Chapter 6: My Aunt Linda Makes It a Threesome

Incest Sex Story: Chapter 6: My Aunt Linda Makes It a Threesome - Hard to believe but my dad is now on the downward slope to 50! There are a few days each year that are special when it comes to me and my dad - Father's Day, 4th of July, his birthday and Christmas. Of course, it's HOW you make a day special that counts! Note: Reading this over after I wrote it, I may have repeated myself a lot and dwelled on certain topics a bit much. My apologies if that's the case but these things are important to me and are hard to put into words so please bear with me!

“Another one?” was all he asked, looking incredulous. I nodded and he grinned even more.

He had to know it was one of two people - my Aunt Linda or my cousin Tammy. In my heart, I knew he was hoping for Tammy and I wished then that I had found some way to get her involved but she simply wasn’t available. Besides, it would have been more difficult for a girl her age to wander into the office without someone taking notice. Kristen showing up at the same time as me was already pushing the envelope but to have a seventeen year-old slut coming in after us would have certainly raised some interesting questions.

Following the same procedure as before, he went to the door and looked to see who it was. He just shook his head as my Aunt Linda walked in. At least she had remembered to bring a card and a present, hopefully tipping off the staff that was all about his birthday and not something else that their imaginations might be dreaming up.

“Happy birthday John,” she greeted him and then they kissed.

She turned and saw the two of us on the couch. Kristen had turned over and was sitting next to me, her one leg draped over mine and each of us had one hand on the other’s pussy.

“Hmmmmmm, looks like you’re having quite the birthday party, John” she teased him, “I hope you don’t mind if I join in?”

It was then I took notice that she was wearing a long trench such that all you could see were the black boots she was wearing. Without waiting for a response from my dad (it’s not that the answer was in any doubt), she unbuttoned the trench coat and opened it up to reveal that the boots were the ONLY things she was wearing under it! Damn, that must have been so hot for her to drive downtown, park and walk into the office knowing she was totally naked under the coat.

“Wow, is this my birthday or did I die and go to heaven?” my dad said incredulously, looking between her and the two of us on the couch.

We all laughed and Aunt Linda removed the coat, leaving her boots on. Walking over to the couch, she motioned for me and Kristen to spread apart and she took her place between the two of us. I couldn’t remember the last time the three of us had been naked together like this and I’m sure my dad was enjoying the sight as well. Aunt Linda put one hand on each of our legs and rubbed them up and down.

“Well, you two have a head start from the looks of things. John, why don’t you fuck your daughter for while mine gets me ready?”

Like, what man is going to say no to THAT proposition? Kristen didn’t hesitate for a second, quickly hopping off the couch and getting between her mom’s legs, her head disappearing between her thighs faster than you could say “eat me” and started to lick her mom. It made me think for a moment how much she must be missing doing that since her mom had moved in with my dad.

Kristen had been sleeping with her mom since her dad left when she was a little girl so it was only natural that they started having sex when she was at an early age. As for me, I was sixteen before I licked my mother (she was also my first pussy I tasted other than my own). In contrast, I knew Kristen had started with her mom at less than half that age but in was different in her case, more of a natural progression over the years then suddenly having sex with your mom one day after doing nothing more than masturbating together prior to that.

My dad smiled as he saw Kristen eagerly licking her mom’s pussy. Again, what man wouldn’t love the site of a daughter licking her mother’s pussy? Aunt Linda raised her hand and shrugged as if she was saying she had no control over what Kristen was doing - despite the fact it was her idea in the first place. Then he turned to me and the humor was replaced with lust as he started to stroke his dick in his hand as he looked at me with an intensity that was almost frightening. Oh yeah, he was horny and now he going to fuck me and there was absolutely nothing in the world that would stop him.

This time I turned to my side and he slid in behind me as I lifted my top leg up and over him with my bottom leg out straight behind me, exposing my wet pussy to him. Our heads were facing Linda and Kristen such that I could actually hear her lapping up her mother’s increasing wet pussy. It was hard to actually see her tongue on her as my aunt’s pubic hair was pretty bushy and hid her daughter’s face as she pressed it into mother’s pussy. For just a moment I felt a slight pang in my heart as I remembered how it had been when I could do the same with my mother, who also preferred to keep her pussy natural, just trimming it enough to be presentable in her outfits and bikinis.

Any such thoughts were quickly replaced by the wondrous sensation of my dad’s dick entering my needy pussy yet again. He had one hand helping to hold up my leg and the other around my neck such that he could reach my boob as he fucked me.

“Damn John, your dick looks so hot in her pussy,” Aunt Linda remarked, her eyes fixed on where my dad’s dick was now buried completely inside his daughter’s pussy.

Despite my best efforts, I couldn’t help but giggle slightly as his stiff pubic hair tickled my bald pussy when he would start grinding his dick in me, moving his hips in tight circles to twist his dick around inside of me.

“You’re tickling me daddy,” I apologized.

“Well, I would certainly hope I’m doing more than just THAT!” he came back with a chuckle as he started stroking his dick in and out of me.

My dad was starting to pick up speed and it didn’t surprise me given the situation he was in. How many men at his age, or ANY age for that matter, could hold back for long when fucking their daughter while watching his sister-in-law being eaten out by her daughter - the same niece he was just fucking a few minutes earlier?

“Hey, don’t you dare cum in her yet, forgetting about me?” my aunt teased my dad.

With that, she gently pushed Kristen away from her pussy. Kristen pretended to protest but she couldn’t help but grin, looking positively slutty leaning back on her heels with her face coated with her mother’s pussy juices.

Aunt Linda laid back on the couch with one leg up on the top and the other over the edge, her head supported by the arm rest at the other end. She started rubbing her pussy, spreading herself open and pushing her pubic hair to each side to give my dad a good view of her motherly pussy.

“C’mon, it’s my turn!” Aunt Linda said, sounding a little perturbed that my dad was still fucking me.

I looked at him and smiled, then I whispered it was OK and he pulled out of me and moved in between my aunt’s legs, quickly burying himself in her hairy pussy.

As my dad fucked his sister-in-law, his niece and I masturbated again while we watched - her on the floor and me on the couch. About all I could see was my dad’s ass and his cock pushing into my aunt’s hairy pussy between his legs while Kristen was getting a much better view.

Even though my Aunt had been fucking my dad all my life, I didn’t know about it until I started having sex with my dad myself back when I was sixteen. Looking back it made sense considering all the times she would stop by and she and my dad would disappear, supposedly to help with her realty business legal needs. Yeah, she had needs alright, but they weren’t legal! After that, even though I knew they fucked, it was rare that I actually got to see them in the act, typically only at times when the family got together such as our 4th of July annual traditional orgy.

For me to just sit there, masturbating slowly while I watched my dad fuck my favorite aunt, was actually something new for me. Looking at Kristen getting herself off, I wondered if she ever got to watch them when he went to their house for sex. At what age did she first see them doing it? Did she join in? Did she start fucking her uncle even before the times I knew about? There were times I suspected as much. Although technically such questions weren’t off limits, common courtesy kept me from asking. I figured if they wanted me to know they would tell me.
