Chapter 4: My Dad Fucks Tammy in Front of Her Dad

Incest Sex Story: Chapter 4: My Dad Fucks Tammy in Front of Her Dad - 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!

“Well Tammy, are you ready to show your daddy your favorite new way to have fun?” he asked her with a naughty grin, looking back at us to make sure we were paying attention - as if somehow we wouldn’t be!

Tammy looked back at her dad, her finger to her mouth like a little girl unsure what she should say. It was one thing to get caught up in things in the early hours and let my dad fuck her - quite another to do it out in the sun on our boat, especially while her father was watching. Not only was her dad going to watch, he was doing it while he was fucking her cousin as well. It was turning out to be quite a day for a fourteen year-old girl and I hoped she didn’t become overwhelmed by everything. She was a trooper though, and one with an overactive sex drive at that.

“Daddy?” she said softly, “Is it OK with you?”

I felt her dad bounce under me as he laughed, making me tingle a bit as I felt his still erect dick move inside of me. It wasn’t a mean laugh but more one to put himself and her at ease.

“Well, I don’t remember you asking me this morning if your uncle could fuck you,” he chuckled.

She looked confused, almost scared, as if she was afraid he didn’t approve. Her dad quickly tried to put her at ease, “Ahhhhhh, it’s OK baby, show me what you’ve got.”

Tammy looked relieved at first and then she turned to look at my dad. I watched her and it was as if suddenly this innocent little girl change into a sultry temptress. The look on her face was so full of desire and lust as to be almost unbelievable. I understood her completely though. Once I learned how great it was to be fucked, I wanted it more than anything after that and I knew what she wanted - and wanted more than anything in the world right now. Her pussy must have been throbbing so hard as to almost hurt. It had felt a cock once and now it couldn’t wait for another one!

Tammy got up and out of the seat. She looked so small next to my dad! Her head barely came to his chest and she weighed less than half of what he did. When she was sucking her brother it was hard to imagine she was only fourteen but now she looked even younger and so innocent it was almost scary. I was beginning to understand my mom’s concerns about my dad fucking her when she was this young - well, almost. In reality, I couldn’t wait to see that hot little girl impaled by my dad’s hard cock again!

As Tammy reached behind her head to untie her bikini top, I felt the cock in me throbbing as her dad watched his youngest daughter undress. I could only imagine what must have been going through his mind as well at this moment. How did he feel seeing his youngest daughter stripping down like a little child-prostitute, preparing herself to be fucked? Whatever he was thinking it must have been pretty hot as his dick was throbbing hard in me and he was raising and lowering himself just enough to keep in moving constantly in me. Uncle Jim’s cock pushed into me even more as Tammy started to strip. I wondered then if he had ever seen her nude before, at least since she had started to mature into what was obviously going to be beautiful woman someday. Had he sneaked peeks of her, maybe in the bathroom in the shower, and then gone off and masturbated as he dreamed of doing his own daughter?

Tammy dropped the top, openly exposing her budding breasts for the very first time to her father. I felt a rush of hot air on my neck as he took in the sight of his half-naked daughter. She then quickly slipped down her bottoms to her ankles and stepped out of them, straightening up as soon as they were clear. I could see that I was going to have to give her some lessons in stripping but today I don’t think it mattered to either father as they watched her. Everyone’s eyes in the boat were on her now - including mine. Somehow with her suit off, standing there totally nude, she looked even younger than before. Maybe it was the tiny boobs or the light covering of peach fuzz on her pussy. Most likely it was her naive-looking face that led you think maybe she was only eleven or twelve - at most. In any case, at fourteen she definitely was a turn-on for the two men who were almost three times her age!

“Oh ... my ... god,” I heard my uncle whisper to himself behind me, “She’s fuckin’ beautiful.”

Indeed she was. Tammy was practically beaming as she saw the way her father was staring at her in a way she had never seen him look at her before. Not only that, but she was getting this attention while his dick was buried in her cousin’s pussy! It wasn’t like she was deliberately trying to show herself off, but with the sun shining down on her perfectly smooth tanned skin, the slight breeze blowing her hair across her face, she was like a little angel. The fact she was nude made it even better as there nothing hidden any longer from her father. She was totally exposed to him, allowing him to see her as he never had before. I smiled at Tammy, trying to reassure her and boost her confidence. I knew from my own experience that nothing made you feel as confident as having the complete attention of a man, knowing he wanted you and lusted for you with every inch of his body. That was certainly the case for Tammy now - times two! My dad certainly wanted her but there was no doubt from the heavy breathing behind me and the pulsing of the dick in me that her dad wanted her just as badly!

I could see the look in Tammy’s eyes that told me she realized the same thing was happening. She must have been feeling more sexy and hot than she had ever felt in her life at that moment. I could only imagine the thoughts she must be having knowing she was the complete center of attention of two men closest in her life. Heck, even the man who was fucking another girl at the time was paying more attention to her than he was to the girl his cock was buried in! I could literally see the confidence building in her as she licked her lips and put on a sexy little pout, all designed to tease and flirt and all successful as hell. My oh my, this girl was a natural slut! My dad gave us one last look and then turned to Tammy.
