Chapter 3: Tammy and I Suck Her Brother’s Dick
Incest Sex Story: Chapter 3: Tammy and I Suck Her Brother’s Dick - My dad had been dreaming of having sex with Tammy, his youngest niece (my cousin) for years as she matured from a skinny little runt into one sexy teenage girl. As one of my deepest regrets will always be that I didn't give myself to my father first, I thought maybe I could make it up to him a bit by helping him realize his dreams about Tammy. Whether or not his brother cared didn't really seem to matter.

The rest of the trip was rather uneventful and we finally reached the park as dusk was settling in. My dad and uncle checked in and came out with the keys to our cabins. We all drove down the winding dirt road to the cabin area. Each of the parents had their own one-bedroom cabin while the rest of us were to share a two-bedroom cabin. Each of our bedrooms had two twin beds and Kate, always the crybaby, whined that she and Tammy had to share a small twin bed while Rick had a whole bedroom all to himself.
“No don’t get yourself all worked up Kate, Tammy can sleep with me,” I volunteered. Kate didn’t even wait for anyone to answer before dumping her sister’s stuff onto the other bed where mine was. My aunt thanked me for helping out but little did she know why I really wanted her daughter in bed with me! We all got ourselves arranged while my dad and uncle went down to the docks to check out the boat. They returned shortly and confirmed that everything was ready to go for the next day. By now everyone was pretty tired and it was pitch black outside so we decided to have a campfire the next night and just get to bed so we would be rested in the morning. Rick went into his room and as he shut the door, I saw him looking at Tammy. He smiled and winked at her and then closed the door. Kate didn’t see any of this but I wondered if Rick and Tammy were this blatant about things at their house. God, if Kate or her mom had the slightest idea of what Rick and Tammy had been doing they would’ve had a fit!
Once we were in our room alone, we all got undressed and slipped into our night clothes. I would’ve loved to sleep nude with Tammy but with Kate in the same room that wasn’t an option so instead I’d opted for a T-shirt which covered my ass - but not by much. Tammy was wearing a similar nightshirt but hers was much longer and reached below her knees. Interestingly I noted she had taken off her panties but not put any fresh ones on. Hmmm, I wondered if Kate had noticed? Obviously not since the little prude would undoubtedly have said something about it.
Speaking of prudes ... Kate opted for the full pajama set with pants and a shirt. Of course she was wearing her panties underneath and I thought for a moment she was going to keep her bra on until she removed it at the last minute. even then she turned her back to us when she did and had her shirt ready to put on so I didn’t get even a glimpse of her bare boobs. It wasn’t that I really cared to see them, it was more the principle. She and Tammy got in their respective beds after which I turned off the light switch by the door and then crawled in beside Tammy. As you might imagine It was pretty close quarters sharing a the twin bed but she laid on her side and I climbed in behind her, the two of us basically in a spooning position with me being the big spoon and Tammy the little spoon.
Wow, it was totally dark in the room as the curtains were pulled and there was no night light in the room or even a clock to provide any illumination. Oh well, that was just fine with me! I put my arm around Tammy and pulled her in tightly to me. She wiggled and squirmed to press her cute little ass tightly in against my stomach, in the process making her T-shirt ride up a bit after which I helped out by reaching down and pulling it up over her slim hips. The covers were over us so even if a light should suddenly come on nobody could see what was happening anyway. My own T-shirt had ridden up the moment I had gotten into the bed and I didn’t bother pulling it down so the result was Tammy’s cute little bare ass was now pressing against my bare stomach. Mmmmmm, she felt so warm and smooth against me!
It wasn’t like there was any need to take my time so my hands almost immediately slipped under her T-shirt and I caressed her boobs which were finally started to develop from little knobs on her chest to actual breasts. They were still small enough for even my hand to fully encompass but the nipples responded to my touch and hardened to become like pencil erasers. She placed her hand firmly over mine through the single layer of thin cotton and we laid there like that until I fell asleep.
For some reason I woke up a while later and for a second I was unsure of where I was in the dark until finally it came to me I was in the cabin at the lake and not in my bedroom. As my mind cleared I realized I was alone in bed and again it took a few seconds for me to remember that Tammy was supposed to be with me. Now where had that girl gone? Instantly the answer came to me and looked over to where Kate’s bed was. The moon had risen and a sliver of light was shining in between the curtains, just enough for me to see the lump in her bed where she was sleeping soundly.
With Kate safely asleep I silently got out of bed and slipped out of the room, closing the door behind me and walked across to the other bedroom. The door was closed but when I placed my ear to the door I could definitely hear that something was going on and I had a darn good idea what it was! I carefully opened the door and peeked through. The drapes were open in his room and with the rising moon there was enough light now for me to get a pretty good view of the room. Sure enough, right in the middle of one of the beds was Rick and his little sister Tammy. As usual, Tammy was on top of Rick in a classic 69 position and while I couldn’t see much more than their outlines, it was obvious from the way her head was bobbing she was giving Rick’s cock quite the workout!
The horny brother and sister were too occupied to notice me sneaking into the room and I slowly closed the door behind me again. My eyes were adjusting to the low light now and I could better make out the two of them. Both Tammy and Rick were completely nude and I couldn’t help but admire how Tammy’s cocksucking techniques had improved. I knew she had been getting lots of practice and it just goes to show practice makes perfect. She still didn’t seem to quite have the deep-throat thing down though as she was only taking a little over half of his cock into her mouth. Rick certainly didn’t seem to mind! He had both hands on Tammy’s ass and was pulling her butt cheeks apart to get a better look at her pussy and asshole. He head was buried in her ass and in the dimness I couldn’t quite tell if he was licking her pussy or her asshole. Tammy was using one hand on the base of his cock while she tried to hold herself up with the other. She looked so small on top of him! Rick had just turned eighteen and was built pretty well while Tammy was not only four years younger but petite even for her age.
As I watched I felt my pussy beginning to get that feeling it always does when I start getting horny. I reached down and lifted up my T-shirt to get to my crotch. Damn if I was already soaking wet already! I touched my clit and an involuntary gasp erupted from me as it was like I had taken an electric cord and touched myself there. Tammy’s immediately lifted her head, dropping Rick’s cock from her lips as she looked over in panic to see who it was. When she saw it was me she grinned and went back to work on Rick’s cock.
Rick evidently hadn’t heard me or else he was engrossed in Tammy’s ass that he didn’t care who had come in because he didn’t stop for even a second. I made my way slowly across the room, pulling off my T-shirt and tossing it on the spare bed as I passed by. I wasn’t sure which was turning me on more - seeing her swallowing his hard cock or wishing I was licking her pussy. It didn’t take me long to make up my mind what I wanted though.
“C’mon, don’t be selfish. Let me have a taste of that cock,” I whispered to her as I bent over the bed.
Tammy looked up at me with her brother’s cock in her mouth and shook her head as she took him even deeper in her mouth. She was grinning as best as she could with her little mouth filled with dick and I knew she was just trying to tease me so I reached out and took his balls in my hand. I gently rolled them in my hand and massaged them, feeling the thick pubic hair in my hands that surrounded them which was damp with his sweat and her spit from sucking him. After I played with his balls for a while I moved up and took the base of his cock in my hand and gently stroked him in rhythm with Tammy’s BJ. Finally I just couldn’t take it any more - I simply HAD to have that cock!
“C’mon Tammy,” I said in a firmer tone, “Let me have it for a while.”
Tammy looked me in the eyes again but this time she winked at me and lifted her head enough for his cock to slide out from her lips. Rick was impatient, though, and before I could lean down to suck him I heard grumbling.
“Look, how about at least ONE of you sucking my cock?” he whined. Tammy turned her head around and snickered at him.
“Hang in there big brother,” she scolded him, “Besides, I don’t remember saying you could quit licking me!”
Sometimes seeing them like this I would forget they were brother and sister but listening to them bickering reminded me again of their true relationship. I ignored their playful banter as the sight of his hard cock sticking straight up in the air was all I wanted to think about. It had been a while since I sucked him and I couldn’t wait to take him in my mouth again! I licked the tip of Rick’s cock playfully, running my tongue in tight circles around his cock head and then up and down the length of his beautiful dick. He was still wet from Tammy’s BJ and so I took the tip of him in my open mouth and sucked on the head like it was a hose and I was siphoning gas with it. My cheeks sucked in and I pulled up on his cock with my mouth, stretching him up from his crotch.
In the meantime, Tammy had simply sat up straighter and was grinding her ass in Rick’s face, twisting back and forth as she rotated her cute little butt like a hula dancer. She looked incredibly cute with her puffy boobs and perky body, sitting all nice and nude on her brother’s face. I was so proud of my little protege!
Releasing the suction on his cock, I lowered my head further down onto him, slowly taking his cock into my mouth inch by inch until finally my face felt his curly pubic hair brushing against it. His crotch smelled like a mixture of sweat and sex which at the moment was just perfect so far as I was concerned. I buried my face in his pubic hair and twisted my head around on his cock which was now pressing against the back of my throat.
“Oh god!” I heard him groan, “Suck my cock Kelly! Damn you know just what to do ... Ahhhhhh, take it all!”
Indeed I did. I’d sucked his cock more than a few times and by now I pretty much knew just what he liked. When it comes to blowjobs every guy is unique and if you really want to please them then you had to be conscious of how they react when you first started sucking their dick, figuring out what they like best.
Face it, I think I could just bob my head on most guys and they would be happy but that’s not how to build a good reputation for giving a BJ. After all, I wasn’t known as the best cocksucker in school for nothing! You just have to be sensitive to the slightest movements that tell you when he is getting turned on more or less. Sure, every guy groans and bucks every now and then. Even the most basic blowjob can do that to a guy as it doesn’t take much to make a cock hard - they are pretty simple things when you get down to it. When I feel him twitch in my mouth, his stomach tighten, or his ass clench just that little bit, it tells me that I have hit a sweet spot. Most guys love a tongue against them when it’s in the right spot. The trick is to keep sucking him at the same time whereas most girls just suck or lick and don’t take advantage of the effect you get from doing both at the same time.
Rick was getting close to cumming but I wasn’t ready for that yet so I had to drop him from my mouth. I got up on my knees on the bed and lifted one leg over him so I could straddle him.
“You sure you don’t want him to fuck you instead?” I asked Tammy as I positioned myself over he brother’s cock. As I expected, Tammy just shook her head. For some reason she was pretty adamant that she didn’t want Rick to be her first. Whatever it was, she had never told me. It wasn’t just a sister- brother thing either as so far Tammy had never let any of his friends fuck her either even though she was more than willing to suck their cocks all night.
My first guess was that it was not so much “who” as “when and where”. I think every girl dreams about her first time and Tammy obviously had some big dream sequence worked out where her Prince Charming would ride in and take her virginity. At the moment it didn’t really matter to me as all I wanted was Rick to fuck me - and fuck me sooner than later!
“Here, you put his cock in me,” I whispered to Tammy.
She didn’t hesitate, reaching down and taking his cock in her right hand and positioning it under my cunt as I slowly lowered myself down to meet it. Tammy playfully rubbed the tip of his cock against my pussy, easily parting my wet pussy lips and then rubbing it against my clit. I couldn’t help but smile - the girl remembered her previous lessons well!
“Hold it still,” I told her. I was still on my knees, straddling him with my pussy hovering just over the tip of his dick. Tammy dutifully held his cock firmly in place and I let myself sink down slowly onto it. The head of his cock head pressed against my tight pussy hole and as stiff as he was, his cock still bent slightly as my pussy resisted him. I sat down harder on him and suddenly my pussy gave up and I felt myself splitting open as his cock pushed its way into my pussy hole like an invading army breaking down the castle gates. The moment I felt him enter me I stopped dropping down and his bent cock acted like a spring to push himself an inch or so inside of me without me having to push down any further.
