“Jordyn, umm...” I paused, trying to figure out how I wanted to phrase my question. “Why are you being so ... I don’t know how to say it...”
“Slutty?” Jordyn said, using the exact word I wanted to, but was too afraid to voice because of the potential consequences.
“Well ... yeah?”
“Jesus Christ, Lucas!” Leah hissed. “How could you think she’s—”
“Why not?” Jordyn replied, cutting off my sister, smiling as she snuggled into me. “What we did was pretty naughty.” Jordyn’s cheeks flushed and her eyes danced with mirth as she looked at me. “If you want my honest answer, it was because I was worried that if I just lay down and let you take my virginity before, you’d think I was a slut. But not only that, I was scared I wouldn’t be any good.”
“What!” Leah gasped. “Seriously?”
“Yeah, duh.” Jordyn rolled her eyes dramatically before starting to giggle.
“How could you not be any good?” Leah replied, a stunned, confused look on her face. “Have you seen yourself?”
“Of course I have,” Jordyn replied. “But having big tits doesn’t mean anything.”
“It fucking helps,” Leah muttered half under her breath and Jordyn grinned.
“You didn’t have anything to worry about,” I said, keeping my voice low and steady as I looked her in the eye. “You’re amazing and you feel incredible.”
“Mmm, so do you.” Jordyn sighed, resting her head on my chest.
The three of us lay there for a while before anyone decided that we should probably get up, or else Mom and Dad were bound to come and see what was going on.
“They aren’t going to come up here,” Leah said, waving off the mere idea that we might get caught. “Besides, if they do, we aren’t doing anything.” Leah grinned. “Not anymore, at least.”
That little statement got both girls giggling, and I grinned like an idiot along with them. Still, I needed a shower. Jordyn needed a shower more than I did, though it seemed like she wasn’t in a hurry to wash off the remnants of what we’d just done.
“Jordyn, let’s go to my room,” Leah suggested eagerly. “I want to know everything. Every single thing about what that felt like.”
“I bet you do!” Jordyn giggled, running her fingers through her slit again and feeling what was left of my come on her mound. “Let’s go!”
When the two giggling girls raced into Leah’s bedroom, I hit the much-needed shower.
After I finished drying off, I walked down to the kitchen with a definite, obvious bounce in my step. I was feeling so good that I thought nothing would be able to ruin my day after such an amazing start. I mean, Leah, me, and Jordyn ... in my bed ... sex ... holy shit! I had just hit the landing at the bottom of the steps and veered towards the kitchen when I was stopped in my tracks.
“Lucas, come and sit for a minute,” Dad said. His voice wasn’t harsh, but I felt an icy chill run down my spine hearing it. “Your mom and I want to talk to you.”
I tried to act normal, putting on a smile as I walked into the living room where Mom and Dad were sitting on the couch. They didn’t look angry, but there was a weird-looking grin on my dad’s face; both his and Mom’s gazes followed me as I walked across the room and sat down in the recliner across from them.
There was an uncomfortable silence as I sat there looking at my parents, and they just stared at me. I started to fidget nervously and suddenly felt hot as my mind started to race. The answer was obvious, they knew. They fucking knew what was going on in my room. Shit!
“Interesting morning,” Dad said.
“Umm...”
“Alright, let’s drop the act,” Mom cut in. “I found it interesting that I was the one who let Jordyn in, and she headed straight for your room.”
“I didn’t know she—”
“Oh, we know. The corners of Mom’s lips twitched for a moment, giving away the slightest smile before she schooled her face again. “Jordyn said she was early and wanted to surprise you.”
“Oh...” My cheeks heated, and I quickly dipped my head to hide the blush on my face and the sweat that was starting to bead up on my forehead.
“I thought it was cute and sweet,” Mom continued. “Imagine my surprise when some very interesting noises came from your room after that. After, I might add, your sister joined the two of you in your room.”
“Oh, man!” I brought my hands up to cover my face.
“You aren’t nearly as sneaky as you like to think,” Mom said.
That raised a lot more concerns than just me having sex with Jordyn in my room. Did Mom and Dad know about me and Leah? That was a scary thought. I mean, twins are traditionally very close, but there are certain lines that weren’t supposed to be crossed, at least according to the general public. Leah and I ... we hadn’t just crossed them; we danced and partied as we crossed them, over and over, for years.
“Look, Lucas,” Dad said. “Sex is a very big deal, and we just want to make sure you understand exactly what you’re doing, and the responsibilities that come with being intimate with someone, especially at your age.”
“Why do you think we were having sex?” I asked, praying that they were guessing and didn’t actually know for sure.
“Really?” Mom chuckled. “You really think your father and I don’t know what sex sounds like? Come on, you’re smarter than that.”
“I know,” I replied softly. “I just—”
“Do you?” Dad asked. “Do you really know?”
“Yes.” I nodded and then paused nervously when the look on Dad’s face didn’t change, making me feel like I wasn’t so sure anymore. “I ... think so.”
“You think so?” Dad echoed me, not sounding pleased at all with my answer.
“Lucas, look at me,” Mom said, her voice taking on a soft, caring tone. I lifted my head until our eyes met. “Remember when we talked before about Jordyn and hurting her?” I gulped and nodded. “Don’t you think it’s a bit unfair to do what you two did this morning, especially since we’re hopefully moving soon?”
“We talked about it...” I swallowed, my mouth feeling bone dry. “ ... and she wanted to ... you know.”
“So, what now?” Mom asked. “What if she thinks you’re going to be her boyfriend now? Did you think about that?”
“She knows we can’t,” I replied, reluctantly, but Mom picked up on the hidden meaning behind my words.
“She knows we might be moving?” Mom asked, her voice sharp and intense.
I nodded jerkily, thinking that was what she wanted to hear, but the look of disappointment and shock on her face told me otherwise.
“You told her?” Dad asked, eyes wide with surprise.
I shook my head slowly, “No, it wasn’t me. Leah ... kind of let it slip when she was arguing with Nik.”
“What?” Mom hissed. That softness she’d shown a moment before was gone. “What the hell were they arguing about that she’d even think about telling them about that?!”
I gave my parents a pained look, hoping they wouldn’t ask me why she’d spilled the beans. That was a conversation that was, no doubt, going to get really awkward, really quickly.
“We can talk to her about that later,” Dad said, resting his hand on Mom’s leg, calming her. “Lucas, do you think you’re mature enough to handle sex?”
“Yeah.” I nodded.
“Good.” The corner of Dad’s lip lifted in a smirk. “Sex is not a bad thing. It can be incredible with the right person or people.”
“So, where did you get the condoms?” Mom asked, looking genuinely curious.
“I umm...”
“Lucas!” Mom gasped.
“Wait, you didn’t use a condom?”
“No ... I thought—”
“No, that’s the problem, you didn’t think!” Dad sighed, throwing up his hands. “You always, always need to protect, not only yourself, but your partner. Do you know if she’s on birth control?”
I shook my head no, panic forming a knot in my stomach.
“Honey, did you finish inside of Jordyn?” Mom asked with a straight face.
I didn’t know what to do with that. The last thing I thought I would be asked about was if I came inside of Jordyn’s pussy. I sure as hell didn’t think it would be my Mom doing the asking.
“Well, did you?” Mom asked again. “Or did you pull out before you came? Some girls like that.”
“Ohmigod, Mom...” I was going to pass out; I was sure of it.
“What, it’s true.” Mom snickered at my glaringly obvious discomfort.
“If you’re old enough to have sex,” my dad said, “then you’re old enough to talk about it honestly.”
“I umm ... yes, Jordyn wanted me to come inside of her,” I answered, my face felt like it was on fire, my heart was racing, and it was getting hard to breathe.
“So, now Jordyn’s walking around with your overeager come inside of her young, ready to breed pussy.”
“Jesus Christ!” My face was ashen. That was an image that felt all kinds of wrong.
Then Mom and Dad started laughing. What the fuck was going on?!
“Lucas, your mother, and I aren’t upset that you had sex. We just wanted to make sure you really knew what you were doing.”
“Lucky for you,” Mom added. “I know Jordyn’s on birth control. She’s been on it for months now. I talked to her mom about Leah, and she told me all about it.”
“Oh, really?” My head jerked up, a look of surprise on my face, and I thought my heart might have skipped a beat or two, but some of the anxiety that had been threatening to cripple me receded.
“No, honey.” Mom chuckled, and Dad grinned wider. “You don’t need to hide the fact you’re having sex, not that you could with how vocal some people are. We’d rather you be open and honest about it. That way, we know you’re safe and so is everyone else.”
“Okay.” I smiled weakly.
“Also, if you have any questions about how to do certain things, like making sure she enjoys it as much as you do, we’re both here and can help.”
“That sounds so ... weird,” I replied. The other thing that was weird about this whole conversation was that Leah hadn’t been brought back up after Mom said she saw her coming into my room. I didn’t dare bring that fact up, just in case they’d forgotten about it, but I highly doubted that was the case. Still, I left it alone.
“Go on,” Dad said, waving me off. “Go get something to eat, I’m sure you’re starving.”
Just then, my stomach rumbled loudly, and I flushed as Mom and Dad started laughing again.
“After you eat, don’t forget to strip your bed so I can wash your sheets. There’s a new set in the linen closet.”
Jordyn and I had sex two more times on Saturday before she had to go home. Mom and Dad knew what was going on but didn’t say anything. I had to tell Jordyn she needed to be quieter half a dozen times as she neared and then crested the peaks of her orgasms. Thankfully, Mom and Dad made themselves scarce, which was appreciated, so I didn’t have the idea that they might be watching or listening to us in the back of my mind.
Leah, however, was on cloud nine because she got a front row seat for each time Jordyn and I fucked. It really drove Leah crazy when Jordyn started talking about what my dick felt like while it was inside her. She’d whimper and moan at those descriptions, and I was pretty sure Jordyn was getting off on telling my sister all about it. I wasn’t immune to those effects either, my mind drifting to what it would be like if they’d traded places and I was fucking Leah while Jordyn fingered herself only inches away.
When Jordyn and I were ready, Leah would find the perfect position to watch with the best possible view of the action. She played with her smooth slit furiously, while Jordyn and I went at it. I don’t know if Jordyn saw it or not, but it was plainly obvious that Leah desperately wanted to take a more active role, but we’d already pushed the limits that first time in my bed.
That night, after a late dinner, Mom and Dad announced that they were going to soak in the tub for a bit and wanted us to join them. The look on my and Leah’s faces at the announcement must have been hilarious because both of our parents burst out laughing as they headed out onto the back deck.
“What do you think they want to talk about?” Leah whispered, her eyes flicking from me to the door and back to me again in rapid succession.
“I don’t know,” I replied. “Maybe just what happened today. You know, with Jordyn.”
“God, I hope so.” Leah looked worried. “You don’t think...” Leah but hip lip nervously. “ ... they know, do you?”
“No way.” I shook my head emphatically. “They would have said something if they did, right?”
“Yeah, you’re right.” Leah sighed.
“Maybe it’s about the meeting on Tuesday?” I suggested.
“Let’s just go find out,” Leah suggested. “We might be getting all worked up for no reason.”
“Mom and Dad wouldn’t do that, though.”
“Hell yes, they would.” Leah nodded. “Come on, let’s go.”
The two of us marched outside to see Mom and Dad already soaking in the water, sitting right next to each other in the far corner.
“Come on out, the water’s great,” Mom suggested, and Dad just smiled, his arms spread out on the ledge of the tub.
“Why are you guys acting all weird?” Leah asked, pausing short of the tub, like she was debating turning around and going back inside.
“Weird?” Mom made a mock surprised face. “We aren’t being weird.”
“See, that’s what I’m talking about.” Leah put her hands on her hips, cocking them to the side. “They’re being weird.”
“No, we’re not.” Dad grinned. “Come on in and talk with us a bit.”
Leah and I glanced at each other, neither of us saying a word. I shrugged, and Leah sighed. We could have whole conversations without saying a thing, which drove our parents crazy. If they were going to be weird, then we would be even weirder! I know, it’s stupid, but we’re kids, we’re stupid most of the time.
The two of us climbed into the water, Mom and Dad smiling strangely at us the whole time. We took spots on the opposite side from our parents. We stayed close together, not as close as we would if no one were around, yet closer than we normally would, because Mom and Dad were doing the same thing.
“You want to know what’s weird?” Mom said. “You being in the room when your brother is having sex with Jordyn.”
“What’s weird about that?” Leah fired right back, stepping blindly and willingly into the trap Mom was setting.
Mom gave her a curious look, and I just groaned inwardly, knowing this was not going to end well.
Leah wasn’t done, however.
“Jordyn is my best girlfriend, and she wanted me there,” Leah said, like it was obvious and that there was nothing weird about it. “Lucas, he’s my best, best friend. We’ve been together since birth.”
“A fact we both know quite well.” Mom snickered, and Dad nodded.
“Then you know how close Lucas and I have always been,” Leah replied, grabbing my hand and holding it in hers in clear view of our parents. “Growing up in a family like ours, privacy wasn’t really needed, and frankly, it wasn’t wanted either. Or else you guys wouldn’t have been swinging with Mr. and Mrs. Griffin out in the open in this very hot tub.”
I had to admit, Leah was laying a very sound foundation to her argument, one that would be difficult to refute.
“We know you two are extremely close,” Dad said, his eyes soft as he looked at us. “Like your mom told Lucas, it’s something both of us are jealous of.”
“Lucas told me about that,” Leah said, turning to look at me, and I smiled.
“It’s true,” Dad continued. “I’m not close with any of my family, and neither is your mom. So, for you to have that, it’s great.”
“Yeah.” I nodded, smiling even wider now. “It is pretty awesome. I can’t imagine what it would be like if we were more like Danny and Jez.”
“Those two are like cats and dogs the way they fight.” Mom groaned dramatically, agreeing with my statement.
“We do have one very important question,” Dad said, looking at Mom, who nodded and then turned to us.
“It’s one thing to be close, and we know how close you are,” Mom started explaining. “I’m sure you thought the basement was the perfect little hideout for you two, and Danny, but I’m sorry to report, it’s not.”
“Wha...” My jaw dropped.
“Ohmigod!” Leah’s eyes widened.
“Mhmm, that’s right.” Mom smiled. That was good, at least neither of our parents was trying to strangle us. “We’ve known for years what you three have been doing. Sneaking around, exploring...”
“But—” Leah started to say something, but Mom lifted a hand and stopped her.
“Let me be very clear,” Mom paused, looking at the two of us, making sure she had our full and undivided attention. “We are not upset that you two have experimented together. It’s still a bit strange, but you two have always had such a unique bond that we didn’t question it, as long as no one was getting hurt. What we are concerned about is if it’s more than that.”
