Fulfilling my Lustful Fantasies

"I want to do it there" I pointed to a smooth slab of rock, in the distance. The rock I mentioned was strangely smooth, perfectly smooth in fact, because it is in fact not a naturally formed rock. I had Celine cut it to this shape before, when I made her do splits while naked, and had shake her ass in front of my face.

"Oh, you really love that place eh?" It seemed that she also remembered that time I made her 'stretch' there.

I placed a towel down and laid down face up, and I looked at my sister still standing thinking on how she would clean me without using her arms or legs. It's pretty simple actually, without her limbs the only body part she could realistically use to scrub me with, is her abdomen, chest, and her butt. And I don't think she can use her abdomen that easily especially when I'm lying down like this.

Casting a Water Sphere, she poured water on herself by dropping it on top of her. I watched the water flow down her smooth body, especially the ones on her perky tits. She seemed to have arrived at the same answer, as she started lathering her breasts with soap, as she placed each of her legs at my side before going down on all fours, with me under her.

I felt my dick harden, as I saw her tits hang from her body, soap and bubbles dripping down from her pink nipples. Finally she lowered her chest, and started scrubbing my chest earnestly in up and down motions. Her platinum hair fell at the side of her head, as our face was just in front of each other. She gave me a peck on the lips, before resuming her work. However she couldn't hold for long as her arms were starting to get numb from supporting all of her body weight. So she decided to rethink her approach.

However from our current position, when she sat upright her soap covered ass directly landed on my hips.

"Ah~" I unconsciously moaned as the pleasure of her soft, springy ass was just too much for my hips, not too mention my dick got buried on her butt crack, as I felt her ass cheeks sandwiching it. She then wiggled her butt sideways, as she tried to get into a more comfortable position. The feeling of her slippery butt crack on my dick was so pleasurable, that I wanted to have her stay at this position a little while longer.

"Oh yeah, why didn't I think of that earlier!" I heard sis exclaim

I knew it wasn't going to happen as soon as I saw her lift her ass and stand up. She seemed to have taught of a good idea, as she had her eyes wide before quickly getting the soap bar. I was shocked as this time instead of her chest, she lathered herself from her butt crack all the way somewhere just above her clit. Not only that she made sure her inner thighs was bubbling with soap, and didn't forget to add some on her ass cheeks as well.

And unlike before instead of going kneeling down on all fours, she squatted down sitting her ass directly on my hard dick. As I thought I knew what she is gonna be doing next, I quickly covered my mouth with my hand, to prevent her from seeing my facial expressions. And just as I expected, she started grinding her hips against mine.

Behind my hands, I was clenching my teeth, as the pleasure I was feeling started to build up. It seems she plans to move upward from my hips before going to my chest. The problems was every time she moved her hips, as if the soft, bouncy, and slippery feeling of her ass wasn't enough, ever so often my dick would feel something moist and warm, in contrast to the cool and smooth skin surrounding it. And I would be stupid to not know what that was.

I was trying my best to keep my facial expressions straight, as the last thing I would want now is for her too see my face in bliss. Sis would definitely try to find out more about why that happened, and if she ever finds out about sex and connects it with what I've been doing to her all this time. Then all my plans will go down the drain. The only way she should remember what she is doing to me right now, is that she cleaned my body without using her arms and legs and that's it.

Luckily as we were only using soap bars, the bubbles disappears pretty quickly and she would have to reapply them ever so often. That was enough of a breathing space for me. But that didn't make it any easier, aside from the physical stimulation, there was also the mental pleasure of having my usually proud and smug elder sister, unknowingly pleasure my dick.

"Fufu, well Riel this was easy." Sister said smugly while panting, her beautiful eyes slanted, and her wet platinum hair was glistening in the Sun. It seems she's done 'washing' my hips, so she moved upward towards my chest.

Ah fuck, Just this.. A few seconds ago my dick was buried in her butt crack and here she is, acting all smug as she found out an 'easy' way to do the 'dare' I gave her. Luckily she's 'cleaning' my stomach this time so the physical pleasure lowered a bit. But still the feeling of her smooth ass, sitting on top of me, sliding around my body is enough to keep me on the edge. Not to mention unlike earlier, when she was grinding my hips, this time it's her perky tits which are hanging right above my eyes, giving me quite the visual stimulation.

As she finished around my chest she took away the hands that I was using to cover my mouth, I thought I would be turning over to my back, but to my huge surprise she placed both my hands above my head before pinning them down. she continued upwards towards my face. Her pussy lips was just above my face, but then I felt something drip down my face. I took a deep breath, filling my nose with the scent of her aroused pussy. Her pussy lips which I usually saw as a straight line was slightly open, and I have a perfect view of what's inside, Including her meat hole, which was opening and closing repeated like it was breathing, as if begging me to stick something inside, as she was dripping light juices.

And a few seconds after, she finally lowered herself, as I felt her soft pussy move across my face before feeling her soft bouncy ass. That was the finals straw for the virgin me, as I felt myself bust one out. My face finally relaxed after trying to hold out all this time. Luckily I no longer needed to cover my face with my hands, as she decided help me do it by covering it with her pussy instead. However I felt nothing come out from my dick. Is it due to the fact it is my first time busting one out in this life? Well it seemed that way. At this point I just said, fuck it. And every time her pussy passes my mouth I give it a lick. Sister also seemed to have felt it as after some time, it was just her grinding her pussy on my tongue.

When sister was finally done ridi- I mean, 'cleaning' my face, she finally stood up.

"That was a breeze Riel and here I am thinking you've got a better challenge for me. Fufufu, please think of something more difficult next time, if you'll win against me again that is." Celine boasted, her face really couldn't look any more smug. She then walked away to change to her spare clothing.

I too changed into my spares, I was back to my acting self. I made sure to act like I was down, and when big sis saw me looking downhearted, she didn't say anything but instead she suddenly lifted me up before putting me in a piggyback carry. I then buried my head in her hair remaining silent through the rest of the journey.

However I was actually ecstatic inside, as I gained something I didn't expect. Just like how I used breastfeeding as an excuse to slowly have my way with Mother's tits, I have found the way in which I could slowly have access to my elder sister's sweet round ass.
