Incest Sex Story: Chapter 1: Leading up to Easter - If you were a man in your forties and you had the opportunity to have sex with a sexy sixteen year-old girl, would you turn her down? Of course not. The question then becomes, would it make it even better if she was your brother's youngest daughter?

I’ve written a lot about my feelings regarding incest in gruesome detail in other entries so I won’t belabor the issue again. There IS one key point, however, that is relevant to this situation that needs to be repeated. One of my “guidelines for incest” is that I believe both parents should be involved, preferably the entire family, to avoid potentially explosive situations, not to mention the inherent tension that comes with being forced to keep such a massive secret should either the mother or father not be involved.

So having said that, now I am left to rationalize why I preach this to others but haven’t followed my own guidelines when it comes to my own family. First, it was never my original intention to initiate anything incestual between my cousin Tammy and he dad, my Uncle Jim, or her older brother Rick. As much as I’d like to think otherwise, I’m NOT always totally in control of every situation and things sort of took on a life of their own and got out of hand.

Actually, it all started rather innocently, just a little bit of cousins fooling around in her bedroom one day after we got horny from some naughty chatting on the Internet. Even at thirteen, Tammy had a natural aurora of sensuality about her that made me feel it was appropriate, even though she is six years younger than me.

It might help to remind everyone that back in their teen years, my dad and his youngest brother were quite the hustlers from the way my mom described them to me. Both of them had sex with my mom (as well as her sister) while they were in high school but in the end, my mom married my dad while Uncle Jim married my Aunt Shari shortly afterwards. Being Uncle Jim was her husband’s brother, my mother could have continued on having sex with him without violating her marriage vows, but my Aunt Shari was definitely NOT the type to condone such actions. Frankly, I’ve never really understood why my uncle married her in the first place being she is so prudish. Still, while he may have remained to faithful to his wife (out of fear more than love?) I saw how he looked at me when I was around, especially when I flirted with him a little.

Thus it really didn’t come as a huge surprise to me to learn that when my dad suggested that I might be “available”, any worries about the wrath of his wife fell away and soon he was doing what I think a lot of uncles like to do - fucking his niece. As I mentioned before, technically he wasn’t committing adultery as I was his brother’s daughter and thus a member of his family, but I doubt my Aunt Shari would’ve seen it the same way.

To be honest, while I’d always found it fun to tease him, my uncle isn’t exactly the nicest guy in the world and the only reason I allowed his to fuck me was to please my dad. Even so, at first it wasn’t all that bad. In fact, once he was doing me it seemed only natural for his son to follow in his footsteps and needless to say, Rick was more than willing to go along. Thus in the space of just over a week, I’d taught my youngest cousin about girl-girl sex and had sex with my uncle and his son. Quite a week, to say the least, but then in my experience, it seems that once when things get started they tend to take off rapidly so in retrospect, it really wasn’t that surprising.

One thing that DID catch me a little off-guard was to learn that my mom had her eye on Rick as well. Once I’d broken the ice with Rick (during which she helped things get started but then stayed away once it heated up), it was only a couple of weeks before she took advantage of the Rick being a member of her family. Other than my uncle, Rick was the only guy to have sex with my mom since she married my dad and anything with my uncle was way back when they first got married.

Thus Rick was the first guy she’d been with in over twenty years besides my dad. Being a horny teenage boy with extensive staying power didn’t hurt either! To be sure, my parents are VERY strict about adultery and anyone who knows me understands that they have passed on those principles to me as well. Bottom line, if someone is not a member of your family, then they are off limits once you’re married - no exceptions, not even if the spouse gives “permission”.

For the next few months, things pretty much went along as usual. My mom suddenly seemed to have a lot of odd jobs for Rick to do. Fortunately for everyone, his insane mother was totally clueless about everything. Actually, I doubt she could’ve even imagined such a thing going on between her sister-in-law and her son so it’s not like she suspected anything.

After the first time we played around, Tammy and me didn’t do all that much together. What we did was fun to start but with her mother’s overbearing ways and her older sister’s being a clone of her mother, it wasn’t like we had all that many opportunities anyway. Besides, I got the impression Tammy was more interested in boys.

When I was returned for Christmas Break from college, I had some more fun with Rick and so far as I knew, Tammy had no idea that I was having sex with her brother and dad (although sex with my Uncle was very rare, thankfully). Then a couple of days after Christmas she caught us together and to my surprise, she was interested in learning to suck dick. While it killed Rick that she refused to let him go all the way with her, it did open new doors between the two of them.

As things turned out, I learned she gained quite the reputation for being a cock teaser which helped explain her interest that first time! As much as Rick begged, Tammy refused to give up her virginity to him. I didn’t do anything to try to push her into having sex either. When she was ready, she would do it and nobody should ever push a girl into taking that step until she is ready. Till then, she seemed more than happy polishing her newfound blowjob skills.

It wasn’t until the following summer that anything changed much. It was August and Tammy had just had her fourteenth birthday in late June. Our two families were on a weekend trip to a state park where we boated and just relaxed, something we did periodically. It was there I took the initiative that changed everything, so far as Tammy was concerned at least.

First, realize that I’ve always felt a deep sense of guilt because I didn’t give my virginity to my father. To be fair, when I was fourteen I had no idea whatsoever he was even interested in me that way, but still, things are what they are and I shouldn’t have been so naive and read the signs to recognize what he wanted.

Looking back, it was pretty obvious but I missed it completely. It wasn’t until I was sixteen and had sex with my parents for the first time that my mom confided in me his earlier desires - and disappointment when he learned that a sixteen year-old boy had deflowered his little girl. Everyone keeps telling me that I shouldn’t feel guilty - but I do.

So here I was in our cabin, my hot little fourteen year-old virgin cousin lying next to me, and my parents sound asleep in the next room. It doesn’t take much imagination to figure out my thoughts at the time. Since he didn’t get to have ME when I was fourteen, why not let him be with Tammy? In my mind, it would be sort of like she was acting as a surrogate for me, giving my dad a chance to experience something that he most likely thought he would never be able to do.
