Erotica Sex Story: Chapter 15 - Tom and Mandy dreamed about what it would be like to go to a swinger party. When they received an invitation, they were ecstatic.

I was too busy imagining what a night with Autumn, April, and Mandy would look like to realize everyone had stopped walking. I just managed to pull up short of slamming right into Rob’s back.
“Shit!” I cursed, nearly spilling my drink all over myself. I looked up to see what was going on, and there was a group of women of various ages and stages of undress walking past us.
“This year might be even crazier than last year,” Rob announced, a dangerous grin on his face as he watched the group of women go by, some of whom turned and gave our group a little wave or blew us all kisses.
“You’re damned right!” Jeremy agreed, merrily.
I only gave them a cursory glance, too worried about trying to keep my drink in its glass.
“You’re still thinking about it, aren’t you?” Bruce chuckled, giving me a knowing smirk.
“You aren’t?” I questioned right back.
“Oh no,” Bruce chuckled, shaking his head. “I gave up on that dream years ago.” Years, how old were they?!
“The chase is half the fun, right?” I replied, giving a slight nod of my head, grinning.
“True that!” Bruce threw an arm across my shoulders.
“Oh, look, there’s the girls,” I heard Jeremy say as he and Rob led us across the room.
“Hey, Tom,” Rob turned, looking over his shoulder at me. “I want to introduce you to—”
“Daddy!” Beck cried out excitedly when she saw the four of us approaching.
Rob’s face scrunched up in confusion at Beck’s announcement, looking to Jeremy for answers, who just shrugged. Whatever questions he had were answered as Beck ran up to our little pack and slammed into me, grabbing my face in her hands and planting a wet, hot kiss right on my lips.
“Wait a damned minute!” Rob stood back, eyes wide. You see the wheels turning in his head as he attempted to process what was going on.
“Don’t even bother,” Bruce warned, glancing over at me and Beck as she kissed me furiously. “No one knows how it happened exactly, so don’t even ask.”
“But I...” Rob started to say, but his words cut off with a click as his mouth snapped shut.
“Alright, for goodness’ sake, Beck,” Mandy laughed, yanking the older woman away from me. “Let go of my boyfriend already.”
“Ah, so this...” Rob grinned, his previous confusion either lost or forgotten; it didn’t matter which, he took in the sight of Mandy with an appreciative gaze. “This must be the famous Mandy I’ve heard so much about.”
“Seriously, Rob,” Beck groaned, hands on hips. I got the distinct impression that this was a usual behavior from Rob. Not to mention that Beck was completely and utterly over the false bravado. “No one believes you when you try to be all chivalrous.”
“Ha!” Jeremy barked a laugh. “She’s got you there, you big ass!”
Rob just grinned, letting the insults roll right off him like water off a duck’s back.
“As I’m sure you’ve surmised, my lady,” Rob bowed dramatically, and everyone, but Mandy and me, groaned. “I’m Robert, but you may call me Rob...” he smirked, and I had the sudden sense of feeling dirty, slimy, and I shuddered. “or any other name you want.”
“Yes, yes, you’ve met. Wonderful,” Beck cut in, taking Mandy and my hand and dragging us away from the group.
I heard laughter in our wake and glanced over my shoulder to see Bruce and Jeremy laughing at Rob, who was still watching us as we pulled away. I don’t know what was going on between Beck and Rob, but there was assuredly some history there.
Mandy and I followed along behind Beck, who was walking like a woman on a mission.
“Where are we going?” Mandy asked, and Beck just turned her head and winked.
I was about to ask the same question when our destination became obvious. On the far wall, there was a massive couch and a pair of women who looked to be about Beck’s age, lounging on the cushions, looking in our direction with sly smiles on their faces as we approached. The two couldn’t have been dressed differently.
The one on the right was wearing a skintight, shiny, black suit that made her look like Catwoman, just without the ears. There was a long zipper that ran up the front of her suit, which was unzipped nearly halfway down to her stomach, more than enough for anyone to get a hell of a glimpse at her ample rack. She had dark, flowing black hair and dark eyes, and a brilliant white smile that looked dangerous as it was beautiful.
The other was wearing a tiny red number that was completely see-through and a matching lacy red bra and panties set. I wasn’t a huge fan of lingerie, but I could see the appeal most would have looking at her. Thigh-high stockings and stilettos rounded out the outfit. Unlike Catwoman, the lady in red was a platinum blonde with all of her hair pulled back into a thick braid that hung in front of her shoulder, resting between her breasts.
Beck led us right to the couch, and all three of us sat down next to the two women. The couch was so massive that there was still room for another three or four people to sit down comfortably. Half a dozen or so if people wanted to get cozy.
“Glad you finally decided to join us, Beck,” the lady in red said, offering a warm smile but also giving a silent question as to who exactly Mandy and I were without saying in words for fear of being rude.
“I saw you two over here. I just wanted to get some dancing in before bringing these two over to meet you.”
“And they would be?” Catwoman asked, a smirk on her face.
“Hold you damned horses,” Beck laughed before she continued. “These two amazing women are some of my closest friends, Vicky or Vic, and Melissa.”
“Hi, I’m Vic,” the lady in red said, lifting a hand, offering a gentle, welcoming smile.
“Melissa,” Catwoman said, smirking.
“Ladies, this is Mandy and Tom, my daddy,” Beck said and smiled proudly at her announcement.
“Ho-lee shit!” Melissa said, falling back into the couch like she’d been hit. It was as if the very words of Beck’s confession were a physical force. The poor lady looked stunned, searching for something just out of reach. “You’re serious? Seriously?”
Beck just started giggling and snuggled up to my side. I didn’t know what to say, I just sat there in a mix of blindsided shock and a borderline cocky pride. Mandy started snickering at the whole situation.
“No fucking way!” Vicky said, her eyes wide as she looked from Beck to me and back to Beck again, and a huge smile spread across her face, and Beck blushed, giving the faintest of nods. “You fucking bitch! What happened to women our age should never call a man Daddy?”
“It just kind of happened,” Beck replied.
“And you’re okay with this old floozy calling your man, Daddy?” Catwoman asked Mandy.
“I think it’s really cute, but also hilarious,” Mandy replied.
“Does Rob know?” Vic asked, her eyes scanning the room.
“He just found out before we came over here.”
“Oh fuck,” Catwoman gasped, he hands coming up to cover her face up to her eyes, which were opened wide. “I bet he was pissed.”
“Jealous is more like it,” Vic snickered.
That’s when things started to fall into place in my mind. “Wait, are you saying that it was Rob who was the one who was trying to get you to call him Daddy?”
Beck sighed angrily.
“Oh, I think calling it ‘trying’ is an understatement.” Vic laughed. “Before little miss priss over here married Jeremy, she’d dated us for a little bit. It was Melissa, me, and Rob that got Beck into open relationships, and even introduced her to Jeremy.”
“Wait, hold on and back up a second,” I said, my mind spinning at all the new information. “Dated us?”
Vip wrapped her arm around Melissa, and I watched as they turned to each other and kissed. Not just a little friendly peck, a full-on, passionate, get your heart racing and blood pumping kiss.
“All four of you, together?” Vic and Melissa nodded, smiling.
I looked at Beck, who ducked her head slightly, and when our eyes met, she shrugged innocently.
“Ohmigod, you’re all in a harem!” Mandy suddenly burst out. That got everyone laughing, and Mandy blushed furiously, but the grin didn’t fade in the slightest. “That sounds like so much fun.” Now that got my attention, and my head jerked to stare at her. “What, it does sound fun.”
“First off, we’re not in a harem. We’re polyamorous,” Melissa replied. “It takes a lot of work and even more openness and communication than you would ever imagine.”
“It’s hard to keep everyone happy all the time,” Vic added. “We do a pretty good job of it, though, don’t we, Mel?”
“Mhmm,” Melissa answered, nodding.
Mandy peppered out new friends with question after question about living as a threesome or even a foursome. Vic and Melissa answered all of her questions and then some. The whole time, Beck was snuggled into my side as we watched the wheels turning in my girlfriend’s head as she listened and learned all she could.
Like the brainless idiot I was, I asked the question that was banging around in my head for the last thirty minutes without thinking. “So, what’s the big deal about Beck calling me Daddy?” I wanted to take those words back the moment they passed my lips.
Beck literally growled, and Vic and Melissa gave me a worried look. There was a horrible silence for a full minute, everyone just sitting there, no one willing to be the first to say anything until Beck murmured something under her breath before sighing and saying, “Go ahead and tell him.”
“You sure?” Vic asked, and Beck nodded.
“So, here’s the thing,” Vic started explaining. “Rob is very dominant, and if you haven’t noticed, Beck can be a little submissive when she wants to be or in the right situation.” I nodded, agreeing and following along. “He had been trying to get Beck to call him Daddy initially as a joke, but when she refused, he took it as a personal challenge.”
“So, he started pushing her. First, asking her to call him Daddy, but she wouldn’t do it. Then he started demanding it and things got a little ... ugly.”
Beck’s hands held onto mine, squeezing it tighter and tighter as Vic told the story. When Vic said things got ugly, I felt Beck flinch, her nails digging into my palm.
“Oh no!” Mandy gasped, a look of horror on her face.
“He didn’t hurt me or anything like that, not really,” Beck said, her voice low.
“While Rob and Beck were in one bedroom, Mel and I were having fun with Jeremy in another, but then we started hearing screams. Beck and Rob were yelling at each other at the top of their lungs. The three of us raced into the bedroom where Beck and Rob were fighting. Jeremy grabbed Beck and pulled her from the room. The whole time she was screaming that she’ll never call anyone Daddy.”
“Oh shit,” I said, realization of the whole thing hit me like a runaway train. I really was a fucking idiot. “I never should have asked about—”
“No, don’t,” Beck spun, sitting up and meeting my eyes. “That wasn’t your fault. Jeremy and I should have explained some of this before.”
“Rob is a fucking dick,” I replied, and I felt two sets of eyes boring into the side of my head.
“No, he’s not,” Beck told me. “It was a bad night that got out of hand. Since then, Rob and I have talked a lot about what happened, and we have both forgiven each other. So, there’s nothing for you to worry about. We’re all still friends and still have fun from time to time.”
“Nothing to worry about aside from you calling Tom, Daddy,” Vic teased, and Beck giggled. “I don’t know how you did it, Tom. But sometimes, I think I would like to find out.”
“Me too!” Melissa agreed, grinning wickedly.
“Well, what should we do now?” Melissa asked.
“That’s a good question, I have a couple of ideas,” Vic replied, looking right at me and winking. “We don’t have all that much time before the party really gets started, though.”
“What’s going to happen then?” Mandy asked, curious and bubbling with excitement. “Are they going to do another blow job race?”
“Not this year,” Vic laughed. “Though those are a good time. I’m sure there is going to be something interesting before it devolves into a full-blown orgy.”
“How much time do we have?” Mandy asked.
“Enough,” Vic answered, getting to her feet, Melissa right on her heels. Both women held out their hands for Beck and Mandy to take and helped them up onto their feet.
I stood, curious to see what Vic and Melissa had in mind. Mandy looked at me, a small smile on her face, and I pulled her to me, dropping my head so my lips were next to her ear.
“You okay with this?” I whispered and she nodded enthusiastically. “What about Rob?”
“He’s kinda cute,” Mandy said. “For an older guy.”
My head moved back at that, and I looked her in the eye and saw the little nervous smile on her face.
“You want to party with Rob?” I asked.
“Not with just him, but I won’t say no because he’s there.”
“Just remember, you don’t have to do anything you don’t want to do.”
“I know, I love you, Daddy.” Mandy giggled at my shocked expression. “I’m just kidding, calling you Daddy is way too weird, and besides, that’s Beck’s thing.”
“Would you guys be okay with coming to our rooms?” Melissa asked.
“Rooms?” Beck asked. “As in, more than one?”
“Yup, we got one of the big suites,” Vic replied, grinning. “It has a jacuzzi.”
“Why didn’t you start with that!” Beck said, and everyone started laughing. “Let’s go!”
I thought we might go straight to the room, which I was all for. I mean, how often would you get the chance to have four women all at the same time? That was a fruitless thought because our little group stopped when we got to Jeremy, Bruce, and Rob.
“We’re headed to the room,” Vic said. “You boys coming?”
All three of them looked at each other, each one with a knowing grin on their faces. It was Bruce who shocked me, however. “You all go have fun, I have a couple of people I need to find.”
“You sure?” Rob asked, “You know the girls would love another round with you.”
“Maybe later,” Bruce politely declined. “Go have fun and don’t do anything I wouldn’t do.”
“Your loss,” Rob said, before turning to his girlfriends, partners, wives? I had no idea what to call them. Rob found me watching him, and I saw him sigh and offer a small, guilty smile. “Come on, Jeremy, let’s go show these ladies a good time.”
“You don’t have to tell me twice.” Jeremy chuckled as we all started making our way to Rob, Melissa, and Vic’s suite.
Rob fell back in step beside me, Beck, and Mandy, letting his wives lead the way.
“They told you what happened?” Rob asked me, and I met his eye, nodding seriously. “Yeah, damn. I was a real asshole.” When I didn’t say anything, he continued. “Look, I know it probably seems like I am a real prick, but I’m really not. Honestly. I made a big mistake with Beck, and I regret it. Just ... be good to her. Okay? I’m not sure you realize how big of a deal it is for her to label you like she did.”
It was weird having this conversation with Rob. It wasn’t really a conversation because that would mean I was talking too. This was more of a confession, and I was still hesitant to just ignore what I’d learned. Still, I did the best I could to swallow those feelings because Beck told me everything was fine now, and she seemed genuinely okay with what was about to happen.
Rob’s suite was incredible. It was a two-bedroom suite with a living room and kitchen, and a big jacuzzi, large enough for three to four people.
“Dibs!” Beck called out, racing for the tub and slapping her hand on the ledge loudly to emphasize her point. She turned and the water and then started stripping off her outfit like it was a race. It was hardly more than moments before she was standing there in the buff for everyone to appreciate.
“Just don’t get the water all over, I don’t want to get charged for new carpet.” Rob joked, looking at the jacuzzi and then making eye contact with Beck.
Shit, he’s got a point. I looked around for a solution to the problem that was guaranteed to happen at some point. Using my ever-eternal brilliance, I grabbed the towels from the bathroom and started rolling them up and setting them on the floor, creating a makeshift dam to keep any splashing water off of the carpet.
“Oh, that’s good thinking, Daddy!” Beck grinned as she climbed into the tub and sank to her neck in the hot water. “Hey, guys, where are the jets?”
“There’s a knob on the wall,” Vic called out in answer.
“I’ll get it,” Mandy offered, her dress pulled down off of her shoulders and bunching around her waist. Her breasts jutting proudly from her chest as she moved to the controls, and then the low hum of the air pumps kicked on, and as if by magic, the water bubbled and frothed majestically.
“Ahh, that’s nice!” Beck moaned, sinking down to her chin in the water.
