Chapter 3: Getting Started in the Hot Tub

Incest Sex Story: Chapter 3: Getting Started in the Hot Tub - My cousin Tammy was now sixteen years old and my, how she'd grown up since we first started having sex a couple years ago! As she gets older it's become harder and harder for my dad to find an excuse to spend some private "quality time" together. Well, what could be better than to have her spend the night with me on a "sleepover"? I doubt her mother would have approved if she knew who Tammy really was going to be sleeping with.

It was only a short while and we were back home and I led her to my room to change into something more comfortable. Tammy, though, had other ideas.

“Hey Kelly, can we go in the hot tub first?” she asked, her eyes bright and a big smile on her face.

I didn’t see any reason why not so we just stripped and grabbed some towels from the hallway closet and headed downstairs to the hot tub. This was one of the few times I ran through the house naked - between my bedroom and the hot tub. It didn’t make any sense to put on anything just to take it off less than a minute later. So far as I knew I’d always used the hot tub nude unless we had company over. It was just one of those things we did as a family, not meant to be sexual.

Of course, that didn’t mean the tub wasn’t ever used for sex. Indeed, the first time I ever saw my parents making love was looking down from my bedroom window onto the deck and seeing them in the tub together. After I started having sex with my dad, that opened new doors as well. When my friends came over, most of them enjoyed being nude too - although they stayed dressed when my dad was home. More than a few boys I dated got to spend some time with me in our tub as well. The look on their faces when I just stripped and hopped in was priceless!

I remembered when Tammy and her family would visit and we would all use the tub (in our suits, of course). When Tammy got to be around twelve or so and started to fill out in all the right places, I would reach under the foam and feel my dad’s erection under the water. He use to get SO horny when she ran around in her swim suit, even it is was rather conservative because of her mother.

Tammy helped me pull the cover off and I started up the jets. The water was hot and even thought the sun was out and it was a hot day, it still felt good to climb in and feel your skin tingle from the heat of the water. I slowly lowered myself in as Tammy did the same. I couldn’t help but notice she was developing into quit the looker! Her boobs were definitely filling out, maybe a solid B cup by now. She was a little heavier maybe than she should be but not fat by any means. She had wide tans lines from the conservative two piece suit her mom made her wear. Actually, I was amazed she ever let her wear THAT as until the past year or so all she could wear were one-piece suits.

“Wow, it’s so hot!” she exclaimed as the water went over her chest and up to her neck. Indeed, it did feel a little hotter than usual but that was probably because we were already so warm from the sun before we got in.

I felt the jets striking me from all sides and I recalled the first time I figured out what other things the jets were good for. We had the standard shower massager in the bathroom (why do you think women all want them?) but the jets did a much better job as they were more powerful and the force of them against my pussy was absolutely delightful!

We just chatted for a while as it had been quite a while since the two of us had been alone together. She was really curious about my boyfriend Duane and I guess I couldn’t blame her. It had been a long time since I had a real “boyfriend” and Duane was special. I could actually see him proposing to me someday - and me accepting!

“So does he fuck you good?” she asked with a naughty grin, reaching over with her foot to rub my leg.

“Oh yeah!” was all I said in response, my smile telling her more than anything I could say.

“Does he know...,” she started to say, dragging it on as if not sure she should be asking.

“You know better than to even ask that,” I replied, maybe a little too sharply and then added, “Someday if and when he proposes I will. I don’t want to be like Aunt Linda.”

She knew what I was talking about. My Aunt had agreed to get married and thought her new husband was cool with her lifestyle but soon found out he couldn’t handle it. Their marriage lasted long enough to bring Kristen into the household but not long enough for her to ever know her father. When he gave her an ultimatum, stop having sex with her family or he would leave, she handed him a suitcase. Family came first with her as it did with me. As much as I loved Duane and dearly hoped someday we might be married, if he wasn’t ready to accept me for who I am then it would never come to be.

“Hey ... Rick’s been over here a lot lately,” she said, changing the subject. “Who does he do the most, you or your mom?”

“You mean he doesn’t brag about it when gets home?” I chuckled.

“Oh sure but I never know what to believe with him sometimes. He claims that he just fucks you mom. Is that true?”

I nodded at her and shrugged my shoulders. “It’s OK, my mom gets a kick out it. So what about you? Have you been a good sister lately?”

Her eyes lit up again and she smiled broadly. “Not so much him as some of his friends. He has some really cute guys he hangs around with and now that they know he has a sister like me, they seem to want to come around more often. Hmmmmmm, I wonder why?”

She said that last part with such an innocent look on her face, as if she had no idea why a bunch of guys would want to come over to fuck their friend’s sixteen year old sister, that we both burst out laughing.

“What about your girlfriends? Anything happen there lately?” I asked.

Tammy had never really gotten into girl-girl sex, even though I was the first one to eat her pussy. Sometimes I think she let me play with her more to please me than her and over time, we had sort of gotten away from it. In fact, it had been ages since the last time we played together, maybe last Christmas?

“Nah, I like boys, you know that,” she reminded me, then looked at me with a haughty grin and then added, “Of course, present company excepted.”

“Get over her silly,” I said, motioning for her to move closer to me.

Tammy turned her back to me and I put my arms around her and pulled her in tightly between my legs/ She was quite a bit smaller than me still, even smaller than Kristen was. I felt her naked body between my legs and then the pressure of her pushing against my pussy and felt a chill run up my spine, even with the hot jet pumping out against it.

“Ready for a little jet action?” I asked, twisting around without waiting for a response.

I turned so she was facing the side of the hot tub. This wasn’t the first time we’d done this and she knew the drill. She lifted her legs up and out of the eater, draping them over the side of the tub so her crotch was up close to the jet that was shooting out air and eater. I supported her from behind so she wouldn’t dunk under the water and she spread her legs apart so the jet pulsed directly against her bare pussy.
