's orgasm slowly subsided as several more shots of cum landed on Mark's face. When his dick began to soften, Andrew collapsed back on the bed, spent. Mariana unstrapped the rubber dildo from her waist and quickly straddled her husband's face, still wet with Andrew's cum juices. Andrew watched as she rubbed her slippery wet pussy back and forth across her husband's face and lips. She closed her eyes as Mark licked and sucked her sopping pussy, bathing it with Andrew's semen. Andrew propped himself up on the bed and sucked her pretty brown nipples as she slowly worked up to her own crashing orgasm.
SECONDS ANYONE =================
Mariana lay on the bed recovering from her ecstasy. Mark excused himself to clean up in the shower, and Andrew was sitting cross-legged beside Mariana, enjoying her naked, flushed beauty.
"Andrew, why don't you fix us a drink while Mark's in the restroom, and I'll go freshen up a little? Can you stay longer?" Mariana asked, her eyes still closed.
"Of course!" Andrew replied, "Are you two up for more?"
Mariana replied with a laugh, "Well, I could sure use a nice hard dick inside my pussy, and I do believe somebody might be just a little curious about my little strap-on device, hmmm?"
Andrew smiled back at Mariana and obediently got up to make the drinks.
