We sat at the dining room table and Mom brought in the meal. Marty, if anything, was a hell of a storyteller. I liked him, really liked him. I think I did from the very moment Dad opened the front door, and I saw him standing there in his sunglasses, Hawaiian shirt, and flip flops. He seemed like he didn’t have a care in the world.
“Okay, so what makes it so unique?” Leah asked, unable to hold herself back.
Mom and Dad’s facial expressions were of utter astonishment at my sister’s brazenness, but Marty just laughed.
“I like you, Leah,” Marty said after his laughing tapered off, wiping his eyes and still chuckling. “You remind me so much of my wife. She absolutely hated secrets. She needed to know everything. If she were here right now, I’m sure she’d love you too.”
“Thanks.” Leah smiled, but feeling emboldened by Marty’s words, didn’t hesitate to ask, “So, what’s so unique about Sapphire Cove?”
“You,” Marty replied simply, and let his answer hang in the air.
“Me?” Leah scrunched up her face in confusion. “I’m not there. How would I be the one who makes it so special?”
Marty just grinned.
“Come on, Marty!” Leah whined. “Please!”
“Alright, since you asked so nicely.” Marty chuckled at my sister’s obvious impatience. Mom, Dad, and I didn’t dare say a word. The three of us were waiting with bated breath for what Marty was going to say next.
“When I said you, I meant a little more than just you being there,” Marty said.
“Obviously...” Leah rolled her eyes.
“Quite right!” Marty grinned. “Let me tell you a secret...” Leah smiled at that and leaned in anxiously. “I was a twin, too.”
“What?!” Leah gasped. “Really?”
“Mhmm.” Marty nodded solemnly. “My sister and I were extremely close growing up. We were truly inseparable.”
“Wow...” Leah said, stunned at what she was hearing. Her face colored and she asked him, “Did you two...”
“Oh, yes.” Marty grinned.
“Holy shit!” Leah exclaimed both shocked and elated.
“Leah, language!” Mom barked.
“It’s okay, Beth...” Marty turned to say over his shoulder. “At least the girl’s honest.”
“I mean...” Mom stammered, her face flushing, not sure how to react to that.
“You know, Leah,” Marty said, keeping his voice low, like he was about to tell her even more secrets. “It takes a twin to really and truly understand another twin.”
I didn’t need to be sitting across from him to know he knew. I don’t know how, but he just ... knew, without having to ask. Like he could read her like a book, and everything we’d done was right there on the pages for him to take in at his leisure.
“Am I right?” Marty asked. And Leah nodded slowly, with deathly seriousness on her face. “So, you asked me what makes Sapphire Cove special?” Leah nodded again. “It’s that.”
If Leah’s eyes had gotten any wider, they would have fallen right out of her head.
Both Mom and Dad looked at me, and then at Leah. I could see the wheels turning in their heads, but the pieces had not yet clicked into place.
I moved over to stand next to my sister, placing my hand on her shoulder as I got there. She gave me the most loving, wonderful smile I’d seen on her face in years.
“We’ll...” I looked back down at Leah, who reached up a hand so that it rested on mine. “ ... be okay,” I said, more of a statement of fact than a question.
“Yes.” Marty nodded.
“Oh!” Mom suddenly exclaimed, and all eyes shifted to her.
“What?” Dad asked, confused.
“It’s ... they’re ... oh God!” Mom’s mind was moving so fast, her tongue couldn’t keep up, but there was a look of relief on her face.
“Wait...” Dad glanced around the room to see everyone grinning. “Someone explain what the heck is going on, please?”
“Let me make it plain for you, Charles,” Marty said, turning in his chair so he was facing my dad. “The relationship your children share isn’t a problem for the people who live in Sapphire Cove.”
“How do you know—”
“Don’t worry about how I know, just know that I do,” Marty replied, his voice subtly firmer. “What they share ... will be accepted freely. It’s not something everyone is doing, don’t get me wrong, but they won’t be the only ones.”
Dad looked like he was going to pass out, but Mom was all smiles. Not that she approved of everything, but that her kids’ secret wasn’t going to be something that was going to hurt them.
“What about us and the Griffins?” Mom asked nervously.
“Oh, ho! I thought you’d never ask!” Marty grinned widely. “I think you’ll be very happy to find out that almost everyone at the Cove is quite open to swinging and exploration. We are all very open-minded, thank goodness, but that’s what makes it work, and why people love it. There are so many different ways of life and love, as you’ll see for yourselves soon, I hope. You’ve got nothing to worry about there.”
I don’t know if Mom was more relieved at that, or the fact that Leah’s and my relationship wasn’t a problem with Marty.
“Do you mind if we ask a few more questions?” Mom said, taking a seat at the table.
“Sure.” Marty smiled, leaning back in his chair. “I’m an open book.”
“How did Sapphire Cove come to be?” Dad asked.
“Well, that’s a bit longer of a story,” Marty replied. “You see, my parents started it a long time ago. They just wanted a place to be themselves and raise their family the way they wanted to. Who knew so many people wanted the same things we did? Over time, we slowly started allowing people in. We were very protective of our family, and by extension, the new families as well. It grew and grew. It was a slow process, but it’s led to what the Cove is today.”
Marty sighed, rubbing his stomach.
“I think I ate too much,” he complained, and then looked around the room warmly at me, and my entire family. “I guess we should get on to business then...”
It was official, it was actually happening. We were formally invited to move to Sapphire Cove!
The one issue we had was that there was limited housing. To help control how many people lived there, new families were only allowed to join when the older ones left. That brought its own set of complications because families didn’t just leave Sapphire Cove. The only other way was when a new house was built. From what Marty explained, the house the Griffins chose was one of the new ones that had recently been completed. That wasn’t the only new one, however. A second one had been built right next door!
Marty made a quick phone call to Scott while we were all sitting around the table. When he heard the news that we’d been officially invited, he started yelling celebratorily through the phone loud enough that all of us around the table could hear him, forcing Marty to hold the phone at arm’s length from his head. The smile on the old man’s face was hilarious and got Leah and me laughing while Mom and Dad just smiled brightly at hearing the excitement of their friend as he learned we were coming.
That’s when things really got moving. Marty explained that Scott had taken it upon himself months prior, with Ellen and the kids’ help, to get our new house taken care of. He’d known, or rather, hoped we’d agree to move. He just couldn’t say anything because of the whole secretive nature of everything. Judging by the way people lived in Sapphire Cove, there was a good reason for that, too.
There were things we needed to do, but that was all on the financial side for Mom and Dad. The rest of it, apparently, had been taken care of by the Griffins. Leah and I were clamoring for pictures, so we could see the house that had been picked out for us. Marty had chuckled, pacifying the two of us, by saying there would be more than enough of those, and they would be sent to our parents for final approval. When we pressed for more information, he refused to give us even a hint, just smiling coyly and promising that we’d love it.
Marty left in the early evening, claiming he needed to get back on the road. We all said goodbye with Mom and Leah offering him big hugs, much to his delight, while Dad and I shook his hand, telling him we’d see him soon.
After we’d all watched him drive away, Leah started squealing like she’d just won the lottery, jumping up and down, pumping her fists over her head in triumph. Dad just chuckled as he watched her, and Mom flushed happily, wrapping her arms around Dad and resting her head on his chest as she watched Leah celebrate.
The first thing Leah and I did after that was rush downstairs and try to find Danny to tell him the good news, but again, he wasn’t online.
“Where the hell is he?” I groaned.
“No clue...” Leah shrugged. “I don’t really want to play, though; can we watch a movie or something?”
“Sure!” I grinned, setting down the controller and grabbing the remote, and turning on Netflix. “What do you want to watch?”
“I don’t care, just something funny,” Leah replied before pushing me over. I chuckled and allowed it to happen. I knew what she wanted ... snuggles.
As soon as I was on my side, my head lying on the armrest, she lay down in front of me, pushing her entire body back so that it was flush against mine. She grabbed my other arm, wrapping it around her before sighing contentedly.
We had already finished two movies, and Leah was searching for the next one when Dad came down the stairs.
“Are you too decent?” Dad called out.
“Dad!” I groaned and looked up to see him peeking around the corner and looking down at us on the couch.
“What?” Dad smiled innocently. “I was just checking.”
“You’re such a dork sometimes, Dad.” Leah giggled, making him grin.
“Your mom and I would like to know if you want to come sit in the tub with us for a bit,” he said. “We aren’t tired enough to go to bed, and we thought maybe a nice soak would help. I assumed you two couldn’t sleep either.”
It didn’t feel that late, but when I looked at the clock, it was already midnight. There’s no way it was that late, I thought. Still, I was just fine staying where I was and snuggling with Leah. So, I was about to refuse Dad’s invitation, albeit politely, but Leah beat me to it. “Sure, now?”
“Yup, your mom’s already out there waiting.”
“Alright, let’s go!” Leah said, rolling off the couch and out of my arms before jumping onto her feet and actually running right past Dad and up the stairs.
Dad gave me a questioning look, and I just shrugged and rolled my eyes; what else was I supposed to do?
I got in the hot water ahead of Dad, sliding in next to Leah, who smiled brightly at me. Dad was the last one in, and just as he sat down, Mom grabbed my dad’s face between her hands and planted a solid, passion-filled kiss right on his lips. Leah and I started snickering as we watched from across the tub.
Their kiss lingered, lasting for longer than normal. Mom wasn’t just unable to sleep; she was fired up, apparently. Then she started making little noises, the same type of noises Leah would make when we got into a hot make-out session.
Leah started giggling as she watched our parents making out.
I don’t know if they just got too worked up and forgot that we were there, but their kiss deepened further and further until Dad grabbed Mom’s waist and pulled her into his lap. She laughed at the sudden movement, pressing her chest into his, and his hands moved down and were now tightly gripping her ass.
Leah sucked a loud intake of breath, her eyes wide. I glanced over at her, and she mouthed, “Ohmigod.”
I nodded in agreement, my own eyes wide at the scene unfolding only a couple of feet in front of us.
“Do you think they even remember we’re still here?” I whispered, smirking. Leah just blushed and snickered behind her hands.
My question was answered when Mom finally pulled away from Dad, just enough that she could twist and look over at us.
“Why don’t the two of you--Oh!” Mom’s eyes went wide, and Leah and I saw Dad take Mom’s breast in his hand and stuff the nipple in his mouth. “Charles not in front of ... mmm.”
Leah looked over and me at the same time I looked at her, we both started snickering, and I felt Leah’s hand slide into my lap, and her fingers wrap around my shaft.
“What are you doing?!” I hissed quietly, worried Mom or Dad would look over and see what she was doing.
“What?” Leah replied. “It’s not like they don’t know...”
That stopped any complaint I had immediately, and I just grinned as Leah’s eyes danced with mirth.
So, tit for tat, I reached a hand down on top of her thigh, which she shifted to allow enough room for my hand to slip between her legs. Even being underwater, I could feel the slick wetness of her pussy. For that to be the case, she had to be insanely turned on.
“Jesus, Charles...” Mom’s head fell back as she moaned. It looked like something far more interesting was happening or had just happened than just Dad sucking on Mom’s nipples. “The kids ... the kids are here...”
From the way they were sitting in the water, we couldn’t see exactly what that was, but we didn’t need to see it to have a pretty good idea. Mom’s hips started to rock, and not just little movements either.
Dad’s head leaned over to the side, looking past Mom and right at us. His eyes widened in realization.
“Time for you two—” Dad grunted, gritting his teeth as his eyes looked up and Mom. “You two need to get out and—” Dad grunted again, and Mom moaned. “Give your mom and me some time alone.”
“But—” Leah started to argue.
“Get out!” Mom’s head spun, her eyes hot and intense.
The three of us stared at each other for a breath, her eyes seeing everything in that moment, Leah’s hand on my hardness, stroking me under the water, and my own arm reaching between Leah’s legs. There was something in the way she was watching us that felt different. Like she was interested, but before she could say something else or mention it in some way, Dad did something, and Mom’s eyes rolled up in her head, breaking the moment.
“Come on, I need you,” I said softly, but urgently.
“Mmm, let’s go.” Leah grinned, releasing my cock and climbing out of the water. I normally would have been hesitant to let my parents see me with a full-on, throbbing erection, but right now, I couldn’t have cared less. I got out, my cock waving in front of me as I did so.
“Come on, let’s go up to my room,” Leah said, and I grinned and nodded. She took my hand and pulled me after her, impatient to pick up where we left off.
Leah pulled me through the open door and then spun, kissing me soundly in the middle of her room. We’d rushed in so quickly that closing the bedroom door wasn’t even a thought. Not that it mattered, Mom and Dad were going to be busy for a bit, so we didn’t have to worry about being found out. Then again, from what both our parents had seen in the hot tub, they knew what was going to happen.
I took the lead as we made out, our hands roaming each other’s bodies frantically. Both of us were grabbing, squeezing, rubbing anything we could get our hands on. When I dropped my hands to her ass, cupping it and pulling her close, she moaned as the kiss became wild and reckless. But as fast as the kiss started, it ended just as abruptly.
Leah tried to pull back, but I didn’t move my hands from her ass. She might have wanted space to breathe, but I sure as shit didn’t. I was painfully hard, my cock needily bobbing up and down in phase with my heartbeat. When Leah realized I wasn’t letting her go, her eyes flashed, and she pushed me, hard, and we both started to fall. I released my hold on her ass to catch my fall, not sure exactly where I was going to land. My back hit the mattress, but my head slammed into the wall with a loud thump.
“Ow!” I complained, my hand coming up to grab the top of my head.
Somehow, Leah managed to stay on her feet and looked down at me with a startled look on her face.
“Sorry...” Leah winced, pausing for a second to make sure I was okay.
“Damn, that really hurt...” I replied, still rubbing the top and back of my head.
“Can I make it better?” Leah asked, her words filled with unspoken meaning, and I grinned.
“What did you have in mind?”
“I’m not going to tell you...” She smiled down at me, moving towards the bed and climbing on, crawling up so that her knees were on either side of my legs, her hands on my chest, holding her so that she was hovering just over me. “But I’ll show you.”
My eyes locked on Leah’s, and everything seemed to move in slow motion. First, her face came down, her lips meeting mine again. This time, however, the franticness, the passion-filled craziness of it was gone. This was now controlled, slow, and deliberate, something we’d rarely, if ever, experienced together.
Her eyes closed a moment before her lips gently brushed across mine. It was hard to restrain myself. The need in my groin was still burning white hot, and all I wanted to do was grab her forcibly and flip her over on the bed so that I was in control. I tried to calm my breathing and give myself a chance to enjoy whatever it was my sister was going to do or show me.
Our kisses were fleeting meetings, our lips touching and parting over and over. When I felt Leah lift, I opened my eyes to see her looking down at me with a look in her eyes I hadn’t seen before. There was a passion and desire there, but it also looked like she was trying to hold it back for some reason that I didn’t fully understand.
“Don’t move, okay?” she asked softly.
“Okay...” I nodded, watching her intently.
“You promise?” Leah asked, her eyes searching mine for the truth in whatever answer I was about to give.
“Sure.” I smiled up at her, and her eyes narrowed.
“I’m serious, just please, don’t move.”
“Alright, okay, I won’t, I promise.”
“Good.” Leah smiled brightly, her eyes twinkling. “I love you, thank you.”
“I love you, too.” I craned my neck up, trying to reach Leah’s lips for a kiss, and held it there, lips puckered and waiting.
“You’re such a dork.” Leah giggled, making me grin widely before she gave me a quick peck.
My head dropped back down to the mattress, and I watched as Leah reached an arm down between us and took my cock in her hand.
“Mmm,” I moaned, feeling the warmth of her fingers on my shaft, and my dick jerked.
“Don’t move.”
“I didn’t!” I replied.
“Okay...” Leah bit her lip nervously. “I just felt you twitch.”
“Sorry,” I said. “I can’t help that.” Which was true, there was nothing I could do to stop that from happening when I was this keyed up.
“I know, I’m just nervous,” Leah said. I was going to say something else, but what she did next made me forget what I was about to say.
Leah angled my cock so that it was pointing straight up, and she lowered herself down until I felt her folds open, parting around the tip. If she’d had placed me a bit further back, I would have been inside of her, I was sure of it. But she had me just under the hood of her perfectly smooth clit.
“Oh, you feel so warm against me like that,” Leah said, her eyes closing as she held me there.
