Just so you know, everyone in this story is over the age of eighteen.

I noticed the three of us were all smiles as we watched the parents board the cabin cruiser, to start the three-hour journey back to the city.

After the two of them had kissed the twins and said goodbye; my mom gratefully smiling up at me, brushed a kiss to my cheek, and whispered, “Thank you so much for taking care of them, Joey.”

I kind of winced, feeling a little guilty, considering ‘just how’ I was taking care of them, by pretty much pounding their sweet little pussies every chance I got.

Once we’d waved them off at the dock, the three of us looked pretty happy about being on our own again. Especially knowing that we could finally get back to the sexy fun and games we’d been enjoying, before the folks showed up, forcing us to stop.

Now that the coast was clear, and we could do pretty much anything we wanted, the way the two of them were smiling down at my package, I wondered what they had planned for me.

But knowing how kinky the two of them were, I had a pretty strong feeling it was going to be something really hot, that my twitchy little friend was obviously going to enjoy.

Once we got back in the cottage, before we got sidetracked, I pointed over to the kitchen area, and suggested, “How about we have some lunch?”

Considering how hard we’d been going at it, I figured we needed something to eat, just keep ourselves functioning.

They both nodded, looking slightly disappointed, probably because we’d be eating with our clothes on. Before the folks had showed up, we’d been walking around in our birthday suits. Which of course, I thoroughly enjoyed, getting to watch the two of them strolling around completely naked, showing off their little shaved pussies, and big luscious tits.

Talk about a dream come true.

As soon as the twins were done with their lunch, they smiled at each other, and announced that they were going for a swim.

I just nodded, thinking that once I’d finished cleaning up the kitchen, I’d join them. But I almost choked on the last bite of my sandwich, as I stared at them wide-eyed, watching them slowly begin to peel off their shorts, doing a sexy little bump and grind as they teasingly pushed them down, till I could just see their slits peeking out at me.

Then holy fuck, I could feel my eyes flare when they tossed aside their little crop tops, and unclipped their bras, letting their big, beautiful breasts bounce free.

Licking my lips, eager for a taste, I couldn’t believe how hard their nipples were, standing proudly erect.

The two of them, coyly smiling into my eyes, slipped off their tiny, black lace panties, and tossed them aside.

Waving their arms over their heads, they did a little shimmy, that got their tits jiggling and their asses swaying, while also making my frustrated dick grow thick as fuck in my shorts.

I could feel my heart pounding as they grinned at me, teasingly jiggling their titties, daring me to make the next move. While my poor throbbing cock was pulsing like a second heart-beat, pounding through my veins, sure that after that little strip show, he had to be harder than fucking granite.

Kendra nodded at me, smirking. “Okay, big guy, your turn.”

More than happy to oblige, I stood up and took my time easing my fly down, getting off on the sounds of the two of them whimpering, obviously eager for a peek at my rock-hard friend.

When I finally let my shorts drop to the floor, I almost laughed at the way their eyes popped when my cock bounced up and sprang free and smacked me right in the stomach.

I was glad now that I had decided to go commando, knowing that as soon as the folks were gone, we’d be back right back at it.

“Oh wow, Joey, you’re as thick as my wrist,” Cassidy cooed, hungrily eyeing my erection, as I jacked it in my hand, making them anxiously clench their thighs.

“You still want to go swimming?” I asked, trying to keep a straight face, since I knew floating around in the lake, wasn’t exactly what they had in mind right now. At least from the way they were both twisting their nipples and licking their lips, as they eyed my cock flying through my fist.

“Oh, fuck,” Kendra murmured, watching me squeeze out a bead of pre-cum, smearing all over the angry red tip, till I had it nice and slick, and ready to push his way inside them.

“I thought you’d never ask,” I said, nodding at the couch. “Both of you lean over the back of the couch, and spread your legs open wide.”

I had to fight not to laugh at how quickly they scampered over and did as they were told, legs open wide, with their asses in the air.

But fuck me, what a sight, as my gaze locked on the apex of their thighs; eyeing their tight pink pussies already dripping, and just itching to be fucked.

Coming up behind them, I slid a finger into each of their hot little holes, and I rolled my eyes, as I felt them clenching their inner muscles, trying to draw in my probing fingers.

“Play with your tits girls, tug at those big, hard nipples,” I told them, as I dropped to my knees.

Just the feel of sliding my tongue over her hot, slick folds had me groaning, as I pushed my tongue into Cassidy, while working a second finger inside her. They were just so tight, I could feel my cock pulsing like crazy, aching to push its way inside them, to give them each a nice hard ride.

“Ooh, that feels sooo good,” Cassidy cried out, getting off on me licking her up and down while finger-fucking her into what looked like the start of a pretty intense orgasm.

Still working my fingers into her hard and fast, hoping to push her over the edge, I leaned over and pushed my tongue into her sister. I loved how quickly she started shaking and shivering when I suckled her clit between my lips, flicking it with my tongue.

“Oh, wow I’m coming so hard!” Cassidy cried out, her sister already moaning and desperately crying out, right beside her.

I was so fucking ready to pound them, I could feel my dick dripping onto my thighs. Still, I took the time to nurse them through their orgasms, until finally they both collapsed, every inch of them shaking and shivering, after coming insanely hard.

Turning their heads, they let out the most elated sighs, smiling at each other. I guess enjoying the fact that the two of them were getting off together. While I was pretty stoked, that I was the one making it happen.

“Now, let’s get a leg up on the couch,” I said, sliding a hand under their thighs, raising the right leg on one and the left on the other, and resting them on the back of the couch, so I had them opened up nice and wide, with their pussies glistening with their juices.

“Please Joey,” Cassidy nearly begged, watching me get to my feet. I flashed her a devious smile, pumping my slicked-up friend in my hand, that was dripping like crazy, now that he knew where I was planning to bury him.

“I’m gonna try and fuck you both,” I told them, getting in behind Cassidy. Clutching my dick at the base, I clenched my jaw and I pushed in, till we were both shuddering at the feel of my fat cockhead popping into Cassidy’s tight little opening.

Her breasts heaving, she dug her hands into the couch, and hung on for dear life, muttering, “Oh wow, it feels like you’re splitting me in two, Joey. You’ve got me stuffed so tight.”

Bending my knees, I carefully eased my way in, and began pumping into her a little deeper with every thrust. Until we had a nice steady rhythm going, with her thrusting back, and softly moaning as she obviously got over the initial shock of being packed to the max, and was now getting off on the feeling of being fucked.

“Damn, you feel good,” I told her as I relished the feeling sliding into her nice and deep, with her clenching around me like a warm, snug sheathe.

Feeling Cassidy starting to tremble, I grabbed hold of myself and pulled out, and got in behind Kendra. Dropping a kiss on her shoulder I told her, “Don’t worry, baby girl, it’s your turn now.”

Knowing that Cassidy was still riding an orgasmic wave, from the way she was quaking, I kept working my fingers in and out of her, while I was getting off on the incredible sensation of driving my cock just as deep into her sister’s snug little puss as she could take it.

It wasn’t long and they both were crying out at once, “Oh, wow, I’m coming!”

“Who wants it?” I asked, feeling my legs trembling and my pulse racing, knowing I was right on the edge. Growling, I kept thrusting into her, deep and hard, drilling her like a mad man. I could feel my balls kept growing tight, as I got closer and closer to losing my load.

“Please, Joey, fill me up,” Kendra pleaded.

I chuckled. “Well, since you asked so nicely.”

Laser focused on the erotic sight of my juiced-up cock flying in and out of Kendra, bending my knees, I just kept pumping and pumping and pumping, till I felt the most incredible wave of relief wash over me. Grunting like a beast, almost wanting to pound my chest, I let go and erupted like a volcano, shooting off deep inside her spasming cunt.

I just couldn’t stop shuddering, as my cock kept spewing, giving up what felt like a massive load.

Grabbing my dick around the base, my legs trembling, and my heart pounding, I quickly pulled out, took a step to the right and pushed my way into Cassidy’s quivering little pussy.

I smiled, watching her stand on her tiptoes mewling like crazy, while I gritted my teeth and kept right on pumping, till I knew that I’d filled her up with the last of my seed.

“Wow!” They both gasped, on a shaky breath, happily smiling at me over their shoulder. Of course, I was smiling right back, having never experienced anything even half as wild as that.

Then I looked down and started chuckling, thrilled to see a nice thick trail of white hot cum, sliding out of their well-fucked pussies, dripping down their thighs, and making two pretty impressive puddles on the floor.
