Chapter 1: Two Brothers and Their Kids

Incest Sex Story: Chapter 1: Two Brothers and Their Kids - Ever since my uncle first had sex with me over a year ago (my how time flies!), one of my dreams was someday he and my dad would do a daughter swap. As for my dad. it would be easy to convince him as he had been dying to have sex with my youngest cousin Tammy for years and yesterday finally got to take her virginity. With each brother now having done their niece, I figured it was only a matter of time before we all got together - I just didn't realize how fast it would happen!

If you’ve been reading my diary then you know incest has been a loving part of my family for a couple of generations. I personally became involved over two years ago, just a few months after I turned sixteen. Given I’d been sexually active for a couple of years by then, it wasn’t like my father introduced me to sex or groomed me or anything like people seem to assume when I discuss this. Such people’s narrow-minded attitudes probably stem from reading those stupid incest stories and web sites on the Internet which are nothing more than male fantasies with no connection to real life. Anyway, for the next several years my incestual relationships were limited to my parents (I’m an only child) and my mom’s sister and her daughter (my aunt was divorced when my cousin was only a few years old).

When I said “my family” at the beginning, I should have said “my mom’s side of the family” to be more precise. My dad’s side of the family was never involved in incest in any way when he was growing up. That’s not to say the boys were prudes by any means! My dad’s younger brother, my Uncle Jim, had sex with my mom back when they were in high school which isn’t all that shocking considering from the way my dad tells it, she did with most of the boys back then. Of course that was all before she married my dad but even if the two of them had continued it would have been adultery rather than incest.

My Uncle Jim always seemed to have his eye on me while I was growing up as did his son, my cousin Rick, who was a few years younger than me but already quite a hunk. I’m sure their minds were filled with all sorts of nasty thoughts but they were men after all so what else would you expect? Because they had been raised within the confines of society’s rules and taboos they never actually DID anything other than look up my skirt or down my blouse, innocent stuff like that. It didn’t help that I got a kick out of teasing them - not because I wanted them for sex but just because I loved to tease.

Just as his brother was turned on me, my dad craved his brother’s youngest daughter, my younger cousin Tammy. Tammy was four years younger than her brother and had just turned fourteen this summer. In the past couple of years as she started to develop, I knew that my dad couldn’t help but get horny whenever she was around. Even so, other than masturbating at the thought of being with her, he never laid a hand on her except for those times when she would tease him by sitting and wiggling on his lap. She always acted so naive and innocent but I always had a suspicion she was well aware of that lump under her butt.

It was over a year ago that I first showed Tammy how to have fun on-line with guys. One thing lead to another and before it was over I’d taught her a lot more, such as how to lick a girl’s pussy. Of course I used mine as a teaching tool! By playing around with Tammy the wall between our families had been breached and it wasn’t long before I got more serious about teasing my Uncle Jim. Then came the time I did it in front of my dad who graciously offered me as a present to his brother - a gift which was quickly accepted.

While my dad lusted for Tammy, my mom had her own thing going with regards to my cousin Rick. Once I broke the ice by letting my uncle fuck me, it was only natural that I should go after Rick. At his age he was an easy target but as it turned out, my mom was the one who took over from there. Having an older woman making herself available to him trumped even sex with me it seemed and although Rick and I got together every now and then, it was my mom who really seemed to turn him on.

For the rest of the year, that was the extent of the relationships. Basically, I was having sex with all three of them - Tammy, Rick and Uncle Jim, but always alone and not together with any combination of them. The biggest secret was that while my Uncle Jim knew his son was doing my mom (and me occasionally), he wasn’t aware of what I’d awakened in his youngest daughter. Of course he knew my dad was fucking me but I’d never seen any sign from him that he was interested in that type of relationship with his own daughters. More importantly, I doubt he knew just how badly my dad wanted to fuck Tammy!

Getting the three of them to have sex with me was a good start but I had bigger ideas. The next “step” in my plan came to fruition during Christmas break. I arranged for Tammy to “accidentally” catch her brother fucking me and her natural curiosity and teen sexuality took over from there. The first thing I did was to teach her how to do a blowjob although it didn’t require much on my part - she proved to be a natural. Even though she liked to suck Rick’s cock, Tammy steadfastly refused to let her brother fuck her. I had to give her a ton of credit for her incredible willpower. She would let him rub his erection against her pussy and even allowed him to cum on her pussy but when it came to penetration the answer was always the same - a solid NO. You can imagine how Tammy’s refusal to let him fuck her was driving Rick nuts at times but he wasn’t complaining TOO much given her skill at blowjobs. As it turned out, Tammy loved sucking cock almost as much as I do which made her quite popular with his friends to say the least.
