Chapter 1: A Diverse Family
Incest Sex Story: Chapter 1: A Diverse Family - If there's one thing I learned growing up it was if you're fifteen, horny, and "available" you tend to have a lot of boyfriends. Years later it appears my cousin Tammy has learned the same "lesson". Even better, her current boyfriend didn't mind having me join in as well, even though I was six years older than him.

While extended family isn’t the largest compared to some people I know, what we lack in quantity I think we make up in diversity. On my mom’s side there’s just her divorced sister Linda and her daughter Kristen. My mom’s dad died back when I was only nine years old so I don’t have many memories of him. For as long as I can remember, my Aunt Linda and Kristen have practically lived at our house and I consider Kristen more of a sister than a cousin.
On my dad’s side, it gets a lot more complicated as he has two brothers, one older and one younger, and a lot more cousins. Uncle Paul, the oldest of the brothers, lives closer but we don’t have nearly as much to do with their family for whatever reason. As a result, other than the holidays and weddings, I rarely see my older cousins Ginny and Laura. They are both older than me and married so other than an unexpected invitation to a bachelorette party a few years ago, things are pretty formal when we get together.
In sharp contrast, we are much more involved with my dad’s younger brother, Uncle Jim, and his family, even though they live on the north side of town. Probably because Uncle Jim and my dad are closer in age they seem to hang around a lot more with each other and thus by default, so do their families. All three of my cousins there are younger than me with Rick being oldest, having just turned nineteen. Kate is sixteen while Tammy turned fifteen back in June.
Without going into too many details (I’ve explained those previously in my dairy), I’ve been involved sexually with my parents for the past six years. If you’re not familiar with incest and our relationships, read my diary so I don’t bore everyone else too much. With regards to my cousin Tammy, as she is the one this particular diary entry is centered around, we first experimented a couple of years ago. It wasn’t anything too drastic, just an older cousin helping her to learn more about her growing needs and how to take care of them.
Unknown to Tammy, about a week after we started fooling around I let her dad fuck me for the first time. Again, it’s a long story but suffice to say I’d been teasing him for years and my dad thought it might help out his chances with getting Tammy someday if his brother was fucking me already. One thing seemed to lead to another and two days later, unknown this time to both Tammy and her dad at the time, I started having sex with her older brother Rick who had just turned seventeen at the time. For the rest of the summer and fall, that was pretty much the status quo until Tammy caught me and Rick doing it at their house one day. Actually, that paved the way for her first BJ (using her brother’s dick) but certainly not the last. Tammy quickly earned a reputation for being the most fervent, of not the best, cocksucker in her middle school. For reasons I never quite understood, she firmly refused to yield her virginity, especially to her brother who was dying to fuck her.
My own dad had been dreaming of what he’d like to do with his youngest niece for years. I think it started when she wore a really skimpy bikini over to our house and joined him in the hot tub looking like the cutest little thing to come out of sixth grade. This led to yet another day that I’ll only describe briefly and that was when my dad actually DID get her virginity, although she was fourteen which was sort of cool since that was the age I had my first time (although not with my dad).
The next day, Tammy and I were out on our boat with both of our dad’s for what turned into our first “father-daughter swap”. It was really erotic for me as not only did I watch Tammy’s dad fuck her for the first time, but both fathers agreed to share and thus got to fuck the other’s daughter. It turned out to be the last as well as although my dad has fucked Tammy a few times since then, those have been few and far between and it’s been months since his last taste of her cute little pussy.
Having finally graduated from college back in May, I was finally home for good. Once I was home and back in touch with what was going on, it didn’t take long for me to find out that my youngest cousin was well on her way to eclipsing every “record” her slutty (and proud of it) cousins had set in school years ago. Kristen was especially excited about Tammy’s “growth”, especially since her partners were all younger boys from school which just happens to be Kristen’s primary interest when it came to guys.
