The three of us eventually made our way to the basement family room where my dad turned on some golfing show on the TV while my mom read her latest romance novel. As for me, I curled up on the couch and fell back asleep again until I was awakened by the doorbell.

“Kelly, why don’t you go let them in?” my mom asked me.

Instantly awake and fully alert, I nodded and ran upstairs to open the front door where I saw Tammy and Rick standing. My heart skipped a beat as I realized they’d actually made it! For some reason all week there had been this nagging doubt in the back of my mind that something was going to happen where they wouldn’t make it but such doubts were now laid to rest.

“Hey guys, come on in!” I greeted them.

Tammy was dressed in a cute pair of denim cutoffs and a tight pink plain cami. Her little boobs were clearly outlined underneath and her ass was half hanging out from the tight shorts that barely concealed anything. I wondered if she had left the house that way or changed on the way over. I couldn’t imagine her mother letting her wear anything close to it. Rick was also wearing shorts but his came down past his knees. He had a dark blue tank top on as well but it was baggy and hung on him like it was several sizes too big. It was interesting to see how similar types of clothing could be worn so differently by a boy and a girl.

“Hi Kelly,” Tammy said softly as she entered the house and went by me as I held open the door. It was almost like she was being shy but then shy girls don’t show up at their relative’s home dressed like a slut with the intention of fucking their uncle!

“Hey Kelly,” my cousin Rick greeted me, grabbing my ass under my t-shirt. Well, HE certainly wasn’t being shy about anything as his hand squeezed my bare ass.

“Ahhhhhh, someone forgot her panties again I see,” he teased me.

I swatted his hand away playfully. He looked good, hot actually. For a moment I felt like taking him to my room and letting him do me instead of my mom. Better judgment kept me from doing so but it WAS tempting.

Turning to Tammy, I reached down and gave her a hug. Even though she was almost fifteen, she was still barely five feet tall and some people might have mistaken her for being closer to twelve or thirteen. It seemed to run in my family. My cousin Kristen was always complaining that people thought she was still in high school instead of having already finished two years of college. Although I wasn’t as youthful looking, my body development certainly lagged behind most girls. Anyone who says girls mature earlier than boys should have seen me stuffing a bra when I was seventeen!

“Mmmmmmm, I’m so glad you made it today,” I told her, feeling her hug me in return.

Tammy looked at Rick with a frown and the way his eyes narrowed I had a feeling there was something going on between the two of them that I didn’t want to know about. Having never had a brother or sister, I lacked experience in such sibling interactions but even so, something told me that it hadn’t been as easy as Rick just inviting his sister to come along.

Hoping to avoid getting off the on the wrong foot, I quickly led Tammy and Rick downstairs to where my parents were still planted in their chairs. Based on the discussions I’d had with my mom earlier in the week, it surprised me to find them exactly where I’d left them instead of upstairs in the bedrooms.

“Hi, how you guys doing?” my dad greeted them, breaking what was starting to be an awkward silence.

It wasn’t like this was a normal thing for us to do. Typically, whenever we had sex it was usually the outcome of something else that led up to it rather than making it a stated intention from the outset. Of course Rick’s “yard work” visits were pretty obvious that was something unique between him and my mom. I couldn’t think of a single time that my cousin Kristen had come over JUST to be fucked by my dad. Now with her mom ... well that was a different story but things were different there. As for me, I had never gone over to my cousin’s house just for sex and the few times my uncle had fucked me had been as much a surprise to me as anything else.

“Hi Uncle John, Aunt Mary,” Rick replied. Tammy just nodded along with him, not having said a word yet since she’d arrived.

At this moment I wasn’t sure WHAT to do. It was completely ad lib from this point forward as I’d never been in this sort of predicament before. It all started with the intent of getting my dad an opportunity to fuck his little niece but now it seemed to have morphed into something entirely different - exactly what, I still wasn’t sure at this point.

“Why don’t you come over here and sit on my lap, Tammy,” my dad offered, waving her over like a Santa Claus at the mall. The only difference was Santa didn’t sport a hard-on under his suit - or at least not so anybody noticed.

Once again she looked at her brother but it was so fast that if I hadn’t been looking for it I would have missed it. Whatever it was she put on a smile and walked over to my dad’s chair and climbed on board. My dad was wearing a pair of shorts and a t-shirt and probably little else if I knew him. Normally he wore underwear but when he was pretty sure he would be getting some he left them off to make things easier. Tammy sat sideways in his lap, her thin, coltish legs draped over the arm of the chair, leaning back against her uncle’s strong arm that he easily wrapped around her tiny body.

With Tammy in place I took my usual spot on the couch, feeling pretty useless and not just a little bit out of place. For a moment I considered leaving the room and letting them get on with it without me acting as a spectator but my own horniness vetoed the idea. I hadn’t seen my dad fuck Tammy since that fateful weekend last summer when he took her virginity and I would be dang if I was going to miss it now!

That left Rick standing alone in the middle of the room. Rick was almost nineteen and he did what most any nineteen year-old horny boy would do in this situation - he walked over to my mom’s chair and took a position to one side of her and promptly started to undo his pants.

“Whoa young man, you in a hurry or something?” my mom exclaimed, pretending to be surprised at her nephew’s boldness. With Rick, it would have been more surprising had he done anything else. It wasn’t like he needed to seduce my mom or work for it - he KNEW what he was there for and he KNEW what my mom wanted him to do to her so why bother playing around pretending otherwise?

“Here, get on the other side then,” she instructed him. I realized she was positioning him on the other side so that my dad could see what was going on from his chair. My dad must have appreciated it as seeing his wife suck his nephew’s hard cock would have to be a lot better than looking at the boy’s bare ass.

Rick shuffled around, trying to hold up his pants as he went around her chair and leaned up against the arm. He let go of his shorts and they dropped to the floor, leaving him standing in his white Hanes underwear. The tight jockey shorts were having a hard time constraining the erection hiding beneath them and his cock head was starting to peek out over the elastic waist band.

My mom reached for some hand lotion from the lamp stand next to her chair and shook some out from the bottle into the palm of her hand. Reaching out, she took Rick’s hard dick in her hand and started to stroke him, spreading the creamy lotion all over his stiff shaft.

Meanwhile, my dad had wasted no time in fondling Tammy through her thing cami, rubbing his large hands over her small boobs, covering them easily with the large palm of his hand. She still hadn’t said a word but from the way she was biting her lower lips and running her tongue across her lips, she certainly seemed to be enjoying it. As my mom started stroking her brother’s dick, my dad lifted her cami up and over her boobs, exposing their simple beauty for all of us to see.

“Looks like someone’s ready for you Mary,” my dad called over to her. My mom just grinned and kept stroking Rick’s hard dick slowly, working her hand expertly up and down as well as around it in various combinations.

Having said that, my dad lowered his head and let Tammy lean back more so he could lick her nipples and take her little boobs in his mouth. Her sensitive nipples were large when you compared them to the size of her budding breasts and they hardened quickly as my dad tugged on them gently with his teeth and teased them with his tongue.

Meanwhile, I just sat there and watched, so mesmerized by the sights and sounds in front of me that I wasn’t even thinking about touching myself. It was the first time in my life I’d seen such a sight and I didn’t want to miss a moment. Seeing a brother and sister having sex with a husband and wife made me think how things might have been in our family had my mom been able to have more kids. The only thing that would have been hotter would have been if it had been their own mom and dad instead of their aunt and uncle.

“Show me your tits Aunt Mary,” Rick asked my mom.

Typical boy. Stroking his dick wasn’t enough - he wanted more! My mom shrugged and lifted her top with her free hand, exposing her large boobs for his viewing pleasure. My mom was a solid 36D, maybe closer to a 38D, and her boobs were still pretty firm and not nearly as saggy yet as many women her age. She loved showing them off and Rick certainly seemed to enjoy them!

My dad’s hand had made its way between my cousin’s legs as he continued to suck on her little boobs. At first he just rubbed her crotch through her shorts. As short as they were, they were so tight there was no way he could slip his finger under the hem or anything. She didn’t protest in the least and if anything, lifted her one leg higher and out more to make it easier for him to get to her. Her legs were still skinny but they had started showing more promise in recent months and she was already well on her way to her summer tan.

Nobody seemed to be paying attention to me and personally, I was hoping that it would stay that way. Rick seemed to be enthralled as he stared at his aunt while she fondled his stiff dick and teased him by putting her mouth up just close enough to touch her tongue to his dick but only doing it briefly before drawing back again.

As for my dad, he was interested in only one thing at the moment - Tammy’s boobs and crotch while she was just leaned back against him, her eyes closed and her mouth partially open as she seemed to enjoy being groped by her uncle.

My dad started fumbling with Tammy’s shorts, trying to work them off her but they were much too tight for that. Finally, after letting him fuss with them for a few minutes, she smiled at him and used both hands as she lifted her hips up and pushed them down and off her tight little ass. My dad took over from there, slipping them easily down her thin legs and over and off her bare feet. As he held them up briefly before tossing them to the side, I marveled at how small they were. Sheesh, I knew girls with dolls that had have bigger clothes than Tammy!

With her shorts now off, Tammy pulled her cami up and over her head, leaving her stark naked on my dad’s lap. God she looked SO cute - and HOT. Anyone looking at her might think that she was just some innocent little girl, no different than the hundreds of girls you might see at any church or school. What gave her away was her comfort in being nude with my dad, her unabashed nakedness that she was more than ready to flaunt and even “use” when necessary. A closer look revealed the slutty nature that resided in her, the lust and taste for being naughty that far exceeded her years.

Tammy twisted on my dad’s lap such that she was now laying against his left shoulder with her ass against his stomach and her feet resting on his upper thighs. Her knees were bent which helped raise her crotch, making it more accessible for her grateful uncle. My dad had his left arm under her, cradling her like a small child with his arm wrapped around her and holding onto her little boob. His right arm was extended down her thin body, his hand planted between her spread legs. I heard her gasp ever so slightly as his finger worked his way into her tiny pussy and started stroking in and out of her. He wetted his finger in her and then drew it out to apply it to the outer areas of her pussy.

By this time my mom had her mouth firmly planted on Rick’s demanding cock. I had to give her credit for holding out as long as she had before switching from using her hand to her mouth. Normally I only bothered with hand jobs when the circumstances limited my options - such as in a restaurant, church, etc. I mean, why hassle using your hand if you had the opportunity to suck it? She wasn’t giving it her all yet, though, just bobbing her head slowly on him, letting his imagination do most of the work.

“OH!” I heard Tammy cry out, taking my attention away from my mom and Rick.

My dad had apparently pushed a second finger into her and was now finger fucking her with both of them. It obviously hadn’t been a cry of pain or surprise but more one of pleasure as she had her eyes closed and was rocking her hips a little to be in rhythm with his finger strokes.

Rick was enjoying my mom’s mouth on him judging by the groans and grimaces on his face. My mom was using her tongue heavily on him now, running it around the heads and up and down the shaft while her hand cradled his hairy balls. She had taught me early on the advantages of using your tongue in addition to straight sucking. Knowing Rick, I figured he would be cumming soon so I kept my attention pretty much fixed on the two of them with Tammy and my dad just out of the corner of my eye.

“Oh wow Aunt Mary, that feels so good!” he cried out as my mom was now into some serious cock sucking.

No more toying with him or teasing him, she was intent on getting his first load of the day, or at least his first load since arriving. What my mom wanted, she usually got.

I couldn’t help but look away for a moment as I noticed Tammy repositioning herself. She was like a little monkey on his lap, scrambling all over him. She turned completely around to face him and put one foot on each of the arm rests. My dad grabbed her by her narrow waist and pulled her towards him as he leaned forward until his face was buried in her little crotch.

From my angle all I could see was her cute ass and the back of his head but I had little doubt what he was doing. For just a moment I felt a little funny as my dad rarely ate my pussy. Usually it was me doing the oral and then him directing the rest. It wasn’t that I didn’t WANT him to lick my pussy, it just wasn’t something I pushed for I guess.

Tammy kept her balance with my dad holding her waist and her hands on his head. His hands were so large on her he could almost touch his fingers behind her back. I tried to imagine how good she must taste when she was this horny. It wasn’t all that hard to imagine as after all, I HAD been the first person to ever lick her pussy but that was years ago.

Wouldn’t you know it, I looked away for one moment and my cousin started to cum. If he hadn’t moaned so loudly on his first shot I might have missed the entire thing! As it was, he was shooting his cum all over my mom’s breasts, leaving trails of white gooey sperm that stretched across her boobs from one side to the other. As he finished up, she started to rub it around like lotion, covering her boobs with a shiny coating of cum that I would have loved to have been invited to come over and lick off. No such luck, though.

Once he had cum, Rick stroked his dick to keep it hard as my mom dropped the foot rest on her Lazy-Boy, letting her legs dangle down towards the floor. She kept the back leaned backwards and looked up at her nephew. Thank God the dummy was able to take a hint! He returned to the front of her chair and kneeled down on the small rug that was in front of the chair. My mom had her legs spread wide apart and her nightshirt wasn’t nearly long enough to hide the view between them.

“Your turn,” she said to Rick. Just what it was his turn to do she didn’t have to state - it was obvious!

Rick put his hands on my mom’s upper thighs and leaned forward, not hesitating a second before plunging his face into her hairy pussy. Obviously this wasn’t the first time he’d done this to my mom!

Back to my dad again - why wasn’t I taping one or the other so I could watch just one pair now and then catch up on the other later? Anyway, it looked like my dad was getting ready to be more serious. Tammy leaned back and balanced herself on the arm rests while my dad undid his shorts and pulled them down just enough to expose his dick. Of course by now he was hard as the Rock of Gibraltar!

A glance over at Rick and mom showed his face was glued to my mom’s pussy. Who could blame him? I loved the feel of her hairy pussy against my face as I licked her. She kept it trimmed so it wasn’t a wild bush but it was still pretty full.

Tammy stayed facing my dad and simply let her feet drop from the armrests to seat so she was now straddling him. Bending her knees like she was getting ready to jump off, her bottom lowered itself down to where my dad’s hard dick awaited her.

The room was eerily quiet, about as opposite as you would have expected if such a scene was being shot for a porn movie. None of the load moans and cries of a faked sex scene. Instead, the four of them just enjoyed themselves, with perhaps a gasp now and then and maybe a soft main but nothing dramatic. My mom was usually the loud one. Growing up with nothing but an old thin wall between our bedrooms, I could remember many a night lying in bed, listening to my mother moaning and talking dirty to my dad. Maybe it was more for my dad’s benefit all those years?

Of course, no sooner had I noted how quiet it was than my dad broke the silence.

“Oh yeah, that’s it Tammy ... sit on it,” he urged his little niece.

Tammy had her hands between her legs, guiding my dad’s dick to its destination while simultaneously spreading her tight pussy apart for him. She had more of a look of determination on her face than anything and I could understand why. Taking an adult man’s cock in her tiny pussy couldn’t have been an easy task! How my dad had fit himself into her a year ago was still a miracle as far as I was concerned!

“Shit, you’re so damn tight!”

Ignoring him, Tammy raised herself up and started to lower herself down for a second attempt. Obviously her first try hadn’t succeeded but she was stubborn and I knew she wouldn’t give up easily. Sure enough, she dropped down and I could see my dad’s stiff cock actually bend slightly as she pushed down hard on it. Then it was like she just dropped a couple of inches suddenly as his cock penetrated her and slipped inside.
