We were waiting in the queue for the next game to start when we heard footsteps upstairs and then the sound of our moms’ voices.
“I think they’re done,” Danny said, looking up at the ceiling as if he could see right through it and up into the kitchen area.
“Maybe...” Leah replied, her head tilting slightly like a dog who’d heard something interesting.
“They were out there for quite a while,” I offered. “You guys wanna go check?”
“I mean, sure,” Danny replied, looking right at me. “As long as it’s still my turn if they aren’t done yet and we have to come back down here.”
“Fine by me,” I shrugged and looked at Leah.
“Whatever...” She rolled her eyes, getting up from the couch, stretching before starting to walk towards the stairs. “Come on, let’s go see what’s going on.”
Danny and I jumped up and hurried after Leah, who giggled when she realized we were chasing after her. We reached the kitchen as a group and found our mothers just standing there watching us with interested looks on their faces.
“What’s the hurry?” Ellen asked. “You three are running like there was a fire or something down there.”
My mom started laughing when all three of us came to a stop, wide-eyed, not expecting to see our moms just waiting for us like that.
“Did you three forget how to talk?” Ellen asked, this time making it obvious she was teasing us.
“What?” Danny said, his face scrunching up like his mom had just said something ridiculous. “No.”
“Okay, so why were the three of you in such a hurry?”
“Come on, Ellen,” my mom said, smiling brightly. “You know why they’re up here. They want to get in the hot tub.”
“Oh, is that what it is?” She gave us a questioning look.
“Yup, that’s exactly what we were thinking,” Leah answered, offering a confident smile of her own to the older women of her own.
“Well...” Ellen smirked dangerously, giving me pause. “Come on out then, the water’s great, and the show’s been steamy!”
“Umm...” I hesitated, my face flushing at the not so hidden meaning behind her words, and my mom burst out laughing.
“She’s just teasing, don’t listen to her,” my mom said, slapping Ellen’s ass playfully, who shrieked at the sudden impact, which made Leah, Danny and me laugh. “The show’s over for the night.”
“You’re going to get it for that!” Ellen glared at my mom, but there was real danger in those words. “And who said there isn’t an encore?”
“We both know there isn’t.” Mom snickered, and Ellen grinned proudly. “Do us a favor and grab four beers from the fridge and take them out with you, please. We’ll be out in a minute.”
“Hey guys,” Scott called out when he noticed us walking out onto the deck. “What are you--- oh, you brought beer!”
“Beer?” My dad asked, spinning in his seat to look over his shoulder at us. “Hey kids, where’d your moms go?”
“No clue.” Leah shrugged. “They told us we could join you, as long as we brought you something to drink.”
“And what, might I ask, did you bring us to drink?” my dad asked inquisitively.
“Beer!” Danny said, holding up the two beers he had in his hands, while I did the same with the two in mine. “Ice cold beer.”
“Well, don’t just stand there...” Scott stood up, his waist coming fully out of the water as he waved us over, a huge smile on his face. “Get the hell over here with those and jump in the damned water already.”
Leah giggled at Danny’s dad’s excitement over a couple of beers, and I couldn’t help the grin that spread across my face as well. Danny didn’t waste a minute, though, scurrying over and climbing into the tub, handing one of the beers in his hand to his dad before giving the other to my father.
“Lucas, you can leave those on the ledge,” Dad said, as Leah and I climbed into the water. “Unless you want one?”
“Really?” My eyes went wide. “Can we?”
“No.” My dad laughed. “Sorry, kiddo, but you’re way too young to start drinking beer.”
“Beer’s gross.” Leah made a disgusted face and immediately shook her head at the very idea of tasting the beer.”
“Damn right it’s gross!” Scott agreed, grabbing Leah’s attention, who spun to look at him, smiling.
I frowned at my dad, who offered an apologetic smile. I ended up setting the ice-cold cans down where Dad had originally suggested before sinking down in the water on the far side of the tub, my arms crossed and pouting.
“If you had drunk one of those,” Leah whispered into my ear. “I wouldn’t have let you kiss me later.”
That got my attention, and I turned to look at her and saw her smiling face looking right at me.
“Charles, you know what?” Scott said.
“What?” my dad replied.
“I think you figured out the secret of having two kids, a boy and a girl, and not having them want to kill each other all the time, let alone like each other.”
“Twins.” Dad grinned proudly.
“Damn right!” Scott nodded. “I wish Danny and Jez were as close as Lucas and Leah are. That would make life and other things a whole lot easier. You know what I mean.”
My dad looked over at us for a moment, seeing Leah smiling at me and the two of us genuinely happy to be next to each other. Then he looked back at Scott and nodded, “Yeah, it definitely would, no question.”
There was a hidden meaning in Scott’s words that I didn’t get. I looked at Leah, who didn’t have a clue. We both looked at Danny, who, for whatever reason, blushed but covered it up, while he tried to defend himself and his older sister.
“Jez and I get along,” Danny said.
“Not like those two,” Scott replied, smiling at the two of us.
“Ahh, I see the kids decided to join us,” my mom said as she and Ellen stepped out of the house and walked over to the edge of the hot tub.
“Sure did, and they brought refreshments!” Dad replied, grabbing one of the cans of beer and handing it to our mom.
“Thanks, honey,” Mom replied, smiling as she climbed into the water and taking a seat right next to our dad.
“What about me?” Ellen asked, looking dejected that my dad hadn’t handed her a beer.
“Get your own, Mrs. Steamy,” Mom replied, leveling a glare at Danny’s mom.
“Mrs. Steamy?” Scott asked, looking at his wife in confusion.
“That sounds like an interesting story...” My dad grinned, leaning forward, interested in what Ellen was going to say.
“It was just a joke,” Ellen smiled, grabbing the last beer, and then climbing into the water and sitting in Scott’s lap. “I was teasing the kids about running through the house. Beth and I were in the kitchen and then heard the kids running up the stairs from the basement.”
“They were wanting to get in the hot tub,” my mom cut in, drawing our eyes away from Ellen.
“Let me tell the story,” Ellen said, shifting everyone’s attention back onto her.
“Fine.” My mom waved to Ellen. “Go ahead.”
“Thank you.” Ellen smiled, shifting her position on Scott’s lap, eager to finish her story and excited to tell it. “As I was saying, the kids came racing up the stairs, probably thinking we were getting out of the hot tub, and thought it was their turn, right Leah?” She looked right at Leah, who grinned bashfully but nodded her agreement. “So, we told them that they didn’t have to wait and could come join us in the tub. I might have alluded to the show being a bit steamy.”
“Oh my.” My dad’s eyes brightened for a moment before a smirk formed on his lips.
“It is pretty steamy in here.” Scott chuckled, looking around the tub and moving his hand around the water as if he were testing the temperature. “Unfortunately, a lot less so now,”
“Scott!” my mom hissed, her face flushing as she gave me and Leah a sideways glance.
“What?” Scott shrugged. “It’s true.”
“She wasn’t referring to ... umm...” Mom blushed furiously, finding herself caught in a game of word play that she wasn’t prepared for. “ ... How hot the water is.”
“I think it’s safe to say the kids have known what the four of us are doing out here in the hot tub for quite a while,” Ellen said, looking at Danny, and then at my sister and me. I looked over at my parents, who were trying to hide the mortified looks on their faces as Ellen all but confirmed that we knew what our parents had been doing for years every Friday night. “They aren’t those innocent little kids anymore that we could just send to bed when it got dark.”
Leah and I didn’t react to Ellen’s words. Danny, however, grinned and nodded.
“We’ve known for a long time,” Danny announced proudly.
“What?” My mom gasped. “Seriously?” Her eyes found Leah and me. “I mean, I know you knew, but for years?”
“I don’t know how long we’ve known, but we know.” Leah smiled nervously, and Mom’s eyes went wide as the color in her cheeks deepened severely.
“Oh. My. God!”
“It’s just sex, Mom,” Leah quickly tried to calm our mom down. “It’s not that big a deal.”
“Sex is always a big deal,” my dad quickly answered, his voice sounding almost gruff at how his daughter had just downplayed the meaning and importance of sex in general.
“I’m not saying that having sex is no big deal,” Leah quickly tried to correct what she’d said.
“Honey, sex is a very big deal,” Mom said, her voice in complete contrast to Dad’s. Where Dad was upset, Mom was soft and gentle, loving. “Sex is special, and it needs to be with someone special to you, who loves you and respects you.”
“Mom...” Leah blushed. I could feel her wiggling next to me nervously. If the bottom of the tub hadn’t been lit, I would have reached out a hand to her. As it is, everyone could see everything under the surface, so I didn’t move.
“Don’t just ‘Mom’ me.”
“I think she knows, Beth,” Ellen cut in.
“I’m just making sure,” Mom replied. “What the four of us do is not just a game. We all care for each other and have for a very long time, since before you two were born.”
“We know,” I finally joined the conversation. “I think what Leah was trying to say was that for you guys, sex isn’t that big of a deal, because we know how close you all are.”
“See, Beth, Lucas is absolutely right,” Ellen said, with a somewhat relieved look on her face as she shifted her gaze from me to my mom.
“Well, now that we can’t just pretend they’re ignorant of our shenanigans,” Scott said, looking surprisingly happy that what they’d been doing was all out in the open now. “How long have you three known?”
“Umm...” I stammered, not sure how I should answer that to avoid having my mom’s ire turned on us, and then Leah telling them what we’ve been doing for ages now.
Danny didn’t have such worries, “Seriously Dad, almost every time we came back from swimming, we’d have to sneak under the deck, and I know this is going to come as a shock, but you, Mom, and the Stevens aren’t exactly quiet, if you know what I mean.”
I don’t think my parents’ faces could have been any redder than they were at that moment. I mean, my dad’s face was beet red. Mom’s wasn’t any less reddened, but the fact she was trying to hide her face in Dad’s shoulder made it all that much worse.
“I told you!” Scott laughed, playfully pushing his wife next to him. “You’re a screamer.”
“I am not!” Ellen scowled at her husband, who was grinning like an idiot.
“You are pretty loud, El,” my mom said, agreeing with Scott, and immediately started giggling, hiding her smile behind her hands as she leaned into my dad protectively.
“I know you’re not trying to say it was me that they always heard,” Ellen fired back defiantly. “I can’t help it that Charles and Scott know how to push my buttons. At least I’m not the one saying the nasty things like—”
“Oh, don’t you dare say anything more!” Mom jumped up, cutting off Ellen’s words, her full, firm tits bouncing with how fast she got to her feet, and the water cascaded down her body.
“What did you think I was going to say?” Ellen smirked knowingly, her eyes drifting over to Leah and me before refocusing on our mom.
“You know,” my mom said, her voice now laced with a hint of panic.
Ellen grinned even wider at Mom’s words. “I wasn’t going to say anything about those things, not yet anyway. Besides, if they heard me, I’m pretty sure they’ve heard you too.”
Mom’s eyes widened at that, and her mouth slammed shut so hard her teeth clicked before she sat back down, stunned.
Leah and I just looked at each other, not sure what Ellen was talking about. Danny wasn’t exactly telling the full truth, which he couldn’t, but what he did say made sense and stopped any further questioning from his parents or mine. There were plenty of times we’d sneaked into the basement and heard them having fun in the water above us, but that wasn’t at all what told the three of us what was going on.
“Why don’t the four of us take this conversation inside and leave the kids to enjoy the water for a while?” my dad suggested, standing up in the water. When he did stand, it was immediately evident that his cock was not soft. He was only half hard, but it was a sight Leah, and I weren’t used to seeing.
Leah’s eyes honed right in on it, and she giggled.
“What’s so funny?” Dad asked, confused.
“Umm, you’re hard,” Leah replied, pointing right at our dad’s cock.
“Seriously,” he replied, but moved his hands to hide the evidence. “It’s not like you’ve never seen an erection before.”
“Oh, I definitely have!” Leah snickered. “Lucas and Danny get hard any time the wind blows.”
“Then don’t act like it’s a big deal.” Dad tried to play it off like it was normal, and he was doing a darn good job of it. Dad still had the random erection, but they were few and far between and almost exclusively first thing in the morning. I couldn’t remember the last time he had one while we were in the hot tub with him, however.
“That’s kind of too bad,” Ellen joked. “Your dad’s dick is pretty darn impressive when he’s hard.”
“Ellen!” my mom hissed.
“What?” Ellen replied. “We’re nudists, it’s not like she hasn’t looked at her dad’s cock a million times.”
“I mean, that’s not the point...” Mom’s voice trailed off.
“I think Charlie has the right idea, let’s head inside,” Scott said as he got to his feet as well, however, he was completely soft. “Come on, ladies, maybe something fun will come up while we’re inside.”
“That was terrible,” Ellen guffawed, slapping his shoulder.
