Emma's POV
A week had passed since the first time we ventured to the cove, and we'd returned twice since when the parents hadn't been watching us closely. Keegan and I had been sneaking off while everyone was busy, and it wasn't until we'd found ourselves with the house to ourselves that we let loose. We knew all the parents were on the beach, and that Amy, Lucy, and Thomas had gone to town by themselves to do who-knows-what. All we knew was that we could be as loud and rough as we wanted.
"Ohhh, right there," I moaned, bent over against the arm of the couch as Keegan rammed into me from behind, "and keep it coming!"
"Yes... Emma that feels good," he replied breathlessly, with his hands gripping my ass so tightly I thought he was going to tear me apart. "Bounce on my cock, baby..."
I rocked my ass on his, feeling him going faster and faster against me. I always got such a rush fucking somewhere public, and this time was no exception. Knowing anyone who walked close enough to our patio could easily look through the window and see my tits bouncing and mouth agape made my pussy catch fire, and as dog walkers and girls in string bikinis walked past I could feel myself getting wetter and wetter.
"You like that, huh? You like getting fucked on the same couch our parents sit on?"
My mind drifted away from me, as I imagined us all sitting in the lounge playing UNO or whatever game my dad chose, and Thomas or Amy leaning against this spot on the couch which I was dripping on... would they notice it? Smell it? Know what we'd been getting up to? It left me feeling buzzed, and I could feel my wetness getting stronger and stronger...
"Please, more," I gasped as he pulled out. "You can't leave me hanging like this Keegan, I'm so close to cumming..."
He moved across to the armchair in the corner of the room facing the narrow kitchen entrance, sat down, and beckoned me over. My heart beat faster, knowing last time he fucked me like this was in front of his sister. I moved off the couch, in awe of his throbbing member, and turned around shyly to get ready to sit on him. His hands guided me, and as soon as I felt his head slip into my cunt I groaned.
"Are you gonna fuck me rough? Are you gonna make me cum hard, Keegan?"
"Yessss..." He hissed as I sat on him, "Fuck, that feels so good..."
We got into a rhythm punctuated by gasps and moans as we hit each other's sweet spots, and as he started to rub on my clit I swore I heard a door opening.
"Mmmmm," he hummed, "close to coming, you little slut?"
"Ahhh," I gasped nervously, feeling my nipples harden at the thought of somebody potentially hearing. "Yes?"
"I can't hear you," he whispered, rubbing faster as he thrusted harder into me.
"Y-yessss..." At that moment, I felt a wave of pleasure starting to overcome me. "Yes, yes! Ohhh Keegan, I'm gonna cum, I'm gonna uh-" At that moment, a figure appeared in the doorway. But I was too close to cumming, and I could feel my body reacting without me being able to control it. "Fuck! Yes! Ugh!" My cunt contracted and squeezed Keegan's cock as my eyes shut, and I could almost feel someone's gaze going all over me, eyeing me, wanting me...
"Baby, yes, fuck!" Keegan's cock began to pump inside me, and I could feel my body relax. As I opened my eyes, I saw a figure suddenly darting away from the door. Who was it? My mind began to worry, but I calmed as I realised it could be Thomas, Amy, or Lucy. It was probably them, sneaking in for one of the beers our parents had in the fridge, and getting an eyeful of us in the meantime.
Keegan came down from his orgasm, and I slipped off him, aware of his cum dripping down my leg. He 'hmm'ed appreciatively as I turned around, and got up.
"Honey, you have no idea how much you turn me on when you've got my cum going down your leg," he whispered deeply into my ear.
"And you have no idea how I feel when I feel you cumming inside me," I countered, leaning up to him for a kiss. I heard the patio door shut, and Keegan started.
"I'll check that, hold on," he said, walking off completely nude. I laughed a bit, wondering who was there, and followed. The door was closed, and nobody seemed to be there. "Odd."
"Spooky!" I teased, wrapping my arms around him. "I wonder who that could've been!"
"The wind, probably," he said. He turned around, and looked down me. "Anyway, I can think of something a bit more important than worrying about a door."
"Which is...?"
"Getting all this cum off you." He grinned, and I smiled back. "Shower?"

Jax's POV
Well. I can't say I was entirely to blame for forgetting to bring out the beers Renee asked me to bring.
"Jaxie, where's the beer?" she asked as I came back from my trip to the house.
"Umm..."
"Oh Jax," my best friend Trent guffawed. "Take two, buddy?"
"Yeah, probably won't hurt," I said jokingly as I turned around. "Whoops!"
Truth is, when I walked into the kitchen I wasn't expecting to hear the sound of fucking. I opened the door, and heard a voice that sounded suspiciously like my son asking a girl if she was, quote, 'close to cumming, you little slut.' I certainly did not expect to hear Emma's cherubic voice moaning back. My cock was immediately hard, despite my best intentions, and I pulled down my shorts out of pure arousal. Admittedly, this wasn't the first instance where I'd seen Emma in an untoward light. The first time was when she'd bent over to get some meat out of a cooler on her first day here, and I remembered how fresh and wet it looked. I'd felt myself getting hard, and I tried to distract myself by checking out my wife. For all my efforts, it proved useless, as that night I couldn't resist looking at her when she wasn't looking. She was probably a B cup, and in her short skirt and tight top I wanted to do nothing more than tear them off her and feast on her supple legs and cute tits. When everyone went upstairs to bed, I immediately gave my wife our 'horny' look, and that night we fucked roughly. It took all of my willpower not to picture Emma on the bed, but I managed.
The second time was when all our kids went off for a walk on the beach. They came back covered in sand and very giggly, but Emma's swimsuit showed off a perfect little cameltoe on the front (that looked rather damp) and a perfectly cute little ass behind. My eyes lingered there for a bit longer than they should've, and that night I dreamed of her making her swimsuit all wet rubbing on her hand. I woke up with a raging boner, but luckily Renee took care of it for me.
The minute I heard her moaning though, I knew I had to see her. My cock exposed (and rock hard), I walked over slowly to the lounge, and poked my head in.
God. It was hot. Ignoring my son on the couch (whose face was completely obscured by Emma anyways), Emma looked absolutely fuckable. Her mouth was open, her lips were hot and wet, and her whole body looked perfect. Her breasts... I always wanted to be faithful to my wife from the day we married, but I did have a secret penchant for watching porn on my computer when she wasn't home, and Emma's tits looked like the sort I'd have come into a tissue over when I was younger. And her pussy, oh god, was wet and getting pounded. Never mind that the pounder was my son, she looked hot as hell.
"Oh fuck Keegan, I'm gonna cum!" I nearly jumped when she said that, but I realised she'd been quietly moaning before that. Her body twisted, and I took ahold of my cock, giving it a good tug. She started to pant, and then squealed as the hand on her clit sped up. "Fuck! Fuck!" I gritted my teeth, and eyed her up as her legs started spasming and she started fucking my son's cock harder. Her little cunt was dripping, that was for sure, and if she was alone in her room, hands between her legs and leaking cum, I would've fucked her on the spot. God, she looked that hot. I was opening touching myself now, aware that if she opened her eyes she'd see a man more than twice her age stroking himself. The thought turned me on a bit more than what it should've, and as she let out a final squeal I wished it was my cock she was riding.
Keegan then started to show signs of cumming, and as soon as he started talking I darted away from the doorway between the rooms and picked up my trunks. Quickly, for fear of being caught, I clumsily got my suit back on, and then got out of the kitchen, shutting the door behind me. I darted off, and as soon as I realised what I'd done I felt my cock involuntarily throb. I leaned against a nearby tree, and mulled over what I'd just seen. A cute little 18 year old, getting fucked by my son, and cumming all over the couch.
Well, I guess I knew where I was sitting that night.
