Dad and Dave (MMmf, inc, cons)

Written by silentkiller

After my mother died in 1992, my family moved to California. It was my dad, my sister Katie, and me, all starting completely over in a new state. I was 13 at the time, Katie was 9, and if I have the math right, Dad was 35.
Dad got a new job and was out of the house a lot. Within a few months he had a new buddy, Dave, who came over to the house a lot and often spent the night on the couch. Some nights I would get up and find that Dave wasn't on the couch anymore. I'd run into him in the hall or the kitchen and ask him where he had been, and he'd say he'd gotten up early and gone for a walk. Dave was only about 20 years old and a college student that Dad had met at work.
I finally caught Dave and Dad at their business. There was a tremendous thunderstorm one summer night that brought my sister crying into my room. The storm was terrifying her. I took her hand and went to Dad's bedroom, opening the door without knocking. Dad was lying on his back, arms behind his head, legs spread, totally naked. Dave was lying between Dad's legs, sucking on Dad's erect penis. The sheets were kicked down to the foot of the bed. Both men looked at me and Katie, and we stared back.
I knew what they were doing. I had done it with other kids at my school in our old hometown. I was fond of doing it with Nick, my best friend in 5th grade. Every time we spent the night we would start by playing Truth or Dare, which quickly descended into outright cocksucking. We had even discovered the magic number, 69, on our own. Nick and I loved to suck each other's cocks, though we were too young for orgasms, and we were never caught.
I broke the silence first: "Dad, Katie is afraid of the storm."
"Don't you ever knock?" blurted Dave, still lying between my Dad's legs and holding his now semi-erect penis.
"Come here, Katie," said Dad. Katie jumped onto the bed and buried her head in Dad's chest. Dad stroked her hair while continuing to look at me.
I climbed on the bed too. Dave turned away to sit on the edge of the bed with his back to us.
"It's very hot in here," Dad started to explain. "You know I sleep without my clothes ... Dave was just in here, uh, giving me a massage."
I nodded, confused by the lie. I knew Dave was sucking Dad's dick, and I knew how good it felt. Why was Dad going through this charade?
Katie climbed up all the way onto Dad's torso and hugged him tightly. Her nightshirt had ridden up around her waist, and her little ass was clearly visible. She had basically mounted Dad. I could see his cock twitching, returning to its erect state.
Dave glanced back and noticed too. He looked at me and his eyes were full of confusion, then he seemed to make some kind of decision. He winked and grinned, then got back up on the bed and laid next to Dad.
"Dave, I think you ought to go back to the couch ..."
"Come on Frank, I'm scared of lightning too." Dave turned his head and winked at me again so Dad couldn't see.
"Yeah, me too, Dad." I picked up on the game, though I still wasn't sure of the rules.
"OK, OK," said Dad. "What the hell, it's California. Everybody please try to go to sleep now."
Fortunately Dad's bed was enormous and easily fit all four of us. Katie curled up on Dad's right side at the edge of the bed. Dave was on Dad's left side, and I was next to Dave on the other edge of the bed. I turned off the light and pulled the sheet over all of us.
"Dave, let Brett sleep in the middle," my dad said.
"Sure, Frank. Here, Brett, crawl over me and sleep next to your dad."
I obeyed. As I reached over Dave, my hand brushed his erection. It excited me to touch it. I finished crawling over Dave's body and managed to bump his scrotum with my foot.
"Oww!" grunted Dave. "Christ, my nuts!"
"Shhh," said Dad. "Katie's asleep. Suffer quietly, will ya?"
With that, we all lay there in silence.
Dave turned away from me to lay on his side at the edge of the bed. I turned towards Dad and put my arm across his belly. Dad stayed on his back. Katie's arm was thrown across his chest.
It seemed like hours passed by, but I'm sure it was just a few minutes. Dave was asleep and so was Katie. Dad was awake. I was struggling to sleep.
I shifted and my hand brushed over Dad's pubic hair. My fingertip brushed against his still-erect cock. That was it for Dad -- he took my hand off his chest and told me to roll over. So I turned over and laid against Dave's back, spoon fashion.
Again, time passed. I have no way of knowing how long. Then I put my arm over Dave's torso and rested my hand on his abdomen. No reaction from the sleeping Dave. I eased my hand down and took hold of his penis. It was not erect ... but mine was. This was so thrilling to me. I was holding an adult's penis in my hand. Not just accidentally touching it, or looking at it, but holding the whole soft toy right in my palm.
I rubbed it in the same way that I used to rub Nick's penis. Within moments, it was erect. Dave shifted in his sleep. Now my erect penis was nestled in between Dave's buttocks while I firmly held his hard cock in my right hand. Suddenly, Dave's hand went down to cover mine. He patted my wrist lightly, then held my hand and moved it up and down his shaft. He wanted me to jack him off. I was more than happy to oblige.
Dave also eased his hips back a bit to press against my hard dick. I pushed forward slightly in return. This slight, silent, erotic movement continued in the dark for some time. I could hear Dad's sighs of sleep and Katie's light, cute snore. I couldn't hear Dave's breathing at all, but I could sense and feel the slight lifting and dropping of his torso as he took sharp, quick breaths.
Dave reached around to his back and felt my dick. I thought I was in heaven. His big fingers played lightly over my small erection. He stroked and pulled at my nuts. His fingertips ran slowly over my hairless pubic region. Then he seized the shaft and pulled it to his hole. Dave opened his legs to make it easier, then placed the head of my cock against his asshole. His hand released my dick and went back to my buttocks, where he gently pushed as if to urge me to thrust inside of him.
I had stopped jacking him off when he started this new game. I held his hips with my hands as best as I could and popped my little dick into his ass. Dave gasped and I let out a small moan. All four and a half inches of my dick were now inside Dave's hot ass. My balls were pressed into his crack. Dave flexed his sphincter muscle and I grunted with enjoyment.
Slowly, quietly, I started to fuck him. Back and forth. My dick popped out several times but I was able to ease it back in with no trouble. I squeezed and pulled at his dick while I fucked him. It seemed like an eternity of hot sex in the dark, but in reality it was just a few minutes before I ejaculated in his ass. This set his cock off like a water hose, and he thoroughly soiled the bed, the floor and the wall beside the bed with hot jets of sperm. As the spurts slowed to a trickle, I helped myself to his semen, bringing wet fingers from his crotch to my mouth, over and over again.
When we were both finished, I put my arm around Dave and squeezed him tightly. Dave held my arm and squeezed back, pushing his slick buttocks against my slimy crotch area. In that way, we fell asleep.

The next morning we all woke up with piss-hards. I woke up first with my arm still around Dave. I carefully disengaged myself and looked around. Katie and Dad were caught up in a similar embrace. Dad's morning erection was nestled snugly into the small of Katie's back. Dave's penis was rock hard and throbbing in time with his steady breathing. My own penis was standing straight up, poking into my abdomen. I laid back down next to Dave, slid my erection between his buttocks again, and reached around to play with his piss-hard. This woke him up pretty quickly and he turned around to face me.
"Knock that off," he whispered very quietly while stroking my penis, "your dad might wake up."
"So what? I'll just say you were giving me a massage," I said.
"Very funny. Seriously, we can't do this." With that, Dave got up and went into the adjoining bathroom. I heard his piss hitting the toilet water.
Katie sat up and looked at me. "What time is it?" she asked.
I glanced at the clock. "Seven thirty. Let's go get dressed."
"What's wrong with your thing? And Daddy's thing?"
"They're always like this in the morning. Come on, let's get dressed."
That answer seemed to satisfy her. We went to our rooms and got ready for school.

That afternoon, Katie and I came home to find Dave cooking dinner and wearing only an apron. I stared at the smooth, nearly hairless ass that I had fucked just the night before. Dave turned around and gave me the same wink he'd given me last night. Katie didn't notice any of this and went to her room.
"I've just put the ravioli on to boil," Dave said. "Why don't you come with me?"
I followed Dave to Dad's bedroom. He didn't take off his apron. We both sat down on the bed.
"So, Brett. Did you like what we did last night?"
"Yeah. Are we going to do it again?"
Dave laughed. "Yeah, if you want to. But we can't tell your Dad."
I shrugged. "OK."
"You ever done this stuff before?"
"Yeah, with my friend Nick." I described my sexual encounters with Nick.
"That's pretty hot," said Dave, pulling the apron up to his waist to reveal his erection. "You hard?"
"Yeah," I said.
"Let me see."
I pushed down my underwear and shorts, then held my T-shirt up to my chest. My boner stuck out, pink and proud, from my hairless torso.
"You want to do what you and Nick did?"
"Sure."
"Take off your clothes."
Dave untied his apron and threw it on the floor, then laid back on the bed. I shucked my clothes and climbed up there with him.
"Get on top of me and turn around," Dave whispered. I obeyed and found myself facing his beautiful hard cock.
"Lower your hips ..." Dave's voice was soft and distant. I looked down between my legs and lowered my hips so that the head of my hard dick touched Dave's lips. Dave moaned, opened his mouth, and pushed his head up to take the entire length of my shaft in. I closed my eyes and moaned in reply. I waited a few seconds to get used to the amazing, wonderful, heavenly feeling of Dave's experienced mouth on my dick, then I started paying attention to his tool.
It was about six or seven inches long with short, wavy hairs around the shaft and scrotum. It was straight and smooth with a single thick vein running from head to root. I licked it all over, then sucked it into my mouth, as much as I could. Dave grunted and groaned with each flick of my tongue and movement of my lips.
"You're such a good cocksucker," Dave said at one point while my cock stood poised over his sweet mouth. I was running my hands all over his hairy legs, while his hands were very busy fondling and exploring my buttocks. He tried to work a finger inside but I wouldn't let him -- at that point I was not interested in being penetrated that way. Dave backed off and kept stroking my buttocks and torso while he sucked me.
This time he came first and he had the decency to warn me. He gasped, "I'm cumming, Brett," and I had just enough time to take my mouth off the head of his dick before the first blast shot out. The hot splash hit my neck and dripped down to Dave's stomach. I managed to direct the remaining spurts into my open mouth. I savored the sweet globs and sour fluids before swallowing, and licked up the remaining semen that had drooled out of Dave's cock head.
Dave pushed me off of him and cleaned himself while I watched. "Can you cum in my mouth?" he asked. "I'll try," I responded. Dave had me lay on my back while he finished me off. In no time I was bucking my hips and spurting into Dave's willing mouth -- just a few pathetic drops of boy cum, but enough to satisfy Dave. He moved up the bed and kissed me firmly on the mouth.
"That was lovely, Brett," he said thoughtfully while staring into my eyes and stroking my sticky body. "Oh, we can never get caught, you know. Your Dad will kill me."
"I know," I said. "He would have yelled at me if he caught me and Nick."
"Hypocritical, isn't he?" laughed Dave.
I knew what the word meant. "Yeah."
"Well, he won't be home until late tonight, so it's just you and me."
"And Katie."
"Yeah, and Katie. That reminds me, I need to go finish dinner."
Dave stood up and put his apron back on, then reconsidered, removing it again. He put on some of Dad's sweat pants and a T-shirt, then re-tied the apron around his waist. "Get dressed," he said, winking at me, "and find out what your sister is up to."
I got dressed and checked on Katie. She was in her room reading her latest book, a pastime to which we were both wholly devoted. We were the only kids we knew who actually enjoyed reading and always made a killing on those "pay you to read books" summer programs.
Satisfied that Katie was occupied, I went back down to the kitchen. Dave was stirring, sprinkling, boiling and toiling. He had three pots going at once. Smelled like Italian.
"So tell me more about you and Nick," he said. "Did you ever get caught?"
"Nope," I answered. "Well, almost, once. We were fooling around at night in his backyard and his parents came out to use the hot tub. They didn't see us, but we watched them skinny dip and other stuff."
Dave laughed. "What kind of other stuff?"
"Sex stuff."
"That's pretty funny. So you and Nick sneaked back inside?"
"Yeah."
"How did you two get started?"
"We started by playing Truth or Dare and it just went on from there."
Dave glanced at me from the stove and winked again. "Come on, be more specific."
I spun around on the kitchen stool. "Well, we played Truth or Dare, and he dared me to show him my dick and I did. Then I dared him to take off his underwear and he did. Then I took off my underwear, and I dared him to touch me, then we dared to suck each other, and that was it."
"Hm. Interesting." Dave put lids on the ravioli and sauce. "I wonder why Nick wanted to see your dick."
I shrugged. I hadn't thought about it too much.
"Dinner will be ready in about half an hour," Dave said. "Wash up and tell your sister."
I did.
Later, after dinner, Dave and I were sitting on the couch and Katie was on the floor reading.
"Got any homework?" Dave asked. I shook my head. "Wanna watch a movie?" I nodded.
Dave got up and went through our movie collection until he had picked one that I hadn't seen in a while: Top Gun. He put it in and turned on the TV.
About thirty seconds into the opening credits, Katie stood up. "That's too loud ... I'm going to read in my room."
"OK, sweetie," said Dave. Katie went upstairs.
Within half an hour, Dave and I were kissing on the couch and feeling each other's erections through our pants. "God, this is naughty," muttered David as he opened my shorts and stroked my boner. "Let's get undressed."
We quickly shucked our clothes and I kneeled between Dave's legs to suck him. I only had his penis in my mouth for a few minutes when we heard Katie come downstairs. I managed to leap onto the couch and cover my boner with a pillow. Dave crossed his legs and pretended to watch the movie, but made no attempt to hide his hardness.
Wearing nothing but a nightgown, Katie came into the room and assessed the situation. "What are you guys doing?" she asked, still holding her book.
"Nothing, sweetie. What did you need?"
Katie paused to stare at Dave's hard cock. "When is Daddy coming home?"
"Soon, Katie."
We all looked at each other for a few seconds.
"Come here and sit on my lap, Katie," said Dave. I slowly turned and stared at him. Was he nuts?
To my surprise, Katie obeyed. She crawled right up into Dave's lap and straddled him. I could see the tip of Dave's erection poking out from under Katie's ass.
"Turn around, Katie," Dave murmured. She did. Dave hiked up her nightgown to her waist. Now Katie's tiny vagina was pressed down onto Dave's hardness. Dave leaned back and pulled Katie back with him so that her back was pressed against his chest. One of her hands dropped down and fiddled with Dave's dick.
"You can play with it, Katie," Dave said. She did, running her fingers around the head and sometimes pulling it up to press against her labia. I watched, totally blown away.
"Is this what you guys were doing?" asked Katie.
"Yeah," said Dave. "Right, Brett?"
I nodded. "Dad will be home soon."
Dave closed his eyes and sighed as Katie pressed his hard penis against her little hairless pussy. Then he suddenly grabbed her waist, picked her up and moved her off of his waist. "That's right, Dad will be home soon, so you guys need to get to bed. This game that we played tonight? It's a secret game for now, but I'll tell your Dad about it so he can play with us, OK?"
Katie nodded. I knew that Dad would be angry at all of us if he knew, so I figured this was just a ploy to keep Katie quiet. "I won't tell, Dave," I said.
"Me neither," agreed Katie.
"OK. Bedtime," said Dave, standing up and clapping his hands. "Let's go."
I grabbed my clothes and followed Katie upstairs to our bathrooms.
"Do you like that game?" Katie asked as we brushed our teeth.
"Yes, do you?"
"Yeah."
A few minutes of tooth-brushing sounds. Then she said:
"Have you played it with him before?"
"Not really," I replied.
"Oh. I have."
I turned to stare at her. "Really?"
"Yeah."
"What do you do?"
"I just rub his thing on my pee place." She spit out her toothpaste and rinsed off her toothbrush.
I spit my toothpaste into the sink. "You like that?"
"Yeah," she shrugged. "He does too."
"I know," I said, rinsing off my toothbrush.
"So you guys do that?"
I wiped my face with a towel and leaned against the sink. "Yeah, sometimes."
"Do you like it?"
I shrugged. "Yeah."
Katie looked at me for a second more. Then she said, "Good night," and skipped past me to her bedroom.
I stared at myself in the mirror. What was Dave up to? My 9 year old sister playing with his cock? They'd done it before? What the heck was going on?
I went to bed and tried to go to sleep, but my mind was occupied with these new crazy thoughts about Dave and Katie. I heard my Dad come home and talk to Dave. They were up for a while talking. I could easily hear them as they went past my bedroom to Dad's bedroom and closed the door. Since I couldn't sleep, I decided to listen in on Dave and Dad's nighttime activities.
With my ear pressed to Dad's bedroom door, I could easily hear the rhythmic grunts and moans of two men fucking. The door was closed all the way and I knew that if I even turned the knob, it would squeak and I'd be busted. So I tried to figure out a way to watch without getting in trouble.
I remembered a time when I had sleepwalked into Dad's room and tried to pee on his nightstand because I thought it was the toilet. Dad had gently tucked my dick back in my pajamas and carried me to the real bathroom, took my penis out and held it while I peed, then tucked it away and put me back to bed. Even though that was a couple of years before this, I thought it might work again.
I opened the door and stumbled into the room with my eyes half open. Despite the darkness, I could see my Dad behind Dave, fucking Dave's ass. They both looked at me. I heard my Dad say, "Holy shit, Brett, get out of here!" I almost lost my nerve but I stayed in my role and undid my pajamas. I stood next to his nightstand and held my penis in my hands.
"Did you hear me, Brett, I said get out!" Dad snarled. I ignored him.
"I think he's asleep," whispered Dave.
"Oh goddammit, he's going to piss," said Dad.
Just then I realized that I really did have to pee pretty badly, and a bit of urine leaked out of my dick. "Oh shit," said Dad, "grab him!" Dad rolled off the bed on the other side and Dave moved over to me. He grabbed my waist right as I started to really let go. The stream shot out and sprayed his naked leg, but Dave seemed more irritated than interested.
"You got him?" asked Dad. "Take him to the bathroom, for Christ's sake."
Dave took my hand and yanked me down the hall to the bathroom. He pulled down my pants and pointed my dick at the toilet. "Pee here, Brett," he whispered. At the same time with his other hand he was wiping my pee off his leg with a towel. I pretended to wake up.
"Dave?" I whispered. "What's going on?"
"You sleepwalked into your dad's room and tried to pee on us," he whispered back, chuckling a bit. "Now I'm helping you finish in the right place."
"Feels good," I said, leaning back against him. Of course, he was still nude. I felt his cock rising into my back. My own penis was getting hard, cutting off the flow of my urine.
"You're so naughty," Dave breathed into my ear. I turned my head to face him and we kissed, a long, passionate kiss with tongues twirling, lips mashing. His hand began to stroke my erection. I turned to face him and we embraced, stroking each other's dicks, still kissing.
"Do you wanna?" Dave managed to say, breaking free from our kiss. I nodded and sat down on the toilet. He knelt in front of me and started sucking my penis. I held his head with my hands.
Just then my dad came in the bathroom. Dave looked up and I shut my eyes. Dad hissed, "What the fuck are you doing, David?"
David was quick on his feet, or in this case, on his knees. "He's asleep, Frank. He can't piss with a boner and I wanted to make it go down."
Silence from my dad. I dared not open my eyes.
"Frank, come here," whispered Dave.
I heard my dad move across the bathroom floor.
"Frank, he's asleep, he has no idea what's going on," Dave argued in a soft, seductive voice. "Come here."
I sensed my Dad kneeling next to Dave.
"Go ahead, Frank, you've always wanted to."
An eternal moment of hesitation ... then I felt a soft kiss on the head of my prick. I cracked my eyes & looked down just as my father took my entire dick into his mouth.
Despite myself, I gasped and put my hands on his shoulders. I looked at Dave, who gave me a big, slow, sexy wink. Then I closed my eyes again, to keep up the subterfuge of sleep.
Dad's warm mouth moved slowly and wetly over my shaft, back and forth, over and over. It was a tremendous thrill. I could hear Dave's breathing, and the light, whispery sound of his hand rubbing Dad's smooth back. I could hear the soft buzz of the fluorescent light. I heard a car pass outside. But most of all, I heard the juicy, sensual sounds of Dad's mouth servicing my penis.
This didn't really last long - within seconds I was leaking my young cum into Dad's mouth. He swallowed and sucked me dry, then I heard him kissing Dave. I made a snorting sound like I was waking up, and Dad hurriedly left the bathroom. Dave was grinning a huge grin at me when I opened my eyes. "That was amazing," he whispered. "Go to bed, tiger."
I smiled and leaned over to kiss Dave. It was a deep, passionate kiss, lasting for several minutes. Dave broke it off and said, "Seriously, Brett, go to bed. OK?"
I went to bed without a complaint.

The next day was Saturday and Dave wanted to have a picnic by the pool. The four of us made lunch together in the kitchen. Katie was wearing a one piece swimsuit with a T-shirt over it. Dave wore tiny Daisy Duke-style cutoff jeans. Dad and I wore T-shirts and bathing suits. We all joked around and had fun while making lunch but I would catch Dad looking at me and my body in a weird way every now and then.
Out at the pool, the two adults basically sat in the pool chairs and ate while me and Katie splashed around for a while. Dave jumped in and horsed around with us, throwing me and Katie around and so on. Suddenly I was hungry, so I got out and headed for the cooler full of drinks and sandwiches.
I was surprised to see Dad nude on his pool chair. "Getting some sun, Dad?" I asked.
He smiled, but I couldn't see his eyes behind his sunglasses. "Well, nobody can see us in our backyard, eh? Besides, it's nothing we haven't seen before."
I looked away when he said that. Was he making some kind of reference to what happened the night before? It didn't seem like it. I glanced over at his penis: it was limp, resting like a lazy snake on his right thigh.
While eating my sandwich I continued to steal glances at my naked Dad. God, he was beautiful, for a fortysomething family man who didn't get much regular exercise. Dave and Katie got out of the pool and Dave ushered Katie over to the food. Then he noticed Dad's nudity. "Oh, hey, let me join the nudist camp," said Dave. He shucked his Daisy Dukes and plopped down in the pool chair next to Dad. I looked at his cock: also limp, also gorgeous. I thought about all the times that I had had his penis in my mouth and I instantly got a boner.
"Going to join us?" asked Dave, smiling at me. When I didn't immediately answer, he winked at me in that weird, seductive way he has.
"He needs some work on his tan lines," laughed Dad. "His ass is as pale as a fish's belly."
I stood up and shrugged, then pulled off my swimsuit to reveal my completely erect dick, then I laid back down on my pool chair on the other side of Dad.
Dad and Dave looked at me. Dad suddenly grinned and said, "Good grief, Brett, you've certainly grown," he chuckled. Dave just smiled and looked away.
"Katie, it's time for you to get tan all over," I said. Katie looked up from her peanut butter & jelly sandwich, a bit of peanut butter smeared across her cheek. "Wow, OK," she said. She stood up and stripped bare, then sat back down to finish her sandwich. She sat cross-legged so that we could all clearly see her beautiful, bare, petite little pussy.
I stared for a few moments, then looked over at Dad and Dave. Both of their cocks were rock fucking hard. Dave was actually fondling himself a bit.
Katie finished her sandwich and said, "When can I get back in the water?"
"About an hour," sighed Dad. "Just rest for a while, honey."
And so the four of us were sitting in pool chairs, totally naked. The three males had big fat erections. I started playing with mine, timidly at first, then openly jerking it. Dave was doing the same. Dad looked at both of us and grinned. "Guess I'll join the circle," he said, and started pulling on his own stiff prick.
Katie ignored us for a while and then asked if she could sit in somebody's lap. Dad just stared at her but Dave said sure, come on over. Katie straddled Dave's lap and laid back against his chest just as I had seen her do earlier. I held my breath and waited for the next inevitable, line-crossing action. So was Dad, I think.
Dave's erection was sticking up between Katie's legs right between her pussy lips. Katie reached down and took hold of Dave's dick and started her rubbing motions.
"My God, David," stammered my Dad.
Silence for many minutes as Katie absently fiddled with Dave's hard dick and rubbed her privates against the shaft and head. Dad and I were really beating off now. The sun shone down hard on all of us. Sweat was pooling in all the crevices of my body. The air smelled of perspiration and chlorine. Birds chirped in the trees. I could hear everybody breathing and the sound of flesh rubbing against flesh.
"Katie, baby, that feels great, hold on," said Dave, closing his eyes and putting his head back. I knew what was about to happen. As Dave's hands clenched the armrests of his pool chair, his cock discharged a long, glistening string of hot sperm across the bottom of his chair and onto the hot pavement by the pool. "Jesus fucking Christ," hissed my dad as Dave's cock continued spurting and then drooling cum everywhere.
Katie stood up. "I gotta pee pee," she said. Dave managed to say, "Katie, honey, do it here and wash this stuff off of me." She glanced behind her to see if he was serious, then squatted a bit and let loose. A hot, loud stream of urine hissed out of Katie's glistening pussy and rinsed the sperm away from Dave's dick, thighs and chair.
"Katie, come here," grunted my dad.
"But I'm not finished!" she said, looking up from her obscene shower to look at her father.
"Katie, come here now," Dad said again. My sister stopped pissing and stepped over to Dad's chair. "Straddle me," urged Dad, "and do that to me." Katie obeyed. Another golden stream hissed out of her little pussy to soak Dad's hairy crotch. Dad immediately started cumming - the little globs splattered all over Katie's thighs and pussy. I stood up and moved next to Dad.
"Dad, I'm cumming," I said.
Dad turned his head and opened his mouth. My buttocks clenched and I closed my eyes, really yanking at my cock, when I felt the first spurt race up the shaft of my penis. I looked down right after the sperm hit Dad in the chin and redirected my cock so that I would cum in his mouth. He leaned over some more so that his lips were touching my cock, and he swallowed the rest of my ejaculation. Katie finished pissing and moved away from Dad.
When I finished, I leaned over and kissed Dad on the mouth. Our tongues collided and tangled, and I could taste my own cum on my Dad's tongue. It was the sexiest moment in all of my 14 years. Dave started applauding next to us and Katie giggled.
We broke our kiss. Dad looked at me, then stood up and gave me a huge bear hug. I could feel (and smell) Katie's piss all over his body. He put me down and looked at us all.
"Let's get cleaned up," Dad finally said. We jumped in the pool and rinsed off, horsed around, and generally acted like nothing at all had just happened. After an hour of this activity, Dad got out and went inside. Katie got out too. Dave and I stayed in the pool for a while. 
"Can you believe it?" asked Dave, swimming up behind me and goosing me. I jumped and turned around.
"I know ... I don't know what to think," I said.
"Let's go see what your Dad and Katie are up to."
Inside, Katie was in her room, in her bed, still nude, but reading a  book. Dad was in the shower. Dave and I joined him.
"Hey guys," said Dad, smiling.
We both hugged him. The hug turned into a group grope. Soon we were all hard as rocks again. After the shower we went directly to Dad's bedroom and continued our groping on the bed.
Dave and I took turns sucking Dad's dick, then Dave asked Dad to fuck him in the ass. Dad got behind Dave and slid his cock in easily, just like I had always been able to do. I got in front of Dave and put my cock in his mouth. Together, Dad and I fucked Dave from both ends and filled him with our sperm. In the middle of it, Dave shot his own wad all over the bedsheets without even touching himself. It was fucking incredible. The three of us cuddled on the bed, trading kisses and still stroking & groping each others' bodies.
"How did all of this happen?" asked Dad.
"How long will it go on?" replied Dave.
"I hope it never ends," I said, squeezing both of their dicks.
And it never did.
