Walking into the bar, the music pounded around them, and Nick protectively placed his hands on Alec's growing belly. They were preparing for the birth – and the subsequent lack of excitement for the time after. That meant, one last hurrah at the club. Nick and Greg, partners, and soon to be parents, Alec, the woman that was carrying said child, and Kylie, friend to them all.

"Nick," Alec chastised, "the baby's fine. I'm only a few months pregnant. We're still in safe territory."

"Besides," Kylie interjected over the music, "once she pops that kid of yours out, you'll never get to come out with us anymore."

Greg held out three shots that he had snuck away to the back for. "I'll toast to that. We've got to get in a few licks before Nicky and I become daddies and can never have fun again."

Nick took one of the shots and raised it up. "I'll toast to that, but under duress. We'll just be having a different kind of fun."

Greg and Kylie laughed and downed their own shots. Leaving her glass on the counter, Kylie took Alec's arm. "Come on, momma. Maybe that belly of yours can get us a table." She steered them to a less crowded section of bar. Sure enough, a small group of young men vacated the table.

"See," Alec said as she sat down, "pregnancy does have its perks."

Kylie laughed. "And we have to virile men here to get us drinks."

"Yeah, right," Greg said. "I had to climb over people to get the first three drinks. I think Kylie has to be the drink bitch because she has the best tits."

"Hey!" Alec slammed her hand down on the table. "What about mine?"

Nick reached out and grabbed Alec's right breast. "They have gotten bigger since we knocked you up."

She swatted his hand away. "I thought you were all about the cock."

Nick stared at her for a second. "I'm sorry, could you remind me again of how you got pregnant?"

"Point," she said, wagging a finger at him. "Still..."

"I don't even want to hear it," Nick said, holding his hands up. "We," he said, motioning to himself and Greg, "had sex with you and now you're pregnant. I think it's safe to say that we find you attractive."

"Yeah," Greg agreed. "And hey, wait. I call no fair!"

Everyone stared at him.

"What?" Greg said, shrugging his shoulders. "Nick got to touch Alec's boob, and I'm over here getting no play at all."

Kylie reached over and grabbed Greg's hand and placed it on her own breast. "Happy now?"

Greg gave it a little squeeze. "I do feel better. And we need drinks!"

Kylie reluctantly stood up. "I guess that would be my cue."

Greg reached over and smacked her ass. "It's all you."

It took a minute for Kylie to respond, but without looking, she reached down and grabbed Greg by the cock. "What was that, Sanders?"

"Uh..."

"Thought so."

Nick looked over at Greg momentarily, and raised an eyebrow as if to say is this how it's going to be. Greg just grinned back.



A few drinks later, they had moved on to a more personal subject.

"So," Nick said, putting his shot glass down on the table, adding to their ever-growing collection. "Have we all had sex with Greg?"

Alec pointed to her stomach and gave Nick a 'duh' look. Kylie finished off her shot before speaking. "A couple of times," she said.

"What?" Nick and Greg responded simultaneously.

Kylie shrugged. "You really don't remember a lot when you're drunk, do you, Greg?"

Greg pounded back another shot. "I think we're all well aware of that."

"Wait," Nick interrupted. "You had no idea that the two of you slept together?"

Greg shrugged. "I'm guessing we would go out drinking and if we were horny after, then...."

"It was safer to fuck each other than a stranger," Kylie finished. "And I always knew with Greg there would be a happy ending," she added with a wink. She turned and spread her legs as she faced Nick. Her impossibly short shirt hiked up enough to give Nick a view of her purple lace thong. "It's so hard to find a man that will please you on such short notice." She let her hand linger on her inner thigh.

Greg kicked Nick from under the table and wiggled his fingers and pointed to Kylie. Nick looked from Greg to Kylie then back to Greg. Kylie never took her eyes off Nick.

Greg made the motion again and pointed back to Kylie. Nick had just enough liquor in his system to reach over and brush his fingers along the side of lace.

Alec sipped on her seltzer. "Come on, Nicky. You can do better than that."

Greg gave her a slight elbow. "You're not even drunk!"

"Yeah," she replied. "But I'm bored, and you know how I think that public sex is exciting."

"Of all the times I offered," Greg huffed, "you never once let me have public sex with you. Or, for that matter, sex at all. Not until Nicky asked if you would carry our baby."

"Like I said," Alec said, tracing her straw through her drink, "you were just never really my type. Although, in retrospect, I do have to say that you were a good lay."

Nick used the back and forth between Greg and Alec to slip his finger under the lace thong, the fear of getting caught making it all that more exciting. Kylie was already slick as Nick inserted his middle and index fingers into her and left his thumb out to massage her clit.

Kylie bit her lip and moved forward in her chair as she gave Nick the best 'fuck me' eyes that she could muster.

Greg stood up and walked behind Alec. He leaned down and started to nibble on her neck as he let his hand slink down under her bra. "Your nipples are starting to get huge."

"If I wasn't so turned on, I'd yell at you."

Kylie let out a soft moan from across the table. She had closed her eyes and her head rolled back. Nick slipped his other hand under her skirt in order to masturbate her more smoothly.

"That's pretty fucking hot," Greg whispered to Alec.

"You're pretty fucking drunk, you know that, right?"

Greg nodded. "Still hot." His hand was still inside her shirt, rolling the nipple back and forth. The fact that the table was in the corner managed to obscure most of the view, but if anyone was looking directly at them, they would know exactly what was happening.

"If you're going to do that," she said, pulling on his other hand and putting it in her shirt, "do it right."

"Yes, ma'am," he said taking the other nipple between nimble fingers and rolling it.

Nick's face was screwed up in careful concentration as he worked to move both hands in the proper motions. Kylie's mouth stayed open as she gasped for air under his ministrations. Her eyes opened wide just before they rolled back in her head and her body shook. The loud music overrode her cries of passion.

She slumped again the chair, breathing hard as Nick grinned and wiped his hands on his own napkin.

"Look at you, Mr. Double Threat," Greg said playfully. He had removed his hands from Alec's blouse and went on as if nothing had happened.

Kylie, still leaning back with her eyes closed responded, "If I remember correctly, you weren't so bad yourself, Greg. What's the verdict Alec?"

Alec grinned as she readjusted her shirt. "I can say that they are both men of many talents."

Greg leaned over and playfully licked Alec's neck. "You're totally just waiting for us to invite you back into our bed, aren't you?"

Alec laughed. "I hate to say it, but yeah. I don't want to be in some bizarre threesome relationship with you two, but anytime you want to take me for a roll in the hay, don't hesitate to ask."

Nick looked over at Kylie. "What about you? Could we take you home too?"

Kylie leaned in, a combination of alcohol and endorphins causing her to land more in Nick's lap than she had intended. "I'll even let you..." she paused and then went right up to his ear. "I'll even let you both fuck me at the same time."

Nick's eyes went wide. "Alright. We need another round of drinks and then we're heading home!" Nick hopped out of his seat, hampered by his erection, and went to the bar.

Alec sipped on her drink. "I can only imagine what you just said to him."

"Double fuck," she said simply.

"You just made his year," Greg said before polishing off his drink. Kylie just blinked at him, not sure of what to say.

"He tried to get me to do it," Alec explained. "But I don't do anal."

"Which is a tragedy," Greg said, slamming his fists on the table for emphasis.

"I have to agree," Kylie added.

"I'll remind you," Alec said, toying with her straw, "that you've only ever seen Greg's cock. Not Nick's."

"And I've handled it fine. In every one of my orifices, thank you."

Nick came back to the table and put the shots down. "I walked into a strange part of that conversation."

The rest of the table laughed at Nick's confusion, and toasted to their new decision.



Half an hour later, Nick was struggling to keep both Greg and Kylie from wandering off as they tried to make their way to the car. Alec walked ahead, keys already in hand, her pregnancy making her the default designated driver.

Nick managed to pour Greg and Kylie into the backseat, but not without protest.

"Sit back with me," Greg slurred as he leaned up against the back of Nick's seat.

"Can't. You and Kylie are too drunk to safely be in the front seat."

"It's 'kay," Kylie purred against Greg's ear. "You can play with me in the back seat."

Greg leaned forward enough to kiss Nick's temple before falling in the backseat with Kylie. Gentle kissing sounds made their way to the front seat. Nick moved to adjust the mirror in his visor so that he could watch.

"Behave," was all that Alec managed to say as she carefully backed out and made her way out of the parking lot.



Nick reached back into the car to disentangle Greg from Kylie's embrace. "Okay you two, get up," he said as he tugged the back of Greg's shirt.

Greg looked up at him, lips puffy and eyes glazed. "Yes, sir," he said happily as he let himself fall into Nick's arms.

"Umpff." Nick nearly collapsed under Greg's dead weight. "You're not necessarily heavy, but you're a lot of dead weight," he said as he tried to pull Greg into an upright position.

"You love me," Greg slurred, throwing his arm around Nick's neck.

"Next," Nick said as he held his hand out for Kylie, who took it and pulled herself out of the backseat.

Carefully, with Greg to his left and Kylie on his right, he maneuvered his party to the door where Alec was already waiting with Nick's keys. "Inside," she commanded. "I have got to pee something fierce."

Alec ran into the bathroom as Nick brought his two wards into the bedroom. "We're going to have some fun."

"I like fun," Greg said, pawing at Nick and Kylie simultaneously. "But we need nakedness. That helps with the fun." He fell straight onto his back, luckily on the bed and not the floor.

"Seconded." Kylie tossed her shirt clear across the room, nearly hitting Alec in the face with it as she entered the room.

"Are you all starting without me?" Alec asked as she threw off her own shirt and dropped her pants. "I'm glad that bed is big enough for all of us."

Nick grinned as he toed off his shoes. "It should be." He stopped and undid Greg's shoes as well. "You ready for this, G?" he asked as he pulled Greg's socks off.

"I'm ready for anything, Boss," Greg replied as he started to unbutton his jeans. After a moment, he let his hands lay limply at his sides, preferring that Nick undress him as he watched Alec and Kylie kiss in their underwear next to him.

"Up," Nick said firmly as he motioned for Greg to lift his hips so that he could remove the offending pants. Once he had removed them, he unbuttoned the top of Greg's polo and eased it up his partner's body. With the girls distracted he took a moment to kiss his way around Greg's pert nipple, finally biting the tender peak.

Greg sucked in a sharp breath and the girls looked at him. He reached between them to Kylie's nipple, which Alec had exposed during their make out session. "He bit me," he explained, rubbing her flesh.

"Poor baby," Kylie cooed and she moved away from Alec to kiss Greg. "I'll make it better for you." She crawled around Nick and onto Greg, straddling him as she kissed him. "I'll make you feel really good."

Nick took the moment to retreat off the bed and get the supplies that they would need. Condoms, specifically, and something to entertain Alec. He reached into their upper drawer, which Greg had lovingly dubbed their "goodie drawer" and pulled out a half used box of condoms and vibrator that he had actually bought Greg as a quasi-joke. Quasi in that it quickly became one of Greg's favorite toys.

Nick ripped a condom packet open and rolled it over the toy before moving to run his tongue along the smooth curve of Alec's belly. "Pregnancy suits you, you know?"

"You're such a sweet talker," she said as she adjust herself for Kylie, who had moved away from Greg and was now settling between Alec's legs. Kylie kissed Alec's thighs before parting her legs and running her tongue over Alec's already engorged clit.

"I thought this was all about fucking Kylie," Alec said between ragged breaths.

Nick placed the vibrator in Kylie's hand for when she was ready and turned his attention to Greg, licking his way from Greg's neck to his mouth and moving in for a lingering kiss. He pulled away to grab a second condom and tear it open. He rolled it over Greg's hardened cock.

Greg kissed him once and grabbed the box before Nick could get to it. "My turn to do you." With careful, steady hands he rolled the condom down his lover's length. He leaned in and bit Nick's bottom lip. "Now or never, baby."

Nick grinned. "I'm good with now."

Greg tapped Kylie's bare rear. "Are you ready?"

Kylie kept her head down as she continued to eat Alec out. She raised her finger in indication that she still needed another moment. It was barely that before Alec's fingers dug into the sheets and she cried out in orgasm.

Wiping her mouth, Kylie lifted her head and gave Greg a wink. "Just one more second." She inserted the toy and shut Alec's legs. "Enjoy the show," she said to the other woman before straddling Greg and sinking down onto his length. She let out a low, feral moan.

"How much prep do you need," Nick asked as he cupped Kylie's ass.

"I like it a little rough," she responded as she bounced a bit on Greg's cock. "I want you both to fuck me hard." She reached back and claimed Nick's mouth as Greg rubbed her clit. She shuddered and gasped, losing contact with Nick.

Nick slicked his condom covered dick with lubed and then rubbed the excess over Kylie's asshole. He got on his knees and spread her cheeks as wide as he could, admiring the way Greg's cock looked already deep in her pussy.

"Ready?" Nick asked.

"Fuck me, cowboy," she growled, leaning forward slightly to enable him better access.

Nick pushed his way in, relishing the way Greg's cock rubbed against his own even from inside of her. Kylie yelped slightly as they both started to move inside of her, rocking her back and forth with enough intensity to move the bed.

Nick planted his hands on either side of Greg's head to keep his balance and stay inside Kylie as both she and Greg moved as well. Nick could feel Greg's hands snaking past Kylie's hips to his own, trying to coax him into a more fluid rhythm.

The gentle hum of Alec's vibrator broke through the sounds of panting and sweaty flesh meeting sweaty flesh and the sounds of the bed creaking under the weight of four people. Nick's hand reached and moved a damp piece of hair from Greg's eyes and to rub the side of his check before Nick gasped when their balls slammed together.

Kylie bit her lip as her eyes rolled back and she screamed out her orgasm. She could do nothing more but lay limp between then and let them take their pleasure in her. Nick and Greg followed soon thereafter.

They lay where they fell, Alec to the side, Nick next to her, Greg next to him, and Kylie finally rolling off Greg and to the edge of the bed. Each of them was worn and sweaty, the sheets damp, and the air conditioning and ceiling fan doing nothing against the muggy scent of sex that dominated the room.
