Beach Week - Pt. 04

The next part in Matty's visit to the beach with his sister and cousins. A note: This story series contains themes of incest, specifically sexual activity between cousins, uncles, and the like... in case that's not your thing. This story also has the girls getting into the action; so there are some lesbian sex scenes.

All sexual activity is consensual and takes place between characters over the age of 18.

________________

We ate dinner as a family again out on the patio, and just as we were finishing up a few rain drops started to fall.

"Finished up just in time." My Aunt remarked as we hurried to clear the table.

While my sister, cousins, and I did the dishes, my Aunt and Uncle announced that we were on our own for the night, as they were headed over to their friends' house nearby for board games.

"Unless you kids want to join?" My Aunt offered just before they left the house.

"No thanks, Mom." My cousin Jessica said. "We'll probably play a game of our own."

At hearing her say this, I felt myself tense up with anxiety a little bit at the thought of what might lay ahead. Did my sister tell her about our conversation on the beach earlier, and the admission that I made? Was whatever was happening with my cousin and I going to be exposed out in the open?

But also, I found myself a little excited too. I'd always been so up tight about sexual stuff, especially when it came to admitting what Jason and I had been up to the past couple days. My sister seemed to be outwardly blossoming with sexual confidence the longer she spent time with our cousin Jessica, and I kind of wanted to give into whatever this was and feel that same freedom. Maybe I was gay, maybe I wasn't, maybe it doesn't even matter. One thing was for sure, all of this fun sexual exploration with my cousin Jason was definitely loosening me up... no pun intended.

Jason grabbed another 12-pack from the garage and the four of us convened in the living room. There was no TV at the beach house -- my Aunt and Uncle had always wanted time spent there to be about family -- so the living room was set up with two couches facing each other on opposite ends of the room with a large coffee table in the center. I sat next to Jason on one of the couches and we each cracked a beer and waited for the girls to finish "changing into something more comfortable."

As soon as they came into the room, I nearly spit out my beer.

"That's what you're wearing?" I heard myself ask aloud.

My sister and Jessica both sat down on the couch across from us, each wearing nothing but a t-shirt and panties. I could easily see the jiggling of my cousin's large tits under her shirt, as well as my sister's hardened nipples poking through hers. When they sat down next to each other, they tucked their legs up underneath their bodies so that I could see that each of them was wearing not just panties, but thongs that exposed Jessica's shapely rump and my sister's tight, round cheeks.

"For now." Jessica quipped as the girls each opened a beer. "So, how does everyone feel about truth or dare, boys versus girls?"

"Uh..." I began to respond hesitantly.

"Sounds good to me." My sister shrugged and sipped her beer.

"Game on." Jason said and then our eyes connected.

"Right." I agreed, trying to hide any of the trepidation I felt as my heart beat heavily in my chest. "Let's do it."

"Great, you guys go first." My sister said. "Truth or dare?"

Jason and I exchanged a glance as if in an attempt to telepathically agree on which we should choose. While either option presented their own risks of embarrassment, I was leaning towards dare.

"Dare." Jason said, as if reading my mind.

"Hmmm." My sister hummed as she tried to think of a dare.

"We dare you..." My cousin Jessica chimed in. "To strip naked."

"Seriously?" I asked after exchanging another glance with Jason.

"Yea, wasting no time getting down to it, huh?" Jason added.

"Seriously." My sister affirmed. "Take it off."

Jason stood up off the couch and took off his shirt. I followed his lead a second later, and together we watched one another as we each dropped our shorts, followed by our underwear until we were both sitting back on the couch, fully naked in front of our cousins.

"Ooo, brother..." Jessica said as she eyed Jason. "I didn't realize how much you were packing. Looks like you're excited too!"

I watched Jason blush a little as he tried to shift so as to hide his semi-erect cock between his legs.

"You, not so much bro." My sister said teasingly as the girls both looked to me and my comparatively smaller cock.

"Whatever." I grunted. "Your turn. Truth or dare?"

Like Jason and I had done, the girls exchanged a pondering glance before Jessica answered for them both.

"Truth." My cousin said.

"Lame!" Jason and I both shouted in unison.

"It's our choice." Jessica said. "And we choose truth."

"Fine." Jason said, then started to think. "What do you think?" He turned to me to catch me staring at his cock tucked between his legs.

"Huh?" I snapped my eyes up to his. "Oh, um..."

I looked over at my sister and cousin in their underwear together, their legs had drifted closer and were now touching. It was then that an idea came to me.

"I've got it." I announced with a grin. "What were you two doing last night when we heard all that moaning?"

"Nice one." Jason said aside to me as we watched the girls glance at each other and burst into embarrassed laughter.

"I don't know what you're talking about." Jessica said coyly.

"Come on." Jason commanded. "Truth means the truth."

"Ugh, fine." Jessica huffed, then looked to my sister as if for permission. "Should I tell them?"

"I guess." My sister shrugged bashfully.

"Well, as you know, it gets really hot in the bedrooms here." My cousin started. "So, we decided to sleep naked together, and as we were laying there in the dark, talking before going to sleep, Michelle's hand kind found its way onto my tits."

"And then Jessica's hand kind of found its way between my legs." My sister explained. "And not long after that, her tongue kind of found its way there too."

"So you ate her out?" Jason asked his sister.

"We took turns." Jessica nodded, then looked again to my sister and the girls burst out giggling.

"Did you cum?" I surprised myself by asking my sister.

"No follow up questions." Jessica said. "You only get one."

"Fine." I sighed "Okay, I guess we're up. Should we do dare again?"

I looked my cousin and he just shrugged and nodded.

"Okay." I turned back to the girls. "Dare."

"I dare you two to make out." My sister said.

"What?" I scoffed, surprised by my sister's idea. "With each other?"

"Don't act like you haven't done it already." Jessica snapped. "We heard you just as well as you heard us last night."

"Actually." Jason chimed in, exchanging an embarrassed glance with me. "We haven't...kissed."

The way my cousin hesitated with embarrassment at the mention of the act of kissing made the hairs on my arms stand up anxiously. We'd had some fun -- two horny guys engaged in a bit of innocent exploration -- but kissing was something entirely different. Right?

Kissing was intimate, like lovers. Kissing was... romantic. I'd marveled with the thrill of excitement at having my cousin's cock in my mouth, but did I really feel romantic towards him? And yet... if I were to be honest with myself... there was that moment in the shower where our lips hovered inches from one another's, as if we might kiss.

"Really?" My sister asked, both the girls looking surprised.

"Really." I confirmed.

"Ooo." Jessica cooed. "This will be interesting then."

I looked from the girls, who were both perched eagerly at the edges of their couch, a captive audience, then to my cousin next to me, our bare knees touching as we turned to face each other.

"Okay." I said, letting out a deep, nervous breath.

"Okay." He mimicked. "So, should we just, like..."

"I guess so, yea." I said, and scooted closer to him.

The way we were sitting, with our legs between us, we each had to lean forward at an awkward angle to bring our faces together. As I approached him, my eyes drifted from my cousin's eyes down to his slightly parted lips, and I flashed back to that moment in the shower. Just after I'd sucked his cock for the second time, and my heart was racing with... I don't know... it must have been desire. But, just as it did there on the couch in front of the girls, it kind of felt like something more.

As we inched closer on the couch in front of the girls, and I caught his breath against my lips, I could feel my nerves fade away as my cock started to throb and harden between my legs. When our lips finally connected, I felt us both inhale sharply, surprising ourselves with this intimate contact.

After pausing like that for a moment, our lips pressed together as our breath swirled around us, I felt my cousin start to part his lips against mine and I followed his lead, accepting his tongue slowly into my mouth. At first touch it felt awkward and foreign, a guy's tongue in my mouth, but as I greeted it and danced with it with my own tongue, I found myself giving into his kiss and attacking him more hungrily.

Within seconds, our faces were pressed together in a passionate rhythm, and I felt him put his arms around my naked torso and pull me closer to him. I gave in to his touch, and leaned further and further over into him, at the same time that he drifted backwards onto the couch, pulling me with him.

Slowly as we kissed, he laid onto his back on the couch and I drifted on top of him. I spread my legs around his hips, straddling him, and I flinched when I felt our two hardened cocks press against one another. He tightened his grip around me, and I delighted in the feeling of his hand drifting down my lower back and onto my smooth ass.

"Oh, wow." I heard my cousin Jessica say.

"Yea, that's hot." My sister added.

Their commentary pulled me from the intense, passionate moment of exploring my cousin's mouth with my own as our naked bodies pressed against one another. After a final kiss, our lips parted with a pucker and I found myself looking down into his eyes. We both let out little laughs of embarrassment.

"Bravo." Jessica said as we both turned to see the girls staring at us, enthralled.

I pulled myself off of Jason, sitting back on the couch as he rose back up to sit up next to me.

"Looks like that got you excited Matty." My sister said with a smile, and I followed her eyes down to my crotch, where I could see my stiffness standing at full mast between my thighs.

"Whatever." I said in a huff, reaching for one of the throw pillows to hug over my exposed sexual organ. "It's your turn."

"Yea." Jason said, as he sat up next to me and mimicked me by using a pillow to try to cover himself. "You going to be lame again, or are you ready to really play the game for real?"

The girls exchanged a look, two pairs of narrowed eyes and slightly upturned smirks, as if silently communicating some naughty idea. Then they turned to us again as if ready for anything.

"Okay." My sister said. "Dare."

"We dare you," Jason said immediately, as if he'd been waiting for this moment. "To suck each other's tits."

"Ha!" I heard myself exclaim as I watched the dare settle over the girls. While Jessica responded with a 'so what' shrug, my sister's face turned a shade of red as she looked to my cousin.

"What?" Jessica whispered to my sister. "Not like we haven't done that already. Here, you go first."

My cousin and I both froze on the couch, sitting upright, our knees pressed against one another's as we each shoved a square, plaid pillow against our throbbing manhoods as we watched my cousin Jessica reach for the lower hem of her baggy t-shirt and pull it off over her head in one swoop.

"Damn." My cousin Jason whispered over to me when we got our first look of Jessica's large, natural tits as they jiggled and swung with a bit of heft and sag as she scooched over closer to my sister on the couch. Each of her large breasts was punctuated with a large, almost saucer-sized dark pink areola, centered with a thick nub of flesh.

It was obvious to everyone in the room that my sister was nervous, so Jessica took my sister by the wrists and guided each of her hands to her large fleshy tits. The two girls looked each other in the eye as Michelle began to grip and massage Jessica's breasts. When Michelle's eyes drifted up to Jessica's, the latter gave the slightest nod of encouragement, and that was all my sister needed.

I felt my hand drift down to my cousin's lap, grasping his thigh as if to stabilize myself against the shock of watching my own twin sister -- who I'd always understood to be a bit conservative, if not prude, when it came to sexuality -- lean forward and bring her face to my cousin's hefty left tit, cupping it around the nipple, and running the tip of her tongue wetly around the circumference of the large areola.

In response, Jason placed his hand on mine and gave me a squeeze as we sat glued to the scene in front of us. As he gripped my hand, he pulled it slightly towards the inside of his thigh, and I could feel the flesh of his balls at my fingertips.

"Mmmmm" Jessica closed her eyes and moaned softly as my sister flicked her nipple with her tongue and then sank her nub into her mouth to suckle it.

Jessica tilted her head back in delight as he gently cradled my sister's head in her hands. My sister sucked and popped off Jessica's left tit as she massaged her right with her hand, then after a few moments, shifted between the two.

"Fuck that feels good." Jessica said in a breathless whisper.

As Jason and I watched my sister bring Jessica's pulse and body temperature up, her hips gently writhing against the couch in pleasure, my found myself start to massage the inside of Jason's thigh with my hand. As I did so, I felt him spread his legs and loosen his hold on his covering pillow enough for me to slip my hand between his legs and find his cock solid between them.

Wrapping my hand around its hot girth, I slowly stroked him as he watched his sister bite her lip against the pleasure of having her impressive tits tended to. In response, he slid his hand over to my lap and likewise took my rock-hard cock into his large grip, squeezing it gently and sending shocks of shivering ecstasy through me.

It was then that Jessica turned her head to look over at us as we stroked each other to the site of them. She flashed Jason and I a devilish smile, then reached down around my sister's torso to take up her t-shirt and pull it up off her body.

In response, my sister let go of our cousin's tits and sat up, extending her arms straight up over he head to let Jessica lift the shirt up off of her. I watched my sister's lithe, smooth body -- which wasn't all that different from mine -- appear from the waistband of her panties, up to her slim stomach, and finally to her small but perky tits with their petite round nipples.

"Check it out." Jessica said to her, nodding her head in our direction and cupping my sister's perky little tits as they both turned to see Jason and I making no attempt to hide the fact that we were now actively stroking each others' cocks.

"Enjoying the show, boys?" My sister smirked, mainly to me, then leaned back so as to entice my cousin Jessica with her lithe body.

Jessica took the bait willingly, and leaned forward to place one long, wet kiss on my sister's lips. My sister tilted her head back and closed her eyes with a look of bliss on her face as Jessica kissed down her neck, her collarbone, and finally to her small mounds, where she gripped one firmly and guided it's puffy pink cap into her mouth.

"Mmm, yes." Michelle gasped as she gripped Jessica's hair and pressed her firmly against her tits.

"That's hot, huh?" I heard Jason say as I stroked his solid column of meat.

"Mmhmm." I said in a moan as he squeezed and caressed my own.

After several moments of Jessica lovingly attack my sister tits, I noticed that Michelle's legs had drifted apart and Jessica's hand was slowly sliding up in the inside of her thigh. I watched, wide-eyed, as she got closer and closer to the lace-covered mound at the center, then used her finger to slide the narrow slip of thong aside, exposing my sister's tight, smooth vulva and pink flowery pussy lips.

Pausing from her nipples just long enough to wet her finger with her tongue, Jessica slid her fingertip between my sister's already glistening lips and massaged around her beaded clit.

"Holy shit." I whispered as my sister began to gyrate her hips against the exploring penetration of Jessica as she fingered and caressed her pussy.

"Truth or dare, brother?" I almost didn't hear my sister's voice speak out in a moan as all my attention was glued to Jessica's hand working my sister's pussy. "Matty?"

"Huh?" I snapped up to her face to find her watching me, a look of naughty pleasure in her eyes.

"Truth or dare?" She repeated, the skin of her cheeks and neck a flushed red.

"Uh..." I hesitated, exchanging a glance with Jason, whose cock I still had my hand wrapped around. "Dare."

"Put him in your mouth." Michelle commanded, nodding over towards Jason's lap.

I swallowed hard searching my sister's eyes for something... I don't know what... the courage to do what she was telling me to do in front of her and our cousin Jessica. I'd had Jason's cock between my lips twice, sure, but that was between us. Private. A secret... or so I made myself believe.

I nodded once, not only accepting the dare but eager to fulfill it, then turned towards my cousin Jason next to me. Before I could do anything else, he removed his hand from my crotch and used it to grip the side of my face as he leaned in and kissed me again, his tongue quickly forcing its way between my lips. We kissed hotly and wetly for a moment, then I let him use his hand to guide my face downwards, towards his lap as he threw away the pillow and laid back in his seat.

I used my hand around his cock to aim his head at my lips as I opened wide and slowly ran my tongue around his red, throbbing helmet.

"Oooooh." He cooed sharply the second my tongue touched his flesh.

I smiled inwardly to myself -- hearing my cousin enjoy the feeling of me pleasure him was something I was very quickly becoming addicted to. I slid my tongue around his head and frenulum several times, letting my saliva drip down in streams around his cock, where I collected it in my grip and used it to lube his long shaft. Only when his entire manhood was glistening with my spit, did I suction my lips around his tip and slowly begin to slide down on him, sinking him down my tongue and into my throat.

"Oh fuck!" I heard my sister gasp out, although I wasn't sure if it was in response to the sight of her twin brother sucking our cousin's cock or the stimulation of Jessica massaging her pussy.

As I bobbed up and down on Jason's shaft, I shivered against the feeling of his hand trailing from my head, down my spine to my lower back, then finally to my ass where he took a firm, meaty grip of my cheek. As he clutched my flesh possessively, I felt the tips of his finger settle into my crack and I silently begged them to go further.

"Truth or dare, ladies." I heard Jason say above me, and I drifted my eyes from the base of my cousin's cock to the girls across from us.

My sister was still sitting back on her arms while my cousin Jessica sensuously kissed her neck while massaging one of her petite tits with one hand and rubbing her muff with the other.

"Dare." Jessica stopped kissing my sister's skin just long enough to respond.

"Go down on each other." Jason responded immediately.

I slipped his cock from my mouth and looked up at his face. He smiled back down on me, and placed a hand gently on the side of my face as if to guide me back to his cock.
